The prosodic aspects of hypokinetic dysarthria in Parkinson's disease (PD) have been the focus of numerous reports. Few data on the effects of levodopa on prosody, more specifically on the effects on the variability of prosodic characteristics such as pitch, loudness and speech rate, are available in advanced PD. The relation between these…

Background: Exposure to harsh parenting and children's skills in "Theory of Mind" (ToM) show independent and interacting associations with problem behaviors at age 2 (Hughes & Ensor, 2006). This study examined whether these age-2 measures also predict age-4 problem behaviors. Method: In a socially diverse sample (N = 120), multi-informant,…

Background: Attention-deficit/hyperactivity disorder (ADHD) is strongly influenced by heritability. Identifying heritable vulnerability traits (endophenotypes) that mark a relatively high risk of developing the disorder can contribute to the identification of risk genes. A fruitful area for the search for such endophenotypes may be motor control…

This study examined how seductive details affect on-line processing of a technical, scientific text. In Experiment 1, each sentence from the experimental text was rated for interest and importance. Participants rated seductive details as being more interesting but less important than main ideas. In Experiment 2, we examined the effect of seductive…

This study examined patterns of behavioral and emotional responses to conflict and cooperation in adolescents with anxiety/mood disorders and healthy peers. We compared performance on and emotional responses to the Prisoner's Dilemma (PD) game, an economic exchange task involving conflict and cooperation, between adolescents with…

Self-worth protective students characteristically perform poorly when they anticipate that poor performance is likely to reveal low ability, yet perform well in situations that involve little threat to self-worth. The present study sought a further understanding of this variable pattern of achievement, assessing two possibilities: (1) that the…

There is a common predicament faced by educational designers, that is, the lack of learning design tools for nontraditional pedagogies of learning. Because of this lack of alternatives, educational designers often use traditional design tools (such as task analysis) in contexts where nontraditional learning activities (such as collaborative…

Several visuo-motor tasks can be used to demonstrate biases towards left hemispace in schizophrenic patients, suggesting a minor right hemineglect. Recent studies in neglect patients used a new number bisection task to highlight a lateralized defect in their visuo-spatial representation of numbers. To test a possible lateralized representational…

Numerous studies show that children's language ability is related to false-belief understanding. However, there is considerable variation in the size of the correlation reported. Using data from 104 studies (N=8,891), this meta-analysis determines the strength of the relation in children under age 7 and examines moderators that may account for the…

Two tasks hypothesized to assess the efficiency of route selection were administered to 328 adults ranging from 18 to 93 years of age. Increased age was associated with slower completion of mazes, even after adjusting for differences in perceptual-motor speed, and with longer and less accurate routes in a task in which participants were asked to…

This study examined the relationships between metacognition, self-regulation and students' critical thinking skills and disposition in online Socratic Seminars for ninth grade World Geography and Culture students. Participants of this study came from six intact pre-AP (Pre-Advanced Placement) classes in a public high school in south central Texas…

Background: Children who meet language test criteria for specific language impairment (SLI) are not necessarily the same as those who are referred to a speech and language therapist. Aims: To consider how far this discrepancy reflects insensitivity of traditional language tests to clinically important features of language impairment. Methods &…

A comprehensive audit of the skills curriculum offered to students in a Bachelor of Laws program yielded important insights about the collective impact of assessment tasks on the hidden and operational skills curriculum. This qualitative case study supports the views (1) that assessment tasks provide significant skills practice and performance…

Among the challenges many teachers face in facilitating the improvement of speaking skills are sparing sufficient time for practice to enable students to achieve fluency in speaking through internalizing the structures, and establishing a balance between fluency and accuracy. This study aimed to seek an answer to the question as to whether…

In individuals with autism or autism-spectrum-disorder (ASD), conflicting results have been reported regarding the processing of biological motion tasks. As biological motion perception and recognition might be related to impaired imitation, gross motor skills and autism specific psychopathology in individuals with ASD, we performed a functional…
