Disgust and the rubber hand illusion: a registered replication report of Jalal, Krishnakumar, and Ramachandran (2015)

2018
PMCID: 5954052
PMID: 29780877
DOI: 10.1186/s41235-018-0101-z

[…] h subsequent replications, a phenomenon termed the “Winner’s Curse” (Button et al., ). Therefore, we applied a required power level of 0.95 and 30% of the effect size, with Cohen’s dz. = 0.594. Using G*Power 3.1 power analysis software (Faul, Erdfelder, Buchner, & Lang, ), we computed the required sample size for the disgustingness condition as a function of effect size dz. = 0.594, the required s […]

[…] re they hospitalized or given the sGC therapy. To assure that our sample size has sufficient power to detect the group and group × condition interaction effects, we conducted power calculations using G*Power (Version 3.1.9.2) based on effect sizes estimated from the prior developmental study, which showed medium effect sizes for the effects of prenatal sGC exposure on stress reactivity and the ass […]

Diffusion markers of dendritic density and arborization in gray matter predict differences in intelligence

2018
Nat Commun
PMCID: 5954098
PMID: 29765024

[…] was not possible to estimate the necessary sample size a priori based on existing literature. Instead, we collected data from a reasonably large sample and computed the achieved power post hoc using G*Power. The analysis was based on the multiple regression model reported for sample S259 (Table ) (f2 = 0.16, α = 0.05, 10 predictors, 259 participants) and yielded a power of 0.99, thereby indicatin […]

[…] obese) who attend PC spontaneously and of their own accord, especially in the Santo Amaro (São Paulo), and who meet the inclusion criteria for the study. Power analysis was calculated a priori using G*Power 3.1 [] for repeated-measures analysis of variance (ANOVA). The results indicated that a sample size of 240 (n = 80 per group) is needed, with a significance level of 5% and a power of 80% to d […]

[…] e and other variables such as profession, religion, marital status and age group. The level of significance was set at P < 0.05.A post hoc analysis of the power of the study was carried out using the G*power 3.1.9.8 software. At a medium effect size of 0.5, it was found to be 86 and 91% for 12 months and lifetime violence respectively, when compared with those who did not report violence. […]
