Kafli 7 Physiological approach

Question 1

Six examples of theories of biological underpinnings

Answer 1

Extraversion (and neuronal excitability or arousability). Sensitivity to cues of reward and punishment (based on brain circuits of the BIS and BAS systems).
Sensation seeking (and level of MAO and hormones in the bloodstream),
Tridimensional personality theory (based on neurotransmitters),
Morningness–eveningness (and circadian rhythms in body temperature).
Affective style (and hemispheric asymmetry in the frontal cortex of the brain).

Question 2

The most commonly used biological variables in personality research are :

Answer 2

Electrodermal activity, cardiovascular reactivity and brain activity.

Question 3

Examples of physiological systems are:

Answer 3

nervous system (including the brain and nerves), the cardiac system (including the heart, arteries and veins) and the musculoskeletal system (including the muscles and bones, which make all movements and behaviours possible).

Question 4

Theoretical bridge

Answer 4

The connection between two different variables (for instance, dimensions of personality and physiological variables). 154
