Oxytocin administration has demonstrated considerable promise for providing individualized support autistic people. However, studies evaluating the effects of oxytocin on characteristics have yielded inconsistent results. This systematic review and meta-analysis investigates effect social routinized behaviors in autism using recently developed methods to accurately assess potential impact size dependency publication bias. Our frequentist a significant summary estimate outcomes (d = 0.22, p < 0.001). The behavior was not statistically 0.14, 0.22), with follow up tests indicating that either equivalent (Z -1.06, 0.2), assuming smallest interest 0.25. Frequentist Bayesian assessments bias, as well results from Robust autism, indicated might be inflated due Future should aim reduce bias by preregistering analysis plans increase precision larger sample sizes.

To identify the optimal dose and type of physical activity to improve functional capacity reduce adverse events in acutely hospitalised older adults.Systematic review Bayesian model-based network meta-analysis.Four databases were searched from inception 20 June 2022.Randomised controlled trials that assessed effectiveness a activity-based intervention on at least one outcome people aged ≥50 years due an acute medical condition included. Pooled effect estimates (ie, standardised mean differences for ratio means events) calculated using random treatment effects meta-analysis models.Nineteen studies (3842 participants) met inclusion criteria. Approximately 100 Metabolic Equivalents Task per day (METs-min/day) (~40 min/day light effort or ~25 moderate activities) was minimal adults (standardised difference (SMD)=0.28, 95% credible interval (CrI) 0.01 0.55). The estimated 159 METs-min/day (~70 ~40 activities; SMD=0.41, CrI 0.08 0.72). Ambulation deemed most efficient intervention, reached 143 (~50 slow-paced walking; SMD=0.76, 0.35 1.16), showing high evidential power (87.68%). effective ambulation 74 (~25 SMD=0.25, 0.41). Physical interventions resulted decrease rate compared with usual care discharge (ratio means=0.96, 0.95 0.97; median time 7 days).This yielded low evidence supporting use in-hospital supervised programmes adults. As little as walking is sufficient minimise this population.PROSPERO CRD42021271999.

The prevalence of gaming disorder is assumed to be between 2%-5%. treatment effect different therapeutic interventions has not been studied extensively. This systematic review and meta-analysis sought identify all intervention studies on with a control group, determine the interventions, examine moderators. Studies applying using an appropriate comparison group were identified by searching electronic databases, previous reviews, reference lists. Data type treatment, name outcome measurement, symptom level other study characteristics extracted analyzed meta-regression. A total 38 76 sizes, originating from 9524 participants included. RoB2 ROBINS-I risk bias tools used assess within-study bias. Correlational hierarchical models robust variance estimation fitted size data yielded moderate summary estimate. Egger's sandwich test, funnel plot inspections, tests conducted studies. Results indicate that there may overall for disorder, but confidence in these findings compromised small-study effects, possible publication bias, limited pool, lack standardization. field needs more higher quality before evidence-base can support reliable meta-analytic estimates.

A Problem in Theory and More: Measuring the Moderating Role of Culture in Many Labs 2

Опубликована: Фев. 9, 2023

The multi-site replication study, Many Labs 2 (ML2), attempted to test whether population, site and setting variability moderates the likelihood of effect size. analysis concluded that sample location did not substantially affect replicability findings. In this paper, we raise several issues with ML2 approach adjudicating culture cast doubt on conclusion. These theoretical methodological problems (pre-registered at https://osf.io/6exr4) involve the: (1) selection studies sites for are theory-driven, (2) sampling mostly WEIRD people around world, (3) conflation participants’ cultural backgrounds country where samples came from, (4) use backronym by decomposing it into a scale, (5) application mean split variable. Moreover, simulations reveal strikingly low statistical power detecting influences in multi-side study designed like ML2. We propose methodologies address to( 5) re-analyzing dataset using an alternative approach. results suggest tackling only some design is insufficient overcome underlying deficiencies. conclude specific recommendations assessing role population future evidentiary value

Factors affecting the forced confabulation effect: a meta-analysis of laboratory studies

Memory, Год журнала: 2023, Номер 31(5), С. 635 - 651

Опубликована: Март 8, 2023

During police investigations, interviewees are sometimes forced to confabulate a response questions for which they don't know the answer. In this registered report, we conducted three-level meta-analysis examine whether forcing people an answer these can lead false memories confabulated details and/or events (i.e., confabulation effect). Results showed that indeed led production of memories. Qualitative reviews studies suggested effect is enhanced after receiving confirmatory feedback. Moreover, found evidence longer delays between phase and final memory task necessary observe entire events. However, caution needed when interpreting effect. Specifically, our moderator analyses revealed voluntarily produced more than confabulation. Also, exploratory analysis indicated was mainly observed in within-subject designs. Taken together, supports notion participants them later report such confabulations as part truth. Nonetheless, warranted because might be due introduction misinformation through asking unanswerable questions.

Methodological concerns underlying a lack of evidence for cultural heterogeneity in the replication of psychological effects

Communications Psychology, Год журнала: 2024, Номер 2(1)

Опубликована: Окт. 8, 2024

The multi-site replication study, Many Labs 2, concluded that sample location and setting did not substantially affect the replicability of findings. Here, we examine theoretical methodological considerations for a subset analyses, namely exploratory tests heterogeneity in studies between "WEIRD less-WEIRD cultures". We conducted review literature citing re-examination existing cultural variability, power stimulation detecting heterogeneity, re-analyses original tests. Findings indicate little variability low to detect effects 2 data, yet indicates study is cited regarding moderating role culture. Our reanalysis data found using different operationalizations culture slightly increased effect sizes but alter conclusions 2. Future can be improved with consideration which cultures are likely show variation as well priori planning appropriate sufficient effects.

Does the Mere Presence of a Smartphone Impact Cognitive Performance? A Meta-Analysis of the “Brain Drain Effect”

Media Psychology, Год журнала: 2023, Номер 27(5), С. 737 - 762

Опубликована: Ноя. 23, 2023

A growing body of research investigates the general possibility that mere presence a smartphone might negatively impact cognitive performance, with some researchers posing "brain drain" hypothesis which posits will impair working memory capacity and fluid intelligence, but not sustained attention response inhibition. To assess strength evidence for claim can this study reports systematic review six meta-analyses (k = 56, n 7093). Across functions, only single statistically significant pooled effect was found. Working impacted by smartphone, while results remaining functions produced null summary effects. The analysis also finds there is substantial methodological heterogeneity generally poor statistical power in domain. Overall, current meta-analysis provides limited support negative albeit smaller than theorized brain drain due to given concerns, extent literature or refute limited.
