Effects of performance anxiety on effort and performance in rock climbing: A test of processing efficiency theory

Abstract

Three studies examined the effort and performance of rock climbers in the context of processing efficiency theory. Anxiety was manipulated by different means in the three studies. In each study, the effort due only to the physical exertion of climbing was controlled for. Anxiety, effort, and performance were measured via self-report, an integrated heart rate measure, and belayer observation. Consistent with processing efficiency theory, the results showed that higher levels of anxiety were usually associated with higher levels of effort and commensurately higher levels of performance. However, the results also suggested that cognitive anxiety may not be the prime determinant of the effort and performance changes observed. Finally, the results suggested that other individual difference variables may play an important part in determining the extent to which individuals may be able to make use of anxiety-induced effort.

基于注意控制理论,采用反向眼跳范式,邀请48名运动员参加2项实验,考察竞赛特质焦虑对抑制功能的干扰效应。实验1(25人)为单因素组间设计,探讨竞赛特质焦虑对加工效能和操作成绩的影响。结果发现,竞赛特质焦虑提高眼跳方向错误率,不影响眼跳潜伏期,部分支持竞赛特质焦虑降低加工效能的假设;竞赛特质焦虑不影响按键准确率,支持竞赛特质焦虑不影响操作成绩的假设。实验2(23人)为两因素混合设计,在压力情境下探讨竞赛特质焦虑对加工效能和操作成绩的影响。结果发现,无论是在压力还是非压力情境下,竞赛特质焦虑均提高眼跳方向错误率,延长眼跳潜伏期,但不影响按键准确率,支持压力下竞赛特质焦虑降低加工效能而对操作成绩影响效果不明显的假设。综合2项实验,竞赛特质焦虑干扰抑制功能表现为降低抑制功能的加工效能但对操作成绩的影响效果不明显。本研究提示,注意控制理论适用于解释竞技运动领域焦虑与操作表现的关系。     

Anxiety‐induced performance catastrophes: Investigating effort required as an asymmetry factor

Two studies are reported that test the hypothesis that previous support for the cusp catastrophe model of anxiety and performance, and the hysteresis effect in particular, could have been due to a complex interaction between cognitive anxiety and effort required rather than between cognitive anxiety and physiological arousal. We used task difficulty to manipulate effort required in a letter transformation task. Experiment 1 (N=32) used high levels of trait anxiety together with a competitive environment to induce state anxiety. Experiment 2 (N=20) used a competitive environment with social pressure and ego threat instructions to induce high levels of worry. Both studies revealed significant three‐way interactions as hypothesized with follow‐up tests showing some support for the hysteresis hypothesis in Study 1, and strong support for the hysteresis hypothesis in Study 2. The findings support a processing efficiency theory explanation of anxiety‐induced performance catastrophes and indicate that two cusp catastrophe models of performance may exist; one that incorporates the interactive effects of cognitive anxiety and physiological arousal upon performance and the other that incorporates the interactive effects of cognitive anxiety and effort required upon performance.     

Anxiety and cognitive performance: attentional control theory

Attentional control theory is an approach to anxiety and cognition representing a major development of Eysenck and Calvo's (1992) processing efficiency theory. It is assumed that anxiety impairs efficient functioning of the goal-directed attentional system and increases the extent to which processing is influenced by the stimulus-driven attentional system. In addition to decreasing attentional control, anxiety increases attention to threat-related stimuli. Adverse effects of anxiety on processing efficiency depend on two central executive functions involving attentional control: inhibition and shifting. However, anxiety may not impair performance effectiveness (quality of performance) when it leads to the use of compensatory strategies (e.g., enhanced effort; increased use of processing resources). Directions for future research are discussed.     

Anxiety and Performance: The Processing Efficiency Theory

Abstract

Anxiety often impairs performance of “difficult” tasks (especially under test conditions), but there are numerous exceptions. Theories of anxiety and performance need to address at least two major issues: (1) the complexity and apparent inconsistency of the findings; and (2) the conceptual definition of task difficulty. Some theorists (e.g. Humphreys & Revelle, 1984; Sarason, 1988) argue that anxiety causes worry, and worry always impairs performance on tasks with high attentional or short-term memory demands. According to the processing efficiency theory, worry has two main effects: (1) a reduction in the storage and processing capacity of the working memory system available for a concurrent task; and (2) an increment in on-task effort and activities designed to improve performance. There is a crucial distinction within the theory between performance effectiveness (= quality of performance) and processing efficiency (= performance effectiveness divided by effort). Anxiety characteristically impairs efficiency more than effectiveness.     

