Improving the acquisition and retention of a new motor skill is of great importance. The present study (i) investigated the effects of difficulty manipulation strategies (gradual difficulty), combined with different modalities of feedback (FB) frequency on performance accuracy and consistency when learning a novel fine motor coordination task, and (ii) examined relationships between novel fine motor task performance and executive function (EF), working memory (WM), and perceived difficulty (PD). Thirty-six, right-handed, novice physical education students volunteered to participate in this study. Participants were divided into three progressive difficulty groups (PDG), 100% visual FB (FB1), 50% FB (FB2), and 33% FB (FB3). Progressive difficulty was increased by the manipulation of the distance to the target; 2 m, 2.37 m, and 3.56 m. Three FB modalities were investigated (i.e.: 100% visual FB (100% FB), 50% reduced feedback condition (50% RFB), and 33% reduced feedback conditions (33% RFB)). Performance assessments were conducted following familiarization, acquisition, and retention learning phases. Two stress-conditions of dart throws were investigated (i.e.: free condition (FC) and time pressure condition (TPC)). After the learning intervention, data showed that, under the free condition, the 100% FB group had a significant improvement in accuracy during all learning phases. Under time pressure condition, for the 50% RFB and the 33% RFB group, the measured variable (accuracy and consistency) showed a significant linear improvement in performance. The association between the percentage of RFB frequencies and the task difficulty (50% group) may be a more appropriate and manageable cognitive load compared to the 33% RFB and the 100% FB group. The present findings could have practical implications for practitioners because, while strategies are clearly necessary for improving learning, the efficacy of the process appears to be essentially based on the characteristics of the learners.

This study investigated whether the use of a shoulder harness and team size would affect stretcher-carry performance, post-carry rifle marksmanship, and post-carry fine-motor coordination during a mass casualty simulation. Twelve male and eleven female soldiers volunteered. Soldiers carried stretchers in two- and four-person teams, with and without a shoulder harness in a 15-minute bout of rapid, short stretcher-carries and lifts. Soldiers completed as many carries as possible within the alloted period. Soldiers completed a marksmanship and fine-motor coordination task before and after each 15-minute period. Analysis of Variance and post hoc Newman-Keuls Comparison of Means revealed significant rifle shooting impairments after stretcher-carrying (p < 0.02). Men completed more carries than women (p < 0.0001), and more four-person hand carries were completed than other team size x harness combinations (p < 0.01). Women's rifle marksmanship was better when carrying in four-person teams (p < 0.05), while men's rifle marksmanship performance was not significantly altered. The fine-motor coordination task was completed faster after using a harness (p = 0.03) and working in four-person teams (p < 0.02). The ability to transport, medically treat, and protect patients is improved by working in four-person teams. In conclusion, for a mass casualty scenario, tactical planning should allow for enough soldiers to be deployed to allow stretcher-carrying in four-person teams. A harness system should be available for exigencies requiring two-person teams.

Many learning disabled students demonstrate psychological/behavioral and perceptual motor characteristics that affect physical education placement and programming. Among the characteristics exhibited by these students are hyperactivity, disorders of attention, impulsivity, poor self-concept, social imperception, delay in social play development, and deficiencies in body equilibrium, visual motor control, bilateral coordination, repetitive finger movements, and fine motor coordination. Activities found to benefit learning disabled students are jogging, relaxation, highly structured teacher-directed routines, and noncompetitive games, all of which must be carefully sequenced. Testing must be done to determine the type and extent of the learning disabled students’ problems, and activities must be selected on the basis of the results of such tests.

1504 Background: Few prospective trials have explored the neurocognitive impact of WBRT in BM patients (pts), complicated by competing effects between benefit from WBRT and deterioration due to disease progression. Methods: 208 pts from the WBRT alone arm (30 Gy) of a phase III trial (PCYC-9801) evaluating motexafin gadolinium in BM were analyzed. NCF was assessed by 8 tests of memory, executive function and fine motor coordination, and correlated to BM volume change by MRI, using Spearman’s rank correlation. Pts with tumor shrinkage below and above the median (45%) were compared for survival and NCF deterioration using Kaplan-Meier analysis. Results: 135 pts (65%) were evaluable for BM volume at baseline and 2 months (mo). Pts were divided into “good” and “poor” responders based on % volume reduction at 2 mo above or below the population median of 45%. The uni-directional hypothesis of improved survival in good responders was significant (P = 0.03, median survival (MS) 300±26 days (d) vs 240±19 d). For all 8 tests, the median time to NCF deterioration was longer in good responders than in poor responders. Largest gains were for an executive function test Trailmaking B (131 d gain, P=0.02), fine motor tests Pegboard non-dominant hand (110 d gain, P=0.05) and Pegboard dominant hand (93 d gain, P=0.02). In 15 mo survivors, statistically significant correlation between tumor shrinkage and NCF preservation was seen for 4/8 NCF tests (r = 0.68–0.88), especially for executive function and fine motor coordination. At early follow-up, the population mean NCF scores were dominated by pts with progressive disease, as reflected by a sharp drop in the mean NCF scores at 4 mo. 15-mo survivors had stable or improving scores, associated with greater reduction in BM volume in the 15 versus 4 mo survivors. Conclusions: WBRT-induced tumor shrinkage correlates with better survival and NCF preservation. NCF is stable or improved in long-term BM survivors. The adverse impact of tumor growth on neurocognitive function appears greater than that of WBRT. [Table: see text]
