What Is the Face Inversion Effect and How Does It Relate to Prosopagnosia?

💡 The Answer

• Typically people recognize upright faces much better than inverted faces.
• This inversion effect is reduced in prosopagnosia, indicating holistic processing deficits.
• Healthy brains process faces holistically; inversion disrupts this ability.
• Prosopagnosics may process faces part-by-part, similarly to objects.
