Task-oriented individuals believe capabilities can change and focus on learning, self-reference, mastery, personal improvement, and effort. Ego-oriented individuals believe capabilities are fixed and focus on performance, outcome, other-reference, and personal success. We examined the effects of task and ego orientations on the acquisition, retention, and transfer of a balance task. Eighteen acquisition trials with knowledge of results on a 40-s balance task (parallel stance) were performed. Retention and transfer (staggered stance) were administered 24 h later, with three no–knowledge of results trials each. Analyses showed that the high-ego-oriented individuals showed better balance on transfer than the low-ego-oriented ones, suggesting that those who score high in ego might be predisposed to use adaptive strategies to facilitate performance when feedback is withdrawn on learning tests. To test this hypothesis, the second experiment investigated the relationship between knowledge of results and goal orientations. Task, design, and procedure were identical to the first experiment. The analyses indicated that ego-oriented individuals were capable of sustaining balance for a much greater length of time on retention and transfer than task-oriented ones, mainly when knowledge of results was present on acquisition trials. This finding reinforces the advantage of ego over task goal orientation when learning a new motor task.

Although using a treadmill workstation may change the sedentary nature of desk jobs, it is unknown if walking while working affects performance on office-work related tasks.

Purpose:

To assess differences between seated and walking conditions on motor skills and cognitive function tests.

Methods:

Eleven males (24.6 ± 3.5 y) and 9 females (27.0 ± 3.9 y) completed a test battery to assess selective attention and processing speed, typing speed, mouse clicking/drag-and-drop speed, and GRE math and reading comprehension. Testing was performed under seated and walking conditions on 2 separate days using a counterbalanced, within subjects design. Participants did not have an acclimation period before the walking condition.

Results:

Paired t tests (P < .05) revealed that in the seated condition, completion times were shorter for mouse clicking (26.6 ± 3.0 vs. 28.2 ± 2.5s) and drag-and-drop (40.3 ± 4.2 vs. 43.9 ± 2.5s) tests, typing speed was greater (40.2 ± 9.1 vs. 36.9 ± 10.2 adjusted words · min−1), and math scores were better (71.4 ± 15.2 vs. 64.3 ± 13.4%). There were no significant differences between conditions in selective attention and processing speed or in reading comprehension.

Conclusion:

Compared with the seated condition, treadmill walking caused a 6% to 11% decrease in measures of fine motor skills and math problem solving, but did not affect selective attention and processing speed or reading comprehension.

Allowing self-control over various modes of instructional support has been shown to facilitate motor learning. Most research has examined factors that directly altered task-relevant information on a trial-to-trial basis (e.g., feedback). Recent research suggests that self-control (SC) effects extend to the manipulation of other types of factors (e.g., total number of practice trials completed). This research also illustrated that learners sometimes select a very small amount of practice when given latitude to do so. The purpose of the current study was to examine the effects of SC practice within a fixed time period on the learning of a basketball set shot. SC participants chose when to attempt each shot within two 15-min practice sessions, thereby controlling both the total number of shots taken and the spacing of shots. Yoked participants completed the same number of shots as their SC counterparts. Spacing of shots was also matched across groups. The SC group was more accurate and had higher form scores and longer preshot times during retention. These findings provided additional support for the generalizability of SC effects and extended prior research, showing that autonomy over total practice duration was not a prerequisite for the observed effects.

Undergraduate enrollments in kinesiology have grown over the past 20 years as the popularity of this major increased among students interested in the health professions. A panel discussion at the 2018 American Kinesiology Association workshop provided an overview of challenges facing kinesiology departments. Department leaders at four public universities discussed enrollment trends, faculty resources for teaching undergraduates, and budget models used at their universities. Comparisons were made with kinesiology departments at Big Ten universities to reflect more broadly on what is happening at U.S. public research institutions. At several universities, undergraduate kinesiology enrollments grew between 2008 and 2017, but at others, they leveled off or declined. In many cases, faculty resources have not kept pace with enrollments, leading to unhealthy student-to-faculty ratios. The panel discussed methods of coping with scarce resources for teaching undergraduates and how department leaders can use comparison data to stress the importance of adequate resources.

Falls in older adults are a public health challenge due to their influence on well-being and health-care costs. One way to address this challenge is to discover new methods to enhance postural control in older adults so they are better prepared to maintain an upright stance. Older and younger adults (N = 32) performed a static balance task on a force plate with no instructions, internal focus instructions, or external focus instructions. Center of pressure displacement time series were analyzed using sample entropy and standard deviation. Only the external focus condition significantly increased postural control entropy, which was observed across both age groups. This study showed that an external focus of attention can be used to increase postural control entropy within a single session of testing.
