Empirical evidence suggests that there are marked associations between positive psychological states and health outcomes, including reduced cardiovascular disease risk and increased resistance to infection. These observations have stimulated the investigation of behavioral and biological processes that might mediate protective effects. Evidence linking positive affect with health behaviors has ...

Ray, J. (2005). Temperamental development in the rat. Department of Psychology, Göteborg University, Sweden. This thesis explores if rats can be said to have a temperament, and if that is the case, how it changes with age and how it is related to brain neurochemistry. Using the hole board and canopy tests (considered to measure exploration and anxiety respectively), behaviour was studied in Wis...

We review current computational models of hippocampal function in learning and memory, concentrating on those that make strongest contact with psychological issues and behavioral data. Some models build upon Marr's early theories for modeling hippocampal field CA3's putative role in the fast, temporary storage of episodic memories. Other models focus on hippocampal involvement in incrementally ...

Stress responses within dyads are modulated by interactions such as mutual emotional support and conflict. We investigated dyadic psychobiological factors influencing intra-individual cortisol variability in response to different challenging situations by testing 132 owners and their dogs in a laboratory setting. Salivary cortisol was measured and questionnaires were used to assess owner and do...

Antisocial personality disorder (ASPD) and the related condition of psychopathy (psychopathic personality) hold strong interest for researchers and practitioners because of their chronic nature and costly impact on society. Individuals who exhibit symptoms of these clinical conditions account for a disproportionate number of crimes, including violent offenses, and are more likely to reoffend th...

The endocannabinoid system plays a physiological natural anti-inflammatory anticancer role and the pharmacological effects of cannabinoids from Cannabis plant simply reflect action endogenous ones. Therefore, therapeutic point view cannot be understood without taking into consideration physio-pathological system. Despite great number potentially molecules with plant, they may synthetized within...
