    The present work investigates the endorsement, antecedents, relationships, and consequences of young immigrants’ social identities in Norway. Despite increasing numbers of refugees and immigrants entering Norway in recent years, little is known about the relationship between immigrants’ different social identities and their feeling of integration into Norwegian society. The main goal of the present ...
  • The role of adrenoceptors in the central nervous system in male and female rat sexual behavior 

    Snoeren, Eelke (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2014-09-10)
    Three different phases can be distinguished in rats’ sexual cycle, the introductory (precopulatory), the copulatory and the executive (ejaculatory) phases. In this review, a new analysis of existing pharmacological data is made, both in male and female rats, in which the different aspects of sexual behavior are taken into account. An effort is made to distinguish pharmacological effects on sexual ...
  • Functions of Vocalization in Sociosexual Behaviors in Rats (Rattus norvegicus) in a Seminatural Environment 

    Chu, Xi; Snoeren, Eelke; Ågmo, Anders j (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2017-01-09)
    Both male and female rats produce vocalizations in the presence of a potential sexual partner. In this study, we evaluated the role of vocalizations in sociosexual behaviors in an ecologically valid procedure. Three males and 4 females were housed in a seminatural environment. In each group, 1 or 2 males and females were devocalized, and the other subjects were sham operated. Sociosexual interactions ...

    Øvervoll, Morten; Schettino, Ilaria; Suzuki, Hikaru; Okubo, Matia; Laeng, Bruno (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-14)
    Images of European female and male faces were digitally processed to generate spatial frequency (SF) filtered images containing only a narrow band of visual information within the Fourier spectrum. The original unfiltered images and four SF filtered images (low, medium-low, medium-high and high) were then paired in trials that kept constant SF band and face gender and participants made a forced-choice ...
  • Responses to positive and aversive stimuli in estrous female rats housed in a seminatural environment: Effects of yohimbine and chlordiazepoxide 

    Le Moëne, Olivia; Ågmo, Anders j (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-05)
    The behavioral effects of putative anxiolytic and anxiogenic drugs are usually evaluated in highly standardized tests. Here, we determined the effects of such drugs in rats housed in mixed sex groups in a seminatural environment. Sexually receptive female Wistar rats were treated with either the anxiolytic drug chlordiazepoxide (2 mg/kg), the anxiogenic drug yohimbine (1 mg/kg), or saline (1 ml/kg). ...
  • Measuring implemental delay in procrastination: Separating onset and sustained goal striving 

    Svartdal, Frode; Klingsieck, Katrin; Steel, Piers; Gamst-Klaussen, Thor (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-13)
    Scales measuring procrastination focus on different aspects of unnecessary and unwanted delay, delay in task implementation – an increased gap between intention and action – being a core characteristic. However, an inspection of existing procrastination scales reveals that the scales do not distinguish between two facets of implemental delay, <i>onset delay</i>, and delay related to <i>sustained ...
  • White matter correlates of gait perturbations resulting from spontaneous and lateralized attention in healthy older adults: A dual-task study 

    Castro Chavira, Susana Angelica; Vangberg, Torgil Riise; Gorecka, Marta Maria; Vasylenko, Olena; Waterloo, Knut; Rodriguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-18)
    To date the neural mechanisms behind gait perturbations caused by dual-task paradigms are still unknown. Therefore, the present study examined white matter correlates of gait perturbations caused by a dichotic listening task where spontaneous (free focus of attention) and lateralized attentional control (voluntary attention directed to right or left-ear) were tested. Fifty-nine right-handed, healthy ...

    <i>Objectives</i> - Positive embodiment and healthy lifestyle habits seem to be related; therefore, stimulating positive embodiment should promote healthy lifestyle habits. In the current study, we delivered the Healthy Body Image (HBI) intervention among Norwegian high school students and examined the effects on healthy lifestyle habits.<p> <p><i>Methods</i> - The HBI intervention comprises three ...
  • Now you see it, now you don’t: Solid and subtle differences between Hedonic and Eudaimonic Wellbeing 

    Thorsteinsen, Kjærsti; Vittersø, Joar (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-10)
    Data from an intensive longitudinal goal intervention study in Norway (N = 138) were used to test the assumption that hedonic (HWB) and eudaimonic (EWB) wellbeing reflect two distinct dimensions of wellbeing. Based on multilevel factor analyses, a path model and hierarchical regression analyses the paper aimed to demonstrate that a basic duality between the two kinds of wellbeing exists. Compared ...
  • Measuring Resilience Across Australia and Norway: Validation and Psychometric Properties of the English Version of the Resilience Scale for Adults. 

    Anyan, Frederick; Hjemdal, Odin; Bizumic, Boris; Friborg, Oddgeir (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2019-04-05)
    Resilience has become increasingly important in clinical and health psychology, but only few scales have received good psychometric ratings for assessing various outcomes of resilience. The Resilience Scale for Adults (RSA) is one of the best psychometrically rated scales and has been validated among Norwegian samples. The purpose of this study was to explore the construct validity of the RSA in an ...
  • Modeling Human Sexual Motivation in Rodents: Some Caveats 

    Le Moëne, Olivia; Ågmo, Anders j (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-27)
    Sexual behavior is activated by motivation. An overwhelming majority of experimental studies of the intricacies of sexual motivation has been performed in rodents, most of them in rats. Sometimes it is desirable to generalize results obtained in this species to other species, particularly the human. It is hoped that studies of the neurobiology of rodent sexual behavior may shed light on the central ...

