    • Managing Risk of Non-Communicable Diseases in Women with Bulimia Nervosa or Binge Eating Disorders: A Randomized Trial with 12 Months Follow-Up 

      Mathisen, Therese Fostervold; Sundgot-Borgen, Jorunn; Rosenvinge, Jan H; Bratland-Sanda, Solfrid (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-03)
      Persons with bulimia nervosa (BN) or binge eating disorder (BED) have an elevated risk of non-communicable diseases (NCDs). However, lowering this risk is rarely addressed in standard cognitive-behavioral treatment (CBT). We aimed to compare CBT with an intervention combining physical exercise and dietary therapy (PED-t), and hypothesized that the PED-t would do better than CBT in lowering the risk ...

      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) ...
    • Hippocampal Subfields in Adolescent Anorexia Nervosa 

      Myrvang, Anna Dahl; Vangberg, Torgil Riise; Stedal, Kristin; Rø, Øyvind; Endestad, Tor; Rosenvinge, Jan H; Aslaksen, Per M (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-25)
      Patients with anorexia nervosa (AN) exhibit volume reduction in cerebral gray matter (GM), and several studies report reduced hippocampus volume. The hippocampal subfields (HS) are functionally and structurally distinct, and appear to respond differently to neuropathology. The aim of this study was to investigate HS volumes in adolescent females with restrictive AN compared to a healthy age-matched ...
    • 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, 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 ...

From video‐recorded data, movement ...
    • Mate Choice could be Random in Female Rats (Rattus norvegicus) 

      Le Moëne, Olivia; Snoeren, Eelke (Journal article; Tidsskriftartikkel, 2017-11-01)
      Female mate choice is often investigated in terms of reproductive success in order to understand how male characteristics contribute to sexual attractiveness. Previous studies have found that females rats prefer mating with their first encounter rather than males visited subsequently, suggesting that the rewarding value of this first encounter is enough to reinforce mating with the first partner. ...

    • Does exposure to counterstereotypical role models influence girls' and women's gender stereotypes and career choices? A review of social psychological research 

      Olsson, Maria; Martiny, Sarah E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-07)
      Gender roles are formed in early childhood and continue to influence behavior through adolescence and adulthood, including the choice of academic majors and careers. In many countries, men are underrepresented in communal roles in health care, elementary education, and domestic functions (HEED fields, Croft et al., 2015), whereas women are underrepresented in the science, technology, engineering, ...

      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 ...
    • Communicating public avalanche warnings – what works? 

      Engeset, Rune; Pfuhl, Gerit; Landrø, Markus; Mannberg, Andrea; Hetland, Audun (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-20)
      Like many other mountainous countries, Norway has experienced a rapid increase in both recreational winter activities and fatalities in avalanche terrain during the past few decades: during the decade 2008–2017, 64 recreational avalanche fatalities were recorded in Norway. This is a 106% increase from that of the previous decade. In 2013, Norway therefore launched the National Avalanche Warning ...
    • Discrepancies in the spiking threshold and frequency sensitivity of nocturnal moths explainable by biases in the canonical auditory stimulation method 

      Thevenon, Hervé Emile Louis; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-11)
      The auditory stimulation method used in experiments on moth A cell(s) is generally believed to be adequate to characterize the encoding of bat echolocation signals. The stimulation method hosts, though, several biases. Their compounded effects can explain a range of discrepancies between the reported electrophysiological recordings and significantly alter the current interpretation. To test the ...

    • The relation of hippocampal subfield volumes to verbal episodic memory measured by the California Verbal Learning Test II in healthy adults 

      Aslaksen, Per M; Bystad, Martin Kragnes; Ørbo, Marte; Vangberg, Torgil Riise (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-08)
      Total hippocampal volume has previously been shown to correlate with performance on tests for verbal episodic memory. However, there are sparse evidence on how hippocampal subfield volumes are related to verbal episodic memory in healthy adults. The present study investigated the association between volumes of separate hippocampal subfields and verbal episodic memory performance in healthy volunteers. ...
    • The Opioid Receptor Mu 1 (OPRM1) rs1799971 and Catechol-O-methyltransferase (COMT) rs4680 as genetic markers for placebo analgesia 

      Aslaksen, Per M; Forsberg, June Thorvaldsen; Gjerstad, Johannes (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-16)
      The placebo effect is considered the core example of mind-body interactions. However, individual differences produce large placebo response variability in both healthy volunteers and patients. The placebo response in pain, placebo analgesia, may be dependent on both the opioid system and the dopaminergic system. Previous studies suggest that genetic variability affects the function of these 2 systems. ...
