BIOLOGICAL ASSUMPTIONS

Question 1

THREE ASSUMPTIONS

Answer 1

Localisation of Brain Functions
Chemical Actions in the Brain
Evolutionary Influences

Question 2

Localisation of brain Functions
(POINT)

Answer 2

Behaviour can be explained with references to specific structures in the Brain.

Question 3

Localisation of brain Functions
(EXPLAIN)

Answer 3

• Certain areas of the Brain are responsible for certain functions.
• All behaviour is produced by the operation of systems that connect specific localised regions of the Brain

Question 4

Localisation of brain Functions
(EVIDENCE)

Answer 4

Cortex: thought, language, vision and movement
Cerebellum: fine movement

Question 5

Chemical Actions in the Brain
(POINT)

Answer 5

Aspects of behaviour can be explained by the action of chemicals in the brain.

Question 6

Chemical Actions in the Brain
(EXPLAIN)

Answer 6

Neurotransmitters and Hormones are agents of communication in the nervous system.
They stimulate / inhibit the action of nerves through neurons which are linked to certain emotions and mental illnesses.

Question 7

Chemical Actions in the Brain
(EVIDENCE)

Answer 7

Melatonin: Influences wake and sleep cycles
Serotonin: Influences sleep, arousal, mood

Question 8

Evolutionary Influences
(POINT)

Answer 8

Stems from Darwin’s Natural Selection.
Behaviour can be explained with reference to Human Evolutionary History

Question 9

Evolutionary Influences
(EXPLAIN)

EEA: Environment of Evolutionary Adaptation

Answer 9

• Our behaviour is due to our Primate Inheritance and environment that have shaped our adaptation for survival.

Question 10

What is the EEA?

Answer 10

• EEA: Physical and Social conditions in the environment. Species adapts due to selective pressures at the time, results in evolutionary behaviours.

Question 11

Evolutionary Influences
(EVIDENCE)

Answer 11

We are extremely and intensely social animals who’ve developed co-operative planning skills in hostile gathering environments.

Question 12

TRUE or FALSE?
‘The biological assumption does not assume our behaviour is caused by Chemicals, Hormones, and Neurotransmitters’

Answer 12

FALSE:
Assumes that aspects of our behaviour can be explained by actions of chemicals in our brain.
Neurotransmitters and hormones are agents of communication.

Question 13

FILL THE GAP
‘All behaviour is produced by the _______ of ______ that connect specific localised regions of the Brain.’

Answer 13

All behaviour is produced by the operation of systems that connect specific localised regions of the Brain
