Week 4 Flashcards
What is the focus of CBTp?
Achieving an alternative interpretation of the positive symptoms experienced during the schizophrenia. Usually, CBT aims at reducing symptoms but this is hard in schizophrenia.
What is food reactivity?
Food reactivity refers to the response that individuals experience when being presented with food cues. For example, the strength of a dopamine release when seeing French fries.
Food cue reactivity is significantly stronger in individuals who struggle with overeating. While it is easily learnt and generalized, extinction proves to be more troublesome.
How can we help people with a high food cue reactivity?
Their reaction is based on contextual cues that have predictive power for the occurrence of eating. Through exposure and response prevention we can help to lessen the predictive value of the CS.
Yet, the common problems with exposure therapy hold valid. It needs to be across multiple contexts to prevent renewal and it easily comes back according to inhibitory learning.
What is reinstatment?
When you are being exposed to the US after the association has been extinguished this might strengthen the association again. For example, you ate chips again (US) and this strengthens your food cue reactivity the next time you watch a movie (CS).
How may occasional reinforcement help with dieting?
When during your restriction, you occasionally pair the CS with the US, followed by restriction again, then you come to associate a lapse in your diet with continuation rather than with throwing the whole thing away.
In this way, extinction trials are more generalized and a lapse does not predict a regression.
