This study introduces a new theory of decision-making, showing how reward desirability and cognitive effort control decision processes. It explains behaviors like "choking under pressure" and unifies neural and behavioral findings.
Area of Science:
- Neuroscience
- Cognitive Science
- Decision Theory
Background:
- Existing decision-making theories lack a unifying principle for neural tuning.
- Behavior is heavily influenced by reward desirability and effort costs.
Purpose of the Study:
- To develop a unifying theory of perceptual decision-making.
- To explain how desirability and effort influence deliberation control gains.
Main Methods:
- Developed a computational model integrating desirability and cognitive effort.
- Analyzed emergent behavioral and neural dynamics from the model.
Main Results:
- Model reproduces hallmark decision behaviors, resembling low-dimensional neural dynamics.
- Provides a mechanistic explanation for "choking under pressure" due to extreme rewards.
- Framework unifies disparate behavioral and neural phenomena.
Conclusions:
- Desirability and cognitive effort are key principles tuning decision control.
- The model offers a principled framework for understanding decision-making and its neural underpinnings.

Decision Making: P-value Method
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can have a...
