    • A novel experimental paradigm with improved ecological validity reveals robust action-associated enhancement of the N1 visual event-related potential in healthy adults 

      Balla, Viktória Roxána; Szalóki, Szilvia; Kilencz, Tünde; Dalos, Vera Daniella; Németh, Roland; Csifcsak, Gabor (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-11)
      The association between an action and its sensory consequence has been linked to our sense of agency (SoA). While ecological validity is crucial in investigating such a complex phenomenon, previous paradigms focusing on the cortical analysis of movement-related images used simplified experimental protocols. Here, we examined the influence of action-associated predictive processes on visual event-related ...
    • Internalizing problems and attentional control: Effects on cardiac autonomic responses after the induction of negative affect 

      Andersen, Tonje Grønning; Fiskum, Charlotte; Aslaksen, Per M; Flaten, Magne Arve; Jacobsen, Karl Henry (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      Individuals with internalizing problems differ in levels of attentional control (AC), and this heterogeneity could be associated with differences in autonomic arousal. The present study investigated whether AC moderated the effect of internalizing problems on self-reported experience and autonomic nervous system (ANS) responses after the induction of negative affect. Children aged 9–13 years were ...
    • Increasing propensity to mind‐wander by transcranial direct current stimulation? A registered report 

      Boayue, Nya Mehnwolo; Csifcsak, Gabor; Aslaksen, Per M; Turi, Zsolt; Antal, Andrea; Groot, Josephine Maria; Hawkins, Guy E.; Forstmann, Birte U.; Opitz, Alexander; Thielscher, Axel; Mittner, Matthias (Journal article; Tidsskriftartikkel, 2019-01-24)
      Transcranial direct current stimulation (tDCS) has been proposed to be able to modulate different cognitive functions. However, recent meta‐analyses conclude that its efficacy is still in question. Recently, an increase in subjects’ propensity to mind‐wander has been reported as a consequence of anodal stimulation of the left dorsolateral prefrontal cortex (Axelrod et al., Proceedings of the National ...
    • Mild Effect of Nalmefene on Alcoholic Cue-Induced Response Invigoration in Alcohol Use Disorder Without Accompanying Changes in Electrophysiological Signatures of Early Visual Processing and Executive Control 

      Gál, Bernadett Ildikó; Kilencz, Tunde; Albert, Anita; Demeter, Ildikó; Hegedűs, Klára Mária; Janka, Zoltán; Csifcsak, Gabor; Álmos, Péter Zoltán (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-26)
      Nalmefene is approved for as-needed pharmacological treatment in alcohol use disorder (AUD) by the European Medicines Agency. While the cellular effects of nalmefene have been thoroughly investigated, data are very limited on how this agent influences neural signals associated with inhibitory control and the visual analysis of environmental cues. This double-blind crossover study assessed the ...
    • Profiles of Perfectionism Among Adolescents Attending Specialized Elite- and Ordinary Lower Secondary Schools: A Norwegian Cross-Sectional Comparative Study 

      Stornæs, Annett Victoria; Rosenvinge, Jan H; Sundgot-Borgen, Jorunn; Pettersen, Gunn; Friborg, Oddgeir (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-06)
      The versatile construct of perfectionism has been heavily debated, e.g., its nature or measurement constituents, how it influences performances or, most importantly, our health. Conventional linear analyses seem inadequate to address such challenges. Hence, we used a latent variable and a person-centered approach to identify different patterns of perfectionism, and their relationships with psychological ...
    • No evidence that portion size influences food consumption in male Sprague Dawley rats 

      Naneix, Fabien; Pinder, Sophie C.; Summers, Megan Y.; Rouleau, Renee M.; Robinson, Eric; Myers, Kevin P.; McCutcheon, James E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-18)
      In studies of eating behavior that have been conducted in humans, the tendency to consume more when given larger portions of food, known as the portion size effect (PSE), is one of the most robust and widely replicated findings. Despite this, the mechanisms that underpin it are still unknown. In particular, it is unclear whether the PSE arises from higher-order social and cognitive processes that ...
    • Early maladaptive schemas as predictors of maternal bonding to the unborn child 

      Nordahl, Dag; Høifødt, Ragnhild Sørensen; Bohne, Agnes; Landsem, Inger Pauline; Wang, Catharina Elisabeth Arfwedson; Thimm, Jens (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-11)
      <p><i>Background - </i>The quality of an expectant mother’s bonding to the fetus has been shown to be associated with important developmental outcomes. Previous studies suggest that bonding quality is predicted by, for example, social support, psychological well-being, and depression. However, little is known regarding the role of maternal cognition in maternal-fetal bonding. Early maladaptive schemas ...
    • 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 ...
    • Gender differences in the bidirectional relationship between alcohol consumption and sleeplessness: the Tromsø study 

