Q

The acceptance of the biological model encourages researchers to

A

seek a physical basis for disorders, leads to the formulation of a diagnostic system that classifies people as disordered and implies that physical interventions should be the treatments of choice.

Q

single factor explanation

A
  • genetic defect or a single traumatic experience causes a mental disorder
  • attempts to trace the origins of a particular disorder to on factor
  • reflects the primary focus of the researcher rather than the belief of there being only one cause

Q

interactionist explanations

A

view behaviour as the product of the interaction of a variety of factors, generally make more satisfactory theories in describing mental disorders. as knowledge of any single disorder increases, so, characteristically, does the complexity of theories offered to account for its development and maintenance. takes into account all elements of the individual, acknowledging that one component inevitably affects the other components

Q

Theories may also be classified according to their level of explanation.

A

some theories try to explain:

  • all human behaviour
  • all abnormal behaviour
  • all disorders within a particular category
  • causes to a particular problem
  • elucidate the influence of a single factor within a more general theory

Q

single factor theory: scientific theories are judged to be valued not because they describe the enduring truth about an issues, but rather because they embody three essential features:

A
  1. they integrate most of what is currently known about the phenomena in the simplest way possible (parsimony)
  2. they make testable predictions about aspects of the phenomena that were not previously thought of
  3. They make is possible to specify what evidence would deny the theory

Q

the general aims of theories about mental disorders are to:

A
  1. explain the etiology of the problem or behaviour
  2. identify the factors that maintain the behaviour
  3. predict the course of the disorder
  4. design effective treatments

Q

External factors can effect biological functioning- Aaron T Beck’s cognitive formulation of depression and anxiety

A

cognitive therapy can not only alter an individual’s cognitive processes in order to reduce symptoms of depression and anxiety but also affect his or her neurobiology . depressive and anxious symptoms result from the activation of negative schemas or core beliefs and negative emotions which are associated with the increased activation in the amygdalohippocampal subcortical region fo the brain. they are also associated with restricted access to reflective processes or cognitive control associated with the anterior cingulated cortex, medial and lateral prefrontal cortex and orbitofrontal cortex. CT directly seeks to reduce symptoms by modifying maladaptive thoughts, attitudes, and beliefs as well as information processing biases and reduces activation of the amygdalohippocampal and increased the activation of the other brain regions listed above

A
  1. biological
  2. psychodynamic (derived from the theories of freud or his followers)
  3. behavioural or cognitives- behavioural based theories
  4. cognitive theories examining dysfunctional thoughts or beliefs

A
  • male adult has over 86 billion neurons and equal number of glial cells
  • brain activity associated with particular functions as the product of interactions among neuronal networks that produce domain-general functions, rather than due to activity located within one single area of the brain

Q

neurotransmitters

A

are the chemical substance that carry the messages from one neuron to the next in the complex pathways of nervous activity within the brain. (either activate or inhibit) there are gaps call synapse between the axons (which carry the nerve impulse to the synapse) of one neuron and the dendrites (which pick up the activity from the first neuron) of neighbouring neurons

35
Q

synaptic cleft

A

deactivate neurotransmitters, so some neurotransmitters are destroyed before they reach the dendrites

36
Q

reuptake of neurotransmitters

A

-drawn back into the releasing axon.
This abnormal behaviour can result from disturbances in neurotransmitter systems in various ways:
1. there may be too much or too little of the neurotransmitter produced or released into the synapse
2. there may be too few or too many receptors on the dendrites
3. there may be an excess or a deficit in the amount of the transmitter-deactivating substance in the synapse
4. the re-uptake process may be too rapid or too slow

37
Q

schizophrenia

A

-too much dopamine, drugs used to decrease activity in the dopaminergic system

38
Q

brain plasticity

A

capacity of the brain to reorganize its circuitry
-influenced by a number of experiences that occur pre and postnatally through hormones, diet, aging, stress, disease and maturation

39
Q

Dr. Bryan Kolb experiment.

A

the off spring of rats that were raised in a complex environment exhibited increased synaptic space on the neurons in their cerebral cortex. virtually an manipulation that produces an enduring change in behaviour leaves and anatomical footprint in the brain

40
Q

peripheral nervous system

A

includes the somatic nervous system, which controls the muscles and the autonomic nervous system

41
Q

ANS

A
  1. the sympathetic nervous system
  2. the parasympathetic nervous system

work together to perform homeostatic (balanced) activity in a variety of bodily functions (ex. heart rate, digestive and eliminatory processes, sexual, breathing

42
Q

Hans selye

A

studied responses to stress
-individuals differ in both the strength and the duration of their response to threat and this variability has been related to the person’s propensity to develop psychophysiological disorders

43
Q

ANS more particularly the sympathetic nervous system is involved with

A

fear and anxiety reactions

-thus an overreactive ANS may produce more phobias etc..

44
Q

endocrine system

A

aspects of the CNS interact with the endocrine system in a feedback loop that maintains appropriate levels of hormones circulating in the bloodstream.

