Summary
Young children show experience effects in face recognition, with inversion and other-race effects present by age 3. Face orientation and morphology constrain early face processing.
Area of Science:
- Developmental psychology
- Cognitive neuroscience
- Perceptual development
Background:
- Face recognition in adults is influenced by experience effects like inversion and the other-race effect.
- Understanding the developmental trajectory of these face processing mechanisms in children is crucial.
Purpose of the Study:
- To investigate the presence and developmental nature of face recognition effects in early childhood.
- To determine when inversion and other-race effects emerge in children's face perception.
Main Methods:
- Tested 64 Caucasian children aged 3–5 years on recognizing upright and inverted Caucasian and Asian faces.
- Employed a forced-choice recognition procedure to assess performance.
- Analyzed recognition accuracy in relation to face orientation and ethnicity.
Main Results:
- Overall face recognition performance improved with age in the 3–5 year old group.
- An interaction between inversion and other-race effects was observed, consistent across ages 3–5.
- The inversion effect was larger for native (Caucasian) faces than non-native (Asian) faces.
- Upright native faces were recognized better than upright non-native faces.
Conclusions:
- Face orientation and morphology significantly constrain face processing in 3- to 5-year-old children.
- The initial 3 years of brain-environment interaction are sufficient to establish a foundational face-processing system.
