Sleep is important for health and well-being. Nevertheless, sleep is disturbed in about 20% of the population (e.g., by insomnia) with cognition (e.g., recurrent thoughts, rumination, or worry) making sleep harder. This dissertation therefore describes three cognitive models that illustrate the influence of cognition on sleep. The first model describes how negative cognitive activity leads...

Measurement is fundamental in science. Social sciences generally and psychology, in particular, depend on objective, valid, and reliable psychometric scales. In the 20th century, the psychology of religion and spirituality spent a long time searching for comprehensive and trustworthy instruments to assess psychological constructs in the field of empirical studies of religion and spirituality....

In spite of advances made in therapeutic possibilities over the past decades, long-term treatment responses remain relatively discouraging, with relapse rates higher than for most other psychiatric disorders. The chronic disease course of substance use disorder (SUD) has led to debate whether...

The present thesis investigated how mental representations of rotation develop between 2 and 5.5 years of age. In Study 1, toddlers were presented with a rotating shape that disappeared briefly behind an occluder and reappeared either in its original or mirror-reversed form. Eye-tracking results showed that during visible rotation, toddlers between 2 and 3 years of age increasingly combined...

Le traumatisme de l’abus sexuel est un événement adverse qui cause des répercussions négatives sur la vie physique, psychologique et spirituelle de la victime. Nous remarquons que les recherches, dans les pays développés, sont plus avancées sur ce sujet que dans les pays du Moyen-Orient. En effet, au Liban, nous n’avons pas assez de recherches sur le thème de l’abus sexuel parce...

Relationship functioning can be investigated from different angles; next to investigating dyadic outcomes between couples we can also zoom into processes within subjects. Adopting a cultural lens adds another layer, as the cultural context influences norms around intimate relationships, and can be inspected using the framework of Bronfenbrenner´s (1977) ecological systems theory. In more...

Research on clinical populations with eating disturbances has shown the involvement of reward processing in the maintenance of disease- associated symptoms. Investigation on food as a reward indicates the metabolic or feeding state (i.e. fasted or fed state) as a modulator of food as a reward, but little is known about how these states influence other types of reward. This is important...

Visual selective attention prioritizes the processing of behaviorally relevant over irrelevant information, to optimize the use of limited cognitive resources in the brain. These selective mechanisms preferentially route relevant neuronal representations through a network of distributed brain regions. Previous studies suggested that selective information routing in the attention network may...

En utilisant des mesures comportementales et...
