Alcohol as social lubricant.

This study examines how consuming alcohol differentially affects the communicative behavior and perceptions of high and low social self‐esteem (SSE) women as they engage in a brief interaction with a flirtatious male. Alcohol myopia theory proposes that alcohol affects behavior when it blocks a person's normal inhibitions about enacting a behavior. It was predicted that low SSE women would be more inhibited when talking to a flirtatious male than would high SSE women and, therefore administration of a social self‐esteem measure and random assignment to an alcoholic or nonalcoholic beverage condition, participants (N=50) talked with an attractive, flirtatious male confederate. Low SSE women were less anxious and self‐disclosed more when drinking than when sober, whereas high SSE women were not significantly affected by alcohol consumption. The discussion highlights the complex and often contradictory effects of alcohol consumption on social interaction.     

The effects of violent video games on aggression.

Violent content video games such as Mortal Kombat and Doom have become very popular among children and adolescents, causing great concern for parents, teachers, and policy makers. This study cumulates findings across existing empirical research on the effects of violent video games to estimate overall effect size and discern important trends and moderating variables. Results suggest there is a smaller effect of violent video games on aggression than has been found with television violence on aggression. This effect is positively associated with type of game violence and negatively related to time spent playing the games. Directions for future programmatic research on video games are outlined.     

Protein synthesis-dependent long-term memory induced by one single associative training trial in the parasitic wasp Lariophagus distinguendus

Protein synthesis-dependent long-term memory in Apis mellifera and Drosophila melanogaster is formed after multiple trainings that are spaced in time. The parasitic wasp Lariophagus distinguendus remarkably differs from these species. It significantly responds to the artificial odor furfurylheptanoate (FFH) in olfactometer experiments, when this odor was presented during one single training trial, consisting of one sequence of host recognition behavior on a wheat grain infested by its hosts. Feeding wasps with actinomycin D erases the learned response 24 h after the training, demonstrating that protein synthesis-dependent long-term memory has been formed in L. distinguendus already after one single training.     

Energizing respites from work: a randomized controlled study on respite interventions

Increasing and new work demands drain employees’ energy resources at work. This 4-week longitudinal field experiment investigated the energizing potential of a respite intervention conducted at the workplace (either a simulated savouring nature intervention or a progressive muscle relaxation intervention). First, growth modelling analyses confirmed a linear trend for the growth of vigour and decline in fatigue across the days of the intervention group, indicating a typical upward resource trajectory. No changes appeared in the control group. Mediation analyses indicated that repeatedly engaging in a daily respite intervention influenced more stable energy levels after the intervention period indirectly through the immediate changes in daily energy levels during the intervention period. Findings suggest that, in some cases, respite interventions may present a useful tool to replenish and build energy resources at work. Implications for using respite intervention in organizational research and practice are discussed.     

Not Motivated to Act During Goal Pursuit: Powerlessness Blocks Motivation Transfer in Goal Systems

The current research investigates a motivational mechanism that contributes to the inferior goal striving and attainment of powerless individuals: the transfer of motivation from goals to means. We expected that this mechanism would work effectively only in powerful individuals. The results of an experiment and a field study confirmed our assumptions. The more motivated powerful people were to attain the goals, the more they engaged in self-determined action and, in turn, the more positively they experienced goal-related activities. No such relation was found for their powerless counterparts. Implications for power research and goal systems theory are discussed.
