Stinchcombe, Eric J.; Lupker, Stephen J.; Davis, Colin J. – Language and Cognitive Processes, 2012
Three experiments are reported investigating the role of letter order in orthographic subset priming (e.g., "grdn"-GARDEN) using both the conventional masked priming technique as well as the sandwich priming technique in a lexical decision task. In all three experiments, subset primes produced priming with the effect being considerably…

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…

Van der Haegen, Lise; Brysbaert, Marc; Davis, Colin J. – Brain and Language, 2009
It has recently been shown that interhemispheric communication is needed for the processing of foveally presented words. In this study, we examine whether the integration of information happens at an early stage, before word recognition proper starts, or whether the integration is part of the recognition process itself. Two lexical decision…

Lupker, Stephen J.; Davis, Colin J. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2009
An orthographically similar masked nonword prime facilitates responding in a lexical decision task (Forster & Davis, 1984). Recently, this masked priming paradigm has been used to evaluate models of orthographic coding--models that attempt to quantify prime-target similarity. One general finding is that priming effects often do not occur when…

Davis, Colin J.; Perea, Manuel; Acha, Joana – Journal of Experimental Psychology: Human Perception and Performance, 2009
The influence of addition and deletion neighbors on visual word identification was investigated in four experiments. Experiments 1 and 2 used Spanish stimuli. In Experiment 1, lexical decision latencies were slower and less accurate for words and nonwords with higher-frequency deletion neighbors (e.g., "jugar" in "juzgar"),…

Davis, Colin J.; Bowers, Jeffrey S. – Journal of Experimental Psychology: Human Perception and Performance, 2006
Five theories of how letter position is coded are contrasted: position-specific slot-coding, Wickelcoding, open-bigram coding (discrete and continuous), and spatial coding. These theories make different predictions regarding the relative similarity of three different types of pairs of letter strings: substitution neighbors,…

Bowers, Jeffrey S.; Davis, Colin J.; Hanley, Derek A. – Cognition, 2005
We assessed the impact of visual similarity on written word identification by having participants learn new words (e.g. BANARA) that were neighbours of familiar words that previously had no neighbours (e.g. BANANA). Repeated exposure to these new words made it more difficult to semantically categorize the familiar words. There was some evidence of…
