Emergenesis. Genetic traits that may not run in families.

Traits that are influenced by a configuration--rather than by a simple sum--of polymorphic genes may not be seen to be genetic unless one studies monozygotic twins (who share all their genes and thus all gene configurations) because such "emergenic" traits will tend not to run in families. Personal idiosyncrasies that have been found to be surprisingly concordant among MZ twins separated in infancy and reared apart may be emergenic traits. More speculatively, important human traits like leadership, genius in its many manifestations, being an effective therapist or parent, as well as certain psychopathological syndromes may also be emergenic. These ideas reemphasize the importance of the role played in human affairs by genetic variation.     

Perceptions of Self and Relationship with Parents in Aggressive and Nonaggressive Rejected Children

This study examined the perceptions of self and the attachment relationship to parents in aggressive and nonaggressive rejected children, as compared to children with an average or popular sociometric status. Participants were 216 children from grades 3 and 4. They completed peer nomination measures, the Self-Perception Profile for Children (SPPC), and the Security Scale (mother and father form). Results generally confirmed the assumption that only the nonaggressive rejected children perceive themselves as less competent and worthy as a person than the more popular children. Aggressive rejected children did not report lower feelings of global self-worth or competence, although they did report lower levels of social acceptance. Furthermore, rejected-nonaggressive children perceived the relationship with their father (but not with their mother) as less secure than did the more popular children. Logistic regression analyses suggested that the linkage between felt security with father and rejected-nonaggressive status was mediated by children's self-worth. Implications for attachment theory and for the hypothesized heterogeneity among rejected children are discussed.     

Auditory contagious yawning in domestic dogs (Canis familiaris): first evidence for social modulation

Dogs' capacity to 'catch' human yawns has recently attracted the attention of researchers in the field of animal cognition. Following recent studies suggesting that contagion yawning in humans, and some other primates, is empathy-related, some authors have considered the possibility that the same mechanism may underlie contagious yawning in dogs. To date, however, no positive evidence has been found, and more parsimonious hypotheses have been put forward. The present study explored the 'contagion-only' hypothesis by testing whether the mere sound of a human yawn can be sufficient to elicit yawning in dogs, in a way that is unaffected by social-emotional factors. Unexpectedly, results showed an interesting interplay between contagion and social effects. Not only were dogs found to catch human yawns, but they were also found to yawn more at familiar than unfamiliar yawns. Although not allowing for conclusive inferences about the mechanisms underlying contagious yawning in dogs, this study provides first data that renders plausible empathy-based, emotionally connected, contagious yawning in these animals.     

Bilingualism and adult differences in inhibitory mechanisms: evidence from a bilingual stroop task

The present investigation examined the functioning of inhibitory mechanisms in younger and older bilinguals using a bilingual version of the Stroop test. The study predicted different patterns of age related decline in inhibitory mechanisms (inter- and intralingual interference) in bilinguals depending on their level of proficiency. Consistent with expectations, older bilinguals were slower when they responded in their non-dominant language. Furthermore, older unbalanced bilinguals showed greater interlingual interference when they responded with their second language to visual stimuli written in their dominant language. Balanced bilinguals showed equivalent interference effects between all conditions. These findings suggest that manipulating two languages may enhance the efficiency of inhibitory mechanisms.     

The Construct Validity of Assertion: Contributions of Four Assessment Procedures and Norman's Personality Factors

ABSTRACT The construct validity of assertion was analyzed in three independent correlational studies The convergence of self-reported, laboratory roleplayed, self-observed, and peer-rated measures was examined, as well as their relationship to Norman's peer-rated five personality factors of extraversion, agreeableness, conscientiousness, emotional stability, and culture Twenty-three and 29 undergraduate students participated in Studies 1 and 2, respectively In general, results showed poor convergence among assertiveness measures even when increasing the representativeness and reliability of the role-played laboratory and self-observed measures, as in Study 2 In Study 3, the role-playing test was abandoned and 45 subjects served as peers for one another The results of Study 3 supported the prediction that assertiveness measures showed at least moderate convergence, in addition there were significant relationships between assertiveness and extraversion and between peer-rated assertiveness and agreeableness, conscientiousness, and culture The relative contribution of each assessment procedure to the construct validity of assertion is discussed     

Who takes driving licence point recovery courses in France? Comparison between course-takers and ordinary drivers

A self-administered questionnaire was answered by 2014 drivers, 853 of whom were taking a course. The data were analyzed aiming to identify the factors that are linked to taking the course, i.e. to recurrent reoffending.The course-takers, of whom 89% were male, admitted committing more violations than the control group. They had more accidents. More male course-takers than controls reported not being happy, and they more frequently had high extroversion scores.The multivariate analysis showed that, among men, taking the course was associated with the mileage, the feeling of being almost certain to be charged for an offence and having a high risk of losing one’s licence, in addition to being young, having a large number of brothers and sisters, higher socio-occupational category and smoking. Among women, in spite of the small number of them on the course, the mileage, the feeling of having a high risk of losing one’s licence, driving alone, the mental representation of their own vehicle as an extension of their office, and defining themselves as liking to take risks during leisure activities were significantly linked to taking a points recovery course.Those taking the course were not therefore doing so by chance; they differed from the general population of drivers, which was also precisely described with regard to driving habits and representations.Recommendations are then made in order to redirect the content of courses more towards introspection than technical matters.     

Why are attitude–behaviour inconsistencies uncomfortable? Using motivational theories to explore individual differences in dissonance arousal and motivation to compensate

Using cognitive dissonance theories and self-determination theory, we explored the role of individual differences in global and contextual motivational orientations on dissonance arousal processes following spontaneous attitude–behaviour inconsistencies (ABIs). Study 1 (N = 382) showed that individual differences in global motivation relate to the frequency of ABIs and dissonance arousal across important life domains. Studies 2 (N = 282) and 3 (N = 202) showed that individual differences in contextual motivation toward the environment predict the relative frequency of ABIs and the quantity and quality of proximal motivation to compensate for ABIs in that context. Autonomous motivation was associated with a tendency to compensate for ABIs to both reduce dissonance and restore self-integrity. Controlled motivation disposed individuals to reduce dissonance to protect ego-invested self-structures, and to be indifferent to non self-threatening ABIs. Amotivation left people indifferent to ABIs. Individual differences in motivational orientations could explain why ABIs are uncomfortable and motivate people to compensate differently when they face ABIs.     

Quality of Life in Patients with Recurrent Vasovagal or Unexplained Syncope: Influence of Sex, Syncope Type and Illness Representations

Health-related quality of life (QoL) is reduced in patients with recurrent vasovagal (VVS) or unexplained (US) syncope. Little is known regarding these patients’ QoL as pertains to their capacity to attain their life goals. Factors influencing QoL, such as sex, syncope type and illness representations have not been studied. Our objective is to examine the relationship between illness representations and QoL, as well as possible sex and syncope type differences. One hundred and four patients undergoing tilt-table testing (TTT) for recurrent syncope were interviewed one month before TTT, using questionnaires. Data were analysed using ANCOVAs, a-priori Helmert contrasts for illness representations, and regressions. Patients with US had a poor QoL compared to those with VVS [F(1, 91) = 10.46; p < 0.01], particularly in men (p < 0.01). Patients with higher perceived syncope severity showed an impoverished QoL relative to those with less severe perceptions [F(1, 91) = 5.47; p < 0.05]. A hierarchical regression revealed that illness representations mediate the impact of lifetime number of syncope on QoL. In conclusion, QoL is reduced in these patients, and is influenced by illness representations. Helping patients change their perceptions about their syncope may be an efficient way to promote QoL.
