Geographic variation in floral allometry suggests repeated transitions between selfing and outcrossing in a mixed mating plant

• Premise of the study: Isometric and allometric scaling of a conserved floral plan could provide a parsimonious mechanism for rapid and reversible transitions between breeding systems. This scaling may occur during transitions between predominant autogamy and xenogamy, contributing to the maintenance of a stable mixed mating system. • Methods: We compared nine disjunct populations of the polytypic, mixed mating species Oenothera flava (Onagraceae) to two parapatric relatives, the obligately xenogamous species O. acutissima and the mixed mating species O. triloba. We compared floral morphology of all taxa using principal component analysis (PCA) and developmental trajectories of floral organs using ANCOVA homogeneity of slopes. • Key results: The PCA revealed both isometric and allometric scaling of a conserved floral plan. Three principal components (PCs) explained 92.5% of the variation in the three species. PC1 predominantly loaded on measures of floral size and accounts for 36% of the variation. PC2 accounted for 35% of the variation, predominantly in traits that influence pollinator handling. PC3 accounted for 22% of the variation, primarily in anther–stigma distance (herkogamy). During O. flava subsp. taraxacoides development, style elongation was accelerated relative to anthers, resulting in positive herkogamy. During O. flava subsp. flava development, style elongation was decelerated, resulting in zero or negative herkogamy. Of the two populations with intermediate morphology, style elongation was accelerated in one population and decelerated in the other. • Conclusions: Isometric and allometric scaling of floral organs in North American Oenothera section Lavauxia drive variation in breeding system. Multiple developmental paths to intermediate phenotypes support the likelihood of multiple mating system transitions.

Comparison of Reading Development Across Socioeconomic Status in the United States

It is well known that higher parental socioeconomic status (SES) predicts better child reading outcomes, but little work has been done to unpack this finding. The main overall question addressed by this project was whether cognitive models of the two main reading outcomes, single word reading (SWR) and reading comprehension (RC), performed similarly across levels of parental SES. The current study predicted a differential relation between parental SES and both predictors and outcomes because of the known large relation between parental SES and child oral language development. Three questions examined the mediating effects of cognitive predictors on the relation between parental SES and reading outcomes, the moderating effects of SES on the developmental trajectories of reading outcomes, and the strength of the relationship between SES and the two reading outcomes. Participants were part of two large and comprehensive datasets: the cross-sectional Colorado Learning Disability Research Center (CLDRC; n=1554) sample, and the International Longitudinal Twin Study (ILTS; n=463 twin pairs) sample. In terms of cognitive predictors, the relation between SES and SWR was disproportionately mediated by two language skills, vocabulary (VOC) and phonological awareness (PA). For the RC models, both SWR and oral listening comprehension (OLC) did not disproportionally mediate the relation between RC and SES; however, full mediation was not exhibited. With regard to the trajectory of reading outcomes, SES moderated the starting values of SWR and RC, and the slopes of SWR development. When performance on the control measures of early reading skills (e.g., print knowledge, vocabulary, and decoding skills) was included the models, the moderating effects of SES were completely accounted for by these measures. In terms of outcomes, SES had a stronger relation to RC than to SWR, especially at later ages. These findings have implications for interventions aimed at improving reading outcomes in children from lower SES families.

Season-Long Examination of the Intervention Tone of Coach-Athlete Interactions and Athlete Development in Youth Sport

