Socioeconomic attainment gaps in mathematical ability are evident before children begin school, and widen over time. Little is known about why early attainment gaps emerge. Two cross-sectional correlational studies were conducted in 2018-2019 with socioeconomically diverse preschoolers, to explore four factors that might explain why attainment…

Verbal memory is a fundamental prerequisite for language learning. This study investigated 7-month-olds' (N = 62) ability to remember the identity and order of elements in a multisyllabic word. The results indicate that infants detect changes in the order of edge syllables, or the identity of the middle syllables, but fail to encode the order…

This study investigated whether the effect of exposure to code-switching on bilingual children's language performance varied depending on verbal working memory (WM). A large sample of school-aged Spanish-English bilingual children (N = 174, Mage = 7.78) was recruited, and children were administered language measures in English and Spanish. The…

Through five waves of data collection, this longitudinal study investigated the development of spatial skills in 304 elementary school children (M[subscript age] = 7.64 years) as they progressed from the second to fourth grade. The study focused on whether multiple latent classes with different developmental profiles best explain development.…

This study examined the relation of 3-year core information-processing abilities to lexical growth and development. The core abilities covered four domains--memory, representational competence (cross-modal transfer), processing speed, and attention. Lexical proficiency was assessed at 3 and 13 years with the Peabody Picture Vocabulary Test (PPVT)…

The present study explored the environmental and genetic etiologies of the longitudinal relations between prereading skills and reading and spelling. Twin pairs (n = 489) were assessed before kindergarten (M = 4.9 years), post-first grade (M = 7.4 years), and post-fourth grade (M = 10.4 years). Genetic influences on five prereading skills (print…

This study investigated the relation between theory of mind (ToM) and metamemory knowledge using a training methodology. Sixty-two 4- to 5-year-old children were recruited and randomly assigned to one of two training conditions: A first-order false belief (ToM) and a control condition. Intervention and control groups were equivalent at pretest for…

The link between emotion regulation and academic achievement is well documented. Less is known about specific emotion regulation strategies that promote learning. Six- to 13-year-olds ("N" = 126) viewed a sad film and were instructed to reappraise the importance, reappraise the outcome, or ruminate about the sad events; another group…

The authors examined 284 maltreated and nonmaltreated children's (6- to 12-year-olds) ability to inhibit true and false memories for neutral and emotional information using the Deese/Roediger-McDermott (DRM) paradigm. Children studied either emotional or neutral DRM lists in a control condition or were given directed-remembering or…

This study explored the cognitive and behavioral profiles of children with working memory impairments. In an initial screening of 3,189 five- to eleven-year-olds, 308 were identified as having very low working memory scores. Cognitive skills (IQ, vocabulary, reading, and math), classroom behavior, and self-esteem were assessed. The majority of the…

This longitudinal study modeled growth rates, from ages 4.5 to 11, in English and Spanish oral language and word reading skills among 173 Spanish-speaking children from low-income households. Individual growth modeling was employed using scores from standardized measures of word reading, expressive vocabulary, and verbal short-term language…

This study explored the structure of verbal and visuospatial short-term and working memory in children between ages 4 and 11 years. Multiple tasks measuring 4 different memory components were used to capture the cognitive processes underlying working memory. Confirmatory factor analyses indicated that the processing component of working memory…

Investigated the relationship of two memory components involved in the retrieval of information from long-term memory--one process-oriented and one structure-oriented-- to variability associated with age and ability differences. Striking developmental differences obtained for retrieval efficiency were highly related to scores on tests of ability,…
