Studying associative learning without solving learning equations

Publication date: August 2018Source: Journal of Mathematical Psychology, Volume 85Author(s): Stefano GhirlandaAbstractI introduce a simple mathematical method to calculate the associative strengths of stimuli in many models of associative learning, without solving the models’ learning equations and without simulating the learning process. The method applies to many models, including the Rescorla and Wagner (1972) model, the replaced elements model of Brandon et al. (2000), and Pearce’s (1987) configural model. I illustrate the method by calculating the predictions of these three models in summation and blocking experiments, allowing for a degree of similarity between the training stimuli as well as for the effects of contextual stimuli. The method clarifies the models’ predictions and suggests new empirical tests.
