Judging causal priority

Children with autism spectrum disorder have an exceptional explanatory drive

An "explanatory drive" motivates children to explain ambiguity. Individuals with autism spectrum disorders are interested in how systems work, but it is unknown whether they have an explanatory drive. We presented children with and without autism spectrum disorder unsolvable problems in a physical and in a social context and evaluated problem-solving and explanation-seeking responses. In the physical context (but not the social context), the children with autism spectrum disorder showed a stronger explanatory drive than controls. Importantly, the number of explanatory behaviors made by children with autism spectrum disorder in the social context was independent of social and communicative impairments. Children with autism spectrum disorder did not show an exceptional explanatory drive in the social domain. These results suggest that children with autism spectrum disorder have an explanatory drive and that the explanatory drive may be domain specific.

On the origin of personal causal theories

Detecting the causal relations among environmental events is an important facet of learning. Certain variables have been identified which influence both human causal attribution and animal learning: temporal priority, temporal and spatial contiguity, covariation and contingency, and prior experience. Recent research has continued to find distinct commonalities between the influence these variables have in the two domains, supporting a neo-Humean analysis of the origins of personal causal theories. The cues to causality determine which event relationships will be judged as causal; personal causal theories emerge as a result of these judgments and in turn affect future attributions. An examination of animal learning research motivates further extensions of the analogy. Researchers are encouraged to study real-time causal attributions, to study additional methodological analogies to conditioning paradigms, and to develop rich learning accounts of the acquisition of causal theories.
