Beyond larks and owls: Revisiting the circadian typology using the MESSi scale and a cluster-based approach.

Chronopsychological research typically applied the morningness-eveningness dimension, resulting in a distinction between morning, intermediate, and evening chronotypes. However, in recent years, new measures have been developed that transcend the traditional "morning larks" vs. "night owls" dichotomy and better capture the complexity of individual differences in circadian rhythmicity.

Exploring the nexus between sleep, chronotype, and non-cognitive predictors in university students: Implications for academic success.

While the association between sleep-related variables and academic achievement is widely acknowledged, limited attention has been directed towards exploring non-cognitive predictors of academic achievement such as conscientiousness and self-regulation. In this study, we investigated the relationships between various sleep-related factors (circadian preference, chronotype, sleep duration, quality, and irregularity) and non-cognitive predictors (conscientiousness, self-regulation, self-efficacy, and achievement motivation) in 637 university students. Bivariate analyses revealed moderate to strong correlations among several sleep-related measures.

Gender and circadian preferences influence emotions and motivation in secondary mathematics classrooms.

Many studies have reported poor school achievement in evening persons and general circadian fluctuations in cognition. The aim of this study was to analyze circadian fluctuations in a cross-sectional design and examine the effects of chronotype on situational emotions and intrinsic motivation. A cross-sectional survey study was conducted in three Turkish secondary schools with a total sample of 599 students (283 females and 316 males).

Development and psychometric validation of a brief scale to measure environmental perception based on the 2-major environmental values model in adolescents and adults.

Background: The worldwide ecological crisis, including global climate change, is leading to increased awareness and attitudes towards environmental problems. To address these problems, studies of human attitudes are needed. This study is based on the 2-Major Environmental Values (2-MEV) model, which measures two components of environmental attitudes: Preservation and Utilization.

Big five personality and recreation specialization are related to satisfaction with life in birders.

Personality traits and recreation specialization are related to an individual's satisfaction with life. In addition, previous research has identified relationships between personality traits and recreational specialization. However, little is known about the interrelationship of the two variables in relation to life satisfaction.
