Trying Harder for Different Reasons

Summary: Past investigations of performance on a conjunctive physical persistence task have yielded consistent evidence of motivation gains in the less able worker - a pattern first seen in data collected over 70 years ago (Kohler, 1926, 1927). Moreover, recent work indicates that these gains are due to the increased instrumentality of the weaker participant's efforts. The present study sought to demonstrate that another potential factor in the work context - the sex composition of the group, which is known to moderate self-presentation concerns - could also affect such motivation gains. Male and female members of work teams performed a physical persistence task. In one condition they performed work trials as individuals. In others, they first worked on the task alone and then were paired with a more capable same- or other-sexed teammate to perform the task conjunctively - i. e., this trial was over as soon as either person stopped. As expected, these less capable participants worked significantly harder ...
