    • Action-associated modulation of visual event-related potentials evoked by abstract and ecological stimuli 

      Csifcsak, Gabor; Balla, Viktoria Roxana; Dalos, Vera Daniella; Kilencz, Tunde; Biro, Edit Magdolna; Urban, Gabor; Szaloki, Szilvia (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-09-19)
      This study investigated the influence of action‐associated predictive processes on visual ERPs. In two experiments, we sought evidence for sensory attenuation (SA) indexed by ERP amplitude reductions for self‐induced stimuli when compared to passive viewing of the same images. We assessed if SA is (a) present for both ecological and abstract stimuli (pictures depicting hands or checkerboards), (b) ...
    • Adolescent health and adaptation in Canada: Examination of gender and age aspects of the healthy immigrant effect 

      Kwak, Kyunghwa; Rudmin, Floyd Webster (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-11-14)
      Introduction A longstanding and widely held assumption is that immigrants suffer from ill health and adaptation problems. Yet recent studies show that immigrants report the same or better state of health compared to their native-born counterparts. This phenomenon, known as the healthy immigrant effect, has been found in studies of specific health conditions of adults. The present study focuses instead ...
    • Analyzing buyer behavior when selecting green criteria in public procurement 

      Igarashi, Mieko; De Boer, Luitzen; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
      Given the complexity of green public procurement, decisions are likely to be driven by bounded rationality. However, we know little about what determines supplier selection criteria in any given situation. This study explores buyer behavior when considering environmental criteria. We first conducted interviews and identified 12 operational procedures used by buyers. We then developed a survey to ...
    • Are adolescent elite athletes less psychologically distressed than controls? A cross-sectional study of 966 Norwegian adolescents 

      Rosenvinge, Jan H; Sundgot-Borgen, Jorunn; Pettersen, Gunn; Martinsen, Marianne; Stornæs, Annett Victoria; Pensgaard, Anne Marte (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-16)
      <p><i>Introduction</i>: Psychological distress is increasing among adolescents and clusters with other mental health problems such as eating problems. The aim of this study was to investigate the prevalence of psychological distress among young elite athletes and age-matched controls and whether prevalence figures may be attributed to perfectionism and eating problems.</p> <p><i>Methods</i>: ...
    • Are psychotic experiences related to poorer reflective reasoning? 

      Mækelæ, Martin Jensen; Moritz, Steffen; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-12)
      <p><i>Background</i>: Cognitive biases play an important role in the formation and maintenance of delusions. These biases are indicators of a weak reflective mind, or reduced engaging in reflective and deliberate reasoning. In three experiments, we tested whether a bias to accept non-sense statements as profound, treat metaphorical statements as literal, and suppress intuitive responses is related ...
    • Assessment of sexual behavior in rats: the potentials and pitfalls 

      Heijkoop, Roy; Huijgens, Patty Thalia; Snoeren, Eelke (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 ...
    • Association-based Concealed Information Test: A Novel Reaction Time-Based Deception Detection Method 

      Lukacs, Gaspar; Bartosz, Gula; Szegedi-Hallgato, Emese; Csifcsak, Gabor (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: ...
    • Attitudes of mental health providers towards adoption of evidence-based interventions: relationship to work-place, staff roles and social and psychological factors at work 

      Rye, Marte; Friborg, Oddgeir; Skre, Ingunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-08)
      <p><i>Background - </i>Gaining insight into factors influencing the adoption of evidence-based interventions (EBI) is essential to ensuring their sustainability in the mental healthcare setting. This article describes 1) differences between professional staff roles in attitudes towards EBI and 2) individual and organizational predictors of attitudes towards adopting EBI. <p><i>Methods - </i>The ...
    • Bare noen bokstaver? 

      Gorecka, Marta Maria (Chronicle; Kronikk, 2015)
    • A Bayesian perspective on delusions: Suggestions for modifying two reasoning tasks 

      Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08)
      Background and objectives:<br>There are a range of mechanistic explanations on the formation and maintenance of delusions. Within the Bayesian brain hypothesis, particularly within the framework of predictive coding models, delusions are seen as an aberrant inference process characterized by either a failure in sensory attenuation or an aberrant weighting of prior experience. Testing of these ...
    • Behavioral responses to emotional challenges in female rats living in a seminatural environment: The role of estrogen receptors 

      Le Moëne, Olivia; Ågmo, Anders j (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-11-06)
      Estrogen receptors (ERs) are involved in sexual as well as non-sexual behaviors. In the present study we assessed the effects of stimuli inducing positive or negative affect on sociosexual, exploratory and fear-related behaviors of female rats housed in groups (4 females, 3 males) in a seminatural environment. Ovariectomized females were treated with oil, 17β‑estradiol benzoate (EB, 18 μg/kg), the ...
    • Blame it on the weather? The association between pain in fibromyalgia, relative humidity, temperature and barometric pressure 

