The Face Recognition Test, developed by Benton and colleagues, is a neuropsychological test that assesses face recognition impairment that occurs in cases of lesions of the posterior parts of the right hemisphere. The Face Recognition Test consists of a 22-page A4 sized book with pictures of faces and a form to record the answers. The reliability of the test was checked by applying "test-retest" on 48 normal subjects and "split-half reliability" on the data of the whole group.
To assess the predictive validity of the test, the test scores of 30 patients with posterior cerebral artery infarction (half with right and half with left hemisphere localization) were compared with the control group. FINDINGS: The results of the study showed that there was a negative correlation between age and education level of the subjects and test performance. The reliability level of the test was determined as r=.78 for the short form and r=.84 for the long form as a result of the retest technique. When the test performance of patients with right posterior cerebral artery infarction and normal subjects were compared, the test scores of normal subjects were significantly higher than the scores of the patient group (p<0.05).
The Benton Face Recognition Test (BFRT) is another test used by neuropsychologists to assess face recognition skills. Individuals are given a target face over six test faces and asked to identify which test face matches the target face. Since many people with prosopagnosia use hair and clothing cues to recognize faces, the pictures are cropped to exclude hair and clothing. Both male and female faces are used during the test. For the first six items, only one test face matches the target face: for the next seven items, three of the test faces match the target faces and the poses are different. A study by Duchaine and Nakayama questioning the reliability of the BFRT showed that the mean score for 11 self-reported prosopagnosics was within the normal range.
The Benton Face Recognition Test measures the recognition of unfamiliar human face photographs in individuals aged 16-74 years. The Benton Face Recognition Test is administered to patients with prosopagnosia. In the face recognition test, the following tasks are performed in items consisting of a target photograph taken from the front and six options:
1. find the same target photograph among the choices,
2. match the target photo with three photos of the same person from different angles,
3. matching the target photo with one taken under different lighting conditions (reduced by 1/4, 2/4, 3/4 compared to normal lighting).
Scoring is done as the number of correct responses. Scores represent the functionality of the posterior of the non-dominant hemisphere, specifically the angular gyrus and fusiform gyrus.
