Detecting the causal relations among environmental events is an import
ant facet of learning. Certain variables have been identified which in
fluence both human causal attribution and animal learning: temporal pr
iority, temporal and spatial contiguity, covariation and contingency,
and prior experience. Recent research has continued to find distinct c
ommonalities between the influence these variables have in the two dom
ains, supporting a neo-Humean analysis of the origins of personal caus
al 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 examina
tion of animal learning research motivates further extensions of the a
nalogy. Researchers are encouraged to study real-time causal attributi
ons, to study additional methodological analogies to conditioning para
digms, and to develop rich learning accounts of the acquisition of cau
sal theories.
