Guardia 2012 Flashcards
What are the aims of Guardia (2012)
To see whether people with anorexia can predict if they can get through a door way compared to them predicting if a different person could get through the same door way compared to a control group
What was the sample for guardia 2012
50 young females, 25 healthy control 25 experimental from an easting disorder clinic from Lillie, France.
What was the calculated BMI for the control and experimental
Control - 22.06
Experimental - 15.645
What was the calculated body shape questionnaire results for the experimental and control groups and how did they calculate this?
Control - 66.708
Experimental - 123.96
Calculated from a questionnaire given to all ppts which asked questions about their drive for thinness and body dissatisfaction
Procedure- numbers for openings used
51 openings shown all 30-80cm in width, they were each shown 4 times and were projected onto a wall so it looked like a door.
Procedure- what were the two conditions?
1st person perspective
3rd person perspective
What happened in the 1pp condition
Ppts had to judge wether their own bodies would fit through the opening projected without turning to the side at a normal speed
What happened in the 3pp
Ppts had to judge whether the experimenter could fit through the openings, they could get up to have a better look if needed. The experimented had a shoulder width of 38cms.
How was the perceived critical opening calculated
By finding the shoulder width of the ppts and dividing them by the widths of the opening. If the ratio was 1 or below the ppts would not be able to get through, if there was a ratio of above 1 then there was a margin to get through the door
Results for guardia 2012 1pp
AN Much higher score on body shape questionnaire
AN Much worse at estimating their body size, saying that they would not be able to fit through openings that were much larger then themselves. Perceptual ratios - 1.321 compared to control group that was 1.106.
Results for guardia 2012 3pp
AN patients were much better at predicting the experimenters body shape compared to how they predict if they can get through themselves - AN, 1.227 control, 1.137 no sig difference in groups.
Conclusions guardia 2012
People with AN have severe body perception issues and will regularly think that that are larger than they really are, this is shown by the fact that they rate their own possibility of getting through lower than when they rated the experimenter. This could be because their schemas have not changed since their weight loss, meaning that they will still think of themselves as larger than they are.
