متن کاملProblem-solving performance with task overload: Effects of self-pacing and trait anxiety
Ninety-two subjects solved a series of problems without enough time to finish and worked either at a pace and in an order determined by the experimenter (experimenter-paced) or at their own pace and order under self-administered time deadlines (self-paced). Self-pacing resulted in superior performance on rote and poorer performance on cognitive problems relative to experimenter-paced groups. Se...
