Second-order conditioning in human predictive judgements when there is little time to think

Area of Science:

• Cognitive Psychology
• Learning and Memory

Background:

• Associative learning theories predict second-order conditioning in human predictive judgments.
• Second-order conditioning involves learning associations between stimuli and outcomes.

Purpose of the Study:

• To investigate the role of pacing in second-order conditioning within human predictive judgments.
• To examine how temporal constraints influence the acquisition of associative and inhibitory learning.

Main Methods:

• Two experiments were conducted using paced and unpaced trial structures.
• Participants made predictions on trials involving conditioned stimuli (P, X, T) and outcomes (+/-).
• Inhibitory learning was assessed using a summation test (TX vs. TM).

Main Results:

• Second-order conditioning effects were observed for cue X exclusively under paced conditions.
• Inhibitory learning was evident in the unpaced group via the summation test.
• Pacing appeared to facilitate successive associative learning while potentially hindering inhibitory learning.

Conclusions:

• Pacing may differentially affect the learning of successive versus simultaneous associations.
• Time constraints imposed by pacing might interfere with the inferential processes necessary for inhibitory learning.
• Findings suggest that temporal factors are critical in shaping associative and inhibitory learning in humans.
