Object-based attention is accentuated by object reward association.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Perception

Background:

• Selective attention prioritizes visual features and locations based on reward.
• Object-based attention selects entire objects, not just specific parts.
• The interaction between reward and object-based attention is not well understood.

Purpose of the Study:

• To investigate how reward prioritization interacts with object prioritization in visual cognition.
• To determine if reward associations influence object-based attention.
• To examine the persistence and interaction of these attentional effects.

Main Methods:

• Four experiments were conducted to test the interaction between reward and object prioritization.
• Experiment 1: Assessed if reward feedback negates object prioritization.
• Experiments 2-4: Examined the concurrent emergence, extinction, and persistence of reward and object prioritization interactions.

Main Results:

• Reward feedback does not override object prioritization.
• Reward and object prioritization emerge and interact concurrently.
• These interactions persist even when reward feedback is discontinued (extinction).
• The interaction is linked to task experience, not just strategic reward utility.

Conclusions:

• Reward prioritization and object prioritization interact dynamically in visual attention.
• Reward-associated objects gain preferential cognitive access.
• Understanding this interaction provides insights into how the brain guides selection based on learned value and object structure.
