Sabaoui, Ikram; Lotf, Said; Talbi, Mohammed – Education Sciences, 2021
In the face of the COVID-19 pandemic experienced around the world, new student lifestyles have had an impact on their daily behavior. The purpose of this study was to examine post-traumatic stress associated with the initial COVID-19 crisis in students (N = 280) with a mean age of 13 ± 1.70 and to determine the relationship between their reported…

Krishnan, Harini C.; Lyons, Lisa C. – Learning & Memory, 2015
Circadian clocks evolved under conditions of environmental variation, primarily alternating light dark cycles, to enable organisms to anticipate daily environmental events and coordinate metabolic, physiological, and behavioral activities. However, modern lifestyle and advances in technology have increased the percentage of individuals working in…

Valdez, Pablo; Ramírez, Candelaria; García, Aída – Mind, Brain, and Education, 2014
Circadian variations have been found in cognitive processes, such as attention, working memory, and executive functions, which may explain oscillations in the performance of many tasks. These cognitive processes improve during the day and decrease during the night and early hours of the morning. Sleep deprivation further decreases these cognitive…

Masismadi, Nur Adilah; Lee, Marcus J. C.; Che Muhamed, Ahmad Munir; Chia, Michael Y. H.; Aziz, Abdul Rashid – Clearing House: A Journal of Educational Strategies, Issues and Ideas, 2017
The literature indicates that glucose deprivation, dehydration, decreased sleep quality and quantity, and mood changes, independently and adversely can influence cognitive functions and therefore learning. The Ramadan fast is an annual religious act undertaken by Muslims where individuals refrain from consuming food and fluid during daylight…

Baker, Emma K.; Richdale, Amanda L.; Hazi, Agnes – Autism: The International Journal of Research and Practice, 2019
Both sleep problems and unemployment are common in adults with autism spectrum disorder; however, little research has explored this relationship in this population. This study aimed to explore factors that may be associated with the presence of an International Classification of Sleep Disorders--Third Edition defined sleep disorder in adults with…

Robertson, Laura; Jones, M. Gail – Science Scope, 2009
The study of biological clocks and circadian rhythms is an excellent way to address the inquiry strand in the National Science Education Standards (NSES) (NRC 1996). Students can study these everyday phenomena by designing experiments, gathering and analyzing data, and generating new experiments. As students explore biological clocks and circadian…

Hahn, Constanze; Cowell, Jason M.; Wiprzycka, Ursula J.; Goldstein, David; Ralph, Martin; Hasher, Lynn; Zelazo, Philip David – Developmental Science, 2012
To explore the influence of circadian rhythms on executive function during early adolescence, we administered a battery of executive function measures (including a Go-Nogo task, the Iowa Gambling Task, a Self-ordered Pointing task, and an Intra/Extradimensional Shift task) to Morning-preference and Evening-preference participants (N = 80) between…

Anacleto, Tâmile Stella; Adamowicz, Taísa; Simões da Costa Pinto, Laura; Louzada, Fernando Mazzilli – Mind, Brain, and Education, 2014
Although the environmental light/dark cycle is the main zeitgeber for the human species, the social cues seem to be important in the synchronization of circadian rhythms. In Brazil, the existence of two school schedules--one with only morning classes (MG) and other with only afternoon classes (AG)--allows the investigation of the effect of school…

Gaultney, Jane F. – Journal of Postsecondary Education and Disability, 2014
The pediatric literature indicates that children with ADHD are at greater risk for sleep problems, daytime sleepiness, and some sleep disorders than children with no diagnosed disability. It has not been determined whether this pattern holds true among emerging adults, and whether comorbid sleep disorders with ADHD predict GPA. The present study…

Gritton, Howard J.; Kantorowski, Ana; Sarter, Martin; Lee, Theresa M. – Learning & Memory, 2012
Circadian rhythms influence a variety of physiological and behavioral processes; however, little is known about how circadian rhythms interact with the organisms' ability to acquire and retain information about their environment. These experiments tested whether rats trained outside their endogenous active period demonstrate the same rate of…

Friborg, Oddgeir; Sundby, Jørgen; Rognmo, Kamilla; Rosenvinge, Jan H.; Bergvik, Svein – Applied Cognitive Psychology, 2018
Seasonal changes in daylight are substantial in subarctic areas and are known to affect circadian sleep rhythms. We examined whether seasonality in cognitive performance also exists and to what extent seasonality in sleep moderates this relationship. In the city of Tromsø (Norway) at 69°N, 182 adolescents (36% male; mean age 16.8 years)…

Sakai, Takaomi; Inami, Show; Sato, Shoma; Kitamoto, Toshihiro – Learning & Memory, 2012
In addition to its established function in the regulation of circadian rhythms, the "Drosophila" gene "period" ("per") also plays an important role in processing long-term memory (LTM). Here, we used courtship conditioning as a learning paradigm and revealed that (1) overexpression and knocking down of "per" in subsets of brain neurons enhance and…

Debarnot, Ursula; Sahraoui, Djafar; Champely, Stephane; Collet, Christian; Guillot, Aymeric – Research Quarterly for Exercise and Sport, 2012
In this study, we examined the effect of circadian modulation on motor imagery (MI) time while also considering the effects of task complexity and duration. The ability to imagine in real time was influenced by circadian modulation in a simple walking condition, with longer MI times in the morning and evening sessions. By contrast, there was no…

Remmelink, Esther; Smit, August B.; Verhage, Matthijs; Loos, Maarten – Learning & Memory, 2016
Many neurological and psychiatric disorders are characterized by deficits in cognitive flexibility. Modeling cognitive flexibility in mice enables the investigation of mechanisms underlying these deficits. The majority of currently available behavioral tests targeting this cognitive domain are reversal learning tasks that require scheduled food…

Hohn, Vanessa D.; de Veld, Danielle M. J.; Mataw, Kawita J. S.; van Someren, Eus J. W.; Begeer, Sander – Journal of Autism and Developmental Disorders, 2019
Insomnia is a common source of distress in adults with autism spectrum disorder (ASD). Two characteristics of ASD could be relevant to insomnia complaints by hampering the entrainment of a circadian sleep-wake rhythm. First, sensory hyper-reactivity could lead to bright light avoidance and thus affect photoperiodic input to the circadian system.…
