A neurocomputational model is extended to address relevant data in a version of the Eriksen flanker task that allows investigation of stimulus- and response-conflict. The conflict-monitoring framework by Botvinick and colleagues proposes that response-conflict is higher in incongruent conditions compared to congruent or neutral conditions and that increases in conflict lead to increased control on subsequent trials. A computational study is presented in which the conflict-signal is (a) computed at every level of processing (response, stimulus) and is (b) used to modulate the input in the same trial. Results show that the models capture (1) the profile of distributional plots seen in the behavioral literature and (2) the patterns of hemodynamic responses seen in the neuroimaging literature. Suggestions for a combining neuroimaging and behavioral analyses are discussed. |