Objectives: Coaches are a primary influence on athletes' development in youth sport (Horn, 2008). However, the intervention tone of coaches' behaviour has not been directly observed. The purpose of this study was to examine associations between the intervention tone exhibited by youth sport coaches and athletes' individual developmental trajectories over the course of a season. Design: Short-term longitudinal study with behavioural observation. Method: Fifty-five athletes and their coaches from five youth volleyball teams were observed at three time points, and the intervention tone of interactive behaviour was systematically coded and organized by coach-athlete dyad. Athletes completed measures of the 4C's of athlete development (competence, confidence, connection, character) at each time point, which were used to create individualized developmental trajectories. Person-centred analyses were used to examine associations between athletes' developmental trajectories and their unique interactive experiences with their coach. Results: Cluster analysis revealed the presence of three distinct clusters based on athletes' developmental trajectories: 1) high and increasing, 2) low and decreasing, and 3) moderate and maintaining, with athletes from each team distributed across clusters. Analysis of dyadic interaction profiles revealed significant differences in interactive behaviour between clusters. Conclusions: Results suggest that differences in coach-athlete interactive experiences are associated with different developmental trajectories over the course of a season, even for athletes working with the same coach, highlighting the individualized nature of coaches' influence on young athletes. Practical implications for coaches include a critical awareness of their unique interactive relationship with each athlete independently, as well as the importance of fostering these relationships with regard to young people as more than just athletes.

Corrélats neuronaux du circuit des récompenses chez les jeunes à risque parental de troubles de l'humeur

Cette thèse a pour objectif l’investigation du circuit des récompenses, sur les plans comportementaux et neuronaux, chez des adolescents à risque parental élevé de dépression majeure et de trouble bipolaire, en comparaison à des jeunes à risque parental peu élevé. Plus précisément, le but est d’identifier des marqueurs comportementaux et neuronaux du risque de développer une dépression majeure ou un trouble bipolaire, afin d’être en mesure de détecter et de prévenir ces troubles le plus tôt possible pour éviter, ou du moins retarder, leur émergence. Pour ce faire, nous avons réalisé deux études, présentées ici dans deux articles empiriques. Dans le premier article, le fonctionnement comportemental et neuronal du circuit des récompenses a été investigué au moyen d’une tâche d’anticipation et d’obtention de gains et de pertes monétaires, chez des adolescents à risque parental de dépression majeure (i.e., jeunes asymptomatiques dont un des parents souffre de dépression majeure), des adolescents à risque parental de trouble bipolaire (i.e., jeunes asymptomatiques dont un des parents souffre de trouble bipolaire) et des adolescents contrôles (i.e., jeunes asymptomatiques dont les deux parents sont en bonne santé mentale). Au niveau comportemental, les résultats ont révélé une meilleure performance chez les jeunes à risque de dépression majeure lorsqu’ils devaient éviter d’obtenir des pertes monétaires de magnitude variée (0,20$, 1$ ou 5$), ainsi qu’une meilleure performance chez les jeunes à risque de trouble bipolaire sur les essais impliquant d’éviter des pertes monétaires de magnitude nulle (0$). Au niveau neuronal, les jeunes à risque de dépression majeure démontraient une diminution de l’activation du cortex préfrontal dorsolatéral lors de l’anticipation de potentielles pertes monétaires de magnitude variée, tandis que les jeunes à risque de trouble bipolaire démontraient une diminution de l’activation du cortex préfrontal dorsolatéral lors de l’anticipation de potentielles pertes monétaires de magnitude nulle. De plus, les jeunes à risque de dépression majeure tendaient à démontrer une augmentation de l’activité du cortex orbitofrontal durant l’évitement réussi de pertes monétaires, tandis que les jeunes à risque de trouble bipolaire tendaient à démontrer une augmentation de l’activité du cortex orbitofrontal lors de l’obtention de pertes monétaires. Dans le deuxième article, l’intégrité structurelle des régions fronto-limbiques a été investiguée, au moyen de mesures du volume, de l’épaisseur corticale et de la superficie corticale. Les résultats ont mis en évidence, chez les jeunes à risque de trouble bipolaire, un volume plus élevé du cortex préfrontal dorsolatéral, par rapport aux jeunes à risque de dépression majeure et contrôles. De plus, les jeunes à risque de trouble bipolaire présentaient un volume plus élevé du cortex cingulaire postérieur, en comparaison aux jeunes à risque de dépression majeure. Enfin, une diminution de l’épaisseur corticale du cortex orbitofrontal et du gyrus frontal moyen a été observée chez les adolescents à risque de trouble bipolaire, en comparaison au groupe contrôle. L’ensemble de ces résultats démontre ainsi l’existence de particularités comportementales et d’altérations neuronales sur les plans fonctionnel et structurel, chez des jeunes à risque élevé de troubles de l’humeur, et ce, avant même l’émergence des premiers symptômes thymiques. Plus particulièrement, ces caractéristiques pourraient constituer des marqueurs du risque de développer un trouble de l’humeur. Par conséquent, ces marqueurs pourraient aider à mieux identifier les jeunes qui sont le plus à risque de développer un trouble de l’humeur, et ainsi permettre la mise en place précoce de stratégies préventives adaptées, afin d’éviter des trajectoires développementales psychopathologiques.

