  • Perinatal fluoxetine exposure changes social and stress-coping behavior in adult rats housed in a seminatural environment 

    Houwing, Danielle; Heijkoop, Roy; Olivier, Jocelien; Snoeren, Eelke (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-06)
    The use of selective serotonin reuptake inhibitors (SSRI) during pregnancy has increased tremendously, but the consequences for the offspring remain largely unclear. Several studies have described potential effects of perinatal SSRI-exposure on neurobehavioral outcomes using simplified rodent test set-ups, however these set-ups only assess a small fraction of the behavior. For translational purposes ...
  • Procrastination and personal finances: Exploring the roles of planning and financial self-efficacy 

    Gamst-Klaussen, Thor; Steel, Piers; Svartdal, Frode (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-05)
    Procrastination is related to unhealthy personal financial behaviors, such as postponing retirement savings, last minute shopping, and not paying bills on time. The present paper explores factors that could explain why procrastinators demonstrate more financial problems compared to non-procrastinators. Study 1 (N = 675) focused on planning, as both procrastination and poor financial habits are ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-01)
    Concerns about the veracity of psychological research have been growing. Many findings in psychological science are based on studies with insufficient statistical power and nonrepresentative samples, or may otherwise be limited to specific, ungeneralizable settings or populations. Crowdsourced research, a type of large-scale collaboration in which one or more research projects are conducted across ...
  • Striving for wellbeing: The different roles of hedonia and eudaimonia in goal pursuit and goal achievement 

    Thorsteinsen, Kjærsti; Vittersø, Joar (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-09)
    Goals are central to theories of happiness and previous research has shown that successful goal pursuit typically leads to a boost in wellbeing. Taking these ideas further, the current study adopts the distinction between hedonic wellbeing (HWB) and eudaimonic wellbeing (EWB) and suggests that it is the former that increases when goals are achieved. By contrast, EWB is hypothesized to have a causal ...
  • The impact of age-related hearing loss and lateralized auditory attention on spatiotemporal parameters of gait during dual-tasking among community dwelling older adults 

    Gorecka, Marta Maria; Vasylenko, Olena; Espenes, Johan Jacob; Waterloo, Knut; Rodriguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-27)
    This investigation assessed the impact of hearing loss and lateralized auditory attention on spatiotemporal parameters of gait during overground dual-tasking by the use of the dichotic listening task. Seventy-eight right-handed, healthy older adults between 60 and 88 years were assigned to a Young-Old (<70 years) or an Old-Old (>71 years) group. Cognitive assessment and pure tone audiometry were ...
  • Manual dexterity in young and healthy older adults. 2. Association with cognitive abilities 

    Vasylenko, Olena; Gorecka, Marta Maria; Rodriguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-02)
    Currently, little is known about the cognitive constraints underlying manual dexterity decline in aging. Here, we assessed the relationship between cognitive function and dexterity in 45 young and 55 healthy older adults. Effects of gender on the cognition‐dexterity association were also explored. Cognitive assessment comprised neuropsychological tests of executive function, working memory, attention, ...
  • Cortisol levels and cognitive profile in major depression: A comparison of currently and previously depressed patients 

    Høifødt, Ragnhild Sørensen; Waterloo, Knut; Wang, Catharina Elisabeth Arfwedson; Eisemann, Martin; Figenschau, Yngve Anton; Halvorsen, Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-22)
    The association between depressive symptoms and elevated cortisol levels, and depression and cognitive functioning, has been less robust in outpatients with symptoms in the mild to moderate range. Furthermore, the association between elevated cortisol levels and cognitive functioning is unclear. In the present study, currently depressed (<i>n</i> = 37), previously depressed (<i>n</i> = 81) and never ...
  • Stereotype threat-effects for Turkish-origin migrants in Germany: Taking stock of cumulative research evidence 

    Froehlich, Laura; Mok, Sog Yee; Martiny, Sarah E.; Deaux, Kay (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-24)
    Turkish-origin migrants on average show lower academic performance than Germans. This achievement gap cannot be fully explained by socio-economic differences between the groups. Negative competence stereotypes about Turkish-origin students predict the causal attributions that German preservice teachers make for migrants’ academic underperformance. Specifically, the more strongly preservice teachers ...
  • The Role of Estrogen Receptor β (ERβ) in the Establishment of Hierarchical Social Relationships in Male Mice 

    Nakata, Mariko; Ågmo, Anders j; Satoshi, Shoko; Ogawa, Sonoko (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-22)
    Acquisition of social dominance is important for social species including mice, for preferential access to foods and mates. Male mice establish social rank through agonistic behaviors, which are regulated by gonadal steroid hormone, testosterone, as its original form and aromatized form. It is well known that estrogen receptors (ERs), particularly ER α (ERα), mediate effects of aromatized testosterone, ...
  • Hospitals implementing changes in law to protect children of ill parents: A cross-sectional study 

    Skogøy, Bjørg Eva; Sørgaard, Knut W.; Maybery, Darryl; Ruud, Torleif; Stavnes, Kristin Anne; Kufås, Elin; Peck, Gro Christensen; Thorsen, Eivind; Lindstrøm, Jonas Christoffer; Ogden, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-06)
    <i>Background</i>: Norway is one of the first countries to require all health professionals to play a part in prevention for children of parents with all kinds of illnesses (mental illness, drug addiction, or severe physical illness or injury) in order to mitigate their increased risk of psychosocial problems. Hospitals are required to have child responsible personnel (CRP) to promote and ...
  • Social identity threat in interpersonal relationships: Activating negative stereotypes decreases social approach motivation 

