Non-monetary reinforcement effects on pro-environmental behavior
Uncertainty causes humans to use social heuristics and to cooperate more: An experiment among Belgian university students
A Multilab Replication of the Ego Depletion Effect
There is an active debate regarding whether the ego depletion effect is real. A recent preregistered experiment with the Stroop task as the depleting task and the antisaccade task as the outcome task found a medium-level effect size. In the current research, we conducted a preregistered multilab replication of that experiment. Data from 12 labs across the globe ( N = 1,775) revealed a small and significant ego depletion effect, d = 0.10. After ex…

Engaging in self‐regulation results in low‐level construals
Previous research has suggested that self‐regulation results in low‐level construals but has inferred construal levels after self‐regulation only indirectly, through construal‐dependent judgments and choices. In the present paper, we demonstrate a direct link between engaging in self‐regulation and low‐level construals, by manipulating self‐regulation and subsequently assessing construal levels using well‐established and straightforward measures …
Self-Regulating Enhances Self-Regulation in Subsequent Consumer Decisions Involving Similar Response Conflicts
Ego depletion, the observation that self-regulation reduces subsequent self-regulation, is a remarkably robust phenomenon, and the generalization to the consumer domain appears undisputable. Contrary to most other self-regulatory situations, however, consecutive self-regulatory decisions in consumer settings tend to be similar in the control processes that they recruit. Three experiments demonstrate the pivotal role of similarity. When two consec…
The presence of aggression cues inverts the relation between digit ratio (2D): (4D) and prosocial behaviour in a dictator game
Digit ratio (2D:4D) is a sexually dimorphic trait. Men have relatively shorter index (2D) compared to ring (4D) fingers than women. More masculine ratios are thought to be influenced by higher prenatal testosterone levels. In the present paper, we aim to show the context-dependency of the relation between 2D:4D and social behaviour. In two studies, we expose participants either to control or to aggression cues. Afterwards, they make a decision in…
Positive cueing: Promoting sustainable consumer behavior by cueing common environmental behaviors as environmental
A subordinate status position increases the present value of financial resources for low 2D: 4D men
It has been suggested that the ratio of the length of the 2nd and 4th fingers (digit ratio or 2D:4D) is related to prenatal testosterone with lower ratios thought to be influenced by higher prenatal testosterone levels. Accordingly, low 2D:4D has been associated to a number of fitness‐related factors, such as high status in competitive sports and in music. Recent evidence suggests that 2D:4D is also related to economic decision making. We combine…
I felt low and my purse feels light: Depleting mood regulation attempts affect risk decision making
We propose that negative affect can induce people to engage in risky decisions. We test two alternative hypotheses as to how this effect may emerge. The mood repair hypothesis states that risky choices in risk decision making serve as a means to repair one's negative affect. The depletion hypothesis, in contrast, states that risky choices in risk decision making are the mere consequence of a state of depletion resulting from engagement in active …
Tempt Me Just a Little Bit More: The Effect of Prior Food Temptation Actionability on Goal Activation and Consumption
People are often exposed to actionable food temptations (i.e., an immediate opportunity to consume, like when friends offer cookies) and nonactionable food temptations (i.e., no immediate consumption opportunity, like ads for chocolate). The results of three experiments suggest that prior exposure to nonactionable food temptations does not prevent the activation of an eating goal, given a subsequent consumption opportunity, while prior exposure t…
Bikinis Instigate Generalized Impatience in Intertemporal Choice
Neuroscientific studies demonstrate that erotic stimuli activate the reward circuitry processing monetary and drug rewards. Theoretically, a general reward system may give rise to nonspecific effects: exposure to “hot stimuli” from one domain may thus affect decisions in a different domain. We show that exposure to sexy cues leads to more impatience in intertemporal choice between monetary rewards. Highlighting the role of a general reward circui…
Altruistic behavior as a costly signal of general intelligence
Wanting a Bit(e) of Everything: Extending the Valuation Effect to Variety Seeking
Markman and Brendl have demonstrated that individuals tend to regard as more valuable those objects that are able to satisfy an active desire. Building on their framework, we predicted that desire would enlarge the consideration set and, hence, affect variety-seeking tendencies in a product category. Our first study shows that hunger and visual food cues enhance variety seeking in food items. Further, by means of mediation analyses and a suppress…

The less I trust, the less I contribute (or not)?’ The effects of trust, accountability and self‐monitoring in social dilemmas
The present research examined the influence of trust, accountability, and self‐monitoring on individual decision makers' willingness to contribute in a give‐some game and in an experimental public goods dilemma. Previous research has shown that trust and contributions are positively related such that high trusters generally contribute more than low trusters. The present research questions the pervasiveness of this relation by arguing that low tru…

The role of different types of instrumentality in motivation, study strategies, and performance: Know why you learn, so you'll know what you learn
Background: Two theories in the field of motivation and achievement, namely the future time perspective theory and goal theory, result in conflicting recommendations for enhancing students' motivation, because of their differential emphasis on the task at hand and on the future consequences of a task.Aims: We will present a framework consisting of four types of instrumentality that combines both perspectives. The implications of those different t…

Wanting to have vs. wanting to be: The effect of perceived instrumentality on goal orientation
Two theories of motivation relevant to classroom learning result in conflicting recommendations for enhancing motivation and performance. The goal theory stresses only that stimulating an individual s natural curiosity will increase motivation. This theory relies on the distinction between intrinsic and extrinsic motivation. Future time perspective theory stresses the importance of the personal future for motivation and learning and the utility o…
