The location independence of learned attentional flexibility

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Attention

Background:

• Attentional flexibility allows individuals to adapt their attention based on environmental statistics.
• It remains unclear if this adaptation involves a general readiness to shift attention or a specific anticipation of a location.

Purpose of the Study:

• To investigate whether modulations in attentional flexibility reflect a global readiness to shift attention or a location-specific anticipation.
• To differentiate between location-independent and location-dependent attentional control.

Main Methods:

• Two experiments involving participants shifting attention between rapid serial visual presentation (RSVP) streams.
• Manipulation of the likelihood of cued attention shifts between specific locations.
• Measurement of target detection shift costs and saccade latencies.

Main Results:

• Participants showed reduced shift costs and faster saccade latencies when the overall likelihood of shifting attention was high.
• Evidence for both global shift readiness and location-specific readiness was observed.
• Attention shifts to the most probable location were fastest, but shifts to less likely locations were still influenced by overall shift likelihood.

Conclusions:

• Moment-to-moment changes in attentional flexibility are not solely based on anticipating a single location.
• Attentional flexibility involves a partially location-independent state of control, reflecting a global readiness to shift attention.
