stress and anxiety Flashcards
Arousal definition
general physiological and psychological activation varying on a continuum from deep sleep to intense excitement (Gould and Krane 2002)
HULL 1943- drive theory (arousal)
linear relationship
more psyched up= better performance
increased drive (arousal) will increase the likelihood of dominant behaviour- as pressure increases perforamnce increases
-so when arousal is high performance is high
disadvantages to this theory=but just coz its dominant does not mean it will be correct or may be novices so will not perform well
BUT even highly skilled players may choke in highly charged situations like a penalty shoot out
so for the theory to be correct the skill must be well learned or it might actually be a negative relationship
Yerkes an Dodson 1908- inverted U hypothesis
predicts performance effectiveness will increase as arousal will increase to an optimal point- after this point there will be a decrease in performance
At low and high levels of arousal, performance will be lowered compared to moderate levels of arousal
recent evidence supports this- Landers and Arent 2010
Criticism (Gould and Udry 1994; Hardy 1990)- is the optimal level arousal always at this mid point
what about the nature of the task e.g. simple a complex tasks=- surely we cant have the same optimal point for simple and complex tasks
Anxiety
A negative emotional state with feelings of nervousness, worry and apprehension associated with activation or arousal of the body
Types of anxiety
trait- aspect of our personality- those with high trait anxiety will usually have high levels of state anxiety in highly competitive situations- however they can learn coping skills to overcome this anxiety. Knowing some ones trait anxiety will be a good predictor
state anxiety- how you feel right now in the current situation- this is multidimensional so we look at it from a cognitive and somatic view point and behavioral
cognitive anxiety
concerned with extent to which one worries or has negative thoughts- lack of self confidence/ sense of worry, fear, doubt/ attention can be disrupted/worrisome expectation of failure
somatic anxiety
concerned with moment to moment changes in ones perception of physiological activation (physiological changes)- unusual feelings of nausea/ increased HR/ increased BP/ increased muscle tension/ increased perspiration
Behavioural anxiety
tense facial expression, changes in communication
Stress
A substantial imbalance between demand and response capability, under conditions where failure to meet that demand is hgih
fight or flight response- HR, pupils dilate, sweating, glycogen to glucose
The stress process
stage 1- enviromental demand
stage 2- individuals perception of the environmental demand
stage 3- stress response - arousal/state anxiety/muscle tension/attention changes
stage 4- behavioural consequences- performance or outcome
what causes anxiety and stress?
situational sources- the more important the event the more stressful/ too much pressure and high expectations also lead to anxiety (also low expectations relating to performance
Individual factors; Trait anxiety/ performance concerns/ locus of control (those who need high control)/ self esteem/ social physique anxiety- anxiety when others observe their physiques
Cognitive and somatic anxiety-
time to event paradigm- Martens et al 1990
CSAI-2= measure cognitive anxiety, somatic
findings- cognitive anxiety is high 48 hrs before competition- high and stable
somatic anxiety was low leading up to competition
But getting closer to competition somatic anxiety started to increase.
This is crucial to understand as a coach - those who have anxiety they will definitely go through this process- understanding individual differences are very important e.g. normally loud performers go quiet
Multidimensional state anxiety-
Burton et al 1988 study
Burton et al 1988- ‘Do anxious swimmers swim slower’
Findings- cognitive anxiety somatic and self confidence have different relationships with performance
cognitive anxiety has a negative relationship with performance
self confidence has a positive relationship with performance
somatic anxiety- performance will increase up to a certain point
these relationships were strongest in short duration events
Woodman and Hardy 2003- meta analysis on anxiety and performance in sport
48 studies investigating cognitive anxiety and self confidence subscales
higher standard athletes experienced more cognitive anxiety
males other than females displayed higher cognitive anxiety and self confidence
anxiety and performance in sport-
why are findings inconsistent
Anxiety often impairs performance on ‘;difficult’ tasks-Eysenck and Calvo 1992-
why its inconsistent- Anxiety is complex/ in event coping strategies/ self report measures/ task characteristics
