Dickinson, Joël; Cirelli, Laura; Szeligo, Frank – Journal of Psycholinguistic Research, 2014
Dickinson and Szeligo ("Can J Exp Psychol" 62(4):211--222, 2008) found that processing time for simple visual stimuli was affected by the visual action participants had been instructed to perform on these stimuli (e.g., see, distinguish). It was concluded that these effects reflected the differences in the durations of these various…

Hannagan, Thomas; Grainger, Jonathan – Cognitive Science, 2012
It has been recently argued that some machine learning techniques known as Kernel methods could be relevant for capturing cognitive and neural mechanisms (Jakel, Scholkopf, & Wichmann, 2009). We point out that "String kernels," initially designed for protein function prediction and spam detection, are virtually identical to one contending proposal…

Lien, Mei-Ching; Ruthruff, Eric; Cornett, Logan; Goodin, Zachary; Allen, Philip A. – Journal of Experimental Psychology: Human Perception and Performance, 2008
The present study used event-related potentials (ERPs) to determine the degree to which people can process words while devoting central attention to another task. Experiments 1-4 measured the N400 effect, which is sensitive to the degree of mismatch between a word and the current semantic context. Experiment 5 measured the P3 difference between…

Besner, Derek; Borowsky, Ron – Psychological Review, 2006
This paper comments on the article by Plaut and Booth. Plaut and Booth's first simulation shows that there is essentially perfect discrimination between word and nonwords sharing the same orthographic structure when the simulation is carried out in the way we suggested. We take the view that Plaut and Booth's new simulation work settles little…

Lukatela, Georgije; Eaton, Thomas; Sabadini, Laura; Turvey, M. T. – Journal of Experimental Psychology: Human Perception and Performance, 2004
What form is the lexical phonology that gives rise to phonological effects in visual lexical decision? The authors explored the hypothesis that beyond phonological contrasts the physical phonetic details of words are included. Three experiments using lexical decision and 1 using naming compared processing times for printed words (e.g., plead and…

Silverman, Wayne P.; Ulatowski, Paul E. – Perceptual and Motor Skills, 1981
Two experiments examined the perceptual processing of letters embedded within one- and two-syllable words and visually similar nonwords. Results suggest that (1) the size of compelling perceptual units seems limited, and (2) unit size is not necessarily related to the correspondence between letter order and pronounceability.

Perfetti, Charles A.; Liu, Ying; Fiez, Julie; Nelson, Jessica; Bolger, Donald J.; Tan, Li-Hai – Bilingualism: Language and Cognition, 2007
Bilingual reading can require more than knowing two languages. Learners must acquire also the writing conventions of their second language, which can differ in its deep mapping principles (writing system) and its visual configurations (script). We review ERP (event-related potential) and fMRI studies of both Chinese-English bilingualism and…

Underwood, Benton J.; And Others – 1975
In an earlier study, subjects who were shown the two words "inside" and "consult" at two different points in a study list of two syllable words were willing to accept the word "insult" as having been on the study list. It was concluded that each syllable had a representation in memory over and beyond the semantic factors which are normally…

Stanners, Robert F.; And Others – Journal of Verbal Learning and Verbal Behavior, 1975
Describes an experiment measuring response latency which required subjects to make a word-nonword decision in response to a visually presented item. (AM)

Schvaneveldt, Roger W.; McDonald, James E. – Journal of Experimental Psychology: Human Perception and Performance, 1981
Earlier research with the lexical decision task led to the hypothesis that semantic context facilitates the encoding of words related to the context. Six experiments which employed different tasks (e.g., making a lexical decision) and different experimental paradigms (e.g., tachistoscopic exposures with masking stimuli) further investigated this…

Chastain, Garvin; And Others – 1981
The hypothesis that word context reduces visual rather than acoustic confusion between possible targets was tested in a series of experiments. All involved tachistoscopic presentation of letter strings followed by a pattern mask. Data from eight college students showed that target letters that are confusable only visually and acoustically…

Underwood, N. R.; McConkie, G. W. – 1983
A study investigated the size of the perceptual span within which adults use visual information to distinguish among letters as they read. The eye movements of fifteen college students were monitored as they read passages from a cathode-ray tube. On occasional fixations, letters in specified visual regions were replaced by other letters. The…

Theios, John; Amrhein, Paul C. – Psychological Review, 1989
A theory for the visual and cognitive processing, which accounts for slower naming of pictures than reading of words, is introduced. Two experiments assessed the differences distinguishing word reading and picture naming, using 58 undergraduates. The coding of the mind is neither intrinsically linguistic nor imagistic; it is abstract. (TJH)

Conners, Frances A.; Detterman, Douglas K. – American Journal of Mental Deficiency, 1987
Nineteen moderately/severely retarded students (ages 9-22) completed ten 15-minute computer-assisted instruction sessions and seven basic cognitive tasks measuring simple learning, choice reaction time, relearning, probed recall, stimulus discrimination, tachictoscopic threshold, and recognition memory. Stimulus discrimination, probed recall, and…
