Minor traumatic injuries in the emergency department pre- and post-implementation of an emergency care access point.

Objective: In the Netherlands, out-of-hours General Practice Cooperatives (GPCs) increasingly collaborate with Emergency Departments (EDs) to form an Emergency Care Access Point (ECAP). ECAPs aim to decrease the number of low-urgent ED attendances, of which many compromise minor traumatic injuries. In this study, we evaluated the impact of ECAP implementation on the incidence of minor traumatic injuries in the ED.

The influence of culture and close others on the effectiveness of (self)-persuasion.

Although self-persuasion was shown to be more effective than direct persuasion in changing attitudes and intentions, its effectiveness in different cultures remains unclear. Furthermore, research suggests that Eastern individuals tend to incorporate close others in the self to a larger extent than Western individuals. Combining both lines of research, the current studies examined whether thinking of a close other would influence the effectiveness of (self)-persuasion across cultures.

Self-Persuasion Increases Healthy Eating Intention Depending on Cultural Background.

Unhealthy eating behavior has become a global health risk and thus needs to be influenced. Previous research has found that self-persuasion is more effective than direct persuasion in changing attitudes and behavioral intentions, but the influence of the cultural backgrounds of those being persuaded remains unclear. We conducted two studies to investigate the effectiveness of self-persuasion and direct persuasion techniques in promoting healthy eating intention among different ethnicities in the Netherlands.

Time for Action: Verbal Action Cues Influence Temporal Binding.

Prior research has shown that our perception of time is compressed when we volitionally perform actions, a phenomenon referred to as temporal binding. In three studies, we investigated the degree to which contextual cues that signaled other agents and related to actions would influence binding, given that those cues may affect individual's feelings of independent action performance. Participants heard action verbalizations that did or did not match actions that participants had already begun performing.

Quick question or intensive inquiry: The role of message elaboration in the effectiveness of self-persuasive anti-alcohol posters.

Self-persuasion (i.e., generating your own arguments) is often more persuasive than direct persuasion (i.

Self-Persuasion on Facebook Increases Alcohol Risk Perception.

In this experiment, we examined if participating in a Facebook group by generating antialcohol arguments (self-persuasion) is more effective than reading antialcohol posts of others (direct persuasion) in changing alcohol consumption, risk perception, and attitudes. In addition, it was examined if submitting posts moderated these effects. Participants logged into their Facebook account and joined a group that contained posts with antialcohol arguments.

Self-persuasion in media messages: Reducing alcohol consumption among students with open-ended questions.

Self-persuasion (self-generation of arguments) is often a more effective influence technique than direct persuasion (providing arguments). However, the application of this technique in health media communications has received limited attention. In two experiments, it was examined whether self-persuasion can be successfully applied to antialcohol media communications by framing the message as an open-ended question.

Re-Examining the Agentic Shift: The Sense of Agency Influences the Effectiveness of (Self)Persuasion.

In the present study we investigated whether differences in the sense of agency influenced the effectiveness of both direct persuasion and self-persuasion techniques. By manipulating both the delay and contingency of the outcomes of actions, participants were led to experience either a low or high sense of agency. Participants were subsequently presented with arguments as to why a clean local environment is important (direct persuasion), or were asked to generate those arguments themselves (self-persuasion).

Put your plan into action: The influence of action plans on agency and responsibility.

While action plans and intentions have been considered to be important factors contributing to the personal sense of causation known as agency, the present research is the first to empirically investigate how action plans influence agency. Participants in multiple studies were required to plan or not to plan ahead their actions. Results consistently show that on trials in which participants were required to plan their actions, participants experienced reduced agency compared to trials in which participants were not required to plan their actions.

Increasing first-time blood donation of newly registered donors using implementation intentions and explicit commitment techniques.

Background And Objectives: Most blood donors stop donating blood at the beginning of their donor career. This intervention study aims to increase first-time return behaviour of newly registered donors using implementation intentions and explicit commitment techniques.

Materials And Methods: Newly registered donors (N = 937) received an extra information sheet during their medical check-up wherein implementation intentions and explicit commitment techniques were tested.

Smoking-related warning messages formulated as questions positively influence short-term smoking behaviour.

Research demonstrated that by reformulating smoking warnings into questions, defensive responses in smokers are reduced and smoking-related risk perception increases. We explored whether these positive outcomes can be generalised to actual behaviour. Participants saw either a movie presenting subheadings with smoking-related questions or statements.

Authority defied: need for cognitive closure influences regulatory control when resisting authority.

The present studies examined whether differences in need for cognitive closure (NCC) were related to differences in regulatory control when confronted with authority. In two studies, levels of regulatory control were measured when participants resisted (Study 1; N = 46) or prepared to resist the influence attempt of an authority figure (Study 2; N = 50). Results showed that resisting the influence attempt from a high-authority figure was more depleting for participants higher in NCC compared to individuals lower in NCC.

