Q

Define identification

A

When an observer associates themselves with a role model and wants to be like the role model. They are more likely to imitate role models they identify with.

33
Q

How does schema affect the cognitive approach?

A

As beliefs and expectations effect thoughts and behaviours (innate of learnt)
Mental short cut, leads to perceptual errors.

34
Q

How are theoretical and computer models used to study internal mental processes?

A

Mind is likened to a computer and applied to artificial intelligence

35
Q

Define cognitive neuroscience

A

The scientific study of biological structures that underpin cognitive processes

36
Q

How does cognitive neuroscience aid the study of internal mental processes?

A

Brain imaging (PET, MRI, etc)

Helped us understand different biological structures link to mental states

37
Q

Advantage of research into the cognitive approach?

A

Scientific and objective

Lab experiments produce reliable data

38
Q

Disadvantage of using computer models to study the mind?

A

Machine reductionism- ignores the influence of emotion eg. Anxiety

39
Q

Disadvantage of the cognitive approach?

A

Abstract and overly theoretical- lack external validity

40
Q

Define the biological approach

A

Everything psychological is at first biological

41
Q

What is the assumption of the biological approach?

A

Biological processes: genes, neurochemistry, and the nervous system

42
Q

What is a genotype?

A

Particular set of genes that a person possesses

43
Q

What is a phenotype?

A

The characteristics of a individual determined by both genes and the environment

44
Q

How are twin studies used to investigate the biological approach? (Explain some results)

A

Used to determine the likelihood that certain traits have a genetic basis by comparing concordance rates between pairs of twins.

Monozygotic (identical) = higher concordance on music ability

Dizygotic (non identical) = lower concordance on music ability

45
Q

What does the interaction between phenotype and genotype show?

A

The interaction between nature (inherited factors) and nurture (environment)

46
Q

How does evolution link to the biological approach?

A

Natural selection of genes based on survival value and ultimately reproductive success

47
Q

Does the biological approach have a real life approach?

A

Yes in psychotherapeutic drugs (for depression etc)

48
Q

Limitation of the biological approach?

A

Drugs may only be associated with symptom reduction not the causes. (Neurotransmitters)

49
Q

Advantage of the biological approach?

A

Based on precise techniques and reliable data (twin studies etc)

50
Q

What 2 nervous systems make up the human nervous system?

A

Peripheral NS & Central NS

51
Q

What makes up the peripheral NS?

A

Autonomic NS & Somatic NS

52
Q

What makes up the central NS?

A

Brain & Spinal Cord

53
Q

What makes up Autonomic NS?

A

Sympathetic NS & Parasympathetic NS

54
Q

What does the Peripheral NS do?

A

Sends info to the CNS from the outside world, and transmits messages from the CNS to muscles and glands in the body.

55
Q

What does the Somatic NS do?

A

Transmits info from receptor cells in the sense organs to the CNS. It also receives information from the CNS that directs muscles to act.

56
Q

What does the Autonomic NS do?

A

Transmits info to and from internal bodily organs. It is ‘autonomic’ as the system operates involuntarily (it is automatic). It has two main divisions: the sympathetic and parasympathetic nervous system.

57
Q

How many hemispheres are there in the brain?

A

2

58
Q

What makes up the endocrine system?

A

Glands and hormones

59
Q

Which gland is the master gland?

A

The pituitary gland (in the brain)

60
Q

How are hormones distributed?

A

In the bloodstrem

61
Q

What is a gland?

A

An organ which synthesises substances such as hormones

62
Q

What are hormones?

A

Chemical substances that circulate in the bloodstream and only affect target organs. They are produced in large quantities but disappear quickly. They have a very powerful effect.

63
Q

What is adrenaline?

A

A hormone produced by the adrenal glands which is part of the human body’s immediate stress response system.

Adrenaline has a stimulating effect on the body eg. Heart rate

64
Q

How does fight or flight work? (Explain the steps)

A

Stressor perceived

Hypothalamus triggers activity in sympathetic branch in ANS.

Stress hormone adrenaline is released from adrenal medulla (part of the adrenal gland) into the bloodstream.

This triggers physiological arousal needed for fight or flight response

(This all happens in an instant)

65
Q

How does the body change from the fight or flight response back to normal.

A

Parasympathetic works in opposition to the sympathetic NS

(Rest and digest response)

66
Q

List the three types of neuron?

A

Motor, sensory, and relay

67
Q

What does a sensory neurone do?

A

Carry messages from the PNS to the CNS. They have long dendrites and short axons

68
Q

What does a relay neurone do?

A

Connect sensory neurones to the motor or other relay neurones. They have short dendrites and short axons.

69
Q

What do motor neurones do?

A

Connect CNS to effectors such as muscles and glands. They have short dendrites and long axons.

70
Q

Who’s are axon divided?

A

By nodes of ranvier

71
Q

What are axon covered in?

A

Myelin sheath

72
Q

What does the cell body contain?

A

Nucleus

73
Q

Where are the terminal buttons?

A

At the end of axon

74
Q

How is action potential caused?

A

When a neurone is activated by a stimulus, inside of the cell becomes positively charged for a split second causing an action potential to occur.

75
Q

What does an action potential cause?

A

An electrical impulse that travels down the axon towards the end of the neurone.

76
Q

What is a neurotransmitter?

A

Brain chemicals releases from synaptic vesicles that relay signals across the synapse from one neurone to another.

77
Q

What is excitation?

A

When a neurotransmitter, such as adrenaline, increases the positive charge of the post synaptic neurone. This increases the likelihood that the neurone will fire and pass on the electrical impulse.

78
Q

What is inhibition?

A

When a neurotransmitter, such as serotonin, increases negative charge of the postsynaptic neurone will fire and pass on the electrical impulse.

79
Q

What is the synapses role in synaptic transmission?

A

Terminal buttons at synapse, presynaptic vesicles release neurotransmitters

80
Q

Explain summatation

A

If the net effect is excitatory neurone is more likely to fire