Mathematics anxiety and mental arithmetic performance: An exploratory investigation

Abstract

Two exploratory studies were conducted to determine if mathematics anxiety, as assessed by the Mathematics Anxiety Rating Scale (MARS), is related to the underlying mental processes of arithmetic performance. MARS scores were higher when the test was administered by computer, vs. the standard paper-and-pencil format, and were higher for female than male college students. Small but significant processing differences in simple addition and multiplication were found when subjects were divided by quartiles into anxiety groups. Much larger differences in processing speed and accuracy were found with complex addition problems and a set of difficult problems (e.g. 9 × 16 = 134, true or false) that tested all four arithmetic operations. Overall, the low anxiety group was consistently the most rapid and accurate, the medium high was consistently the slowest, and the high anxiety group the most prone to errors. The results suggest that genuine performance differences exist among the several levels of mathematics anxiety, and that chronometric, reaction time-based studies of such performance will be useful in revealing those differences.     

Anxiety, learning, and memory: A reconceptualization

A new theoretical framework for work on anxiety and memory is proposed. Anxious subjects engage in task-irrelevant processing which preempts processing resources and some of the available capacity of working memory. They typically attempt to compensate for the adverse effects of this task-irrelevent processing on task performance by increased effort. It follows from these theoretical assumptions that anxiety will have differential effects on performance efficiency (i.e., the quality of performance) and on processing effectiveness (i.e., performance efficiency/effort). Anxiety will always reduce processing effectiveness, but will not impair performance efficiency if there is sufficient effort expenditure. Consequently, reliance on measures of performance efficiency will often obscure the detrimental effects of anxiety on processing effectiveness.     

Processing efficiency theory in children: working memory as a mediator between trait anxiety and academic performance

Working memory skills are positively associated with academic performance. In contrast, high levels of trait anxiety are linked with educational underachievement. Based on Eysenck and Calvo's (1992) processing efficiency theory (PET), the present study investigated whether associations between anxiety and educational achievement were mediated via poor working memory performance. Fifty children aged 11-12 years completed verbal (backwards digit span; tapping the phonological store/central executive) and spatial (Corsi blocks; tapping the visuospatial sketchpad/central executive) working memory tasks. Trait anxiety was measured using the State-Trait Anxiety Inventory for Children. Academic performance was assessed using school administered tests of reasoning (Cognitive Abilities Test) and attainment (Standard Assessment Tests). The results showed that the association between trait anxiety and academic performance was significantly mediated by verbal working memory for three of the six academic performance measures (math, quantitative and non-verbal reasoning). Spatial working memory did not significantly mediate the relationship between trait anxiety and academic performance. On average verbal working memory accounted for 51% of the association between trait anxiety and academic performance, while spatial working memory only accounted for 9%. The findings indicate that PET is a useful framework to assess the impact of children's anxiety on educational achievement.     

The impact of contextual priors and anxiety on performance effectiveness and processing efficiency in anticipation

It is proposed that experts are able to integrate prior contextual knowledge with emergent visual information to make complex predictive judgments about the world around them, often under heightened levels of uncertainty and extreme time constraints. However, limited knowledge exists about the impact of anxiety on the use of such contextual priors when forming our decisions. We provide a novel insight into the combined impact of contextual priors and anxiety on anticipation in soccer. Altogether, 12 expert soccer players were required to predict the actions of an oncoming opponent while viewing life-sized video simulations of 2-versus-2 defensive scenarios. Performance effectiveness and processing efficiency were measured under four conditions: no contextual priors (CP) about the action tendencies of the opponent and low anxiety (LA); no CP and high anxiety (HA); CP and LA; CP and HA. The provision of contextual priors did not affect processing efficiency, but it improved performance effectiveness on congruent trials. Anxiety negatively affected processing efficiency, but this did not affect the use of contextual priors or influence performance effectiveness. It appears that anxiety and prior contextual information impact attentional resources independent of each other. Findings are discussed with reference to current models of anticipation and anxiety.     

