Preparing to attend in a two-target task

Area of Science:

• Cognitive Psychology
• Neuroscience
• Experimental Psychology

Background:

• Selective attention is crucial for processing information.
• The attentional blink is a well-documented deficit in identifying a second target when it appears shortly after a first target.
• Understanding factors that modulate selective attention is key to cognitive function.

Purpose of the Study:

• To investigate the role of preparatory states in selective attention within a two-target task.
• To examine how preceding events influence attention to the first target (T1) and the attentional blink for the second target (T2).

Main Methods:

• Utilized a skeletal two-target paradigm.
• Introduced a preceding stimulus/response event before each two-target trial.
• Manipulated task instructions for the preceding event to assess their impact on attention.

Main Results:

• Neither T1 nor T2 identification was affected by the stimulus/response features of the preceding event.
• Both T1 and T2 identification were significantly influenced by the task instructions associated with the preceding event.
• The attentional blink for T2 was modulated by preparatory states.

Conclusions:

• Preparatory states, particularly those cued by task instructions, play a critical role in modulating selective attention.
• Cognitive control over attention is strongly influenced by anticipatory processes.
• Findings highlight the importance of task-set preparation in overcoming attentional limitations.
