Role of task strategy and stimulus processing in reflective and impulsive tactual matching performance

14 reflective and 14 impulsive boys performed tactual matching tasks in which frequency of observation of the standard was manipulated by successive or simultaneous presentation and in which stimulus features were controlled so that the amount of stimulus analysis carried out might be inferred. The results suggest that an impulsive performance was improved by simultaneous presentation of the stimuli but even in this condition the impulsive subjects did not carry out an adequate amount of stimulus analysis.
