Stochastic Decision Policy Is Optimal Under Costly Control

This paper shows that stochastic decision policies can be optimal when considering the cost of control, using sequential sampling and recovering policies in macaques.

Neural representation of the decisional reference point in monkeys

This study identifies neural encoding of the decisional reference point in macaques, showing that only the ventral bank of the anterior cingulate cortex encodes it at the population level.

Early versus late noise differentially enhances or degrades context-dependent choice

The paper investigates how early versus late noise affects context-dependent choice behavior in decision-making, showing opposing effects on choice accuracy.

Decisional reference point pathology: a mechanism and marker for major depressive disorder in humans

This paper identifies a pathological elevation of the decisional reference point in depression patients, linking it to disease severity and proposing a virtual diagnostic test.

A Tale of Two Environments: Divisive Normalization and the (In)Flexibility of Choice

This study shows humans use divisive normalization in two different choice environments, suggesting it is a fixed cognitive mechanism.

Flexible control of representational dynamics in a disinhibition-based model of decision making

This paper introduces a hybrid neural circuit model that combines normalized representation and winner-take-all dynamics through disinhibition, capturing decision-making behaviors and working memory.

Context-dependent choice and evaluation in real-world consumer behavior

The paper examines context-dependent choice in real-world settings using restaurant rating data, finding that valuations and choices are influenced by the context of available options.

Asymmetric and adaptive reward coding via normalized reinforcement learning

This study shows that nonlinear reinforcement learning with divisive normalization introduces asymmetry in prediction error coding, explaining behavioral variability and supporting distributional RL theories.

Input-Specific Inhibitory Plasticity Improves Decision Accuracy Under Noise

The paper investigates inhibitory plasticity in mouse auditory cortex, finding that SST+ interneuron inputs show the most potentiation and contribute to decision accuracy under noise.

Hierarchical Network Model Excitatory-Inhibitory Tone Shapes Alternative Strategies for Different Degrees of Uncertainty in Multi-Attribute Decisions

The paper models decision-making in a hierarchical neural network, showing how excitatory-inhibitory balance affects decision strategies under different uncertainty levels.

Bounded Rationality in C. elegans

This study tests the Independence of Irrelevant Alternatives in C. elegans using olfactory chemotaxis assays, showing that neuronal constraints can lead to bounded rationality.
