The effectiveness of five types of cognitive preparation on strength performance was examined in a 2 X 5 (Pre- and Posttest × Mental Preparation Condition) design, with repeated measures on pre-posttest. The mental preparation conditions were: arousal, attention, imagery, self-efficacy, and a control read condition. Immediately following the posttest trials, subjects completed a questionnaire measuring various cognitive states. The results showed that preparatory arousal and self-efficacy techniques produced significantly greater posttest strength performance than the control group. Analysis of the postexperimental questionnaire data suggested that a general effect of the preparation strategies used was to focus attention on the task to be performed. It was concluded that the effectiveness of a particular cognitive strategy may depend on the nature of the task to be performed and the particular aspects of the task to which attention is directed.

Experienced runners completed a Thoughts During Running Scale (TORS) immediately after a typical training run to assess the prevalence of certain thoughts during running. The Profile of Mood States (POMS) was also completed before and after the run. Confirmatory factor analyses revealed that a five-factor model provided better fit than simpler models. Items concerning the demands of the running activity and the monitoring of body responses loaded on one "associative" factor. The four "nonassociative" factors in this model were labeled Daily Events, Interpersonal Relationships, External Surroundings, and Spiritual Reflection. Correlational analyses indicated small but significant relationships between the TDRS dimensions and changes in mood. Increases in vigor were correlated with the tendency to engage in nonassociative thought, and decreases in tension and anxiety were found among those who thought about interpersonal relationships during the run. These results supplement findings on the effects of certain thought patterns during strenuous exercise.

The effect of exercise on cognitive performance in an older population was studied. Thirty sedentary men and women 65–72 years of age were randomly assigned to a walking group, a weight training group, or a placebo control group. Intervention groups exercised 30–60 min 5 days per week for 16 weeks, with the walking group training at 60% heart rate reserve, the weight training group employing the DAPRE method of weight progression, and the placebo control group engaging in mild range-of-motion and flexibility movements that kept their heart rates close to resting levels. At baseline and 16 weeks posttraining each subject completed the Ross Information Processing Assessment (RIPA), a maximal graded treadmill test, and a strength assessment of the knee extensors and elbow flexors. Sixteen weeks of walking improved VO2peak of the sedentary subjects 15.8%; VO2peak did not improve in the other two groups. Additionally, the RIPA scores of the walking group increased 7.5%, while those of the weight-training and control groups showed little change.

Several approaches have been taken to evaluate the effects of physical and mental training interventions on the mental abilities of older adults. A selective review of theory-based research suggests that older adults’ mental functioning may improve following both forms of training; however, the mechanisms that underlie these changes are not well understood. Several multidisciplinary approaches are evaluated that may help to explain how both exercise and mental training interventions may modify or offset age-related declines in mental abilities.

Processing efficiency theory predicts that anxiety reduces the processing capacity of working memory and has detrimental effects on performance. When tasks place little demand on working memory, the negative effects of anxiety can be avoided by increasing effort. Although performance efficiency decreases, there is no change in performance effectiveness. When tasks impose a heavy demand on working memory, however, anxiety leads to decrements in efficiency and effectiveness. These presumptions were tested using a modified table tennis task that placed low (LWM) and high (HWM) demands on working memory. Cognitive anxiety was manipulated through a competitive ranking structure and prize money. Participants’ accuracy in hitting concentric circle targets in predetermined sequences was taken as a measure of performance effectiveness, while probe reaction time (PRT), perceived mental effort (RSME), visual search data, and arm kinematics were recorded as measures of efficiency. Anxiety had a negative effect on performance effectiveness in both LWM and HWM tasks. There was an increase in frequency of gaze and in PRT and RSME values in both tasks under high vs. low anxiety conditions, implying decrements in performance efficiency. However, participants spent more time tracking the ball in the HWM task and employed a shorter tau margin when anxious. Although anxiety impaired performance effectiveness and efficiency, decrements in efficiency were more pronounced in the HWM task than in the LWM task, providing support for processing efficiency theory.

This research provides insight into the complex relationship between consumer response to persuasion attempts and skepticism, suggesting that erstwhile targets may be swayed by campaigns pitched as a form of entertainment. The authors examine consumer responses to an important sponsorship-leveraging tool: sponsorship-linked advertising (SLA). A theoretical model of consumer response to SLA is proposed, drawing on important resistance mechanisms to persuasion, including ad skepticism, attributed advertiser motives, and the nature of thoughts. Results confirm existing research on consumer skepticism suggesting its transitory nature and hence potential for advertisers to strategically temper it through specific cues in ad execution. Differential processing between SLA and traditional advertising is supported, such that SLA elicits more favorable cognitive response.

Two important questions are addressed in this article. The first concerns whether performance of well-learned skills is maintained as individuals grow older. The second question concerns whether older adults are able to acquire new skills. The answer to both questions is “yes”; however, the acquisition rate and the final performance level for newly acquired skills is generally less for older adults than for younger adults. The article resolves an apparent puzzle of how it is that older adults are capable of successful performance of everyday activities, given noted declines in cognitive-ability-type tasks shown for performance in laboratory studies. A brief discussion of age-related training strategies to enhance skill learning is provided.

The article provides a brief review of the literature on the relationship between aerobic Fitness and neurocognitive function, particularly as it relates to older adults. Cross-sectional studies provide strong support for the beneficial influence of fitness on neurocognitive function. The longitudinal or interventional literature, however, provides more equivocal support for this relationship. In discussing the literature, the authors introduce a new hypothesis, the executive control/fitness hypothesis, which suggests that selective neurocognitive benefits will be observed with improvements in aerobic fitness; that is, executive control processes that include planning, scheduling, task coordination, inhibition, and working memory will benefit from enhanced fitness. Preliminary evidence for this hypothesis is discussed.

Research suggests that there are differences in response time (RespT) as a function of age but that aerobic fitness might have a facilitatory effect on RespT. This study was designed to examine this relationship while addressing methodological issues from past research. Men from 3 age groups completed speeded tasks, a physical activity questionnaire, and an aerobic-fitness test. Results indicated that age has a negative impact on RespT (specifically premotor time and movement time). The interaction of aerobic fitness by age was also a significant predictor of RespT (specifically movement time) such that aerobic fitness was positively related to speed of performance for older participants. It is concluded that aerobic fitness might serve a preservative function for speeded tasks in older adults.

In developing a senior lecture for the 2014 national meeting of the North American Society for the Psychology of Sport and Physical Activity, I had the opportunity to reflect upon a career of research and to focus on three interesting questions that my colleagues and I have attempted to address. These questions have led to several studies that all revolve around identifying ways to increase the effects of exercise on cognitive performance. In particular, the questions examine the possibility of increasing effects by focusing on particular populations (e.g., older adults, children) and by increasing our understanding of dose-response relationships between exercise parameters (e.g., intensity, duration) and cognitive outcomes. I present empirical evidence relative to each of these questions and provide directions for future research on physical activity and cognitive functioning.
