Social media applications such as Facebook have received wide attention in their use in education. However, it is still hard to arrive at a conclusion regarding whether a Facebook-assisted approach is effective in education and whether there are any significant gender differences in the learning outcomes. Based on rigid inclusion criteria, this study included 21 peer-reviewed high-quality journal articles. Through a meta-analysis using Reviewer Manager 5.3, the authors concluded that a Facebook-assisted approach could obtain significantly higher learning outcomes than the non-Facebook-assisted one with a medium effect size (d = 0.42) and that females could achieve significantly better learning outcomes than males with a very small effect size (d = -0.21) in the Facebook-assisted education. Future research could examine the effect of educational use of other social media applications, as well as in sociological, psychological, or educational dimensions.

Meta Analyses

Despite of several meta-analyses indicating that exposure-based treatments (EBT) are successful in addressing anxiety and fear symptoms, less is known whether this is also the case for disgust, which also accompanies anxiety disorders. Therefore, the aim of the current meta-analysis was to compare the efficacy of EBT on disgust and anxiety (emotional distress), against control condition. This meta-analysis included a total of eight studies. Overall, there was a medium effect size (g = .57, 95% CI: .26 to .88, p < .001) for emotional distress; a medium effect size for anxiety (g = .79, 95% CI: .24 to 1.34, p = .005), yet a small effect size for disgust (g = .36, 95% CI: .05 to .68, p = .024). These findings prompt that current EBT are not tailored to address disgust symptoms accompanying many forms of anxiety disorders, although literature points more and more to a need in this respect. We also examined potential moderator variables (the year of publication, the number of exposure sessions, age of the sample, and gender composition). Additionally, we discussed several strengths and limitations, one of the most important being the small number of studies regarding the subject and their heterogeneity.

In this COVID-19 pandemic, learners across the world are encouraged to stay at home receiving online education, which has nearly caused various learning outcomes. It is thus necessary to analyze online learning outcomes, as well as their gender differences to provide constructive references for learners, teachers, and technology developers. This study obtained reliable data from various databases using searching techniques. The study also selected the research articles based on inclusion and exclusion criteria. After analyzing the forest and funnel plots drawn via Review Manager 5.3, the study arrived at the conclusion that online learning outcomes were significantly higher than the traditional learning outcomes with a large effect size (d = 1.24), while the gender differences in learning outcomes were not significant with a small effect size (d = -0.03). In the future, experts could make every effort to develop advanced emotion detection applications via interdisciplinary cooperation to improve online learning outcomes.

Objective To evaluate the evidence from randomised controlled trials (RCTs) and quantify the effects of acupressure on anxiety among adults. Methodology RCTs published between January 1997 and February 2014, comparing acupressure with sham control, were identified from the databases Science Citation Index/Social Sciences Citation Index, Scopus, PubMed and PsycINFO. Meta-analysis of eligible studies was performed and the magnitude of the overall effect size was calculated for the anxiety outcome. Revised STRICTA (the Standards for Reporting Interventions in Clinical Trials of Acupuncture) criteria were used to appraise the acupressure procedures, and the Cochrane risk of bias tool was used to assess the methodological quality of the studies. Results Of 39 potentially relevant studies, seven RCTs met the inclusion criteria for review while five studies met the criteria for meta-analysis. All studies reported the positive effect of acupressure on relieving anxiety from the anticipation of surgery or treatment. EX-HN3 ( Yintang), HT7 ( Shenmen) were the commonest points selected and two studies used bilateral points. The acupressure procedure was generally well reported and studies had a low risk of bias. The combined results of the five trials showed a greater overall reduction in anxiety in the acupressure group than in the sham controls (standardised mean differences (SMD)=−1.11; 95% CI −1.61 to −0.61; p<0.0001 heterogeneity: I2=75%; χ2=16.17; p=0.003; r=0.485). Conclusions Acupressure seems to be effective in providing immediate relief of pretreatment anxiety among adults, and has a medium effect size. However, conflicting results were found for the improvements on physiological indicators. More rigorous reporting, including allocation concealment procedure, is needed to strengthen the results.

the visual component of music performance as experienced in a live concert is of central importance for the appreciation of music performance. However, up until now the influence of the visual component on the evaluation of music performance has remained unquantified in terms of effect size estimations. Based on a meta-analysis of 15 aggregated studies on audio-visual music perception (total N = 1,298), we calculated the average effect size of the visual component in music performance appreciation by subtracting ratings for the audio-only condition from those for the audio-visual condition. The outcome focus was on evaluation ratings such as liking, expressiveness, or overall quality of musical performances. For the first time, this study reveals an average medium effect size of 0.51 standard deviations — Cohen's d; 95% CI (0.42, 0.59) — for the visual component. Consequences for models of intermodal music perception and experimental planning are addressed.

