The phrase "alertness change" is correct and usable in written English.
It can be used to describe a shift or variation in a person's state of alertness or awareness, often in contexts related to psychology, health, or performance.
Example: "The study aimed to measure the alertness change in participants after consuming caffeine."
Alternatives: "change in alertness" or "shift in awareness".
However, as there was no significant correlation between %CRs and alertness changes on either the 2- or 0-back task, the RTs may better reflect the influence of the ability to overcome sleepiness upon performance on the current WM tasks.
Activity in the right prefrontal cortex changed depending on alertness changes on the 2- and 0-back tasks independently, which indicates that activity in this region clearly reflects the ability to overcome sleepiness; it may contribute to the function of providing sufficient activity to meet the task load demands.
Similarly, there is a discrepancy between the subjective and objective assessment of the alertness changes in the daytime.
Because of the limited range of alertness changes in the daytime, a refined scale with several substages was used to score the subtle transitions between full alertness (sleep stage 0) and low alertness (sleep stage 1).
A score of 4 or more can be generated by the positive level of alertness or change items, or untestability on both cognitive items.
Even mild dehydration can have a negative impact on mental functions, from reduced concentration and alertness to changes in mood, researchers told The Daily Telegraph.
However, rate of chewing, flavor, or cognitive performance did not moderate the enhancement of alertness and changes in sustained attention by chewing gum, suggesting that greater motor activity does not exaggerate these effects.
Quantitative EEG analysis showed a higher state of alertness detected by changes in the central region, and peak frequency in the occipital region.
These suggested a "topography" or profile of alertness indicators and changes that were not evident through informal observations or indicated through historical proxy knowledge.
What is the clinical illness trajectory, and its impact, for children with non-curable, life-threatening conditions, specifically: pain, breathing or respiratory problems, feeding difficulties, alertness and interaction changes, sleep problems, seizures, constipation, and functional abilities?
