(1) Background: How to optimally promote the process of acquiring and learning a new motor skill is still one of the fundamental questions often raised in training and movement science, rehabilitation, and physical education. This study is aimed at investigating the effects of differential learning (DL) and the elements of OPTIMAL theory on learning a goal-kicking skill in futsal, especially under the conditions of external and internal foci. (2) Methods: A total of 40 female beginners were randomly assigned to, and equally distributed among, five different interventions. Within a pretest and post-test design, with retention and transfer tests, participants practiced for 12 weeks, involving two 20-min sessions per week. The tests involved a kicking skill test. Data were analyzed with a one-way ANOVA. (3) Results: Statistically significant differences with large effect sizes were found between differential learning (DL) with an external focus, DL with an internal focus, DL with no focus, traditional training with an external focus, and traditional training with control groups in the post-, retention, and transfer tests. (4) Conclusions: The results indicate the clear advantages of DL. It is well worth putting further efforts into investigating a more differentiated application of instructions combined with exercises for DL.

The purpose of this study was to determine if an external attention focus was more effective than an internal attention focus for college female volleyball players practicing the complex open skill of the jump float serve. Sixteen college females with prior competitive volleyball playing experience were matched into either an internal or external attention focus group, each serving a total of 30 balls in three blocks of ten serves. After the pre-test, two days of practice and day off, a post-test was conducted for both groups. Results demonstrated a 25% improvement for the internal focus group and a 26.8% improvement for the external focus group. These results suggest that both internal and external focuses of attention are beneficial for practicing the complex jump float serve. However, a paired t-test from the improvement scores of both groups demonstrated no significant difference between the two practice conditions suggesting that either an internal focus or an external focus of attention is effective for practicing the complex jump float serve. In this particular study, external focus of attention was not found to be more effective than an internal focus of attention. Since these results do not support much of the research done with attention focus and sport skills, additional studies are needed comparing internal and external focus of attention, especially when practicing open sport skills.

A test for comparing linear contrasts with heteroscedasticity, both across components of each contrast and between the contrasts, is developed under assumption of normality. The test is based on the weighted sums of squares. This is an extension of methods for weighted one-way ANOVA developed in Welch (1951) under the null, and in Kulinskaya et al. (2000) [12] underthe alternatives. We provide very accurate approximations to the null distribution and to the distribution under alter natives. The quality of these approximations is studied by simulation. The main application is the I by 2 layout which is widespread in meta-analysis. Our methods allow the homo-geneity of effect sizes across I studies to be tested, without the assumption of equal variances in the treatment and the control groups.

SummaryStudy aim: External focus of attention is considered as a critical factor in the OPTIMAL theory of motor learning. This theory proposes that external focus of attention facilitates motor performance and learning because it promotes focusing on the task goal. However, the effects of external focus of attention on focusing on the task goal are not well understood. The aim of this study was, therefore, to investigate the effects of an external focus of attention versus an internal focus of attention on motor learning and promoting focus of the learner on the task goal.Material and methods: Thirty-six right-handed male students (mean age 21.16 ± 1.85 years old) with no prior experiences with the motor task were randomly assigned to three groups: external focus, internal focus, and control groups. Participants were asked to throw darts at a target during an acquisition phase (10 blocks of six trials each) and during subsequent retention and transfer tests. Throwing accuracy and focus on the task goal were measured as dependent variables. Analysis of variance (ANOVA) with repeated measures as well as a one-way ANOVA was used to analyze the differences in accuracy scores between groups during the acquisition phase as well as retention and transfer tests, respectively. The significance level was set at p < .05. The author supervised all phases of the experiment.Results: The results showed that adopting an external focus promoted a focus on the task goal and resulted in significantly better motor learning than adopting an internal focus and control conditions (p < 0.05).Conclusions: The findings of the present study provided support for the propositions of the OPTIMAL theory and showed that adopting an external focus of attention promotes focus of the learner on the task goal. The results are discussed in terms of benefits of external focus instructions for facilitating motor learning and goal-action coupling.

