Architecture of the conflict adaptation model by Botvinick et al. (2001). The stimulus layer contains one unit for each combination of arrow type (<= left arrow, >= right arrow) and stimulus position (L = left flanker, T = target, R = right flanker). The response layer contains one unit for each response (<= left response, >= right response). The attention layer contains one unit for each stimulus position. Conflict E(n), resulting as a function of activity in the response layer, is used to adjust the control parameter ext, which determines activity in the attention unit. Gray bars indicate the average distribution of activity across stimulus positions in the attention layer.
