The present study examined dream habits, and their relation to sleep patterns, in 1151 preteens (597 boys; 554 girls; 11.31 ± 0.62 years old).

Sleep habits and their relation to self-reported attention and class climate in preteens.

Objectives/design: Sleep is fundamental in daily functioning, especially in teenagers who are in a critical period of their development. Accordingly, a deteriorated sleep, that is increasingly common in this age group, has been related to poorer school performance. The goal of this cross-sectional study was to collect up-to-date sleep data in preteens, and to examine their relation with two important dimensions for school achievement, which are self-reported attention and class climate at school.

The Impact of Priming on Speed Reduction on a Ski Slope.

We tested a field-adapted priming procedure (a technique used to subtly activate mental representations and guide behavior) on a ski slope, with the goal of reducing risk behavior in winter sports. At cableway stations, skiers were initially exposed eight times to a prevention poster displaying a logo and a "slow down" message. The "slow down" concept was activated on the ski slope by exposing skiers (or not) 10 times to the logo featured on the poster.

"I Wanna Be the Very Best!" Agreeableness and Perseverance Predict Sustained Playing to Pokémon Go: A Longitudinal Study.

Objective: The smartphone game Pokémon Go™ has attracted much scientific attention regarding its potential health-related outcomes. Most studies, however, limited their investigation to short-term outcomes. The aim of the present study is to investigate the role of personality traits in predicting sustained playing to the game on a 6-month period as well as related health outcomes in terms of distance walked per day.
