Face recognition (FR) involves feature and holistic processing. Autistic children show deficits in holistic facial arrangement recognition, potentially due to altered neural pathways from periphery to cortex.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Cognitive Science

Background:

  • Face recognition (FR) is crucial for social interaction.
  • FR differs from object recognition, relying on specific facial features.
  • Autism Spectrum Disorder (ASD) is characterized by social deficits, possibly linked to impaired facial processing.

Purpose of the Study:

  • To review literature on face recognition mechanisms.
  • To explore the developmental trajectory of face recognition in infants.
  • To investigate potential alterations in face recognition pathways in autistic individuals.

Main Methods:

  • Literature survey on face recognition mechanisms.
  • Analysis of developmental aspects of face processing in infants and autistic children.

  • Examination of feature-based vs. holistic processing models.

    • Main Results:

    • Two primary FR mechanisms identified: feature-based and holistic (overall image and arrangement).
    • Infants show early preference for holistic facial aspects.
    • Autistic children exhibit erratic visual development and a feature-based processing style, similar to newborns.

    Conclusions:

    • FR mechanisms develop early in infancy.
    • Intact facial arrangement recognition pathways are vital for social interaction.
    • Altered peripheral and cortical pathways may underlie impaired facial arrangement recognition in autism.
