(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-02-05)Background Little is known about the psychological prerequisites for weight loss maintenance after bariatric surgery. A first step in investigating whether existing knowledge of conservative weight loss treatment is applicable for lifestyle interventions postoperatively is to compare specific psychological characteristics at baseline. The aim of this study was to compare patients scheduled for ... -
The computer game training effect for women may depend on initial spatial ability scores
(Master thesis; Mastergradsoppgave, 2010-05-01)In this project we tried to explore what it is in games that may enhance spatial abilities. Previous research has shown that action games may enhance gamers’ scores on the Mental Rotation test (MRT), while evidence is found both for and against that puzzle games could do the same. We used three different games, and one control group, with a total of 32 participants matched over these four groups. ... -
Conducting Fieldwork with San and Hadza (Post-)Hunter-Gatherer Communities in Africa: Regulatory and Ethical Issues
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-28)In this paper, we address some of the challenges and opportunities of conducting international research in psychology. We examine issues that arise from working in contexts that differ substantially from those in which most psychological research is still conducted. We take our experiences with Tanzanian and Namibian (post-)hunter-gatherers as a starting point for discussing regulatory and ethical ... -
The Confidence Database
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-03)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 ... -
The Consumer Science of Sharing: A Discussant's Observations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-09)This discussant’s response to the collected articles on the consumer behavior of sharing draws on a 1983–99 record of research on the psychology of ownership and property. The major recommendations here are: (1) that sharing be defined as the simultaneous or sequential use of an object (e.g., car), a space (e.g., living room), or an intangible (e.g., identity) by more than one individual; (2) that ... -
Contingency awareness and its effects on fear-potentiated startle and extinction
(Master thesis; Mastergradsoppgave, 2019-05-01)Fear-potentiated startle is defined as an increase in the magnitude of the startle reflex in the presence of a stimulus that has been paired with an aversive stimulus or event. It has been debated how much awareness of contingencies can affect fear-potentiated startle and the extinction of this. A conditional discrimination procedure was adapted to a human fear-potentiated startle paradigm in 33 ... -
A cooperative function for multisensory stimuli in the induction of approach behavior of a potential mate
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-17)Intrasexual competition is an important element of natural selection in which the most attractive conspecific has a considerable reproductive advantage over the others. The conspecifics that are approached first often become the preferred mate partners, and could thus from a biological perspective have a reproductive advantage. This underlines the importance of the initial approach and raises the ... -

Cortisol levels and cognitive profile in major depression: A comparison of currently and previously depressed patients
(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 ... -
Covid-19 pandemic lessons: uncritical communication of test results can induce more harm than benefit and raises questions on standardized quality criteria for communication and liability
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-21)Background - The COVID-19 pandemic is characterized by both health and economic risks. A ‘safety loop’ model postulates risk-related decisions are not based on objective and measurable risks but on the subjective perception of those risks. We here illustrate a quantification of the difference between objective and subjective risks.<p> <p>Method - The objective risks (or chances) can be obtained ... -
A creative destruction approach to replication: Implicit work and sex morality across cultures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-03)How can we maximize what is learned from a replication study? In the creative destruction approach to replication, the original hypothesis is compared not only to the null hypothesis, but also to predictions derived from multiple alternative theoretical accounts of the phenomenon. To this end, new populations and measures are included in the design in addition to the original ones, to help determine ... -

The Resilience Scale for Adults (RSA) is a measure of protective factors. The evidence supporting its construct validity is good, however evidence of cross-cultural validity is modest. The present study explored the factorial invariance of the RSA across a Brazilian and a Norwegian sample, as well as ... -
Crowdsourcing Hypothesis Tests: Making Transparent How Design Choices Shape Research Results
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-16)To what extent are research results influenced by subjective decisions that scientists make as they design studies? Fifteen research teams independently designed studies to answer five original research questions related to moral judgments, negotiations, and implicit cognition. Participants from 2 separate large samples (total N 15,000) were then randomly assigned to complete 1 version ... -
Cutoff criteria for the placebo response: a cluster and machine learning analysis of placebo analgesia.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-28)Computations of placebo effects are essential in randomized controlled trials (RCTs) for separating the specific effects of treatments from unspecific effects associated with the therapeutic intervention. Thus, the identification of placebo responders is important for testing the efficacy of treatments and drugs. The present study uses data from an experimental study on placebo analgesia to suggest ...
