Language-mediated object categorization: A longitudinal study with 16- to 20-month-old Serbian-speaking children

This study addressed the development of language-mediated categorization longitudinally, on a sample of Serbian-speaking children aged 16–20 months. Twenty four children were tested 3 consecutive times on: categorization of unknown objects with a shared label and a similar shape; and categorization of unknown objects with a shared label, but no visual similarity. The task was embedded in a game-like activity which included real object manipulation, categorization of novel objects labeled with made-up names, and socio-pragmatic cues provided by the experimenter. Our results indicate that an average child develops the ability to categorize novel objects with a similar shape and a shared label around 16 months of age, whereas for novel objects with a shared label, but no visual similarity, this ability is acquired sometime between 18 and 20 months of age. Our results partly confirm research findings obtained in other languages, thus emphasizing the need for cross-linguistic and cross-cultural validation of all language-related developmental studies.     

Trust in alternative and professional media: The case of the youth news audiences in three European countries

Abstract

This exploratory paper applying cross-cultural and developmental perspective analyses and discusses trust in alternative media and its relation to trust in professional media, seeking to identify the national specifics of media trust and its developmental patterns. Employing 2016 survey data of Czech, Estonian and Greek youth (aged 14–25, N = 3654) collected as part of the international CATCH-EyoU project (Horizon 2020), the study outlines the typology of media trust, comprising trust in alternative and professional media, and compares social and political predictors influencing media trust in the three countries. The study illustrates the diversity of relations between the two types of media trust, concluding that differences in selected predictors of media trust and the distribution of media trust types across national sub-samples illuminate the strong role national context plays, illustrating the varying pathways development of media trust follows in these varied contexts along socioeconomic and cultural lines.     

Sexting as a predictor of sexual behavior in a sample of Czech adolescents

The purpose of this longitudinal study is to examine the relationship between teen sexting and offline sexual behavior. Using a sample of 1134 Czech adolescents aged 10–18 (M_age = 13.84, SD = 1.94, girls = 58.8%) from 55 schools, the latent growth model of offline sexual behavior with sexting as a time-varying covariate was employed. Participants differed at baseline for offline sexual behavior at both individual and school levels, and they varied in the growth rate of offline sexual behavior at the individual level. Only age and sensation seeking explained the variability at baseline of offline sexual behavior. The positive association between sexting and offline sexual behavior was not constant across time. However, sexting at baseline predicted offline sexual behavior a half year and one year later. Sexting may be treated as a precursor of offline sexual behavior.     

Action‐semantic and syntactic deficits in subjects at risk for Huntington's disease

Frontostriatal networks play critical roles in grounding action semantics and syntactic skills. Indeed, their atrophy distinctively disrupts both domains, as observed in patients with Huntington's disease (HD) and Parkinson's disease, even during early disease stages. However, frontostriatal degeneration in these conditions may begin up to 15 years before the onset of clinical symptoms, opening avenues for pre‐clinical detection via sensitive tasks. Such a mission is particularly critical in HD, given that patients’ children have 50% chances of inheriting the disease. Against this background, we assessed whether deficits in the above‐mentioned domains emerge in subjects at risk to develop HD. We administered tasks tapping action semantics, object semantics, and two forms of syntactic processing to 18 patients with HD, 19 asymptomatic first‐degree relatives, and sociodemographically matched controls for each group. The patients evinced significant deficits in all tasks, but only those in the two target domains were independent of overall cognitive state. More crucially, relative to controls, the asymptomatic relatives were selectively impaired in action semantics and in the more complex syntactic task, with both patterns emerging irrespective of the subjects’ overall cognitive state. Our findings highlight the relevance of these dysfunctions as potential prodromal biomarkers of HD. Moreover, they offer theoretical insights into the differential contributions of frontostriatal hubs to both domains while paving the way for innovations in diagnostic procedures.     

