    Influence on Simon and SNARC effects of a nonspatial stimulus-response mapping: between-task logical recoding.

    In 4 experiments, we intermixed trials in which the stimulus color was relevant with trials where participants had to judge the stimulus shape or parity and found that the logical-recoding rule (Hedge & Marsh, 1975) applied to the relevant dimension in a task can generalize to the irrelevant dimension of the other task. The mapping assigned to participants in color-relevant trials modulated the Simon and SNARC (spatial-numerical association of response codes) effects (Simon & Small, 1969; Dehaene, Bossini, & Giraux, 1993) observed in shape- and parity-relevant trials. Standard effects were obtained when color-relevant trials required participants to respond by pressing a key of the same color as the stimulus, whereas an alternate-color mapping caused either the disappearance or reversal of the effects. The present results demonstrate that for between-task transfer effects to occur the critical dimensions in the two alternative tasks do not have to share the same representation nor need the stimuli of the two tasks have any feature in common.

    Logical recoding of S-R rules can reverse the effects of spatial S-R correspondence.

    Two experiments investigated competing explanations for the reversal of spatial stimulus-response (S-R) correspondence effects (i.e., Simon effects) with an incompatible S-R mapping on the relevant, nonspatial dimension. Read More
    Automatic response activation of implicit spatial information: Evidence from the SNARC effect.

    In the present paper, we focus on how irrelevant implicit spatial information is processed. By irrelevant we mean information that is not required to fulfill the task and by implicit we mean information that is not directly available in the external stimulus. A good example of a task in which such information exists is the SNARC task [Dehaene, S. Read More
    Processing irrelevant location information: practice and transfer effects in choice-reaction tasks.

    Left or right keypresses to a relevant stimulus dimension are faster when the stimulus location, although irrelevant, corresponds with that of the response than when it does not. This phenomenon, called the Simon effect, persisted across 1,800 trials of practice, although its magnitude was reduced. Practice with the relevant stimulus dimension presented at a centered location had little influence on the magnitude of the Simon effect when irrelevant location was varied subsequently, and practice with location irrelevant prior to performing with location relevant slowed responses.

    Interference between nonspatial stimulus features in the Simon effect.
    Am J Psychol 2009 ;122(4):431-53
    University of Padua, Italy.
    We investigated whether learning effects influencing the Simon effect, such as those found when learning involves the spatial stimulus dimension, might be also found when learning tasks involve other nonspatial stimulus features, such as color, shape, and orientation. Experiment 1 focused on mutual influences between Simon tasks based on color and shape. The Simon task on color is affected by a previously performed Simon task on shape more than the latter is affected by a previously performed Simon task on color. Read More
