Textual health warning labels on snus (Swedish moist snuff): do they affect risk perception?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-27)<p><i>Background</i>: To strengthen the risk message on snus warning labels, the European Union in 2016 removed “can” from the warning “This tobacco product (can) damages your health and is addictive.” We tested how these and other textual warnings affect risk perception.</p> <p><i>Methods</i>: Snus-using and non-using Norwegians aged 16–72 participated in two online survey experiments. ... -

The double-edged effect of intergroup similarity: Muslim and Christian immigrants’ acculturation preferences on intergroup relations in Sweden
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-21)A 2 x 2 x 2 experiment examined effects of the acculturation orientations seen to be endorsed by immigrants (of two different religions) on intergroup relations in Sweden. Swedish majority participants (N = 448) read interviews with Iraqi immigrants in which the immigrants’ religion (Muslim vs. Christian), desired level of contact with the host society (high vs. low), and desire to maintain their ... -
Assessment of sexual behavior in rats: the potentials and pitfalls
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-27)In the field of behavioral neuroscience, it is essential to use the appropriate animal models for the topic of investigation. Using the wrong model can result in false interpretation of the results. In this review we will discuss the animal models used to study sexual behavior, with a focus on rats. We will discuss the potentials and pitfalls of the different paradigms and try to make recommendations ... -
Six-year positive effects of a mindfulness-based intervention on mindfulness, coping and well-being in medical and psychology students; Results from a randomized controlled trial
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-24)Longitudinal research investigating the enduring impact of mindfulness training is scarce. This study investigates the six-year effects of a seven-week mindfulness-based course, by studying intervention effects in the trajectory of dispositional mindfulness and coping skills, and the association between those change trajectories and subjective well-being at six-year follow-up. 288 Norwegian medical ... -
Non-linear heart rate variability as a discriminator of internalizing psychopathology and negative affect in children with internalizing problems and healthy controls
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-23)Background: Internalizing psychopathology and dysregulated negative affect are characterized by dysregulation in the autonomic nervous system and reduced heart rate variability (HRV) due to increases in sympathetic activity alongside reduced vagal tone. The neurovisceral system is however, a complex nonlinear system, and nonlinear indices related to psychopathology are so far less studied in children. ... -
Optimizing the RMET to measure bias not performance differences
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-22)<p>Background: Human social interaction and communication is complex. Sending a verbal message is often accompanied by intonations, facial expressions, grimaces, and body postures. Nonverbal signals are potentially open for misinterpretation. One popular test for assessing the interpretation of facial expressions is the “Reading the Mind in the Eyes” Test (RMET). This test has been used to relate ... -
Patterns of change and stability in caregiver burden and life satisfaction from 1 to 2 years after severe traumatic brain injury: A Norwegian Longitudinal study.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-27)<p><i>OBJECTIVE</i>: To assess burden and life satisfaction in family members of patients with severe traumatic brain injury (sTBI) at 1 and 2 years post-injury, examine if change in burden can be predicted by family member and patient demographics, patient’s functional status, family members social network or level of burden at 1 year.</p> <p><i>METHODS</i>: Prospective national multicenter ... -
Developmental trend towards exact imitation in the second year of life: Evidence from a longitudinal study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-11)Findings from previous cross-sectional studies showed that while toddlers around their first birthday imitate selectively, that is, they systematically omit some kinds of target action steps or they copy only the goal, but not the means of the modeled actions, older toddlers imitate more exactly. The aim of the present article is to provide longitudinal evidence for this developmental trend and to ... -
Vocational identity development among unaccompanied refugee minors
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09)This study examined educational aspirations and vocational identity formation among unaccompanied refugees in Norway. In Phase 1 we employed questionnaire data from 918 unaccompanied refugees to investigate the effects of demographic information, pre-migration trauma, mental health and acculturation-related factors on their educational aspirations. In Phase 2, data from Identity Status Interviews ... -
Pros and Cons of Character Portrayals of Autism on TV and Film
(Journal article; Tidsskriftartikkel, 2017-11-23)Portrayals of characters with autism spectrum disorder (ASD) and/or with autistic traits on film and in TV-series are increasing. Such portrayals may contribute in increasing awareness of the condition but can also increase stereotypes. Thus, these character portrayals are subject to heated debate within the ASD-community, but also in the general public at large. Following our recent published study ... -
Tracking changes in spatial frequency sensitivity during natural image processing in school age: an event-related potential study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-09)Several studies have shown that behavioral and electrophysiological correlates of processing visual images containing low or high spatial frequency (LSF or HSF) information undergo development after early childhood. However, the maturation of spatial frequency sensitivity in school-age has been investigated using abstract stimuli only. The aim of the current study was to assess how LSF and HSF ... -
Resilience to Discrimination Among Indigenous Sami and Non-Sami Populations in Norway: The SAMINOR2 Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-21)Discrimination is generally negative for mental health and well-being; however, few studies have examined protective effects of resilience factors, especially among minority indigenous people. Here, we validated a short version of the Resilience Scale for Adults (RSA) and examined its protective effects against discrimination among Norwegian indigenous Sami and non-Sami populations. Data come from ... -

Association-based Concealed Information Test: A Novel Reaction Time-Based Deception Detection Method
(Journal article; Tidsskriftartikkel, 2017-07-15)In recent years, numerous studies were published on the reaction time (RT)-based Concealed Information Test (CIT). However, an important limitation of the CIT is the reliance on the recognition of the probe item, and therefore the limited applicability when an innocent person is aware of this item. In the present paper, we introduce an RT-based CIT that is based on item-category associations: ... -
