Young word learners fail to discriminate phonetic contrasts in certain situations, an observation that has been used to support arguments that the nature of lexical representation and lexical processing changes over development. An alternative possibility, however, is that these failures arise naturally as a result of how word familiarity affects…

Many important problems require consideration of multiple constraints, such as choosing a job based on salary, location, and responsibilities. We used the Remote Associates Test to study how people solve such multiply-constrained problems by asking participants to make guesses as they came to mind. We evaluated how people generated these guesses…

Studies have shown that prereaders find globally similar non-rhyming pairs (i.e., bell-ball) difficult to judge. Although this effect has been explained as a result of ill-defined lexical representations, others have suggested that it is part of an innate tendency to respond to phonological overlap. In the present study we examined this effect…

What is the relative salience of different aspects of word meaning in the developing lexicon? The current study examines the time-course of retrieval of semantic and color knowledge associated with words during toddler word recognition: At what point do toddlers orient toward an image of a yellow cup upon hearing color-matching words such as…

Using transcranial magnetic stimulation (TMS), motor evoked potentials (MEPs) were recorded from two antagonistic muscles, the first dorsal interosseus (FDI) of the hand and the extensor communis digitorum (EC) of the forearm. FDI is involved in grasping actions and EC in releasing. TMS pulses were delivered while participants were reading…

We investigated the neural basis of lexical access to written stimuli in adult dyslexics and normal readers via the Lexicality effect (pseudowords greater than words) and the Frequency effect (low greater than high frequent words). The participants read aloud German words (with low or high lexical frequency) or pseudowords while being scanned. In…

Written production studies investigating central processing have ignored research on the peripheral components of movement execution, and vice versa. This study attempts to integrate both approaches and provide evidence that central and peripheral processes interact during word production. French participants wrote regular words (e.g. FORME),…

Morphological and phonological processes are tightly interrelated in spoken production. During processing, morphological processes must combine the phonological content of individual morphemes to produce a phonological representation that is suitable for driving phonological processing. Further, morpheme assembly frequently causes changes in a…

The field of spoken language processing is concerned with creating computer programs that can understand human speech and produce human-like speech. Regarding the problem of understanding human speech, there is currently growing interest in moving beyond speech recognition (the task of transcribing the words in an audio stream) and towards…

Languages differ in how they package the components of an event into words to form sentences. For example, while some languages typically encode the manner of motion in the verb (e.g., running), others more often use verbs that encode the path (e.g., ascending). Prior research has demonstrated that children and adults have lexicalization biases;…

This study investigates "of"-constructions in the predicates of two reporting verbs, "demonstrate" and "show," in academic discourse. A construction perspective is taken to examine how the two predicate constructions (["demonstrate" N1 "of" N2] and ["show" N1 "of" N2]) would…

To clarify the link between anomalous letter processing and developmental dyslexia, we examined the impact of surrounding contours on letter vs. pseudo-letter processing by three groups of children--phonological dyslexics and two controls, one matched for chronological age, the other for reading level--and three groups of adults differing by…

Rumelhart and McClelland's chapter about learning the past tense created a degree of controversy extraordinary even in the adversarial culture of modern science. It also stimulated a vast amount of research that advanced the understanding of the past tense, inflectional morphology in English and other languages, the nature of linguistic…

This study investigates the effects of background knowledge on Chinese word processing during silent reading by monitoring adult readers' eye movements. Both higher knowledge (physics major) and lower knowledge (nonphysics major) graduate students were given physics texts to read. Higher knowledge readers spent less time rereading and had…

Previous text comprehension studies using the contradiction paradigm primarily tested assumptions of the activation mechanism involved in reading. However, the nature of the contradiction in such studies relied on validation of information in readers' general world knowledge. We directly tested this validation process by varying the strength of…
