Summary

This summary is machine-generated.

Increased motivation improves task accuracy by enhancing effort, not eye movement strategy. Participants showed better discrimination performance with rewards, suggesting motivation drives attention and reduces errors.

Area of Science:

Cognitive psychology
Neuroscience
Decision-making

Background:

Fixation decisions are often inefficient and variable.
Understanding factors influencing decision-making efficiency is crucial.

Purpose of the Study:

To investigate if increased motivation improves fixation decisions and task performance.
To compare performance with and without motivation-based rewards.

Main Methods:

A visual discrimination task where participants chose fixation locations before target appearance.
Gamified task with accuracy-contingent rewards to motivate participants.
Bayesian beta regression analysis to evaluate performance differences.

Main Results:

Discrimination accuracy significantly improved with performance-related rewards.
No significant difference in eye movement strategy was observed between motivated and unmotivated groups.
Improvement in accuracy was attributed to increased effort, attention, and reduced response errors.

Conclusions:

Motivation enhances task performance primarily through increased effort and attention, rather than optimizing eye movement strategies.
Gamification can be an effective tool to boost performance in cognitive tasks.
Future research should explore other motivational factors and their impact on decision-making.
