Objective: Assessment of the practicability and acceptance of a guide, which was created based on the Dialectic Behavioral Therapy (DBT) regarding interactions, attitudes and basically overarching therapeutic interventions (GiMa-Therapy-Basics, GMTB) METHODS: Written survey of clinic staff (n = 83) from different professions as experts based on training and experienced in using the guide.
Results: Experts reported a high user acceptance. The applicability in psychiatry was estimated as high across psychiatric disorders.
Article Synopsis
- * Participants first learned to associate a cue with a result in a specific context (context AB), then went through extinction training in a different context (context CD) where the cue no longer resulted in the outcome.
- * The study found that changing the context during extinction training disrupted the participants' ability to stop responding to the cue, which has important implications for understanding how associative learning works.
Article Synopsis
- The attentional theory of context processing (ATCP) suggests that learning becomes linked to specific contexts when attention is focused on contextual stimuli, regardless of whether that focus is related to the learning itself or other activities.
- In an experiment, participants learned cue-outcome relationships while also completing a secondary task designed to influence their attention toward specific context elements.
- Results showed that changing the relevant context affected their predictive learning performance, validating ATCP principles, while changes in irrelevant contexts did not impact learning.
Article Synopsis
- This study investigates how people are more likely to learn fear responses toward members of an out-group as opposed to their own in-group when exposed to fear-inducing stimuli.
- Participants were shown faces from both groups, with some associated with a negative shock to measure their fear responses through physiological indicators.
- The findings indicate that while out-group faces did trigger increased fear responses, they don't show a stronger association with fear compared to in-group faces, suggesting a potential attentional bias where people focus more on in-group information.
It is widely held that the extinction of a conditioned response is more context specific than its initial acquisition. One proposed explanation is that context serves to disambiguate the meaning of a stimulus. Using a procedure that equated the learning histories of the contexts, we show that the memory of an appetitive Pavlovian association can be highly context specific despite being unambiguous.

The contexts were each composed of two elements from two dimensions, A and B. In Phase 1 of each experiment, participants received acquisition training with a target cue Z in context A1B1 (the numbers assign particular values on the context dimensions).

The phenomenon may provide insight into relapse that may occur after incentive or contingency management therapies in humans. Three experiments with rats examined the impact of several variables on the strength of the resurgence effect.

During Phase 1 of each experiment, participants received either a conditional discrimination in which contexts were relevant (Group Relevant) or a simple discrimination in which contexts were irrelevant (Group Irrelevant). Each experiment also included an ABA renewal procedure.
