The Simon effect arises from visuomotor transmission or cognitive code interference, depending on response coding. Visuomotor transmission occurs when stimulus location overlaps with motor response representations.

Area of Science:

  • Cognitive Psychology
  • Human Perception and Performance
  • Motor Control

Background:

  • The Simon effect can be explained by two mechanisms: visuomotor information transmission and cognitive code interference.
  • The dominant mechanism is hypothesized to depend on how responses are coded.
  • Visuomotor transmission relates to stimulus-effector correspondence, while cognitive interference relates to response location codes.

Purpose of the Study:

  • To investigate the spatial anatomic coding hypothesis of the Simon effect.
  • To examine the role of visuomotor information transmission in unimanual responses across different stimulus-response (S-R) spatial configurations.
  • To determine if the motor representation is task-dependent.

Main Methods:

  • Three experiments were conducted using unimanual responses.

  • The Simon effect was investigated for both horizontal and vertical S-R relations.
  • Effect functions were analyzed to identify the presence of visuomotor information transmission.

    • Main Results:

    • A decreasing effect function, indicative of visuomotor information transmission, was observed for both horizontal and vertical S-R relations.
    • This suggests visuomotor information transmission is not limited to specific S-R orientations.
    • The findings support the idea that visuomotor transmission occurs with spatial overlap between stimulus and response.

    Conclusions:

    • Visuomotor information transmission in the Simon effect occurs when spatial stimulus features overlap with the motor representation of the response.
    • The specific motor representation utilized is task-dependent, reflecting parameters that distinguish response alternatives.
    • This provides evidence for a spatially based visuomotor mechanism influencing performance in tasks with spatial S-R compatibility.
