The purpose of this research was to investigate the effects of the presence or absence of lyrics in children s musical selections on two types of young children's responses to music. Of additional interest were differences in responses due to subjects' ages and genders. Two studies were designed to compare responses to recorded lullabies with the melodies performed either by a woman singing the lyrics or by a solo instrument. In Study 1, a pictographic rating scale was used to obtain like-dislike responses to 10 music excerpts from 40 children, ages 4 and 5 years. Results of a three-way repeated-measures ANOVA indicated no significant differences due to the main effects of performance medium, age, or gender, with no significant interactions. Subjects for Study 2 were 51 preschool and kindergarten children. Each child individually listened to two pieces with lyrics and two without lyrics for as long as he or she chose, up to the compute duration of each piece. Time spent listening was recorded to the nearest second. Results of a three-way repeated-measures ANOVA indicated no significant differences due to the main effects of performance medium or song although girls did listen significantly longer than boys did. The results of both studies are consistent with the results of previous research indicating that young children s music attitudes and preferences do not seem to be based on specific musical characteristics and that children may have very idiosyncratic responses and listening styles. The use of time spent listening as a dependent measure for music preference is called into question.

Septal Perforations

Objective The purpose of this investigation was to determine the effect of septal perforations on posterior and anterior rhinomanometric measures of nasal resistance In an analog model. Design The data were analyzed using a repeated-measures ANOVA. Nasal resistance was the dependent variable, while type of rhinomanometry, septal perforation size, and position of resistance (proximal vs. distal) were nominal scale independent variables. Participants The analog model used in this study was similar to that described by Warren and Devereux (1966), except that the nasal cavities of the model were modified to create septal perforations. Outcome Measures The main dependent measure was nasal resistance. Results An important finding of this investigation was that septal perforations resulted in large differences (> 3 cm H2O/L/sec) between posterior and anterior nasal resistance values in the bilateral proximal resistor condition. Conclusions Anterior rhinomanometry may underestimate true nasal resistance when a septal perforation Is present, because the septal perforation prevents accurate measurement of nasopharyngeal pressure. Posterior rhinomanometric measures should accurately reflect nasal resistance despite septal perforations, because the perforation does not invalidate the estimate of nasopharyngeal pressure.

Background: Landing is a common movement that occurs in many sports. Barefoot research has gained popularity in examining how shoes alter natural movements. However, it is unknown how a single leg landing under barefoot conditions, as well as landing height, affects ground reaction forces (GRF). Objective: The purpose of this research was to examine the differences in GRF during a single leg landing under barefoot and shod conditions from various heights. Methods: Sixteen female Division II collegiate athletes, 8 basketball (age: 19.88 ± 0.64 yrs; height: 1.77 ± 0.09 m; mass: 75.76 ± 12.97 kg) and 8 volleyball (age: 20.00 ± 1.07 yrs; height: 1.74 ± 0.08 m; mass: 72.41 ± 5.41 kg), performed single leg landings from 12, 18, 24, and 30 inches barefoot and shod. An AMTI AccuGait force plate was used to record GRF. A 2 (condition) x 4 (box height) x 2 (sport) repeated measures ANOVA was performed to determine any GRF differences. Results: There were no significant three way or two-way interactions (p > 0.05). There was also no main effect for sport (p > 0.05). There were main effects for footwear and box height (p = 0.000) where shod (2295.121 ± 66.025 N) had greater impact than barefoot (2090.233 ± 62.684 N). Conclusions: Single leg barefoot landings resulted in less vertical GRF than shod landings. This could be due to increased flexion at the joints which aids in force absorption.

AbstractThe current study investigated body roll amplitude and timing of its peak in backstroke and compared them with front crawl swimming. Nineteen anatomical landmarks were digitised using 80 swimming trial videos (ten swimmers × two techniques × four intensities) recorded by two above- and four below-water cameras. One upper-limb cycle was analysed for each trial, and shoulder and hip roll, whole-body roll (WBR), and WBR due to the buoyant torque (WBRBT) were obtained. Main effects of intensity and technique on the amplitude and timing to reach the peak in those variables were assessed by two-way repeated-measures ANOVA. Swimmers decreased their WBRBT amplitude with an increase in the intensity in both techniques (p ≤ 0.005). The same result was observed for the amplitude of WBR, shoulder roll, and hip roll only in front crawl (p ≤ 0.017). Swimmers maintained the timing of peak WBRBT in both techniques, while they shifted the timing of WBR and hip roll peak toward the beginning of the cycle when increasing the intensity in front crawl (p ≤ 0.017). In conclusion, swimmers maintain the amplitude of WBR, shoulder roll, and hip roll in backstroke when the intensity increases, whereas they reduce the amplitude of all rolls in front crawl.

Background: To date, time-use studies in palliative care have been limited to exploration of time commitments of caregivers. Understanding time-use in people with a life-limiting illness might provide insight into disease progression, symptom management and quality of life. Aim: To determine the feasibility of a repeated-measures, time-use study in people with a life-limiting illness, and their primary caregivers, and to explore associations between time-use and perceived quality of life. Design: An observational repeated-measures feasibility pilot study. A priori criteria were established for study uptake (70%), retention (80%) and study value/burden (⩾7 Numerical Rating Scale 0–10). Burden and value of the study, use of time (Multimedia Activity Recall for Children and Adults with adjunctive accelerometry) and quality of life data (EuroQol-5 Dimension-5-Level Health Questionnaire and Australia-modified Karnofsky Performance Status scale) were assessed at time-points across five consecutive months. Setting/participants: People living with a life-limiting illness and caregivers recruited from Southern Adelaide Palliative Services outpatient clinics. Results: A total of 10 participants (2 caregivers and 8 people with a life-limiting illness) enrolled in the study. All but one of the criteria thresholds was met: 66% of participants who consented to be screened were enrolled in the study, 80% of enrolled participants ( n = 8) completed all assessments (two participants died during the study) and mean Numerical Rating Scale scores for acceptable burden and value of the study exceeded the criteria thresholds at every time-point. Conclusion: A repeated-measures time-use study design is feasible and was not unduly burdensome for caregivers and people living with a life-limiting illness.

