    • Evidence for Cognitive Placebo and Nocebo Effects in Healthy Individuals 

      Turi, Z; Bjørkedal, Espen; Gunkel, Luisa; Antal, Andrea; Paulus, Walter; Mittner, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-28)
      Inactive interventions can have significant effects on cognitive performance. Understanding the generation of these cognitive placebo/nocebo effects is crucial for evaluating the cognitive impacts of interventional methods, such as non-invasive brain stimulation (NIBS). We report both cognitive placebo and nocebo effects on reward-based learning performance induced using an active sham NIBS protocol, ...
    • The Evidence-based Practice Attitude Scale- 36 (EBPAS-36): a brief and pragmatic measure of attitudes to evidence-based practice validated in US and Norwegian samples 

      Rye, Marte; Torres, E.M; Friborg, Oddgeir; Aarons, Gregory A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
      Background: Short and valid instruments for measuring factors facilitating or hindering implementation efforts are called for. This article describes (1) the adaptation of a shorter version of the Evidence-based Practice Attitude Scale (EBPAS-50 items), and (2) the psychometric properties of the shortened version in both US and Norwegian data. <p> Methods: The US participants were mental health ...
    • Examining Procrastination across Multiple Goal Stages: A Longitudinal Study of Temporal Motivation Theory 

      Steel, Piers; Svartdal, Frode; Thundiyi, T.; Brothen, T. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-03)
      Procrastination is among the most common of motivational failures, putting off despite expecting to be worse off. We examine this dynamic phenomenon in a detailed and realistic longitudinal design (Study 1) as well as in a large correlational data set (N = 7400; Study 2). The results are largely consistent with temporal motivation theory. People’s pacing style reflects a hyperbolic curve, with the ...
    • Expectations of increased and decreased pain explain the effect of conditioned pain modulation in females 

      Bjørkedal, Espen; Flaten, Magne Arve (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Chronic pain is believed to be related to a dysfunction of descending pain modulatory mechanisms. Functioning of descending pain modulation can be assessed by various methods, including conditioned pain modulation (CPM). CPM refers to the inhibition of one source of pain by a second noxious stimulus, termed the conditioning stimulus. This procedure can activate an endogenous pain inhibitory mechanism ...
    • Experiences matter: Positive emotions facilitate intrinsic motivation 

      Løvoll, Helga Synnevåg; Røysamb, Espen; Vittersø, Joar (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-26)
      This paper has two major aims. First, to investigate how positive emotions and intrinsic motivation affect each other over time. Second, to test the effect of positive emotions and intrinsic motivation on subsequent educational choices. Through two ordinary study semesters, 64 sport students in Norway reported on their intrinsic motivation for outdoor activities (twice) as well as positive ...
    • Exploration of plasma lipids in mild cognitive impairment due to Alzheimer's disease 

      Bergland, Anne Katrine; Proitsi, Petroula; Kirsebom, Bjørn-Eivind; Sønnesyn, Hogne; Hye, Abdul; Larsen, Alf Inge; Xu, Jin; Legido-Quigley, Cristina; Rajendran, Lawrence; Fladby, Tormod; Aarsland, Dag (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-29)
      <p><i>Background: </i>Lipids have important structural roles in cell membranes and changes to these membrane lipids may influence β- and γ-secretase activities and thus contribute to Alzheimer’s disease (AD) pathology. <p><i>Objective:</i> To explore baseline plasma lipid profiling in participants with mild cognitive impairment (MCI) with and without AD pathology. <p><i>Methods: </i>We identified ...

      Flores, Lizbett; Ytterstad, Elinor; Lensing, Michael B.; Eisemann, Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
      <p><i>Objective</i>: To explore personality and readiness to change among substance use disorders (SUD) patients with and without ADHD.</p> <p><i>Method</i>: SUD + ADHD versus SUD − ADHD patients consecutively entering treatment between 2010 and 2012 were compared concerning personality (Temperament and Character Inventory) and readiness to change (Stages of Change Readiness and Treatment Eagerness ...
    • Exploring the determinants of reinvestment decisions: Sense of personal responsibility, preferences, and loss framing 

      Doerflinger, Johannes T.; Martiny-Huenger, Torsten; Gollwitzer, Peter M. (Journal article; Tidsskriftartikkel, 2023-01-12)
      Two potentially costly errors are common in sequential investment decisions: sticking too long to a failing course of action (escalation of commitment), and abandoning a successful course of action prematurely. Past research has mostly focused on escalation of commitment, and identified three critical determinants: personal responsibility, preferences for prior decisions, and decision framing. We ...
    • EXPRESS: The retention of proprioceptive information is suppressed by competing verbal and spatial task 

