Overview

Behavioral study reveals that memory capacity, chronic stress, and depression predict cognitive effort allocation in humans, indicating that mental states critically shape decision-making.

Key Points

To establish how cognitive capacity, chronic stress, depression, and personal preferences predict choices regarding cognitive effort allocation under static and shifting reward and demand conditions.
Administered visual short-term memory choice tasks with translationally relevant paradigms based on rodent effort research.
Assessed individual differences in visual short-term memory capacity, chronic stress, depression levels, and attentional preferences across static and shifting effort-reward scenarios.
Higher visual short-term memory capacity consistently predicted an increased preference for high-effort, high-reward options.
Under shifting demands and rewards, lower chronic stress and greater preferences for attentional control, combined with higher visual short-term memory, predicted choices to encode larger stimulus sets for higher rewards.
Elevated depression levels were specifically associated with impairments in choosing high-effort options in the presence of potential loss outcomes.
