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....

Comorbidity with other disorders, such as Oppositional-Defiant Disorder (ODD) or Conduct Disorder (CD) are very common.

Pathological substance use is amongst the most persistent and costly ills of global modern society. 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...

The trauma resulting from sexual abuse is a difficult experience that causes negative physical, psychological and spiritual impact on the victim. Research on this topic is more advanced in developed countries than in the Middle East. Lebanon lacks sufficient research about sexual abuse since it is still a taboo subject especially among young men. Thus, in this research, we have decided to...

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...

In this thesis, I aimed to map the development of facial expression recognition from early childhood up to adulthood by identifying for the first time in the literature the quantity and quality of visual information needed to recognise the six 'basic' emotions. Using behavioural and eye tracking measures, the original contributions of this thesis include: 1. An unbiased fine-grained mapping of...
