BACKGROUND This study used a dual task design to investigate the effects of two different types of cognitive tasks on stability (as measured by center of pressure displacement) in young vs older adults with and without a history of falls. METHODS Two secondary cognitive tasks, a sentence completion and a visual perceptual matching task, were used to(More)
Prospective memory can be defined as the timely execution of a previously formed intention, and is critical in daily life because of its inherent involvement in goal-directed behavior. Cognitive systems involved in prospective memory have been hypothesized as involving the frontal cortex, and in adults, associated with working memory and executive(More)
The primary goal of this study was to examine whether children with ADHD have a true deficit in subjective time sense, or whether their impairment reflects a motivational deficit. Thirty children with ADHD and 30 matched control children completed two versions of a time reproduction paradigm ("Regular" and "Enhanced") in which motivational level was(More)
Virtual reality (VR) technology offers new opportunities for the development of innovative neuropsychological assessment and rehabilitation tools. VR-based testing and training scenarios that would be difficult, if not impossible, to deliver using conventional neuropsychological methods are now being developed that take advantage of the assets available(More)
BACKGROUND Magnetic resonance (MR) technology offers noninvasive methods for in vivo assessment of neuroabnormalities. METHODS A comprehensive neuropsychological/psychiatric battery, coupled with MR imaging, (MRI), MR spectroscopy (MRS), and functional MRI (fMRI) assessments, were administered to children with fetal alcohol spectrum disorders (FASD) to(More)
Magnetic resonance (MR) technology offers noninvasive methods for in vivo assessment of neuroabnormalities. A comprehensive neuropsychological/behavioral, MR imaging (MRI), MR spectroscopy (MRS) and functional MRI (fMRI) assessment was administered to children with fetal alcohol spectrum disorders (FASD) to determine whether global and/or focal(More)
Barkley (1997a) proposed that the central deficit in Attention Deficit Hyperactivity Disorder (ADHD) is in behavioral inhibition, resulting in deficits both in working memory and sense of time. To test this theory, 21 children with ADHD and a matched sample (ages 6-13) completed a variety of tasks that measured behavioral inhibition, working memory,(More)
BACKGROUND Clinical and research advancements in the field of fetal alcohol spectrum disorders (FASD) require accurate and valid identification of FASD clinical subgroups. OBJECTIVES A comprehensive neuropsychological battery, coupled with magnetic resonance imaging, (MRI), MR spectroscopy (MRS), and functional MRI (fMRI) were administered to children(More)
Although no Canadian studies have been conducted, studies suggest parents of children with autism experience difficulties obtaining a diagnosis for their child. Fifty-six parents of children with autism completed three questionnaires providing information on the families' demographics, parents' experiences throughout the diagnostic process, and their(More)
Persons with fetal alcohol syndrome (FAS) who are not mentally retarded often have difficulty qualifying for special educational and vocational services. In this pilot study, 16 nonretarded young adults with FAS were divided into two groups--one with average to above-average IQ and one with borderline to low-average IQ. Participants in both groups(More)
