Age-related Changes in Postural Sway During Sit-to-stand in Typical Children and Children with Cerebral Palsy

Objective: To assess age-related changes in postural sway during sit-to-stand (STS) in typical children (TC) and children with mild cerebral palsy (CP). Methods: Thirty-five TC and 23 children with mild CP were allocated in four different age groups: 5–6, 7–9, 10–12, and 13–15 years; they all performed STS movements over a force plate. Anterior-posterior and medial-lateral amplitude of center of pressure (CoP) displacement, area and velocity of CoP sway were analyzed and compared between the age groups for TC and children with CP. Results: TC at 5 to 6 years of age showed higher values of anterior-posterior CoP displacement and Area of CoP sway than at 10–12 years, during the stabilization phase. There were no age-related changes for CP. Conclusion: TC change their postural sway during the last STS phase over the years, reducing their body sway. Children with CP did not show age-related changes in sway during STS, reflecting a distinct rhythm of postural control development in this population.     

On the Subjectivity of the Experience of Victory: Who Are the Election Winners?

Elections represent key moments in democratic countries, and an established finding from the existing literature is that winners of elections display higher levels of satisfaction with democracy. Yet we know almost nothing about the times when voters feel like winners of an election. Using panel data in four countries, this article finds that while the objective performance of the supported party—measured using vote share and changes in vote share from the previous election—has a very important effect on feeling like an election winner, prior expectations regarding the election’s outcome as well as preferences for the supported party significantly moderate the effect of party performance on voter feelings. It seems also that the identification of the winners and losers of elections are clearer in majoritarian‐style democracies than in proportional systems with coalition governments. Ultimately, the findings indicate that measuring who are the winners of an election using exclusively objective measures of party performance may provide a distorted view of public opinion following the elections.     

Psychological Follow-up of Presymptomatic Genetic Testing for Spinocerebellar Ataxia Type 2 (SCA2) in Cuba

Presymptomatic testing for spinocerebellar ataxia type 2 (SCA2) in Cuba started five years ago. We have now investigated the psychological impact of test results on 150 individuals at 50% risk for SCA2. In a prospective study, psychological instruments were used to evaluate depression, anxiety and family functioning (1) before testing and (2) one year after disclosure of the test result. One year after, anxiety and depression levels decreased both in carriers and non-carriers, but anxiety decreased significantly more in carriers. Pathological levels of anxiety were seen mostly in members of dysfunctional families, but decreased more in them than in other consultands. Presymptomatic testing thus seems to have been especially beneficial for these testees, possibly due to a greater gain from the psychosocial support received. It would be pertinent to evaluate now the impact of other psychosocial variables and perform longer-term longitudinal studies.     

The relationship between search efficiency and crowding

The role of target salience in crowding has remained controversial largely because salience usually escapes objective measurement. Here we address this problem using search efficiency as a measure of target salience. In separate experiments observers determined whether parafoveal arrays of vertical Gabor patterns contained targets having a unique colour, a unique direction of motion, and a unique temporal frequency. We analysed search efficiency in the conventional manner using reaction-time gradients (in seconds per item). We also considered accuracy gradients (in percent-correct per item). Crowding is typically quantified by comparing the acuity for a target within an array to the acuity for a target presented alone. We measured orientation acuity for determining whether a slightly tilted target was clockwise or anticlockwise of vertical. Targets with a unique colour or direction of motion were found to pop out, ie (with one exception) reaction-time and accuracy gradients were insignificantly different from zero. Acuity for these targets was significantly greater than acuity for targets whose neighbours had the same colour and direction of motion. Manipulation of temporal frequency produced a wide range of search efficiencies. For three of four observers we found a linear relationship between acuity and the accuracy gradient, shallow gradients being associated with high acuity. In general, we find that crowding is weakened when observers can find a parafoveally presented target quickly and accurately.     

