Seventeen psychology students participated in a group comparison of the effects of participative decision making, defined as subject decision making in three areas of the experiment, expected payment, and no expected payment on performance of a repetitive scanning task. Measures of performance quantity and quality were assessed directly, while satisfaction and manipulation checks were evaluated via selfreport. Clerical pretest scores were used as covariates in an analysis of covariance, which revealed no significant differences on the quantity dimension but-highly significant differences (p = .03) for quality (error) performance. The findings, which may have been biased by an experimenter "instruction" effect, point to the effectiveness of participation in facilitating quality control.
