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 efforts 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.

Anxiety, movement kinematics, and visual attention in elite-level performers.

We tested the predictions of Attentional Control Theory (ACT) by examining the effect of anxiety on attention control and the subsequent influence on both performance effectiveness and performance efficiency within a perceptual-motor context. A sample (N = 16) of elite shotgun shooters was tested under counterbalanced low (practice) and high (competition) anxiety conditions. A head-mounted, corneal reflection system allowed point of gaze to be calculated in relation to the scene, while motion of the gun was evaluated using markers placed on the barrel which were captured by two stationary cameras and analyzed using optical tracking software. The quiet eye (QE) duration and onset were analyzed along with gun barrel displacement and variability; performance outcome scores (successful vs. unsuccessful) were also recorded. QE (Vickers, 1996) is defined as the final fixation or tracking gaze that is located on a specific location/object in the visual display for a minimum of 100 ms. Longer QE durations have been linked to successful performance in previous research involving aiming tasks. Participants demonstrated shorter quiet eye durations, and less efficient gun motion, along with a decreased performance outcome (fewer successful trials) under high compared with low anxiety conditions. The data support the predictions of ACT with anxiety disrupting control processes such that goal-directed attention was compromised, leading to a significant impairment in performance effectiveness.

A test of processing efficiency theory in a team sport context

In this study, we tested some key postulates of Eysenck and Calvo’s processing efficiency theory in a team sport. The participants were 12 elite male volleyball players who were followed throughout the course of a competitive season. Self-report measures of pre-match and in-game cognitive anxiety and mental effort were collected in groups of players high and low in dispositional anxiety. Player performance was determined from the statistical analysis of match-play. Sets were classified according to the point spread separating the two teams into one of three levels of criticality. Game momentum was also analysed to determine its influence on in-game state anxiety. Significant differences in in-game cognitive anxiety were apparent between high and low trait anxiety groups. An interaction between anxiety grouping and momentum condition was also evident in cognitive anxiety. Differences in set criticality were reflected in significant elevations in mental effort, an effect more pronounced in dispositionally high anxious performers. Consistent with the predictions of processing efficiency theory, mental effort ratings were higher in high trait-anxious players in settings where their performance was equivalent to that of low trait-anxious performers. The usefulness of processing efficiency theory as an explanatory framework in sport anxiety research is discussed in the light of these findings.

The role of effort in moderating the anxiety – performance relationship: Testing the prediction of processing efficiency theory in simulated rally driving

Abstract We tested some of the key predictions of processing efficiency theory using a simulated rally driving task. Two groups of participants were classified as either dispositionally high or low anxious based on trait anxiety scores and trained on a simulated driving task. Participants then raced individually on two similar courses under counterbalanced experimental conditions designed to manipulate the level of anxiety experienced. The effort exerted on the driving tasks was assessed though self-report (RSME), psychophysiological measures (pupil dilation) and visual gaze data. Efficiency was measured in terms of efficiency of visual processing (search rate) and driving control (variability of wheel and accelerator pedal) indices. Driving performance was measured as the time taken to complete the course. As predicted, increased anxiety had a negative effect on processing efficiency as indexed by the self-report, pupillary response and variability of gaze data. Predicted differences due to dispositional levels of anxiety were also found in the driving control and effort data. Although both groups of drivers performed worse under the threatening condition, the performance of the high trait anxious individuals was affected to a greater extent by the anxiety manipulation than the performance of the low trait anxious drivers. The findings suggest that processing efficiency theory holds promise as a theoretical framework for examining the relationship between anxiety and performance in sport.

Anxiety symptom interpretation and performance predictions in high-anxious, low-anxious and repressor sport performers

This study examined whether the tendency to interpret anxiety symptoms as facilitative was more a characteristic of individuals classified as repressors than high-anxious and low-anxious sports performers. The influence of the cognitive biases of high-anxious and repressor individuals on future performance expectations was also examined. The state anxiety levels, directional interpretation of anxiety and performance expectations of golfers classified as high-anxious, low-anxious and repressors were examined prior to competition. Performance expectations were compared to actual performances achieved. The proposal that repressors would interpret anxiety symptoms as more facilitative than high-anxious and low-anxious individuals was not supported. Repressors were found to be overly optimistic regarding future performance, consistently predicting better performance than they achieved. Contrary to predictions, performance expectations of the high-anxious group did not differ from those actually achieved. Thus, the proposal that high-anxious individuals would be overly pessimistic was not supported. These findings are discussed within the theory of trait anxiety proposed by Eysenck (1997).

Theory and practice in sport psychology and motor behaviour needs to be constrained by integrative modelling of brain and behaviour

Because of advances in technology, the non-invasive study of the human brain has enhanced the knowledge base within the neurosciences, resulting in an increased impact on the psychological study of human behaviour. We argue that application of this knowledge base should be considered in theoretical modelling within sport psychology and motor behaviour alongside existing ideas. We propose that interventions founded on current theoretical and empirical understanding in both psychology and the neurosciences may ultimately lead to greater benefits for athletes during practice and performance. As vehicles for exploring the arguments of a greater integration of psychology and neurosciences research, imagery and perception–action within the sport psychology and motor behaviour domains will serve as exemplars. Current neuroscience evidence will be discussed in relation to theoretical developments; the implications for sport scientists will be considered.

