An initial but receding altercentric bias in preverbal infants' memory

Area of Science:

• Cognitive Development
• Evolutionary Psychology
• Infant Perception

Background:

• Infant attention is crucial for learning.
• Evolutionary changes in carrying practices may impact infant attention.
• A novel theory proposes an altercentric bias in early human infant cognition.

Purpose of the Study:

• To investigate the altercentric bias in human infants.
• To determine if infants prioritize encoding events targeted by others' attention.
• To examine memory recall when perspectives conflict.

Main Methods:

• Tested 8- and 12-month-old infants.
• Used a conflicting perspective task involving an object's location.
• Assessed memory recall based on co-witnessed locations.

Main Results:

• 8-month-olds expected objects to be where an observing agent saw them.
• 12-month-olds did not show this bias.
• Infants prioritized encoding events attended to by others, leading to potential memory errors.

Conclusions:

• Infants exhibit an altercentric bias in the first year of life.
• This bias facilitates learning during a period of motor immaturity.
• The bias disappears by 12 months, indicating a transient but important cognitive feature.
