Lupker, Stephen J.; Acha, Joana; Davis, Colin J.; Perea, Manuel – Journal of Experimental Psychology: Human Perception and Performance, 2012
In most current models of word recognition, the word recognition process is assumed to be driven by the activation of letter units (i.e., that letters are the perceptual units in reading). An alternative possibility is that the word recognition process is driven by the activation of grapheme units, that is, that graphemes, rather than letters, are…

Hayworth, Kenneth J.; Lescroart, Mark D.; Biederman, Irving – Journal of Experimental Psychology: Human Perception and Performance, 2011
Late ventral visual areas generally consist of cells having a significant degree of translation invariance. Such a "bag of features" representation is useful for the recognition of individual objects; however, it seems unable to explain our ability to parse a scene into multiple objects and to understand their spatial relationships. We…

Wendt, Mike; Luna-Rodriguez, Aquiles; Jacobsen, Thomas – Journal of Experimental Psychology: Human Perception and Performance, 2012
In a variety of conflict paradigms, target and distractor stimuli are defined in terms of perceptual features. Interference evoked by distractor stimuli tends to be reduced when the ratio of congruent to incongruent trials is decreased, suggesting conflict-induced perceptual filtering (i.e., adjusting the processing weights assigned to stimuli…

Cornell, Sonia A.; Lahiri, Aditi; Eulitz, Carsten – Journal of Experimental Psychology: Human Perception and Performance, 2013
The precise structure of speech sound representations is still a matter of debate. In the present neurobiological study, we compared predictions about differential sensitivity to speech contrasts between models that assume full specification of all phonological information in the mental lexicon with those assuming sparse representations (only…

Bukach, Cindy M.; Vickery, Timothy J.; Kinka, Daniel; Gauthier, Isabel – Journal of Experimental Psychology: Human Perception and Performance, 2012
There is growing evidence that individuation experience is necessary for development of expert object discrimination that transfers to new exemplars. Individuation training in human studies has primarily used label association tasks where labels are learned at both the individual and more abstract (basic) level, and expertise criterion requires…

Yamaguchi, Motonori; Logan, Gordon D.; Bissett, Patrick G. – Journal of Experimental Psychology: Human Perception and Performance, 2012
Although dual-task interference is ubiquitous in a variety of task domains, stop-signal studies suggest that response inhibition is not subject to such interference. Nevertheless, no study has directly examined stop-signal performance in a dual-task setting. In two experiments, stop-signal performance was examined in a psychological refractory…

Gondan, Matthias; Blurton, Steven P.; Hughes, Flavia; Greenlee, Mark W. – Journal of Experimental Psychology: Human Perception and Performance, 2011
When participants respond to auditory and visual stimuli, responses to audiovisual stimuli are substantially faster than to unimodal stimuli (redundant signals effect, RSE). In such tasks, the RSE is usually higher than probability summation predicts, suggestive of specific integration mechanisms underlying the RSE. We investigated the role of…

Bugg, Julie M.; Jacoby, Larry L.; Chanani, Swati – Journal of Experimental Psychology: Human Perception and Performance, 2011
The item-specific proportion congruency (ISPC) effect is the finding of attenuated interference for mostly incongruent as compared to mostly congruent items. A debate in the Stroop literature concerns the mechanisms underlying this effect. Noting a confound between proportion congruency and contingency, Schmidt and Besner (2008) suggested that…

Mitterer, Holger – Journal of Experimental Psychology: Human Perception and Performance, 2011
Four visual-world experiments, in which listeners heard spoken words and saw printed words, compared an optimal-perception account with the theory of phonological underspecification. This theory argues that default phonological features are not specified in the mental lexicon, leading to asymmetric lexical matching: Mismatching input…

Brooks, Daniel I.; Rasmussen, Ian P.; Hollingworth, Andrew – Journal of Experimental Psychology: Human Perception and Performance, 2010
In a contextual cuing paradigm, we examined how memory for the spatial structure of a natural scene guides visual search. Participants searched through arrays of objects that were embedded within depictions of real-world scenes. If a repeated search array was associated with a single scene during study, then array repetition produced significant…

Lindsen, Job P.; de Jong, Ritske – Journal of Experimental Psychology: Human Perception and Performance, 2010
Lien, Ruthruff, Remington, & Johnston (2005) reported residual switch cost differences between stimulus-response (S-R) pairs and proposed the partial-mapping preparation (PMP) hypothesis, which states that advance preparation will typically be limited to a subset of S-R pairs because of structural capacity limitations, to account for these…

Angele, Bernhard; Rayner, Keith – Journal of Experimental Psychology: Human Perception and Performance, 2011
We used the boundary paradigm (Rayner, 1975) to test two hypotheses that might explain why no conclusive evidence has been found for the existence of n + 2 preprocessing effects. In Experiment 1, we tested whether parafoveal processing of the second word to the right of fixation (n + 2) takes place only when the preceding word (n + 1) is very…
