Few studies have investigated the functional networks of the brain in adolescent AN patients.. The aim of this explorative study was to investigate multiple ...
    • Amygdala's "unfelt" emotions? 

      Profeti, Italo (Master thesis; Mastergradsoppgave, 2008-05)
      Participants saw “hybrid” pictures of faces composed by superimposing neutral expression in high spatial frequencies (HSF, 7-128 cycles/image) over different emotional expressions in low spatial frequencies (LSF, 1-6 cycles). While explicitly judging them as neutral, participants rated the hybrids as friendly when the emotion showed in the low frequencies was positive, and as unfriendly when the ...

We systematically observed 53 parent–child dyads in consultation bureau waiting rooms and playgrounds. Twenty-three parents used their phone at least once during the observation. Across the dyads, we observed parent and child behavior during a total of 1,038 ten-second intervals. Of these ...
    • Are Personality Traits Related to how Healthy Adults Adjust Their Decision-Making Strategies Under Varying Levels of Reward and Loss Controllability? 

      Angen, Caroline Alexandra Grant (Mastergradsoppgave; Master thesis, 2022-05-16)
      Abstract Research suggests a dual-system theory of motivation on decision-making in humans, consisting of the Pavlovian and the Instrumental systems. These systems influence how we respond to environmental threats and rewards either in an automatic or in a more deliberate manner, and their interaction can either optimize or hinder decision-making. Importantly, humans seem to rely more heavily on ...
    • 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 ...
    • Are there Gender Differences in Pain and Placebo Analgesia? 

      Harviken, Ida Elisabeth (Master thesis; Mastergradsoppgave, 2014-05-02)
      Abstrakt Formål: Å undersøke om menn viser høyere placebo responser enn kvinner, og om dette kan forklares av kjønnsforskjeller i smertefrykt. Høyere grad av smertefrykt ble foreslått å være høyest blant kvinner, noe som antas å redusere deres placebo respons. Videre ble det undersøkt om kjønnet på eksperimentator kunne påvirke deltagernes smerterapport. Metode:96 friske deltagere (51 kvinner) ble ...

    • 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: ...
    • Associations between self-compassion and complicated grief symptoms in bereaved individuals: An exploratory study 

      Vara, Helge; Thimm, Jens (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-08)
      Grief is a normal and natural response to the loss of a loved one that is characterized by a broad range of emotional, behavioral, cognitive, and physiological symptoms. For most bereaved, these symptoms abate over time as the individual comes to terms with the loss. However, about 10% of the bereaved experience a persistent and debilitating grief reaction, a condition that has been termed complicated ...
