Face processing
-
Own race effect - Herzman et al, 2022
-
Due to: perceptual expertise, social and cultural familiarity and cognitive biases.
Own-race faces are encoded more elaboratively - learning many features of the face or the whole face. Whereas other race faces are encoded using only select features - not the whole face.

Importance of ambient images - smiling (Sutherland et al, 2015)
1st impressions - Big 5 vs dominance, approachability and youthfulness/attractiveness
Approachability: openness, extraversion, emotional stability and agreeableness. Related to emotional expression.
Dominance and approachability: conscientiousness. Cues of facial maturity, masculinity and strength.
When forming impressions of strangers from highly varying naturalistic photos, perceivers mainly seem to rely on broad facial cues to approachability e.g. smiling.
Ambient facial images and autism (Gedhu et al, 2020)
Ambient facial images depict individuals from a variety of viewing angles - range of poses and expressions, using different lighting.
Exposure to AFI is thought to help observers form robust representations of the individuals depicted.

Familiar vs unfamiliar faces (Friewald et al, 2016)
More research relies on using unfamiliar faces as they are ideal to isolate the contribution of the visual system.
Familiar faces are associated with more semantic, social and emotional info = enhanced recognition.
Recognition of familiar faces is robust even in different variations in the image of a given person.

Prosopagnosia (Pinel & Barnes, 2021)
Failure to recognise faces, not due to a sensory deficit, or verbal or intellectual impairment.
-
can be developmental or acquired through brain injury. Associated with injury to extrastriate visual cortex perhaps including the fusiform face area (Bears et al, 2016). Also injury to the ventral occipital lobe, anterior temporal lobe in right hemisphere (Freiwald et al, 2016)
Faces (Gilhooly et al, 2022)
- humans are tuned to recognise familiar faces even under adverse conditions.
- recognition of unfamiliar faces can be surprisingly poor
