Editorial: Special Issue On Achievement, Chronotype And Circadian Patterns Of Cognition
 
Abstract
This special issue is about circadian rhythm by highlighting its effects on teaching, learning and cognitive performance. Studies related to circadian rhythm and its effects on academic performance arouse more interest in recent years. Therefore we aimed to publish a special issue about this topic. There are eight valuable articles in this special issue and a brief summary of each article is presented in this editorial. In sum the results of articles showed that not only the chronotype (morning, evening type), but also sleep hygiene, sleep quality, sleep problems are important for cognitive activities and these could change in different countries because of their latitude and longitude. Additionally, the studies highlighted here show the need for more detailed assessment of the influential factors of academic achievement in combination with short-time laboratory tests, as well as standardised tests in field settings.
