Influenceability of Sex Differences under Conditions of Risk Taking

In an experiment on the effect of intensity accents on the perception of time intervals between tones. H. G. Tekman (2001) found that the regular placement of deviant time intervals in short sequences of tones reduced detection, especially if intensity accents marked the deviant time intervals. That was the opposite of what one wòuld have expected on the basis of the dynamic attending theory of M. R. Jones (1976). The effect might have occurred because temporally deviant tones create cumulative onset shifts that affect all the subsequent tones. If the deviations were randomly placed, then they could follow each other in close succession and change the local tempo. In the present study, the changes of local tempo, which might have acted as a cue for the detection of temporal deviations in the random sequences, were eliminated by compensating for deviant time intervals with equal deviations in the opposite direction in the interval that followed. That change in the stimuli eliminated the negative main effect of regularity, and the accenting interacted with regularity in favor of detection in the regular sequences. However, a simple advantage of regular over random sequences was not observed. The author discusses possible reasons for the lack of a facilitatory effect of regularity.     

An Empirical Comparison of Audition,Vision, and Touch in the Discrimination of Temporal Patterns and Ability to Reproduce them

Two conditional reasoning tests were administered to 34 students (17 males and 17 females) at each of four grade levels (i.e., 5th, 6th, 7th, and 8th). Both tests contained conditional reasoning arguments which assessed students' comprehension of five basic principles of inference. However, they varied systematically according to the sex typing of the content (i.e., masculine or feminine). The results indicated that there were no significant sex differences according to grade level, type of content, or principle of inference. On the other hand, at each grade level, there were consistent differences among the mean scores for the five principles, and valid principles were significantly easier than invalid principles. The implications of these findings for future research were discussed.     

Moral Motivation Based on Multiple Developmental Structures: An Exploration of Cognitive and Emotional Dynamics

Intrapersonal variability and multiplicity in the complexity of moral motivation were examined from Dynamic Systems and Self-Determination Theory perspectives. L. Kohlberg's (1969) stages of moral development are reconceptualized as soft-assembled and dynamically transformable process structures of motivation that may operate simultaneously within person in different degrees. Moral motivation is conceptualized as the real-time process of self-organization of cognitive and emotional dynamics out of which moral judgment and action emerge. A detailed inquiry into intrapersonal variation in moral motivation is carried out based on the differential operation of multiple motivational structures. A total of 74 high school students and 97 college students participated in the study by completing a new questionnaire, involving 3 different hypothetical moral judgments. As hypothesized, findings revealed significant multiplicity in the within-person operation of developmental stage structures, and intrapersonal variability in the degrees to which stages were used. Developmental patterns were found in terms of different distributions of multiple stages between high school and college samples, as well as the association between age and overall motivation scores. Differential relations of specific emotions to moral motivation revealed and confirmed the value of differentiating multiple emotions. Implications of the present theoretical perspective and the findings for understanding the complexity of moral judgment and motivation are discussed.     

Interlimb Coordination: Real Constraints and False Dichotomies

Despite the recent advances in the field of coordination dynamics addressing the interplay of constraints of different natures in the emergence of human coordination, F. Mechsner (2004) invites us to revive hierarchical and dichotomous thinking by offering again his exclusive position that coordinated movements are (purely) perceptual-cognitive/psychological in nature. In this comment, the authors address a number of theoretical and methodological issues that might potentially puzzle the readers of Mechsner's article. They contend that the dichotomy proposed by Mechsner (i.e., perceptual-cognitive vs. motor) constitutes a restrictive framework for understanding human coordination.     

Understanding how children's engagement and teachers' interactions combine to predict school readiness

This study examined the quality of preschool classroom experiences through the combination of children's individual patterns of engagement and teachers' classroom-level interactions in predicting children's gains in school readiness. A sample of 605 children and 309 teachers participated. The quality of children's engagement and teacher interactions was directly observed in the classroom, and direct assessments of children's school readiness skills were obtained in the fall and again in the spring. Latent profile analysis was used to examine children's patterns of engagement with teachers, peers, and tasks. Children's engagement and the quality of teacher interactions were associated with gains in school readiness skills. The effect of children's individual classroom engagement on their expressive vocabulary was moderated by classroom-level teacher interactions. The results suggest that when teachers engage in highly responsive interactions across the children in their classrooms, children may develop more equitable school readiness skills regardless of their individual engagement patterns.     

