Working with a sleep-deprived or a cognitively enhanced team member compromises motivation to contribute to group performance
- Abstract:
-
How does knowing another team member is cognitively impaired or enhanced affect people's motivation to contribute to the team's performance? Building on the Effects of Grouping on Impairments and Enhancements (GIE) framework, we conducted two between-subjects experiments (Ntotal = 2,352) with participants from a representative, nationwide sample of the working population in Germany.
We found that another group member's impairment (sleep deprivation) and enhancement (taking enhancement drugs) lowered participants’ intentions to contribute to the team's performance. These effects were mediated by lowered perceived competence (enhancement and impairment) and warmth (only enhancement) of the other group member. The reason for being impaired or enhanced (altruistic vs. egoistic reason) moderated the indirect effect of the impairment on intended effort via warmth.
Our results illustrate that people's work motivation is influenced by the psychophysiological states of other group members. Hence, the enhancement of one group member can have the paradoxical effect of impairing the performance of another.
