Infants' representations of michottean triggering events

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Perception

Background:

• Adults and infants can distinguish physical launching events from those violating Newtonian elastic collision principles.
• Key constraints include relative speeds and collision angles, which infants under 9 months recognize.

Purpose of the Study:

• To investigate whether 7-8-month-old infants perceive Michottean triggering events as causal.
• To explore infant sensitivity to agent-patient role reversals in triggering events.

Main Methods:

• Experiment 1: Infants viewed canonical launching events versus those with violated speed or angle constraints (triggering events).
• Experiments 2 & 3: Infants' responses to agent-patient role reversals in triggering events were assessed.

Main Results:

• Infants distinguished between physically possible and impossible launching events (Experiment 1).
• Infants did not show sensitivity to agent-patient role reversals in triggering events, a key indicator of causal understanding.
• This suggests infants may not represent all triggering events as fully causal.

Conclusions:

• Young infants possess multiple, independent event schemas for causal understanding.
• Further research should explore various event schemas beyond launching events to understand the origins of infant causal cognition.