Observation of meaningful activities: a case study of a personalized intervention on poststroke functional state

BACKGROUND AND PURPOSE Stroke rehabilitation coordinated by specialist teams and oriented toward functional activities is now common. However, the potential remains for improved outcome, and new methods for improving rehabilitation are being developed. Observation of functional, meaningful activities, via DVD, has been suggested as a technique that may be effective. This case study aimed to investigate the effect of an individualized program of observation for functional status after stroke. CASE DESCRIPTION The case study participant was a 44-year-old man, 12 months after a right intracerebral hemorrhage, with a Scandinavian Stroke Scale (SSS) score of 42. He was independently mobile using a cane. He viewed, with the instructions to understand and imitate, four DVDs of meaningful daily activities filmed from first- and third-person visual perspectives. Pre- and postintervention measures administered in the participants home were the SSS, Postural Assessment Scale (PASS), Timed Up and Go test (TUG) with manual and cognitive components, a fluidity scale, and the Stroke-Specific Quality of Life Scale. OUTCOMES Improvements were observed in the TUG and the fluidity scale. Small but clinically insignificant changes were observed in the PASS. The patient also felt confident to progress to walking without his cane. DISCUSSION The findings suggest that, for this relatively young and motivated individual, observation of meaningful activities was an important part of his stroke rehabilitation.

Influence of Defensiveness on Disability in a Chronic Musculoskeletal Pain Population.

This study aimed to identify the following: (1) the proportion of the defensive high‐anxious personality type in a chronic pain population; (2) whether personality type affects the relationships between cognitive factors and disability.

A qualitative investigation of factors that matter to individuals in the pain management process

Abstract Objective: Chronic musculoskeletal pain is a complex condition to manage with widespread consequences including physical disability, psychosocial effects and increased use of healthcare. Previous research has found patients’ experiences within health care can be influenced by factors such as expectations, therapist characteristics and treatment process. This study used patient interviews to identify the key factors that influence individuals’ experiences in the management of chronic pain. Design: Qualitative study using semi-structured interviews in either a home or hospital setting. Methods: Semi-structured interviews were conducted on eight participants attending hospital-based pain management. Participants were asked about their experiences of pain management and living with a chronic pain condition. Interviews were transcribed and analysed thematically. Results: Three main themes were identified; impact of their condition on daily life, clinical interactions and the pain management process. Understanding the condition was a key factor for the patients, in particular, explanation by the clinician. The temporality of their pain meant timing of appointments was critical. Patients reported factors such as family days and follow-up sessions would improve their treatment experience. Conclusions: This study highlighted important factors for healthcare professionals and patients in the management of chronic pain. Participants indicated a desire to understand their condition and learn strategies for self-management to allow them to cope better. As patients found benefit from being involved in the management process, discussions around the options for treatment may enhance management and rehabilitation. It is important we continue to research factors important to individuals with musculoskeletal pain to find an effective, evidence-based framework for understanding and managing this condition. Implications for rehabilitation This study highlights the importance to patients of being given information to help them understand their pain condition and to learn strategies for self-management to cope better. Where information was not provided and inadequate time allowed for questioning and discussion, patients tended to desire more frequent access to the care services. More effective communication may result in reduced demand and more efficient management. Patients suggested that ongoing peer support may offer an alternative to clinician-led services.

Personality Type Influences Attentional Bias in Individuals with Chronic Back Pain

Attentional biases reflect an individual’s selective attention to salient stimuli within their environment, for example an experience of back pain. Eysenck suggests that different personality types show different attentional biases to threatening information. This study is the first to test Eysenck’s theory within a chronic back pain population by investigating the attentional biases of four different personality types using a back pain specific dot-probe paradigm. Participants were 70 volunteers (45 female) recruited from a back rehabilitation program at an NHS Trust. The four groups were selected on their trait anxiety and defensiveness scores: defensive high-anxious; high-anxious; repressor and non-extreme. Participants completed a dot probe task comprising 20 practice trials and 250 experimental trials. The experimental trials contained 100 threat-neutral pairs, 100 positive-neutral pairs and 50 neutral-neutral image pairings. The threat images were taken from the Photograph Series of Daily Activities (PHODA) and the neutral and positive images from the International Affective Picture System (IAPS) image bank. The results provided partial support for Eysenck’s theory; defensive high-anxious individuals showed an attentional bias for threatening information compared to high-anxious individuals who demonstrated no bias. Repressors showed an avoidant bias to threatening images and an attentional bias to positive stimuli relative to neutral images. The clear difference in responses demonstrated by high-anxious individuals who vary in defensiveness highlight the need for separate investigation of these heterogeneous groups and help to explain the cognitive processes of defensive high-anxious individuals within a pain population. The demonstration of an attentional bias in this group to threatening information could explain why defensive high-anxious individuals are more likely to re-present for treatment.
