This paper estimates the acute effect of community-level homicides on early childhood language development and explores the moderating role of maternal efficacy and satisfaction in Chile. It uses data from the 2017 wave of the Early Childhood Longitudinal Survey of Chilean Children (N = 1194, M[subscript age]: 52.8 months, 52% girls). Children in…

Visually situated spoken words activate phonological, visual, and semantic representations guiding overt attention during visual exploration. We compared the activation of these representations in children with and without developmental language disorder (DLD) across four eye-tracking experiments, with a particular focus on visual (shape)…

Despite the important role assigned to analogical reasoning (AR) in cognition and language, the relationship between this ability and language skills in the emergent literacy period has not been sufficiently studied, especially in Spanish speakers. To explore this link, we examined two modalities of AR (verbal and non-verbal) as predictors of…

Introduction: Existing studies of the variables that can impact reading comprehension at intermediate levels of Primary Education are not entirely conclusive. The present study analyzes the contribution to reading comprehension made by domain-general skills, such as fluid intelligence (Gf) and working memory (WM), and domain-specific skills, such…

There is little evidence regarding the benefits of early center-based care attendance (before three years old) for child development and most studies have focused on developed countries. Addressing this gap, this study examines the relationship between center-based care attendance during toddler years and children's cognitive outcomes. Research…

The development of novel educational assessment models founded on item response theory (IRT), as well as software tools designed to implement these models, has contributed to the surge in computerized adaptive tests (CATs). The distinguishing characteristic of CATs is that the sequence of items on a test progressively adapts to the performance…

The purpose of the study was to reveal the cognitive characteristics of talented children who come from economically vulnerable contexts in Chile. Raven's Standard Progressive Matrices (SPM) was administered to a sample of 5,160 students who took part in the process of identification of gifted students from the program PENTA UC in Chile between…

Sentence repetition and non-word repetition tests are widely used measures of language processing which are sensitive to language ability. Surprisingly little previous work has investigated whether children's socio-economic status (SES) affects their sentence and non-word repetition accuracy. This study investigates sentence and non-word…

This study is about persistence and perceived difficulties of gifted students in college explored through sociodemographic and academic characteristics. Two hundred and nine nongifted and 45 gifted participated in the study. A persistence scale along with sociodemographic variables were used to compare both groups. The groups shared many…

The hypothesis that independently of sex, brain volume (BV) and head circumference (HC) are positively and significantly associated with intellectual quotient (IQ) was examined in a sample of 96 high school graduates of high [Wechsler Intelligence Scale for Adults--Revised (WAIS-R) is greater than 120] and low IQ (WAIS-R is less than 100) (1:1),…
