Difference in accuracy or reaction time
researchgate.net
- The Simon effect is the difference in accuracy or reaction time between trials in which stimulus and response are on the same side and trials in which they are on opposite sides, with responses being generally slower and less accurate when the stimulus and response are on opposite sides.

Oct 7, 2020 · In the present study, we review the main theoretical explanations of both kinds of effects and the available neuroscientific studies that investigated the neural underpinnings of the cognitive processes underlying the Simon effect proper and its sequential modulation using electroencephalogram (EEG) and event-related brain potentials (ERP ...
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).
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.
The Simon effect is the difference in accuracy or reaction time between trials in which stimulus and response are on the same side and trials in which they are on opposite sides, with responses being generally slower and less accurate when the stimulus and response are on opposite sides.
Feb 1, 2011 · This article discusses the major characteristics of the Simon effect and the Simon task that laid the ground for this success and reviews the major lines of research, theoretical developments, and ongoing controversies on and around the Simon Effect and the cognitive processes it reflects.

Oct 8, 2020 · In particular, the task generates two theoretically interesting effects: the Simon effect proper and the sequential modulations of this effect.
Feb 1, 2011 · A little more than 40 years ago, J. R. Simon and colleagues introduced what is now called the Simon task, which yielded a correspondence effect known as the Simon effect. In this paper, I set Simon's contribution in the context of research on stimulus-response compatibility.