      Fagerlund, Asbjørn Johansen; Iversen, Maria; Ekeland, Andrea; Moen, Connie Malén; Aslaksen, Per M (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-10)
      Self-reported pain levels in patients with fibromyalgia may change according to weather conditions. Previous studies suggest that low barometric pressure (BMP) is significantly related to increased pain, but that the contribution of changes in BMP has limited clinical relevance. The present study examined whether BMP influenced variability in perceived stress, and if stress levels moderated or ...
    • Blinding is compromised for transcranial direct current stimulation at 1 mA for 20 min in young healthy adults 

      Turi, Zsolt; Csifcsak, Gabor; Boayue, Nya Mehnwolo; Aslaksen, Per M; Antal, Andrea; Paulus, Walter; Groot, Josephine; Hawkins, Guy E.; Opitz, Alexander; Thielscher, Axel; Mittner, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-19)
      Transcranial direct current stimulation (tDCS) is a non‐invasive brain stimulation method that is frequently used to study cortical excitability changes and their impact on cognitive functions in humans. While most stimulators are capable of operating in double‐blind mode, the amount of discomfort experienced during tDCS may break blinding. Therefore, specifically designed sham stimulation protocols ...
    • Body composition and physical fitness in women with bulimia nervosa or binge-eating disorder. 

      Mathisen, Therese Fostervold; Rosenvinge, Jan H; Friborg, Oddgeir; Pettersen, Gunn; Stensrud, Trine; Hansen, Bjørge Hermann; Underhaug, Karoline; Teinung, Elisabeth; Vrabel, KariAnne; Svendsen, Mette; Bratland-Sanda, Solfrid; Sundgot-Borgen, Jorunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-23)
      <p><i>Objective</i>: Knowledge about physical fitness in women with bulimia nervosa (BN) or binge‐eating disorder (BED) is sparse. Previous studies have measured physical activity largely through self‐report, and physical fitness variables are mainly restricted to body mass index (BMI) and bone mineral density. We expanded the current knowledge in these groups by including a wider range of physical ...
    • Bullying Among Hospital Staff : Use of Psychometric Triage to Identify Intervention Priorities 

      Eriksen, Geir Steinar; Nygren, Ivan; Rudmin, Floyd Webster (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Survey of workplace bullying in a Norwegian hospital found that 10% of nurses, therapists, and physicians (N=440) had witnessed bullying. Negative Acts Questionnaire (NAQ) scores were low, Minnesota Satisfaction Questionnaire (MSQ) scores were positive, and Organizational Commitment Questionnaire (OCQ) scores were neutral. NAQ scores and having witnessed bullying both predicted low MSQ scores, ...
    • The Category-Focus Implicit Association Test 

      González, Roberto; Siebler, Frank; Ordóñez, Gabriela; Bohner, Gerd; Haye, Andrés; Sirlopú, David; Millar, Andres; De Tezanos-Pinto, Pablo; Torres, David (Journal article; Tidsskriftartikkel; Peer reviewed, 2010)
    • Cerebrospinal fluid neurogranin/β-site APP-cleaving enzyme 1 predicts cognitive decline in preclinical Alzheimer's disease 

      Kirsebom, Bjørn-Eivind; Nordengen, Kaja; Selnes, Per; Waterloo, Knut; Torsetnes, Silje Bøen; Gísladóttir, Berglind; Brix, Britta; Vanmechelen, Eugeen; Bråthen, Geir; Hessen, Erik; Aarsland, Dag; Fladby, Tormod (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-10)
      <i>Introduction</i>: The cerebrospinal fluid neurogranin (Ng)/β-site amyloid precursor protein-cleaving enzyme 1 (BACE1) ratio may reflect synaptic affection resulting from reduced beta-amyloid (Aβ) clearance. We hypothesize that increased Ng/BACE1 ratio predicts the earliest cognitive decline in Alzheimer’s disease.<p> <p><i>Methods</i>: We compared Ng/BACE1 levels between cases with subjective ...
    • Change in physical activity is not associated with change in mental distress among adolescents: The Tromsø Study: Fit Futures 

      Opdal, Ida Marie; Morseth, Bente; Handegård, Bjørn Helge; Lillevoll, Kjersti; Ask, Helga; Nielsen, Christopher Sivert; Horsch, Alexander; Furberg, Anne-Sofie; Rosenbaum, Simon; Rognmo, Kamilla (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-09)
      <i>Background</i>: Previous research shows that physical activity has a protective effect on mental distress in adults, but the relationship is less researched and seems more ambiguous for adolescents. Studies in this field have typically been cross-sectional by design and based on self-reported physical activity measures, which are known to be vulnerable to response bias. The aim of this study ...