Introduction to the Meta-Structures Project: Prospective Applications

This research project proposes the modeling of collective behaviors such as flocks, industrial districts, and markets. Unlike many other approaches, the aim is to identify ways to recognize, change, and maintain the coherence of collective behaviors, as well as inducing their emergence in configurations of elements that only interact without acquiring properties. The basic assumption is that currently collective behavior is not adequately modeled for the purpose described above when intended as given by sequences of states adopted by the same system over time. Here the sequence of states of a collective behavior in time is considered as corresponding to sequences of different states adopted by systems made up of the same elements interacting with different structures. Sequences of structures are considered to establish meta-structures and their properties correspond to the coherence acquired. The project is based on the use of mesoscopic variables to represent such structural dynamics considered in turn to represent the continuous emergence of coherent collective behavior. Mesoscopic variables are specified and their properties considered as meta-structural properties (properties of sequences of structures). The purpose of this research project is to search for meta-structural properties within processes of computational emergence (computer simulated). I discuss the problem of prescribing meta-structural properties to non-coherent, disordered collective behaviors. I introduce possible approaches for applications to social systems.     

The development of a brief group intervention (Dynamic Interpersonal Therapy) for patients with medically unexplained somatic symptoms: a pilot study

The primary aim of this equivalence study was to compare the outcome of a brief group therapeutic intervention, based on the principles of dynamic interpersonal therapy (DIT) with an intervention based on cognitive behavioural therapy (CBT) in patients suffering from medically unexplained somatic symptoms (MUSS). Participants were 89 patients (aged 18 to 62) who were offered 20 sessions of either DIT or CBT, as central part of a treatment package, consisting of art therapy, psychomotor therapy, social therapy and physical therapy. Measurements were conducted at baseline, 10 weeks and 20 weeks, using self-rating scales measuring the level of anxiety and depression, the severity of medically unexplained symptoms and quality of life. Results showed that CBT and DIT were comparable. The conclusion was that it is recommended to design a larger scale randomised controlled trial to further elaborate the short-term and long-term effects of this novel psychodynamic group therapy for MUSS patients.     

Social support and cardiovascular responding to laboratory stress: Moderating effects of gender role identification,sex, and type of support

The objective of the present study was to examine moderating effects of gender role identification, sex, and type of support on the buffering role of social support on cardiovascular responses. We hypothesized that (a) gender role identification, more than sex, would moderate the effect of social support and (b) to obtain optimal attenuating effects of social support, type of support provided should match type of support preferred in terms of one's gender role identification. That is, feminine participants would benefit more from relatively direct support, whereas masculine participants would benefit more from indirect support. Healthy participants (N = 100) performed a psychological stressor in the presence of a friend, after mental activation of a friend, or alone. Results revealed no moderating effects of gender role identification whether or not in combination with type of support. Nevertheless, results demonstrated an attenuating effect of mental support on heart rate and cardiac output in men. It is concluded that pathways linking social relationships and health may differ between women and men.     

Environmental sound recognition by timbre in children with Williams syndrome

Anecdotal reports have described children with Williams syndrome (WS) as presenting outstanding skills for recognizing environmental sounds by their timbre. This has led to suggest that the skills for environmental sound recognition by timbre are highly developed in WS. Furthermore, the term hypertimbria has been proposed to refer to this feature. However, no academic research has assessed these skills in WS. This study therefore aimed to contrast the reports on the highly developed skills for environmental sound recognition by timbre in children with WS. An environmental sound recognition task was administered to children with WS, children with Down syndrome of the same chronological age and cognitive level, and chronological age-matched typically developing children. Participants with WS performed significantly lower than their typically developing peers and no significant differences were found between the WS and Down syndrome groups. Unlike previous reports, this study points out that in WS environmental sound recognition by timbre does not constitute a phenotypic strength either in absolute or relative terms. Results suggest that children with WS do not present hypertimbria or preserved skills for timbre recognition. We discuss the implications of these results for theories of cognitive modularity.
