More Than Defense in Daily Experience of Privacy: The Functions of Privacy in Digital and Physical Environments

The purpose of the current study was to investigate the experience of privacy, focusing on its functional role in personal well-being. A sample (N = 180) comprised subjects between 18 and 50 years of age were asked to spontaneously provide accounts of their experiences with privacy and answer close-ended questions to acquire a description of a daily experience of privacy. The results showed the importance attributed to the function of privacy related to the “defense from social threats”, and the twofold function of privacy related to an “achieved state of privacy”, in the terms of both “system maintenance” and “system development”. The results also shed light on the role of the environment in shaping one’s experience of privacy. Specifically, the participants recognized more easily the function of defense from threats related to seeking privacy while interacting in digital environments, whereas they seemed to benefit from positive functions related to an achieved state of privacy in physical environments. The findings sustain the notion of privacy as a supportive condition for some psychological processes involved in the positive human functioning and confirm previous studies conducted on the role of privacy in human well-being.

which the subject seeks it (Newell, 1998), the affective state related to its achievement (Francis & Cooper, 1991;Newell, 1994) and the perceived ability to achieve it, have been investigated in previous studies.
Specifically, the proponents of the approach related to the "why" of privacy (Newell, 1994(Newell, , 1995(Newell, , 1998Pedersen, 1999;Westin, 1967) make a point, which appears to be relevant for the purposes of the current work. They argue that privacy has two main functions for human well-being, (a) a system maintenance function, which involves cognitive and emotional processes implicated in the maintenance of the homeostasis and in a state of release and (b) a system development function, which comprises psychological processes, such as self-conscious processes, involved in personal growth (Cole & Hall, 2010;Hammitt, 2012;Newell, 1998;Pedersen, 1999). As a system maintenance function, privacy supports processes to promote and ensure a satisfying level of homeostasis (Cannon, 1932), since it is often associated with the experience of recovery from psychophysiological stress (Ulrich et al., 1991), emotion regulation (Izard & Kobak, 1991), self-regulation and release (Korpela, Kyttä, & Hartig, 2002;Vuorinen, 1990). Reframing the discourse on this topic to reflect the approach of positive psychology, it is possible to state that this type of experience may be associated with the hedonic experience (Kahneman, Diener, & Schwarz, 1999) and the related concept of subjective well-being (Diener, 2000), which focus on positive affect and the absence of unpleasant experience. As a system development function, privacy provides the condition to exercise and improve self-conscious processes, like self-evaluation, contemplation of one's thoughts and emotions (Long, 2000;Long & Averill, 2003;Pedersen, 1997Pedersen, , 1999, problem-solving, creative thought (Edney & Buda, 1976;Ittelson, Proshansky, Rivlin, & Winkel, 1974;Newell, 1994), and spirituality (Pedersen, 1999;Suedfeld, 1982). In this regard, for example, Pedersen found that some psychological processes involved in the positive functioning, such as selfdiscovery and planning, are best supported by specific privacy forms, such as solitude and isolation conditions, rather than other forms, such as either intimacy or anonymity conditions (Pedersen, 1997).
Considering the positive psychology point of view on this topic, the system development function underlies the idea of well-being as a complex long-term-oriented process of self-development and growth. Thus, privacy presents a particular focus on personal growth (Keyes, 2002;Seligman & Csikszentmihalyi, 2000). This approach to wellbeing is particularly close to the idea of psychological well-being (Ryff & Singer, 1998, 2008, which underlines the positive factors that empower individuals to fulfill self-actualization (Ryan & Deci, 2000).
Following this process approach to privacy, the current study aims to focus on two types of function of privacy: the function of protection from threats and the function related to an achieved condition of privacy. The former is a prerequisite for the achievement of a state of privacy. Compared to the latter, it has attracted the most scientific attention so far. The second category comprises the beneficial functions provided by an achieved condition of privacy, such as the system maintenance and the system development (Newell, 1994(Newell, , 1995(Newell, , 1998. Despite the limited extant studies on the benefits related to the experience of privacy, scholars agree on emphasizing the relevance of experiencing privacy for the empowerment of well-being (Cole & Hall, 2010;Long & Averill, 2003;Newell, 1994Newell, , 1998Pedersen, 1997Pedersen, , 1999.

