Sleep and Impressions Formed (05-02-22)

Researchers have determined how sleep deprivation influences impressions formed of faces; it is likely that their findings can be extended to other contexts.  Investigators lead by van Egmond report (in a study published in Nature and Science of Sleep) that “young adults when sleep-deprived evaluate angry faces as less trustworthy and healthy-looking. Furthermore, neutral and fearful faces appear less attractive following sleep loss. . . . The participants spent one night with no sleep at all and one night with an eight-hour sleep opportunity. [Data were collected] in the mornings following both nights.”
