Objectives: To develop technical parameters for a videotape-based speed-of-processing training protocol, to evaluate the feasibility of self-administration (experiment 1), and to evaluate the protocol's effectiveness (experiment 2).
Design: A feasibility study (experiment 1) and a pre-post, 4-arm, nonrandomized controlled trial (experiment 2).
Setting: University research center.
Participants: A population-based sample (37 men, 47 women; age range, 65-94y) (experiment 1). A population-based sample (age > or =65y) with no prior exposure to the Useful Field of View assessment or speed-of-processing training, no dementia or life-limiting illness, a Mini-Mental State Examination score of greater than 24, corrected far visual acuity of greater than or equal to 20/40, contrast sensitivity of greater than or equal to 1.50 log(10), and deficient processing speed (experiment 2). For experiment 2, 8 of 189 eligible people declined to participate. The final sample for this experiment included 100 men and 81 women (age range, 65-91y).
Interventions: Eight to ten 1-hour cognitive training sessions.
Main Outcome Measure: Posttraining gains in processing speed.
Results: Self-administration was feasible. Subjects who underwent home-based training improved their processing speed significantly more than either control group (F(3,146)=16.16, P<.001). Their gains were 74% as great as the gains of those who underwent trainer-facilitated speed-of-processing training.
Conclusions: People can improve their processing speed at home using readily available technology. Future research should explore the relation of these improvements to driving performance.

Background: Sleep plays a crucial role in cognitive performance and cognitive changes in aging. In the current study, we investigated the role of sleep duration genetics in cognitive changes over time and the moderating effect of age.
Methods: Participants were drawn from the Reference Abilities Neural Network and the Cognitive Reserve studies of Columbia University.

Objective: Reading difficulties (RD) frequently co-occur with attention-deficit/hyperactivity disorder (ADHD), and children with both RD + ADHD often demonstrate greater challenges in reading and executive functions (EF) than those with RD-only.
Methods: This study examined the effect of a 4-week EF-based reading intervention on behavioral and neurobiological correlates of EF among 8-12 y.o.

Objective: Cognitive dysfunction is a prevalent and intricate manifestation of schizophrenia (SCZ) that may be associated with distinct clinical factors and the presence of antioxidants, which relationship is unclear. The study aimed to investigate cognitive function and its influencing factors in Chinese patients with SCZ.
Methods: A group of 133 patients with SCZ and 120 healthy controls (HCs) were recruited.

Background: Cognitive dysfunction is a persistent and difficult-to-treat symptom of major depressive disorder (MDD) and is receiving increasing attention. A balanced state of oxidative stress sustained by antioxidants is essential for normal functioning of brain, including learning capacity, emotional regulation, and cognitive function. The correlation between cognition and oxidative stress may also be altered in patients with mental disorders.

Background: The depression, obstructive sleep apnea and cognitive impairment (DOC) screen assesses three post-stroke comorbidities, but additional information may be gained from the time to complete the screen. Cognitive screening completion time is rarely used as an outcome measure.
Objective: To assess DOC screen completion time as a predictor of cognitive impairment in stroke/transient ischemic attack clinics.
