Older Adults Forage Broadly for Information Despite Cost

This study shows older adults prioritize information seeking over reward in a complex task, leading to slower learning but no long-term performance deficits.

Overcoming distortion in multidimensional predictive representation

The paper investigates how multidimensional predictive learning is distorted by spurious observations and shows how semantic inductive biases can mitigate these effects in human behavior.

Value construction through sequential sampling explains serial dependencies in decision making

The paper shows that subjective values change during decision-making tasks and introduces a model to detect these changes in choices and neural signals.

Neural Representations of Food-Related Attributes in the Human Orbitofrontal Cortex During Choice Deliberation in Anorexia Nervosa

The paper decodes neural representations of taste and health attributes in the OFC during food choices in AN patients and healthy individuals, finding stronger health-related associations in AN.

Memory for Individual Items is Related to Non-Reinforced Preference Change

The paper shows that memory for trained items enhances preference for high-value stimuli after non-reinforced cue-approach training, even months later.

Value-based decisions involve sequential sampling from memory

The paper shows that decision-making between similar options involves memory-based evidence construction, with hippocampal activity linked to deliberation time and value formation.
