Question

Quizplus · Accepted Answer

The evidence for individuals with face blindness being able to unconsciously perceive faces comes from studies showing that they have physiological responses to familiar faces, such as increased skin conductance and changes in heart rate, that they do not have for strangers. This suggests that they are recognizing the faces on some level, even if they are not consciously aware of it. Option A is incorrect because guessing names from pictures without knowing why does not necessarily indicate unconscious perception of faces. Option B is incorrect because individuals who believe that familiar faces are imposters are experiencing a specific type of face blindness called Capgras syndrome, which does not necessarily indicate unconscious perception of faces either. Option D is incorrect because making up names for faces does not necessarily indicate any type of face recognition or perception.
