Older Adults’ Memory Lapses Linked to Problems Processing Everyday Events

Wide-Eyed Fear Expressions May Help Us – and Others – to Locate Threats
Wide-eyed expressions that typically signal fear may enlarge our visual field and mutually enhance others’ ability to locate threats, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The research, conducted by psychology graduate student Daniel Lee of the University of Toronto with advisor Adam Anderson, suggests that wide-eyed expressions of fear are functional in ways that directly benefit both the person who makes the expression and the person who observes it. The findings show that widened eyes provide a wider visual field, which can help us to locate potential threats in our environment.
