  • Endocrine, liver-derived IGF-I is of importance for spatial learning and memory in old mice.
  • 2006
  • Ingår i: The Journal of endocrinology. - 0022-0795. ; 189:3, s. 617-27

    • IGF-I is a neuroprotective hormone, and neurodegenerative disorders, including Alzheimer's disease, have been associated with decreased serum IGF-I concentration. In this study, IGF-I production was inactivated in the liver of adult mice (LI-IGF-I(-/-)), resulting in an approximately 80-85% reduction of circulating IGF-I concentrations. In young (6-month-old) mice there was no difference between the LI-IGF-I(-/-) and the control mice in spatial learning and memory as measured using the Morris water maze test. In old (aged 15 and 18 months) LI-IGF-I(-/-) mice, however, the acquisition of the spatial task was slower than in the controls. Furthermore, impaired spatial working as well as reference memory was observed in the old LI-IGF(-/-) mice. Histochemical analyses revealed an increase in dynorphin and enkephalin immunoreactivities but decreased mRNA levels in the hippocampus of old LI-IGF-I(-/-) mice. These mice also displayed astrocytosis and increased metabotropic glutamate receptor 7a-immunoreactivity. These neurochemical disturbances suggest synaptic dysfunction and early neurodegeneration in old LI-IGF-I(-/-) mice. The decline in serum IGF-I with increasing age may therefore be important for the age-related decline in memory function.

  • Cultural influences upon health, affect, self-esteem and impulsiveness: An Indonesian-Swedish comparison
  • 2013
  • Ingår i: International Journal of Research Studies in Psychology. - 2243-7781 .- 2243-779X. ; 2:3
  • Tidskriftsartikel (refereegranskat)abstract
    • The present study examines several personal attributes that distinguish the personal profiles of individuals, from Indonesian and Swedish cultures, according to self-reports of positive and negative effect, stress and energy, self-esteem, hospital anxiety and depression, dispositional optimism and health. Indonesian participants expressed both more PA and more NA than Swedish participants but less stress and a higher energy-stress quotient than the Swedish participants. Additionally, the former expressed a higher level of optimism and self-esteem, but also more depression, and less impulsiveness than the latter. Younger participants expressed less positive affect and more negative affect and impulsiveness than older participants who expressed both more stress and a higher energy stress quotient. Regression analyses indicated that PA was predicted by optimism and health whereas NA was predicted by anxiety and depression and impulsiveness and counter predicted by health. The present findings are discussed according to the notion of emotional regulation according to which individuals differ in their use of emotion regulation strategies such as reappraisal and suppression, and these individual differences have implications for affect, well-being, and social relationships.

  • Affectively Motivated: Affective Profiles, Motivation, Stress and Energy
  • 2020
  • Ingår i: Biquarterly Iranian Journal of Health Psychology. ; 2:2, s. 21-32
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: We used the affective profiles model to investigate individual differences in motivation, stress and energy. The aim was to replicate past findings, but we also focused on matched comparisons within individuals with affective profiles that are similar in one affective dimension and differ in the other in order to predict changes when individuals increase/decrease their experience of positive or negative affect. Methods: A total of 567 participants answered the Positive Affect and Negative Affect Schedule, which was used for affective profiling; the Situational Motivation Scale, which measures intrinsic motivation, identified regulation, external regulation, and amotivation; and the Stress-Energy questionnaire. Results: Comparisons between the four different profiles, replicating the past findings, showed that individuals with high affective and self-fulfilling profile scored highest in intrinsic motivation, identified regulation, and energy, while they scored lowest in external motivation, amotivation, and the self-fulfilling profile, also lowest in stress. Additionally, the matched comparisons showed, for example, that levels of intrinsic motivation increase when negative affect levels decrease, and positive affect is kept high when positive affect decreases and negative affect is kept low. Conclusions: One important feature of the affective profiles model is the possibility to compare individuals that are similar in one affect dimension but differ in the other (Garcia, 2011, 2017). This way of discussing individual differences helps to predict what changes could be expected when individuals increase or decrease their experience of positive or negative affect. Importantly, the direction of these changes cannot be addressed from cross-sectional data.

