- The Simon effect refers to the fact that, even though stimulus position is task-irrelevant, responses to a task-relevant stimulus dimension are faster and more accurate when the stimulus and response spatially correspond than when they do not.

Oct 7, 2020 · This spatial interference, known as Simon effect, is obtained with visual (Craft & Simon, 1970), auditory (Simon & Small, 1969), and somatosensory (Hasbroucq & Guiard, 1992) stimulation, regardless of whether the participants respond by using hand, foot or eye movements (Leuthold & Schröter, 2006).
The Simon effect (Simon and Rudell, 1967) refers to the finding that spatially arranged responses to non-spatial stimulus features (such as shape, color etc.) are faster when the task-irrelevant stimulus location and response location correspond compared to when they do not correspond (Leuthold, 2011).
Aug 7, 2020 · Although the Simon effect is a very robust phenomenon, it is modulated by practice or transfer from previous tasks. Practice refers to the modulation of the Simon effect as a function of number of trials. Transfer refers to the modulation of the Simon effect as a function of preceding tasks.

The Simon effect is here reported as the average response time in incompatible trials minus the average response time in compatible trials. Typically, this is around 35 ms. Note, you can show your response times and copy and paste them to a local file for your own data analysis.
Mar 3, 2023 · The Simon effect asymmetry refers to the common finding that, with left and right index-finger press responses, the Simon effect is larger for one stimulus location than for the other.

Aug 7, 2020 · Although the Simon effect is a very robust phenomenon, it is modulated by practice or transfer from previous tasks. Practice refers to the modulation of the Simon effect as a function of number of trials. Transfer refers to the modulation of the Simon effect as a function of preceding tasks.
Oct 8, 2020 · In particular, the task generates two theoretically interesting effects: the Simon effect proper and the sequential modulations of this effect.
