Exploring reliability heterogeneity with multiverse analyses: Data processing decisions unpredictably influence measurement reliability

Analytic flexibility is known to influence the results of statistical tests, e.g. effect sizes and p-values. Yet, the degree to which flexibility in data-processing decisions influences the reliability of our measures is unknown. In this paper I attempt …

Visualising two approaches to explore reliability-power relationships

The relationship between measurement reliability and statistical power is a complex one. Where reliability is defined by classical test theory as the proportion of ‘true’ variance to total variance (the sum of true score and error variance), power is …

Moving forward with questions of process and procedure in cognitive bias modification research: three points of consideration

There is ongoing debate surrounding the efficacy of Cognitive Bias Modification (CBM) for the reduction of emotional vulnerability. In part, the debate stems from researchers asking different questions of the existing research. Specifically, …