Ten-year-old girls' and boys' body composition and peer victimization experiences: prospective associations with body satisfaction

This study examined prospective associations between 10-year-olds’ weight and height, their perception of shape and stature, frequent experiences of peer victimization, and different aspects of body esteem at age 13. Participants were 474 girls and 400 boys participating in a two-wave longitudinal questionnaire study. Main results were that whereas actually being heavier built at age 10 was associated with girls’ increments in body dissatisfaction, the mere perception of being too heavy was associated with boys’ poorer body satisfaction. Also, boys who believed that they were too short were more dissatisfied at follow-up. Whereas frequent peer victimization had long-term associations with girls’ weight-esteem, teasing targeted towards appearance was associated with boys’ more negative beliefs about what others think about their appearance. Finally, participants had become significantly more dissatisfied at age 13, suggesting that this is a time in life when both girls and boys risk becoming increasingly critical towards their appearance.     

Dieting behaviors, body shape perceptions, and body satisfaction: cross-cultural differences in Argentinean and Swedish 13-year-olds

This exploratory study represents a cross-cultural effort to examine differences in dieting practices and weight loss attempts, perceived body shape, and body satisfaction between young Argentinean and Swedish adolescents. The study group consisted of 358 Argentinean (193 girls, 165 boys) and 874 Swedish (474 girls, 400 boys) 13-year-olds. A main finding was that Argentinean and Swedish adolescents did not differ on body satisfaction, although girls in both countries displayed greater body dissatisfaction than did boys. Dieting and weight loss attempts were more prevalent among the Argentinean adolescents, especially among girls, and did not appear to depend on overweight or perception of body shape. The samples also differed in their perceptions of body shape and the effect those perceptions had on their body satisfaction, with Swedish adolescents suffering more from negative body shape perceptions.     

Does the nature of the experience influence suggestibility? A study of children's event memory

Two experiments examined the effects of event modality on children's memory and suggestibility. In Experiment 1, 3- and 5-year-old children directly participated in, observed, or listened to a narrative about an event. In an interview immediately after the event, free recall was followed by misleading or leading questions and, in turn, test recall questions. One week later children were reinterviewed. In Experiment 2, 4-year-old children either participated in or listened to a story about an event, either a single time or to a criterion level of learning. Misleading questions were presented either immediately or 1 week after learning, followed by test recall questions. Five-year-old children were more accurate than 3-year-olds and those participating were more accurate than those either observing or listening to a narrative. However, method of assessment, level of event learning, delay to testing, and variables relating to the misled items also influenced the magnitude of misinformation effects.     

Evaluación de la escala de control de la acción

Resumen

El objetivo ele la investigación fue determinar las propiedades psicométricas básicas de la Escala de Control de la Acción de Kuhl en una muesta de estudiantes mexicanos. La escala fue traducida y sometida a varias revisiones por los autores, después de lo cual se aplicó a una muestra de 180 estudiantes universitarios. La confiabilidad alfa de Cronbach de las diferentes subescalas fue baja. Un análisis de componentes principales con rotación ortogonal mostró que el porcentaje de varianza explicada por el primer factor de cada subescala fue muy pequeño. Se intenta explicar los resultados con base en la deficiente caracterización que hace Kubl de las diferentes clases de orientación hacia el estado y factores de tipo cultural.     

Perversion – structure or organization?

Abstract

This paper aims to discuss perversion, its implications in the clinical setting, and some of the key concepts around it. First, the etymology of the words “perversion”, “structure”, and “organization” is analyzed. Next follows a discussion on the sexual organization of instincts – from the Unconscious to the Oedipus complex in Freud and Lacan – setting the ground for a disavowal-based theory of perversion. An instructive approach has been chosen so as better to organize the various points presented.

Laender NR et al. Perversion – Struktur oder Organisation?

Der Aufsatz diskutiert die Perversion, ihre Auswirkungen im klinischen Setting und einige Schlüsselkonzepte. Zuerst wird die Herkunft der Wörter Perversion, Struktur und Organisation analysiert. Dann folgt eine Diskussion über die Organisation der Sexualität bzw. der Instinkte – vom Unbewussten bis zum Ödipuskomplex bei Freud und Lacan – wodurch eine Theorie der Perversion auf der Basis von Ablehnung begründet wird. Ein instruktiver Zugang, bei dem die verschiedenen Punkte von Interesse gut strukturiert sind, wurde gewählt.
