How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

The model of action phases makes a distinction between motivational (goal setting) and volitional (goal implementation) phases of goal pursuit. The model implies that changing the behavior of individuals who are in a pre-decisional action phase (i.e., have not crossed the “Rubicon” yet with respect to turning their many wishes into binding goals) n...

Making if-then plans is a self-regulation strategy that facilitates goal attainment. An open question is, however, whether there are individual differences in if-then planning. We, therefore, developed and validated the If-Then Planning Scale (ITPS) in three independent studies with more than 2600 participants. The ITPS is conceptually grounded in...

Objective: Reducing face touching could help slow COVID-19’s spread. We tested whether implementation intentions, a simple-to-use behaviour change intervention, reduce face-touching behaviour effectively. Design: In this pre-registered online study, we utilised a novel way to collect behavioural data during a pandemic. We obtained video recordings...

Arguably, extreme sports athletes exhibit a more significant risk appetite than the general public. Are standard behavioral risk measures able to capture this? To answer this question, we assessed self-reports of risk taking and measured the risk-taking behavior of samples of snowboarders and climbers. Two groups of non-athletes, university student...

Disengaging from unattainable goals and reengaging in alternative goals is essential for effective goal pursuit; yet, surprisingly little is known about associated personality factors. Here, we focused on individual differences in self-control (domain-general self-control, if–then planning) and boredom (boredom proneness, boredom avoidance and esca...

Full-text available
Introduction: Boredom proneness is linked to poor self-regulation, leading to poor decision making and/or increased risk taking. These links have not yet been investigated in the domain of sports and exercise. However, poor decisions or excessive risk behavior would be highly detrimental to sporting performance and, in some cases, even cause physic...

The tendency to be overly confident in one’s future and skills has long been studied. More recently, a correlate of this overconfidence, the tendency to overclaim knowledge, has been in the focus of research. Its antecedents and downstream behavioral consequences are still in question. In a sample of undergraduate students (N = 168), we tested whet...

Background: Khat (Catha edulis) is a traditionally used substance in African and Arab countries that contains the amphetamine-like alkaloid cathinone. Khat use among Ethiopian students is a growing concern. This study aims to describe khat use, psychological problems, and motivation to change and to determine associated factors of khat use among st...

Public health campaigns often encourage people to increase the consumption of vegetables and fruits while limiting sugar, fat, and salt intake. Furthermore, recent approaches increasingly suggest accumulating small behavioral shifts to change eating behavior. However, when individuals actually do notice a positive change in their diet behavior has...

How can we maximize what is learned from a replication study? In the creative destruction approach to replication, the original hypothesis is compared not only to the null hypothesis, but also to predictions derived from multiple alternative theoretical accounts of the phenomenon. To this end, new populations and measures are included in the design...

Article
Drawing on the concept of a gale of creative destruction in a capitalistic economy, we argue that initiatives to assess the robustness of findings in the organizational literature should aim to simultaneously test competing ideas operating in the same theoretical space. In other words, replication efforts should seek not just to support or question...

The self-regulation strategy of forming implementation intentions has now been studied for almost 30 years. We trace the development of this research and explicate the questions that have been addressed. We then present current research that investigates the consequences of implementation intentions for flexible goal striving, behaviour in situatio...

Objective: Brief interventions based on personalized feedback have shown promising results in reducing risky alcohol use among university students. We investigated the effects of activating deliberative (predecisional) or implemental (postdecisional) mindsets on the effectiveness of a standardized brief intervention, the ASSIST-linked Brief Interve...

Objective: While behavioral recommendations regarding physical activity commonly focus on reaching demanding goals by proposing “thresholds,” little attention has been paid to the question of how much of a behavioral change is needed to make people feel that they have changed. The present research investigated this relation between actual and felt...

To what extent are research results influenced by subjective decisions that scientists make as they design studies? Fifteen research teams independently designed studies to answer five original research questions related to moral judgments, negotiations, and implicit cognition. Participants from two separate large samples (total N > 15,000) were th...

In this chapter, we introduce Mindset theory of Action Phases (MAP) and the self-regulation strategy of implementation intentions. MAP proposes four successive distinct phases through which one traverses during goal pursuit. During each phase, the goal-striving individual faces different challenges, and the activation of specific cognitive procedur...

In two experiments, we investigated the downstream consequences of activating deliberative versus implemental mindsets on risk perception (Experiment 1) and risk-taking behavior (Experiment 2). We hypothesized that participants in an implemental versus deliberative mindset arrive at more optimistic judgments about their own risks of experiencing ne...