Anxiety,anticipation and contextual information: A test of attentional control theory

We tested the assumptions of Attentional Control Theory (ACT) by examining the impact of anxiety on anticipation using a dynamic, time-constrained task. Moreover, we examined the involvement of high- and low-level cognitive processes in anticipation and how their importance may interact with anxiety. Skilled and less-skilled tennis players anticipated the shots of opponents under low- and high-anxiety conditions. Participants viewed three types of video stimuli, each depicting different levels of contextual information. Performance effectiveness (response accuracy) and processing efficiency (response accuracy divided by corresponding mental effort) were measured. Skilled players recorded higher levels of response accuracy and processing efficiency compared to less-skilled counterparts. Processing efficiency significantly decreased under high- compared to low-anxiety conditions. No difference in response accuracy was observed. When reviewing directional errors, anxiety was most detrimental to performance in the condition conveying only contextual information, suggesting that anxiety may have a greater impact on high-level (top-down) cognitive processes, potentially due to a shift in attentional control. Our findings provide partial support for ACT; anxiety elicited greater decrements in processing efficiency than performance effectiveness, possibly due to predominance of the stimulus-driven attentional system.     

Effects of anxiety,a cognitive secondary task,and expertise on gaze behavior and performance in a far aiming task

ObjectivePrevious studies focused on investigating the separate effects of anxiety, cognitive load, and expertise on perceptual-motor performance, but the combined effects of these factors have not been studied yet. The objective of the current study was to investigate these factors in combination.DesignEleven expert dart players and nine novices performed a dart throwing task in low-anxiety (LA) and high-anxiety (HA) conditions with and without a secondary task.MethodTo manipulate anxiety the dart throwing task was performed low (LA) and high (HA) on a climbing wall with and without the secondary counting backwards task. Performance and efficiency of task execution and gaze behavior were assessed.ResultsThe anxiety manipulation evoked a decrease in dart performance, but only for the novices. Increases in mental effort and dart times and a decrease in response rate on the secondary task were observed for both groups. This shows that there were decreases in processing efficiency with anxiety. Most important, the anxiety-induced decrease in performance for the novices was accompanied by final fixations on the target that were substantially shorter and deviated off the target earlier. The dual task did not affect performance.ConclusionAnxiety affects efficiency and sometimes performance in far aiming tasks. Changes are accompanied by changes in gaze behavior, particularly the final fixation on the target. All in all, findings provide support for Attentional Control Theory as a suitable framework to explain the effects of anxiety, a cognitive secondary task, and expertise in far aiming tasks.     

The role of effort in influencing the effect of anxiety on performance: Testing the conflicting predictions of processing efficiency theory and the conscious processing hypothesis

The aim of this study was to test the conflicting predictions of processing efficiency theory (PET) and the conscious processing hypothesis (CPH) regarding effort's role in influencing the effects of anxiety on a golf putting task. Mid‐handicap golfers made a series of putts to target holes under two counterbalanced conditions designed to manipulate the level of anxiety experienced. The effort exerted on each putting task was assessed though self‐report, psychophysiological (heart rate variability) and behavioural (pre‐putt time and glances at the target) measures. Performance was assessed by putting error. Results were generally more supportive of the predictions of PET rather than the CPH as performance was maintained for some performers despite increased state anxiety and a reduction in processing efficiency. The findings of this study support previous research suggesting that both theories offer useful theoretical frameworks for examining the relationship between anxiety and performance in sport.     

Stress and work performance: The role of trait anxiety

Employees high in Trait Anxiety (TA) were found to exert greater work effort than those low in TA, which resulted in better sales performance. There was no relation between TA and work efficiency, measured by sales performance relative to work effort. Employees high in TA also reported greater levels of stress and more adverse effects of work on non-work relationships. Using multiple regression, both stress and interference with relationships were found to be better predicted by TA than work effort. The results are discussed in terms of laboratory-based theories about relations between TA and efficiency and intervention strategies for managing stress at work.     

Anxiety,coping and academic performance

Anxiety is a frequent response to stressful evaluation situations and may be correlated with the performance being evaluated. The present study investigated individual differences in social evaluation trait anxiety and coping dimensions as predictors of state anxiety and performance on a university examination. Separate multiple regressions were computed for coping assessed as a style, an individual difference measure, and as situational specific responses. Emotion-oriented coping predicted state anxiety in the evaluation situation. Social evaluation trait anxiety and task-oriented and emotionoriented coping responses predicted exam performance. The regression models predicted approximately a quarter of the variance in course grades. When coping was measured as a response, task-oriented coping response was a significant predictor of course grade. When coping was measured as a style or individual difference, avoidance-oriented coping style predicted aggregated course grade. It was suggested that different coping dimensions predict different outcomes and that coping be assessed over time to better understand its relation to performance.     

