ISLAMABAD: Older adults are more focused and perform better on cognitive tasks in the morning than in the afternoon, a new research has yielded.
The study conducted by a team of psychologists from Canada has identified differences in brain functions of older adults across the day, Press Tv reported.
Some 16 younger adults aged 19-30 and 16 older adults aged 60-82 were involved in the study.
They had to take a series of memory examinations during the afternoon from 1 to 5 pm, the study report appeared online in the journal Psychology and Aging.
The participants were evaluated via studying and recalling a series of picture and word combinations flashed on a computer screen.
The tests also included irrelevant words linked to certain pictures and irrelevant pictures linked to certain words flashed on the screen as a distraction.
“During the testing, the participants’ brains were scanned with fMRI which allows researchers to detect with great precision which areas of the brain are activated.”
The achieved data unveiled that older adults showed “substantially less engagement of the attentional control areas of the brain compared to younger ones.”
Testing 18 older adults during the morning time (8:30 am-10:30 am) showed their noticeably better performance comparing to the afternoon peers.
While, attending to fewer distracting items, older adults tested in the morning activated the same brain areas young adults did to successfully ignore the distracting information, according to two separate behavioral measures of inhibitory control.
“Their improved cognitive performance in the morning correlated with greater activation of the brain’s attentional control regions, the rostral prefrontal and superior parietal cortex, similar to that of younger adults,” said study lead author John Anderson, a PhD candidate with the Rotman Research Institute at Baycrest Health Sciences and University of Toronto.