The Role of the Environment in Shaping the Concept of Privacy: Digital Spaces vs. Physical Environments
First, the issue of privacy has been applied to the digital space domain. In the current study, we used the term "digital environment" to indicate technology-based social interactions, such as computer-mediated-communication (CMC), social-network interaction and communication via media and new media (Palen & Dourish, 2003;Sommer, 2002;Tu, 2002b). Information technologies have contributed to the creation of new sets of problems; specifically, they have created a ubiquitous environment where sensible constraints are no longer perceived. Hence, social interaction becomes difficult to manage (Bellotti, 1998;Grudin, 2001;Neumann, 1995;Tu, 2002b), since it has been related to multiple changes in boundary regulation practices (Boyle, 2003;Boyle, Neustaedter, & Greenberg, 2009;Palen & Dourish, 2003). Consequently, an increase in sensitivity to the risks of violation of one's personal information has occurred (Cole et al., 2001;Röcker & Feith, 2009). From this perspective, the issue of privacy is associated with the problem of managing the information shared about oneself (Altman, 1975(Altman, , 1977Röcker & Feith, 2009).
A second line of research considers the influence of the physical environment in determining the features of an experience of well-being (Cole & Hall, 2010;Hammitt, 1982Hammitt, , 2012Kaplan, 1995;Korpela, Hartig, Kaiser, & Fuhrer, 2001;Korpela et al., 2002). From this perspective, the concept of privacy is useful to illustrate the kind of experience that people seek in particular contexts (e.g., in the wilderness) (Hammitt, 2012). In his study, Hammitt (2012) showed that wilderness privacy operates as a coping strategy to achieve a desired environmental state, as it works as a boundary regulation mechanism, which serves to fit with one's needs for space and social interaction (Altman, 1975;Proshansky, Ittleson, & Rivlin, 1976) and for experiencing emotional and cognitive release (Westin, 1967) from everyday stressors and fatigue. Indeed, it is easier to identify strategies to take advantage of the beneficial functions of privacy to experience well-being in the physical environment rather than in this ubiquitous environment, since the former provides well-known sensible coordinates in which one can move in order to manage his/her social activities.
Considering the points made in the present discussion, some relevant questions about the function of privacy and the role of the environment in shaping its experience emerge.
First, it may be interesting to examine the processes related to the functions of privacy as well as the experience of its beneficial effects, as pointed out in the literature.
Second, studies on both the digital and the physical environment reflect two main traditions of research on the topic of privacy in psychology. The "how" of privacy is particularly critical for research on the previously mentioned digital environment. The branch of work concerning privacy in the wilderness and the restorative experience in natural environments can be seen as part of "why" line of research. It would be interesting to go beyond the opposition between negative-positive experiences of privacy in relation to digital vs. physical environment through the investigation of the experience of the person-environment interaction in both types of environment.

Aims of the Study
The primary purpose of the current study was to investigate the experience of privacy, with a focus on its functions for well-being (i.e., the functions of threat defense, of system maintenance, and of system development). Hence, Specifically, we intended to (1) investigate the relevance attributed to each of the two categories of function of privacy, such as the function of defense of the system and the function related to the achieved state of privacy (i.e., function of maintenance and function of development).
Hence, we expected that (a) the function of defense of the system would be mentioned more frequently compared to the function related to a state of achieved state of privacy (i.e., system maintenance function and system development function), since the aspects associated with the protection from threats are easier to identify in one's daily experience of privacy, and the defense processes take priority over the psychological processes related to an achieved state of privacy (Cannon, 1932;Newell, 1994).
Second, we also expected that (b) considering the two functions related to the achieved state of privacy (i.e., the function of maintenance and the function of development), the function of maintenance would be cited more frequently compared to the function of development, as the effects related to the psychological processes involved in the maintenance of the system, (e.g., the effect of recovery from threats and emotional regulation) are easily to be detected compared to those involved in the development (e.g., the result of self-evaluation and contemplation of one's thoughts), which comprises long-term processes.
Second aim of the current work was to (2) investigate the role of the environment in shaping the experience of privacy.
According to the literature (Boyle, Neustaedter, & Greenberg, 2009;Palen & Dourish, 2003;Tu, 2002b), we expected that (c) the aspects associated with two positive functions related to a state of achieved privacy would be mentioned less frequently in relation to digital rather than physical environments, since in digital spaces, managing the threats of violation of one's privacy (i.e., function of protection from threats) is of much concern (Boyle, Neustaedter, & Greenberg, 2009;Palen & Dourish, 2003).

