Performance during competition and competition outcome in relation to testosterone and cortisol among women.

A contribution to a special issue on Hormones and Human Competition. This study investigated the relation between competition, testosterone (T), and cortisol (C) in women. One hundred and twenty female participants competed against a male confederate in a computerized laboratory task. The task was preprogrammed so that half the women won and half of the women lost the competition. T and C concentrations were measured in saliva samples collected at four time points before and after the competition. Accuracy and reaction time during the competition were recorded. T and C increased directly after the competition, though not significantly for C, and then decreased over time regardless of the competition outcome. Regression analyses demonstrated that baseline T was significantly and positively associated with competition accuracy, though only in individuals who were low in C. Individuals who were high in C showed no relation between T and accuracy. This relation was further qualified by competition outcome. Losers of the competition showed a significant positive relation between baseline T levels and competition accuracy, though only if they were low in C. No relation was found between T and accuracy in losers who were high in C. Winners of the competition showed no relation between T and accuracy, regardless of whether C levels were high or low. These results are in line with the dual-hormone hypothesis, whereby the effects of T on status-seeking behaviors are dependent on C levels for individuals whose status is threatened.

Anxiety and cognition.

In this review we discuss the interplay between anxiety and cognition, illustrating how anxiety can compromise performance on cognitively-demanding tasks and lead people to perform below their ability. Using math anxiety and test anxiety as examples, we highlight key findings from psychology, cognitive science, and neuroscience, to show that how one approaches an anxiety-inducing situation can have a large impact on how that person ultimately performs. We end by discussing who is most susceptible to anxiety-induced poor performance and suggest promising techniques which may help to reduce the negative impact of anxiety on performance.
