The disagreement between people who named #theDress (the Internet phenomenon of 2015) "blue and black" versus "white and gold" is thought to be caused by individual differences in color constancy. It is hypothesized that observers infer different incident illuminations, relying on illumination "priors" to overcome the ambiguity of the image. Different experiences may drive the formation of diff...

We conducted this study to evaluate the prevalence of daytime sleepiness and evening chronotype, and to assess the extent to which both are associated with the use of caffeinated stimulants among 3,000 Thai college students. Demographic and behavioral characteristics were collected using a self-administered questionnaire. The Epworth Sleepiness Scale and the Horne and Ostberg Morningness-Evenin...

Chronotype is an established concept designed to identify distinct phase relationships between the expression of circadian rhythms and external synchronizers in humans. Although it has been widely accepted that chronotype is subjected to ontogenetic modulation, there is no consensus on the interaction between age and gender. This study aimed to determine the relationship between age- and gender...

Background. Chronotype is the attitude of a subject in determining individual circadian preference behavioral and biological rhythm associated with eating behaviors health.
 Objective. The aim this study was to evaluate associations between chronotype, adherence Mediterranean diet, attitudes healthy nutrition Turkish adults.
 Methods. A survey conducted online using platforms. total 1...

Abstract Chronotype refers to the time of day that people prefer be active or sleep and varies predictably across lifespan. In younger samples, morning-chronotype is related greater levels physical activity (PA) improved health outcomes. It unclear whether this pattern holds in older adults, a group commonly exhibits an “early bird” preference. We investigated differences PA patterns between ch...

Grundy and colleagues (1) conducted a study into how light influencesmelatonin in nurses during rotating shifts. Inter alia, it was concluded that the examined "two-12hour-days/two-12-hour-nights/5-days-off" pattern minimally disrupts melatonin production. Interestingly, chronotype information was obtained but appeared to have negligible effects on shift-work–melatonin relationships. The author...

background and objective : morningness–eveningness (me) refers to the individual differences in diurnal inclination, sleep-wake pattern for activity, and vigilance in the morning and evening. quantitative and qualitative components of sleep can be measured through its quality. this study aimed to evaluate the association of me chronotype with sleep quality and insomnia in students. materials an...

Bibliometric indices are a widely used measure of research impact. The aim of the current study was to identify and characterise the top one hundred most-cited research articles in the topic of chronotype research. A search of the Thomson Reuters Web of Science database returned 974 eligible articles ( published between 1990 and 2016). Citations for the 100 most-cited articles ranged between 43...

INTRODUCTION To investigate the relationship between common psychiatric disorders (CPDs) and sleep characteristics (evening chronotype, poor sleep quality and daytime sleepiness) among Thai college students. METHODS A cross-sectional study was conducted among 2,970 undergraduate students in Thailand. Students were asked to complete a self-administered questionnaire that collected information ...

In humans, a person's chronotype depends on environmental cues and on individual characteristics, with late chronotypes prevailing in youth. Social jetlag (SJL), the misalignment between an individual׳s biological clock and social time, is higher in late chronotypes. Strong SJL is expected in Uruguayan university students with morning class schedules and very late entertainment activities. Slee...
