Background. Here we report on a meta-analysis of the attentional blink (AB) research focussed on specific reading impairment, commonly referred to as developmental dyslexia. The AB effect relates to a limitation in the allocation of attention over time and examined in a dual-target rapid serial visual presentation paradigm. When the second target appears in close temporal proximity to the first target, the second target is reported less accurately. Method. A Web of Science search with terms 'dyslexia attentional blink' returned 13 AB experiments (11 papers) conducted with developmental dyslexia (9 were included in this meta-analysis). The main pattern of performance was lower overall accuracy in groups of individuals with dyslexia relative to typically reading peers. That is, a between-group main effect. This meta-analysis examined the size of the between-group effect in relation to physical presentation characteristics, which differed between and within experiments. Results. Four noteworthy variables were related to the between group effect-size; fixation duration (positive relationship, R2 = .89, p <.01, n = 6), maximum temporal position of T2 (negative relationship, R2 = .46, p <.05, n = 9), the difference between the minimum and maximum temporal position of T2 (negative relationship, R2 = .53, p <.05, n = 9), and the stimulus onset asynchrony (negative relationship, R2 = .46, p <.05, n = 9). Discussion. These are discussed with respect to the preparation of task-set, temporal orienting, and speed of processing, recommending these as considerations for future research.

The Relationship

The purpose of this meta-analysis study is to examine the correlations between the Dimensions of Learning Organization Questionnaire (DLOQ) and frequently examined outcomes including organizational performance and employee attitudes. Positive relationships were found between the DLOQ and organizational performance (e.g., financial, knowledge, and innovative performance) and employee attitudes (e.g., organizational commitment and job satisfaction) and the sub-dimensions (e.g., affective, continuance, and normative commitment), with a notable exception of a negative relationship between the DLOQ and turnover. Because the DLOQ has been used in many countries over the years, this study also examined the influence of national culture on the outcomes. Power distance moderated the relationship between the learning organization and overall organizational performance. Our meta-analytic review makes substantive contributions to the literature on the learning organization concept and the study of national culture as a significant moderator. Implications of these findings and suggestions for future research are discussed.

Explicit Measures

Psychological interest in stereotype measurement has spanned nearly a century, with researchers adopting implicit measures in the 1980s to complement explicit measures. One of the most frequently used implicit measures of stereotypes is the sequential priming paradigm. The current meta-analysis examines stereotype priming, focusing specifically on this paradigm. To contribute to ongoing discussions regarding methodological rigor in social psychology, one primary goal was to identify methodological moderators of the stereotype priming effect—whether priming is due to a relation between the prime and target stimuli, the prime and target response, participant task, stereotype dimension, stimulus onset asynchrony (SOA), and stimuli type. Data from 39 studies yielded 87 individual effect sizes from 5,497 participants. Analyses revealed that stereotype priming is significantly moderated by the presence of prime–response relations, participant task, stereotype dimension, target stimulus type, SOA, and prime repetition. These results carry both practical and theoretical implications for future research on stereotype priming.

Objective: To determine the difference in level of dental caries in adults and children who chew sugar-free gum (SFG), compared with those who do not chew SFG or use alternatives such as lozenges, candies, rinses, tablets, and other nonchewing controls. Methods: Systematic review of published literature. Results: Twelve studies of interventions of SFG for dental caries outcomes were included. SFGs were found to significantly reduce caries increment, giving a preventative fraction (PF) of 28% (95% CI, 7% to 48%). Including the 8 trials that used xylitol gum only as the basis of the intervention, the PF was 33% (95% CI, 4% to 61%). No adverse effects were recorded. There was a high level of heterogeneity among the trials included. Conclusion: The findings of this review provide tentative evidence that chewing SFG reduces caries increment in comparison to nonchewing controls. However, there is a considerable degree of variability in the effect and the trials included were generally of moderate quality. There is a need for future research to explore the acceptability and feasibility of the use of SFG as a public health intervention (PROSPERO 2018 CRD42018094676). Knowledge Transfer Statement: The results of this study can be used by clinicians when deciding how best to implement dental caries prevention regimes for their patients. With consideration of cost and patient preference, this information could help to develop national policy directives on caries prevention and dictate the direction of future clinical research.

Abstract Background Low back pain during pregnancy affects the normal daily activities of pregnant women to a certain extent. Current studies have shown that Kinesio Taping (KT) may be a treatment for low back pain during pregnancy, but there is still a lack of key evidence. The purpose of this study is to evaluate the efficacy and safety of KT in the treatment of low back pain during pregnancy. Methods PubMed, Web of Science, The Cochrane Library, Scopus, Embase, Wanfang Data, CNKI, and VIP databases were searched to collect randomized controlled trials (RCTs) of the efficacy of KT intervention on low back pain in women during pregnancy. The retrieval time limit is from the establishment of the database to April 2021. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias in the included studies. Meta-analysis was performed using RevMan5.3 software. Results A total of 7 RCTs were included, including 444 patients. Meta-analysis results showed that: Compared with the control group, KT intervention could significantly improve low back pain and dysfunction, VAS score (− 1.62, 95%CI − 2.08 to − 1.16, P < 0.00001, I2 = 77%), RMDQ score (− 1.00, 95%CI − 1.54 to − 0.46, P = 0.0003, I2 = 80%); The results of the meta-analysis of the subgroup showed that compared with the control group, the KT intervention was less than or equal to 1 week, and the waist pain and dysfunction were improved, with statistically significant differences. The difference in the improvement of low back pain was statistically significant after KT intervention for more than 1 week, but there was no statistically significant difference in RMDQ score (− 1.25, 95%CI − 2.66 to 0.15, P = 0.08, I2 =77%). Compared with the control group, KT intervention improved low back pain in the second and third trimesters, and the difference was statistically significant. Conclusion KT has a positive effect on the improvement of low back pain during pregnancy, KT intervention can significantly improve pregnant women’s low back pain and dysfunction problems, improve the quality of life. It is suggested that future research should focus on the prevention and treatment of low back pain during pregnancy to provide more research data for improving women’s health.

Does time management work? We conducted a meta-analysis to assess the impact of time management on performance and well-being. Results show that time management is moderately related to job performance, academic achievement, and wellbeing. Time management also shows a moderate, negative relationship with distress. Interestingly, individual differences and contextual factors have a much weaker association with time management, with the notable exception of conscientiousness. The extremely weak correlation with gender was unexpected: women seem to manage time better than men, but the difference is very slight. Further, we found that the link between time management and job performance seems to increase over the years: time management is more likely to get people a positive performance review at work today than in the early 1990s. The link between time management and gender, too, seems to intensify: women’s time management scores have been on the rise for the past few decades. We also note that time management seems to enhance wellbeing—in particular, life satisfaction—to a greater extent than it does performance. This challenges the common perception that time management first and foremost enhances work performance, and that wellbeing is simply a byproduct.
