When up-down stimulus locations are mapped to left-right keypresses, an overall advantage for the up-right/down-left mapping is often obtained that varies as a function of response eccentricity. This orthogonal stimulus-response compatibility (SRC) effect also occurs when stimulus location is irrelevant, a phenomenon called the orthogonal Simon effect, and has been attributed to correspondence of stimulus and response code polarities. The Simon effect for horizontal stimulus-response (S-R) arrangements has been shown to be affected by short-term S-R associations established through the mapping used for a prior SRC task in which stimulus location was relevant.

The above-right/below-left mapping advantage with vertical stimuli and horizontal responses is known as the orthogonal stimulus-response compatibility (SRC) effect. We investigated whether the orthogonal SRC effect emerges with irrelevant stimulus dimensions. In Experiment 1, participants responded with a right or left key press to the colour of the stimulus presented above or below the fixation. Read More

When lateralized responses are made to the locations of vertically arrayed stimuli, two types of mapping effect have been reported: an overall up-right/down-left advantage and mapping preferences that vary with response position. According to Cho and Proctor's (2003) multiple asymmetric codes account, these orthogonal stimulus-response compatibility effects are due to the correspondence of stimulus polarity and response polarity, as determined by the positions relative to multiple frames of reference. The present study examined these two types of orthogonal compatibility for situations in which participants made left-right responses to the colours of a vertically arrayed stimulus set, and stimulus location was irrelevant.

In two experiments, we tested whether the emergence of the go/no-go Simon effect could be determined by the strengthening of one specific S-R link in location-relevant trials performed right before (practice paradigm) or simultaneously (mixing paradigm) with the location-irrelevant (Simon) trials. Results showed a clear carry-over effect of the association between stimulus position and spatial response from the first task to the second one (Experiment 1) and when the two tasks were performed simultaneously (Experiment 2), even if participants were required to respond with the same key to only half of the stimuli (go/no-go tasks). We found that associative learning between the stimulus and response positions occurring during the go/no-go compatibility task, that is when location was relevant, influenced the way the go/no-go location-irrelevant task (Simon task) was performed.
