| Abstract | A simple random-guessing model of the dichotic two-response paradigm is used to predict the proportions of single- and double-correct responses at different performance levels. Comparisons with real data show that the proportions of double-correct responses are generally overpredicted. By introducing an additional free parameter to account for nonindependence of channels (ears), the model is made to fit closer to empirical data, but the value of the parameter is not the same for different sets of data. This may be due to differences in stimulus characteristics between experiments. While the model is oversimplified in many ways, it nevertheless provides a rudimentary formal framework for the interpretation of dichotic data, particularly with regard to changes in the proportions of single- and double-correct responses with performance level. |
