Reading text with and without diacritics alters brain activation: The case of Arabic

Current Psychology Aims and scope Submit manuscript

Abstract

Diacritics in Arabic are optional orthographic symbols used to alter the pronunciation of a letter or distinguish between words of similar spellings, which may add or subtract complexity by imposing additional loads on the individual’s information-processing system. In this study, we explored how reading Arabic text with and without diacritical signs (known as ḥarakāt) can influence readers’ brain activation. An electroencephalogram (EEG) recording of 18 subjects was used in this study to assess the differences in brain activation while reading in two reading conditions (with and without ḥarakāt). The results showed that ḥarakāt had a significant impact on the cognitive responses of subjects as exemplified by differences in cortical activity between the conditions. Our results imply promising results in the application of reading skills where diacritical marks may play a key role in increasing the level of attention an individual pays to text, thus improving information-processing accuracy.
