AIM In order to study the role of imitation in relation to drinking, alcohol consumption among two peers was examined with experiments in a naturalistic drinking setting. METHOD In a bar lab, 135 young adults (52% women) were exposed to either a non-drinking, a light-drinking or a heavy-drinking same-sex model (i.e. a confederate) in a 30-min time-out(More)
Ample experimental research has found evidence for imitation of alcohol consumption in social encounters. However, these studies cannot reveal whether imitation is specifically related to alcohol and not to consumption in general. We investigated whether imitation is more evident when peers drink alcohol compared to other beverages. We observed sipping(More)
Research has demonstrated that when people are with heavy-drinking peers, they consume more alcohol than when they are in the company of light-drinking peers. This social influence process has usually been investigated in clinical laboratories or seminaturalistic drinking settings such as laboratory bars. The question remains whether these robust effects(More)
Research suggests that people adapt their own drinking behavior to that of other people. According to a genetic-differences approach, some individuals may be more inclined than others to adapt their alcohol consumption level to that of other people. Using a 3 (drinking condition) x 2 (genotype) experimental design (N = 113), we tested whether susceptibility(More)
BACKGROUND That alcohol consumption is strongly influenced by the drinking behavior of social company has been demonstrated in observational research. However, not everyone is equally vulnerable to other people's drinking, and it is important to unravel which factors underlie these individual differences. This study focuses on the role of psychosocial(More)
BACKGROUND Genital warts, which are caused by infection with human papillomavirus (HPV), are one of the most common sexually transmitted diseases in Europe. Although genital warts are commonly perceived as a non-serious condition, treatment is often long, of varying effectiveness and the recurrence rate is high. Very few studies have been performed on the(More)
AIM Being exposed to other people's drinking behavior has been demonstrated to influence individual's drinking levels. Imitation of alcohol consumption has mainly been investigated among same-sex drinking partners. This study examined whether imitation of alcohol consumption differs when people drink with same-sex or other-sex partners. METHOD To test the(More)
BACKGROUND A depressed Apgar score at 5 minutes is a marker for perinatal insults, including neurologic damage. We examined the association between 5-minute Apgar score and the risk of epilepsy hospitalization in childhood. METHODS Using records linked from population registries, we conducted a cohort study among singleton children born alive in the(More)
AIMS   Dual-process models imply that alcohol use is related to implicit as well as explicit cognitive processes. Few studies have tested whether both types of processes are related to ad libitum drinking. In a series of three studies, we tested whether both implicit and explicit alcohol-related cognitions predicted the amount of alcohol consumed in an ad(More)
INTRODUCTION Research demonstrates that cognitive biases toward drug-related stimuli are correlated with substance use. This study aimed to investigate differences in cognitive biases (i.e., approach bias, attentional bias, and memory associations) between smoking and non-smoking adolescents in the US and the Netherlands. Within the group of smokers, we(More)
