This study reports on a patient with severe prosopagnosia who could recognize sheep but not faces. Findings suggest prosopagnosia can be a face-specific disorder.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Neurology

Background:

  • Prosopagnosia is a neurological disorder characterized by the inability to recognize familiar faces.
  • This case study examines a patient with severe prosopagnosia following a stroke.

Observation:

  • The patient, WJ, developed a severe deficit in facial recognition after a stroke.
  • He later acquired a flock of sheep and demonstrated an ability to recognize and name individual animals.

Findings:

  • WJ's performance on recognition memory and paired-associate learning tasks was significantly better for sheep than for human faces.
  • This suggests a dissociation in recognition abilities, with preserved non-face object recognition.

Implications:

  • The findings support the hypothesis that prosopagnosia can be a face-specific disorder.
  • This has implications for understanding the neural basis of face recognition and object recognition.
