The locus coeruleus-norepinephrine (LC-NE) system underlies the attentional blink, a deficit in identifying targets. Increased target-distractor interference temporarily enhances the LC-NE system response.

Area of Science:

  • Neuroscience
  • Cognitive Psychology

Background:

  • The attentional blink is a phenomenon where accuracy decreases for the second target in rapid serial visual presentation.
  • Existing models suggest the locus coeruleus-norepinephrine (LC-NE) system's autoinhibitory nature causes this deficit.

Purpose of the Study:

  • To investigate the role of the LC-NE system as the neurophysiological basis of the attentional blink.
  • To propose and test a modified LC-NE account of the attentional blink.

Main Methods:

  • Manipulating target-distractor interference by reducing the time interval between them.
  • Assessing accuracy in reporting the second target under varying interference conditions.

Main Results:

  • A benefit in identifying the second target was observed up to 200 msec after the first target's onset in high-interference conditions.

Measurement of Neurophysiological Signals of Ignoring and Attending Processes in Attention Control

  • Accuracy decreased thereafter, consistent with the attentional blink phenomenon.
  • Results suggest a temporarily enhanced LC-NE system response to increased target-distractor interference.

    • Conclusions:

    • The LC-NE system is the neurophysiological basis of the attentional blink.
    • Increased target-distractor interference elicits a temporarily enhanced LC-NE system response, modifying the attentional blink effect.
