A dissociation between causal judgement and the ease with which a cause is categorized with its effect

Area of Science:

• Cognitive Psychology
• Human Causal Learning

Background:

• The associative view posits causal learning stems from activating mental representations via associations, akin to animal conditioning.
• Human causal learning research often employs tasks to understand how individuals attribute causation.

Purpose of the Study:

• To test the associative theory of human causal learning using a conditioned inhibition design.
• To investigate the relationship between causal judgments and associative strengths in a categorization task.

Main Methods:

• Participants engaged in a task where herbal remedies (X, Y) were trained to prevent allergic reactions (O1, O2) in a conditioned inhibition design.
• Causal judgments were assessed using a summation test, followed by a categorization task to measure associative strengths.

Main Results:

• Causal judgment tests revealed inhibitory relationships between remedies and reactions (X-O1, Y-O2).
• Categorization tasks showed excitatory associations (X-O1, Y-O2), contradicting the inhibitory findings.
• The pattern of excitation and inhibition depended on trial interleaving, challenging standard associative activation theories.

Conclusions:

• Results challenge the direct application of associative activation theories to causal judgment.
• Inhibition in causal judgment tasks may reflect inferential reasoning, not just associative strength.
• Inferential reasoning relies partly on the cue's ability to excite outcome representations, as shown in categorization.
