Adaptation of the Mullen Scales of Early Learning for use among infants aged 5- to 24-months in rural Gambia.
(Wiley, 2019-02-09)Infants in low-resource settings are at heightened risk for compromised cognitive development due to a multitude of environmental insults in their surroundings. However, the onset of adverse outcomes and trajectory of ... -
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 ... -
An automated platform for high-throughput mouse behavior and physiology with voluntary head-fixation.
(2017-10-30)Recording neural activity during animal behavior is a cornerstone of modern brain research. However, integration of cutting-edge technologies for neural circuit analysis with complex behavioral measurements poses a severe ... -
Dopamine enhances model-free credit assignment through boosting of retrospective model-based inference.
(eLife, 2021-12-09)Dopamine is implicated in representing model-free (MF) reward prediction errors a as well as influencing model-based (MB) credit assignment and choice. Putative cooperative interactions between MB and MF systems include a ... -
Efficiency and prioritization of inference-based credit assignment.
(Elsevier, 2021-07-12)Organisms adapt to their environments by learning to approach states that predict rewards and avoid states associated with punishments. Knowledge about the affective value of states often relies on credit assignment (CA), ... -
Exploration heuristics decrease during youth.
(Springer Nature, 2022-10)Deciding between exploring new avenues and exploiting known choices is central to learning, and this exploration-exploitation trade-off changes during development. Exploration is not a unitary concept, and humans deploy ... -
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 ... -
Working memory recruits long-term memory when it is beneficial: Evidence from the Hebb effect.
(2022-04)When encoding task-relevant information in working memory (WM), we can use prior knowledge to facilitate task performance. For instance, when memorizing a phone number, we can benefit from recognizing some parts as known ...