Method Participants and Procedure
The sample comprised 180 Italian volunteer males (n = 90) and females (n = 90) between the ages of 18 and 50 (M = 32.26; SD = 10.807). The subjects were heterogeneous in terms of education (bachelor's degree = 44.44%; high school diploma = 48.33%; middle school diploma = 7.22%) and occupation (student = 28.89%; employee = 52.78%; freelance = 18.33%). The participants were recruited via the Internet. All subjects were Italian and currently living in Italy.

Instruments
We used two instruments to conduct a free exploration and obtain a guided detailed description of the daily experience of privacy.
The first instrument comprised open-ended questions to investigate the sample's social representation of privacy through their spontaneous definitions of privacy (Foddy, 1993;Reja, Lozar Manfreda, Hlebec, & Vehovar, 2003 The second instrument was a modified version of an ad hoc privacy questionnaire developed by Newell (1998).
It comprised two sections. The first section assessed demographic variables, including age, gender, education, and occupation. The second and final section of the instrument included close-ended questions. These questions assessed the main features that characterize the process of seeking privacy. (a) The antecedent conditions connected to a desire for privacy were assessed. Past research (Newell, 1994(Newell, , 1998Pastalan, 1970) identified the following antecedent conditions: "Social antecedents", referring to the concerns for other people, such as overcrowding, need for intimacy, and perceived responsibilities to other people; "Physical conditions", referring to physical factors, which, if experienced, may require the achievement of privacy, such as noise and pollution; "Motivational antecedents", referring to intentions and desires to do or achieve something; and "Organismic factors", referring to disturbance in the physiological state of the individual that is unrelated to immediate social conditions, such as major injury, aggression, anxiety state, inability to control one's action, menses. (b) The affective set linked to a requirement of privacy was assessed as another feature of privacy seeking (Newell, 1994). The affective set categories used in past research (Korpela 1991;Newell 1998) included sadness, anger, anxiety, tiredness, positive state, creative thinking, desire to focus on one's thoughts and desire of intimacy related to a previous condition to the achievement of privacy. (c) The after affective effects of the achievement of privacy (Francis & Cooper, 1991;Korpela, 1989Korpela, , 1991Newell, 1994Newell, , 1998 were derived from past research on privacy experience as well as restorative places. Categories include relaxation, emotionality, tiredness and refreshments experienced after the achievement of a state of privacy. (d) The perceived ability to achieve privacy and (e) the urgency with which the subject seeks privacy (Newell, 1998) are the primary driver of seeking privacy and consider the following options: distress, concentration, need for creative thinking, and need for intimacy. Questions related to the duration of the average experience of privacy, the frequency of the occurrence of both a need for privacy and a need for sharing a privacy experience with others were not included in the current version of the instrument.
The original version of the questionnaire (Newell, 1998) was translated into Italian.

Data Analysis
The present study used a quali-quantitative analysis of the answers to the open questions. To explore the primary features of the sample's concept of privacy, the textual corpus obtained from the answers was systematically analyzed using the T-lab 7.2 software for content analysis and text mining i . The choice of this instrument was justified by the fact that it allows investigating both the inner structure of a semantic map and the process of meaning making (Lancia, 2004). After the text corpus was set up, two kinds of textual analysis were conducted.
First, a cluster analysis, respectively called "Thematic Analysis of Elementary Context", was performed (Guest & McLellan, 2003;Richards & Richards, 1995). This analysis made it possible to identify the principal themes associated with the sample's social representation of privacy and their localization into a semantic space. This semantic field was drawn up by the interception of two axes explaining the thematic variance of the considered corpus The Positive Side of Privacy: Functions for Personal Well-Being 120 (Gambetti & Graffigna, 2010). Specifically, the main isolated clusters consisted of Elementary Contexts (EC).
Each EC had the minimum degree of inner variance and the maximum degree of the external one. Second, a cooccurrence analysis, which is called "Word Association Analysis" (WAA), was conducted to obtain a more precise exploration of the semantic association between some of the principal key words (i.e., Lexical Units, LU) to determine their local meaning. The relationships were measured with a semantic association index (Cosine Coefficient, Salton & McGill, 1984).
The main features that characterize the experience of privacy collected through closed-ended questions were analyzed to explore the sample's daily experience of privacy. Chi-square analysis was applied to compare the data on the system maintenance type of function of privacy with those on the system development function (Newell, 1994(Newell, , 1998.

