Peer Evaluation Systems (PESs) allow members of student teams to provide one another with computer-mediated feedback in the form of qualitative, open-ended comments. The current research leverages unsupervised Natural Language Processing (NLP), namely Biterm Topic Modeling (BTM) and sentiment analysis, to uncover latent topics and degree of positivity and negativity expressed in peer feedback, respectively. BTM results revealed a 6-topic model that was reliably replicated over 10 Gibbs initializations 80% of the time. Topics were labeled Timely Communication, Idea Generation, Coordination & Adaptation, Work Quality, Team Support & Focusing, and Work Accountability. Qualitative comparison suggests that these topics demonstrate …

The purpose of the present study was to assess the effects of accountability on leniency reduction on self- and peer ratings on team-based performance appraisals when they were used for different purposes (developmental versus evaluative purposes). Accountability was operationalized as participants being told they would have to justify their self- and peer ratings of team behaviors to a local nuclear process control plant supervisor (lab study) or to their professors (field study). In the lab study, purpose was operationalized as participants being told that they would have to complete the Team Behaviors Form (TBF) to receive course credit. In the …

Past teamwork stress literature has experienced contradictory findings. As more reliable models of teamwork emerge, there is still a noticeable lack of information regarding how stress affects teamwork processes. This paper first reviews the current state of the team stress literature, where two types of stress for teams are explored: qualitative and quantitative stress. A meta-analysis examined the current literature on quantitative stress and the impact on team performance and effectiveness. Results from nine independent samples (N = 1,794) indicated that quantitative stress has a negative effect on team outcomes, ῤ = -.41. Second, a lab study sought to discover …
