Dissociable Components of Experience-Driven Attention.

Area of Science:

• Cognitive Neuroscience
• Psychology

Background:

• Attention is guided by task goals, stimulus salience, and selection history.
• Selection history, encompassing learning and conditioning, is often viewed as a unified attentional control mechanism.
• Previous models suggest a single process underlies selection history's influence on attention.

Purpose of the Study:

• To investigate whether distinct learning processes underlie selection history's influence on attention.
• To examine the dissociable consequences of these learning processes on orienting behavior.
• To challenge the notion of selection history as a unitary mechanism.

Main Methods:

• Human observers performed an antisaccade task with reward contingencies.
• Participants were trained to shift gaze opposite to color-defined targets for payment.
• Behavioral biases in orienting responses were measured.

Main Results:

• Associative learning created a bias to orient toward reward cues, even when counter to task goals.
• Instrumental conditioning led to repetitive orienting behavior, overriding current motivations.
• These findings indicate separate learning pathways shape attentional selection history.

Conclusions:

• Selection history is not a unitary mechanism but involves at least two distinct learning processes.
• Value-based attention demonstrates an approach orientation, impacting attentional bias modification techniques.
• Learning history dynamically shapes orienting behavior through multiple, separable routes.
