A computational model of the Simon effect
Psychological Research, 1995Even though stimulus location is task irrelevant, reaction times are faster when the location of the stimulus corresponds with the location of the response than when it does not. This phenomenon is called the Simon effect. Most accounts of the Simon effect are based on the assumption that it arises from a conflict between the spatial code of the ...

A Response-Discrimination Account of the Simon Effect.
Journal of Experimental Psychology: Human Perception and Performance, 2004Simon effects might partly reflect stimulus-triggered response activation. According to the response-discrimination hypothesis, however, stimulus-triggered response activation shows up in Simon effects only when stimulus locations match the top-down selected spatial codes used to discriminate between alternative responses. Five experiments support this

A simon effect with stationary moving stimuli.
Journal of Experimental Psychology: Human Perception and Performance, 2004To clarify whether motion information per se has a separable influence on action control, the authors investigated whether irrelevant direction of motion of stimuli whose overall position was constant over time would affect manual left-right responses (i.e., reveal a motion-based Simon effect).

The role of attention for the Simon effect
Psychological Research, 1993It has been claimed that spatial attention plays a decisive role in the effect of irrelevant spatial stimulus-response correspondence (i.e., the Simon effect), especially the way the attentional focus is moved onto the stimulus (lateral shifting rather than zooming).

The Simon effect has most often been investigated with key-press responses and eye fixation. In the present study, we asked how the type of eye movement and the type of manual response affect response selection in a Simon task. We investigated three eye movement instructions (spontaneous, saccade, and fixation) while participants performed goal ...

The Simon effect and visual motion
Psychological Research, 1994S-R compatibility and Simon effects were studied for real visual motion. In Experiment 1, two small stimulus lights were constantly visible, 5 degrees to the left and right of fixation; after a random delay, one began to move at 2 degrees/s. In Experiment 2, a single stimulus light moving at 2 degrees/s suddenly appeared 5 degrees to the left or right ...

Attention precuing and Simon effects: A test of the attention-coding account of the Simon effect
Psychological Research, 1995Simon effects refer to the finding that choice-response latencies to a nonspatial aspect of a stimulus vary depending on the spatial correspondence between the stimulus position and the position of the correct response alternative. Recently, researchers have proposed an attention-coding account of Simon effects whereby the (irrelevant) stimulus spatial

A Simon effect for stimulus-response duration
The Quarterly Journal of Experimental Psychology Section A, 2002A non-spatial variant of the Simon effect for the stimulus-response (S-R) feature of duration is reported. In Experiment 1 subjects were required to press a single response key either briefly or longer in response to the colour of a visual stimulus that varied in its presentation duration.

The Simon Effect With Saccadic Eye Movements
Experimental Psychology, 2016Abstract. In the Simon effect performance is faster and more accurate when the task-irrelevant spatial dimension of the stimulus corresponds to the location of the response, compared to when they do not correspond. In the prosaccade-antisaccade effect the latencies of saccades away from the stimulus location (i.e., antisaccades) are slower than the ...

Three experiments are reported in which a semantic variant of the Simon paradigm was used. In Experiment 1, participants saw Dutch and English words that corresponded to names of animals (e.g. DOG) or occupations (e.g. TEACHER). Participants were instructed to respond by saying ANIMAL or OCCUPATION, depending on whether the presented word was a Dutch ...
