Buridan’s Secular Demarcation of Logic

Philosophia - In his Tractatus de Consequentiis, the 14th century logician John Buridan states a theorem, which reads like a refutation of Aristotelian Syllogistics. Syllogistics in its usual form,...

Trajectories of Oppositional Defiant Disorder Irritability Symptoms in Preschool Children

This study traces the developmental course of irritability symptoms in oppositional defiant disorder (ODD) from ages 3–5 and examines the psychopathological outcomes of the different trajectories at age 6. Method. A sample of 622 3-year-old preschoolers (311 were boys), followed up until age 6, was assessed yearly with a semi-structured diagnostic interview with parents and at age 6 with questionnaires answered by parents, teachers and children. Results. Growth-Mixture-Modeling yielded five trajectories of irritability levels for the whole sample (high-persistent 3.5 %, decreasing 3.8 %, increasing 2.6 %, low-persistent 44.1 % and null 46.0 %). Among the children who presented with ODD during preschool age, three trajectories of irritability symptoms resulted (high-persistent 31.9 %, decreasing 34.9 % and increasing 33.2 %). Null, low-persistent and decreasing irritability courses in the sample as a whole gave very similar discriminative capacity for children’s psychopathological state at age 6, while the increasing and high-persistent categories involved poorer clinical outcomes than the null course. For ODD children, the high-persistent and increasing trajectories of irritability predicted disruptive behavior disorders, comorbidity, high level of functional impairment, internalizing and externalizing problems and low anger control at age 6. Conclusions. Irritability identifies a subset of ODD children at high risk of poorer longitudinal psychopathological and functional outcomes. It might be clinically relevant to identify this subset of ODD children with a high number of irritability symptoms throughout development with a view to preventing comorbid and future adverse longitudinal outcomes.     

Psychometric Evaluation of the Spiritual Transcendence Scale in a Chinese Sample: Is There Factorial Invariance Across Gender,Occupation, and Religion?

This study investigated the reliability and validity of the widely used 23-item Spiritual Transcendence Scale and tested whether there was factorial invariance of the scale by demographic variables such as gender, occupation, and religion in a large Chinese sample (n = 1,894). Exploratory factor analysis with a random subsample supported the original 3-factor structure (prayer fulfillment, universality, and connectedness) in a revised 16-item scale. Confirmatory factor analysis suggested that a 15-item model provided a good fit to the data of the remaining subsample. The scale had alpha reliabilities ranging from .64 to .92 in the exploratory factor analysis and .60 to .92 in the confirmatory factor analysis. Subsequent factorial invariance tests indicated that the scale was invariant across gender and occupation but not religion. Evidence of construct validity was equivocal. Additional empirical studies should be conducted to evaluate the psychometric properties of the scale in other culturally and religiously diverse settings.     

Examining Identity Styles and Religiosity Among Chilean Undergraduate Students

This study tested Berzsonky’s theory of identity styles and identity commitment in predicting religiosity. Participants were university students (N?=?320) from Chile who were surveyed with the ISI-3 and BRS-6 instruments to measure identity styles and religiosity. Path analysis was used to test the model, which suggested that the three identity styles all had direct effects on commitment. Commitment, in turn, had a direct effect on religiosity. Results revealed that normative, informational, and diffuse-avoidant styles had direct effects on identity commitment, with commitment having a direct effect on religiosity. Also, normative style was shown to have a direct effect on religiosity. Overall, results indicated that commitment is key in explaining religiosity from the perspective of Berzonsky’s theory.     

Adolescents and handheld advertising: The roles of brand familiarity and smartphone attachment in the processing of mobile advergames

Many adolescents are inseparable from their smartphones on which they are often confronted with covert advertising‐like mobile advergames. This study explores the roles of brand familiarity and smartphone attachment in adolescents’ abilities to recognize the commercial intent of advergames. Moreover, it considers the potential indirect effects of brand familiarity and smartphone attachment on the susceptibility of young consumers to mobile advergames. An experiment (N = 98) was conducted, which showed that brand familiarity moderates the effect of playing advergames on the recognition of the commercial intent of advergames. Furthermore, smartphone attachment was found to facilitate the recognition of the commercial intent of advergames, such that adolescents who experienced higher levels of smartphone attachment (when compared to lower levels) were better able to differentiate between advergames and non‐commercial games (games without advertising). Interestingly, no association between smartphone attachment and brand responses were found—suggesting that smartphone attachment did not affect adolescents’ compliance with the advertised message.     

Parent-early adolescent relationship quality and problem behavior in Hungary,the Netherlands,India, and Iceland

Higher parent-child relationship quality has been associated with less internalizing and externalizing problem behavior. However, it remained less clear whether these associations are universal or depend on the country under investigation. Furthermore, fathers are still understudied, even though there is increasing evidence of their important role in early adolescent development. Our study compared the association of mother-child as well as father-child relationship quality with early adolescents’ problem behavior in four culturally different countries, namely Hungary (N = 293; M_age = 11.22; 53% boys), the Netherlands (N = 242; M_age = 11.20; 48% boys), India (N = 230; M_age = 10.68; 61% boys), and Iceland (N = 261; M_age = 10.90; 53% boys). Early adolescents filled out questionnaires in their classroom, assessing warmth and conflict with fathers and mothers and internalizing and externalizing problem behavior. Stepwise multi-group path analysis demonstrated no cross-cultural differences in associations between quality of the parent-child relationship and problem behavior. We did not find any effects of maternal or paternal warmth. However, across samples conflict with mothers was associated with more internalizing and externalizing problem behavior, and conflict with fathers was associated with more externalizing problem behavior. Our findings highlight the need to target conflict with both fathers and mothers in interventions across different countries, especially when addressing externalizing problem behavior.     

Posture and the emergence of manual skills

In this paper, we examine how infants’ natural manual and postural activities — what they prefer and do week by week — are related to developmental transitions in reaching skill and its neuromuscular control. Using a dense, longitudinal design, we tracked the manual and postural activities of four infants in a natural, free‐play setting across the first year of life, and related these activities to two transitions in reaching as measured in a structured laboratory setting: the transition to reaching and the transition to stable reaching. Our data indicated that specific advances in the free‐play setting preceded both transitions. Head and upper torso control, the ability to extend the arm and hand to a distant target, and the ability to touch and grasp objects placed nearby were all precursors to the onset of reaching, whereas sitting independently was associated with the transition to stable reaching. We also found important individual variability in when these ‘components’ were in place, indicating that it is the ensemble of components that is essential, not the order in which they develop or the timing of their contribution. These findings suggest that subsequent experimental manipulations should be planned with respect to infants’ individual constellations of skills, rather than looking at only a single precursor to change.     

Breakdowns in flexible use of information: Intelligence-related differences in transfer following equivalent learning performance

Groups of retarded and nonretarded children were investigated as they learned three rules underlying problems adapted from the Raven Progressive Matrices Test: rotation, imposition, and subtration. The interest was in evaluating group differences in the ease with which the original set of rules was learned and the flexibility with which these rules were transferred to modified contexts. In the case of either learning or transfer, the metric of performance was the amount of aid, specifically the number of computer-generated graduated hints, needed for each subject to solve the problems. The groups were matched on their entering competence to deal with the rules under scrutiny, and also on mental age. No group differences were obtained as the subjects learned the original set of rules. However, on subsequent occasions when required to make flexible use of those rules, clear group differences emerged; and those differences increased as the similarity of the training and test contexts decreased. The results were seen as consistent with theories that emphasize transfer flexibility as one potential source of individual and comparative differences in intelligence.
