Abstract

This article presents a study investigating the relationships between caffeine consumption, cognitive slips-failures, sleep and a short multidimensional self-report measure of daily stress state, the Short Stress State Questionnaire - Daily (SSSQ-D; Helton, Fields, & Thoreson, 2005). Thirteen participants filled out the SSSQ-D twice daily for approximately 14 days, once in the morning and once at night. They also reported daily cognitive slips-failures, caffeine consumption, and their sleep was recorded using actigraphs. Daily Distress and Worry correlated significantly with cognitive slips and sleep duration between-subjects. Until more is known, human operators should get the recommended 7-8hrs of sleep.
