Abstract

This paper derives the constraints on a set of channels that would be consistent with the results of several experiments on the temporal properties of the visual system, and it describes a specific set of channels that meet these constraints. Data on simultaneous detection and discrimination require a minimum of three channels. Temporal frequency discrimination at and above threshold constrain the bandwidths and locations of the channels. The shape of the temporal modulation sensitivity function constrains their sensitivities. The functions that meet these constraints are similar to those derived from masking data, and they can account for data on flicker matching, notch losses in modulation sensitivity, and changes of perceived temporal frequency with changes of modulation depth.

      Temporal processing in the human visual system frequently is studied using detection thresholds (Kelly, 1961; Mandler & Makous, 1984; Smith, 1971; Lee, Pokorny, Smith, Martin, & Valberg, 1990; Cass & Alais, 2006). The temporal contrast sensitivity function, which characterizes human sensitivity to different temporal frequencies, is believed to result from multiple underlying temporal mechanisms (Cass & Alais, 2006; Mandler & Makous, 1984). The current study shows this is also the case for the influence of temporally varying surrounding context.

      Citation Excerpt :

      Unlike spatial contrast adaptation, temporal contrast adaptation does not only occur at stimulus frequencies that are close to the adapting frequency (Smith, 1971). Instead two (Cass & Alais, 2006) and possibly three (Mandler & Makous, 1984) temporal frequency channels are proposed. A low temporal frequency channel (up to about 4 Hz) probably has a cortical origin because cortical neurons respond only at these temporal frequencies.

      First, a noisy visual motion signal could be attenuated in magnitude by some kind of gain control, leading to weaker pursuit acceleration (Stocker and Simoncelli, 2006). Second, our low-level motion test (relatively high in temporal frequency at 11 Hz) could rely upon a high temporal frequency mechanism important for robust pursuit acceleration (Mandler and Makous, 1984). Recent functional magnetic resonance imaging, electrophysiological, and lesion studies suggest that human IPL (inferior parietal lobe), monkey LIP (lateral intraparietal area) and area 7a, and other parietal areas may play a role in high-level motion processing (Battelli et al., 2001; Claeys et al., 2003; Williams et al., 2003; Merchant et al., 2005).
