Background: Cognitive health is a major concern for many people, and with potential benefits to academic and professional life, maximising cognitive performance is of interest far beyond the older demographics. Several natural products have been suggested as nootropics, including the herb sage. Previous assessments of various Salvia species have reported a range of effects on cognitive performance and mood in both older adult and younger adult populations. This study was conducted with SibeliusTM: Sage, an aqueous-ethanol extract of S. officinalis, to assess for the beneficial effects on cognitive performance in adolescents (12-14 year olds) and young adults (18-25 year olds). Methods and Findings: An acute, double-blind, placebo-controlled study was conducted with two single doses of SibeliusTM: Sage (150 mg and 300 mg). Cognitive performance was evaluated using CogTrackTM, which probes aspects of cognitive performance covering attention, working memory and episodic/declarative memory through a series of computer-based tasks. Consistent with previous study of SibeliusTM: Sage a significant effect was seen on the Immediate Word Recall task in young adults; suggesting acute treatment benefits to verbal episodic/declarative memory performance. Physiological effects of the treatment on salivary cortisol and oxytocin levels, as well as blood pressure and heart rate were also assessed, with limited evidence of an effect on these factors. No adverse events or side-effects linked to the study product intake was observed. The study was registered at the German Clinical Trials Register (DRKS-ID: DRKS00015716). Conclusions: A significant improvement due to the Sage extract was shown for a task assessing short-term episodic memory (Immediate Word Recall), supporting beneficial effects on cognitive performance in young adults that are consistent with previous reports in healthy older adults. These findings suggest that further investigation of the effects observed in this study in larger, long-term human volunteer studies could be beneficial to pursue.

Abstract The purpose of this study was to evaluate the capacity of three young adults with intellectual disability to independently operate a touch screen tablet, including examining their ability to navigate between three different menu screens, each with four different touch point options (branching and to access and complete multi-step tasks using video prompting. A multiple probe across subjects design was used and data were collected on these young adults' abilities to navigate between screens and perform steps for becoming more independent in cooking, cleaning, and folding tasks. All three participants learned to navigate between different menu screens, access different video programs, complete the multi-step tasks, and maintained skill performance from 10 to 61 days.

BACKGROUND: An understanding of how motor skill performance levels relate to energy expenditure (EE) is an important, yet relatively unexplored topic that may better inform physical activity interventions. AIM: This study examined the impact of motor competence (MC) on EE during the performance of object control skills in children and young adults. METHOD: Forty-two children (Mage 8.1 years) and 40 young adults (Mage = 23.4 years) completed sessions of throwing and kicking at varying intensity intervals. Polynomial regressions with response surface analysis were conducted to analyze the impact of process- and product-oriented MC levels on EE. RESULTS: Moderate positive associations among process-oriented motor competence levels and EE were demonstrated in all trial interval conditions with stronger associations shown for shorter trial intervals. CONCLUSION: Individuals’ movement quality (process) demonstrated greater associations with EE than performance product (speed), especially with higher intensity skill practice. These results provide additional evidence of the positive impact that MC has on the health benefits of physical activity, specifically during participation in activities that inherently require repeated performance of object control skills.

This study utilized two measures of job-related social behavior for adolescents and young adults—the Scale of Job-related Social Skill Knowledge (SSSK) and the Scale of Job-related Social Skill Performance (SSSP)—that had been developed in an earlier study. In the previous research, conceptually derived subsections of the two measures yielded high intercorrelations, suggesting the need to conduct further analyses to refine and possibly shorten both instruments. Both measures underwent item reduction analyses. After deleting 16 items a shortened SSSK contained 40 items. Factor analysis of the SSSP yielded six factors with a total of 94 items. Reliability analyses of the shortened SSSK and the six SSSP factors yielded acceptable results, and both measures powerfully discriminated among logically distinct subgroups. Logistic regression analyses identified those variables that discriminated most powerfully between persons with emotional and behavioral disorders and/or persons who had been arrested and persons without these characteristics. Results had implications for job-related social skills assessment and training and future research on the measures.