Abstract Objective A previous meta-analysis utilized the Trail Making Test A (TMT-A) to measure the impact of heart failure (HF) on attention. A near medium effect size with moderate heterogeneity was observed, the HF group performed worse than healthy controls (HC). This study explores if the age of the HF group moderates differences in the performance of individuals with HF versus HC on TMT-A. Data Selection Two researchers searched eight databases, extracted data, and calculated effect sizes as part of a larger study. Inclusion criteria were: (a) adults with HF (New York Heart Association severity II or higher), (b) comparison to a HC group, (c) standardized neuropsychological/cognitive testing, and (d) adequate data to calculate effect sizes. Exclusion criteria were: (a) participants had other types of major organ failure, (b) the article was not in English, or (c) there was a risk of sample overlap with another included study. A total of six articles were included in this sub-study (Total HF n = 602 and HC n = 342). The unrestricted maximum likelihood computational model was used for the meta-regression. Data Synthesis Studies included in the meta-regression evidenced a statistically significant medium effect size estimate with moderate heterogeneity (k = 6, g = 0.636, p &lt; 0.001, I2 = 56.85%). The meta-regression was statistically significant (slope = −0.0515, p = 0.0016, Qmodel = 9.86, df = 1, p = 0.0016). Conclusions Individuals with HF performed worse on the TMT-A than HC. Age accounted for a significant proportion of the observed heterogeneity in the meta-regression. Future research should examine the relationship of age on cognition in individuals with HF.

The Difference

This meta-analysis tested whether autistic people show a marked, isolated difficulty with mentalising when assessed using the Frith -Happé Animations, an advanced test of mentalising (or ‘theory of mind’). Effect sizes were aggregated in multivariate meta-analysis from 33 papers reporting data for over 3000 autistic and non-autistic people. Relative to non-autistic individuals, autistic people underperformed, with a small effect size on the non-mentalising control conditions and a medium effect size on the mentalising condition. This indicates that studies have reliably found mentalising to be an area of challenge for autistic people, although the group differences were not large. It remains to be seen how important mentalising difficulties are in accounting for the social difficulties diagnostic of autism. As autistic people underperformed on the control conditions as well as the mentalising condition, it is likely that group differences on the test are partly due to domain-general information processing differences. Finally, there was evidence of publication bias, suggesting that true effects on the Frith -Happé Animations may be somewhat smaller than reported in the literature. Lay abstract Autistic people are thought to have difficulty with mentalising (our drive to track and understand the minds of other people). Mentalising is often measured by the Frith -Happé Animations task, where individuals need to interpret the interactions of abstract shapes. This review article collated results from over 3000 people to assess how autistic people performed on the task. Analysis showed that autistic people tended to underperform compared to non-autistic people on the task, although the scale of the difference was moderate rather than large. Also, autistic people showed some difficulty with the non-mentalising as well as mentalising aspects of the task. These results raise questions about the scale and specificity of mentalising difficulties in autism. It also remains unclear how well mentalising difficulties account for the social challenges diagnostic of autism.