    Martiny, Sarah E.; Nikitin, Jana (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-15)
    Research has shown that social identity threat can have a broad variety of negative consequences. However, not much is known about the consequences of social identity threat on interpersonal relationships. In the present research, we hypothesize that experiencing social identity threat decreases people’s social approach motivation toward other people related to the stereotyped domain. Specifically, ...
  • Effects of age and working memory load on syntactic processing: An event-related potential study 

    Alatorre-Cruz, Graciela C; Silva-Pereyra, Juan; Fernandez, Thalia; Rodriguez-Camacho, Mario A; Castro Chavira, Susana Angelica; Sanchez-Lopez, Javier (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-04)
    Cognitive changes in aging include working memory (WM) decline, which may hamper language comprehension. An increase in WM demands in older adults would probably provoke a poorer sentence processing performance in this age group. A way to increase the WM load is to separate two lexical units in an agreement relation (i.e., adjective and noun), in a given sentence. To test this hypothesis, event-related ...
  • A randomized controlled trial on a smartphone self-help application (Be Good to Yourself) to reduce depressive symptoms 

    Lüdtke, Thies; Pult, Lilian Klara; Schröder, Johanna; Moritz, Steffen; Bücker, Lara (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-29)
    Depressive symptoms are common, yet only a subgroup of individuals receive adequate treatment. To reduce the treatment gap, several online self-help programs have been developed, yielding small to moderate effects. We developed a smartphone self-help application addressing depressive symptoms. We sought to evaluate its feasibility and efficacy in participants reporting a subjective need for help (a ...
  • 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 ...
  • High levels of incidental physical activity are positively associated with cognition and EEG activity in aging 

    Sanchez-Lopez, Javier; Silva-Pereyra, Juan; Fernandez, Thalia; Alatorre-Cruz, Graciela C; Castro Chavira, Susana Angelica; Gonzalez-Lopez, Mauricio; Sanchez-Moguel, Sergio M (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-25)
    High levels of physical activity seem to positively influence health and cognition across the lifespan. Several studies have found that aerobic exercise enhances cognition and likely prevents cognitive decline in the elderly. Nevertheless, the association of incidental physical activity (IPA) with health and cognition during aging has not been studied. Thus, the aim of this study was to evaluate the ...
  • Do mothers also "manipulate" grandparental care? 

    Busch, Mari Veierud; Olaisen, Sandra; Bruksås, Ina Jeanette; Folstad, Ivar (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-15)
    Paternity uncertainty has proven to be a robust ultimate hypothesis for predicting the higher investment in grandchildren observed among maternal grandparents compared to that of the paternal grandparents. Yet the proximate mechanisms for generating such preferred biases in grandparental investment remain unclear. Here we address two different questions for better understanding the proximate mechanisms ...
  • Skiing and thinking about it: Moment-to-moment and retrospective analysis of emotions in an extreme sport 

    Hetland, Audun; Vittersø, Joar; Bø Wie, Simen Oscar; Kjelstrup, Eirik Refsnes; Mittner, Matthias; Dahl, Tove Irene (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-20)
    Happiness is typically reported as an important reason for participating in challenging activities like extreme sport. While in the middle of the activity, however, participants do not seem particularly happy. So where does the happiness come from? The article proposes some answers from a study of facially expressed emotions measured moment-by-moment during a backcountry skiing event. Self-reported ...
  • A variation of the social context in the warm-up period influences 18-month-olds’ imitation 

    Kim, Ziyon; Óturai, Gabriella; Király, Ildikó; Hirte, Monika; Knopf, Monika (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-06)
    The present study aimed to investigate how the prior social disposition of a model in a warm-up period influences 18-month-old infants’ subsequent imitation. Infants were randomly assigned to an interactive and social warm-up period (<i>n</i> = 19) or a non-interactive and non-social warm-up period (<i>n</i> = 19) with the model prior to the imitation task. They then participated in an imitation ...
  • Head models of healthy and depressed adults for simulating the electric fields of non-invasive electric brain stimulation [version 2; referees: 2 approved] 

    Boayue, Nya Mehnwolo; Csifcsak, Gabor; Puonti, Oula; Thielscher, Axel; Mittner, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-06)
    During the past decade, it became clear that the electric field elicited by non-invasive brain stimulation (NIBS) techniques such as transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) are substantially influenced by variations in individual head and brain anatomy. In addition to structural variations in the healthy, several psychiatric disorders are characterized ...
  • When Life Happens: Investigating Short and Long-Term Effects of Life Stressors on Life Satisfaction in a Large Sample of Norwegian Mothers 

    Dyrdal, Gunvor Marie; Røysamb, Espen; Nes, Ragnhild Bang; Vittersø, Joar (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-25)
    The purpose of this study was to examine the impact of major life stressors on the short and long-term life satisfaction (LS) of Norwegian mothers using data from the Norwegian Mother and Child Cohort study (MoBa, N = 46,342). Data on LS were collected at T1 (6 months postpartum) and T3 (36 months postpartum), and data on life stressors at T2 (18 months postpartum) and T3. Altogether, 24,216 ...
