Characterization of speed fluctuation and drag force in young swimmers: A gender comparison

The aim of this study was to compare the speed fluctuation and the drag force in young swimmers between genders. Twenty-three young pubertal swimmers (12 boys and 11 girls) volunteered as subjects. Speed fluctuation was measured using a kinematical mechanical method (i.e., speedo-meter) during a maximal 25-m front crawl bout. Active drag, active drag coefficient and power needed to overcome drag were measured with the velocity perturbation method for another two maximal 25 m front crawl bouts with and without the perturbation device. Passive drag and the passive drag coefficient were estimated using the gliding decay velocity method after a maximal push-off from the wall while being fully immersed. The technique drag index was also assessed as a ratio between active and passive drag. Boys presented meaningfully higher speed fluctuation, active drag, power needed to overcome drag and technique drag index than the girls. There were no significant gender differences for active drag coefficient, passive drag and passive drag coefficient. There were positive and moderate-strong associations between active drag and speed fluctuation when controlling the effects of swim velocity. So, increasing speed fluctuation leads to higher drag force values and those are even higher for boys than for girls.     

Confirmatory Factor Analysis,Reliability, and Validity of a Spanish Version of FACES III

This study tested the properties of a Spanish version of the Family Adaptability and Cohesion Scales III (FACES III) in a Spanish sample. Participants were 632 adults with children attending several school institutions from day care to undergraduate university. Confirmatory factor analyses replicated the factor structure of the original American version. Reliability coefficients were higher for the cohesion ( f = .72) than the adaptability scale ( f = .68). Convergent and discriminant validity was supported through a MTMM approach. The Spanish FACES III seems to be a valid and reliable measure.     

Cognitive Socialization Across Ethnocultural Contexts: Literacy and Cultural Differences in Intellectual Performance and Parent-Child Interaction

A comparative study of parent-child interaction and its relation to children's intellectual achievement is presented. The question of cultural continuities in cognitive development was examined. The cross-national design also illustrates some of the problems encountered when such relationships are studied across social contexts in general. The results suggest that although interaction characteristics are related to children's intellectual achievement, that relation is moderated by context factors that may operate differently in each culture. The findings are discussed in terms of how literacy mediates parents' teaching styles in ways that remain culturally ingrained. Research issues and recommendations for future research and policy are discussed.     

Management Communication and Employee Performance: The Contribution of Perceived Organizational Support

This study used a cross-lagged panel design to examine the temporal relationship between management communication and perceived organizational support (POS), and its consequences for performance. We assessed management communication and POS 2 times, separated by a 3-year interval, in a social services organization (N?=?236). Our findings suggest that management communication was positively associated with a temporal change in POS. In addition, we found that POS fully mediates the relationship between management communication and both in-role and extra-role performance. The present study advances our theoretical knowledge concerning how management communication affects performance, with implications for practice. Specifically, it reveals that management communication affects performance mainly because it signals that the organization cares about the well-being and values the contributions of its employees.     

Working memory and two-digit number processing

The processing of two-digit numbers in comparison tasks involves the activation and manipulation of magnitude information to decide which number is larger. The present study explored the role of different working memory (WM) components and skills in the processing of two-digit numbers by examining the unit–decade compatibility effect with Arabic digits and number words. In the study, the unit–decade compatibility effect and different WM components were evaluated. The results indicated that the unit–decade compatibility effect was associated to specific WM skills depending on the number format (Arabic digits and number words). We discussed the implications of these results for the decomposed view of two-digit numbers.     

Goal Orientation and Work Role Performance: Predicting Adaptive and Proactive Work Role Performance Through Self-Leadership Strategies

This article explores the relationship between goal orientation, self-leadership dimensions, and adaptive and proactive work role performances. The authors hypothesize that learning orientation, in contrast to performance orientation, positively predicts proactive and adaptive work role performances and that this relationship is mediated by self-leadership behavior-focused strategies. It is posited that self-leadership natural reward strategies and thought pattern strategies are expected to moderate this relationship. Workers (N = 108) from a software company participated in this study. As expected, learning orientation did predict adaptive and proactive work role performance. Moreover, in the relationship between learning orientation and proactive work role performance through self-leadership behavior-focused strategies, a moderated mediation effect was found for self-leadership natural reward and thought pattern strategies. In the end, the authors discuss the results and implications are discussed and future research directions are proposed.     

