Intensive quantities: Why they matter to developmental research

A distinction can be drawn between extensive and intensive quantities. Extensive quantities (e.g., volume, distance), which have been the focus of developmental research, depend upon additive combination. Intensive quantities (e.g., density, speed), which have been relatively neglected, derive from proportional relations between variables. Thus, while proportional relations can be expressed with extensive quantities, these relations are constitutive with intensive quantities. One consequence is that factors, which are theorized as marginal with extensive quantities, are conceptually central in intensive contexts, and may need to be recognized in developmental models. Two such factors, termed variable salience and relational focus, are examined here, via a study where 963 Scottish children aged 7–12 years were asked to solve 42 intensive quantity problems in comparison and missing value format. Reasoning improved with age, but at all ages it was strongly influenced by variable salience and relational focus. Moreover, the manner in which these two factors interacted with other factors differed from what might be expected from models of proportional reasoning with extensive quantities. Based upon these results, it is argued that the distinction between extensive and intensive quantities is theoretically significant, and intensive quantities need to be granted more attention in the future.     

Metrical perception of trisyllabic speech rhythms

The perception of duration-based syllabic rhythm was examined within a metrical framework. Participants assessed the duration patterns of four-syllable phrases set within the stress structure XxxX (an Abercrombian trisyllabic foot). Using on-screen sliders, participants created percussive sequences that imitated speech rhythms and analogous non-speech monotone rhythms. There was a tendency to equalize the interval durations for speech stimuli but not for non-speech. Despite the perceptual regularization of syllable durations, different speech phrases were conceived in various rhythmic configurations, pointing to a diversity of perceived meters in speech. In addition, imitations of speech stimuli showed more variability than those of non-speech. Rhythmically skilled listeners exhibited lower variability and were more consistent with vowel-centric estimates when assessing speech stimuli. These findings enable new connections between meter- and duration-based models of speech rhythm perception.     

Gender‐typing of leadership: Evaluations of real and ideal managers

This research focuses on female underrepresentation in managerial positions. Specifically, two studies examine gender‐typing for managerial roles in Spain using ratings for real and ideal managers. In addition, we analyse the existence of same‐gender bias on evaluations of the behavior of actual leaders. In the first study, 195 Spanish workers evaluate the extent to which gender‐stereotypical traits are important for becoming a successful middle manager in three conditions (female managers, male managers, and managers in general). In the second study, we explore the degree to which the behavior of real Spanish managers is gender‐typed and the existence of same‐gender bias on leadership styles – transformational, transactional and avoidant/passive – and on leadership outcomes – effectiveness, extra effort and satisfaction – from the perspective of subordinates (N = 605). Overall, the results demonstrate that masculine characteristics were rated as more important than feminine characteristics for managerial positions, and they were more often assigned to male managers than to female managers. Unexpectedly, this manager‐male association is stronger among female participants than among male participants. Our findings also demonstrate that women subordinates evaluate their same‐sex supervisors more favorably in transformational leadership, effectiveness, and extra effort. The negative consequences derived from gender‐typing managerial positions are highlighted according to the role congruity theory of prejudice toward female leaders. The positive effects of in‐group female bias on behavior ratings are also noted. The mixed implications of these results for women's advancement to leadership positions are discussed.     

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.     

Examining the influence of anecdotal stories and the interplay of individual differences on reasoning

In two experiments, we explored whether anecdotal stories influenced how individuals reasoned when evaluating scientific news articles. We additionally considered the role of education level and thinking dispositions on reasoning. Participants evaluated eight scientific news articles that drew questionable interpretations from the evidence. Overall, anecdotal stories decreased the ability to reason scientifically even when controlling for education level and thinking dispositions. Additionally, we found that article length was related to participants' ratings of the news articles. Our study demonstrates that anecdotes can discourage scientific reasoning while also pointing to the potential influence of article length on judgements of quality.     

Characterising the Personality of the Public Safety Offender and Non‐offender using Decision Trees: The Case of Colombia

The aim of this paper was to create a decision tree (DT) to identify personality profiles of offenders against public safety. A technique meeting this requirement was proposed that uses the C4.5 algorithm to derive decision rules for personality profiling of public safety offenders. The Mini‐Mult test was used to measure the personality profiles of 238 individuals. With the test results as our database, a C4.5 DT was applied to construct rules that classify each profile into one of two groups, those without and those with records of offences against public safety. The model correctly classified 80% of the personality profiles and delivered a set of decision rules for distinguishing the profiles by group, and the principal personality profiles were interpreted. We conclude that DTs are a promising technique for analysing personality profiles by their offender or non‐offender status. Finally, we believe that the development of a classifying model using DT may have practical applications in the Colombian prison system. Copyright © 2016 John Wiley & Sons, Ltd.     

Life Design Counseling: A study on client's operations for meaning construction

This study evaluated the adequacy of the micro-theory of client operations to explain meaning construction during Life Design Counseling. Four adolescents were interviewed about their second counseling session. Their recollections were stimulated through the replay of counseling videotapes. The resulting transcribed interviews were qualitatively analyzed. Results confirmed a sequence of client operations evolving from the symbolic representation of experience and reflexive self-examination towards making new realizations and revisioning self. Moreover, clients reported negative and positive session moments evidencing that clients' attention and activity during the session was not restricted to meaning construction operations. Practical implications for life design counseling are derived from the results and discussed.     

A Postcolonial Framework for Justification and Eco‐Justice

This work proposes a relationship between eco‐justice and justification by grace rooted in a phenomenological approach. The reality of structural sin experienced by persons living in economic poverty on the African continent is interpreted through the lens of Lutheran catechetical ethics. Lives of repentance will lead to incarnational interventions striving for concrete social transformation.
