Biological approach - genes & neurochemistry

Which of these is NOT an assumption of the Biological Approach

• Behaviour cannot be understood without considering internal mental processes

• Physical structures determine how we behave

• Following Darwin's theory of evolution, much behaviour will have a genetic basis

• Psychology should investigate the nervous system, endocrine system and neurochemistry

How do genes affect behaviour? Tick all that apply.

• They control how our thoughts are developed.

• They control the biochemicals we produce e.g. hormones

• They develop our sense of self

• We inherit behaviours through inheriting the genes that control them.

An individual's genetic make-up, their DNA is called what?

• Prototype

• Phenotype

• Genotype

• Stereotype

Foetal alcohol syndrome is a developmental disorder resulting from exposure to alcohol by a genetically healthy foetus in the uterus. This is an example of what?

• A genotype

• Genetic inheritance

• concordance levels

• A phenotype

What are MZ twins

• Non-identical twins that are the same sex

• Non-identical twins that share 50% of their genes

• Identical twins that share 100% of their genes

• Identical twins that share 50% of their genes.

What are DZ twins

• Non-identical twins that are the same sex

• Non-identical twins that share 50% of their genes

• Identical twins that share 100% of their genes

• Identical twins that share 50% of their genes.

Which two from the following are not true.

• Neurotransmitters are chemical messengers that circulate in the bloodstream

• Neurotransmitters are chemical messengers that work at the synapse

• Neurotransmitters work within the nervous system.

• Neurotransmitters work within the endocrine system.

Which two of the following are not true

• Hormones are chemical messengers that travel in the bloodstream

• Hormones are chemical messengers that work at synapses

• Hormones work as part of the endocrine system

• Hormones work as part of the nervous system

Choose the two correct statements about 'fight or flight'

• It is a rapid, short term stress response triggered by activation of the parasympathetic NS.

• It is the body's long term response to a stressful event using cortisol.

• It is a rapid, short term stress response using adrenaline to increase heart and breathing rate.

• It is an evolved response to the perception of a threat or stress using the Autonomic Nervous system.

What other role does adrenaline have during the stress response.

• Releasing stored glucose from the liver

• Causes the pupils to contract

• Increases activity of the digestive system

• Stops the body from sweating to conserve energy