  • The Affective Profile Model in Swedish Police Personnel: Work Climate and Motivation

    • ABSTRACT The study showed that police personnel perceive the work environment depending on their affective profile, these perceptions in turn influence motivation differently for each profile. A positive view on the work environment and intrinsic motivation being related to an affective profile depicted as high positive affect and low negative affect. SUPPORTING SUMMARY Background: The work climate (i.e., employees’ perceptions of how they are treated and managed in their organization) is important when the organizations try to motivate employees to allocate and enhance their efforts into their work. The affective profile model offers something unique over and above the single dimensional framework of affectivity by taking into account how positive (PA) and negative affectivity (NA) interact; these interaction can be used to investigate individual differences in perceptions about the working climate and its influences on motivation. Method: We used the Positive Affect, Negative Affect Schedule to categorize police personnel (N = 595) in four affective profiles: Self-fulfilling (high PA and low NA), low affective (low PA and low NA), high affective (high PA and high NA), and self-destructive (low PA and high NA). Individuals’ perceptions of the work climate were assessed using the Learning Climate Questionnaire which measures seven dimensions: management relations and style, time, autonomy and responsibility, team style, opportunities to develop, guidelines on how to do the job, and contentedness. Finally, we used the Situational Motivation Scale to measure four motivation dimensions: intrinsic motivation, external regulation, identified regulation, and amotivation. Results: Results show that self-fulfilling individuals scored higher on all work climate compared to the other three groups. Regarding motivation, profiles with high PA (self-fulfilling and high affective) scored higher in internal motivation and identified regulation than the profiles with low PA. Self-destructive individuals scored higher in amotivation compared to the other three profiles. Different aspects of the work climate were related to each motivation dimension among affective profiles. Conclusions: These results suggest that individuals may react to the work environment depending on their affective profile. Moreover, how the work environment influences police personnel’s motivation is also a function of the individuals’ distinct affective profile.

  • The impact of work-related stress on the sexual relation quality of the couple
  • 2008
  • Ingår i: Sexologies. - 1158-1360. ; 17, Supplement 1:0
  • Konferensbidrag (refereegranskat)abstract
    • This study is part of a research project including stress, coping-strategies, mood, partnership relation quality, and illhealth. Earlier findings tentatively suggest the health-promoting advantages of positive partnership relations in counteracting the illhealth accruing from various types of general stress and the particular stresses of work occupation. In this study two hundred and twelve participants derived from several different occupations, responded to questionnaires based upon self-report instruments including the Subjective Stress Experience Questionnaire, the Stress and Energy Scale, the Hospital Anxiety and Depression Scale, the Job Stress Survey, Partnership Relations Quality Test, and the Positive and Negative Affect Scale. Gender differences were found in levels of sexual desire and intercourse satisfaction, together with sexual pleasure and more orgasms. The results also indicated that illhealth induced less frequency of caressing, fewer orgasms during intercourse, lower level of intercourse satisfaction and sexual pleasure). Negative affect induced lower levels of intercourse satisfaction and sexual desire. Work related stress induced a lower level of intercourse satisfaction and sexual desire. On the other hand good coping-strategies were related to higher frequency of caressing, intimate communication, intercourse frequency, sexual pleasure, and intercourse satisfaction. Positive affect induced higher level of intercourse satisfaction, sexual pleasure, sexual desire, more orgasms, and greater satisfaction with the sexual life. These results indicate that stress, illhealth, and negative affect impairs a flourishing love life and that coping-strategies and positive affect on the other hand are positive factors for obtaining such a love life.

  • Ingår i: Beyond Neuropsychiatric Diagnotics: Symptoms not Disorders. - Mountain Home, USA. : F.P. Graham Publishing: Mountain Home, USA. ; , s. 477-512

    • Cognitive symptoms, considered in conjunction both with their regional brain and biomarkers as well as affective, attributional and neurodevelopmental components, demonstate ever-increasing complexity to facilate conceptualization yet, unavoidably, bedevil diagnosis in neuropsychiatry even before considerations of the enigmatic processes in memory, such as executive function and working memory, are draw into the myriads of equations that await remedial interpretations. Prefrontal and limbic regions of the brain are involved in a diversity of expressions of cognition, normal or dysfunctional, at synaptic, intracellular and molecular levels that mobilise a concatenation of signaling entities. Serotoninergic neurotransission at prefrontal regions directs cogntive-affective entities that mediate decision-making and goal-directed behaviour. Clinical, non-clinical and basic studies challenge attempts to consolidate the multitude of evidence in order to obtain therapeutic notions to alleviate the disordered status of the diagnosed and yet-to-be diagnosed individuals. Locus of control, a concept of some utility in health-seeking procedures, is examined in three self-reort studies from the perspective of a cognitive-emotional situation through observations of ordinary, ‘healthy’ young and middle-aged individuals, to assess the predictors of internal and external locus of control. A notion based on high level executive functioning in the dorsolateral prefrontal cortex in individuals characterised by internal locus of control is contrasted with a hypofunctional executive DLPFC, characterising individuals that express an external locus of control, is discussed.
