Sleep problems and stress are common among students and are associated with negative effects on academic performance as well as mental and physical health risks, but studies exploring mediating factors between stress and sleep on a daily basis are scarce. This study aimed to investigate the relationship of daily stress, Bedtime procrastination (BP) (i.e.

Measuring Achievement, Affiliation, and Power Motives in Mobility Situations: Development of the Multi-Motive Grid Mobility.

The current study introduces the Multi-Motive Grid Mobility (MMG-M) in an age-stratified sample ( = 206) that aims to disentangle six motive components - hope of success, hope of affiliation, hope of power, fear of failure, fear of rejection, and fear of power - in mobility-related and mobility-unrelated scenarios. Similar to the classical Multi-Motive Grid (MMG), we selected 14 picture scenarios representing seven mobility and seven non-mobility situations. The scenarios were combined with 12 statements from the MMG.

On the difficulty to think in ratios: a methodological bias in Stevens' magnitude estimation procedure.

In the field of new psychophysics, the magnitude estimation procedure is one of the most frequently used methods. It requires participants to assess the intensity of a stimulus in relation to a reference. In three studies, we examined whether difficulties of thinking in ratios influence participants' intensity perceptions.

Pretty crowds are happy crowds: the influence of attractiveness on mood perception.

Empirical findings predominantly support a happiness superiority effect in visual search and emotion categorization paradigms and reveal that social cues, like sex and race, moderate this advantage. A more recent study showed that the facial attribute attractiveness also influences the accuracy and speed of emotion perception. In the current study, we investigated whether the influence of attractiveness on emotion perception translates into a more general evaluation of moods when more than one emotional target is presented.

Valuing humans over animals - Gender differences in meat-eating behavior and the role of the Dark Triad.

Empirical findings demonstrate gender differences in attitudes toward meat consumption and actual meat-eating behavior. Furthermore, several studies have found that men score higher on all three Dark Triad personality dimensions (Machiavellianism, narcissism, and psychopathy). In this study, we investigated whether these personality differences mediate the association between gender and meat-eating justification, which in turn was expected to predict meat consumption.
