Aging is associated with a decline in several neurocognitive processes but also with a preserved or even improved emotional functioning. As both neurocognitive and emotional processes are implicated in social cognition, what happens to this domain during aging? Social cognition broadly refers to the ability to construct mental representations of the relations between oneself and others and to use them to guide social behavior. It involves the processing of information that is relevant to guide the behavior in social contexts, but considering that most information is relevant for this purpose, social cognition became a term too general to be measurable. To make this construct quantifiable, it is typically divided into subdomains that are studied separately, among which emotional identification, theory of mind, and social perception are the most studied. In this comprehensive review, we discuss the core insights into the effects of aging on these domains of social cognition, present the main up-to-date findings and point to areas that demand further investigation. This review highlights that aging may affect all these domains, even if a preserved or even improved performance is occasionally found. Further studies are needed to reach higher consistency.
Public Significance StatementAging has been associated with decreasing biological and cognitive functioning, but also with increasing emotional regulation. Considering the role of emotional and cognitive abilities on social cognition, it is necessary to clarify the effects of aging on this domain, which is a fundamental component of successful social interactions. Social interactions are of extreme importance during aging considering that older adults with stronger social relationships are less likely to decline in cognitive functions.
