However, it has been found that collective inhibition may be due to sources other than social loafing, as offering a monetary incentive have been evidenced to fail to produce an increase in memory for groups[4] Further evidence from this study suggest something other than social loafing is at work, as reducing evaluation apprehension – the focus on one’s performance amongst other people – assisted in individuals’ memories but did not produce a gain in memory for groups. Personal accountability – drawing attention to one’s own performance and contribution in a group – also did not reduce collaborative inhibition. Therefore, group members’ motivation to overcome the interference of group recall cannot be achieved by several motivational factors.
