How witnessing rudeness can disrupt psycho-motor performance of dental students.

ABSTRACT

Rude and disrespectful behaviors are ubiquitous and pervasive in the workplace. The purpose of this study was to examine the effects of witnessed rudeness on dental student psychomotor performance. Using an experimental, between-subjects design, 71 2nd (Sophomore) year dental students witnessed either an experimental (rude) or control (neutral) condition in which a confederate lab manager interacted in a rude or neutral manner with a prospective lab assistant candidate. Students then performed a mock prosthodontics psychomotor examination as part of the fixed prosthodontics preclinical course. Results indicated that those students who arrived at the experimental session cognitively depleted (+1 SD above the mean) and were exposed to the rude condition were significantly more likely to make critical errors when performing a posterior bridge preparation, compared to those students in the control group. There were no significant differences between the rude and control conditions for participants who were not cognitively depleted (-1 SD below the mean). Overall, the findings indicate that for those dental students suffering from cognitive depletion, merely witnessing rudeness can have adverse impacts on psychomotor performance and potentially, eventual patient care.
