Background. SuperUlam is a proprietary blend of natural ingredients aimed at supporting brain health. We aimed to evaluate the effect of SuperUlam on attention and mood in healthy adults.Methods. Twenty healthy individuals aged 35–65 were enrolled in this randomized, double-blind, placebo-controlled, crossover study. Study duration was 3 weeks and consisted of 3 visits. Measurement of cognitive function included computer-based testing of reaction time, complex attention, working memory, sustained attention, and executive functioning. Mood testing was performed via the profile of mood states (POMS) survey and the Chalder fatigue scale.Results. Cognitive function testing demonstrated a significant improvement from baseline in executive functioning, cognitive flexibility, reaction time, and working memory in the product group only (P<0.05). When comparing the study product to placebo, the data demonstrated a significant decrease in tension, depression, and anger (P<0.05). There was no significant difference between the product and placebo in the other measures of mood, including vigor, fatigue, confusion, and total mood disturbance. No adverse events were reported.Conclusions.Supplementation with SuperUlam is safe to consume with potential benefits to cognitive function and mood.

Self Schema

In the current study, we investigated the effects of gender and regular physical activity (PA) on PA decision-making and speed of information processing. We enrolled 110 university students ( Mage = 20.91, SD =2.28 years) in an experiment involving two tasks and a questionnaire. One of the two tasks assessed how much participants agreed with presented PA words and phrases and the other task predicted behavior and responses to future situations. We collected and measured the participants’ choices and the time they took to make them. The questionnaire, the International Physical Activity Questionnaire (IPAQ), consisted of exercise self-schema and PA questions. We conducted a 2 (gender: male or female) ×2 (regular PA or not) multivariate analysis of variance (MANOVA) and found statistically significant differences between variables as a function of participants’ gender (λ = .66, p < .001) and regular PA engagement (λ = .51, p < .001). In a regression analysis, we also found gender differences [males showed relationships between agreement with PA information and information processing speed for decisions on future behavior ( R 2 = .31, F = 12.50); females showed relationships between their exercise self-schema ( R 2 = .26, F = 18.18) and regular PA such that, in the non-regular PA group, exercise self-schema was related to reaction time in making decisions on future behavior ( R 2 = .29, F = 11.23), and in the regular PA group, agreement with PA information was related to reaction time for PA-related words, and agreement with non-PA information ( R 2 = .29, F = 8.91)]. These results highlight the need to consider participant characteristics when designing exercise interventions, and we present supplementary data regarding exercise self-schemas, decision-making, and the speed of processing PA information.

Time Parameters

Two reaction time tasks were compared as measures of information-processing speed. A multiple R between the WAIS—R Full, Performance, and Verbal scales and several reaction time parameters was calculated for 28 college students. Results indicate that the reaction-time task used in exploring the relationships between speed of information processing and IQ can be less complex than those used to date.

Processing Ability

It has become very popular to view the human as a processor of information, with reaction time (RT) used in various ways to measure the speed of information processing. In many sports quick decisions are essential to success. It is tempting to study reaction time, infer information-processing ability, and use the results to make predictions about success. The purpose of this study was to determine the relationship between various RT and movement time (MT) measures [simple RT, simple MT, simple total response time (TRT), choice RT, choice MT, choice TRT, and information-processing ability as determined by the increase in RT from simple to eight-choice conditions] with batting average, slugging percentage, and total average. 40 varsity baseball players from Colorado State University, University of Wyoming, University of Utah, and Brigham Young University were given 24 practice attempts followed by 48 experimental attempts for both simple and choice RT and MT. These scores were then correlated with batting averages, slugging percentages, and total averages. This research demonstrated no relationship between the various measurements of reaction and movement times and offensive ability in baseball.

Intellectually Gifted

In general, intellectually gifted children perform better than non-gifted children across many domains. The present validation study investigated the speed with which intellectually gifted children process information. 184 children, ages 9 to 13 years old (91 gifted, M age = 10.9 yr., SD = 1.8; 93 non-gifted children, M age = 11.0 yr., SD = 1.7) were tested individually on three information processing tasks: an inspection time task, a choice reaction time task, an abstract matching task. Intellectually gifted children outperformed their non-gifted peers on all three tasks obtaining shorter reaction time and doing so with greater accuracy. The findings supported the validity of the information processing speed in identifying intellectually gifted children.
