What is the Biological approach?
The biological/physiological approach is the scientific study of biological and physiological
processes in the body and how this affects the behaviour

Emotions, behaviours and cognition…

 Are controlled by biological systems and processes such as evolution, genes (DNA),
nervous system and hormones.

 Can be investigated by manipulating and measuring biological responses, such as eye
movement, brain activity and pulse rate.

, CANLI et al. 2000
Event-related activation in the human amygdala associates with
later memory for individual emotional experience

Aim:

- Showing that emotive images will be remembered better than those that have little
emotional impact on an individual.
- Whether the amygdala is sensitive to varying degrees of emotional intensity on external
stimuli and whether the level in intensity enhances memory for the stimuli

Research methods:

- Lab experiment
- FMRI (functional magnetic resonance imagery) scanner used
- IV level of perceived emotional arousal of 96 different scene rating from 0 (not
emotionally intense) to 3 (very emotionally intense)
- DV FMRI measure of amygdala activation and memory of scene
- Repeated measures design

Sample:

10 right handed healthy women. Women chosen as they are more likely to report intense
emotional experiences.

Voluntary sampling

Procedure:

- P’s where asked for informed consent therefore no deception
- 96 images where presented through a mirror allowing the participant to see whilst lying,
not biasing the FMRI with movement)
- Valence ratings of these images ranged from 1.17(highly negative) to 5.44 (neutral)
- Order of the pictures was random for each p’s to avoid order effects (comparation of
emotive images)
- Each picture was presented for 2.88 seconds. With and interval of 12.96 seconds
- Once the picture presented, the p’s indicated the emotional arousal experience with their
right hand (0-3)
- The scale rating was contrasted with the FMRI amygdala activation
