    • Protein Appetite Drives Macronutrient-Related Differences in Ventral Tegmental Area Neural Activity 

      Chiacchierini, Giulia; Naneix, Fabien; Peters, Kate Z; Aspergis-Schoute, John; Snoeren, Eelke; McCutcheon, James Edgar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-09)
      Control of protein intake is essential for numerous biological processes as several amino acids cannot be synthesized de novo, however, its neurobiological substrates are still poorly understood. In the present study, we combined in vivo fiber photometry with nutrient-conditioned flavor in a rat model of protein appetite to record neuronal activity in the VTA, a central brain region for the control ...

    • Protein preference and elevated plasma FGF21 induced by dietary protein restriction is similar in both male and female mice 

      Volcko, Karin Linnea; McCutcheon, James Edgar (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-19)
      Animals that are moderately protein restricted respond to this dietary stress by increasing consumption of protein-containing foods. This is true in many species, including rodents. Rodent models of protein restriction have typically relied on only male subjects, and there are plausible reasons why female rodents may respond differently to dietary protein restriction. To address this gap in ...

    • Protocol for the Northern babies longitudinal study: predicting postpartum depression and improving parent–infant interaction with The Newborn Behavioral Observation 

      Høifødt, Ragnhild Sørensen; Nordahl, Dag; Pfuhl, Gerit; Landsem, Inger Pauline; Thimm, Jens; Ilstad, Linn Kathrin K.; Wang, Catharina Elisabeth Arfwedson (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-27)
      Postpartum depression (PPD) is a prevalent disorder. Studying the factors related to PPD will help to identify families at risk and provide preventive interventions. This can in turn improve the developmental trajectories for the children. Several previous studies have investigated risk factors for PPD. However, few studies have focused on cognitive vulnerability factors. The first aim of the ...

(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 ...

    • The Psychology of leisure experiences. A closer look at liminality and a comparison of (the seemingly very different) activities of friluftsliv and video gaming 

      Torjul, Ingelin Settemsdal (Master thesis; Mastergradsoppgave, 2019-05-02)
      This thesis explored the nature of liminality and experiences, by collecting responses from a sample of 155 Norwegians who partook in the leisure activities friluftsliv or video gaming, by responding to an online questionnaire consisting of various scales measuring liminality, and variables we believed to be more, or less, related to liminality. The variables included, in addition to liminality, ...

    • Psychosis and Psychotic-Like Symptoms Affect Cognitive Abilities but Not Motivation in a Foraging Task 

      ten Velden Hegelstad, Wenche; Kreis, Isabel Viola; Tjelmeland, Håkon; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-31)
      <i>Background and Objective</i>: Goal-directed behavior is a central feature of human functioning. It requires goal appraisal and implicit cost-benefit analyses, i.e., how much effort to invest in the pursuit of a certain goal, against its value and a confidence judgment regarding the chance of attainment. Persons with severe mental illness such as psychosis often struggle with reaching goals. ...

    • Psykologifaget og individuell frigjøring 

      Aandahl, Jakob Biftu (Mastergradsoppgave; Master thesis, 2022-08-23)
      Temaet for denne litteraturoppgaven er kritisk psykologi. Man kan definere kritikk som en metode for å rette oppmerksomhet mot forutsetninger som skjuler seg i vårt vanlige handle- og tenkesett (Madsen, 2012a, s.742). Kritisk psykologi innebærer å ta et metaperspektiv på de faglige forutsetningene som ligger til grunn for det perspektivet faget anlegger på virkeligheten. Disiplinen «kritisk psykologi» ...

    • Pupillary Stroop effects 

      Laeng, Bruno; Ørbo, Marte; Holmlund, Terje; Miozzo, Michele (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      We recorded the pupil diameters of participants performing the words’ color-naming Stroop task (i.e., naming the color of a word that names a color). Non-color words were used as baseline to firmly establish the effects of semantic relatedness induced by color word distractors. We replicated the classic Stroop effects of color congruency and color incongruency with pupillary diameter recordings: ...

    • pypillometry: A Python package for pupillometric analyses 

      Mittner, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-02)
      The size of the human pupil is controlled by pairs of constrictor and dilator muscles that allow its opening (dilation) and closing (constriction) in response to varying lighting conditions (Mathôt, 2018). Importantly, it has long been known that the pupil also reacts to psychological important stimuli (Hess & Polt, 1960) and has been a firmly established tool for studying “mental effort” in the ...
