In addition, the new version permits specifying probe trials among standard trials and extracting their values. This paper introduces a compound-based simulator of the Temporal Difference model that implements new algorithms to work with contexts, stimulus compounds, configural cues, and different time-steps.

In addition, the simulator allows the input of universal trial based designs and computes and displays numerical and graphical outputs per trial and per stimulus component, as well as simulated responses. Simulated results can be directly exported to a data processor spreadsheet. In the present special issue, the performance of current computational models of classical conditioning was evaluated under three requirements: 1 Models were to be tested against a list of previously agreed-upon phenomena; 2 the parameters were fixed across simulations; and 3 the simulations used to test the models had to be made available.

These requirements resulted in three major products: a a list of fundamental classical-conditioning results for which there is a consensus about their reliability; b the necessary information to evaluate each of the models on the basis of its ordinal successes in accounting for the experimental data; and c a repository of computational models ready to generate simulations. We believe that the contents of this issue represent the state of the art in computational modeling of classical conditioning and provide a way to find promising avenues for future model development.

It is able to run whole experimental designs, and compute and display the associative values of elemental and compound stimuli simultaneously, as well as use extra configural cues in generating compound values; it also permits change of the US parameters across phases. The simulator produces both numerical and graphical outputs, and includes a functionality to export the results to a data processor spreadsheet. The book " The significance of this book lies in its theoretical advances, which are grounded in an understanding of computational and biological learning.

The approach taken moves the entire field closer to a watershed moment of learning models, through the interaction of computer science, psychology and neurobiology. A double error dynamic asymptote model of associative learning.

The models can reproduce and predict experimental results under different conditions. Explanations for the observed behaviors can be derived from the observation of the model variables in a given simulated experiment. Skip to main content Skip to table of contents.
