Sensory sensitivity: Should we consider attention in addition to prediction?

Area of Science:

• Cognitive Neuroscience
• Psychology
• Sensory Perception

Background:

• Perception is shaped by sensory input, predictions, and prior knowledge.
• Individual differences in sensory sensitivity are not fully explained by existing models.

Purpose of the Study:

• To propose a framework for understanding sensory sensitivity.
• To integrate selective attention into models of perception and sensory sensitivity.

Main Methods:

• Review of signal detection theory and predictive coding.
• Theoretical argument for the inclusion of behavioral relevance.

Main Results:

• Sensory sensitivity is determined by sensory input, prior knowledge, and behavioral relevance.
• Selective attention is a key mechanism influencing perception.

Conclusions:

• A comprehensive understanding of sensory sensitivity requires considering selective attention.
• Future research should incorporate behavioral relevance in the study of sensory perception.
