Action-associated modulation of visual event-related potentials evoked by abstract and ecological stimuli
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-09-19)
This study investigated the influence of action‐associated predictive processes on visual ERPs. In two experiments, we sought evidence for sensory attenuation (SA) indexed by ERP amplitude reductions for self‐induced stimuli when compared to passive viewing of the same images. We assessed if SA is (a) present for both ecological and abstract stimuli (pictures depicting hands or checkerboards), (b) ...
Manual dexterity in young and healthy older adults. 1. Age- and gender-related differences in unimanual and bimanual performance
This study aimed to better characterize age‐related differences in dexterity by using an integrative approach where movement times and kinematics were measured for both hands. Forty‐five young (age 19–31) and 55 healthy older adults (age 60–88) were evaluated during unimanual and bimanual performance of the Purdue Pegboard Test. Gender effects were also assessed. From video‐recorded data, movement ...
Behavioral responses to emotional challenges in female rats living in a seminatural environment: The role of estrogen receptors
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-11-06)
Estrogen receptors (ERs) are involved in sexual as well as non-sexual behaviors. In the present study we assessed the effects of stimuli inducing positive or negative affect on sociosexual, exploratory and fear-related behaviors of female rats housed in groups (4 females, 3 males) in a seminatural environment. Ovariectomized females were treated with oil, 17β‑estradiol benzoate (EB, 18 μg/kg), the ...
Increasing propensity to mind‐wander by transcranial direct current stimulation? A registered report
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2019-01-24)
Transcranial direct current stimulation (tDCS) has been proposed to be able to modulate different cognitive functions. However, recent meta‐analyses conclude that its efficacy is still in question. Recently, an increase in subjects’ propensity to mind‐wander has been reported as a consequence of anodal stimulation of the left dorsolateral prefrontal cortex (Axelrod et al., Proceedings of the National ...
Measuring Resilience Across Australia and Norway: Validation and Psychometric Properties of the English Version of the Resilience Scale for Adults.
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2019-04-05)
Resilience has become increasingly important in clinical and health psychology, but only few scales have received good psychometric ratings for assessing various outcomes of resilience. The Resilience Scale for Adults (RSA) is one of the best psychometrically rated scales and has been validated among Norwegian samples. The purpose of this study was to explore the construct validity of the RSA in an ...
Mate Choice could be Random in Female Rats (Rattus norvegicus)
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2017-11-01)
Female mate choice is often investigated in terms of reproductive success in order to understand how male characteristics contribute to sexual attractiveness. Previous studies have found that females rats prefer mating with their first encounter rather than males visited subsequently, suggesting that the rewarding value of this first encounter is enough to reinforce mating with the first partner. ...
The role of adrenoceptors in the central nervous system in male and female rat sexual behavior
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2014-09-10)
Three different phases can be distinguished in rats’ sexual cycle, the introductory (precopulatory), the copulatory and the executive (ejaculatory) phases. In this review, a new analysis of existing pharmacological data is made, both in male and female rats, in which the different aspects of sexual behavior are taken into account. An effort is made to distinguish pharmacological effects on sexual ...
Functions of Vocalization in Sociosexual Behaviors in Rats (Rattus norvegicus) in a Seminatural Environment
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2017-01-09)
Both male and female rats produce vocalizations in the presence of a potential sexual partner. In this study, we evaluated the role of vocalizations in sociosexual behaviors in an ecologically valid procedure. Three males and 4 females were housed in a seminatural environment. In each group, 1 or 2 males and females were devocalized, and the other subjects were sham operated. Sociosexual interactions ...
Preface for Marcel Waldinger special issue on premature ejaculation
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2019-09-13)
The world lost a very dear and brilliant man when Prof Dr Marcel Waldinger passed away this year. I am proud that I got to know him well, and had the chance to learn a lot from him as a scientist. He was passionate about his work related to men and womens sexual dysfunctions, with a special focus on PE, postorgasm illness syndrome, and persistent sexual arousal syndrome.
