Performance quality and behavioral violations as crisis indicators in competition.

Investigated the relevance of task-related behavior (performance) and rule- and norm-related behavior (fairness and officials' response) to psychological crisis vulnerability during competitive situations. 31 tennis experts estimated the probability of such behaviors in crisis and noncrisis states. These estimates were used for calculating the components of diagnosticity (likelihood ratios) according to the Bayesian approach and later subjected to within-Ss ANOVAs. Results reveal that crisis and noncrisis conditions can be differentiated by all the variables as well as by their interactive impact. Vulnerability to crisis was associated mainly with unexpectedly poor performance, with unexpected and major violations, and with unexpected behavior to which officials respond. Expected behaviors were associated with noncrisis state. (French, Spanish, German & Italian abstracts) (PsycINFO Database Record (c) 2016 APA, all rights reserved)
