25
What do axons do?
Carry the nerve impulse to the dendrites
26
What do dendrites do?
Pick up the activity from the neighbouring neurons
27
What can result from neurotransmitter imbalances in the brain?
abnormal behaviour
28
Hormones

29
Abnormalities in the structure or number of chromosomes are associated with what?
Malfunctions and disorders eg. down syndrome
30
Genotype
a person's total genetic endowment
31
Phenotype
the observed structural and functional characteristics
32
Passive effect
a genotype-environment correlation resulting from the genetic similarity of parents and children
33
Evocative effect
a genotype-environment correlation where a child's phenotype evokes particular kinds of reactions from the social and physical environment
34
Active effect
a genotype-environment correlation where a child seeks out or builds an environment that is congenial
35
Genotype-environment interaction
refers to the fact that genes may influence behaviours that contribute to environmental stressors, which, in turn, increase the risk of psychopathology
36
How do genetic influences operate in terms of mental disorders?
Polygenetically ie. through the action of many genes together in an additive or interactive fashion
37
What are the three traditionally used methods in studying behaviour genetics?
1. The family history method 2. The twin method 3. The adoption method
38
Concordance
When another family member displays the same disorder as the index case (person being studied)
39
Psychodynamic viewpoint
4 features control behaviour/thinking: (via Freud) 1. Levels of consciousness 2. Structures of personality 3. Stages of psychosexual development 4. Defense mechanisms
40
What are the levels of consciousness in the psychodynamic viewpoint?
Conscious - information in our current awareness Unconscious - primary, behaviour-driving eg. hunger Preconscious - Information that is not in awareness but can be brought into it
41
What are the structures of personality in the psychodynamic viewpoint?
Id Ego Superego
42
Id
source of instinctual drives
43
Ego
mediates the demands of the id and the realities of the external world
44
Superego
outgrowth of internalizing the taboos and moral values of society
45
How does the Ego deal with neurotic or moral anxiety?
By resorting to irrational protective measures. ie. ego-defense mechanisms
46
Ego-defense mechanism: Repression
burying in the unconscious the unacceptable impulses of the id
47
Ego-defense mechanism: Regression
employing behaviors typical of an earlier stage of development
48
Ego-defense mechanism: Projection
attributing one's own desires to others
49
Ego-defense mechanism: Intellectualization
hiding the real issues behind a screen of abstract analyses
50
Ego-defense mechanism: Denial
refusal to acknowledge an unpleasant reality
51
Ego-defense mechanism: Displacement
the transfer of feelings from one person to another, less threatening person
52
Ego-defense mechanism: Reaction formation
repressing unacceptable desires by expressing the opposite viewpoint
53
Ego-defense mechanism: Sublimation
transformation of sexual or aggressive energy into some more acceptable activity
54
What are the stages of psychosexual development?
``` Oral (0-2 yrs) Anal (2-3 yrs) Phallic (2-6 yrs) Latency (6-12 yrs) Genital (puberty and beyond) ```
55
How did Freud connect the psychosexual phases to abnormal behaviour?
He believed that life events could cause someone to get 'stuck' at a particular stage, which came out in their behavior
56
Oedipus/Electra complex
When a child resents same-sex parent and developed an unhealthy attachment to the the other gender parent. Results from being 'stuck' at Phallic stage
57
What is the Behavioural Perspective?
The idea that behaviour can be learned and changed through the process of classical conditioning
58
Unconditioned Stimulus
a stimulus that elicits and unlearned response
59
Unconditioned Response
an unlearned response
60
Conditioned Stimulus
a previously neutral stimulus that evokes a conditioned response after repeated pairings with an unconditioned stimulus that had previously evoked that response
61
Conditioned Response
a learned response to a previously neutral stimulus
62
Classical conditioning
a form of learning in which a response to one stimulus can be made to occur to another stimulus by pairing or associating the two stimuli
63
Operant conditioning
a form of learning in which behaviour is acquired and strengthened when it is reinforced
64
Reinforcement
changes in the environment (stimuli) that increase the frequency of the preceding behavior
65
Positive reinforcers
reinforcers that, when introduced, increase the frequency of the preceding behavior
66
Negative reinforcers
reinforcers that, when removed, increase the frequency of the preceding behavior
67
Punishment
application of aversive or painful stimuli that reduces the frequency of the behaviour it follows
68
Generalization
when a response is conditioned to one stimulus it can be evoked by other similar stimuli
69
Discrimination
when a person learns to distinguish between similar stimuli
70
Social Learning Theory
a learning-based theory that emphasizes observational learning and incorporates roles for cognitive variables in determining behavior
71
Modeling
learning by observing and imitating the behaviours of others
72
Expectancies
beliefs about expected outcomes
73
What is the basis of Cognitive Models of study?
That our interpretations of events is what determines our response, emotional state and if it devolves into abnormal behaviour. ( as opposed to the actual events)
74
Who used the 'ABC approach' to explain the causes of misery?
Albert Ellis - prominent cognitive theorist
75
What is the 'ABC approach'?
A - Activating event B - Beliefs C - Consequences The relationship between A and C depends on B
76
Rational Emotive Behavior Therapy (REBT)
a therapeutic approach that focuses on helping clients replace irrational, maladaptive beliefs with alternative, more adaptive beliefs
77
Schema
an underlying representation of knowledge that guides the current processing of information
78
What does Aaron Beck believe is the cause of depression?
'cognitive distortions' (ie. errors in thinking) - interpreting events in a negative light
79
Cognitive Therapy
a therapeutic approach that encourages clients to recognize and change their cognitive distortions
80
Cognitive - Behavioural Perspective
a perspective that focuses on how thoughts and information processing can become distorted and then result in maladaptive emotions/behavior
81
Humanistic Model: Abraham Maslow
people behave dysfunctionally as a result of experience that diverts them from self-actualization
82
Humanistic Model: Carl Rogers
abnormal behaviour results form a distorted view of self which comes from an inability to trust experience
83
Self-actualization
the tendency to strive to become 'all that you can be.' The motive that pushes one to reach full potential and express unique capabilities
84
What are the levels of Maslow's hierarchy of needs?
``` Physiological Safety Love/Belonging Esteem Self-actualization ```
85
What is the focus of Humanistic Therapies?
The clients subjective, conscious experiences | The present, here and now
86
Person-centered therapy
a therapeutic approach that uses a warm, accepting therapeutic relationship to encourage a client to engage in self-exploration and achieve self-acceptance. Non directive, extensive use of reflection
87
Psychosocial Causal Factors
developmental influences that may handicap a person psychologically
88
What are some psychosocial causal factors?
Early deprivation or trauma Inadequate parenting styles Marital discord/divorce Maladaptive relationships
89
Sociocultural viewpoint
A viewpoint that sees the social environment as a source of either vulnerability or resistance to mental disorder
90
Sociocultural Causal Factors
sociocultural factors that are associated with a greater risk of various disorders
91
What are some examples of sociocultural causal factors?
``` Low SES Unemployment Subjection to prejudice/discrimination Social change/uncertainty Gender Social support levels ```
92
Biopsychosocial Perspective
a perspective that examines the contributions of multiple factors representing biological, psychological, and sociocultural domains as well as their interactions, in the development of psychological disorders
