    Understanding how people rate their confidence is critical for the characterization of a wide range of perceptual, memory, motor and cognitive processes. To enable the continued exploration of these processes, we created a large database of confidence studies spanning a broad set of paradigms, participant populations and fields of study. The data from each study are structured in a common, easy-to-use ...
  • Acquiring sub-efficient and efficient variants of novel means by integrating information from multiple social models in preschoolers 

    Altınok, Nazlı; Hernik, Mikołaj; Király, Ildikó; Gergely, György (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-08)
    Sub-efficient action routines often represent culture-specific conventional forms of actions that belong to the repertoire of cultural knowledge shared by a social group. Children readily acquire such sub-efficient routines from social demonstrations and often preserve them in their action repertoire despite encountering more efficient alternatives. This suggests that they can treat sub-efficient ...
  • Predictive and diagnostic utility of brief neuropsychological assessment in detecting Alzheimer's pathology and progression to dementia 

    Eliassen, Ingvild Vøllo; Fladby, Tormod; Kirsebom, Bjørn-Eivind; Waterloo, Knut; Eckerström, Marie; Wallin, Anders; Bråthen, Geir; Aarsland, Dag; Hessen, Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
    Objective: To assess the role of brief neuropsychological assessments in prediction and identification of Alzheimer’s disease (AD) pathology and progression to AD dementia. Method: Adults (N = 255; range = 40–81 years) with self-reported cognitive decline underwent baseline and 2-year follow-up clinical assessment, including a brief neuropsychological screening and lumbar puncture. Five different ...
  • Sleep patterns and insomnia in a large population-based study of middle-aged and older adults: The Tromsø study 2015–2016 

    Sivertsen, Børge; Pallesen, Ståle; Friborg, Oddgeir; Nilsen, Kristian Bernhard; Bakke, Øystein; Goll, Jonas Bjørnskov; Hopstock, Laila Arnesdatter (Journal article; Tidsskriftartikkel, 2020-05-29)
    Epidemiological studies assessing adult sleep duration have yielded inconsistent findings and there are still large variations in estimation of insomnia prevalence according to the most recent diagnostic criteria. Our objective was to describe sleep patterns in a large population of middle‐aged and older adults, by employing accurate measures of both sleep duration and insomnia. Data stem from the ...
  • 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. ...
  • Girls’ perceptions of their mothers at work and home: Warm does not mean weak 

    Parks-Stamm, Elizabeth J.; Henson, Emma; Martiny, Sarah E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-11)
    Upper elementary school girls were surveyed about their mothers’ and fathers’ warmth, competence, and agency at home and how they imagine their parents at work. Mothers’ warmth at home was positively correlated with perceived competence and agency both at home and at work. Differences between daughters’ perceptions of their mothers and fathers at work are discussed.
  • Human tool cognition relies on teleology 

    Hernik, Mikołaj (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-10)
    Osiurak and Reynaud's account of human tool cognition misses key element: human capacity for functional representations and teleological inferences. I argue that the teleofunctional approach accounts better for some features of human tool cognition and points to a viable candidate for the cognitive “difference-maker” behind human technological success.
  • Allmennlegers erfaringer med spiseforstyrrelser 

    Aalmen, Mia Holtet; Rosenvinge, Jan H; Holund, Andreas; Pettersen, Gunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-15)
    <i>BAKGRUNN</i> - Allmennlegen spiller en nøkkelrolle i å utrede, diagnostisere og behandle spiseforstyrrelser. Denne rollen utfordres av kliniske særtrekk ved pasientgruppen, legenes arbeidshverdag og samarbeidsforhold med spesialisthelsetjenesten. Hensikten med denne studien var å få mer kunnskap om hvordan allmennleger møter slike utfordringer.<p> <p><i>MATERIALE OG METODE</i> - Fem allmennleger ...
  • Silencing and stimulating the medial amygdala impairs ejaculation but not sexual incentive motivation in male rats 

    Huijgens, Patty; Heijkoop, Roy; Snoeren, Eelke (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-24)
    The medial amygdala (MeA) is a sexually dimorphic brain region that integrates sensory information and hormonal signaling, and is involved in the regulation of social behaviors. Lesion studies have shown a role for the MeA in copulation, most prominently in the promotion of ejaculation. The role of the MeA in sexual motivation, but also in temporal patterning of copulation, has not been extensively ...
  • How study environments foster academic procrastination: Overview and recommendations 

    Svartdal, Frode; Dahl, Tove I.; Gamst-Klaussen, Thor; Koppenborg, Markus; Klingsieck, Katrin (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-02)
    Procrastination is common among students, with prevalence estimates double or even triple those of the working population. This inflated prevalence indicates that the academic environment may appear as “procrastination friendly” to students. In the present paper, we identify social, cultural, organizational, and contextual factors that may foster or facilitate procrastination (such as large degree ...
  • Daily associations between sleep and pain in patients with chronic musculoskeletal pain 

    Abeler, Karin; Bergvik, Svein; Sand, Trond; Friborg, Oddgeir (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-02)
    Patients with chronic pain commonly report sleep problems, and the evidence for a relationship between sleep disturbance and pain seems robust. The day‐to‐day associations between these constructs are less well studied, particularly with objective sleep measures such as actigraphy. Moreover, the concurrent presence of negative affective symptoms, as well as seasonality effects at extreme latitudes ...
  • Sleep Characteristics in Adults With and Without Chronic Musculoskeletal Pain. The Role of Mental Distress and Pain Catastrophizing 

