regulation of behavior ( Chan, Shum, Toulopoulou, & Chen, 2008 ). Frequently, LDs are associated with weakness in EF domains, such as working memory ( Moll, Göbel, Gooch, Landerl, & Snowling, 2016 ), set shifting ( Sharfi & Rosenblum, 2016 ), sustained attention ( Ebert & Kohnert, 2011 ), discriminatory

A growing body of research has illuminated beneficial effects of a single bout of physical activity (i.e., acute exercise) on cognitive function in school-age children. However, the influence of acute exercise on preschoolers’ cognitive function has not been reported. To address this shortcoming, the current study examined the effects of a 30-min bout of exercise on preschoolers’ cognitive function. Preschoolers’ cognitive function was assessed following a single bout of exercise and a single sedentary period. Results revealed that, after engaging in a bout of exercise, preschoolers exhibited markedly better ability to sustain attention, relative to after being sedentary (p = .006, partial eta square = .400). Based on these findings, providing exercise opportunities appears to enhance preschoolers’ cognitive function.

improvements in selective attention and improved sustained attention skills. However, Chiesa et al. ( 2011 ) stated that many of the included studies have methodological limitations and also report negative results. The authors attribute this to possible differences in study design, study duration, and patient

The purpose of this study was to determine whether frontal midline theta activity (Fmθ), an indicator of top-down sustained attention, can be used to distinguish an individual’s best and worst golf putting performances during the pre-putt period. Eighteen golfers were recruited and asked to perform 100 putts in a self-paced simulated putting task. We then compared the Fmθ power of each individual’s 15 best and worst putts. The results indicated that theta power in the frontal brain region significantly increased in both best and worst putts, compared with other midline regions. Moreover, the Fmθ power significantly decreased for the best putts compared with the worst putts. These findings suggest that Fmθ is a manifestation of sustained attention during a skilled performance and that optimal attentional engagement, as characterized by a lower Fmθ power, is beneficial for successful skilled performance rather than a higher Fmθ power reflecting excessive attentional control.

We reviewed and summarize the extant literature on associative/dissociative cognitive strategies used by athletes and others in circumstances necessitating periods of sustained attention. This review covers studies published since a prior publication by Masters and Ogles (1998), and, in keeping with their approach, offers a methodological critique of the literature. We conclude that the distinction between associative and dissociative strategies has outlived its usefulness since initially proposed in an earlier era of ground-breaking research by Morgan and Pollock (1977) that was influenced to some extent by psychodynamic thinking. In recent years there has been an evolutionary shift in concepts of sustained attention toward mindfulness—moment-by-moment attention—that has had a significant impact on conceptual models and clinical practice in diverse areas including stress management, psychotherapy, and athletic performance. We propose that future research on cognitive activity in sustained performance settings be embedded in a mindfulness-based conceptual model.

Visual reaction time (RT) was measured in 10 older men (mean age, 71.1 years) and gender-matched controls (mean age, 26.3 years) when standing (single task) and when walking on a motor-driven treadmill (dual task). There were 90 quasirandomly presented trials over 15 min in each condition. Longer mean and median RTs were observed in the dual task compared to the single task. Older males had significantly slower mean and median RTs (315 and 304 ms, respectively) than the younger group (273 and 266 ms, respectively) in both task conditions. There were no age or condition effects on within-subject variability. Both groups showed a trend of increasing RT over the 90 single task trials but when walking only the younger group slowed. These novel findings demonstrate high but sustained attention by older adults when walking. It is proposed that the motor task’s attentional demands might contribute to their slower preferred walking speed.

To identify and characterize the scientific literature on the effects of exercise on Alzheimer’s disease, research was conducted in the following databases: MEDLINE, CINAHL, Web of Science, and Scopus. These MeSH terms—“exercise”, “motor activity”, “physical fitness”, “Alzheimer disease”, and its synonyms in English—were used in the initial search to locate studies published between 2003 and 2013. After reading the 12 final articles in their entirety, two additional articles, found by a manual search, were included. Of these, 13 had beneficial results of exercise in Alzheimer’s disease. Given the results discussed here, the exercise may be important for the improvement of functionality and performance of daily life activities, neuropsychiatric disturbances, cardiovascular and cardiorespiratory fitness, functional capacity components (flexibility, agility, balance, strength), and improvements in some cognitive components such as sustained attention, visual memory, and frontal cognitive function in patients with AD.

Sustained attention has been devoted to studying the factors that support (or thwart) individuals’ enjoyment of, interest in, and value judgments regarding their exercise activities. We employed a resistance-inducing (i.e., inoculation theory) messaging technique with the aim of protecting these desirable perceptions in the face of environmental conditions designed to undermine one’s positive exercise experiences. Autonomously motivated exercisers (N = 146, M age = 20.57, SD = 4.02) performed a 25-min, group-based, instructor-led exercise circuit, in which the activities were deliberately monotonous, and during which the confederate instructor acted in a disinterested, unsupportive, and critical manner. Shortly before the session, participants received either a control message containing general information about the exercise class or an inoculation message containing a forewarning about potential challenges to participants’ enjoyment/interest/value perceptions during the class, as well as information about how participants might maintain positive perceptions in the face of these challenges. Despite there being no between-conditions differences in presession mood or general exercise motives, inoculated (relative to control) participants reported greater interest/enjoyment in the exercise session and higher perceptions of need support from the instructor. Perceptions of need support mediated the relationship between message condition and interest/enjoyment.

Demands on concentrative and cognitive performance are high in sport shooting and vary in a circadian pattern, aroused by internal and external stimuli. The most prominent external stimulus is light. Bright light (BL) has been shown to have a certain impact on cognitive and physical performance.
To evaluate the impact of a single half hour of BL exposure in the morning hours on physical and cognitive performance in 15 sport shooters. In addition, courses of sulfateoxymelatonin (aMT6s), tryptophan (TRP), and kynurenine (KYN) were monitored.
In a crossover design, 15 sport shooters were exposed to 30 min of BL and dim light (DL) in the early-morning hours. Shooting performance, balance, visuomotor performance, and courses of aMT6s, TRP, and KYN were evaluated.
Shooting performance was 365.4 (349.7–381.0) and 368.5 (353.9–383.1), identical in both light setups. Numbers of right reactions (sustained attention) and deviations from the horizontal plane (balance-related measure) were higher after BL. TRP concentrations decreased from 77.5 (73.5–81.4) to 66.9 (60.7–67.0) in the DL setup only.
The 2 light conditions generated heterogeneous visuomotor and physiological effects in sport shooters. The authors therefore suggest that a single half hour of BL exposure is effective in improving cognitive aspects of performance, but not physical performance. Further research is needed to evaluate BL’s impact on biochemical parameters.
