A previous study assessed the fit of the FPQ-III and the FPQ-SF in a Norwegian non-clinical ... -
Investigating the effect of physiological need states on palatability and motivation using microstructural analysis of licking
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-01)The study of consummatory responses during food intake represents a unique opportunity to investigate the physiological, psychological and neurobiological processes that control ingestive behavior. Recording the occurrence and temporal organization of individual licks across consumption, also called lickometry, yields a rich data set that can be analyzed to dissect consummatory responses into different ... -

Sammenheng mellom mindset og tankestrategi
(Master thesis; Mastergradsoppgave, 2019-05-09)Prefaktiske tanker – tanker om konsekvenser av tenkte handlinger før de utføres – kan være gunstig for å forstå hvordan fremtidige mål kan oppnås. (Epstude, Scholl & Roese, 2016), mens kontrafaktisk tanker – tanker om hva som alternativt kunne skjedd – er funksjonell ved å hjelpe individet med atferdsregulering (Epstude & Roese, 2008). Denne studien undersøker sammenhengen mellom studenters prefaktiske- ... -

Sykefravær og barrierer mot retur til arbeid. En litteraturgjennomgang av ikke-helseårsakers betydning for sykefravær
(Master thesis; Mastergradsoppgave, 2019-05-02)Samtidig som arbeidslivet i Norge preges av høy sysselsetting, høyt utdanningsnivå og god folkehelse, er sykefraværet det høyeste blant OECD-landene. Langtidssykefraværet står for de fleste av sykefraværsdagene, og det er viktig å forstå hvorfor ikke flere kommer tilbake i jobb gjennom dagens sykefraværsordning. Det er gjort mye forskning på både utløsende og opprettholdende helseårsaker til sykefravær, ... -
Can perinatal SSRI exposure affect sexual behavior later in life? Early Developmental Fluoxetine Exposed Female Rats Observed in a Seminatural Environment
(Master thesis; Mastergradsoppgave, 2019-05-02)Renewed interests in sexual behavior research stems from human reports of negative symptoms of selective serotonin reuptake inhibitor (SSRI). The use of SSRIs, during pregnancy might impact the developing child, due to the drug’s ability to cross the placenta and also be present in breastmilk. Perinatal SSRI exposure thus elevates serotonin levels in the developing brain, during phases where serotonin ... -
Rationality: Can it be predicted by cognitive effort, ability and thinking disposition? On the role of willingness to exert cognitive effort, thinking disposition and executive function on deliberate reasoning tasks both with and without a heuristic response.
(Master thesis; Mastergradsoppgave, 2019-05-02)Å bruke intuisjon og magefølelsen, når det som egentlig kreves er nøye resonnering kan føre til feilaktige vurdering og beslutninger, ikke bare på quiz, men også ha store konsekvenser i hverdagen. Så hvorfor gjør vi det? En vanlig forklaring er at vi gjøre det fordi det er strevsomt og krever innsats å bedrive nøye resonnering, innsats vi til vanlig ikke liker. In denne studien kastet vi lys over ... -
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 ... -

Third-party prosocial behavior in adult female rats is impaired after perinatal fluoxetine exposure
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-26)SSRIs are commonly used to treat pregnant women with depression. However, SSRIs can cross the placenta and affect the development of the fetus. The effects of perinatal SSRI exposure, and especially the effects on social behavior, are still incompletely documented. This study first aims to investigate whether rats show prosocial behavior in the form of consolation behavior. Secondly, it aims to ... -

A longitudinal investigation of immigrant children’s ethnic and national identities
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-22)How immigrants define their ethnicity and nationality is relevant for integration: They can identify with their ethnic group, the receiving society, and a combination of both. A longitudinal study with elementary-school children with migration background (N = 200; age 9-10) in Germany investigated the predictors and stability of ethnic and national identity. Ethnic identity was more highly endorsed ... -

Intermittent Absence of Control during Reinforcement Learning Interferes with Pavlovian Bias in Action Selection
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-02)The ability to control the occurrence of rewarding and punishing events is crucial for our well-being. Two ways to optimize performance are to follow heuristics like Pavlovian biases to approach reward and avoid loss or to rely more on slowly accumulated stimulus–action associations. Although reduced control over outcomes has been linked to suboptimal decision-making in clinical conditions associated ...
