Document Summary
Lecture 25: person x situation interactions (april 10) Example: anxious/anxious, avoidant/avoidant don"t exist => people don"t put themselves in situation where their partners are inconsistent with expectations: people create situations. Differential susceptibility (or sensitivity hypothesis: a few statistical terms. Main effect : variable a has a direct effect on variable b. =>how do people respond when put in a particular role ? (ex prisoner/gard) Example: likelihood to harass and prime with sexist ads. Prime with sexist ads (regardless to your lsh, Or high in likelihood to sexually harass (regardless to your condition, if you are high in lsh. Interaction effects: when the effet of variable a on variable c depends on the effect of variable c. Ex: attachment lecture, we talk about support seeking. Interaction between amount of anxiety, level of secutiry or avoidance. Mesure of rejection sensibility, met the a person, a person quit the study (no explanation or explanation that had to leave)
