    "subtitle": null,
    "abstract": "This study examined age effects on real-life language use and\nwithin-person variations in language use across social contexts.\nWe used the Electronically Activated Recorder (i.e., a portable\naudio recorder that periodically records sound snippets) to\ncollect over 31,300 snippets (30 seconds long) from 61 young\nand 48 healthy older adults in Switzerland across four days. We\nexamined vocabulary richness and grammatical complexity\nacross the social contexts of (a) activities (i.e., socializing,\nworking); and (b) conversation types (i.e., small talk,\nsubstantive conversation). Multilevel models showed that\nvocabulary richness and grammatical complexity increased\nduring socializing and substantive conversations, but decreased\nin small talk. Moreover, young adults produced shorter clauses\nat work than not at work. Furthermore, compared with young\nadults, older adults used richer vocabulary and more complex\ngrammatical structures at work; and used richer vocabulary in\nsmall talk. In contrast, young adults used richer vocabulary\nthan older adults during non-socializing and non-working\noccasions, such as watching TV and exercising. Results are\ndiscussed in the context of cognitive aging research with a\nnovel emphasis on context.",
