Abstract: Abstract Although a number of empirical studies have found support for distinct emotional information processing biases in young versus older adults, it remains unclear whether these biases are driven by differential processing of positive or negative emotional information (or both) and whether they are moderated by stimulus type, in particular face versus non-face, the former of which is known to be subject to distinct processing. To address these gaps in the literature, our analyses included 2237 younger (mean age = 21.61 years) and 2136 older (mean age = 70.58 years) adults from 73 data sets, 19 involving face stimuli and 54 involving non-face stimuli (objects or scenes). Our findings indicated a significant overall age-related positivity effect (Hedge’s g = 0.35) when comparing positive and negative stimuli, but consideration of emotionally neutral stimuli revealed significant age differences in emotional processing for negative stimuli only, with younger adults showing a stronger negativity bias. Furthermore, compared to emotionally neutral stimuli, both younger and older adults showed evidence of biases toward non-face positive and negative stimuli and toward positive but not negative face stimuli. Thus, although the present meta-analysis found evidence of an overall age-related positivity effect consistent with a shift toward positivity with aging, a different picture emerged when comparing emotional against neutral stimuli, and consideration of stimulus type revealed a distinct pattern for face stimuli, which may reflect the biological and social significance of facial expressions.
