4.2.1 biological approach

Question 1

biological approach

Answer 1

examines the processes that occur and looks for how that may affect an individual

Question 2

basic assumptions

Answer 2

behaviour is affected by:

1. genetics- genes an individual influences their behaviours.
2. CNS- brain is seen as the main focus of explaining behaviour as its seen as the origin of how the world is seen
3. chemistry of the body

Question 3

genotype

Answer 3

genetic make up of an individual and provides the genetic code for how that individual will develop
dictates characteristics such as eye and natural hair colour

Question 4

phenotype

Answer 4

product of what happens when the genotype interacts with the environment

Question 5

biological structures- nervous system

Answer 5

divided into 2 structures- peripheral and central

Question 6

central nervous system

Answer 6

consists of the brain and the spinal chord
pivotal in transferring messages to and from the environment
act as the centre from which all of the physiology of the individual is controlled

Question 7

peripheral nervous system

Answer 7

sends and receives information to the central nervous system
nervous system for limbs and torso which collect information from the environment in terms of temperature, pain and threat.
has 2 parts to it- autonomic and somatic

Question 8

autonomic nervous system

Answer 8

important for survival of the individual and affects the reaction to threat, along with returning the body to normal after an acute reaction

Question 9

somatic system

Answer 9

comprises the muscles attached to the skeleton and is therefore very important in movement

Question 10

neurochemistry

Answer 10

the biochemistry of the central nervous system
