Is there a criterion in criterial learning? Insights from studying feedback delays

Area of Science:

• Cognitive Psychology
• Computational Neuroscience
• Learning Sciences

Background:

• The concept of a response criterion is fundamental in psychology but its cognitive and neural basis is unclear.
• Two main theories exist: comparing stimuli to a stored criterion versus associating responses with stimuli.

Purpose of the Study:

• To empirically test and differentiate between two prominent interpretations of criterial learning.
• To investigate the role of feedback delay and intertrial interval duration in criterial learning.

Main Methods:

• Conducted two experiments using a one-dimensional category-learning task.
• Employed extensive computational modeling to analyze behavioral data.
• Contrasted the effects of feedback delays versus intertrial interval durations on learning.

Main Results:

• Empirical data indicated that human criterial learning is sensitive to feedback delay.
• Learning was not affected by changes in the intertrial interval duration.
• Computational modeling supported a stimulus-response learning account.

Conclusions:

• Results are incompatible with traditional stored-criterion models unless they incorporate feedback delay sensitivity.
• Findings suggest criterial learning involves stimulus-response associations rather than a fixed stored criterion.
• The study advances understanding of the mechanisms underlying decision-making and learning.
