Are preventive and generative causal reasoning symmetrical? Extinction and competition

Area of Science:

• Cognitive Psychology
• Learning and Memory
• Causal Inference

Background:

• Investigating the symmetry of preventive (inhibitory) and generative (excitatory) reasoning is crucial for understanding causal learning.
• Previous models often treat excitation and inhibition asymmetrically, necessitating empirical validation.

Purpose of the Study:

• To compare the acquisition and extinction of excitatory and inhibitory causal cues under controlled conditions.
• To test the predictions of inferential reasoning accounts regarding variable outcomes in causal learning.

Main Methods:

• Experiment 1: Employed a novel extinction procedure within a blocking design to compare the loss of inhibitory versus excitatory cue properties.
• Experiment 2: Investigated the blocking effects for both excitatory and inhibitory causes.
• Utilized a variable outcome to assess predictions of inferential reasoning models.

Main Results:

• Inhibitory cues were more susceptible to extinction than excitatory cues using the novel extinction procedure.
• Blocking effects were found to be similar for both excitatory and inhibitory causes.
• Acquisition of excitation and inhibition appears symmetrical, but extinction shows asymmetry.

Conclusions:

• Causal learning involves both symmetrical acquisition and asymmetrical extinction of excitatory and inhibitory cues.
• The findings challenge purely symmetrical models of causal reasoning and support accounts that differentiate inhibitory processes.
• Further research is needed to refine models of causal inference considering these asymmetries.
