Infants Segment Continuous Events Using Transitional Probabilities

Throughout their 1st year, infants adeptly detect statistical structure in their environment. However, little is known about whether statistical learning is a primary mechanism for event segmentation. This study directly tests whether statistical learning alone is sufficient to segment continuous events. Twenty‐eight 7‐ to 9‐month‐old infants viewed a sequence of continuous actions performed by a novel agent in which there were no transitional movements that could have constrained the possible upcoming actions. At test, infants distinguished statistically intact units from less predictable ones. The ability to segment events using statistical structure may help infants discover other cues to event boundaries, such as intentions, and carve up the world of continuous motion in meaningful ways.     

The Structure of Preschoolers’ Emotion Knowledge: Model Equivalence and Validity Using a Structural Equation Modeling Approach

Research Findings: A theory-based 2-factor structure of preschoolers’ emotion knowledge (i.e., recognition of emotional expression and understanding of emotion-eliciting situations) was tested using confirmatory factor analysis. Compared to 1- and 3-factor models, the 2-factor model showed a better fit to the data. The model was found to be equivalent for gender, race, age, and socioeconomic risk. Theory and the high correlation between the 2 latent factors suggested a hierarchical nature of development, in which a higher level of emotion knowledge is built upon a lower level. In our validity model, we found significant paths from the recognition to the situation factor and from the situation factor to teachers’ reports of preschoolers’ learning behaviors and social competence. Results provide further evidence of the significant role emotion plays in preschoolers’ school readiness. Practice or Policy: Early childhood educators can benefit from knowing that recognition of expressions and understanding of emotion-eliciting situations are appropriately teachable in this age range and can focus such teaching upon negative emotions and those that may vary across individuals. Furthermore, relations between these aspects of emotion knowledge and school readiness add to accumulating evidence that early childhood programming focusing upon emotion knowledge has multiple benefits.     

Exploring the Social Integration of Sexual Minority Youth Across High School Contexts

Mental health disparities between sexual minority and other youth have been theorized to result in part from the effects of the stigmatization on social integration. Stochastic actor‐based modeling was applied to complete network data from two high schools in the National Longitudinal Study of Adolescent Health (M_age = 15 years, N = 2,533). Same‐sex attracted youth were socially marginalized in a smaller predominantly White school but not in a larger, more racially diverse school. For both schools, homophily was a critical network feature, and could represent social support for and social segregation of such youth. These findings emphasize the school context in studying the social lives of sexual minority youth and suggest that youth may be better off socially in larger and more diverse schools.     

Text retrieval with more realistic concept matching and reinforcement learning

This paper reports our experimental investigation into the use of more realistic concepts as opposed to simple keywords for document retrieval, and reinforcement learning for improving document representations to help the retrieval of useful documents for relevant queries. The framework used for achieving this was based on the theory of Formal Concept Analysis (FCA) and Lattice Theory. Features or concepts of each document (and query), formulated according to FCA, are represented in a separate concept lattice and are weighted separately with respect to the individual documents they present. The document retrieval process is viewed as a continuous conversation between queries and documents, during which documents are allowed to learn a set of significant concepts to help their retrieval. The learning strategy used was based on relevance feedback information that makes the similarity of relevant documents stronger and non-relevant documents weaker. Test results obtained on the Cranfield collection show a significant increase in average precisions as the system learns from experience.     

Social-Emotional Competence as Support for School Readiness: What Is It and How Do We Assess It?

The overall issue of assessment during early childhood, and its relation to school readiness and other decisions, is currently widely debated. Expanding early childhood education and child care enrollments, better scientific knowledge about early childhood development, and decisions about public spending, necessitate careful consideration of which assessment tools to use, as well as why and when to use them. More specifically, the disconnection between the importance of social and emotional domains of development, and their status within educational programming and assessment, has long been lamented. The last several years have, however, witnessed a blossoming of attention to these areas during early childhood, as crucial for both concurrent and later well-being and mental health, as well as learning and academic success. Teachers view children's “readiness to learn” and “teachability” as marked by positive emotional expressiveness, enthusiasm, and ability to regulate emotions and behaviors. Based on these assertions, I suggest a battery of preschool social-emotional outcome measures, tapping several constructs central to emotional and social competence theory, specifically emotional expression, emotion regulation, emotion knowledge, social problem solving, and positive and negative social behavior.     

Victimization Disparities Between Heterosexual and Sexual Minority Youth From Ages 9 to 15

Mental health disparities between heterosexual and sexual minority youth are partly explained by the higher rates of victimization experienced by sexual minority youth. The onset and progression of these victimization disparities, however, are poorly understood. Using multirater longitudinal data, trajectories of victimization starting at age 9 were compared among youth who did and did not report same-sex attraction at age 15 (N = 310). Self and teacher, but not primary caregivers, reported victimization was significantly higher among sexual minority youth starting at age 9, but did not vary across time. The findings underscore the importance of understanding homophobic experiences of sexual minority youth during late childhood and early adolescence in order to inform prevention programs.     

Social-Emotional Learning Profiles of Preschoolers' Early School Success: A Person-Centered Approach

Examined how aspects of social-emotional learning (SEL)-specifically, emotion knowledge, emotional and social behaviors, social problem-solving, and self-regulation-clustered to typify groups of children who differ in terms of their motivation to learn, participation in the classroom, and other indices of early school adjustment and academic success. 275 four-year-old children from private day schools and Head Start were directly assessed and observed in these areas, and preschool and kindergarten teachers provided information on social and academic aspects of their school success. Three groups of children were identified: SEL Risk, SEL Competent-Social/Expressive, and SEL Competent-Restrained. Group members differed on demographic dimensions of gender and center type, and groups differed in meaningful ways on school success indices, pointing to needed prevention/intervention programming. In particular, the SEL Risk group could benefit from emotion-focused programming, and the long-term developmental trajectory of the SEL Competent-Restrained group requires study.     

Opportunities and Efficiencies in Building a New Service Desk Model

In July 2015, the Health Sciences and Human Services Library (HS/HSL) at the University of Maryland, Baltimore (UMB), merged its reference and circulation services, creating the Information Services Department and Information Services Desk. Designing the Information Services Desk with a team approach allowed for the re-examination of the HS/HSL’s service model from the ground up. With the creation of a single service point, the HS/HSL was able to create efficiencies, improve the user experience by eliminating handoffs, create a collaborative team environment, and engage information services staff in a variety of new projects.     

Cultivating critical game makers in digital game-based learning: learning from the arts

Digital games have the potential of being a transformative tool for applying constructionist principles to learning within formal and informal learning settings. Unfortunately, most recent attention has focused on instructionist games. Connected gaming provides a tantalizing alternative approach by calling for the development of games that are both instructive and modifiable by learners. If game design is to be used as a pedagogical tool in this manner, emphasis should be placed on the concurrent development of critical makers. In this paper, we advance the notion of connected gaming through positing a conception of a critical maker. To accomplish this, we look to the arts as a domain where pedagogical approaches are in place from which the game-based learning community can draw insights from, along with an overview of the potential challenges and opportunities that may accompany any attempt to develop critical makers.
