Covariation, Causality, and Language

Abstract

Implicit verb causality refers to the phenomenon that even minimal descriptions of interpersonal events (e.g., A dominates B, A amuses B) elicit causal attributions. Two experiments investigated whether children of different age groups are able to (a) perceive the causality implicit in interpersonal verbs and (b) to detect patterns of cause-effect covariation (consensus and distinctiveness) presumably mediating the verb causality effect. Experiment 1 found that 5-year-old children detect the causal structure inherent in verbs describing interpersonal events and are able to indicate corresponding covariation patterns. Experiment 2 replicated these findings for 3-year-old children using a more sensitive method for assessing causal and covariation beliefs. Statistical mediation analyses supported the hypothesis that the verb causality effect is mediated by implicit beliefs about cause-effect covariation. Taken together, the results provide support for a covariation-based explanation of the verb causality effect.
