Feedback Inhibition

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Summary

Salient stimuli can capture attention but are suppressible to prevent distraction. Research using the distractor positivity (PD) component, an ERP measure, supports this, offering insights into cognitive control and ignoring distractors.

Area of Science:

  • Cognitive Psychology
  • Neuroscience

Background:

  • The automatic distraction by salient stimuli remains debated.
  • Attentional suppression may prevent distraction from salient stimuli.

Purpose of the Study:

  • To review research on the distractor positivity (PD) ERP component.
  • To explore how PD elucidates inhibitory attentional processes and distraction management.

Main Methods:

  • Review of existing research utilizing the distractor positivity (PD) component.
  • Analysis of studies examining search strategy and learning effects on distraction.

Main Results:

  • The PD component is linked to inhibitory processes preventing distraction.
  • PD research provides insights into how cognitive strategies modulate distraction.

Conclusions:

  • The distractor positivity (PD) component is a valuable tool for studying inhibitory control.
  • PD may offer insights into broader cognitive control mechanisms.
