Author summary Computational psychiatry is a field that makes extensive use of computational methods to understand mental health. In this field and related disciplines, there is a strong need to desig...

This study investigates the dynamic interplay between habitual and goal-directed control. Using RL and drift-diffusion modelling, we show that these systems interact in a context-dependent manner: hab...

Intertemporal choice involves decisions between rewards available at an earlier point in time and delayed rewards (delay discounting). Such decisions are common in everyday life, influencing outcomes ...

Implements an n-dimensional parameter space partitioning algorithm for evaluating the global behaviour of formal computational models as described by Pitt, Kim, Navarro and Myung (2006) &lt;<a href="h...

Control of behavior is often explained in terms of a dichotomy, with distinct neural circuits underlying goal-directed and habitual control, yet accumulating evidence suggests these processes are deep...

Translational Psychiatry - Model-based planning is unaffected by ketamine, antidepressant and internet delivered cognitive behavioural therapy treatments in depression

This study shows that decision biases previously attributed to value normalization (e.g. relative value learning or range normalization) are better explained by action repetition. Repeating an action ...

Nature Human Behaviour - In this study, Collins proposes an alternative dual-process (working memory and habit) model of reinforcement learning in humans.

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.

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.

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...

When choosing between rewards that differ in temporal proximity (intertemporal choice), human preferences are typically stable, constituting a clinically relevant transdiagnostic trait. Here we show, ...