    Abeler, Karin; Friborg, Oddgeir; Engstrøm, Morten; Sand, Trond; Bergvik, Svein (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-15)
    <p>Objectives: Sleep disturbance is associated with persistence and exacerbation of chronic pain. As this relationship seems to be bidirectional, factors underpinning sleep disturbance may prove important in multimodal rehabilitation approaches. The aim of this cross-sectional study was to examine the impact of psychological symptoms on subjective and objective sleep measures in patients with chronic ...
  • Seasonality in pain, sleep and mental distress in patients with chronic musculoskeletal pain at latitude 69° N 

    Abeler, Karin; Sand, Trond; Friborg, Oddgeir; Bergvik, Svein (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-28)
    Seasonality is evident in several aspects of human health and behavior, whereas seasonality in chronic pain is less well studied. We examined seasonal variation in pain severity and pain dissemination, as well as in pain-associated conditions, such as sleep impairment, sleep timing, mental distress, fatigue and physical activity. We also examined if any of these associated conditions moderated the ...
  • Sleep in the land of the midnight sun and polar night: The Tromsø study 

    Sivertsen, Børge; Friborg, Oddgeir; Pallesen, Ståle; Vedaa, Øystein; Hopstock, Laila Arnesdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-29)
    While some diseases and human behaviors fluctuate consistently with season, the extent of seasonal variations in sleep, especially at high latitudes, is less consistent. We used data from a geographic region (69º North) with extremely large seasonal differences in daylight that had the participants blinded for the current study’s hypotheses. Data were derived from the Tromsø Study (2015–2016), an ...
  • The interplay between executive control, behavioral variability and mind wandering: Insights from a high-definition transcranial direct-current stimulation study 

    Boayue, Nya Mehnwolo; Csifcsak, Gabor; Kreis, Isabel Viola; Schmidt, Carole; Finn, Iselin Caroline; Vollsund, Anna Elfrida Hovde; Mittner, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-21)
    While the involvement of executive processes in mind wandering is largely undebated, their exact relationship is subject to an ongoing debate and rarely studied dynamically within‐subject. Several brain‐stimulation studies using transcranial direct current stimulation (tDCS) have attempted to modulate mind‐wandering propensity by stimulating the left dorsolateral prefrontal cortex (DLPFC) which is ...
  • Rapid changes in sociosexual behaviors around transition to and from behavioral estrus, in female rats housed in a seminatural environment 

    Le Moene, Olivia; Hernandez-Arteaga, Enrique; Chu, Xi; Ågmo, Anders (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-28)
    Gonadally intact female rats display sexual behaviors only during a portion of the estrus cycle. In standard experimental setups, the on- and offset of sexual behavior is gradual. However, in naturalistic settings, it is almost instantaneous. We assessed the changes in sociosexual behaviors at the beginning and end of behavioral estrus in ovariectomized females treated with ovarian hormones. Rats ...
  • Winter is coming: Wintertime mindset and wellbeing in Norway 

    Leibowitz, Kari; Vittersø, Joar (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-30)
    Previous research of the effect of winter on wellbeing has yielded contradictory findings. While there is evidence that the lack of sunlight in wintertime can lead to seasonal depression and negative emotions, many individuals are able to thrive during the winter. What might determine whether the darkness of winter leads to poor psychological outcomes? To investigate whether or not mindset contributes ...
  • Effects of dichotic listening on gait domains of healthy older adults during dual-tasking: An exploratory observational study 

    Castro-Chavira, Susana Angelica; Gorecka, Marta Maria; Vasylenko, Olena; Rodriguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-28)
    <i>Background</i> - Identification of the cognitive mechanisms behind gait changes in aging is a prime endeavor in gerontology and geriatrics. For this reason, we have implemented a new dual-task paradigm where an auditory attentional task is performed during over-ground walking. Dichotic listening assesses spontaneous attention and voluntary attention directed to right and left-ear. The uniqueness ...
  • Deliberation Decreases the Likelihood of Expressing Dominant Responses 

    Martiny-Huenger, Torsten; Bieleke, Maik; Doerflinger, Johannes T.; Stephensen, Matthew; Gollwitzer, Peter M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-11)
    Deliberation is commonly assumed to be a central characteristic of humans’ higher cognitive functions, and the responses following deliberation are attributed to mechanisms that are qualitatively different from lower-level associative or affectively driven responses. In contrast to this perspective, the current article’s aim is to draw attention to potential issues with making inferences about ...
  • Effects of gonadectomy and dihydrotestosterone on neuronal plasticity in motivation and reward related brain regions in the male rat 

    Huijgens, Patty; Snoeren, Eelke; Meisel, Robert; Mermelstein, Paul (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-06)
    Gonadal hormones affect neuronal morphology to ultimately regulate behaviour. In female rats, oestradiol mediates spine plasticity in hypothalamic and limbic brain structures, contributing to long‐lasting effects on motivated behaviour. Parallel effects of androgens in male rats have not been extensively studied. Here, we investigated the effect of both castration and androgen replacement on spine ...