Pretend play, mirror self-recognition and imitation: A longitudinal investigation through the second year

The aim in the current study was to investigate the emergence of pretend play, mirror self-recognition, synchronic imitation and deferred imitation in normally developing human infants. A longitudinal study was conducted with 98 infants seen at three-monthly intervals from 12 through to 24 months of age. At each session the infants were tested on a range of tasks assessing the four target skills. Deferred imitation was found to emerge prior to synchronic imitation, pretend play and mirror self-recognition. In contrast, the latter three skills emerged between 18 and 21 months and followed similar developmental trajectories. Deferred imitation was found to hold a prerequisite relation with these three skills. Synchronic imitation, pretend play and mirror self-recognition were not closely associated and no prerequisite relations were found between these skills. These findings are discussed in the context of current theories regarding the development of pretend play, mirror self-recognition, synchronic imitation and deferred imitation in the second year.

Toddlers' prosocial behavior: from instrumental to empathic to altruistic helping.

The study explored how the meaning of prosocial behavior changes over toddlerhood. Sixty-five 18- and 30-month-olds could help an adult in 3 contexts: instrumental (action based), empathic (emotion based), and altruistic (costly). Children at both ages helped readily in instrumental tasks. For 18-month-olds, empathic helping was significantly more difficult than instrumental helping and required greater communication from the adult about her needs. Altruistic helping, which involved giving up an object of the child's own, was the most difficult for children at both ages. Findings suggest that over the 2nd year of life, prosocial behavior develops from relying on action understanding and explicit communications to understanding others' emotions from subtle cues. Developmental trajectories of social-cognitive and motivational components of early helping are discussed.

A Vinculação e a Auto-Estima em Jovens Não-Institucionalizados Vs. Institucionalizados

