  • 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 ...

  • 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 ...
  • It’s Been a Hard Day’s Night and I’ve Been Working Like a Dog: Workaholism and Work Engagement in the JD-R Model 

    Langseth-Eide, Benedicte (Journal article; Peer reviewed, 2019-06-21)
    The study investigates if the job-demands resources (JD-R) model could be improved by including workaholism in its health impairment process. Salient predictors and antecedents of workaholism and work engagement are identified in a sample of 12170 employees at Norwegian universities and university colleges. Structural equation modeling suggested that job demands and job resources relate to workaholism ...
  • Estrogen receptors α and β in the central amygdala and the ventromedial nucleus of the hypothalamus: Sociosexual behaviors, fear and arousal in female rats during emotionally challenging events 

    Le Moëne, Olivia; Stavarache, Mihaela; Ogawa, Sonoko; Musatov, Sergei; Ågmo, Anders (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-27)
    Estrogens receptors (ER) are involved in several sociosexual behaviors and fear responses. In particular, the ERα is important for sexual behaviors, whereas ERβ modulates anxiolytic responses. Using shRNA directed either against the ERα or the ERβ RNAs (or containing luciferase control) encoded within an adeno-associated viral vector, we silenced these receptors in the ventromedial nucleus of the ...
