Cloninger's psychobiological model of personality integrates contributions from behavioral genetics, neurobiology, and psychology in the description of the human personality. The temperament and character inventory (TCI) is its assessment instrument. The Brazilian Portuguese version of the TCI has shown good psychometric properties. However, Portuguese spoken in Brazil presents marked and substantial differences to that spoken in Portugal, and no study has yet described the psychometrics of the European Portuguese version...

Childhood trauma (CT) is associated with long-lasting alterations of the hypothalamic-pituitary-adrenal (HPA) axis and elevated risk for stress exposure in adulthood. Although HPA alterations are present in the early aftermath of trauma, it remains unclear how initial HPA activity is associated with subsequent stress exposure and whether CT exposure influences the strength and direction of this association. The present study examined prospective associations between hair cortisol content (HCC) and stress exposure from baseline to 3-month follow-up in young adult women with recent (i...

OBJECTIVE: Somatic symptom disorder (SSD) often co-occurs with major depressive disorder (MDD). Both conditions share common psychobiological and biobehavioral characteristics, but little is known about differential patterns in brain function. In this study, we compared resting-state functional brain connectivity between SSD and MDD using quantitative electroencephalography (QEEG). METHODS: Fifteen patients with SSD (SSD group), 15 patients with MDD (MDD group), and 15 healthy volunteers (HC group) participated in this study...

AIMS: Recreational drugs are taken for their positive mood effects, yet their regular usage damages well-being. The psychobiological mechanisms underlying these damaging effects will be debated. METHODS: The empirical literature on recreational cannabinoids and stimulant drugs is reviewed. A theoretical explanation for how they cause similar types of damage is outlined. RESULTS: All psychoactive drugs cause moods and psychological states to fluctuate...

REVIEW
Asael Lubotzky, Adi Aran
Any medical treatment, whether it be medication, behavioral therapy or medical procedure, can affect the patient in a very complex way. Each of these forms of medical treatment have both psychobiological and physiological effects on the patient, with interactions between those levels. When considering the specific efficacy of a new treatment, there is therefore a need to neutralize the psychobiological effect by comparing the effect of the treatment to the effect of a placebo - a treatment involving similar characteristics which does not produce that physiological effect...

This review provides a broad overview of my research group's work on social buffering in human development in the context of the field. Much of the focus is on social buffering of the hypothalamic-pituitary-adrenocortical (HPA) system, one of the two major arms of the mammalian stress system. This focus reflects the centrality of the HPA system in research on social buffering in the fields of developmental psychobiology and developmental science. However, buffering of the cardiovascular and autonomic nervous system is also discussed...

In order to understand psychobiological responses to stress it is necessary to observe how people react to controlled stressors. A range of stressors exist for this purpose; however, laboratory stressors that are representative of real life situations provide more ecologically valid opportunities for assessing stress responding. The current study assessed psychobiological responses to an ecologically valid laboratory stressor involving multitasking and critical evaluation. The stressor elicited significant increases in psychological and cardiovascular stress reactivity; however, no cortisol reactivity was observed...

This study examined the effect of playing matches against different opponent teams (hard match; HM, medium match; MM, and easy match; EM) on pre-match testosterone concentration (T), pre-to-post match cortisol (C) concentration, and pre-competitive anxiety (CSAI-2 questionnaire) in 20 elite male basketball players. One training session (TS) was also assessed (control condition). Saliva steroids were determined by ELISA. The pre-T concentration was significantly lower for the TS (163±54pmolL(-1)), compared to the three official matches (EM: 208±82pmolL(-1), MM: 213±57pmolL(-1), and HM: 218±37pmolL(-1)) (p<0...

BACKGROUND: This pilot study investigated links between psychobiological indicators of work productivity, prolonged desk sitting, and conditions whereby office workers were able to interrupt sitting using a sit-stand or treadmill desk. METHODS: Twenty participants visited our laboratory and completed their own desk work in counterbalanced sit-only, sit-stand (Varidesk Pro Plus 48(TM)) and sit-walk conditions (Infiniti TR1200-DTS(TM)). Steady state visually evoked potentials (SSVEPs) calculated from electroencephalography recordings during a set task at the end of the workday assessed attentional resource...

The presented study refers to cognitive aspects of burnout as the effects of long-term work-related stress. The purpose of the study was to investigate electrophysiological correlates of burnout to explain the mechanisms of the core burnout symptoms: exhaustion and depersonalization/cynicism. The analyzed error-related electrophysiological markers shed light on impaired cognitive mechanisms and the specific changes in information-processing in burnout. In the EEG study design (N = 80), two components of error-related potential (ERP), error-related negativity (ERN), and error positivity (Pe), were analyzed...

