experiment van Seligman:
Experimental Setup: Dogs were placed individually in harnesses. Initially, the dogs were divided into three groups: a control group, a group subjected to escapable shocks, and a group subjected to inescapable shocks.
Escapable vs. Inescapable Shocks: In the group subjected to escapable shocks, dogs were given a warning signal (such as a sound or light) before receiving a mild electric shock. They could then learn to escape the shock by jumping over a barrier. In contrast, in the group subjected to inescapable shocks, dogs received the same shocks but had no means of escaping or avoiding them, regardless of their behavior.
Testing Phase: After this initial phase, all dogs were placed in a shuttle box—a two-compartment chamber divided by a barrier. The dogs could easily jump over the barrier to the other compartment to avoid receiving a shock if they learned that behavior.
Observations: Dogs from the control and escapable shock groups quickly learned to jump over the barrier to avoid shocks when they heard the warning signal. However, dogs from the inescapable shock group showed a different response. They initially made no attempt to escape the shock, even when there was an opportunity to do so. They seemed to have learned that their actions had no effect on the outcome of the situation.
hoe relate hij dit weer naar mensen
This behavior demonstrated what Seligman termed “learned helplessness”—a psychological condition where an individual learns to feel helpless and unable to control or influence adverse situations, even when escape or avoidance is possible.
en nu het experiment in het kort
In het learned helplessness-experiment van Seligman werden honden verdeeld in groepen die elektrische schokken kregen. Sommige honden konden de schokken vermijden door over een obstakel te springen na een waarschuwingssignaal, terwijl andere honden de schokken niet konden vermijden. De honden die geen controle hadden over het vermijden van de schokken vertoonden later in een andere situatie een hulpeloze reactie, zelfs wanneer ontsnappen mogelijk was. Dit toonde aan dat ze ‘learned helplessness’ hadden ontwikkeld, waarbij ze geloofden dat hun acties geen invloed hadden op het resultaat van een situatie.
hoe werd toen de learned helplessness theory opgezet
door dat experiment + attribution theory
wat is het idee van hoe het process gaat (deel onder conditions)
bad event + perceived uncontrollability -> helplessness -> explanatory style
waar bestaat de explanatory style uit
1) internal-external / locus
2) stable-unstable
3) global-specific
the net combination of these three dimensions led to the proposal that the emotional, motivational and cognitive deficits seen in depresion could be accounted for by a certain set of attributions following the occurerrence of a negative event.
oke
welke stijl zou een vulnerability factor zijn?
internal-stable-global attribution style for the causes of negative events and external unstable-specific attributions (e.g. “due to luck”) for positive events.
outcomes = (bovenste gedeelte figuur)
- negative affect (emotional defict)
- expectation of future uncontrollability (cognitive defect)
- passivity (motivational deficit)
outcome van internal locus
personal helplessness (low self-esteem)
waarom ga je van een internal locus naar personal helplessness en low self esteem
an internal attribution for a negative event was seen to lead to low self-esteem, especially if, by social comparison, other individuals were perceived not to be helpless in such a situation (so-called “personal helplessness”)
dus als je denkt dat jij zelf alles opfockt -> en jij alleen daarin bent -> personal helplessness -> lower self-esteem
outcome van external locus
universal helplessness (self-esteem remains the same)
outcome van stable
increased chronicity of deficits (alles blijft voor altijd kut)
outcome van global
increased generality of deficits (alles is kut)
wat was de contradiction van de learned helplessness theory
depressed individuals would blame themselves for events. but the learned helplessness theory stated that they would perceive these as controllable
wat werd er gedaan om deze contradictie op te lossen
hopelessness theory replaced it, focused only on the occurrence of negative events (not uncontrollable events or perceived uncontrollability)
the main outcome of hopelessness theory=
hopelessness, placing the emphasis on perceived negativity
wat is dan het model van hopelessness theory
bad event -> explanatory style -> hopelessness
even kijken in document naar modellen
okeeee echt doen
waar leidt internal + stable + global naar in hopelessness theory
low self-esteem
waar leidt stable + global naar in hopelessness theory
increased chronicity & generality of deficits
waar leidt hopelessness naar toe
- expectation of future uncontrollability (cognitive deficit)
- passivity (motivational deficit)
two main components of Beck’s cognitive therapy
- the types of cognitive structures that underlie emotional disorders
- the types of cognitive processes that are involved in the onset and maintenance of the disorders
cognitive therapy focuses on..
schemas & cognitive processes
schemas=
units by which memory, thinking and perception are organized. schemas are partly derived from one’s past experience but are not seen to be passive representations of these experiences. activation of part of the schema leads to activation of the whole schema: meaning that information that is not represented in the input will be filled in according to the operative “default” values.
wat zei beck over schemas
dat certain groups of dysfunctional schemas are likley to be characteristics of emotional disorders.
wat zei beck over de periode in between episodes of emotional disorders
the dysfunctional schemas are inactive and lie dormant. but they become active when the appropriate matching stressors occur.
wat voor uitleg is er voor dat deze schemas opeens actief worden
they remain active but during recovery the individual is able to inhibit the outcomes of such processing, if it is negative. or if the outcome is positive then these are consciously acceptable to the individual.
wat voor cognitieve processen gaat het om in cognitive therapy
when the dysfunctional schemas are activated they produce automatic negative thoughts. people can suppress these thoughts, but depression-prone individuals seek further evidence in support the negative thoughts and beliefs.
wat voor soort evidence seeking mechanisms hebben mensen (ook wel logical distortions)
- magnification (of negative material related to the self)
- minimization (of positive material related to the self)
- personalization (taking the blame for anything negative)
wat zijn twee punten die belangrijk zijn aan deze view of cognitive processes
- the approach implies that normal thinking is rational (which it is not)
- the approach presents a view of the self-concept in depression that is monlithic and negative, and a view of the self-concept in normal individuals that is monolithic and positive
monolythic =
(of an organization or system) large, powerful, indivisible, and slow to change.
Williams, Watts, MacLeod and Mathews: wat was hun main point
the distinction between priming and elaboration
priming =
an automatic stage of processing in which the stimulus may be linked with its representation in long-term memory
elaboration =
subsequent strategic or resource demanding processes
Elaboration verwijst naar het proces waarbij mensen nieuwe informatie begrijpen en onthouden door deze te koppelen aan bestaande kennis of ervaringen.
wat zeiden ze over priming & elaboration in anxiety
Williams, Watts, MacLeod and Mathews
automatic priming processes are biased towards the detection of anxiety-relevant stimuli or situations.
however, although initial priming or automatic processes are biased towards the detection of threat in anxiety, subsequent elaborative processes are biased away from the processing of threat.
dus meer threat detection, minder threat elaboration nadat het is gedetect
wat zeiden ze over priming & elaboration in depressie
Williams, Watts, MacLeod and Mathews
the main cognitive biases evident in depression are resource-demanding elaborative ones, that are most apparent in mnemonic tasks.
dus in depression is de bias bij priming niet perse aangetast, maar het gaat hier meer om dat er heel veel resource demaning elaborative processes biased zijn.
strengths of Williams, Watts, MacLeod and Mathews theory
it provided a focus for the dissatisfacton felt by many researchers with the predictions for global cognitive biases that emerged from the theories of Beck and Bower
