Article Abstract
We demonstrated that alcohol-dependent patients who relapsed within 1 year after detoxification showed stronger PIT effects compared with abstainers and controls. Relapsers particularly failed to correctly perform in trials where an instrumental stimulus required inhibition while a Pavlovian background cue indicated a monetary gain. Under that condition, relapsers approached the instrumental stimulus, independent of the expected punishment. The failure of inhibiting an aversive stimulus in favor of approaching an appetitive context cue reflects dysfunctional altered learning mechanisms in relapsers.

Risky online buying-shopping behavior: The role of stress responsivity on the transfer from goal-directed behavior to stimulus-response habits.
J Behav Addict
September 2025
1Department of Psychosomatic Medicine and Psychotherapy, Hannover Medical School, Hanover, Germany.
Background And Aim: There is a lack of research on the stress-related transfer from goal-directed behavior to stimulus-response habits in (early stages of) online buying-shopping disorder (BSD). This study investigated the Pavlovian-to-instrumental transfer (PIT) effect after reward devaluation (PIT-dev) as indicator of habitual behavior and its modulation by acute stress in individuals with risky (online) buying-shopping (r-BSh).
Methods: Individuals with r-BSh (n = 67) and a control group (n = 67) underwent a PIT paradigm with devaluation procedure.
Unilateral Stimulation of the Dorsolateral Striatum Attenuates Goal-Directed Action.

It has long been known that the dorsomedial (DMS) and dorsolateral striatum (DLS) mediate distinct forms of action control, with DMS mediating goal-directed actions and DLS mediating habits. Recent evidence suggests that, in accord with its role in goal-directed control, unilateral stimulation of dorsomedial striatum (DMS) enhances actions contralateral to the stimulation in a manner that scales with the prior reward history of that action. In the current study, we assessed whether the effects of unilateral stimulation of the dorsolateral striatum (DLS) induce a response bias that reflects enhanced habitual control, as measured by the effect of stimulation on ongoing goal-directed control.

Behavioural inflexibility-a hallmark of autism spectrum disorder (ASD)-can be characterised by the persistence of established behaviours in inappropriate contexts. This inflexibility may arise from a reduced ability to use contextual information to disambiguate effective contingencies, thereby impeding the flexible expression of instrumental behaviour in a contextually appropriate manner. In this study, we employed the BTBR T tf inbred mouse model of ASD to examine whether contextual control of behaviour is impaired in these mice.

Habitual control of repeated behaviours is adaptive because it can allow routine behaviours to continue under conditions where cognitive capacity is limited or burdened. However, the impact that cognitive demand has on behavioural control has not been thoroughly studied in animal models of habits. This study used a strain of rats-spontaneously hypertensive rats (SHRs)-that have known cognitive deficits to investigate their ability to update their behaviour following changes to outcome value, instrumental contingency, and the predictions of stimuli across multiple tasks.

Interoception and associated subjective states shape adaptive behaviors. In humans, interoceptive information is hierarchically processed in the insular cortex (IC), being integrated first in the posterior IC (PIC) and then processed in the anterior IC (AIC) to generate subjective states. However, it has not been established whether this is the case in other species nor whether utilization of interoceptive states to guide behavior is also specifically associated with functional engagement of the AIC, as suggested by this hierarchical model.
