Define statistical frequency

A

A person would be considered abnormal if they were found to be numerically rare. What is regarded as rare depends on normal distribution, anyone else is abnormal (5% of population, 2 standard deviations)

5) accurate perception of reality= Having an objective and realistic view of the world
6) Mastery of the environment= being competent in all aspects of life and being able to meet demands of any situations

Q

What is the 2 process model - Mowrer (1947)?

A
  • Describes the combination of both conditioning types (classic + operant)
  • The 2 process model assumes phobias result from learning
  • Patients must have associated something neutral with a traumatic consequence
  • Strengthened through -ve reinforcement
17
Q

How can SLT create a phobia

A

Children see their parents being scared of something and identify and imitate with them,

Also vicarious reinforcement as see parents happy after avoiding it so also want to feel that

18
Q

What is flooding?

A

Sudden exposure of the patient to the stimulus, until the anxiety is extinguished.

19
Q

Define counterconditioning

A

Learning a new response to a phobia (relaxation instead of anxiety)

20
Q

Define reciprocal inhibition

A

The idea that you cannot feel afraid and relaxed at the same time, meaning 1 emotion prevents the other.

21
Q

What is systematic desensitisation

A

1) Agreeing a hierarchy
2) Teach relaxation techniques
3) Gradual exposure to feared stimulus using hierarchy

Reciprocal inhibition occurs
Causes counterconditioning

22
Q

What alternative treatments are there for phobias?

A

Drugs e.g. BZ’s

They have unpleasant side effects like feeling lethargic, can’t concentrate, sleeping

23
Q

What are the emotional characteristics of depression?

A

Avolition (low motivation)
Helpless/hopeless (Isolated)
Anhedonia (feeling emotionally numb)

24
Q

What are the cognitive characteristics of depression?

A

Catastrophise
Ruminate
Suicidal ideation

25
Q

What are the behavioural characteristics of depression?

A

Self harm
Insomnia/hypersomnia
Change in appetite
Avoidance

26
Q

What is depression?

A

What is a mood disorder, characterised by low mood and low energy levels. Caused by irrational thinking

27
Q

What is Ellis’ ABC model (1962)?

A

Irrational beliefs are due to musturbatory thinking.
Musturbatory thinking= thinking that certain ideas must be true for someone to be happy

Normal thinking= Activating event -> rational belief -> consequence

Depressed thinking= irrational belief instead of rational belief

28
Q

What is Beck’s negative triad (1967)?

A

Perception of self, perception of world and perception of future are all linked. Negative thinking leads to negative triad.

29
Q

What is CBT?

A

CBT is a talking therapy that aims to identify irrational core beliefs and uses practical activities to challenge and change them.

CBT assists patients to identify irrational thoughts and change them.

As behaviour is seen as being generated by thinking, the most logical and effective way of changing maladaptive behaviour is to change the irrational thinking underlying it.

Therefore CBT involves cognitive and behavioural elements. Cognitive- identifying and challenging irrational thoughts. behavioural- once cognitive part is done, coping strategies are developed.

30
Q

What is Ellis’ REBT?

A

Her ABC was extended to include D,E and F.
D_isputing irrational cognitions
E_ffects of disputing/effective attitudes
F_eelings that result from the process

  • aim to identify core beliefs
  • dispute the irrational cognitions
  • discuss and rationalise emotions
31
Q

What are the principles of CBT?

A

Homework- set patients tasks between sessions to challenge irrational beliefs, they must be accessible and agreed.

Behavioural activation- activity is physiologically and psychologically rewarding.

unconditional positive regard (UPR)- patients who feel valued and trusted are more motivated

32
Q

What are the genetic explanation in explaining OCD?

A

COMT gene: may contribute to OCD. (catechol-o-mehtyl transferase (COMT) regulates the production of dopamine that has been implicated in OCD. An allele of the COMT gene has been common in OCD patients. this variation lowers activity of COMT gene and higher levels of dopamine.

SERT gene: 5-HTT (SERT) affects the transport of serotonin, creating lower levels of it

33
Q

Define diathesis stress?

A

There is not one specific gene that causes OCD. Each gene creates a vulnerability ( a diathesis) for OCD. Other factors (stressors) affect what condition develops.

34
Q

Define concordance rate

A

Measure of genetic similarity

35
Q

What are the neural explanations in explaining OCD?

A

Abnormal levels of neurotransmitters- dopamine is too high and serotonin is too low.

Abnormal brain circuits- The caudate nucleus (located is basal ganglia) normally suppresses signals from orbirtofrontal cortex (OFC). OFC sends signals to thalamus about what to worry about. When the caudate nucleus is damaged it fails to suppress OFC- creating a worry circuit.

36
Q

What do SSRIs do?

A

Most commonly used drug for OCD and depression. Selective serotonin re-uptake inhibitors (SSRIs) are the preferred drug for treating anxiety disorders. They increase serotonin levels.

Serotonin is released into a synapse from one neuron. it targets receptor cells on the receiving neuron and afterwards is reabsorbed by the initial neuron. The SSRI inhibits the re-uptake.

37
Q

What do tricyclics do?

A

Block the transporter mechanism that re-absorbs both serotonin and noradrenaline into the pre-synaptic cell after it has fired. prolonging activity and easing transmission of next impulse.

  • target more than one neurotransmitter
  • used as second line treatment after SSRIs due to nasty side effects.
38
Q

What do benzodiazepines (BZs) do?

A

Commonly used to reduce anxiety. they are manufactured under various names (e.g. xanax) they slow down the activity of the CNS by enhancing GABA, which quiets brain neurons.

Does this by reacting with GABA receptors on the outside of receiving neurons. When GABA locks into receptors it opens a channel that increases flow of chloride ions into the neuron (chloride makes it harder for it to be stimulated by other neurotransmitters) making person feel more relaxed)

39
Q

What does D- cycloserine do?

A

Enhances transmission of GABA