Occurrence of Omitted Answers
The

Cluster Analysis (CA)
The Thematic Analysis of Elementary Context was carried out on the entire textual corpus, which comprised the answers to the three open-ended questions included in the questionnaire. This analysis allowed for the creation of a semantics map through the individuation of two main factors that were used to organize the amount of textual data (see Figure 1).

•
Factor 1 represents the locus of control over private information ("internal locus of control-external locus of control" axis in Figure 1). Locus of control is external if the person perceives himself or herself to play a passive role in the management of his or her private information (right extreme), whereas it is internal if the person feels that he or she holds active control over this information (left extreme).

•
Factor 2 represents the level of awareness about one's own experience ("awareness-unawareness" axis in  The mapping of the above criteria resulted in the isolation of five thematic clusters in which the corpus was organized (see Appendix). The first cluster deals with the negative experiences of invasion of privacy via media and new media (e.g., telephone, the Internet, e-mail, and Facebook). These types of experiences increase the perception of violation of privacy due to the subject's unawareness of the means by which an unknown person can obtain the subject's personal information (e.g., telephone numbers, personal account information and other identifying data).
The second cluster focuses on the management of private information by others. This cluster includes experiences through which the respondents entitle other persons to handle their own data. The management of private information by third parties can be proper or improper, such as, for example, publishing school results or speaking loudly during a medical examination.
The third, fourth, and fifth clusters deal more directly with the definition of privacy. The third cluster focuses on the experiential and concrete features of privacy. When privacy is achieved, participants have a positive experience; they consider privacy a physical space in which one can exert free will and perceive a sense of agency.
The fourth cluster focuses on a dialectic definition of privacy as a condition of "the lack of privacy violation". This cluster includes elementary context, which defines privacy as a condition in which "nobody bothers me", "my secrets are protected", "nobody violates my personal space", "nobody can read my personal diary", and the like.
The fifth cluster centers on the normative aspects associated with privacy. Typical terms in this cluster concern the semantic field of protection and defense against violation of sensitive data. Specifically, the individual protects the data him or herself. The Positive Side of Privacy: Functions for Personal Well-Being

Word Association Analysis (WAA)
A Word Association Analysis was conducted to specify and support the outcomes obtained from the CA (see Table 1). Specifically, the associations between the concept of privacy and other concepts related to the entire corpus were studied and measured using a Cosine Coefficient (CC, Salton & McGill, 1984). Considering the four most significant associations with the concept of privacy ("life", "violation", "personal", and "respect"), the results showed that privacy can be represented through three primary semantic dimensions. First, the sample seemed to acknowledge that privacy concerns the most intimate aspects of life and is linked to their daily experience Therefore, the considered association justifies the hypothesis that the concept of violation is often activated when the respondents think about privacy.

Guided Exploration of the Experience of Privacy
Considering the conditions that stimulate the subject to achieve privacy ("antecedent factors to privacy"), most participants (N = 180) indicated "social factors" as the first (43.89%) and "motivational factors" as the second (27.22%) reason to pursue privacy, followed by "physical factors" (11.67%) and "organismic factors" (10.00%).
The "urgency" factor concerns a set of aspects that explain the subjective need to achieve privacy. A large portion (41.11%) of the total sample (N = 180) indicated "concentration" as the main reason and "stress" as the second reason (32.78%) to seek privacy.
Furthermore, the findings suggested that privacy is mostly sought for reasons concerned with "system development" (total development = 58.89%) rather than "system maintenance" (total maintenance = 40.56%) ( Table 2). These reasons differed significantly, as indicated by a chi square of 6.084 with 1df and a p-value of 0.014.

Affect Associated With Antecedents
"Affect associated with the antecedents" refers to the affective experiences of the subject after he/she identifies a need for privacy. According to past research, initial affect associated with a desire for privacy can be both negative (i.e., whether I am experiencing an overall negative affect while I am searching for privacy) or positive (i.e., whether I am experiencing an overall positive affect while I am searching for privacy). Negative affect involves the experiences characterized by a need for restoration, physically, emotionally, and cognitively, while positive affect involves a state characterized by a need for being productive and involved in something important in one's life. Of the total sample, 36.67% (N = 180) indicated the "desire to focus on my thoughts" as the primary reason to seek privacy while 23.33% indicated "tiredness" (i.e., "I most often require a period of privacy when I am tired").
Overall, both negative and positive affects associated with antecedents showed equal distribution of the data (Table 3).

