Effects of race of examiner and type of reinforcement on the intelligence test performance of lower-class black children

This study examined the effects of race of examiner and type of reinforcement upon the WISC-R performance of lower-class black children. A total of 120 black males were selected and assigned to either a white or black examiner to form two groups. Within each group, children were given no reinforcement, tangible reinforcement, traditional social reinforcement, or culturally relevant social reinforcement after each correct response. Children given tangible rewards, regardless of race of examiner, obtained significantly higher scores than did children given no reinforcement or children given traditional social reinforcement. Also, children given culturally relevant social reinforcement by a black examiner obtained significantly higher scores than did children given culturally relevant reinforcement by the white examiner.     

Intelligibility is equity: Can international students read undergraduate admissions materials?

Fewer international students have applied to and enrolled in US institutions, as 40 per cent of US institutions reported a drop in international applications since 2016. Subsequently, US institutions must ensure that their international admissions materials are as equitable and transparent as possible. Expanding previous work, this study examines the readability and translation of international undergraduate admissions materials of 335 four‐year public and non‐profit private US institutions. Results reveal these materials are written near a 14th‐grade reading comprehension level, only 1 per cent of institutions provide web‐embedded translation tools on their websites and 91 per cent of institutions provide English‐only content. Implications for practitioners, policymakers and future research are addressed.     

Shifting Practices,Shifting Selves: Negotiations of Local and Global Cultures Among Adolescents in Northern Thailand

Around the world, adolescents increasingly grow up as members of local and global cultures. Little is known, however, about how precisely adolescents in rapidly globalizing societies blend local and global cultures. Interviews with 40 (16- to 19-year old) Thai adolescents, evenly divided between rural and urban communities, were analyzed alongside participant observation data for the interplay between local and global linguistic and dietary practices. Results revealed that urban adolescents inhabited differentiated selves, alternating between local and global practices based on interactional partner. The activation of each assisted them in navigating—and in some cases, reshaping—hierarchies encountered in everyday relationships. Findings contribute to the developmental science of globalization and point to the utility of interrogating cultural practices as sites of self-negotiation in rapidly changing cultural contexts.     

Self-Determination to Increase Oral Reading Fluency Performance: Pilot and Replication Single-Case Design Studies

We report findings from multiple baseline design studies examining the effects of a program (“Data Mountain”) to improve the oral reading fluency (ORF) performance of 12 third-grade students with significant reading difficulties. The Data Mountain program guided students through self-monitoring, goal setting, and motivation training related to their reading performance. In the pilot study, these components were introduced across two experimental phases (self-monitoring and goal setting, followed by motivation training) to observe potential additive effects. In the replication study, the full Data Mountain program was introduced in one experimental phase. Between-case standardized mean difference effect sizes yielded moderate effects across studies (ES = 0.53, 0.63). Visual analyses of data revealed that students demonstrated increased levels of words read correctly per minute (wpm). In the pilot study, students’ fluency increased to an average of 22 wpm in the self-monitoring and goal-setting phase, and to a further 9 wpm in the motivation training phase. In the replication study, students increased an average of 18 wpm with the Data Mountain program. These results provide evidence to suggest that self-determination and motivation training have the potential to support the ORF performance of students with significant reading difficulties in the elementary grades.     

Interleukin-6 and Delayed Onset Muscle Soreness Do Not Vary During the Menstrual Cycle

The purpose of this study was to determine if a difference in interleukin-6 (IL-6) and delayed onset muscles soreness (DOMS) exists in two different phases of the menstrual cycle. Nine runners performed one 75-min high-intensity interval running session during the early follicular (EF) phase and once during the midluteal (ML) phase of the menstrual cycle. Estrogen and progesterone levels were significantly reduced in the EF phase when compared to the ML phase. IL-6 levels increased from pre- to postexercise in the EF and ML phases (p < .001). There was no relationship between the IL-6 level and DOMS. The results suggest that menstruating female runners need not vary training throughout the month to reduce DOMS.     

The componential model of reading: predicting first grade reading performance of culturally diverse students from ecological, psychological, and cognitive factors assessed at kindergarten entry

This study, framed by the component model of reading (CMR), examined the relative importance of kindergarten-entry predictors of first grade reading performance. Specifically, elements within the ecological domain included dialect, maternal education, amount of preschool, and home literacy; elements within the psychological domain included teacher-reported academic competence, social skills, and behavior; and elements within the cognitive domain included initial vocabulary, phonological, and morpho-syntactic skills, and alphabetic and word recognition skills. Data were obtained for 224 culturally diverse kindergarteners (58% Black, 34% White, and 8% Hispanic or other; 58% received free or reduced-price lunch) from a larger study conducted in seven predominantly high poverty schools (n = 20 classrooms) in a midsized city school district in northern Florida. Results from a hierarchical multiple regression (with variables in the ecological domain entered first, followed by the psychological and cognitive domains) revealed a model that explained roughly 56% of the variance in first grade reading achievement, using fall-of-kindergarten predictors. Letter-word reading and morpho-syntactic skill were the strongest significant predictors. The findings largely support the CMR model as a means to understand individual differences in reading acquisition and, in turn, to support data-based instructional decisions for a wider range of children.     

What does it look like and what can it do? Category structure influences how infants categorize

Despite a large body of research demonstrating the kinds of categories to which infants respond, few studies have directly assessed how infants' categorization unfolds over time. Four experiments used a visual familiarization task to evaluate 10-month-old infants' (N = 98) learning of exemplars characterized by commonalities in appearance or function. When learning exemplars with a common function, infants initially responded to the common feature, apparently forming a category, and only learned the individual features with more extensive familiarization. When learning exemplars with a common appearance, infants initially learned the individual features and apparently only formed a category with more extensive familiarization. The results are discussed in terms of models of category learning.
