Patients with conduction aphasia have been characterized as having a short-term memory deficit that leads to relative difficulty on span and repetition tasks. It has also been observed that these same patients often get the gist of what is said to them, even if they are unable to repeat the information verbatim. To study this phenomenon…

This study investigated the role of Voice Onset Time (VOT) as perceptual cue to the aspiration contrast of Cantonese initial stops produced by adolescent profoundly hearing impaired speakers. Speakers with normal hearing signalled the aspiration contrast through VOT differences. Hearing impaired speakers produced initial stops with no significant…

People with autistic spectrum disorders (ASD) have difficulties in recalling recently experienced events, which is dependent upon intact functioning of several aspects of "self awareness". The current study examined impaired episodic recall in ASD and its relationship to specific impairments in aspects of "self awareness". Between-group…

We evaluated a video-based error correction procedure for teaching four adults with developmental disabilities to set a table. Video clips were initially used as an antecedent prompt. However, only one of the adults learned to set the table with this procedure. Consequently, the remaining three adults received intervention in which the video clips…

Persons with and without mental retardation who were matched on CA took part in three tasks: an inhibition of return task, a location negative-priming task, and an identity negative-priming task. Having participants perform all three tasks allowed us to correlate performance among the tasks and assess the various relationships among performance…

In 6 task-cuing experiments, with 2 cues per task, the authors varied cue-stimulus interval to investigate G. D. Logan and C. Bundesen's (2003) claim that when cue repetition is controlled for, task-switch cost and its reduction with preparation are largely eliminated and hence cannot index an endogenous control process. Experiment 1 replicates…

In answering general-information questions, a within-person confidence-accuracy (C-A) correlation is typically observed, suggesting that people can monitor the correctness of their knowledge. However, because the correct answer is generally the consensual answer--the one endorsed by most participants--confidence judgment may actually monitor the…

Research on cognitive modeling of information search and Web navigation emphasizes the importance of "information scent" (the relevance of semantic cues such as link labels and headings to a reader's goal; Pirolli & Card, 1999). This article shows that not only semantic but also structural knowledge is involved in navigating the Web…

Purpose: To explore the sensitivity of children with specific language impairment (SLI) to amplitude-modulated and durational cues that are important for perceiving suprasegmental speech rhythm and stress patterns. Method: Sixty-three children between 7 and 11 years of age were tested, 21 of whom had a diagnosis of SLI, 21 of whom were matched for…

Three accounts of common ground maintenance make different assumptions about speakers' responsibilities regarding listener-privileged information. Duplicated responsibility requires each interlocutor to assimilate the other's knowledge before designing appropriate utterances. Shared responsibility appeals to least collaborative effort [Clark, H.…

Investigated the effect of phrase structure priming on sentence production latencies. Demonstrated the priming effects to be short lived. This finding contrasts with more persistent effects recently demonstrated in off-line picture description tasks. (Author/VWL)

In the voluntary task switching procedure, subjects choose the task to perform on a series of bivalent stimuli, requiring top-down control of task switching. Experiments 1-3 contrasted voluntary task switching and explicit task cuing. Choice behavior showed small, inconsistent effects of external stimulus characteristics, supporting the assumption…

High-stakes writing assessments currently exert a strong influence on the writing curriculum and instruction in schools across the United States. Under these circumstances it is important to examine the construct of writing competence on which these assessments are based, as well as the extent to which this construct supports the goals of…

Two experiments examined the dynamics of lexical activation in spoken-word recognition. In both, the key materials were pairs of onset-matched picturable nouns varying in frequency. Pictures associated with these words, plus two distractor pictures were displayed. A gating task, in which participants identified the picture associated with…

The authors tested source memory across three conditions, one in which 3 strongly associated primes of a target word were presented in the same source as the target, one in which primes were presented in a different source than the target, and one in which no associates of targets were encoded. In the first 2 experiments, target source memory…