After Effects Associated With Obtaining the Condition of Privacy
Most participants (75.00%; N = 180) evaluated the affective set associated with a condition of achieving privacy positively; conversely, only a small percentage of the sample (22.22%) stated that they felt worse after achieving a condition of privacy. These responses differed significantly, as indicated by a chi square of 51.571 with 1 df and a p-value of 0.001. "Ability to achieve privacy" refers to the subjects' assessment of their perceived ability to reach a condition of privacy when needed. Of the total sample (N = 180), 85.56% affirmed that they were able to pursue privacy "frequently" and 60% indicated they were able to pursue privacy only "occasionally". Smaller portions of the sample indicated that they could achieve privacy "rarely" (30%) or "always" (18.89%). Only 4.44% said that they were "never" able to achieve privacy.

Discussion
The present study aimed to explore the representation of privacy in an Italian sample and to investigate the importance of the two categories of functions of privacy (i.e., function of protection from threats, functions related to an achieved state of privacy) while considering the results of the spontaneous definition of privacy and those of the guided description of a daily experience of privacy. Specifically, participants were expected to make a positive use of privacy in their daily experience (Cole & Hall, 2010;Newell, 1998 According to the first aim of the current study, we wanted to explore the relevance of each of the two types of positive functions of privacy (i.e., the function of defense from threats and the functions related to the achieved state of privacy, such as the "system maintenance" function and the "system development" function) based on the participants' responses collected via open questions and pre-coded questions.
Overall, the findings that arose from the sample's spontaneous definitions showed that the subjects seem to attribute most relevance to the function of protection from threats compared to the two functions related to an achieved state of privacy. Specifically, the subjects' representations of privacy contained primarily references to both the defense from threats and the protection of personal information (Figure 1, Table 1). Figure 1 shows that four of the five clusters generated by the clusters analysis conducted in the current study, which are the first, the second, the forth, and the fifth cluster, dealt more or less explicitly with the aspects related to the defense against threats/protection of personal information (e.g., the fourth cluster collects strategies pertaining to protection, such as the behaviors of protecting the access to one's personal diary or to one's room). Similarly, the findings from the word association analysis (Table 1) showed the semantic closeness between the aspects concerning the protection of the most intimate aspects of life (e.g., personal data, intimate relationships information) and the concept of privacy. The sample's representations of privacy were built on its normative features, such as the management of personal information and the defensive mechanisms to protect one's intimacy from threats (e.g., "Privacy occurs when my personal space boundaries are respected", "I usually protect my personal information putting passwords everywhere"), as it is shown in the findings that arose from the content analysis (Appendix and Table 1). The conceptualization of privacy as a process aimed at protecting the most private information and defending the system from social threats, which arose from the participants' spontaneous accounts, reflects a traditional theoretical definition of privacy focused on the mechanisms used to protect the system from social threats (Altman, 1975;Hammitt, 2012). The "protection from social threats" nature of privacy is also shown in the guided exploration of the daily experience of privacy, where the stressful events that concern the interaction with other people ("social antecedents"), such as the condition of overcrowding, were most frequently reported as antecedents related to the need for a period of privacy, as indicated by the participants.
Considering the second function of privacy, the findings of the spontaneous definitions refer to the beneficial qualities of privacy related to an achieved state of privacy (i.e., function of maintenance, function of development).
This function of privacy has been mentioned less frequently compared to the function of protection from threats ( Figure 1, Appendix). These data confirms the first hypothesis (a), since the participants cited both functions of privacy (i.e., the function of protection and the functions related to the achieved state of privacy) in their spontaneous accounts. Moreover, the protection from threats is the most relevant concern that constitutes the great part of the participants' representation of privacy, and it may guide the most part of their privacy-related behaviors. Participants referred to the function associated with the achieved state of privacy mostly in their descriptions of the activities that one may carry out in private (Figure 1, Cluster 3). Therefore, these findings seem to suggest that satisfying the requirements of the protection of the system from threats (i.e., function of protection) is a prerequisite for experiencing the beneficial qualities provided by a period of privacy (i.e., maintenance of the system, development of the system). This proposed interpretation needs to be investigated in future studies.
Through the second hypothesis, (b) we expected that focusing on the two functions of privacy related to the achieved state of privacy (i.e., the function of maintenance and the function of development), the function of maintenance would be mentioned more frequently compared to the system development function because the aspects associated with the maintenance dimension are easier to identify in one's daily experience of privacy. The Positive Side of Privacy: Functions for Personal Well-Being Overall, the data shows that participants assigned an equal importance to both of the positive functions related to the achieved state of privacy, considering the spontaneous definitions as well as the guided exploration of the daily experience. It was found that subjects reported personal experiences related to the system maintenance function of privacy (e.g., "When I experience a period of privacy, then I feel regenerated", "I usually seek privacy when something stressful occurred and I need to recover") as well as to the system development function of privacy (e.g., "I feel privacy when I am alone in my own room. Once there, I can contemplate about my thoughts and put things in perspective", "Cultivate a friendship needs sharing one's privacy").
