  • 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 ...

    Ma, Jasmine; Mahat, Pashupati; Brøndbo, Per Håkan; Handegård, Bjørn H.; Kvernmo, Siv; Javo, Anne Cecilie (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-03)
    <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 ...

  • Male rat sexual behavior: Insights from inter-copulatory intervals 

    Huijgens, Patty Thalia; Guarraci, Fay; Olivier, Jocelien; Snoeren, Eelke (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-09)
    The assessment of sexual behavior in male rats with the aim of unraveling underlying neurobiological mechanisms has in the recent decades been reduced to the annotation of mounts, intromissions and ejaculations. To provide a better understanding of the structure and patterns of copulation, it is necessary to extend and tailor the analysis to the natural organization of male rat copulation. This will ...
  • Childhood Sensorineural Hearing Loss and Divorce in a Large Norwegian Cohort: Results from the HUNT Study

  • Faktorer som henger sammen med ungdommers fordommer mot temaet psykisk helse 

    Wollmann, Brita (Master thesis; Mastergradsoppgave, 2019-08-01)
    Hovedoppgaven var en del av et større forskningsprosjekt i regi av professorene Ingunn Skre og Rannveig Grøm Sæle. Tidligere studier har forsøkt å kartlegge faktorer som henger sammen med å ha fordommer mot temaet psykisk helse hos ungdom. Kjønn og alder har vist seg å være av betydning, da å være yngre og å være gutt henger sammen mer fordommer mot temaet. Det finnes imidlertid ikke nok studier til ...
  • The Effects of Perinatal Fluoxetine Exposure on Social and Non-Social Investigation Behaviors in a Novel Environment 

    Johansen, Jesper Solheim; Sylte, Ole Christian (Mastergradsoppgave; Master thesis, 2020-07-31)
    Selective serotonin reuptake inhibitors (SSRIs) are increasingly prescribed as medication for various affective disorders during pregnancy. SSRIs cross the placenta and affect serotonergic neurotransmission in the fetus, but the neurobehavioral consequences for the offspring remain largely unclear. Recent research has linked perinatal SSRI exposure to alterations in both social and non-social ...
  • Flow in Physical Activity and Exercise: Exploring the Relevance of Mindfulness and Exertion 

    Karlsen, Karoline (Master thesis; Mastergradsoppgave, 2021-05-14)
    Experiencing flow in physical activity is associated with intrinsic motivation and has proven to be a highly rewarding state of mind (Csikszentmihalyi, 2008). Facilitating flow experiences among regular exercisers can be beneficial in terms of promoting long-term physical activity engagement. In a longitudinal study we explored possible factors predicting flow experiences in exercisers by measuring ...
  • The help may be far away: The effect of construal level and social distance on charity donations 

    Høgsdal, Helene (Master thesis; Mastergradsoppgave, 2021-05-17)
    Is it possible to influence people´s willingness to donate money? In two experiments we investigated whether participant´s (N = 417) willingness to donate money to a charitable cause could be influenced by mental representations and social distance towards the donation target. In both experiments we manipulated the perceived social distance towards the donation target, and the construal level of the ...

  • Working for the Best or Bracing for the Worst? Approach and Avoidance Motivation in Planning 

    Bø, Simen; Sjåstad, Hallgeir; Norman, Elisabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-11)
    Even though planning is generally helpful in goal pursuit, people do not always choose to plan. The inclination to plan might depend on whether we focus on what we seek to approach or what we seek to avoid. In two pre-registered experiments, we tested the relative effect of approach versus avoidance motivation on willingness to plan (total <i>N</i>=1349). With outcome framing as the experimental ...
  • Distracting stimuli evoke ventral tegmental area responses in rats during ongoing saccharin consumption 

    Peters, Kate Z.; Young, Andrew M J; McCutcheon, James Edgar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-11)
    Disruptions in attention, salience and increased distractibility are implicated in multiple psychiatric conditions. The ventral tegmental area (VTA) is a potential site for converging information about external stimuli and internal states to be integrated and guide adaptive behaviours. Given the dual role of dopamine signals in both driving ongoing behaviours (e.g., feeding) and monitoring salient ...
  • Resonance frequency is not always stable over time and could be related to the inter‑beat interval 

    Capdevila, Lluis; Parrado, Eva; Ramos-Castro, Juan; Zapata-Lamana, Rafael; Lalanza, Jaume F (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-16)
    Heart Rate Variability Biofeedback (HRVB) is based on breathing at an optimal rate (or resonance frequency, RF) corresponding to the respiratory sinus arrhythmia (RSA). Our aim is to check whether the RF is a stable factor and analyse the HRV parameters individually per each breathing rate, comparing it with free slow breathing. A sample of 21 participants were trained in a test–retest HRVB ...
  • Rat ultrasonic vocalizations and novelty-induced social and non-social investigation behavior in a seminatural environment 

    Heinla, Indrek; Chu, Xi; Ågmo, Anders j; Snoeren, Eelke (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-03)
    Although rats are known to emit ultrasonic vocalizations (USVs), it remains unclear whether these calls serve an auditory communication purpose. For USVs to be part of communication, the vocal signals will need to be a transfer of information between two or more conspecifics, and with the possibility to induce changes in the behavior of the recipient. Therefore, the aim of our study was to investigate ...
  • Sexual incentive motivation and male and female copulatory behavior in female rats given androgen from postnatal day 20 

    Chu, Xi; Snoeren, Eelke; Södersten, Per; Ågmo, Anders j (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-12)
    Masculinization and feminization of rat sexual behavior has been supposed to occur during a short postnatal period. However, much data have made it evident that these processes may continue until adolescence. In the present study, we evaluated whether androgen treatment of females from postnatal day 20 and onwards could alter sexual motivation and behavior in a male direction. Juveniles were ...
