Cognitive ability tests assess abilities involved in thinking e. Such tests pose questions designed to estimate applicants' potential to use mental processes to solve work-related problems or to acquire new job knowledge. Traditionally, the general trait measured by cognitive ability tests is called "intelligence" or "general mental ability. Some cognitive ability tests sum up the correct answers to all of the items to obtain an overall score that represents a measure of general mental ability.
Brain anatomy links cognitive and perceptual symptoms in autism
Brain anatomy links cognitive and perceptual symptoms in autism -- ScienceDaily
Several hypotheses attempt to explain the relation between cognitive and perceptual decline in aging e. Unfortunately, the majority of past studies examining this association have used correlational analyses, not allowing for these hypotheses to be tested sufficiently. This correlational issue is especially relevant for the information degradation hypothesis, which states that degraded perceptual signal inputs, resulting from either age-related neurobiological processes e. The reviewed evidence indicates the necessity to further examine the information degradation hypothesis in order to identify mechanisms underlying age-related cognitive decline.
Physical Load Affects Perceptual-Cognitive Performance of Skilled Athletes: a Systematic Review
Metrics details. Many researchers have considered the impact of physical exercise on perceptual-cognitive performance. There have also been a substantial number of studies that have examined how perceptual-cognitive skills differ between elite athletes and non-athletes. However, the knowledge on how physical exercise interacts with perceptual-cognitive skill is limited.
Published in the Journal of Neuroscience , the study identified a posterior region of the brain whose size -- amount of gray matter -- is related to both cognitive rigidity and overly stable visual perception, two symptoms of autism that until now were only conceptually related. Mental inflexibility is a hallmark symptom of autism spectrum disorder ASD. This is best seen in restricted and repetitive behaviors, which are required for an ASD diagnosis.