Although functional asymmetry is very common and normal in professional athletes, the better interlimb symmetry between dominant and nondominant sides (bilateral symmetry) could contribute to successful performance in basketball. The aim of this study was to evaluate the importance of bilateral symmetry of the one-leg jumping and agility performances in differentiating basketball players according to their (i) playing position (guards, forwards, and centers) and (ii) performance levels (first division vs. second division). The participants were 102 professional male basketball players, with all members of the teams competing in the two highest national divisions at the moment of testing (height: 194.92 ± 8.09 cm; body mass: 89.33 ± 10.91 kg; 21.58 ± 3.92 years of age). Performance levels (first division, N = 58 vs. second division, N = 44) and playing positions (guards, N = 48; forwards, N = 22; centers, N = 32) were observed as dependent variables. We measured one-leg jumping capacities (running vertical jump and lay-up vertical jump), basketball-specific preplanned agility (CODS), and basketball-specific reactive agility (RAG), all executed on dominant and nondominant sides. Accordingly, the bilateral symmetry of jumping and agility was calculated by calculating the ratio of the corresponding performances on the dominant and nondominant sides. Factorial analysis of variance (performance levels × positions) indicated that the bilateral symmetry of one-leg jumping differentiated players according to their playing position, with better bilateral symmetry among guards (F-test = 6.11 (medium effect size) and 5.81 (small effect size), p < 0.05 for lay-up and running-jump symmetry, respectively). Performance levels significantly differed in the bilateral symmetry of lay-up jump, with better symmetry for first-division players (F-test = 10.11 (medium effect size), p < 0.001), which was mostly influenced by significant differences among guards. Playing positions and performance levels did not differ in bilateral symmetry of the CODS and RAG. The study reveals the importance of bilateral symmetry of the sport-specific performance in differentiating playing positions and performance levels in basketball. Further studies in other multidirectional sports and other sport-specific performances are warranted.

Objective. To confirm that physical activity program improves the symptoms of dementia and the most effective physical activity was selected to help establish exercise programs.Methods. Three databases, PubMed, Science Direct, and Willey online, were used to collect articles. The databases were published between January 2005 and December 2015. Keywords such as “dementia,” and “physical activity” were used in searching for papers. As a result, nine studies were selected in the second screening of the meta-analyses.Results. The improvement in the dementia symptom of physical capacity was 1.05 (high effect size, 95% CI: 0.03 to 0.73), ability of activity of daily living was 0.73 (slightly high effect size, 95% CI: 0.23 to 1.23), cognitive function was 0.46 (medium effect size, 95% CI: 0.26 to 0.66), and psychological state was 0.39 (lower than the medium effect size, 95% CI: 0.01 to 0.77).Conclusion. The physical activity for patients with dementia had an effect on the improvement of physical capacity and combined exercise was the most effective physical activity.

AbstractThe status signalling hypothesis aims to explain conspecific variation in ornamentation by suggesting that some ornaments signal dominance status. Here, we use multilevel meta-analytic models to challenge the textbook example of this hypothesis, the black bib of house sparrows (Passer domesticus). We conducted a systematic review, and obtained raw data from published and unpublished studies to test whether dominance rank is positively associated with bib size across studies. Contrary to previous studies, our meta-analysis did not support this prediction. Furthermore, we found several biases in the literature that further question the support available for the status signalling hypothesis. First, the overall effect size of unpublished studies was zero, compared to the medium effect size detected in published studies. Second, the effect sizes of published studies decreased over time, and recently published effects were, on average, no longer distinguishable from zero. We discuss several explanations including pleiotropic, population- and context-dependent effects. Our findings call for reconsidering this established textbook example in evolutionary and behavioural ecology, raise important concerns about the validity of the current scientific publishing culture, and should stimulate renewed interest in understanding within-species variation in ornamental traits.

BACKGROUND: Cyclergometry with functional electrical stimulation (FES-cycling) is a feasible method for rehabilitation. The concept is to promote exercise induced by depolarization of the motoneuron and muscular contraction. OBJECTIVE: To measure acute physiological responses to FES-cycling. METHODS: Retrospective study of data from ten healthy volunteers who performed FES-cycling, passive cycling and neuromuscular electrical stimulation (NMES) alone. Metabolic, ventilatory and cardiovascular parameters were analyzed. RESULTS: Oxygen uptake enhanced 97 ± 15% during FES-cycling, with medium effect size compared to NMES and large effect size compared to passive cycling. Energy expenditure enhanced 102 ± 15% during FES-cycling, with medium effect size compared to NMES and large effect size compared to passive cycling. Minute ventilation enhanced 115 ± 26% during FES-cycling, with small effect size compared to NMES and medium effect size compared to passive cycling. Cardiac output enhanced 21 ± 4% during FES-cycling, with medium effect size compared to NMES and passive cycling. Arterial – mixed venous oxygen content difference enhanced 60 ± 8% during FES-cycling, with a medium effect size compared to NMES and large effect size compared to passive cycling. CONCLUSIONS: FES-cycling enhances metabolic, ventilatory and cardiovascular demands and the physiological responses are higher than NMES and passive cycling.
