Their study sought to find out more about the disorder in its congenital aspect. The researchers specifically wanted to know whether eye-movement based memory effect can stipulate evidence in congenital prosopagnosia. The behavioural indicator is a reprocessing result in face recognition. This means that when viewing a familiar object, the eye fixates less. The eye’s appraisals also occur in fewer areas. Formerly, prosopagnosia was commonly regarded as quite rare. However, recent experts have asserted that some are born with this impairment, thus, the term congenital prosopagnosia.

This spectrum is characterized by having difficulties in perceiving not only faces but objects and visual scenes as well. The research consisted of two experiments. The first one aimed to duplicate the face reprocessing effect in two age groups (young adults and old adults). The 19 participants had normal vision acuities. They were made to view 40 different stimuli on the screen. Each face was presented for 5 seconds. Half of the materials were familiar. If a participant would perceive the stimulus as “known”, he would press the right button and the left if it were otherwise.

Their respective reaction times were then recorded. The respondents’ retinal focus were assessed and calibrated. . Since childhood, he had difficulties in identifying faces and is presently having trouble in recognizing his children’s early years’ photos. In addition to the procedure done in the first experiment, a confidence rating regarding the respondent’s answers were employed. The results showed that all of the unfamiliar faces were correctly identified. However, only 85% of the “known” photos were appropriately recognized.

The rates of his confidence level regarding his responses were slightly higher for unfamiliar stimuli at 3.2 out of 5. There was a significant difference in his reaction time at 0.001 with the F tabulated value 12. 702 (1, 35). His reactions were faster when it comes to unfamiliar faces. The experiments then conclude that congenital prosopagnosia may be evaluated using behavioural indicators. The second article is done by Righart and de Gelder. Their paper is entitled, Impaired Face and Body Perception in Developmental Prosopagnosia (2007).

Their paper aimed to find out if the disorder also involves the inability to recognize the people’s bodies. Brain scanning techniques have shown certain brain areas that get activated when the individual tries to recognize faces and objects. Currently, cutting edge technology has made it possible to assess parts in the brain when recognizing bodies. The methodology required four participants. Their particular phases of perception were evaluated and recorded. Firstly, how the respondents detected objects, faces, and bodies in the initial stage was substantiated.

This was done by judging various kinds of incident-related possibilities to standardized and disorganized pictures. Three among the four individuals with developmental prosopagnosia had results that signified incorrect stimuli
