Anxiety
An aversive emotional state characterised by feelings of worry
Arousal
The state of an organism varying on a continuum from deep sleep to intense excitement
electroencelephagram (EEG) brain waves when increased anxiety/arousal
decreased sleep (theta waves) and increased excitement (beta waves)
electrocardiogram (EKG) heart rate when increased anxiety/arousal
increased heart rate
electromyogram (EMG) muscle tensionwhen increased anxiety/arousal
increased muscle tension
ventilation when increased anxiety/arousal
increased respiration rate and decreased tidal volume
blood pressure when increased anxiety/arousal
increased blood pressure
skin response when increased anxiety/arousal
increased sweating and decreased skin resistance
biochemical when increased anxiety/arousal
increased adrenaline and noradrenaline
social facilitation (Zajonc 1965) shows that
more arousal= increased likelihood of one’s dominant response - high arousal should hinder novice performance and help expert performance
the testing of social facilitation (maccracken and stadulis 1985)
examined the effects of arousal on children’s balance - balance pretest classified children as having high or low balance skill - results showed that low skill performance was worse in front of spectators
what are the problems with social facilitation
too simplistic and its predictions often fall short- can’t explain choking under pressure
inverted-U hypothesis (Yerkes and Dodson 1908)
increased arousal improves performance but only up to a certain point- further increases in arousal cause a gradual deterioration of performance
criticisms of social facilitation and inverted-U models
Arousal conceptualised as a uni-dimensional response - there is evidence for 3 distinct forms of arousal (electrocortical, autonomic, behavioural) Lacey 1967 - also cognitive appraisal of arousal symptoms can influence physiological measures (bandora 1997)
catastrophe model (Hardy 1990)
3D model that considers interactions between anxiety, arousal and performance
