People often overestimate event contingencies due to probability biases. While dual-process models were proposed, this review finds scarce and inconclusive evidence supporting them for biased contingency detection.
Area of Science:
- Cognitive Psychology
- Learning and Memory
Background:
- Causal and contingency learning research demonstrates probability-based biases in estimating event relationships.
- Simple single-process models traditionally explain these biases.
- Recent findings suggest dissociations across dependent variables, leading to dual-process model proposals.
Purpose of the Study:
- To review evidence supporting dual-process models in contingency learning.
- To identify shortcomings and limitations in the existing literature on these dissociations.
Main Methods:
- Literature review of studies investigating dissociations in contingency learning biases.
- Critical analysis of the replicability, generalizability, and methodological artifacts of reported dissociations.
Main Results:
- Some reported dissociations supporting dual-process models are difficult to replicate or generalize.
- Other dissociations may be attributable to methodological artifacts rather than distinct cognitive processes.
Conclusions:
- The evidence for dual-process models explaining biased contingency detection is currently scarce and inconclusive.
- Further rigorous research is needed to validate or refute the dual-process account.