    Hessen, Erik; Kirsebom, Bjørn-Eivind; Eriksson, Cecilia Magdalena; Eliassen, Carl Fredrik Andestad; Nakling, Arne; Bråthen, Geir; Waterloo, Knut; Aarsland, Dag; Fladby, Tormod (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-22)
    <i>Background:</i> In the care of persons with cognitive problems, it is important to use a valid mild cognitive impairment (MCI) criterion that discriminates well between normal and pathological aging.<p> <p><i>Objective:</i> To find the brief neuropsychological screening criterion that best correlates with cerebrospinal fluid (CSF) biomarkers for cognitive decline and dementia in persons ...
  • Metacognition in psychology 

    Norman, Elisabeth; Pfuhl, Gerit; Sæle, Rannveig Grøm; Svartdal, Frode; Låg, Torstein; Dahl, Tove Irene (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-25)
    How has the concept of metacognition been used within basic and applied psychological research? We begin our answer by presenting a broad definition of metacognition, a historical overview of its development and its presence in research databases. To assess which function and facets are most frequently addressed within each of the sub-disciplines, we present results from separate literature searches. ...
  • Attitudes Towards the Use of Routine Outcome Monitoring of Psychological Therapies Among Mental Health Providers: The EBPAS–ROM 

    Rye, Marte; Rognmo, Kamilla; Aarons, Gregory A.; Skre, Ingunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-28)
    Implementation of routine outcome monitoring (ROM) in mental health care is progressing slowly. Knowledge about factors influencing ROM implementation, including health providers’ attitudes towards ROM, is necessary. Based on a survey of 662 psychologists and nurses, this article describes (1) the development of a short instrument measuring provider attitudes towards ROM, derived from the Evidence-based ...
  • A novel experimental paradigm with improved ecological validity reveals robust action-associated enhancement of the N1 visual event-related potential in healthy adults 

    Balla, Viktória Roxána; Szalóki, Szilvia; Kilencz, Tünde; Dalos, Vera Daniella; Németh, Roland; Csifcsak, Gabor (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-11)
    The association between an action and its sensory consequence has been linked to our sense of agency (SoA). While ecological validity is crucial in investigating such a complex phenomenon, previous paradigms focusing on the cortical analysis of movement-related images used simplified experimental protocols. Here, we examined the influence of action-associated predictive processes on visual event-related ...
  • Internalizing problems and attentional control: Effects on cardiac autonomic responses after the induction of negative affect 

    Andersen, Tonje Grønning; Fiskum, Charlotte; Aslaksen, Per M; Flaten, Magne Arve; Jacobsen, Karl Henry (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
    Individuals with internalizing problems differ in levels of attentional control (AC), and this heterogeneity could be associated with differences in autonomic arousal. The present study investigated whether AC moderated the effect of internalizing problems on self-reported experience and autonomic nervous system (ANS) responses after the induction of negative affect. Children aged 9–13 years were ...
  • Increasing propensity to mind‐wander by transcranial direct current stimulation? A registered report 

    Boayue, Nya Mehnwolo; Csifcsak, Gabor; Aslaksen, Per M; Turi, Zsolt; Antal, Andrea; Groot, Josephine Maria; Hawkins, Guy E.; Forstmann, Birte U.; Opitz, Alexander; Thielscher, Axel; Mittner, Matthias (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2019-01-24)
    Transcranial direct current stimulation (tDCS) has been proposed to be able to modulate different cognitive functions. However, recent meta‐analyses conclude that its efficacy is still in question. Recently, an increase in subjects’ propensity to mind‐wander has been reported as a consequence of anodal stimulation of the left dorsolateral prefrontal cortex (Axelrod et al., Proceedings of the National ...
  • Mild Effect of Nalmefene on Alcoholic Cue-Induced Response Invigoration in Alcohol Use Disorder Without Accompanying Changes in Electrophysiological Signatures of Early Visual Processing and Executive Control 

    Gál, Bernadett Ildikó; Kilencz, Tunde; Albert, Anita; Demeter, Ildikó; Hegedűs, Klára Mária; Janka, Zoltán; Csifcsak, Gabor; Álmos, Péter Zoltán (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-26)
    Nalmefene is approved for as-needed pharmacological treatment in alcohol use disorder (AUD) by the European Medicines Agency. While the cellular effects of nalmefene have been thoroughly investigated, data are very limited on how this agent influences neural signals associated with inhibitory control and the visual analysis of environmental cues. This double-blind crossover study assessed the ...
  • Profiles of Perfectionism Among Adolescents Attending Specialized Elite- and Ordinary Lower Secondary Schools: A Norwegian Cross-Sectional Comparative Study 

    Stornæs, Annett Victoria; Rosenvinge, Jan H; Sundgot-Borgen, Jorunn; Pettersen, Gunn; Friborg, Oddgeir (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-06)
    The versatile construct of perfectionism has been heavily debated, e.g., its nature or measurement constituents, how it influences performances or, most importantly, our health. Conventional linear analyses seem inadequate to address such challenges. Hence, we used a latent variable and a person-centered approach to identify different patterns of perfectionism, and their relationships with psychological ...
