study
1
Q
Aim
A
aimed to show that emotive images will be remembered better than those that have little emotional impact on an individual.
2
Q
FMRI
A
- Functional Magnetic Resonance Imaging
- a neuroimaging procedure using MRI technology that measures brain activity by detecting changes associated with blood flow.
- used to generate images that can illustrate how the brain is working during different tasks.
3
Q
Amygdala
A
- almond-shaped set of neurons located deep in the brain’s medial temporal lobe
- plays a key role in the processings of emotions such as pleasure, fear and anger
- also responsible for determining where memories are stored in the brain and which ones are kept
4
Q
IV
A
- the intensity of the emotional arousal
- had to choose for four buttons on a scale of 0 to 3.
5
Q
DV
A
- 2 DVs
- level of atcvation of the amygdala measuredd by FMRI during the first stage of the experiement.
- 11 frames were captured per trial
- measure of memory when participants had to recognize the images 3 weeks after
6
Q
Sample
A
- 10 right-handed healthy female volunteers
- females were chosen as they are more likely to report intense emotional experiences and show more physiological reactions to the stimuli
- informed consent
7
Q
Procedure
A
- International affective picture system
- average ratings of valence ranged from 1.17(highly negative) to 5.44(neutral)
- each picture presented for a period of 2.88 seconds
- interval of 12.96 seconds
- 1.5 Tesla fMRI scanner used to measure blood-oxygen level dependant contrast.
- 96 + 48 foils
8
Q
Results
A
- emotional intensity correlated well with average ratings of emotional valence and arousal.
- average correlation coefficients between participants’ intensity ratings, on the one hand, and normative valence and arousal, on the other hand, were -0.66 and 0.68 respectively
- amydala activation correlated with higher emotional intensity
- remembered well
