Connecting developmental trajectories: biases in face processing from infancy to adulthood.

Area of Science:

• Developmental Psychology
• Cognitive Neuroscience
• Human Perception

Background:

• Face recognition abilities develop across the lifespan, but the precise trajectory remains unclear.
• Existing theoretical frameworks struggle to explain diverse developmental changes in face processing biases.
• A functionalist perspective, considering age-appropriate tasks, offers a novel approach to understanding this development.

Purpose of the Study:

• To explore the developmental trajectory of face recognition from infancy to adulthood.
• To propose a functionalist approach integrating age-specific developmental tasks and goals.
• To review changes in face processing biases (species, race, age, gender) across development.

Main Methods:

• Literature review focusing on developmental changes in face processing biases.
• Analysis of existing theoretical frameworks for face recognition development.
• Identification of age-specific developmental tasks influencing face perception.

Main Results:

• No single existing theory adequately explains the varied developmental trajectories and plasticity of face processing biases.
• Infant and adolescent-specific tasks are predicted to significantly influence how individuals process facial information.
• Developmental tasks shape the nature and content of information extracted from faces at different life stages.

Conclusions:

• A functionalist approach is crucial for a comprehensive understanding of face recognition development.
• This approach can illuminate the impact of early experiences and the quality/range of experiences on shaping face processing.
• Future research should investigate age of acquisition effects and critical experiences in face perception development.
