Judging emotional authenticity from dynamic facial expressions: a preregistered Bayesian analysis of individual differences - Motivation and Emotion

Accurately judging whether another person’s emotional display is genuine or deliberate is a core component of social interaction, yet prior research linking this ability to socio-cognitive traits has produced mixed and imprecise findings. Much of this inconsistency stems from small samples, static stimuli, and analytic approaches that overstate weak effects. In a high-precision preregistered study (N = 605), we examined how Theory of Mind, empathy, and alexithymia relate to emotional authenticit

A Meta-Analysis of the Impact and Heterogeneity of Explicit Demand Characteristics

Demand characteristics are a fundamental methodological concern in experimental psychology. Yet, little is known about the direction, magnitude, and consistency of their effects. We conducted a three-level meta-analysis of 253 effect sizes from 53 studies that manipulated explicit demand characteristics (EDCs). On average, EDCs led to small overall increases in hypothesis-consistent responding (g = 0.21, 95% CI [0.11, 0.30]). However, the effects were heterogeneous (between-study τ = 0.29; withi

Non-adjustment for multiple testing in multi-arm trials of distinct treatments: Rationale and justification

There is currently a lack of consensus and uncertainty about whether one should adjust for multiple testing in multi-arm trials of distinct treatments. A detailed rationale is presented to justify non-adjustment in this situation. We argue that ...
