  • Prolonged rather than hasty decision-making in schizophrenia using the box task. Must we rethink the jumping to conclusions account of paranoia? 

    Moritz, Steffen; Scheunemann, Jakob; Lüdtke, Thies; Westermann, Stefan; Pfuhl, Gerit; Balzan, Ryan P; Andreou, Christina (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-05)
    Jumping to conclusions (JTC) is the best established cognitive bias in schizophrenia and is increasingly targeted in interventions aimed to improve positive symptoms. To address shortcomings of the standard measure to capture JTC, the beads task, we developed a new variant—the box task—which was subsequently validated in people with elevated psychotic-like experiences. For the first time, the box ...
  • Bayesian analysis of risk- and ambiguity aversion in two information sampling tasks 

    Klevjer, Kristoffer; Pfuhl, Gerit (Conference object; Konferansebidrag, 2020-07)
    Humans are aversive to risk (irreducible uncertainty) and ambiguity (reducible uncertainty). However, strong ambiguity aversion does not necessarily imply strong risk aversion. Further, in real life it can be challenging to attribute uncertainty and one may treat ambiguity as risk. This can lead to biases in information sampling, i.e. premature stopping of collecting information that could ...
  • Perceived efficacy of COVID-19 restrictions, reactions and their impact on mental health during the early phase of the outbreak in six countries 

    Mækelæ, Martin Jensen; Reggev, Niv; Dutra, Natalia; Tamayo, Ricardo; Silva-Sobrinho, Reinaldo; Klevjer, Kristoffer; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-12)
    The COVID-19 pandemic forced millions of people to drastically change their social life habits as governments employed harsh restrictions to reduce the spread of the virus. Although beneficial to physical health, the perception of physical distancing and related restrictions could impact mental health. In a pre-registered online survey, we assessed how effective a range of restrictions were perceived, ...
  • Psychosis and Psychotic-Like Symptoms Affect Cognitive Abilities but Not Motivation in a Foraging Task 

    ten Velden Hegelstad, Wenche; Kreis, Isabel Viola; Tjelmeland, Håkon; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-31)
    <i>Background and Objective</i>: Goal-directed behavior is a central feature of human functioning. It requires goal appraisal and implicit cost-benefit analyses, i.e., how much effort to invest in the pursuit of a certain goal, against its value and a confidence judgment regarding the chance of attainment. Persons with severe mental illness such as psychosis often struggle with reaching goals. ...

  • Weak rTMS-induced electric fields produce neural entrainment in humans 

    Zmeykina, Elina; Mittner, Matthias; Paulus, Walter; Turi, Zsolt (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-20)
    Repetitive transcranial magnetic stimulation (rTMS) is a potent tool for modulating endogenous oscillations in humans. The current standard method for rTMS defines the stimulation intensity based on the evoked liminal response in the visual or motor system (e.g., resting motor threshold). The key limitation of the current approach is that the magnitude of the resulting electric field remains elusive. ...
  • Is physical exercise and dietary therapy a feasible alternative to cognitive behavior therapy in treatment of eating disorders? A randomized controlled trial of two group therapies 

    Mathisen, Therese Fostervold; Rosenvinge, Jan H; Friborg, Oddgeir; Vrabel, KariAnne; Bratland-Sanda, Solfrid; Pettersen, Gunn; Sundgot-Borgen, Jorunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-16)
    <i>Objective</i>: To compare effects of physical exercise and dietary therapy (PED‐t) to cognitive behavioral therapy (CBT) in treatment of bulimia nervosa (BN) and binge‐eating disorder (BED).<p> <p><i>Method</i>: The active sample (18–40 years of age) consisted of 76 women in the PED‐t condition and 73 in the CBT condition.

