WebApr 7, 2024 · This study aimed to enhance the real-time performance and accuracy of vigilance assessment by developing a hidden Markov model (HMM). Electrocardiogram (ECG) signals were collected and processed to remove noise and baseline drift. A group of 20 volunteers participated in the study. Their heart rate variability (HRV) was measured to … WebFeb 25, 2024 · Charge carrier dynamics and reaction intermediates in heterogeneous photocatalysis by time-resolved spectroscopies.

WebJan 25, 2024 · We then consider the cognitive and neurobiological theoretical underpinnings of the construct before providing a description of the various methods and metrics that have been used to compute measures of variability – reaction time cut-offs, raw and residualized intraindividual standard deviations, coefficient of variation, ex-Gaussian curve ... WebNov 1, 2024 · We found that the P600 amplitude was significantly larger during periods of low reaction time variability (high sustained attention) than in periods of high reaction time variability (low sustained attention). In contrast, the amplitude of the N400 was not affected by reaction time variability. high shoes women
The importance of intraindividual variation in reaction time
WebInhibition, memory, temporal discounting, decision-making, timing, and intraindividual variability in reaction time have emerged as key cognitive domains for understanding neurocognitive deficits in individuals with ADHD. In the domain of inhibition, motor inhibition has been studied most extensively, with deficits demonstrated in both ... WebJan 1, 2024 · Intraindividual variability is broadly defined as the fluctuation in an individual’s cognitive performance over time. This can refer to the moment-to-moment fluctuation in reaction time on a single task, variation across multiple tasks in a cognitive battery, or a single task repeated over a period of days, months, or years.
