Affect Across the Wake-Sleep Cycle

Abstract Affective scientists traditionally have focused on periods of active wakefulness when people are responding to external stimuli or engaging in specific tasks. However, we live much our lives immersed experiences not related the current environment tasks at hand—mind-wandering (or daydreaming) during and dreaming sleep. Despite being disconnected from immediate environment, brains still generate affect such periods. Yet, research stimulus-independent has remained largely separate affective science. Here, suggest that one key future direction for science will be expand field view by integrating wealth findings mind-wandering, sleep, provide a more comprehensive account across wake-sleep cycle. In developing argument, address two issues: variation cycle, benefits expanding study full considering these issues, highlight methodological clinical implications