  • Female rat sexual behavior is unaffected by perinatal fluoxetine exposure 

    Hegstad, Jan; Huijgens, Patty; Houwing, Danielle; Olivier, Jocelien; Heijkoop, Roy; Snoeren, Eelke (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-22)
    Serotonin plays an important role in adult female sexual behavior, however little is known about the influence of serotonin during early development on sexual functioning in adulthood. During early development, serotonin acts as neurotrophic factor, while it functions as a modulatory neurotransmitter in adulthood. The occurrence of serotonin release, could thus have different effects on behavioral ...
  • Utfordringer på doktorgradsveien. Faktorer som kan forebygge eller øke stress hos doktorgradsstudenter 

    Flægstad, Tarjei Koren; Nilsen, Hans Olaf (Master thesis; Mastergradsoppgave, 2018-08-01)
    Av doktorgradsstudenter på norske universiteter, er det en fjerdedel som ikke fullfører innen normert tid. Det er lite forskning på hvorfor det er slik i Norge. Å øke gjennomstrømningen vil være nyttig for stipendiaten og har samfunnsøkonomisk gevinst. Denne studien har sett på faktorer som kan virke inn på engasjement og utbrenthet hos norske doktorgradsstudenter. Økt engasjement og mindre utbrenthet ...

  • Theta-gamma cross-frequency transcranial alternating current stimulation over the trough impairs cognitive control 

    Turi, Zsolt; Mittner, Matthias; Lehr, Albert; Bürger, H; Antal, Andrea; Paulus, Walter (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-15)
    Cognitive control is a mental process, which underlies adaptive goal-directed decisions. Previous studies have linked cognitive control to electrophysiological fluctuations in the theta band and theta-gamma cross-frequency coupling (CFC) arising from the cingulate and frontal cortices. Yet, to date the behavioral consequences of different forms of theta-gamma CFC remain elusive. Here, we studied the ...
  • pypillometry: A Python package for pupillometric analyses 

    Mittner, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-02)
    The size of the human pupil is controlled by pairs of constrictor and dilator muscles that allow its opening (dilation) and closing (constriction) in response to varying lighting conditions (Mathôt, 2018). Importantly, it has long been known that the pupil also reacts to psychological important stimuli (Hess & Polt, 1960) and has been a firmly established tool for studying “mental effort” in the ...
  • Objective Versus Subjective Effort in Schizophrenia 

    Kreis, Isabel Viola; Moritz, Steffen; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-09)
    <i>Background and Objectives</i>: Performance on cognitive tasks is often impaired in individuals with schizophrenia (SCZ), possibly resulting from either cognitive deficits (e.g., limited working memory capacity) or diminished mental effort or both. Investment of mental effort itself can be affected by cognitive resources, task load, and motivational factors and has thus proven difficult to measure. ...
  • Mestring i mottak og kommuner. Implementering og evaluering av Teaching Recovery Techniques i asylmottak, omsorgssentre og bosettingskommuner i Norge 

    Oppedal, Brit; Solhaug, Anne Kristine Nilsen; Friborg, Oddgeir; Biele, Guido (Research report; Forskningsrapport, 2019-03)
    Det er mangel på forskningsbaserte lavterskeltiltak som kan tilbys mange unge asylsøkere og flyktninger og avhjelpe traumerelaterte psykiske plager på relativt kort tid. Hensikten med denne rapporten er å informere om resultatene fra prosjektet Mestring i Mottak og Kommuner (MiMK), som evaluerte effekten av en lavterskelintervensjon for å redusere traumerelaterte psykiske plager blant asylsøkende ...
  • Adult attachment style and maternal-infant bonding: the indirect path of parenting stress 

    Nordahl, Dag; Rognmo, Kamilla; Bohne, Agnes; Landsem, Inger Pauline; Moe, Vibeke; Wang, Catharina Elisabeth Arfwedson; Høifødt, Ragnhild Sørensen (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-08)
    <i>Background</i> - The quality of maternal-infant bonding is related to important child outcomes. The literature has assumed that the ability to form relationships is a relatively stable trait, and research studies have suggested that a mother’s attachment style in close adult relationships is related to mother-infant bonding. The transition to parenthood is also often stressful, and the adult ...
  • Does Religion Matter? Italians' Responses towards Muslim and Christian Arab Immigrants as a function of their Acculturation Preferences 

    Matera, Camilla; Picchiarini, Anna; Olsson, Maria; Brown, Rupert (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-12)
    A 2 × 2 × 2 experiment examined the role of immigrants’ religion and perceived acculturation strategy on majority members’ attitudes. Acculturation strategies were manipulated along the two dimensions of contact and culture maintenance. Italian majority members (N = 247) read fictitious but seemingly real interviews with Arab immigrants, in which the immigrants’ religion (Muslim vs. Christian) and ...