Furthermore, the outcomes of the pre-coded questions provided support for the high relevance ascribed to both beneficial functions of privacy related to an achieved state of privacy (i.e., system maintenance function, system development function). Further support was obtained through the equal distribution of the answers across negative and positive affects associated with the antecedent conditions of privacy (Table 3). In particular, we speculated that if a negative affective state, such as anxiety or anger, is experienced along with a need for privacy, then it is more likely that privacy would be required for its "systems maintenance functions" (e.g., in order to regulate one's emotions or to recover from overstimulation). Conversely, if a person feels positive affect, such as interest or curiosity in something, while he or she perceives a need for privacy, he or she would likely require privacy for its "systems development functions" (e.g., in order to commit to a creative task or to find concentration).
The results concerning the beneficial functions of privacy related to the achieved state of privacy can be also explained by the theoretical approach offered by the field of positive psychology (Kashdan, Biwas-Diener, & King, 2009;Kashdan & Steger, 2007). According to the subjective well-being perspective of positive psychology (Diener, 2000;Kahneman, Diener, & Schwarz, 1999), we found that an achieved period of privacy provides a positive experience, since it offers the opportunity for cognitive, emotional, and physical regeneration (Table 4).
Specifically, considering the spontaneous descriptions of the experience of privacy, subjects reported that they perceive privacy when they "feel in control over the environment", "perceive safety", as well as experience positive states, such as satisfaction after a reached period of privacy. This data is in line with previous findings (i.e., the concept of "therapeutic value to privacy", Newell, 1998, p. 367).
Moreover, the findings are also consistent with the psychological well-being perspective of positive psychology (Ryff & Singer, 1998, 2008, since individuals seek privacy while looking for psychological conditions that lead to self-actualization (Waterman, 1993) and personal growth (Keyes, 2002), such as self-monitoring, self-contemplation (Long, 2000;Long & Averill, 2003;Pedersen, 1997Pedersen, , 1999, and problem solving (Newell, 1994(Newell, , 1998. According to the abovementioned explanation, the primary motive to seek privacy is related to personal growth (i.e., systems development function of privacy), as the subjects indicated that privacy is sought most frequently to find creative solutions to problems and achieve some important life purposes (Table 2).
In addition, another unexpected result concerns the relevance of the two beneficial functions of privacy to the achieved state of privacy, as the participants mentioned the aspects related to personal growth (i.e., system development) more frequently than they did aspects related to maintenance of the system (i.e., system maintenance) [Chi square (df = 1) = 6.084; p = 0.01] (Table 2).
Overall, these findings disconfirmed the second hypothesis (b), which proposed that the system maintenance function of privacy would be mentioned more frequently compared to the system development function, supporting previous findings (Newell, 1994 both for its maintenance function and for its system development it can support, even if it is more frequently required to accomplish personal growth processes, as indicated by the sample's daily experiences.
According to the second aim (2) regarding the experience of the positive functions of privacy related to the type of environment (digital vs. physical environment), privacy seems to be most frequently violated in the digital environment where the negative consequences are intensified by the perception of low control over who is managing one's information and by the way in which personal information is managed according with the structural features of the environment. In particular, the interactions provided by the new media seem to facilitate the intrusion into the private space and to enhance the perception of the loss of control (Figure 1). Considering these results, it may be possible to state that subjects viewed the function of one's protection against threats as a defense process that is highly related to this type of environment. Conversely, references to the beneficial qualities of privacy, reflecting systems development function and systems maintenance function, were related to the physical environment, as reported by the Italian sample ( Figure 1). In particular, the material features of the environment, such as the physical space that provides physical barriers that are easy to use to exercise control over the access to one's space and information (e.g., " […] when I spend time alone in my room and I can decide who to let in"), were mostly associated with positive experiences. The benefits provided by a state of privacy achieved are easily recognized ( Figure 1). These findings confirm the third hypothesis of the current study and support the existing literature on the topic (Cole & Hall, 2010;Hammitt, 2012;Palen & Dourish, 2003;Tu, 2002b) that identified the function of privacy related to system protection from threats in digital context and reported the benefits of a privacy experience in the physical environments.
Moreover, the data is in line with the abovementioned idea that participants seem to be mostly concerned with the control over the access to their personal information, and they recognize the beneficial qualities of privacy while they experience it. However, when it is difficult to exercise control due to the environmental features of the setting of the interaction, such as in digital environments (vs. physical environments), they focus on the strategies to assure their protection from threats rather than to identify benefits of privacy.
These findings are also consistent with the idea that the function of protection of privacy is a precondition for achieving privacy and thus its beneficial qualities for well-being.
Finally, the role of the environment in shaping the experience of privacy provides the possibility to confirm the conception of privacy as a socio-environmental construct, which depends on both personal and environmental factors as well as on their interaction (Pedersen 1997(Pedersen , 1999.

