Evalute capafons 1998

G

volunteer sample via media advert

lowers generalisability because the pps were eager to be cured
of their flying phobia where as someone too scared to even try may have altered the results

eliminates bias

41 pps, both male and female

R

standardised procedure, easy to replicate

dependent variable - how scared the pps were

psychological measures

palm temperature

heart rate

muscular tension

timings

12-15 sessions

2 one hour sessions a week

V

he could've done a follow up session after a while to see if spontaneous recovery had occurred and if he had to do top up sessions

in vitro

treatment group shown video of a flight

capafons could have took them onto a real plane and maybe had a short flight

E

only half of the pps were in the treatment group, the other half were in the control group so even though they signed up to get treatment for their fear, they didn't get it

this is a violation on the BPS guidelines as they're being deceived so the study isn't very ethical

2 control groups

demand characteristics, motivated to recover

scales and surverys - EPAV = the occurrence of catastrophic events during the flight

physiological arousal exactly 3 minutes before showing them the video of a flight including flight activities e.g packing and being at the airport

8 weeks later they watched the video again and the DV was measured again

see whether the effects of systematic desensitisation were long lasting