Latent Curve

The use of latent curve models (LCMs) has increased almost exponentially during the last decade. Oftentimes, researchers regard LCM as a “new” method to analyze change with little attention paid to the fact that the technique was originally introduced as an “alternative to standard repeated measures ANOVA and first-order auto-regressive methods” (Meredith & Tisak, 1990, p. 107). In the first part of the paper, this close relationship is reviewed, and it is demonstrated how “traditional” methods, such as the repeated measures ANOVA, and MANOVA, can be formulated as LCMs. Given that latent curve modeling is essentially a large-sample technique, compared to “traditional” finite-sample approaches, the second part of the paper addresses the question to what degree the more flexible LCMs can actually replace some of the older tests by means of a Monte-Carlo simulation. In addition, a structural equation modeling alternative to Mauchly’s (1940) test of sphericity is explored. Although “traditional” methods may be expressed as special cases of more general LCMs, we found the equivalence holds only asymptotically. For practical purposes, however, no approach always outperformed the other alternatives in terms of power and type I error, so the best method to be used depends on the situation. We provide detailed recommendations of when to use which method.

Background. Exercise is increasingly becoming recognized as an important adjunct to medications in the clinical management of Parkinson’s disease (PD). Boxing and sensory exercise have shown immediate benefits, but whether they continue beyond program completion is unknown. This study aimed to investigate the effects of boxing and sensory training on motor symptoms of PD, and whether these benefits remain upon completion of the intervention. Methods. In this 20-week double-blinded randomized controlled trial, 40 participants with idiopathic PD were randomized into 2 treatment groups, (n = 20) boxing or (n = 20) sensory exercise. Participants completed 10 weeks of intervention. Motor symptoms were assessed at (week 0, 10, and 20) using the Unified Parkinson’s Disease Rating Scale (UPDRS-III). Data were analyzed using SPSS, and repeated-measures ANOVA was conducted. Results. A significant interaction effect between groups and time were observed F(1, 39) = 4.566, P = .036, where the sensory group improved in comparison to the boxing group. Post hoc analysis revealed that in comparison to boxing, the effects of exercise did not wear off at washout (week 20) P < .006. Conclusion. Future rehabilitation research should incorporate similar measures to explore whether effects of exercise wear off post intervention.

Metacognitive Instruction

This mixed-methods study investigated English-as-a-foreign-language (EFL) learners’ perceptions of task difficulty and their use of metacognitive strategies in completing integrated speaking tasks as empirical evidence for the effects of metacognitive instruction. A total of 130 university students were invited to complete four integrated speaking tasks and answer a metacognitive strategy inventory and a self-rating scale. A sub-sample of eight students participated in the subsequent interviews. One-way repeated measures MANOVA and structure coding with content analysis led to two main findings: (a) EFL learners’ use of metacognitive strategies, in particular, problem-solving, was considerably affected by their perceptions of task difficulty in completing the integrated speaking tasks; (b) EFL learners were not active users of metacognitive strategies in performing these tasks. These findings not only support the necessity of taking into account learners’ perceptions of task difficulty in designing lesson plans for metacognitive instruction, but also support a metacognitive instruction model. In addition, the findings provide empirical support for the utility of Kormos’ Bilingual Speech Production Model. As the integrated speaking tasks came from a high-stakes test, these findings also offer validity evidence for test development in language assessment to ascertain sustainable EFL learning for nurturing learner autonomy as an ultimate goal.

AbstractThe relationships among the time of imagery use on performance and self-efficacy in college baseball players during a hitting task was examined. Participants (n=24) were randomly assigned to one of three imagery conditions: (a) before practice, (b) during practice, (c) after practice. A one-shot MG-M imagery intervention was used. Results from a 3 (imagery group) ×2 (pretest and posttest) repeated measures ANOVA showed only a significant time by imagery group interaction for self-efficacy (F (2, 21)=4.67, p<0.05). These findings suggest that imagery had a stronger psychological effect than physical effect.

Factors of graphomotor skills may serve as indicators to determine a writer’s handwriting proficiency or acclimation to different writing surface textures. This study examines differences in children’s graphomotor skills based on types of writing medium and gender. Participants were 97 six-year-old Korean preschool children who had not received formal writing training prior to the study. Writing tasks were completed on a tablet screen and paper. Writing samples were analyzed using the Eye and Pen software to investigate spatial, temporal, and pressure exertion exhibited during the writing tasks. A repeated measures ANOVA revealed differences in graphomotor skills such as print size, writing speed, and writing pressure. Writing on a tablet screen decreased clarity of writing; print size and speed increased as the stylus slides across the tablet surface with relatively less friction, thereby decreasing the exertion of writing pressure. Analysis of writing differences according to gender indicated that boys generated larger print sizes than girls. Results suggest that while simple writing tasks may be feasible on the tablet screen, providing children with a larger writing medium and encouraging larger print sizes for writing practice, especially for boys, may be beneficial in the development of graphomotor skills among young learners.
