Neural response to rewards in youths with insomnia.

Study Objectives: Insomnia and depression are common comorbid conditions in youths. Emerging evidence suggests that disrupted reward processing may be implicated in the association between insomnia and the increased risk for depression. Reduced reward positivity (RewP) as measured by event-related potential (ERP) has been linked to depression, but has not been tested in youths with insomnia.

Altered brain activity related to inhibitory processing in youth with insomnia.

Insomnia has been shown to negatively affect one's cognitive functioning. While there has been some evidence suggesting sleep disruption in relation to impaired inhibitory control, a major component of executive function, little is known about the underlying neural processing in insomnia. The current study aimed to examine the differences in the behavioral responses and electroencephalography (EEG) correlates of inhibitory control between youths with insomnia and healthy sleepers.

Effects of insomnia symptoms and objective short sleep duration on memory performance in youths.

Sleep quantity and quality are both important for optimal development and functioning during youth. Yet few studies have examined the effects of insomnia symptoms and objective short sleep duration on memory performance among adolescents and young adults. One-hundred and ninety participants (female: 61.

Associations of weekday-to-weekend sleep differences with academic performance and health-related outcomes in school-age children and youths.

Weekday-to-weekend sleep discrepancy is a common phenomenon in school-age children and youths. However, the effects of weekday-to-weekend sleep differences remain unclear. A systematic review that included 72 observational studies was conducted to examine the association of weekday-to-weekend differences in bedtime, rise time, mid-point of sleep and sleep duration with academic performance and health-related outcomes in children and youths.

Association of Sleep and Circadian Activity Rhythm with Emotional Face Processing among 12-month-old Infants.

Sleep and circadian rhythmicity both play an important role in human's cognitive functioning, yet the way in which early development of sleep and circadian rhythm affects cognitive processes and social learning in infants remains less understood. We examined the association of sleep and circadian activity rhythm (CAR) with face and emotional information processing in 12-month old infants. Face processing was measured by eye tracking, whereby infants' scanning patterns and pupil dilations were calculated when they were presented with neutral, pleasant and unpleasant faces.
