- 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 · For as long as half a century the Simon task – in which participants respond to a nonspatial stimulus feature while ignoring its position – has represented a very popular tool to study a variety of cognitive functions, such as attention, cognitive control, and response preparation processes.
The Simon Effect refers to the phenomenon where participants in experiments show faster reaction times when pressing a button on the side corresponding to the location of a stimulus, even when the location is irrelevant to the task. This effect demonstrates that even incidental features of stimuli can influence response compatibility.
In essence, it shows that people respond faster and more accurately if there is a match between stimulus and response features (e.g., location, when for example stimulus and response are both located on the left side of one’s body). The effect is also known as a stimulus-response compatibility effect.
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.

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.
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), tran...
