Kinds of Of Behaviour Selected AbstractsThe assessment of behavioural activation,the relationship between positive emotionality and the behavioural activation systemEUROPEAN JOURNAL OF PERSONALITY, Issue 7 2004Lena C. Quilty Much personality research suggests that the variance in personality can be accounted for by a few dimensions, often hypothesized to be connected to neurological circuits. Gray's (1982) behavioural activation system (BAS) and behavioural inhibition system (BIS) in particular propose to explain for a variety of behaviour. This investigation sought to determine whether Positive Emotionality is an appropriate measure of the BAS, and how Tellegen's (1985) constructs are related to BAS activity. Measures of BAS and Positive Emotionality were administered to undergraduates. Confirmatory factor analyses revealed that, while Positive Emotionality can be used as an indicator of BAS activity, it is better conceived of as a distinct, correlated construct. In addition, not all components of Positive Emotionality were related to BAS activity, and BAS was further related to components of Negative Emotionality and Constraint.

[source] Personality of children with accident-related injuriesEUROPEAN JOURNAL OF PERSONALITY, Issue 4 2003Margarete Vollrath Previous studies based on a variety of behaviour, temperament, and personality measures identified a pattern of over-activity, impulsiveness, emotional instability, and aggressiveness in children who are prone to accidents. The present study is the first to study accident-prone children by means of a comprehensive test for the assessment of the Five Factor model (Hierarchical Personality Inventory for Children (HiPIC) (Mervielde & De Fruyt, 1999). 118 children, aged 6,15 years, who were hospitalized due to an accident-related injury, were contrasted with 184 school-children of the same age. Lower socio-economic status was under-represented in both groups. Children who were exposed to accidents had higher scores on the facets of energy, optimism, and non-shyness (Extraversion domain), and lower scores on the facets of concentration and achievement striving (Conscientiousness domain). There was no indication of higher aggressiveness, impulsiveness, or emotional instability in the group exposed to accidents, and there were no gender-by-accident interactions. Results suggest that there is a relatively benign pattern of personality traits that is related to greater accident hazard in children. Copyright © 2003 John Wiley & Sons, Ltd. [source] Emergence behaviour in children: defining the incidence of excitement and agitation following anaesthesiaPEDIATRIC ANESTHESIA, Issue 5 2002JENNIFER W. COLE MD Background: Children display a variety of behaviour during anaesthetic recovery. The purpose of this study was to study the frequency and duration of emergence behaviour in children following anaesthesia and the factors that alter the incidence of various emergence behaviour following anaesthesia. Methods: A prospective study of children who required outpatient lower abdominal surgery was designed to determine an incidence and duration of emergence agitation. We developed a 5-point scoring scale to study the postanaesthetic behaviour in these children. The scale included behaviour from asleep (score=1) to disorientation and severe restlessness (score=5). Children were scored by a blinded observer every 10 min during the first hour of recovery or until discharge from same day surgery. Results: We found 27 of 260 children experienced a period of severe restlessness and disorientation (score 5) during anaesthesia emergence. Thirty percent of the children (79/260) experienced a period of inconsolable crying or severe restlessness (score 4 or 5) following anaesthesia. The frequency of this behaviour was greatest on arrival in the recovery room, but many children who arrived asleep in the recovery room later experienced a period of agitation or inconsolable crying. Conclusions: Repeated assessments of behaviour following anaesthetic recovery are required to define an incidence and duration of emergence agitation. Emergence agitation occurs most frequently in the initial 10 min of recovery, but many children who arrive asleep experience agitation later during recovery. [source] Population differences in behaviour are explained by shared within-population trait correlationsJOURNAL OF EVOLUTIONARY BIOLOGY, Issue 4 2010JONATHAN N. PRUITT Abstract Correlations in behavioural traits across time, situation and ecological context (i.e. ,behavioural syndromes' or ,personality') have been documented for a variety of behaviours, and in diverse taxa. Perhaps the most controversial inference from the behavioural syndromes literature is that correlated behaviour may act as an evolutionary constraint and evolutionary change in one's behaviour may necessarily involve shifts in others. We test the two predictions of this hypothesis using comparative data from eighteen populations of the socially polymorphic spider, Anelosimus studiosus (Araneae, Theriidae). First, we ask whether geographically distant populations share a common syndrome. Second, we test whether population differences in behaviour are correlated similarly to within-population trait correlations. Our results reveal that populations separated by as much as 36° latitude shared similar syndromes. Furthermore, population differences in behaviour were correlated in the same manner as within-population trait correlations. That is, population divergence tended to be along the same axes as within-population covariance. Together, these results suggest a lack of evolutionary independence in the syndrome's constituent traits. [source] Sexual Differentiation of Behaviour in Monkeys: Role of Prenatal HormonesJOURNAL OF NEUROENDOCRINOLOGY, Issue 4 2009K. Wallen The theoretical debate over the relative contributions of nature and nurture to the sexual differentiation of behaviour has increasingly moved towards an interactionist explanation that requires both influences. In practice, however, nature and nurture have often been seen as separable, influencing human clinical sex assignment decisions, sometimes with disastrous consequences. Decisions about the sex assignment of children born with intersex conditions have been based almost exclusively on the appearance of the genitals and how other's reactions to the gender role of the assigned sex affect individual gender socialisation. Effects of the social environment and gender expectations in human cultures are ubiquitous, overshadowing the potential underlying biological contributions in favour of the more observable social influences. Recent work in nonhuman primates showing behavioural sex differences paralleling human sex differences, including toy preferences, suggests that less easily observed biological factors also influence behavioural sexual differentiation in both monkeys and humans. We review research, including Robert W. Goy's pioneering work with rhesus monkeys, which manipulated prenatal hormones at different gestation times and demonstrated that genital anatomy and specific behaviours are independently sexually differentiated. Such studies demonstrate that, for a variety of behaviours, including juvenile mounting and rough play, individuals can have the genitals of one sex but show the behaviour more typical of the other sex. We describe another case, infant distress vocalisations, where maternal responsiveness is best accounted for by the mother's response to the genital appearance of her offspring. Taken together, these studies demonstrate that sexual differentiation arises from complex interactions where anatomical and behavioural biases, produced by hormonal and other biological processes, are shaped by social experience into the behavioural sex differences that distinguish males and females.

Spokes msc bsc(hons) Violence in psychiatric inpatient units is a major and growing problem. Research interest has primarily focussed on patient characteristics. The role of staff factors and the antecedents of violent incidents has been neglected, despite the fact that staff factors and behaviour may be more readily amenable to change than patient characteristics. The HOVIS study sought to obtain the views of a sample of mental health nurses in current clinical practice about staff-related factors, which they perceive to contribute to, or protect against, the occurrence of violent incidents. A total of 108 nurses working in psychiatric acute admission, intensive care and low secure units, in two NHS Trusts were interviewed using a specially designed semistructured interview schedule. These nurses identified a variety of behaviours, clinical skills, personal characteristics and interpersonal skills that they believe impact on the occurrence of violent incidents. These findings are discussed in relation to their possible training and managerial implications. [source] | ||||||||||
