An age-related bias toward positive information in the older adult population has been identified by the literature and termed "the positivity effect." Many studies have been conducted to examine specific aspects of the positivity effect. However, those studies have introduced confounding variables, making the size of the actual positivity effect present in the overall older adult population difficult to estimate. Additionally, the methodology used by researchers has varied widely, raising the question of whether the effects observed by different studies are comparable. The goal of the present meta-analysis was to examine the overall effect size of the attentional positivity effect observed in the literature, as well as to examine the impact of methodological differences across studies on the effect sizes found. Thirty one studies were included in the meta-analysis. Meta-regression analyses were performed to examine the ability of stimulus type, attention bias measure, stimulus pairing, and effect type to explain variability in effect sizes across the sample. Results found a small aggregate effect size. Effect size variability was significantly explained by attention bias measure and effect type but not by stimulus type or stimulus pairing. Additionally, differences in the overall effect sizes of categories within each meta-regression variable were apparent, some of which were statistically significant.