Return behavior of occasional and multigallon blood donors: the role of theory of planned behavior, self-identity, and organizational variables.

Background: For blood establishments it is important that blood donors return for a donation. Past research has stressed the importance of theory of planned behavior (TPB) on return behavior, but self-identity (SI) and organizational variables (OVs) might play a role as well. This study added SI and OVs to the TPB to identify the determinants for return behavior.

Empathy is a beautiful thing: empathy predicts imitation only for attractive others.

Research shows that we spontaneously imitate people. Moreover, empathy predicts the degree of this non-conscious imitation. Little is known, however, if or how this expression of empathy is influenced by stable physical characteristics of our interaction-partners.

Assessment of implicit sexual associations in non-incarcerated pedophiles.

Offences committed by pedophiles are crimes that evoke serious public concern and outrage. Although recent research using implicit measures has shown promise in detecting deviant sexual associations, the discriminatory and predictive quality of implicit tasks has not yet surpassed traditional assessment methods such as questionnaires and phallometry. The current research extended previous findings by examining whether a combination of two implicit tasks, the Implicit Association Task (IAT) and the Picture Association Task (PAT), was capable of differentiating pedophiles from non-pedophiles, and whether the PAT, which allows separate analysis for male, female, boy and girl stimulus categories, was more sensitive to specific sexual associations in pedophiles than the IAT.

Characteristics of donors who do or do not return to give blood and barriers to their return.

Background: In the Netherlands about 50% of whole blood donors return to give blood after an invitation to donate. This study aimed to investigate the characteristics of donor return behaviour and to gain insight into the barriers to blood donation reported by the donors themselves.

Materials And Methods: A total of 4,901 whole blood donors were invited to donate in week 39 of 2009.

Thinking big: the effect of sexually objectifying music videos on bodily self-perception in young women.

The present study investigated the effect of sexually objectifying music video exposure on young women's implicit bodily self-perception and the moderating role of self-esteem. Fifty-six college women of normal weight were either exposed to three sexually objectifying music videos or three neutral music videos. Perceived and ideal body size were measured both before and after video exposure, using horizontally stretched and compressed photographs of the participant's own body in swimming garment.

Prosocial consequences of imitation.

Research has shown that helping behavior can be primed easily. However, helping decreases significantly in the presence of inhibition cues, signaling high costs for the executor. On the other hand, multiple studies demonstrated that helping behavior increases after being mimicked.

Those who laugh are defenseless: how humor breaks resistance to influence.

Three experiments illustrate that humor in advertisements prevents the development of negative brand associations due to resistance. Previous research on humor in advertising suggested that humor can counter negative responses during ad processing, but less is known about the effect of humor on the development of negative brand associations in memory. Brand associations are important because there is often a time delay between ad exposure and brand decisions.

Good morning creativity: task reactivation during sleep enhances beneficial effect of sleep on creative performance.

Both scientists and artists have suggested that sleep facilitates creativity, and this idea has received substantial empirical support. In the current study, we investigate whether one can actively enhance the beneficial effect of sleep on creativity by covertly reactivating the creativity task during sleep. Individuals' creative performance was compared after three different conditions: sleep-with-conditioned-odor; sleep-with-control-odor; or sleep-with-no-odor.

Do we act upon what we see? Direct effects of alcohol cues in movies on young adults' alcohol drinking.

Aims: Ample survey research has shown that alcohol portrayals in movies affect the development of alcohol consumption in youth. Hence, there is preliminary evidence that alcohol portrayals in movies also directly influence viewers' drinking of alcohol while watching movies. One process that might account for these direct effects is imitation.

Perspective taking eliminates differences in co-representation of out-group members' actions.

Coordinated action relies on shared representations between interaction partners: people co-represent actions of others in order to respond appropriately. However, little is known about the social factors that influence shared representations. We investigated whether actions performed by in-group and out-group members are represented differently, and if so, what role perspective-taking plays in this process.

When Pinocchio acts like a human, a wooden hand becomes embodied. Action co-representation for non-biological agents.

Action observation automatically activates corresponding motor representations in the observer, which is essential in coordinating actions with others. It is assumed that this co-representation system is activated by biological agents only. However, we often identify with biological agents, whereas this is not the case for non-biological agents.

Effects of alcohol portrayals in movies on actual alcohol consumption: an observational experimental study.

Aims: This study uses an experimental design to assess the effects of movie alcohol portrayal on alcohol consumption of young adults while watching a movie. Gender, weekly alcohol use and identification with the movie actor/character were assessed as moderators.

Design: A two (sex) × two (movie: alcohol or no portrayal of alcohol) between-subject design was used.

Neural correlates of emotional synchrony.

Facial expressions can trigger emotions: when we smile we feel happy, when we frown we feel sad. However, the mimicry literature also shows that we feel happy when our interaction partner behaves the way we do. Thus what happens if we express our sadness and we perceive somebody who is imitating us? In the current study, participants were presented with either happy or sad faces, while expressing one of these emotions themselves.