Introdução: Uma relação de vinculação segura implica a presença de um modelo representacional das figuras de vinculação como “disponíveis” e capazes de proporcionar protecção e que a qualidade dos cuidados parentais precoce é fundamental a determinar a saúde mental dos indivíduos. Se esta relação assume um enorme relevância para a saúde mental de qualquer ser humano, a institucionalização de crianças/jovens, envolvendo ameaças em termos da disponibilidade das figuras de vinculação constitui uma condição propícia para atrasos de desenvolvimento e aumento da probabilidade do desenvolvimento de sintomatologia psicopatológica. Os objectivos deste estudo passam, então, por analisar as diferenças na vinculação, mas também na auto-estima, de jovens institucionalizados vs nãoinstitucionalizados. Metodologia: A nossa amostra é constituída por 223 jovens nãoinstitucionalizados de duas escolas do Concelho de Coimbra (média de idades M=15.3; desvio-padrão, DP=1.97) e 47 jovens institucionalizados (M=15.5 DP=1.93). Tanto os jovens institucionalizados como não-institucionalizados preencheram um questionário com questões sóciodemográficas, relacionais, escolares, de saúde e bem-estar (com pequenas particularidades em algumas variáveis conforme a sub-amostra), o Inventory of Parent Attachment (IPPA) e a Rosenberg Self-Esteem Scale (RSES). A sub-amostra de jovens institucionalizados respondeu ainda a questões sobre a sua adaptação/vivência ao/no Lar. Resultados: Os rapazes da amostra não institucionalizada apresentam uma pontuação média mais elevada de auto-estima vs. raparigas. Nos jovens institucionalizados não foram encontradas diferenças de género a este nível. Não existem diferenças de género, em ambas as sub-amostras, na pontuação total do IPPA e suas dimensões. Os rapazes nãoinstitucionalizados vs. institucionalizados não divergem na pontuação média total de autoestima. O mesmo sucede com as raparigas. Ambas as sub-amostras não divergem na pontuação média total do IPPA e suas dimensões. Na amostra não-institucionalizada quer nos rapazes, quer nas raparigas não existem diferenças na pontuação total média na RSES, entre os jovens mais novos vs. mais velhos. Na amostra institucionalizada também não se verificam diferenças na pontuação total na RSES por idades. Nos jovens não institucionalizados foram encontradas diferenças na pontuação total média no IPPA (e suas dimensões, à excepção da Alienação), por idade, com os mais novos a apresentarem sempre valores médios mais elevados. Na amostra institucionalizada estas diferenças não se verificaram. Nos rapazes e raparigas da amostra não-institucionalizada verificaram-se associações significativas entre a pontuação na RSES e no IPPA e em todas as suas dimensões. O mesmo se verificou na subamostra institucionalizada. Não existe uma associação significativa entre a pertença a dada sub-amostra e a pertença ao grupo “pouco seguro” vs. “muito seguro”. Apesar de outras associações terem sido encontradas, importa reforçar as associações significativas entre a pontuação na auto-estima e na vinculação total e suas dimensões (quer nos rapazes e raparigas não-institucionalizados, como na amostra institucionalizada) e variáveis como a sintomatologia depressiva, a sintomatologia ansiosa e algumas variáveis relacionais. Discussão/Conclusão: De um modo geral parecem não existir diferenças entre jovens nãoinstitucionalizados vs. institucionalizados em termos de vinculação e de auto-estima. Porém, a uma vinculação insegura e uma menor auto-estima associam-se piores outcomes (e.g. sintomatologia depressiva) em ambas as amostras. Os profissionais trabalhando com adolescentes não-institucionalizados ou institucionalizados devem preocupar-se em avaliar a sua auto-estima e vinculação, procurando, eventualmente, nelas intervir terapeuticamente. / Introduction: It is well kown that a secure attachment relation implies the presence of representational model of the attachment figures as being available and able to provide protection and that the quality of earlier parental care is crucial in determining subjects mental health and there developmental trajectories. If this relation assumes such a big relevance to the mental health of any human being, the institutionalization of children/adolescents, even when truly needed, involving threats in terms of the availability of attachment figures constitutes a condition that might lead to developmental delays and might increase the probability of psychopathological sintomatology developing. The aims of this study are, then, to analyze if there are attachment differences and, also, in self-esteem, between a sub-sample of non-institutionalized and institutionalized adolescents. Methodology: Our sample comprises 223 adolescents non-institutionalized from two schools of Coimbra Council (mean age, M=15.3; standard deviation, SD=1.97) and 47 institutionalized adolescents (M=15.5 SD=1.93). Both sub-samples filled in a questionnaire with sociodemographic, relational, about school, health and well-being questions (with small particularities in some variables, regarding each sub-sample), the Inventory of Parent Attachment (IPPA) and the Rosenberg Self-Esteem Scale (RSES). Institutionalized adolescents also answered questions about the adaptation/life to/in the institution. Results: Boys from the non-institutionalized sub-sample present an higher self-esteem mean score vs. girls. We did not find significant gender differences in self-esteem mean score in the subsample of institutionalized adolescents. There are no gender differences, in both sub-samples, in IPPA (and all its dimensions) total score. Non-institutionalized boys vs. institutionalized boys do not differ in their self-esteem mean score. The same is valid for girls. Both subsamples do not differ in their IPPA (and all its dimensions) mean score. In the noninstitutionalized sample, either in boys, either in girls there are no differences regarding total RSES mean score, between younger (12-15 years old) and older (16-20 years old) adolescents. In the institutionalized sample there were also no differences regarding this score, by age groups. In the non-institutionalized sub-sample we found differences in IPPA total mean score (an in all its dimensions, with the exception of Alienation), by age, with younger adolescents presenting always higher mean scores. In the institutionalized sample there were no differences. Both in boys and girls from the non-institutionalized sample there were significant associations between RSES score and IPPA (and all its dimensions) score. The same result was found in the total institutionalized sample. Although other significant associations were found, we must reinforce the presence of significant associations between self-esteem score and IPPA total score (and of its dimensions) (either in boys and girls noninstitutionalized, either in the institutionalized sub-sample) and variables such as lifetime and depressive symptomatology in the last two weeks, anxious symptomatology in the last two weeks and some relational variables. Discussion/Conclusion: In general, we did not found significant differences between non-institutionalized vs. institutionalized adolescents in terms of attachment and self-esteem. However, a secure attachment and a lower self-esteem are associated with worst outcomes (e.g. depressive symptomatology) in both samples. Professionals working with adolescents, either or not institutionalized must assess their selfesteem and attachment and might, eventually, intervene on these aspects therapeutically.

