Abstract The effects of sleep deprivation on cognitive performance and psychological variables related to were studied in 44 college students. Participants completed the Watson-Glaser Critical Thinking Appraisal after either 24 hours or approximately 8 sleep. After completing task, participants 2 questionnaires, one assessing self-reported effort, concentration, estimated performance, other off-task cognitions. As expected, sleep-deprived performed significantly worse than nondeprived task....

Evolutionary psychologists argue that human nature contains many discrete psychological adaptations. Each adaptation is theorized to have been functional in humans' ancestral past, and empirical evidence an attribute can come from showing it possesses complexity, efficiency, universality, other features of special design. In this article, we present a tutorial review the evidentiary forms evolutionary commonly use document existence We also heuristic framework for integrating evaluating...

Abstract The stability of subjective measures sleep, health, and well-being, as well the relationships between sleep health well-being were assessed over 3 months. Healthy college students with no consistent complaints completed a 7-day log battery surveys related to at separate times during Measures more strongly quality than quantity sleep. Further analyses using repeated results found that participants reported improved better but affect balance, life satisfaction, mood states unchanged...

The integration of self-driving vehicles may expose individuals with health concerns to undue amounts stress. Psychophysiological indicators stress were used determine changes in tonic and phasic levels brought about by a high-fidelity autonomous vehicle simulation. Twenty-eight participants completed one manual driving task two automated tasks. Participants reported their subjective level trust the systems using Automation Trust Survey. was indexed skin conductance trapezius muscle tension....

ABSTRACT Nightshift workers experience circadian misalignment thus negatively impacting many physiological systems which can change subjective states such as affect. The current study examined in affect and affective state across a simulated first nightshift. Ninety sleep‐deprived college students (33% female) completed series of surveys tasks four testing sessions during the night. participants Positive Negative Affect Schedule at beginning each session. Using these scores, we derived types...

To improve the healthcare environment where nurses work and patients receive care, it is necessary to understand elements that define environment. Primary include (a) occupants of room what knowledge, skills, abilities they bring situation; (b) tasks will be doing in room; (c) characteristics built better these components, a task analysis from human factor research was conducted study as cared for hospitalized patients. Multiple methods, including review nursing textbooks, observations,...

The purpose of the current study is to compare effects light physical activity sedentary behavior on cognitive task performance and meta-cognitive responses. Thirty-eight undergraduate students participated in study. participants used a stationary bicycle with desk top traditional while completing two complex tasks measures affect, motivation, morale, engagement. pedaled at slow pace (similar exertion normal walking pace) working. results indicated that did not change between workstations....

Background: Experiential education in higher provides opportunities for college student development that contribute to success. As such, a leisure program is posited as complement experiential programming. Purpose: This study explored the impact of (leisure skills) on dimensions success, including school satisfaction, life belonging, and self-esteem. Methodology/Approach: compared 531 skills students with group 136 not enrolled class. Findings/Conclusions: The results repeated-measures...

Abstract The current study examined the frequency with which shorter than 24-h work/rest cycles occur in locomotive engineer work schedules, and what effects these had on sleep quantity quality. results indicated that occurred 33.6% of days reported by 198 engineers. In addition, more frequently schedules created an on-call system, such as road pool turn extra board assignments, used predictable or regular times, assignments yard/local work. As would be expected, when engineers worked...

Many healthy adults report daytime napping. Surprisingly few studies, however, have examined spontaneous napping behavior, especially very short naps, in adults. The authors the prevalence of power naps (lasting less than 20 minutes) and longer (20 minutes or more) their effects on nighttime sleep a group young middle-aged reported similar patterns, with approximately 74% participants both groups reporting they had napped during 7-day sleep-log period. Almost half that average nap lasted...

In today's society, numerous situations arise in which sleep deprivation is a common occurrence. Subjective perceptions are vital component to understanding the effects of sustained performance during deprivation, as they may be first indication or on individual. Using theoretical framework Controlled Attention Model, this study examined 16 h under 28 acute perceived effort, motivation, and stress 24 participants while completing complex cognitive simple vigilance task. Perceived effort...
