This paper presents three studies which examine the susceptibility of sentence comprehension to intrusion by extra-sentential probe words in two on-line dual-task techniques commonly used to study sentence processing: the cross-modal lexical priming paradigm and the unimodal all-visual lexical priming paradigm. It provides both a general review…

A heterogeneous sample of infants with preterm histories and infants born full term participated in a study of declarative memory and rate of encoding, as measured in an imitation task and an examining task, respectively. Here we report the comparisons of the performances of infants born very preterm (27-34 weeks gestation) and moderately preterm…

Objective: The present study investigates whether there is an association between trait impulsivity in the normal population and inhibitory motor control as assessed by the stop task. Method: Low- and high-impulsive participants (as assessed by the I[subscript 7] questionnaire; both groups n = 31) performed the stop task. Differences in…

The present study was conducted to test predictions derived from the hypothesis that depression may serve the purpose of adaptively facilitating disengagement from obsolete cognitive plans. Groups of students with either low or high depression scores were contrasted using a procedure that featured an initial learning phase, within which…

Seven-year-olds completed a Posner cued attention task, under both neutral and affectively charged conditions. Compared to the traditional (affect-neutral) Posner task, performance in the affective Posner task was marked by dramatic decreases in reaction times (RTs), an increase in errors, an increased validity effect (difference in RTs to the…

This experiment tested whether children's insight into a difficult symbolic relation could be increased by explicitly emphasizing the intentionality surrounding the artifact's creation and use. Specifically, I explicitly emphasized (a) the adult's intent to communicate information via the artifact and (b) the artifact's intentional origins and…

In recent discussions about educational accountability, participants have joined one of two warring camps. In one corner are the advocates of results-driven accountability who claim that test scores are the most accurate measure of the quality of schools, teachers, and school leaders. In the opposite corner are the advocates of input-driven…

The transition from student to expert professional can be accelerated when a trajectory for change is plotted and made visible to learners. Trajectories or paths toward expertise are domain specific and must first be documented and then used within instructional contexts to promote knowledge transitions. This article describes how models of…

Internal working models of attachment (IWMs) are presumed to be largely "unconscious" representations of childhood attachment experiences. Several instruments have been developed to assess IWMs; some of them are based on self-report and others on narrative interview techniques. This study investigated the capacity of a self-report measure, the…

The ACTFL oral proficiency interview (OPI) and the Interagency Language Roundtable (ILR) scale provide both a testing method and a set of rating factors for evaluating proficiency. Both are closely related to actual language tasks identified as critical for government employees. Over time, the scale has been expanded to include four skills, a…

The language effects on repair strategies employed by 7 bilingual deaf children (native signers who also used spoken language) was examined. During two sessions--one conducted in sign language and the other in spoken language--each child described a picture. The examiner stopped the child twice to request clarification. The children's responses to…

Purpose: Corticomuscular electroencephalographic-electromyographic (EEG-EMG) coherence elicited by speech and nonspeech oromotor tasks in healthy participants and those with Parkinson's disease (PD) was examined. Hypotheses were the following: (a) corticomuscular coherence is demonstrable between orbicularis oris (OO) muscles' EMG and scalp EEG…

Four experiments investigated the impact of the lexical status of memory and processing stimuli on complex memory performance, with the aim of exploring mechanisms of interference in working memory. In a complex memory task, participants recalled words or nonwords while either monitoring words or nonwords for phonological content, or suppressing…

Several hypotheses related to Newman's (e.g., Patterson & Newman, 1993) response modulation hypothesis were examined among adolescents with attention-deficit/hyperactivity disorder (ADHD; n = 18) and normal controls (n = 23). Consistent with predictions, youth with ADHD committed more passive avoidance errors (PAEs) than controls during the latter…

In order to examine more closely the ways that children use socially constructed dialogue to mediate task mastery a hierarchical set of computer tasks were presented in an animated game format (ToonTalk) to three adult/child (US Kindergarten) dyads over five sessions. Transcriptions of the adult-child talk were used to determine (1) the types of…
