Interrupted time-series (ITS) are often used to assess the causal effect of a planned or even unplanned shock introduced into an on-going process. The pre-intervention slope is supposed to index the causal counterfactual, and deviations from it in mean, slope or variance are used to indicate an effect. However, a secure causal inference is only…

Musical memory was tested in Alzheimer patients and in healthy older adults using long-term and short-term memory tasks. Long-term memory (LTM) was tested with a recognition procedure using unfamiliar melodies. Short-term memory (STM) was evaluated with same/different judgment tasks on short series of notes. Musical memory was compared to verbal…

Patients with semantic dementia (SD) make numerous phoneme migration errors when recalling lists of words they no longer fully understand, suggesting that word meaning makes a critical contribution to phoneme binding in verbal short-term memory. Healthy individuals make errors that appear similar when recalling lists of nonwords, which also lack…

Congenital amusia refers to a lifelong disorder of music processing and is linked to pitch-processing deficits. The present study investigated congenital amusics' short-term memory for tones, musical timbres and words. Sequences of five events (tones, timbres or words) were presented in pairs and participants had to indicate whether the sequences…

We investigated the effects of increased inter-hemispheric interaction (IHI) on five creativity dimensions (appropriateness, detail, categorical distinctiveness, fluency, and originality) of the Alternate Uses Task. Two methods were used to indicate degree of IHI. Trait IHI was indicated by individual differences in handedness, mixed-handers…

In 2 experiments, participants learned bone anatomy by using a handheld controller to rotate an on-screen 3-dimensional bone model. The on-screen bone either included orientation references, which consisted of visible lines marking its axes (orientation reference condition), or did not include such references (no-orientation reference condition).…

Recent reviews of evidence-based treatment for depression did not identify behavioral activation as an evidence-based practice. Therefore, this article conducted a systematic review of behavioral activation treatment of depression, which identified three meta-analyses, one recent randomized controlled trial and one recent follow-up of an earlier…

The purpose of this study was to evaluate the ability of individuals with spinal cord injury (SCI) to reach a training threshold during on-court sport activity. Monitors collected heart rate (HR) data every 5 s for 11 wheelchair tennis players (WCT) with low paraplegia and 11 able-bodied controls matched on experience and skill level (ABT).…

This study examined the differences in male and female students' perceptions of how much they had learned and how fairly their performance had been measured when choice between constructed response, selective response, or mixed testing formats was introduced into different classrooms. Results revealed that introducing assessment choice into a…

The main objective of this study was to unveil similarities and differences in the word reading strategies of orally raised individuals with prelingual deafness and hearing individuals. Relevant data were gathered by a computerized research paradigm asking participants to make rapid same/different judgments for words. There were three distinct…

There is considerable controversy as to whether there is an association between bowel disorders and autism. Using a bowel symptom questionnaire we compared 51 children with autism spectrum disorder with control groups of 35 children from special school and 112 from mainstream school. There was a significant difference in the reporting of certain…

Auditory brainstem evoked responses (ABRs) were compared in 15 newborns with Down syndrome and 15 sex-, age-, and weight-matched control newborns. Participants had normal ABRs based upon values specific to 32- to 42-weeks postconceptional age. Although Wave III and Wave V component latencies and the Wave I-III interpeak latency (IPL) were shorter…

Speed-accuracy trade-offs in persons with Down syndrome and typically developing controls were tested with a Fitts' task. Movement time scaled linearly with index of difficulty in both groups, and there were no accuracy differences. Persons with Down syndrome were slower than typically developing individuals. Regression analysis on movement time…

This study begins to explore ways in which the principles underpinning the traditional "nurture group" model could be altered and age ranges extended while continuing to deliver the proven success of nurture groups in promoting children's social and emotional development. Part-time nurture groups were established in four different primary schools…

A wide range of experimental studies have provided evidence that a night of sleep may enhance motor performance following physical practice (PP), but little is known, however, about its effect after motor imagery (MI). Using an explicitly learned pointing task paradigm, thirty participants were assigned to one of three groups that differed in the…
