It clicks when it is rolled and it squeaks when it is squeezed: what 10-month-old infants learn about object function

Area of Science:

• Cognitive Development
• Infant Learning
• Object Perception

Background:

• Object function is crucial in cognitive development studies.
• Limited understanding exists on how infants acquire knowledge about object function.
• Sound-associated object functions are under-explored in infant research.

Purpose of the Study:

• To investigate what 10-month-old infants learn about object functions involving sounds.
• To examine infants' ability to associate actions, sounds, and object appearances.
• To understand the developmental trajectory of learning object affordances.

Main Methods:

• Five experiments were conducted with 80 ten-month-old infants.
• Habituation paradigms were used to assess infant learning.
• Infants were exposed to objects producing sounds through various actions.

Main Results:

• Infants learned actions and sounds associated with single or multiple objects performing a function.
• No evidence was found for infants learning action-sound or appearance-sound relations.
• Infants demonstrated learning of appearance-action relations.

Conclusions:

• Infants learn specific components of object function, particularly action-sound associations.
• Learning object function involves distinct developmental stages and associative abilities.
• Findings contribute to understanding early causal reasoning and object exploration in infants.
