  • Spared performance but increased uncertainty in schizophrenia: Evidence from a probabilistic decision-making task 

    Kreis, Isabel Viola; Zhang, Lei; Moritz, Steffen; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2021)
    Aberrant attribution of salience to in fact little informative events might explain the emergence of positive symptoms in schizophrenia and has been linked to belief uncertainty. Uncertainty is thought to be encoded by neuromodulators, including norepinephrine. However, norepinephrinergic encoding of uncertainty, measured as task-related pupil dilation, has rarely been explored in schizophrenia. ...
  • Cutoff criteria for the placebo response: a cluster and machine learning analysis of placebo analgesia. 

    Aslaksen, Per M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-28)
    Computations of placebo effects are essential in randomized controlled trials (RCTs) for separating the specific effects of treatments from unspecific effects associated with the therapeutic intervention. Thus, the identification of placebo responders is important for testing the efficacy of treatments and drugs. The present study uses data from an experimental study on placebo analgesia to suggest ...
  • Here, there, and everywhere: Applying vignettes to investigate appraisals of job demands 

    Langseth-Eide, Benedicte; Vittersø, Joar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-21)
    The job characteristics literature has revealed that job demands can be differentiated into hindrance and challenge demands. However, there has been little consensus on this categorization. Additionally, studies have revealed that job demands can be perceived as hindering and challenging at the same time. The present study aims to bring nuance to this topic by investigating two job demands (i.e., ...
  • Substituting facial movements in singers changes the sounds of musical intervals 

    Laeng, Bruno; Kuyateh, Sarjo; Kelkar, Tejaswinee (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-17)
    Cross-modal integration is ubiquitous within perception and, in humans, the McGurk effect demonstrates that seeing a person articulating speech can change what we hear into a new auditory percept. It remains unclear whether cross-modal integration of sight and sound generalizes to other visible vocal articulations like those made by singers. We surmise that perceptual integrative effects should ...

  • The effects of virutal reality on procedural pain and anxiety in pediatrics: A systematic review and meta-analysis 

    Nordgård, Rikke Kathrine; Låg, Torstein (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-15)
    Distraction and procedural preparation techniques are frequently used to manage pain and anxiety in children undergoing medical procedures. An increasing number of studies have indicated that Virtual Reality (VR) can be used to deliver these interventions, but treatment effects vary greatly. The present study is a systematic review and meta-analysis of studies that have used VR to reduce procedural ...
  • The prevalence of potentially traumatic events in the seventh survey of the population-based Tromsø study (Tromsø 7) 

    Thimm, Jens; Rognmo, Kamilla; Rye, Marte; Flåm, Anna Margrete; Næss, Eva Therese; Skre, Ingunn; Wang, Catharina Elisabeth Arfwedson (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-20)
    Aims: Potentially traumatic events (PTEs) can have detrimental consequences for an individual’s physical and mental health. Exposure to PTEs is therefore increasingly assessed in population-based studies. Consistent with this trend, the most recent wave of the longitudinal population-based Tromsø study (Tromsø 7) in Northern Norway included a list of PTEs. The aim of the present study was to describe ...
  • Here's the TRIQ: The Tromsø Interest Development Questionnaire based on the four-phase model of interest development 

    Dahl, Tove I.; Nierenberg, Ellen (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-08)
    The Tromsø Interest Questionnaire (TRIQ) is the first suite of self-report subscales designed for focused investigations on how interest is experienced in relation to Hidi and Renninger’s four-phase model of interest development. In response to the plethora of varied interest measures that already exist in terms of theoretical grounding, form, and tested quality, the TRIQ subscales were designed ...
  • Napping alone in the snow and cuddling with mommy at night: An exploratory, qualitative study of Norwegian beliefs on infant sleep 

    Abels, Monika; Bosy, Caroline; Fredriksen, Ingrid-Camilla Myhre (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-23)
    This study addresses Norwegian infants’ sleeping places during the day and night. In the first part we asked the general public to indicate where they think infants should sleep by placing stickers on a depiction of different sleeping places. This revealed that infants were expected to predominantly sleep outside in a stroller during the day and either bedshare, room share or sleep independently ...
  • The Impact of COVID-19-Induced Changes at Schools on Elementary Students' School Engagement 

    Thorsteinsen, Kjærsti; Parks-Stamm, Elizabeth J.; Olsen, Marte; Kvalø, Marie; Martiny, Sarah E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-09)
    In spring 2020, the COVID-19 pandemic led to the shutdown of schools in many countries. Emerging research documents the negative effects of the pandemic and particularly of the shutdown of schools on children's well-being.

