Is a Short Attention Span a Problem? How Do I Know if I Have a Low Attention Span? How Do I Train My Attention Span? Share In most cases a normal attention span for adults is approximately 15 to 20 minutes, though a lot depends on factors like subject matter, nature of the activity...
When compared to similarly educated, healthy younger participants, older participants had a shorter working memory span. The older adults did not demonstrate a different pattern of responding across tasks. However, the number of errors, perseverative errors, and the degree to which semantic clustering...
The purpose of this study was to determine whether reproducible normative values for hand dexterity and grip and pinch strength could be obtained in young children using simple tests that could be administered quickly within the attention span of a 3- to 5-year-old. The Functional Dexterity Test...
Trajectories of brain aging in middle-aged and older adults: Regional and individual differences The human brain changes with age. However, the rate and the trajectories of change vary among the brain regions and among individuals, and the reasons for ... N Raz,P Ghisletta,KM Rodrigue,... ...
psychological scaling has been discussed even for the basic numeral scale [51–57], unrelated to the measured/counted entity. This non-linear numerical mapping of estimates is quite general and depends on no training: it has been observed in monkeys, young children and adults with low training ...

3). As above, proteins were extracted from the frontal cortex of AD-DS and controls for AD-DS (C/AD-DS) and KIF5 family members, and fl-hAPP levels were evaluated by Western blotting (Table 2). Consistent with the fact that the majority of adults with DS show the increased expression...
However, other cortical regions did not overlap with brain regions that showed significant differences between East Asians and Caucasians in previous studies with young adults. Cortical anatomy is an important biomarker that reflects aging and neurodegenerative processes, and it has garnered attention as...
What makes for an excellent long weekend? In this case: Eleven kids. Thirteen adults. A ginormous mountain "cabinet" at the very tippy top of a loooong and winding and vertigo-inducing road along Grandfather Mountain in North Carolina. Copious amounts of bacon, bourbon, and twisted humor. Zi...
We investigated effects of normal variance in birth weight on MRI-derived measures of brain development in 628 healthy children, adolescents, and young adults in the large-scale multicenter Pediatric Imaging, Neurocognition, and Genetics study. This heterogeneous sample was recruited through geographically...