Viel bringt viel? Effekte lernzeitverlängernder Maßnahmen auf die Lese- und Mathematikleistungen von Grundschülerinnen und Grundschülern mit ungünstiger Lernausgangslage

Der vorliegende Beitrag untersucht die Effekte von lernzeitverlängernden Maßnahmen für Grundschülerinnen und Grundschüler in Mecklenburg-Vorpommern mit einer ungünstigen Lernausgangslage zum Zeitpunkt der Einschulung. Dazu wurde über die gesamte Grundschulzeit hinweg die Leistungsentwicklung von 67 Kindern in den Bereichen Lesen und Rechnen erfasst. Bei 19 Kindern wurde eine Lernzeitverlängerung durch Diagnoseförderklassen (DFK) realisiert, bei 18 durch eine Klassenwiederholung (KW) und 30 Kinder lernten in regulären Grundschulklassen (GSK) ohne eine Lernzeitverlängerung. Die Auswertungen der Daten mittels Hierarchisch-linearer Modelle (HLM) weisen auf gleiche Entwicklungsverläufe der drei Untersuchungsgruppen in den Bereichen Lesen und Mathematik hin. Zum Ende der Klasse 4 erreichten die drei Gruppen ähnliche Leistungsniveaus. In allen drei Settings fiel auf, dass die Entwicklung mathematischer Kompetenzen über die Schulzeit hinweg verzögert erfolgte. Ungünstige Lernausgangslagen im Bereich Mathematik konnten den Analysen zufolge durch keine der untersuchten Beschulungsformen ausreichend kompensiert werden. (DIPF/Orig.)

Risco e regulação emocional em idade pré-escolar: A qualidade das interações dos educadores de infância como potencial moderador

A investigação tem demonstrado que as crianças em desvantagem social enfrentam muitos desafios e estão mais vulneráveis a desenvolver dificuldades ao nível da regulação emocional, sendo extremamente relevante identificar fatores protetores que moderem esta vulnerabilidade, de modo a identificar formas de alterar as trajetórias desenvolvimentais. No presente estudo, foi analisado o papel moderador das interações do educador de infância no desenvolvimento da regulação emocional. Os participantes incluíram 345 crianças em idade pré-escolar de dois ambientes sociais distintos: em risco sociocultural (n=183) e em situação de não risco sociocultural. A regulação emocional foi avaliada através de um questionário ao educador, o Emotion Regulation Checklist (ERC; Shields & Cichetti, 1997). A qualidade das interações do educador de infância com as crianças foi observada através de uma escala de observação, o Classroom Assessment Scoring System (CLASS; Pianta, La Paro & Hamre, 2008). Os educadores avaliaram ainda a sua relação com cada criança participante através da Student-Teacher Rating Scale (STRS; Pianta, 2001). Análises multi-grupo multinível indicaram que no grupo de crianças de risco socicultural, em salas em que os educadores de infância estabeleciam interações com mais qualidade a nível emocional e organizacional, as crianças demonstraram competências de regulação emocional mais elevadas, o que sugere o importante papel das interações dos educadores de infância com as crianças no desenvolvimento da regulação emocional.