Attachment styles and clinical correlates in people at ultra high risk for psychosis

Evidence suggests that attachment styles may influence subclinical psychosis phenotypes (schizotypy) and affective disorders and may play a part in the association between psychosis and childhood adversity. However, the role of attachment in the initial stages of psychosis remains poorly understood. Our main aim was to describe and compare attachment styles in 60 individuals at ultra high risk for psychosis (UHR) and a matched sample of 60 healthy volunteers (HV). The HV had lower anxious and avoidant attachment scores than the UHR individuals (p < .001). Sixty-nine percentage of the UHR group had more than one DSM-IV diagnosis, mainly affective and anxiety disorders. The UHR group experienced more trauma (p < .001) and more mood and anxiety symptoms (p < .001). Interestingly, in our UHR group, only schizotypy paranoia was correlated with insecure attachment. In the HV group, depression, anxiety, schizotypy paranoia, and social anxiety were correlated with insecure attachment. This difference and some discrepancies with previous studies involving UHR suggest that individuals at UHR may compose a heterogeneous group; some experience significant mood and/or anxiety symptoms that may not be explained by specific attachment styles. Nonetheless, measuring attachment in UHR individuals could help maximize therapeutic relationships to enhance recovery.     

Academic goals and learning strategies in secondary education Spanish students with social anxiety / Metas académicas y estrategias de aprendizaje en estudiantes españoles de Educación Secundaria Obligatoria con ansiedad social

The purpose of this study was to analyse the relationship between high social anxiety, academic goals and learning strategies in a sample of 2,022 (51.1% male) Spanish adolescents aged 12–16. The Social Phobia and Anxiety Inventory (SPAI), Achievement Goal Tendencies Questionnaire (AGTQ) and Learning and Studies Skills Strategies Inventory — High School Version (LASSI-HS) were used to assess the variables. The results showed no statistically significant differences in goal orientations between students with and without high social anxiety. However, students with high social anxiety used learning strategies significantly less. In addition, the logistic regression results indicated that high social anxiety acts as a significant predictor for setting social reinforcement goals and learning and study strategies.     

Reading the Lives of Others: Biography as Political Thought in Hannah Arendt and Simone de Beauvoir

In this essay, I focus on two biographical works by Hannah Arendt and Simone de Beauvoir that I read as political texts: Rahel Varnhagen: The Life of a Jewess (Arendt 1957 ) and “Must We Burn Sade?” (Beauvoir 2012 ). Reading Arendt's Varnhagen and Beauvoir's “Sade” side by side illuminates their shared preoccupation with lived experience and their common political premises: the antagonism between freedom and sovereignty, and the centrality of action and constructive relations with others. My argument is that these texts constitute an original style of political thinking, which I call politico‐biographical hermeneutics, or reading the life of others as exercises in political theory. Politico‐biographical hermeneutics, as I take it, is not a systematic methodology, but an approach to interpreting sociopolitical forces as they come to bear and are embodied and inscribed in the lived experiences, struggles, and works of representative or exemplary individuals. This approach identifies the political lessons of lived experience and supports one of the central claims of feminist philosophy, namely, that the personal and the political are not antithetical, but relational.     

Team Development: Definition,Measurement and Relationships with Team Effectiveness

This article describes the development and validation of a theory-based measure of team development. Drawing on 3 independent samples, including multisource and 2-wave data, we found support for the scale’s theoretical multidimensionality. Convergent and discriminant validity was established, and criterion-related validity was determined through the scale’s relation with 3 facets of team effectiveness: viability, extrarole performance, and reputation. We conclude that the 29-item measure is valid and reliable for the assessment of team development. Theoretically, we shed light on the dimensionality of team development and extend the available knowledge on its nomological network. Practical implications for enhancing team effectiveness via team development are discussed.     

The future is now: the impact of present fluency in judgments about the future

Recent research has emphasised the role of episodic memory in both remembering past events and in envisaging future events. On the other hand, it has been repeatedly shown that judgments about past events are affected by the fluency with which retrieval cues are processed. In this paper we investigate whether perceptual fluency also plays a role in judgments about future events. For this purpose we conducted four experiments. The first experiment replicated recent findings showing that stimuli that are processed fluently tend to be wrongly recognised as having been encountered in the past outside the laboratory walls [Brown, A. S., & Marsh, E. J. (2009). Creating illusions of past encounter through brief exposure. Psychological Science, 20, 534–538. doi:10.1111/j.1467-9280.2009.02337.x]. Two follow-up experiments using Brown and Marsh’s [(2009). Creating illusions of past encounter through brief exposure. Psychological Science, 20, 534–538. doi:10.1111/j.1467-9280.2009.02337] task tested the influence of perceptual fluency on future judgments. The fourth and last experiment was designed to rule out a potential confounding factor in the two previous experiments. Across experiments, we found that people rely on fluency when making judgments about events that are yet to come. These results suggest that fluency is an equally valid cue for past and future judgments.