45
Q

two disorders are known to be related to malfunctioning endocrine glands

A

cretinism- a disorder involving a dwarf-like appearance and intellectual deficits is a result of defective thyroid gland
hypoglycmiea, which results from the pancreas failing to produce balanced levels of insulting or glycogen (produces experiences that mimic anxiety

46
Q

hypothalamic-pituitary-adrenal (HPA) axis

A
  • depression and anxiety
  • the hpa axis is activated in response to stressors and involves an intricate system of communication among the hypothalamus, the pituitary gland and the adrenal cortex.
  • important action involve the release of the stress hormone cortisol into the bloodstream by the adrenal cortex. this hormone facilitates an individuals response to short-term threat by producing a number of change in the body
47
Q

Biological determinism

A

what a person is is determined largely by inherited characteristics

48
Q

Thomas Hobbes

A

thought that aggression and self-interest were inborn features of all humans and that it was the business of political systems to restrain and usefully channel these impulses

49
Q

by the 19th century it was believed that all people took their ______ allotted place in society

A

biologically
- that is, the destitute were condemned by their inherited characteristics to be poor, whereas the wealthy and the aristocracy were simply displaying their hereditary advantages

50
Q

cesare lombroso

A

declared that criminals could be identified by the psychological features they had inherited from their degenerate parents

51
Q

paul broca

A

claimed that males were born with brains superior to those of females

52
Q

behavioural genetics

A

offer us an insight into the biological bases of abnormal functioning

53
Q

psychopathology

A

genes confer a liability not a certainty

54
Q

gene-environment (genotype environment) interaction

A

genes may influence behaviours that contribute to environmental stressors, which, in turn, increase the risk of psychopathology

55
Q

behavioural research into the genetic bases of psychiatric disorders typically takes one of three forms

A

family (or pedigree)
twin
of adoption studies

56
Q

concordant

A

to display concordance for the problem
-the degree of concordance is though to reveal the influence of genetics. although not always accurate because concordance can reveal environmental influences, depending on the circumstances

57
Q

genetic linkage studies

A

researchers examine families that have a high incidence of a particular psychiatric disorder. within these extended families, researchers look for the presence of particular traits called genetic markers that can be linked to the occurrence of the disorder

58
Q

molecular biology

A

compare specific DNA segments and identify the genes that determine individual characteristics. can pinpoint the defective genes that contribute to various medical and psychological disorders

59
Q

psychodynamic theorists

A

suggested that behaviour is motivated by unconscious processes acquired during the formative years of life

60
Q

behaviours are learned responses to environmental stimuli

A

-behavioural, cognitive-behavioural and social learning theorists

61
Q

the way people people think about or perceive their world causes them to develop disorders

A

cognitive theorists

62
Q

personal experience provides the basis for the development for the development of self directed behaviour

A

humanists and existentialists

63
Q

the surrounding society of culture exerts powerful influences on people; that such influences may cause disorders to occur and moreover that a particular society may define a person as abnormal because it suits the ends of that society

A

socio-cultural theorists

64
Q

psychodynamic theories

A

sigmund freud

  • unconscious forces of which the person is unaware control behaviour
  • see the person as having control over their actions
65
Q

catharsis

A

discharging the emotional responses attached to these unconscious memories by identifying the original traumatic experience during hypnosis

66
Q

in feuds theory, four features together determine current behaviour and thinking, both abnormal and normal:

A
  1. different levels of consciousness determine the accessibility of thoughts and desires
  2. the structures of personality represent the embodiment of the various controlling forces
  3. the stages of psychosexual development indicate the points in experience where problems can arise
  4. defence mechanisms are the means by which people channel their psychic energy in functional or dysfunctional ways
67
Q

three levels of consciousness

A

conscious, preconscious, unconscious

68
Q

conscious

A

contains information of which we are currently aware

69
Q

preconscious

A

holds information not presently within out awareness ut that can readily be brought into awareness

70
Q

unconscious

A

(most important according to freud)
contains the majority of our memories and drives that that, unfortunately can only be raised to awareness with great difficulty and typically only in response to particular techniques (that is by psychoanalytic procedures)

71
Q

defence mechanisms

A

the unacceptable drives and the traumatic memories were kept out of awareness by defence mechanisms
-the ego uses defence mechanisms (the weaker the ego, the less resolved the individuals psychosexual stages) the greater the conflict and thereby the greater the exhaustion of psychic energy

72
Q

structures of personaility

A

three structures of personality are in constant conflict

id, ego and superego

73
Q

id

A

structure present at birth and it contains or represents the biological or instinctual drives. these drives demand instant gratification without concern for the consequences either to the self or to others (pleasure principle)

74
Q

ego

A

develops in the first year of life

  • develops to curb the desires of the id so that the individual does not suffer any unpleasant consequences
  • no right or wrong, only avoiding pain or discomfort and the maximization of unpunished pleasure (reality principle)
75
Q

superego

A

as the child gets older the superego develops.

  • the internalization of the moral standards of society inculcated by the child’s parents (moral principle)
  • serves as persons conscious monitoring the ego
  • there more strongly developed the ego, the better able it is to handles the often opposing pressures
76
Q

psychosexual stages of development

A

sexual drives were the most important determinants of behaviour and even the most innocent actions might be driven by sexual drivers.
-phallic stage

77
Q

eros

A

the energy for which was libido

78
Q

erogenous zones

A

sexual pleasure or the expression of libidinal energy was focused on different body parts, and the focus of these zones differed at different stages of psychosexual development.
failure to resolve a stage would result in a fixation on the erogenous zone associated with that stage

79
Q

phallic stage

A

boys are presumed to develop sexual desires for their mother and girls are thought to desire their fathers, not to win their father’s love but rather by seducing him to gain what they truly desire: a penis

80
Q

oedipal complex

A

boys see their father as a competitor for their mother’s love

81
Q

castration anxiety

A

the fear that boys father will mutilate genitals

82
Q

electra complex

A

girls desire for their father

83
Q

insight

A

the patient’s acceptance of the analyst’s account of the origin of the problem

84
Q

behavioural theorists

A

conditioning accounts: john b watson

-all human behaviour is learned

85
Q

classical conditioning

A

the basis for learning: ivan pavlov

86
Q

stimulus-stimulus learning

A

what is learned in classical conditioning, then, is the transfer of a response from one stimulus to another
-conditioned responses can instill phobic responses
