Perceptual interactions between bilaterally presented words: What you get is often not what you see.

Abstract

Bilateral presentations of words, 1 in the left visual hemifield (LVF) and 1 in the right (RVF), are used widely in studies of hemispheric asymmetry. However, although words shown centrally (i.e., nonlaterally) produce perceptual interactions in which 1 word alters the perceived identity of the other, perceptual interactions between bilaterally presented words have never been reported. To investigate this issue, the authors used brief, bilateral displays of words (e.g., romp-ramp) presented simultaneously. An eye tracker and forced-choice task ensured appropriate presentation and testing. Report accuracy was greatest for RVF words. However, this was accompanied by perceptual interactions that occurred almost exclusively in responses to LVF words, indicating that RVF words often altered the perceived identity of LVF words but not vice versa.

Orthographic neighborhood effects during lateralized lexical decision are abolished with bilateral presentation.

“…In a more directly relevant VHF paradigm, Jordan and Patching (2003) examined the effect that bilateral presentation had on perceived word identity. On every trial, orthographic neighbors were briefly presented to each VHF (e.g., romp – ramp).…”

Assessing the importance of letter pairs in reading-parafoveal processing is not the only view: Reply to Inhoff, Radach, Eiter, and Skelly (2003).

“…1Although outside the focus of the present article, it should be noted that recent work with lateralized displays indicates that under conditions that suppress influences of guesswork, perceptual advantages for exterior letter pairs over letters in all other positions are present for isolated words presented up to 4° from the point of fixation (Jordan & Patching, in press; Jordan, Patching, & Milner, 2000; Jordan, Patching, & Thomas, 2003a, 2003b). …”
