Further resources on the interpretation of null results.

A dataset was generated showing simulated data points in two groups A and B. Group A follows a normal
distribution with a mean of 10 and a standard deviation of 1, while Group B exhibits a bimodal distribution, characterized by
peaks at 9 and 11 with a standard deviation of 0.5. As shown in the figure (A), barplots often fail to capture the true distribution
of the data. Although boxplots in (B) provide more insights into the data distribution compared to barplots, violin plots in (C)
and raincloud plots in (D) provide a more accurate representation of the actual data distribution. Reproducible code to generate
this figure is available at https://osf.io/mk5qa/.

Papers are one-way conversations. Getting additional info from authors can be hard, so clear reporting from the outset is critical.

In our new preprint, we (@annalschubert.bsky.social, Meike Steinhilber & @heeminkang.bsky.social) propose a set of psych reporting guidelines osf.io/preprints/ps...

Any comments and feedback are very welcome! If you don't have access to the full-text article, either contact me via ResearchGate (www.researchgate.net/profile/Heem...) or find the preprint on OSF (doi.org/10.31219/osf...). (6/6)

You can use a point-and-click web application to generate the main forest plot, funnel plot, as well as a forest plot for each subgroup analysis (dsquintana.shinyapps.io/ot_meta_exec/). The R code to run the application on a local computer is also available on OSF (osf.io/7eg5u/). (5/6)

Interestingly, a subgroup analysis on the subcategories of executive functions showed a small effect on improving cognitive flexibility (g=0.20, P=0.02), which warrants further studies to investigate the effect of oxytocin administration on flexibility. (4/6)

Meta-analyzing 20 effect sizes from 13 studies, we did not find a significant effect of OT on overall executive functions (g=0.07, P=0.3). This result was corroborated by the Robust Bayesian meta-analysis BF=0.1, i.e. moderate support for the absence of an effect for the overall meta-analysis (3/6)

Recent studies have shown that oxytocin is potentially involved in a wider range of functions than previously thought, including learning and memory. To summarize the current literature, we meta-analyzed the effects of oxytocin administration on non-social executive functions. (2/6)
