Sleep contributions to gist extraction

Context

At every moment, we are exposed to a massive amount of information from the outside world. This information is scanned for patterns to allow for the extraction of gist, or essential meaning. Gist extraction can be thought of as the process of finding commonalities across items, extracting rules, and abstracting themes. Although these processes are present during wake, sleep has been shown to facilitate gist extraction over and above the effects of wake. Furthermore, individual differences in sleep physiology has been shown to be associated with individual differences in gist extraction. In this project, I identified multiple conceptualizations of gist (inferential gist, sequence gist, single-item gist) and measured them in the same people at three time points: the evening before sleep, the morning after sleep, and seven days later.
