This study found no right-left prevalence effect in the Simon task when stimulus location was irrelevant. Manipulating dimension salience affected Simon effects but did not reveal an overall prevalence effect.

Area of Science:

  • Cognitive Psychology
  • Human Information Processing

Background:

  • The Simon task investigates stimulus-response compatibility.
  • A prevalence effect suggests one dimension (e.g., right-left) influences performance more than another (e.g., up-down).

Purpose of the Study:

  • To determine if a right-left prevalence effect exists in the Simon task.
  • To examine the influence of stimulus and response salience on the Simon effect across horizontal and vertical dimensions.

Main Methods:

  • Four experiments were conducted using the Simon task.
  • Stimulus and response sets varied simultaneously along horizontal and vertical dimensions.
  • Relative salience of dimensions was manipulated.

Main Results:

Related Experiment Videos

  • Simon effects were observed for both horizontal and vertical dimensions, with similar magnitudes.
  • Increased salience of a dimension led to a larger Simon effect for that dimension.
  • No overall prevalence effect was found.

    • Conclusions:

    • The right-left prevalence effect is not present when stimulus location is irrelevant in the Simon task.
    • Salience manipulations impact automatic response activation but not a general prevalence effect.
    • Intentional response selection, influenced by coding bias, may underlie the right-left prevalence effect when stimulus location is relevant.
