Exogenous attention can be counter-selective: onset cues disrupt sensitivity to color changes

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Attention

Background:

• Exogenous attentional capture occurs with salient onset cues or cues predicting target features.
• Attentional capture is hypothesized to impair feature-based target selection.
• Everyday scenarios often involve monitoring for changes, making attentional capture relevant.

Purpose of the Study:

• To investigate how salient onset cues and contingent cues affect target detection sensitivity and response bias.
• To determine if exogenously captured attention disrupts feature selectivity.
• To explore the interaction between attentional capture, task difficulty, and attentional control.

Main Methods:

• Peripheral spatial cueing paradigms were employed.
• Experimentally simulated salient onset cues and contingent cues.
• Target detection sensitivity and response bias (in a go-nogo task) were measured.
• Task difficulty was manipulated to assess its interaction with cueing effects.

Main Results:

• Both onset and contingent cues reduced target detection sensitivity.
• Both cue types enhanced response bias in the go-nogo task.
• Onset cue effects on sensitivity were lateralized; contingent cue effects were bilateral.
• Onset cue effects interacted with task difficulty, with higher task demands increasing immunity but response likelihood.

Conclusions:

• Onset attentional capture disrupts selective attention by introducing noise into target location processing.
• Contingent capture effects can be attributed to cue-target confounding.
• A novel model is proposed where exogenous and endogenous attentional components interact dynamically.