Implicit theories of intelligence and IQ test performance in adolescents with Generalized Anxiety Disorder

During the past decade, several studies have reported positive effects of cognitive-behavioral therapy (CBT) in the treatment of children and adolescents with mental disorders. One of the most important CBT interventions is to teach children and adolescents to challenge negative thoughts that lead to maladjusted behaviors. Based on the implicit theories of intelligence framework, the main purpose of this study was to test whether an incremental theory manipulation could be used to affect IQ test performance in adolescents with Generalized Anxiety Disorder (GAD). Results showed that patients demonstrated enhanced IQ performance and experienced less state anxiety when they were exposed to an incremental theory of intelligence manipulation. Our findings suggest that incremental theory manipulation provides a useful cognitive strategy for addressing school-related anxiety in adolescents with mental disorders such as GAD.     

Effects of anxiety on attentional allocation and task performance: An information processing analysis

An information processing signal detection methodology was employed to examine attentional allocation and its correlates in both normal comparison (NC) and generalized anxiety disorder (GAD) participants. In particular, the impact of neutral distractor and negative feedback cues on performance of an attention vigilance task was investigated. Individuals with GAD (N = 15) evidenced impaired performance on an attention vigilance task relative to NC participants (N = 15) when neutral distractor cues were presented. Contrary to prediction, no group differences in performance were detected under conditions in which participants were presented negative feedback cues they were told were relevant to their performance. Instead, GAD participants exhibited improvement during the experimental task such that their performance was equivalent to NC participants. Across trials, the clinically anxious group endorsed significantly higher levels of worry and negative affectivity; however, they failed to respond with concomitant physical arousal (e.g. increased muscle tension). These data are discussed within the context of Eysenck and Calvo's (1992, Cognition and Emotion, 6, 409–434) processing efficiency theory. Additionally, the results of this investigation provide support for Barlow's (1988, Anxiety and its disorders: The nature and treatment of anxiety and panic) conceptualization of anxiety as requiring the interaction of cognitive schema and physiological arousal.     

Benefits of all work and no play: the relationship between neuroticism and performance as a function of resource allocation

The authors evaluate a model suggesting that the performance of highly neurotic individuals, relative to their stable counterparts, is more strongly influenced by factors relating to the allocation of attentional resources. First, an air traffic control simulation was used to examine the interaction between effort intensity and scores on the Anxiety subscale of Eysenck Personality Profiler Neuroticism in the prediction of task performance. Overall effort intensity enhanced performance for highly anxious individuals more so than for individuals with low anxiety. Second, a longitudinal field study was used to examine the interaction between office busyness and Eysenck Personality Inventory Neuroticism in the prediction of telesales performance. Changes in office busyness were associated with greater performance improvements for highly neurotic individuals compared with less neurotic individuals. These studies suggest that highly neurotic individuals outperform their stable counterparts in a busy work environment or if they are expending a high level of effort.     

Effortful semantic decision-making boosts memory performance in older adults

A major concern in age-related cognitive decline is episodic memory (EM). Previous studies indicate that both resource and binding deficits contribute to EM decline. Environmental support by task manipulations encouraging stronger cognitive effort and deeper levels of processing may facilitate compensation for these two deficits. To clarify factors that can counteract age-related EM decline, we assessed effects of cognitive effort (four levels) and level of processing (LoP, shallow/deep) during encoding on subsequent retrieval. Young (YAs, N?=?23) and older (OAs, N?=?23) adults performed two incidental encoding tasks, deep/semantic and shallow/perceptual. Cognitive effort was manipulated by varying decision-making demands. EM performance, indexed by d-prime, was later tested using a recognition task. Results showed that regardless of LoP, increased cognitive effort caused higher d-primes in both age groups. Compared to YAs, OAs showed a lower d-prime after shallow encoding across all cognitive effort levels, and after deep encoding with low cognitive effort. Deep encoding with higher levels of cognitive effort completely eliminated these age differences. Our findings support an environmental-compensatory account of cognitive ageing and can have important therapeutic implications.     

State-trait anxiety and motocross performance

The prediction from state-trait theory that subjects low in anxiety will perform better than highly anxious subjects on a more difficult task was tested on a motocross competition. We analyzed the relationships among the entire rank order of finish and state and trait anxiety measured by State-Trait Anxiety Inventory for 32 motocross riders (males whose age ranged from 16 to 27 yr.) participating in a national competition in Italy. A negative correlation between performance (measured by rank at the finish of the competition) and state anxiety was noted. The r for state and trait anxiety scores was also negative, but that between performance and trait anxiety was nonsignificant. Additional studies of high level sport competition will provide data relevant to planning interventions to control athletes' anxiety.
