I'm wondering, do you use chatgpt or other ai tools at all? Or do you use them in a "critical way"?

Cognitive computational model reveals repetition bias in a sequential decision-making task - Communications Psychology Using a sequential decision making task and cognitive modeling, we show that human decisions are best explained by a combination of repetition bias and goal directed reward-based behavior.

Participants enhanced or inhibited their habitual responses based on whether they were congruent or incongruent with goal-directed behavior.
Using drift-diffusion modeling, we found that habitual and goal-directed response tendencies interact on the level of evidence accumulation (drift-rate).

We discovered that the influence of a habit isn’t static, it depends on the number of repetitions of an action sequence.
🧠 Approximately 60% of participants adaptively adjusted their habitual responses according to the task context.

Context-Dependent Interaction Between Goal-Directed and Habitual Control Under Time Pressure Habits are an important aspect of human behaviour. Habits are reflexive, inflexible, and fast, in contrast to goal-directed behaviour which is reflective, flexible, and slow. Current theories assume t...

In our new preprint @saschafrolich.bsky.social , @MichaelSmolka & @StefanKiebel on how "habits interact with goal-directed behavior under time pressure", we found that habitual behavior varies as a function of context and repetition πŸ”„ www.biorxiv.org/content/10.1...

3/4 Findings suggest that chronic DBS can modulate this cognitive function over time. Results further hint at a role of the human NAcc region in maintaining our preferences over time as stimulation in this motivational hub can reshape preferences believed to rely on this circuit.

2/4 While short-term stability remains, long-term (6 months) reliability is disrupted. Temporal discounting (choosing between near and distant rewards) is relatively stable in humans and extreme patterns of discounting at least correlate with various mental disorders.

1/4 🧠 In our latest work jneurosci.org/content/43/4...
@peterslab.bsky.social we show that chronic deep brain stimulation (DBS) of the anterior limb of the internal capsule/NAcc region impacts the reliability of intertemporal preferences in patients with treatment-resistant OCD.
