The Cognitive Approach to explaining Depression Flashcards
The Cognitive Approach to Depression
We must refer to mental/thought processes to explain behaviour
Cognitive Approach: Key Assumptions
Thought processes can and should be studied scientifically
The mind works like a computer:
Input —> Processing —> Output
We must acknowledge the mental/thought processes that occur between a stimulus and response
what is a schema
Schema: a cognitive framework, formed through personal experience, that helps to organise and interpret information in the brain.
what did Beck say
People become depressed because the world is seen negatively through negative schemas
what is a negative schema
Negative schemas are acquired during childhood, when authority figures place unreal demands on individuals and are highly critical of them.
They are activated when a person encounters a new situation that resembles the original conditions in which these schemas were learned.
Negative schemas lead to cognitive biases, which results in distorted/faulty thought patterns.
Examples of Cognitive Biases
what is selective abstraction
Selective abstraction - conclusions drawn from an isolated detail of an event, without considering the larger context.
e.g. Someone attends a party and afterward focuses on the one awkward look directed her way and ignores the hours of smiles.
Examples of Cognitive Biases
what is overgeneralisation
Overgeneralisation - sweeping conclusions drawn on the basis of a single event.
e.g. Believing that if one public speaking event went badly that all of them will.
what is Beck’s Negative Triad
A model of the cognitive biases which are characteristic features of depression.
The triad consists of 3 elements, or pessimistic thought patterns, about:
- The Self - where individuals see themselves as being helpless, worthless and inadequate.
- The World - where obstacles are perceived within one’s environment that cannot be dealt with.
- The Future - where personal worthlessness is seen as blocking any improvements.
how is the negative triad maintained
Negative schemas, together with cognitive biases/distortions, maintain the negative triad:
Ellis’ ABC Model
Ellis believed that it is our irrational thoughts and interpretations of events that cause depression
Activating event: something happens in the environment and around you
Beliefs: You hold a belief about the event or situation
Consequence: You have an emotional response to your belief
Mustabatory ThinkingThe source of irrational beliefs
Thinking that certain ideas/assumptions must be true in order for an individual to be happy
Ellis identified the 3 most important irrational beliefs:
“I must be approved of or accepted by people I find important”
“I must do (very) well, or I am worthless”
“The world must give me happiness, or I will die”
Therapeutic success supports the cognitive approach to explaining depression.
Cognitive Behavioural Therapy (CBT) is found to be the most effective treatment for depression, especially when combined with drug treatments (Cuijpers et al., 2013).
(CBT identifies irrational and maladaptive thoughts/beliefs and restructures them into more adaptive and rational ones)
This suggests that irrational/negative thoughts have a role in causing the depression in the first place.
However, there is a cause-effect issue
The fact that there is a link between negative thoughts and depression does not mean that negative thoughts cause depression.
It may be that a depressed individual develops a negative way of thinking as a consequence of their depression i.e. the negative thoughts are a symptom of the depression.
This therefore undermines the validity of both Ellis and Beck’s cognitive explanations and suggests that there may be other causes. For example, the negative thoughts might have a biological cause e.g. low levels of serotonin.
Negative/irrational thoughts might be realistic.
Alloy & Abrahmson (1979): Depressive realists tend to see things for what they are
(with normal people tending to view the world through ‘rose-coloured spectacles’).
They found that depressed people gave more accurate estimates of the likelihood of a disaster than ‘normal’ controls – the ‘sadder, but wiser’ effect
This therefore implies that not all beliefs are ‘irrational’, although they may simply seem irrational.
