Evidence for a distinction between judged and perceived causality
1University of California, San Diego.
Summary
Michotte's launch event, where one object appears to cause another's motion, was tested. Competing cues like color changes did not alter perceived causality, suggesting direct causal perception is robust.
Area of Science:
- Cognitive Psychology
- Perception Science
Background:
- Michotte's launch event describes the perception of causality between moving objects.
- Investigating factors influencing the perception of causality in visual events.
Purpose of the Study:
- To determine if learning alternative predictive relationships affects causal impressions of launch events.
- To explore the distinction between perceived and judged causality.
Main Methods:
- Two experiments presented launch events with varying temporal contiguity and competing predictive cues (object color change).
- Participants rated perceived causality in single events and judged the necessity of collisions in overall event sets.
Main Results:
- Perceived causality ratings in Experiment 1 were unaffected by a reliable color-change predictor.
- Experiment 2 revealed a dissociation: perceived causality showed a contiguity effect, while judged necessity showed both contingency and contiguity effects.
Conclusions:
- Findings support a distinction between direct perceived causality and explicitly judged causality.
- Results are discussed in relation to Michotte's theory of direct causal perception.