Emotional expressivity in men and women: Stereotypes and self-perceptions

Three studies were conducted to assess prevalent stereotypes regarding men's and women's emotional expressivity as well as self-perceptions of their emotional behaviour. Emotion profiles were employed to assess both modal emotional reactions and secondary emotional reactions to hypothetical events and personal experiences. In Study 1 we asked how men and women in general would react to a series of hypothetical emotional events. In Study 2 we asked how participants themselves expected to react to these same situations and in Study 3 we asked participants to report a personal emotional event in narrative form. Two gender differences emerged across all three studies. Specifically, women were expected to be more likely to react with sadness to negative emotion-eliciting events in general. They also expected themselves to be more likely to react with sadness as well as to cry and to withdraw more when experiencing negative emotional events. Finally, women report more sadness when describing personal events. In contrast, men were expected to react with more happiness/serenity during negative emotional situations. Also, they expect themselves to react more frequently this way as well as to laugh and smile more and to be more relaxed in negative situations. Finally, men tend to report more happiness when describing negative personal events. In sum, the present study gives a more detailed portrayal of how men and women are expected and expect themselves to react to specific emotional situations and presents some evidence that these expectations may influence the way they reconstruct emotional events from their past.     

Facilitated detection of angry faces: Initial orienting and processing efficiency

In a visual search task, displays of four schematic faces (angry, sad, happy, or neutral) were presented. Participants decided whether the faces were all the same or whether one was different. A discrepant angry face in a context of three neutral faces was detected faster than other faces. This occurred in the absence of a higher probability of first fixation on the angry face. Moreover, angry faces were more accurately detected even when presented parafoveally. These results are not consistent with the hypothesis that angry faces are detected faster because they are looked at earlier. In contrast, angry faces were looked at less than other faces during the search process and were more accurately detected than other faces when the display duration was reduced to 150 ms. These results support the processing efficiency hypothesis, according to which fewer attentional resources are needed to identify angry faces, which would account for their speeded detection time. In addition, parafoveal analysis of the angry faces may start preattentively, which would account for the fewer and shorter fixations that they need later, when they come under the focus of attention.     

Spatial location and emotion modulate voice perception

ABSTRACT

How do we perceive voices coming from different spatial locations, and how is this affected by emotion? The current study probed the interplay between space and emotion during voice perception. Thirty participants listened to nonverbal vocalizations coming from different locations around the head (left vs. right; front vs. back), and differing in valence (neutral, positive [amusement] or negative [anger]). They were instructed to identify the location of the vocalizations (Experiment 1) and to evaluate their emotional qualities (Experiment 2). Emotion-space interactions were observed, but only in Experiment 1: emotional vocalizations were better localised than neutral ones when they were presented from the back and the right side. In Experiment 2, emotion recognition accuracy was increased for positive vs. negative and neutral vocalizations, and perceived arousal was increased for emotional vs. neutral vocalizations, but this was independent of spatial location. These findings indicate that emotional salience affects how we perceive the spatial location of voices. They additionally suggest that the interaction between spatial (“where”) and emotional (“what”) properties of the voice differs as a function of task.     

The processing of Arabic numbers is under cognitive control

In this study, we evaluated whether the processing of two-digit Arabic numbers is subject to cognitive control. Participants performed a number comparison task with unit–decade compatible trials (36–47) and unit–decade incompatible number pairs (37–46). The unit–decade compatibility (incompatible minus compatible trials) was considered an index of conflict situation in numerical processing. To examine whether participants adapted to numerical conflict, we manipulated the percentage of incompatible trials relative to the percentage of compatible trials (20, 50, 80 % incompatible trials). The unit–decade compatibility effect was modulated by the amount of incompatible trials: the compatibility effect decreased progressively as the percentage of incompatible trials increased. This result indicated that participants adapted to numerical conflict. The findings are discussed in terms of cognitive control. Implications for models of two-digit number processing are also addressed.
