Role of Pavlovian mechanisms for control over substance use (TRR 265 - Project B03))
Project Summary
Individuals with substance use disorders (SUD) have to cope with drug-related cues and contexts, which can affect instrumental drug seeking as shown with Pavlovian to instrumental transfer (PIT) paradigms in animals and humans. During the first funding period, we investigated the impact of acute and chronic stress on PIT and how PIT it is associated with cognitive control abilities. Moreover, we developed a novel full transfer task that allows assessing both, general and specific PIT to investigate whether specific PIT differs between alcohol use disorder (AUD) and control subjects.
In the second funding period, our project aims to accomplish several objectives related to PIT in individuals with SUD. Work package 1(WP1) will investigate how much of our understanding of PIT mechanisms can be generalized to other drugs of abuse, especially to cannabis and stimulants (e.g. methamphetamine) and how this can be compared to alcohol. WP2 will investigate how experimentally induced social exclusion impacts alcohol-specific and general PIT effects in participants with AUD and control participants. WP3 will examine whether PIT reflects more a controlled goal-directed process, or a more automatic, habitual process. WP4 will develop a PIT task that is suitable for repeated assessment to study how Pavlovian mechanisms influence the acquisition of instrumental behavior. Lastly, WP5 intends to create a gamified task that can be used for repeated PIT assessments via smartphone.
