Article
Anhedonia is a major public health concern and has proven particularly difficult to counteract. It has been hypothesized that anhedonia can be deterred by engagement in rewarding social and physical events. The aims of the present study were to examine (1) the effects of personalized lifestyle advice based on observed individual patterns of lifesty...

Objective: This study investigated whether low reward responsiveness marks vulnerability for developing depression in a large cohort of never-depressed 16-year-old adolescents who completed a reward task and were subsequently followed for 9 years, during which onset of depression was assessed. Method: Data were collected as part of the TRacking...

Background: There is evidence that reward responsiveness and optimism are associated with mental and social functioning in adolescence and adulthood, but it is unknown if this is also the case for young children. Part of the reason for this gap in the literature is that the instruments that are used to assess reward responsiveness and optimism in...

Context: Previous meta-analyses substantially contributed to our understanding of increased drug use risk in bullies but only included research up to 2014 and did not report on other types of substances. Objective: To review and meta-analyze existing evidence regarding the prospective association between peer bullying perpetration in childhood a...

It is plausible that peer aggression—like general forms of aggression—is transmitted from one generation to the next. As such, parental behavior in childhood and adolescence may be associated with offspring aggressive behavior against peers. This study used 1970 British Cohort Study data to test intergenerational transmission of peer aggression. Th...
Article
Full-text available
Twin studies suggest a substantial role for genes in explaining individual differences in aggressive behavior across development. It is unclear, however, how directly measured genetic risk is associated with aggressive behavior at different moments across adolescence and how genes might distinguish developmental trajectories of aggressive behavior....

Positieve informatie roept vaak sterke reacties op, maar niet bij iedereen. Wie minder sterk reageert op positieve informatie heeft een zogenaamde lage positieve bias. In dit onderzoek is nagegaan of zo’n lage positieve bias tijdens de adolescentie een voorspeller is van latere depressie en wat de implicaties zijn van een lage positieve bias in het...

The Domains Of Pleasure Scale (DOPS) is a newly developed questionnaire designed to measure the multifaceted aspects of pleasure. It assesses levels of pleasure across different domains (e.g., social, physical). The psychometric properties of the DOPS were tested in two studies (Study 1: N = 2937, Mage = 21.4 years, SD = 1.9; Study 2: N = 1187, Mag...

There is evidence that people commonly show a bias toward happy facial emotions during laboratory tasks, that is, they identify other people’s happy facial emotions faster than other people’s negative facial emotions. However, not everybody shows this bias. Individuals with a vulnerability for depression, for example, show a low happy bias compared...
Article
Full-text available
Background Anhedonia (loss of pleasure) is characterized by low responsiveness to rewards and, by virtue of being one of the two core symptoms of depression, by altered responses to stress. We investigated the effect of an acute stress experience (i.e., a tandem skydive) that was expected to elicit both intense fear and intense euphoria in a sample...
Data
Regression analyses for alpha-amylase reactivity and recovery on affect after the skydive, full model including all covariates. Note. BMI = Body Mass Index. (PDF)

Article
Full-text available
Anhedonia reflects a dysfunction in the reward system, which can be manifested in an inability to enjoy pleasurable situations (i.e., lack of positive emotions), but also by a lack of motivation to engage in pleasurable activities (i.e., lack of motivation). Little is known about the interrelations between positive emotions and motivation in daily...

Brain-derived neurotrophic factor (BDNF) is a protein often studied in psychiatric populations. Commercial ELISA kits have been validated for measuring BDNF in blood plasma and serum, but blood collection is an invasive method which cannot always be used. The aim of this pilot study was to explore the noninvasive alternative of measuring BDNF in sa...

Many psychiatric problem domains have been associated with emotion-specific biases or general deficiencies in facial emotion identification. However, both within and between psychiatric problem domains, large variability exists in the types of emotion identification problems that were reported. Moreover, since the domain-specificity of the findings...

Adolescent onset depression places a high burden on those who suffer from it, and is difficult to treat. An improved understanding of mechanisms underlying susceptibility to adolescent depression may be useful in early detection and as target in treatment. Facial emotion identification bias has been suggested as trait marker for depression, but res...

Background: Anhedonia is generally defined as the inability to feel pleasure in response to experiences that are usually enjoyable. Anhedonia is one of the two core symptoms of depression and is a major public health concern. Anhedonia has proven particularly difficult to counteract and predicts poor treatment response generally. It has often been...
Article
De Britse filosoof Gilbert Ryle (1900-1967) is vooral bekend geworden met zijn 'Concept of Mind' (1949). Dit werk is doorgaans gelezen als een behaviouristisch manifest. Dat wil zeggen dat Ryle de wereld van de geest zou hebben willen reduceren tot de zichtbare gedragingen van de mens. Charlotte Vrijen onderzocht Ryle's gepubliceerde oeuvre. Daarna...

In this project, we examine the effects of personalized lifestyle advice based on observed individual patterns of lifestyle behaviors and experienced pleasure in anhedonic young adults. Further, we explore whether a tandem skydive following the personalized lifestyle advice positively influences anhedonic young adults’ abilities to carry out the recommended lifestyle changes, and whether this ultimately improves their self-reported pleasure.
