Abstract： The effects of light on social cognition and social behavior as a specific form of non-image forming (NIF) function are less investigated than any other NIF functions, which is a promising field. Natural light and artificial light exert different influences on prosocial and antisocial behaviors. At present, the underlying psychological mechanisms mainly focus on mood, self construal, sense of anonymity, moral salience and embodied cognition. Future studies should put emphasis on dynamic lighting, laboratory studies of natural light, replications of previous studies and investigations of possible psychological and neuro-endocrine mechanism.

Abstract： Besides affecting vision, light exerts powerful non-visual effects on a wide range of biological functions and behaviors, such as modulating circadian rhythm, melatonin suppression, and acute alertness. Comprehensive studies on the effect of light on human circadian rhythm now lead more researchers to pay attention to the effects of light on acute alertness. Here, we summarized (1) different measures of alertness, (2) factors that may influence the effect of light on alertness like illuminance, exposure, timing, wavelength and color temperature, (3) promising applications of the alerting effect of light in some affective disorders, circadian rhythm, and office lighting, and (4) future directions focusing on investigation of neural mechanisms, optimal lighting characteristics, and potential confounds.

Abstract： Sleep problems are more common with the prevalence of digital media devices. Subjective and objective research has shown evidence of negative sleep impacts of digital media usages. The underlying mechanisms involve sleep displacement, hyperarousal and effects of screen light and electromagnetic radiation. Sleep education, restriction of digital media usage and blocking blue light from screen can be promising options to alleviate the undesirable effects of digital media on sleep. More effort should be devoted to the integration of theoretical models, causality establishment between digital media and sleep, objectivization and standardization of measurements, refined classification of digital media user behaviors and local research.
