Analysis of the Impact of Creative Technique on the Motivation of Physical Education Students in Dance Content: Gender Differences

The aim of this study was to learn about the effectiveness of two dance teaching techniques, the creative examination technique and the direct instruction technique, on the satisfaction of basic psychological needs, the level of self‐determination, the perception of usefulness, enjoyment and effort of physical education students. Likewise, it purports to analyze the gender difference in the psychological variables addressed in agreement with the teaching technique used, to guide and personalize the treatment of these contents in physical education. A quasi‐experimental design was carried out with four natural groups from two school centers. The direct instruction technique was applied with two groups and the creative examination technique with the other two, in a total of 12 sessions. An initial and final measurement was taken in both groups, and the results revealed the complexity to motivate students after 12 sessions. However, the gender‐dependent analyses offer methodological guidelines, as the creative technique causes adaptative consequences on the male gender and disadaptative consequences on the female gender. By way of conclusion, we can highlight the need to devote more sessions to dance teaching and to apply different treatments depending on the gender.     

A Recursive Partitioning Method for the Prediction of Preference Rankings Based Upon Kemeny Distances

Preference rankings usually depend on the characteristics of both the individuals judging a set of objects and the objects being judged. This topic has been handled in the literature with log-linear representations of the generalized Bradley-Terry model and, recently, with distance-based tree models for rankings. A limitation of these approaches is that they only work with full rankings or with a pre-specified pattern governing the presence of ties, and/or they are based on quite strict distributional assumptions. To overcome these limitations, we propose a new prediction tree method for ranking data that is totally distribution-free. It combines Kemeny’s axiomatic approach to define a unique distance between rankings with the CART approach to find a stable prediction tree. Furthermore, our method is not limited by any particular design of the pattern of ties. The method is evaluated in an extensive full-factorial Monte Carlo study with a new simulation design.     

The Relation of Pro‐Sociality to Self‐Esteem: The Mediational Role of Quality of Friendships

The present longitudinal study examined the role of quality of friendship in mediating the relation of pro‐sociality to self‐esteem over time. Participants were 424 Italian young adults (56% females) assessed at two waves (M_age = 21.1 at Time 1; M_age = 25 at Time 2). An autoregressive cross‐lagged panel model was used to test the mediational model. Self‐ and friend‐report measures of pro‐sociality, quality of friendship, and self‐esteem were included in the analyses. Results were in line with the hypothesized paths, with quality of friendship mediating the relation of pro‐sociality to later self‐esteem above and beyond its high stability. Self‐esteem, in turn, predicted pro‐sociality 4 years later. Overall, the present findings support the potential benefits of behaving pro‐socially for an actor in terms of increased perceived self‐worth and also expand previous work by outlining the specific mediational role of the quality of friendships. The theoretical and practical implications of these results are discussed.     

Mistakes pertaining to undesired (relative to desired) self-standards elicit immediate enhanced electrocortical signals of error processing

Past research provides initial evidence that errors pertaining to undesired (vs. desired) self-standards are of greater motivational significance, but little is known about how quickly people recognize and respond to such errors. To examine immediate responses to errors pertaining to desired and undesired self-standards, we assessed event-related potentials (ERPs) while participants judged self-attributes as personally desirable or undesirable. No discernible differences emerged in ERPs associated with correct responses to undesired compared to desired self-standards. Error-related negativities, shown in past work to index motivational significance, and error positivities, shown in past work to index post-error adjustment, were more pronounced when participants erroneously endorsed undesirable self-standards than when they erroneously failed to endorse desirable self-standards. These electrophysiological correlates of differences in the motivational significance of undesired versus desired self-standards emerged within 400 ms of making an error, suggesting that the impact of these errors does not require extensive deliberation.     

Is There a Philosophy of Information?

In 2002, Luciano Floridi published a paper called What is the Philosophy of Information?, where he argues for a new paradigm in philosophical research. To what extent should his proposal be accepted? Is the Philosophy of Information actually a new paradigm, in the Kuhninan sense, in Philosophy? Or is it only a new branch of Epistemology? In our discussion we will argue in defense of Floridi’s proposal. We believe that Philosophy of Information has the types of features had by other areas already acknowledge as authentic in Philosophy. By way of an analogical argument we will argue that since Philosophy of Information has its own topics, method and problems it would be counter-intuitive not to accept it as a new philosophical area. To strengthen our position we present and discuss main topics of Philosophy of Information.     

