Inversion Impairs Expert Budgerigar Identity Recognition: A Face-Like Effect for a Nonface Object of Expertise. | LitMetric

AI Article Synopsis

  • The face-inversion effect refers to the difficulty in recognizing inverted faces compared to other objects, which is attributed to our special way of processing faces holistically.
  • Expert dog judges experience similar recognition issues with inverted dog images as face experts do with faces, indicating that this holistic processing may apply to other objects that experts are familiar with.
  • A study comparing expert and novice recognition of inverted budgerigar birds and faces found that while novices struggled with inverted faces, experts had recognition deficits for both inverted faces and budgerigars, suggesting that the face-inversion effect is linked to the expert recognition of similar objects.

Article Abstract

The face-inversion effect is the finding that picture-plane inversion disproportionately impairs face recognition compared to object recognition and is now attributed to greater orientation-sensitivity of holistic processing for faces but not common objects. Yet, expert dog judges have showed similar recognition deficits for inverted dogs and inverted faces, suggesting that holistic processing is not specific to faces but to the expert recognition of perceptually similar objects. Although processing changes in expert object recognition have since been extensively documented, no other studies have observed the distinct recognition deficits for inverted objects-of-expertise that people as face experts show for faces. However, few studies have examined experts who recognize individual objects similar to how people recognize individual faces. Here we tested experts who recognize individual budgerigar birds. The effect of inversion on viewpoint-invariant budgerigar and face recognition was compared for experts and novices. Consistent with the face-inversion effect, novices showed recognition deficits for inverted faces but not for inverted budgerigars. By contrast, experts showed equal recognition deficits for inverted faces and budgerigars. The results are consistent with the hypothesis that processes underlying the face-inversion effect are specific to the expert individuation of perceptually similar objects.
