Women were chosen in this study because ...
they are more likely to report intense emotional experiences and show more physiological reactivity in concordance with valence judgments than men
they are less likely to report intense emotional experiences and show less physiological reactivity in concordance with valence judgments than men
they have better declarative memory than men and tend to find the fMRI less distressing

148
How were the images viewed?
through a mirror directed at a back-projection screen in the fMRI scanner
on a television screen just outside the fMRI scanner
through 3d glasses to make the scenes more intense
through a one way mirror so the researches could see them but they could not see the researchers
The images were chosen from the International Affective Picture System stimuli set which provided a normative rating for...
valence and arousal
males and females
right handers and left handers
encoding and recall
Valence of images ranged from ranged from...
highly negative to neutral
negative to neutral
negative to highly neutral
Normative ratings for arousal ranged from
tranquil to highly arousing
serene to terrifying
calm to intense
neutral to highly negative

3
4
5
6
The Pps were told that the buttons represented...
0 (“not emotionally intense at all”) to 3 (“extremely emotionally intense”).

12
48
96

The foils were selected so that they matched the...
