A Dual-Task Paradigm to Study the Interference Reduction in the Simon Task

Experimental Psychology, 2015
Analyzing RT distributions in the Simon task reveals that congruency effects decrease for the longest RTs. Four experiments were carried out to examine whether this decrease of the congruency effect with response speed was under a top-down control or due to bottom-up mechanisms.

Aging and the Simon task

Psychophysiology, 2002
A visual Simon task was used to study the influence of aging on visuospatial attention and inhibitory control processes. Responses were much slower for elderly than for young participants. The delay in trials in which stimulus and response side did not correspond as compared to when they did correspond (the Simon effect) was larger for older people ...

Influence of Time Pressure in a Simple Response Task, a Choice-by-Location Task, and the Simon Task

Journal of Psychophysiology, 2001
Abstract The influence of strategy was examined for a simple response task, a choice-by-location task, and the Simon task by varying time pressure. Besides reaction time (RT) and accuracy, we measured response force and derived two measures from the event-related EEG potential to form an index for attentional orienting (posterior contralateral ...

Response coding in the Simon task

Psychological Research, 2005
Recent findings indicate that two distinct mechanisms can contribute to a Simon effect: a visuomotor information transmission on the one hand and a cognitive code interference on the other hand (see for e.g., Wiegand & Wascher, in Journal of Experimental Psychology: Human Perception and Performance 2005a).

Assessing Anxiety with Extrinsic Simon Tasks

Experimental Psychology, 2006
This article introduces two new indirect measures of anxiety that are based on the Extrinsic Affective Simon Task (EAST; De Houwer, 2003 ). The EAST differs from the more established Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998 ) in that participants' responses to different trials within one block of trials are compared ...

The Extrinsic Affective Simon Task

Experimental Psychology, 2003
Abstract. A modified version of the Implicit Association Test (IAT) is described that is based on a comparison of performance on trials within a single task rather than on a comparison of performance on different tasks. In two experiments, participants saw white words that needed to be classified on the basis of stimulus valence and colored words that ...

Facilitation and interference components in the joint Simon task

Experimental Brain Research, 2011
Two experiments were conducted to assess whether the joint Simon effect is composed of facilitation and interference and whether facilitation is increased by a joint spatially compatible practice performed before performing the joint Simon task. In both experiments, participants were required to perform a Simon task along another person.

Priming processes in the Simon task: More evidence from the lexical decision task for a third route in the Simon effect.

Journal of Experimental Psychology: Human Perception and Performance, 2011
Recently, it was proposed that the Simon effect would result not only from two interfering processes, as classical dual-route models assume, but from three processes. It was argued that priming from the spatial code to the nonspatial code might facilitate the identification of the nonspatial stimulus feature in congruent Simon trials.
