A three-component model of relational responding in the transposition paradigm

Area of Science:

• Animal behavior
• Cognitive psychology
• Comparative psychology

Background:

• Transposition behavior is a fundamental concept in learning and memory.
• Understanding the factors influencing choice behavior in animals is crucial for cognitive research.

Purpose of the Study:

• To introduce and validate a novel computational model for transposition behavior.
• To identify and quantify the predictors of transposition behavior in pigeons.
• To assess the relative contributions of reinforcement history and stimulus properties to choice behavior.

Main Methods:

• A new model incorporating generalized associative strength (g), relational disparity (r), and familiarity (f) was developed.
• Experiments were conducted with pigeons using circle diameter and speed of motion as sensory dimensions.
• The model was evaluated against behavioral data from various training and testing pair configurations.

Main Results:

• Generalized associative strength (g) consistently predicted behavior, independent of training set size.
• Relational disparity (r) significantly increased in influence with more training pairs.
• Familiarity (f) impacted behavior differently based on the stimulus domain, being significant for circle area but not speed of motion.

Conclusions:

• Pigeon transposition behavior is influenced by both reinforcement history (g) and the relationship between stimuli (r, f).
• The proposed model offers a quantitative framework for analyzing choice behavior in animal learning.
• The findings highlight the domain-specific nature of stimulus familiarity in decision-making processes.
