Biological Approach Flashcards
1
Q
Name:
The assumptions of the biological approach
A
- Behaviour is influenced by the central nervous system, genes, and neurochemistry
- Behaviour is a product of evolution
2
Q
Define:
Neurochemistry
A
- Substances naturally occuring in the brain
- enable signals to be transmitted
- imbalances associated with abnormal behaviour
3
Q
Name:
Strengths of the biological approach
A
- Children can show in/extroverted behaviour from birth
- Introverts respond less to dopamine
4
Q
Name:
Weaknesses of the biological approach
A
- Personality may be learned through reinforcement/punishment
5
Q
Define:
Genotype
A
Genetic makeup of an individual
6
Q
Define:
Phenotype
A
Observable characteristics
7
Q
Define:
SRY Gene
A
Part of the Y chromosome that causes development of male characteristics
8
Q
Name:
Strengths of the influence of genes
A
- Supports the idea of behaviour being a combination of nature + nurture
- E.G. BRCA1 gene associated with breast cancer - not all carriers will get cancer
9
Q
Name:
Weaknesses of the influence of genes
A
- Some research oversimplifies the influence of genes
10

12
Q
Serotonin
A
- controls and stabilises mood
Neurotransmitter
13
Q
Dopamine
A
- Movement, memory, pleasurable reward, motiation
- increases muscle + heart contraction force
Neurotransmitter
14
Q
Adrenaline
A
- Secreted by brain + adrenal glands
- Increases cardiac output
- Raises blood glucose levels
Neurotransmitter
15
Q
Oxytocin
A
- Triggers labour and release of breast milk
- Helps move sperm
Hormone
16
Q
Cortisol
A
- Made in adrenal glands
- Managed by pituitary gland
- Maintain blood pressure, immune function, anti-inflammatory processes
- Maintains energy levels
Hormone
17

A
- Development of male secondary sex characteristics
Hormone
18
Q

A
- Development of female secondary sex characteristics
- Regulates mensturation
Hormone
