Lee Trevino: 'Pressure is playing for ten dollars when you don't have a dime in your pocket.'
Factors that increase the importance of performing well
Threats on ego in competitive sports
Monetary incentives
Pressure produces
Systemic stress response influencing endocrine, cardiovascular and muscular systems
Effects on cognitive functioning
Mediating role of cognitive biases on pressure-performance relations
Effects of cognitive biases on momentary state anxiety and attentional control
Choking
When inferior performance happens despite effort and incentives to do well
When superior performance is achievable but choked by anxiety under perceived pressure
Choking
An acute and considerable decrease in skill execution and performance when self-expected standards are normally achievable, which is the result of increased anxiety under perceived pressure
fMRI study
Negative correlation between frontal-motor functional connectivity and choking
Suggest choking is due to inadequate executive/frontal control resources.
Clutch performance
Incremental/ superior performance under pressure circumstances
Although most studies look at negative effects of pressure some have looked at positive effects.
Typical experimental studies on Pressure-Performance Relations
1. Low Pressure (Control) - Baseline measures (Pre-competition state anxiety)
3. High Pressure (Experimental) - Performance measures
The assumption has been that performance is worse in high pressure condition
Increased pressure leads to increased anxiety
Pressure is constant
There is a uni-directional link between pressure and performance
Expert performance is 'automatic'
Proceduralised
Skill representation does not require the same degree of attention and control as that at lower levels of practice.
Theoretical Frameworks
Drive theories
Attentional theories
Theoretical explanations for choking
Arousal/ Drive Theories
Attentional Theories
Self-focus theories of choking
Pressure situation increase anxiety and self-consciousness about performing successfully
This increases the attention paid to skill processes and their step-by-step control
Performance disruption then occurs due to the effortful allocation of attention to previously automated processes
Introducing a concurrent attentionally demanding task should impair novice performance.
Instructions directing participants to attend to aspects of skilled performance outside of conscious awareness of skilled performers should impair expert performance more than novice performance.
Evidence of expert 'skill focus' under pressure in real world settings is not robust.
Self focus theory/ weaknesses
Assumes that expert performance is fully automatic(not true because experts do have to think about the actions they take in certain situations)
There is intra-subject variability (e.g. final posture, movement components)
Strategic deployment of attention
Assumes that self focus is always detrimental
Attentional Control Theory (ACT)
ACT distinguishes between two variables: Performance effectiveness (quality of performance) and Processing efficiency (the r/ship between performance effectiveness and the resources used to achieve that performance level)
Its reduced by task irrelevant thoughts (worries, performance concerns)
The prediction is that anxiety impairs processing efficiency more than performance effectiveness
Attentional Control Theory (ACT)
The Goal-directed attentional system (Top down control of attention, involves the PFC)
Stimulus driven attentional system (Bottom-up control of attention – detection of behaviourally relevant sensory events)
Anxiety increases the influence of the stimulus-driven system and reduces that of the top-down system
Increases distractibility from task-irrelevant stimuli.
Act also assumes that negative effects of anxiety on processing efficiency are mediated by the working memory system.
Especially the central executive (top-down attentional system)
Inhibition (resistance to distractibility) and shifting (attentional allocation) relate well to ACT.
Attentional Control Theory: Sport (ACTS)
Addresses how pressure influences the individual's levels of anxiety and motivation (as in ACT)
And how these anxiety and motivation levels then influence performance
Feedback loops.
Anxiety impairs processing efficiency more than performance effectiveness
Anxiety reduces the efficiency of inhibition (Negative attentional control)
Anxiety reduces the efficiency of shifting (Positive attentional control)
Anxiety reduces the efficiency of shifting
Experts have superior attentional control
Processing efficiency vs performance effectiveness
Anxiety affects processing efficiency more than performance effectiveness (e.g., when relating performance effectiveness to self-reported effort)
Quiet eye
The final fixation on a location that is within 3 degrees of visual angle for a minimum of 100ms
Requires within task attentional control (shifting) as well as resistance to distraction (inhibition)
Positive r/ship between the duration of quiet eye and success (e.g., in darts, archery)
How is ACTS different from ACT
ACTS is more explicit than ACT about the initial determinants of anxiety
the role of feedback loops based on performance failure and errors;
the role of motivation in moderating the deployment of effort or processing resources;
the sporadic nature of attentional disruptions in trained sporting performers.
Determinants of Anxiety
Whether increased pressure leads to heightened anxiety depends on how cognitive biases alter the perceived probability and cost of poor performance.
Attentional biases
Interpretive biases (Threat)
This relationship is in turn influenced by fluctuations in the individual sportsperson's tendency to engage in performance monitoring.
Error monitoring
Increased error monitoring increases anxiety
Anxiety increases biases
Failure illustrates the bi-directional nature of the pressure –performance relationship
Adverse effects of failure on cognitive and motor performance are greater among individuals with anxious personalities
Perceived costs and p. of failure
Perceived probability and costs of future undesirable outcomes influences anxiety
Role of appraisals
Changes in perception of costs and p. of failure
Role of motivation and Effort
Highconfidence is associated with proactive control (goal directed attention)
Low confidence is associated with reactive control (stimulus driven attention)