The relationship between personality organization and sexual life in a community sample of men

Contemporary object-relation theory of personality postulates that the level of severity of personality organization parallels the nature and extent of problems in the patient’s sexual life. The study aims at exploring the relationship between dimensions of Borderline Personality Organization (BPO) (as assessed according to Otto Kernberg’s model), sexual functioning, quality of sexual life and paraphilias in a community sample of men. One-hundred and thirty-six healthy men were asked to complete a set of questionnaires including the Inventory of Personality Organization (IPO), the International Index of Erectile Function, the Sexual Quality of Life Questionnaire, and a checklist to assess the prevalence of paraphilias. High scores on IPO subscales were significantly associated with low overall satisfaction in sexual functioning, low quality of sexual life, and the presence of paraphilias. Results expand previous findings on the relationship between features of BPO and core components of sexual life and support the need for an assessment of personality functioning in subjects reporting sexual problems.     

The Conner’s Adult ADHD Rating Scales-Long Self-Report and Observer Forms: Validation of the Catalan Version

Assessment and diagnosis of adult attention deficit/hyperactivity disorder (ADHD) is complex, involving multiple tasks and several sources of information. The suitability of the instruments needs to be tested in the cultural context in which they will be applied. This study validates the Catalan adaptation of the Conners Adult ADHD Rating Scales-Long Version (CAARS: L), in both its self-report and observer forms. The sample comprised 606 participants. Confirmatory factor analysis was used to test the dimensional structure. Reliability was analysed in terms of internal consistency, test-retest and informant agreement. Age and gender differences were studied, and differential item functioning (DIF) in relation to these variables was tested. Results show that the four-factor model (i.e., Inattention/Memory Problems, Hyperactivity/Restlessness, Impulsivity/Emotional Lability, and Problems with Self-Concept), similar to the original version, presented an adequate fit for both forms. Internal consistency and test-retest correlations reached very high values for the two forms, and informant agreement was high at both test and retest. There were significant gender and age differences that were not due to bias in the measurement instrument, since no item showed differential behaviour with respect to these two variables. The Catalan versions of the CAARS: L present adequate validity and reliability, and they can therefore be used for diagnostic purposes and cross-cultural comparisons.     

Evaluating the temporal structure and correlates of daily self-esteem using a trait state error framework (TSE)

This study evaluates the temporal structure of daily self-esteem and the relative contribution of a range of theoretically motivated predictors of daily self-esteem. To assess self-esteem stability, a daily version of the Rosenberg Self-Esteem scale (RSE, Rosenberg, 1965) was administered to 278 undergraduates for five consecutive days. These short-term longitudinal data were analysed using the Trait State Error (TSE) modelling framework. The TSE decomposes multi-wave data into three components: (1) a stable trait component, (2) a state component, and (3) an error component. Significant predictors of the trait component of self-esteem observed across five days were: (1) emotional stability, and (2) the congruence between implicit and explicit self-esteem. Significant predictors of the state components of self-esteem were daily positive and negative events. We discuss the implications of these results for future research concerning self-esteem stability.

Population Thinking in Epistemic Evolution: Bridging Cultural Evolution and the Philosophy of Science

Researchers in cultural evolutionary theory (CET) have recently proposed the foundation of a new field of research in cultural evolution named ‘epistemic evolution’. Drawing on evolutionary epistemology’s early studies, this programme aims to study science as an evolutionary cultural process. The paper discusses the way CET’s study of science can contribute to the philosophical debate and, vice versa, how the philosophy of science can benefit from the adoption of a cultural evolutionary perspective. Here, I argue that CET’s main contribution to an evolutionary model of scientific growth comes from the application of ‘population thinking’ to science. Populationism offers a ‘variation based’ understanding of scientists’ epistemic and socio-epistemic criteria that is able to better accommodate the variegated preferences that intervene in scientific epistemic decisions. A discussion of the so called theory choice context is offered as an example of the way a populationist approach can shed new light on the operation of scientists’ epistemic choices.