  • Altered functional connectivity in adolescent anorexia nervosa is related to age and cortical thickness 

    Myrvang, Anna Dahl; Vangberg, Torgil R.; Linnman, Clas; Stedal, Kristin; Rø, Øyvind; Endestad, Tor; Rosenvinge, Jan H.; Aslaksen, Per M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-06)
    Introduction - Functional networks develop throughout adolescence when anorexia nervosa (AN) normally debuts. In AN, cerebral structural alterations are found in most brain regions and may be related to the observed functional brain changes. Few studies have investigated the functional networks of the brain in adolescent AN patients.. The aim of this explorative study was to investigate multiple ...
  • The hers and his of prosociality across 10 countries 

    Olsson, Maria; Froehlich, Laura; Dorrough, Angela R.; Martiny, Sarah E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-19)
    Is there a ‘more helpful’ gender? The present research assessed gender differences in prosocial self-perceptions, prosocial behavioural intentions, and prosocial (transfer) behaviour in same- and other-gender interactions in 10 countries (N = 1,915). The present results showed negligible differences in the degree to which women and men saw themselves as prosocial. However, larger gender differences ...
  • Transcranial Direct Current Stimulation above the Medial Prefrontal Cortex Facilitates Decision-Making following Periods of Low Outcome Controllability 

    Csifcsak, Gabor; Bjørkøy, Jorunn; Kuyateh, Sarjo; Reithe, Haakon; Mittner, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-25)
    Recent studies suggest that choice behavior in reinforcement learning tasks is shaped by the level of outcome controllability. In particular, Pavlovian bias (PB) seems to be enhanced under low levels of control, manifesting in approach tendencies toward rewards and response inhibition when facing potential losses. The medial prefrontal cortex (mPFC) has been implicated both in evaluating outcome ...
  • A two-lab direct replication attempt of Southgate, Senju and Csibra (2007) 

    Kampis, D.; Kármán, P.; Csibra, G.; Southgate, V.; Hernik, M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-25)
    The study by Southgate et al. (2007 Psychol. Sci.18, 587–592. (doi:10.1111/j.1467-9280.2007.01944.x)) has been widely cited as evidence for false-belief attribution in young children. Recent replication attempts of this paradigm have yielded mixed results: several studies did not replicate the original findings, raising doubts about the suitability of the paradigm to assess non-verbal action prediction ...

    <i>Background</i> - As epidemiological data on child mental health in low- and middle-income countries are limited, a large-scale survey was undertaken to estimate the prevalence and amount of child emotional and behavioral problems (EBP) in Nepal as reported by the parents.<br><br> <i>Methods</i> - 3820 schoolchildren aged 6–18 years were selected from 16 districts of the three geographical ...
  • Emotional Infant Face Processing in Women With Major Depression and Expecting Parents With Depressive Symptoms 

    Bohne, Agnes; Nordahl, Dag; Lindahl, Åsne; Ulvenes, Pål Gunnar; Wang, Catharina Elisabeth Arfwedson; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-02)
    Processing of emotional facial expressions is of great importance in interpersonal relationships. Aberrant engagement with facial expressions, particularly an engagement with sad faces, loss of engagement with happy faces, and enhanced memory of sadness has been found in depression. Since most studies used adult faces, we here examined if such biases also occur in processing of infant faces in those ...
  • Koronapandemien gjorde babyforskning ved UiT lettere 

    Thale, Tøllefsen; Flatebø, Solveig (Journal article; Tidsskriftartikkel, 2021-02-05)
