1.Level of activation of the amygdala measured by fMRI during the 1st stage of the experiment when participants were exposed to each of the 96 scenes
2. Measure of memory when participants had to recognize the images 3 weeks after the initial experiment |

| Had to choose from 4 buttons to indicate emotional arousal on a scale of: Zero (0) Not emotionally intense at all to Three (3) Extremely emotionally intense |

| • Females were chosen because they are more likely to respond physiologically and more likely to report intense emotional experiences • Right- Handed • Healthy |

Definition
Participants’ experience of emotional intensity in the present study correlated well with average ratings of emotional valence and arousal.
The participants arousal is correlated with higher emotional intensity
That the participants performance when remembering the images was higher for the most emotionally intense images |

| The experiment was conducted in a lab, in an fMRI which could activate the participants amygdala already, it could also provide an artificial feel and could not represent to population in the real world. |

Average correlation coefficients between Ps intensity ratings, on one hand, and normative valence and arousal, on the other, were -0.66 and 0.68
Im still really confused on the correlation coefficients and what they mean |
