Mem: EWT- anxiety AO3

Question 1

Strength- supportive evidence which replicate the Yerkes-Dodson principle

Answer 1

-Valentine and Mesout- ppts describe someone the Labyrinth of Horror- high/low anxiety groups based on heart rate/questionnaires
-high anxiety recalled least details, only 17% chose actor in a line-up- 75% of low anxiety subjects.
-Anxiety disrupted the ppts recall, objective + subjective measures (heart rate questionnaires)
-high anxiety lvl does impact recall of an event

Question 2

Limitation- Johnson and Scott, construct validity- may have been researching surprise, not anxiety

Answer 2

-Pickel created contrasting conditions in a hair salon, confeds carried scissors/gun/chicken (IV), DV= recall accuracy
-accuracy lower with unusual conditions
-could suggest WFE is due to surprise not anxiety, chicken +gun= same results
-may not tell us anything about effect of anxiety on EWT

Question 3

Limitation- yuille and cutshall- field experiment, but research design lacks control, so internal validity questioned

Answer 3

-ppts may have discussed between themselves during study, may have read News articles
-confounding variables may influence recall + anxiety
-but, low internal validity, but higher ecological validity than lab exps
-so results may show more effects about anxiety on EWT in real life
