This paper describes our efforts to model perceptual attention in virtual humans for the joint synthetic battlefield. With the exception of the work by Reece et al. [19,20] to develop individual combatants, current computer generated forces represent entities at the platform level, hence, the perceptual model of these entities is typically a composite representing the behaviors of multiple huma...

OBJECTIVE Psychostimulants are partially effective in reducing cognitive dysfunction associated with attention-deficit/hyperactivity disorder (ADHD). Cognitive effects of guanfacine, an alternative treatment, are poorly understood. Given its distinct action on α2A receptors, guanfacine may have different or complementary effects relative to stimulants. This study tested stimulant and guanfacine...

ISSUE Selective norepinephrine reuptake inhibitors such as atomoxetine increase both dopamine and norepinephrine in frontal cortex and may thereby enhance cognitive functioning in attention-deficit/hyperactivity disorder.

Clinical symptoms in multiple sclerosis include cognitive dysfunction. Difficulties in learning and remembering new information represent the most common cognitive deficit and are associated with a general and progressive brain pathology. Possible pathogenetic mechanisms for neuronal damage such as neuroprotective strategies are under active investigation also in experimental allergic encephalo...

OBJECTIVE Problems with inhibiting certain pathological behaviors are integral to obsessive-compulsive disorder (OCD), trichotillomania, and other putative obsessive-compulsive spectrum disorders. The authors assessed and compared motor inhibition and cognitive flexibility in OCD and trichotillomania for the first time, to their knowledge. METHOD The Stop-Signal Task and the Intradimensiona/E...

Recent meta-analytic evidence suggests that clinical neuropsychological methods are not likely to uncover circumscribed cognitive impairments in the deficit syndrome of schizophrenia. To overcome this issue, we adapted a cognitive neuroscience perspective and used a new "chaining" habit learning task. Participants were requested to navigate a cartoon character through a sequence of 4 rooms by l...

background and aim : )co-op( is a client-centered cognitive-based approach that focuses on individual abilities to achieve his/her functional goals. this approach is based on the assumption that cognition plays an important role in acquisition of functional skills, and is used to gain new skills and improve previous skills. the purpose of this paper is to systematically review studies on co-op ...

Parkinson's disease (PD) is a neurodegenerative condition that is associated with the depletion of dopamine (DA)-containing neurons in specific brain regions. This article reviews one consequence of this defect-sentence comprehension difficulty in nondemented patients with PD. The first section describes the pattern of cognitive deficits seen in patients with PD, focusing specifically on their ...

Objectives: Although it has been shown that there are more profound deficits present in deficit schizophrenia (DS) patients than in non-deficit schizophrenia (NDS) patients, there still remain some matters requiring further investigation. In this context, we formulated three research aims: (1) to compare executive functions between the investigated groups, (2) to determine the relationship betw...

BACKGROUND HIV associated neurocognitive deficit impairs motor activity, neuropsychiatric functioning, daily activity and work activity usually due to the immune suppression effect of the virus. Sub-Saharan region including Ethiopia is the region with the highest burden of HIV. However, a few studies are found on this aspect nationally. This study was aimed at determining the prevalence and the...
