Fig 3. Average effect sizes of meta-analyses per modality.

The distributions of the original data included in the meta-analyses were often not reported. This is exemplified in S1 Table where we checked information on the data distributions of the 49 original papers included in a review of emotion recognition [20]. However, in the majority of papers, parametric statistics were employed, which may be taken as indicating normal distribution. EF, executive function; ET, eye-tracking; fMRI, functional MRI; MMN, mismatch negativity; PRS, polygenic risk score; ROI, region of interest; sMRI, structural MRI; SNP, single-nucleotide polymorphism; ToM, theory of mind.