SummaryStudy aim: The purpose of this study was to examine the effects of adopting an external focus of attention on motor learning among girls with ADHD aged seven and eleven years.Material and methods: Twenty-four seven-year-old and 24 eleven-year-old female children with symptoms of ADHD were randomly assigned to groups receiving either external focus of attention (EXT) instructions or internal focus of attention (INT) instructions, making four experimental groups: EXT-7, INT-7, EXT-11, and INT-11. Participants performed a pretest followed by five training blocks under an external or internal instruction and were then given a retention test one day later. After training, we employed a manipulation check to verify the children’s type and intensity of focus.Results: Adopting an external focus of attention, compared to an internal focus of attention, led to better motor learning among girls with ADHD (F1, 44 = 5.08, p = 0.029, η2 = 0.10). In addition, adopting an external focus of attention reduced the children’s tendency to focus on self. Older children performed better than younger children in balance time (F1, 44 = 16.10, p < 0.001, η2 = 0.26).Conclusions: Our results indicate that propositions of the OPTIMAL theory can be extended to children with ADHD.

AbstractThe penalty kick is of great importance in the sport of soccer. Therefore, the aim of this study was to test predictions of the OPTIMAL theory and identify key attentional and motivational factors that impact the accuracy of the penalty kick. The following six groups of skilled participants performed penalty kicks following instructions that directed their focus of attention or impacted their autonomy support: external focus with autonomy support (EF/AS), external focus alone (EF), internal focus with autonomy support (IF/AS), internal focus alone (IF), autonomy support alone (AS) and control (C) groups. The analysis showed that the EF/AS group demonstrated better kicking accuracy relatively to the IF/AS, IF and C groups, but there were no significant differences between the EF/AS and EF or AS groups. Interestingly, the EF/AS group showed higher self-efficacy compared to the EF, IF/AS, IF and C groups. The finding suggest that a combination of attentional and motivational factors may produce benefits in motor performance.

Abstract. In a recent paper, Ferrer and Pardo (2014) tested several distribution-based methods designed to assess when test scores obtained before and after an intervention reflect a statistically reliable change. However, we still do not know how these methods perform from the point of view of false negatives. For this purpose, we have simulated change scenarios (different effect sizes in a pre-post-test design) with distributions of different shapes and with different sample sizes. For each simulated scenario, we generated 1,000 samples. In each sample, we recorded the false-negative rate of the five distribution-based methods with the best performance from the point of view of the false positives. Our results have revealed unacceptable rates of false negatives even with effects of very large size, starting from 31.8% in an optimistic scenario (effect size of 2.0 and a normal distribution) to 99.9% in the worst scenario (effect size of 0.2 and a highly skewed distribution). Therefore, our results suggest that the widely used distribution-based methods must be applied with caution in a clinical context, because they need huge effect sizes to detect a true change. However, we made some considerations regarding the effect size and the cut-off points commonly used which allow us to be more precise in our estimates.

The component of antenatal care received by pregnant women is classified as incomplete because the implementation of standard pregnancy services is still using conventional methods. There are obstacles faced by midwives, such as the limited time in a recording, which has an impact on the declining quality of antenatal care standards. This research aims to compare the effectiveness of the use of KIA books and MONSCA applications in midwives in the application of the standard Antenatal service 14 T. This research was conducted in Puskesmas Tanete and Puskesmas Bontobangun Bulukumba District. The method used in the study is experimental quasi (pre-test post-test nonequivalent control design). Using a sample of midwives in this study, as many as 36 people were divided into two groups (18 intervention groups and 18 control groups). The sampling technique in this study used purposive sampling. Data were analyzed using the Mann-Whitney Test. The results showed that there was a difference in the effectiveness of using KIA books with MONSCA applications, MOSCA's applications were easier to use, faster, safer, and more accurate than KIA books. It can be concluded that the MONSCA application is more effective than KIA books. Key words: Effectiveness, Android-based Smart Continuity of Care application, KIA book, Antenatal service 14 T