OBJECTIVE: Fibromyalgia (FM) patients may present psychopathology and some characteristic personality traits that may affect their adaptation to the disease. This paper aims to study the relationship between personality dimensions according to the psychobiological model of Cloninger and the presence of psychopathology. METHOD: The study sample consisted of 42 patients with FM and 38 healthy controls. The assessment instruments administered were the Temperament and Character Inventory (TCI-R) and the Millon Clinical Multiaxial Inventory (MCMI-III)...

The present studies examined the influence of playing venue on psychobiological responses in male soccer players. Many studies have demonstrated the existence of a home advantage, wherein teams perform better at home than away. A recent focus has attempted to explain this advantage from a psychobiological perspective, with studies showing hormonal differences with regard to venue, game outcome, dominance and perceived stress. Two studies investigated testosterone and cortisol responses in relation to home and away venues...

Background and objectives: In many settings, partnered, invested fathers have lower testosterone than single men or fathers who are not involved in caregiving. Reduced testosterone has been identified as a risk factor for multiple chronic diseases, and men's health also commonly varies by life history status. There have been few tests of whether variation in testosterone based on partnering and parenting has implications for men's health. Methodology: We analysed data from a US population-representative sample (NHANES) of young-to-middle aged US men (n = 875; mean age: 29...

A contribution to a special issue on Hormones and Human Competition. Psychoneuroendocrine effects of competition have been widely accepted as a clear example of the relationship between androgens and aggressive/dominant behavior in humans. However, results about the effects of competitive outcomes are quite heterogeneous, suggesting that personal and contextual factors play a moderating role in this relationship. To further explore these dimensions, we aimed to examine (i) the effect of competition and its outcome on the psychobiological response to a laboratory competition in young men, and (ii) the moderating role of some cognitive dimensions such as causal attributions...

K R Barton, Y Yazdani, N Ayer, S Kalvapalle, S Brown, J Stapleton, D G Brown, K A Harrigan
Near misses and losses disguised as wins have been of interest to gambling researchers and policymakers for many years (e.g., Griffiths in J Gambl Stud 9(2):101-120, 1993). This systematic literature review describes the behavioural, psychological, and psychobiological effects of near misses and losses disguised as wins (LDWs) in an effort to evaluate their precise influence on the player and to highlight areas requiring further investigation. A systematic search for relevant studies was conducted using Scopus, PubMed, PsycINFO, ProQuest Sociology databases, and the Gambling Research Exchange Ontario Knowledge Repository...

Mark Reybrouck, Tuomas Eerola
The aim of this contribution is to broaden the concept of musical meaning from an abstract and emotionally neutral cognitive representation to an emotion-integrating description that is related to the evolutionary approach to music. Starting from the dispositional machinery for dealing with music as a temporal and sounding phenomenon, musical emotions are considered as adaptive responses to be aroused in human beings as the product of neural structures that are specialized for their processing. A theoretical and empirical background is provided in order to bring together the findings of music and emotion studies and the evolutionary approach to musical meaning...

Sexual health severely decreases with age. For males older than 40 years, erectile dysfunction (ED) is the most common sexual disorder. Although physical and psychological risk factors for ED have been identified, protective factors are yet to be determined. To date, no study has examined endocrine and psychosocial factors in parallel with regard to their modifying effect on the age-related increase in ED. Two hundred and seventy-one self-reporting healthy men aged between 40 and 75 years provided both psychometric data on sexual function and a set of potential psychosocial protective factors, and saliva samples for the analysis of steroid hormones and proinflammatory cytokines...

BACKGROUND: When a memory is recalled, it may again exist in a labile state and stored information becomes amenable to change, a psychobiological process known as reconsolidation. Exposure therapy for anxiety disorders involves accessing a fear memory and modifying it with less fearful information. A preclinical study reported that providing a reminder of a fear memory 10 min prior to extinction training in humans decreased fear up to 1 year later (Schiller et al., 2010). METHODS: For this pilot clinical study, we used virtual reality exposure therapy (VRE) for fear of flying (FoF) to determine if using a cue to reactivate the memory of the feared stimulus 10 min prior to exposure sessions leads to fewer anxiety-related behaviors and a more durable response compared to a neutral cue...

Although behavioral inhibition (BI) is clearly identified as a temperamental risk factor for childhood anxiety psychopathology, much less is known about whether the strength of this association may vary as a function of parasympathetic nervous system regulation in children with anxiety disorders. To build upon extant research in this area, the present study examined whether respiratory sinus arrhythmia (RSA) can explicate the conditions in which BI is linked to increased symptom severity among anxiety-disordered children (N = 44; M = 9...
