Deaf and hearing college students' mean reaction times (RTs) were compared on a mental calculation task in which they had to verify the accuracy of solutions to addition and multiplication problems. The deaf students were divided into higher and lower readers. Higher deaf readers and hearing students had similar RTs and accuracy on addition…

Four experiments investigate the differences between implicit and explicit sequence learning concerning their resilience to structural and superficial task changes. A superficial change that embedded the SRT task in the context of a selection task, while maintaining the sequence, did selectively hinder the expression of implicit learning. In…

The effect of increasing the number of stimuli to be recalled was investigated to evaluate whether sensitivity for memory impairment was enhanced in adults with Down syndrome when using higher task load. Three levels of load were compared across three groups of adults: those with cognitive deterioration, no cognitive deterioration over age 40, and…

This study compared the oral structure and oral-motor skills of 59 boys with fragile X syndrome (FXS), 34 boys with Down syndrome (DS), and 36 developmentally similar typically developing (TD) boys. An adaptation of the J. Robbins and T. Klee (1987) Oral Speech Motor Protocol was administered to participants and their scores on measures of oral…

As engineers contribute to solving the increasingly complex problems facing our society, there is a growing need for the engineers graduating from undergraduate programs to deeply understand the context within which they are solving problems. There is a particular need for engineers who recognize the complexities of global and societal issues and…

This study reports the results of a picture verification task assessing the interpretation of intra-sentential anaphora and cataphora in Italian by a group of English-Italian bilingual eight-year-olds, a group of age-matched Italian monolinguals, and a group of Italian monolingual adults. No significant differences between the groups were observed…

Reports on a study that investigated differences in reading strategies between good and poor young readers in their use of linguistic context, in particular whether good readers make better use of succeeding context by using a better strategy or whether they read better simply because of superior knowledge. (Author/JL)

Examines task-based, synchronous computer-mediated communication (CMC) among intermediate learners of English. Explores whether learners engage in negotiated interaction when they encounter new lexical items, whether task type has an effect on the amount of negotiation that transpires, and how this CMC negotiation compares to that noted in the…

Native and experienced nonnatives listened to a text while performing a concurrent task. Half of each group was given the topic of the passage. Scores on the concurrent task were compared with baseline to index working memory (WM) consumption. Results showed greater WM consumption for nonnatives than natives when the topic was unavailable,…

We investigate the effects of cueing, in a multimedia programme for the individualized training of the whole task to prepare a plea, on the learning outcomes of 43 sophomore law students. The cueing formats of worked-out examples (WOEs), process worksheets (PWs), and both WOE and PW are compared to a no-cueing control condition. Our hypotheses…

The purpose of this experiment was to compare components of the human and rat auditory event-related potential (ERP) in a serial feature-positive discrimination task. Subjects learned to respond to an auditory target stimulus when it followed a visual feature (X [right arrow] A+), but to not respond when it was presented alone (A-). Upon solving…

The "perceptual loop theory" of speech monitoring (Levelt, 1983) claims that inner and overt speech are monitored by the comprehension system, which detects errors by comparing the comprehension of formulated utterances to originally intended utterances. To test the perceptual loop monitor, speakers named pictures and sometimes attempted to halt…

Background: The existing literature has conflicting findings about the literacy outcome of children with speech sound disorders (SSD), which may be due to the heterogeneity within SSD. Previous studies have documented that two important dimensions of heterogeneity are the presence of a comorbid language impairment (LI) and the persistence of SSD,…

Profiles of verbal learning and memory performance were compared for typically developing children and for four developmental disorders characterized by different patterns of language functioning: specific language impairment, early focal brain damage, Williams Syndrome, and Down Syndrome. A list-learning task was used that allowed a detailed…

Negative priming refers to slowed down reactions when the distractor on one trial becomes the target on the next. Following two popular accounts, the effect might be due either to inhibitory processes associated with the frontal cortex, or to an ambiguity in the retrieval of episodic information. We used event-related brain potentials (ERPs) to…
