Lecture 6: Performing under pressure 2: Contemporary approaches Flashcards
1
Q
Under anxiety
A
- Skill focus -> too much attention on movement execution
- Distraction -> too little attention on task-relevant info
- For experts, attending to movement execution is not task-relevant
- For experts, skill focus = distraction

Q
Is attention really everything? no - other changes when person anxious
A
- Pressure -> anxiety -> attention, ?…
- Assumption 1: Multilevel effect = majority of literature explains effects of anxiety at attentional level
= attention -> interpretation -> physical response e.g. muscle tension - Assumption 2: performance is a process
= 99% of anxiety-performance lit. based on closed-skill execution
= many actions possible in a sport situation (anxiety may reduce options we can see)
= perception -> selection -> action
= don’t look at action phase of movement

Q
Level 1: (Visual) attention
A
- Under-anxiety = increased attention for threat-related info (source of threat, response to threat)
- Visual attention but also thoughts
- Experiments = subjects watch screen
= given threat and then have to re-direct their gaze to cross
= subjects either high or low anxious
= anxious individuals -> quicker to detect threat cue (inhibition function)
-> slower to disengage from threat que (shifting function)

Q
Wilson et al. study (2009) = attention
A
- Under-anxiety = bias towards threat-related interpretation
- Threat-related interpretation bias = what we listen to/look at is not always what we hear/see
= Calvo & Castillo (2001) -> anxious vs. non-anxious subjects
-> hear words and spell them out e.g. die vs. dye
-> anxious people spell threatening words
5
Q
Studies on interpretation
A
- Stefannuci et al. (2008) = anxious people perceive slope as steeper
- Changes in interpretation affect action selection
- Rock-climbing study (Net et al. 2008) = eyetracking: more fixations when anxious but same holds scanned
= perceived capability: reduce in perceived reachability under high threat
= Anxious people may use more holds to get to location & grasp holds that are closer as handholds appear further away

Q
Level 3: Physical Responses
A
- Under-anxiety = neurophysiological changes to facilitate quick avoidance responses
- Increased corticospinal excitability (to facilitate quick response)
- Avoidance motivation (to facilitate response direction)
- Increases muscle tension affects movement fluency
- When people look at more threatning pics, increased muscle response to allow quick physical response
- People on climbing with anxiety = increased use of force, less fluent movements
7
Q
Avoidance motivation in soccer (Jordet & Hartman, 2008)
A
- Study analysed penalty shootout
Negative valence shots (losing)
= Preparation time decreases in higher pressure shot
= avoid looking at GK
= decreases % goals - Anxiety increases importance of doing well -> extra effort
