A Theory of Challenge and Threat States in Athletes: A Revised Conceptualization

There was support for many of the 15 predictions in the TCTSA, with two main areas for reflection identified: to understand the physiology of challenge and to re-evaluate the concept of resource appraisals. This re-evaluation informs the TCTSA-R, which elucidates the physiological changes, predispositions, and cognitive appraisals that mark challenge and threat states. First, the relative strength of the sympathetic nervous system response is outlined as a determinant of challenge and threat patterns of reactivity and we suggest that oxytocin and neuropeptide Y are also key indicators of an adaptive approach to motivated performance situations and can facilitate a challenge state. Second, although predispositions were acknowledged within the TCTSA, how these may influence challenge and threat states was not specified. Third, in the TCTSA-R, a more parsimonious integration of Lazarusian ideas of cognitive appraisal and challenge and threat is proposed. This reflects polychotomy of four states: high challenge, low challenge, low threat, and high threat.

This manuscript provides a critical review of the literature examining challenge and threat in sport, tracing its historical development and some of the current empirical ambiguities. To reconcile some of these ambiguities, and utilizing neurobiological evidence associated with approach and avoidance motivation c. For example, rather than see challenge and threat as opposite ends of a single bipolar continuum, the ESM implies that individuals could be 1 challenged, 2 threatened, 3 challenged and threatened, or 4 neither challenged or threatened by a particular stimulus. From this perspective, it could be argued that the appraisal of some sport situations as both challenging and threatening could be advantageous, whereas the current literature seems to imply that the appraisal of stress as a threat is maladaptive for performance. The ESACT provides several testable hypotheses for advancing understanding of challenge and threat in sport and we describe a number of measures that can be used to examine these hypotheses. In sum, this paper provides a significant theoretical, empirical, and practical contribution to our understanding of challenge and threat in sport.

Challenge and threat states predict future performance; however, no research has examined their immediate effect on motor task performance. The present study examined the effect of challenge and threat states on golf putting performance and several possible mechanisms. One hundred twenty-seven participants were assigned to a challenge or threat group and performed six putts during which emotions, gaze, putting kinematics, muscle activity, and performance were recorded. Challenge and threat states were successively manipulated via task instructions. The challenge group performed more accurately, reported more favorable emotions, and displayed more effective gaze, putting kinematics, and muscle activity than the threat group.

Although teachers around the world have different styles and standards for learning, there is one thing on which they seem to agree: a computer is no match for a classroom as a place for kids to learn. They gave it an average score of five out of ten Exhibit 1. The grades were especially harsh from teachers in Japan and the United States, where nearly 60 percent rated the effectiveness of remote learning at between one and three out of ten.

Manipulating cardiovascular indices of challenge and threat using resource appraisals.

There are few more demanding working environments than that faced by security and elite military personnel. The situations faced are uncertain, changeable and dangerous requiring accurate decision-making, skilled movement and co-ordinated action. Understanding how people respond psychologically and physiologically in demanding settings has been the focus of research that I and colleagues have undertaken over the last 10 years. We have explored the subtle psychological and physiological differences that indicate whether a person is challenged or threatened under demanding conditions, why a person who is challenged performs better, and how social interaction, leadership and lifestyle can influence these responses. The terms challenge and threat are used to describe psychological and physiological differences that relate to performance.

Food craving has been shown to induce states of psychological challenge, indexed by increases in adrenaline but not cortisol production. The study aimed to test the relationship between challenge and 1 desire thinking the active processing of the pleasant consequences of achieving a desired target and planning how to do so and 2 craving. They were then presented with situations in which their craving would be fulfilled or not via a false feedback practice task a wordsearch task. During this period psycho-physiological measures of challenge and threat were taken. Higher levels of craving were linked to challenge only when the craved object was likely to be obtained.

Gratitude-based interventions are effective in facilitating positive relationships and increasing life satisfaction. However, for some individuals e. In this study, we expected to replicate this gratitude expression threat effect. Moreover, we aimed to understand psychophysiological mechanisms of this effect by accounting for cognitive, motivational, and physiological responses to gratitude expression in line with the biopsychosocial model of challenge and threat. Their cardiovascular reactivity was monitored continuously. We found that individuals with higher depression and lower trait-gratitude were less likely to initiate gratitude intervention.