Conclusion
The present study considers privacy as a supportive condition for some psychological processes involved in human well-being, such as increasing the sense of control over the environment (Altman, 1975; This study has some limitations. First shortcoming is related to the self-reported method we chose in order to satisfy the purposes of the study, such as the exploration of the benefits of privacy in the subjects' daily experience. Indeed, it would be useful to integrate the obtained data with more objective types of measures, such as observational measures or cognitive measures of performance in specific psychological processes (e.g., creative thinking), to estimate the enhancement of these processes after an achieved period of privacy.
A further problem is related to the instrument that we used to collect the data about the guided exploration of the subjects' daily experience of privacy. We considered an instrument taken from past research (Newell, 1998) as the basis of our investigation. Two main problems related to the use of this instrument need to be considered.
First, we did not investigate the defensive function of privacy. This choice was justified by the fact that the defensive function of privacy has been broadly investigated in the past. Thus, it would be more interesting to investigate the second type of function of privacy, such as that concerned with the benefits related to an achieved state of privacy, since it has attracted only little interest so far. Nevertheless, the present work could be expanded by including questions about the defensive function of privacy. Second, some suggestions for the improvement of the answer categories used in the instrument arose from the data collected though the free exploration of the daily experience of privacy. For instance, the answer categories could incorporate the effects related to an experienced state of privacy. This information could be integrated in the next version of the pre-coded instrument.
However, the current work contributes to the existing literature on the psychological experience of privacy.
First, the study used the quali-quantitative analysis, which proved to be helpful for investigating more deeply about the social representation of privacy and the use of privacy in daily life. It provides data that offer a thorough and comprehensive overview of the subjects' experience of privacy. Thus, the findings from this work could be used to inform further studies on the functions and process of privacy. For instance, we propose a theory of the process of privacy based on its effects on well-being. It would be interesting to verify the proposed theory in future research.
Second, the study focused on the unusual facets of the construct of privacy. Privacy can be considered a double psychological concept that has received much attention largely because of its protective function (Altman, 1977;Boyle, Neustaedter, & Greenberg, 2009;Palen & Dourish, 2003;Röcker & Feith, 2009) while its unusual side related to the benefits of an experienced state of privacy has been neglected (Newell, 1994). We believe that the beneficial features of privacy are worthy of studying, as they can have remarkable practical implications, for instance, by increasing the attention to conditions facilitating a person-environment interaction that would support privacy in critical contexts, such as schools, workplaces, and health-care environments. We also believe that positive psychology can offer the theoretical and practical instrument to investigate privacy as a positive experience.
In conclusion, some practical indications arise from the current work. Overall, our findings seem to suggest that people are mostly concerned with the protection of privacy (i.e., function of defense of the system) rather than with well-being related to an experience of privacy (i.e., function of maintenance of the system, function of development of the system). Thus, future research should investigate the ways in which the control over the social interaction could be assured, especially in specific kind of environments where it might be difficult to manage access to one's personal information, such as the digital environments, in order to enhance the benefits offered by an achieved condition of privacy.
