Atypical action updating in a dynamic environment associated with adolescent obsessive-compulsive disorder.
(Wiley, 2022-05-10)BACKGROUND: Computational research had determined that adults with obsessive-compulsive disorder (OCD) display heightened action updating in response to noise in the environment and neglect metacognitive information (such ... -
Distributed context-dependent choice information in mouse posterior cortex.
(2023-01-12)Choice information appears in multi-area brain networks mixed with sensory, motor, and cognitive variables. In the posterior cortex-traditionally implicated in decision computations-the presence, strength, and area specificity ... -
Evidence integration and decision confidence are modulated by stimulus consistency.
(Nature Research, 2022-07)Evidence integration is a normative algorithm for choosing between alternatives with noisy evidence, which has been successful in accounting for vast amounts of behavioural and neural data. However, this mechanism has been ... -
The hippocampus and orbitofrontal cortex jointly represent task structure during memory-guided decision making
(Cell Press, 2021-11-30)The hippocampus, well known for its role in episodic memory, might also be an important brain region for extracting structure from our experiences in order to guide future decisions. Recent evidence in rodents suggests ... -
Human subjects exploit a cognitive map for credit assignment.
(PNAS, 2021-01-26)An influential reinforcement learning framework proposes that behavior is jointly governed by model-free (MF) and model-based (MB) controllers. The former learns the values of actions directly from past encounters, and the ... -
Model based planners reflect on their model-free propensities.
(PLOS, 2021-01)Dual-reinforcement learning theory proposes behaviour is under the tutelage of a retrospective, value-caching, model-free (MF) system and a prospective-planning, model-based (MB), system. This architecture raises a question ... -
Neurocomputational mechanisms of confidence in self and others.
(Nature Research, 2022-07-22)Computing confidence in one's own and others' decisions is critical for social success. While there has been substantial progress in our understanding of confidence estimates about oneself, little is known about how people ...