      Rognmo, Kamilla; Bergvik, Svein; Rosenvinge, Jan H; Bratlid, Katja Lovise; Friborg, Oddgeir (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-29)
      <i>Background</i> - The degree to which the relationship between alcohol use and sleeplessness is unidirectional or reciprocal is unclear due to great variation among the results of previous studies. The aim of the present study was to investigate if the relationship between alcohol use and sleeplessness is bidirectional by exploring how the change in and stability of alcohol use were related to ...
    • Defining compulsive exercise in eating disorders: acknowledging the exercise paradox and exercise obsessions 

      Bratland-Sanda, Solfrid; Mathisen, Therese Fostervold; Sundgot-Borgen, Jorunn; Rosenvinge, Jan H (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-04)
      Recently Dittmer et al. (JED 6:1–9, 2018). suggested a transdiagnostic definition and a clinical assessment for compulsive exercise in adolescents and adults with eating disorders. In this letter to the editor, we extend the transdiagnostic bridge to the DSM-5-criteria for obsessive-compulsive disorders and hence raise the issue of exercise obsession without compulsive exercise actions. We argue ...
    • 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 ...
    • Men in communal roles. The influence of gender incongruent role models on gender stereotypes and occupational aspirations of kindergarten children in Northern Norway 

      Ofori, George Kwadwo (Master thesis; Mastergradsoppgave, 2018-05-02)
      Research in the past has looked extensively at gender segregation in the workforce, where men and women are “divided” into bigger domains of work based on traditional gender roles attributed to them (Watt, 2008; Tellhed, Bäckström & Björklund, 2016). These two domains are STEM: science, technology, engineering, and mathematics (Beede et al., 2011) and HEED: healthcare, elementary education, and ...
    • The thrill of speedy descents: A pilot study on differences in facially expressed online emotions and retrospective measures of emotions during a downhill mountain-bike descent 

      Hetland, Audun; Kjelstrup, Eirik Refsnes; Mittner, Matthias; Vittersø, Joar (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-02)
      When extreme sport athletes explain the engagement behind their taxing and risky endeavors, they often refer to the happiness generated by the activities. However, during the activity, these athletes seem neither pleased nor happy. This article proposes some answers from a study of facially expressed emotions measured moment by moment during downhill mountain biking. Self-reported emotions were ...
    • Does the Flipped Classroom Improve Student Learning and Satisfaction? A Systematic Review and Meta-Analysis 

      Låg, Torstein; Sæle, Rannveig Grøm (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-20)
      We searched and meta-analyzed studies comparing flipped classroom teaching with traditional, lecture-based teaching to evaluate the evidence for the flipped classroom’s influence on continuous-learning measures, pass/fail rates, and student evaluations of teaching. Eight electronic reference databases were searched to retrieve relevant studies. Our results indicate a small effect in favor of the ...

    • 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 ...
    • Neural cell adhesion molecule Negr1 deficiency in mouse results in structural brain endophenotypes and behavioral deviations related to psychiatric disorders 

      Singh, Katyayani; Jayaram, Mohan; Kaare, Maria; Leidmaa, Este; Jagomäe, Toomas; Heinla, Indrek; Hickey, Miriam A.; Kaasik, Allen; Schäfer, Michael K.; Innos, Jürgen; Lilleväli, Kersti; Philips, Mari-Anne; Vasar, Eero (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-01)
      Neuronal growth regulator 1 (NEGR1) belongs to the immunoglobulin (IgLON) superfamily of cell adhesion molecules involved in cortical layering. Recent functional and genomic studies implicate the role of NEGR1 in a wide spectrum of psychiatric disorders, such as major depression, schizophrenia and autism. Here, we investigated the impact of <i>Negr1</i> deficiency on brain morphology, neuronal ...
    • Playing a video game is more than mere procrastination 

      Nordby, Kent; Løkken, Ronny Andre; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-13)
      <i>Background</i>: Procrastination is seen as a severe problem among young people, and many factors have been claimed to be associated with it, playing video games being one of them. One of the reasons why video games might be related to procrastination is their ability to offer instant gratification and feedback, while at the same time offer distractions from less tempting and rewarding tasks. ...
    • Modeling distracted performance 

      Hawkins, Guy E.; Mittner, Matthias; Forstmann, Birte U.; Heathcote, Andrew (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-23)
      The sustained attention to response task (SART) has been the primary method of studying the phenomenon of mind wandering. We develop and experimentally test the first integrated cognitive process model that quantitatively explains all stationary features of behavioral performance in the SART. The model assumes that performance is generated by a competitive race between a stimulus-related decision ...