      Rago, Anett; Horvath, Aron (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-11)
      Proprioceptive information makes us able to perceive the position of our joints from an internal point of view. In certain cases, proprioceptive information has to be stored in short-term memory, for example, during the learning of new motor skills or the assessment of proprioceptive accuracy. However, there are contradictory findings about the modality-specific storage of proprioceptive information ...
    • The factor structure and psychometric properties of the Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE-OM) in Norwegian clinical and non-clinical samples 

      Skre, Ingunn; Friborg, Oddgeir; Elgarøy, Sigmund; Evans, Chris; Myklebust, Lars Henrik Ryther; Lillevoll, Kjersti; Sørgaard, Knut; Hansen, Vidje (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Background The Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM) is a 34-item instrument developed to monitor clinically significant change in out-patients. The CORE-OM covers four domains: well-being, problems/symptoms, functioning and risk, and sums up in two total scores: the mean of All items, and the mean of All non-risk items. The aim of this study was to examine the ...
    • Failure to Find a Conditioned Placebo Analgesic Response 

      Flaten, Magne; Bjørkedal, Espen; Lyby, Peter Solvoll; Figenschau, Yngve Anton; Aslaksen, Per M (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-30)
      <p><i>Background</i>: Associative learning has, in several studies, been modulated by the sex of the participant. Consistent with this, a recent review found that conditioned nocebo effects are stronger in females than in males.</p> <p><i>Purpose</i>: It has been suggested that conditioned placebo responses are stronger in females, and this hypothesis was investigated in the present study. Cortisol ...
    • Fear of diseases among people over 50 years of age : a survey 

      Bystad, Martin Kragnes; Grønli, Ole Kristian; Lilleeggen, Camilla; Aslaksen, Per M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-12-11)
      The aim of this study was to investigate the association between well-known diseases and fear of them in individuals over 50 years of age. Information on the fear of diseases can be relevant for both public health information purposes and clinical setting diagnostics. However, very few studies have investigated the fear of diseases in individuals over the age of 50. We used an electronic survey ...
    • Fear of pain potentiates nocebo hyperalgesia 

      Aslaksen, Per M.; Lyby, Peter Solvoll (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-10-12)
      Nocebo hyperalgesia has received sparse experimental attention compared to placebo analgesia. The aim of the present study was to investigate if personality traits and fear of pain could predict experimental nocebo hyperalgesia. One hundred and eleven healthy volunteers (76 females) participated in an experimental study in which personality traits and fear of pain were measured prior to induction ...
    • The Fear of Pain Questionnaire-III and the Fear of Pain Questionnaire-Short Form: a confirmatory factor analysis 

      Vambheim, Sara Magelssen; Lyby, Peter Solvoll; Aslaksen, Per M.; Flaten, Magne; Åsli, Ole; Martinussen, Laila Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-08)
      <i>Background</i>: The Fear of Pain Questionnaire-III (FPQ-III) is a widely used instrument to assess the fear of pain (FOP) in clinical and nonclinical samples. The FPQ-III has 30 items and is divided into three subscales: Severe Pain, Minor Pain and Medical Pain. Due to findings of poor fit of the original three-factor FPQ-III model, the Fear of Pain Questionnaire-Short Form ...
    • Feeling and Thinking about It Are Two Different Things: How to Capture Momentary Emotions of Extreme Sports in the Field 

      Hetland, Audun (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-24)
      To learn about extreme sports and what motivates such activities, we need to understand the emotions embedded in the experience itself. However, how we go about assessing these emotions might provide us with very different answers. An experience is a fleeting and ever-changing phenomenon, rich in detail and filled with nuances. What we remember and, therefore, what we are able to report from our ...
    • Feeling out of place: Internalized age stereotypes are associated with older employees’ sense of belonging and social motivation. 

      Rahn, Georg; Martiny, Sarah E.; Nikitin, Jana (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-05)
      Older employees are not only confronted with subtle negative stereotypes about cognitive decline, but they also tend to internalize these negative stereotypes (i.e., they agree with the idea that intellectual performance declines in old age and they feel affected by this decline). Previous research has shown that internalizing negative age stereotypes has detrimental effects on work-related outcomes. ...
    • Female rat sexual behavior is unaffected by perinatal fluoxetine exposure 

      Hegstad, Jan; Huijgens, Patty Thalia; 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 ...
    • Female Reproductive Behavior 

      Snoeren, Eelke (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-19)
    • Field Notes from the Quest for the First use of Acculturation 

      Rudmin, Floyd Webster (Journal article; Tidsskriftartikkel, 2003)
      Quest begin in the vauge way, as an interest or an orientation, and maybe as a collection of skills. I was probably bent towards this quest at Queen's University, where I was mentored in cross-cultural psychology by John Berry, where I served as a TA in Milt Suboski's statistics and research methods courses, and where I learned the lore of history of psychology with David Murray. Quests often begin ...
    • Filtered beauty in Oslo and Tokyo: A spatial frequency analysis of facial attractiveness 

      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 ...
