This research investigated how children build up the language-specific system of the color lexicon, examining factors that play important roles for the construction of an adult-like color lexicon. We had 3-, 4-, and 5-year-old Japanese-speaking children and adults (n = 20, 18, 19, and 19, respectively) produce names for 93 color swatches. The…

Purpose: Normal-hearing (NH) children acquire plural morphemes at different rates, with the segmental allomorphs /-s, -z/ (e.g., cat-s) being acquired before the syllabic allomorph /-[schwa]z/ (e.g., bus-es). Children with hearing loss (HL) have been reported to show delays in the production of plural morphology, raising the possibility that this…

Children and adults appreciate that physical action is typically the conduit between individuals' desires and the fulfillment of those desires. However, certain forms of petitionary thought -- e.g., wishing and praying -- are believed by many people to influence the external world and fulfill desires without direct physical action. We examine…

Although it has long been known that time is a cue to causation, recent work with adults has demonstrated that causality can also influence the experience of time. In "causal reordering" (Bechlivanidis & Lagnado, 2013, 2016) adults tend to report the causally consistent order of events rather than the correct temporal order. However,…

The purpose of this study is to conduct a non-systematic meth-analysis of a literature review by way of reviewing research that was found in any databases under the terms "urban health services" in order to document the major factors influencing urban health among minorities; and if there are any policies that promote health and prevent…

Recent literature shows that younger cohorts have lower levels of literacy ceteris paribus in Canada, the United States, Norway and other developed countries. Very few explanations are provided to justify the existence of this negative cohort effect. Yet this decline has serious implications for the economy, education system and society. In this…

Through providing an external support to speech, gesture observation may benefit a student's learning in a variety of areas, including narrative comprehension. Across two studies, we investigated factors that could moderate when gestures are most beneficial to narrative comprehension, including gesture type, task difficulty, and age, in order to…

Purpose: Early language and speech acquisition can be delayed in twin children, a twinning effect that diminishes between 4 and 6 years of age in a population-based sample. The purposes of this study were to examine how twinning effects influence the identification of children with language impairments at 4 and 6 years of age, comparing children…

The aim of this study was to examine trends in cannabis use among Spanish students from 2006 to 2018 by sex, age, and sex and age combined. Data showed a global decrease both in a lifetime and frequent cannabis use between 2006 and 2018 but four-year comparisons revealed more variability within the specific sex-age groups. No change was found in…

Relative age effects occur when older and younger students are peers in the same classroom. Previous research in this field has shown that older children have higher academic achievement compared to the youngest children in the same grade. This study examined the effects of separating kindergarten students into classes based solely on age. The…

Purpose: Given declining tuition funds and government grants, Kenyan universities need to develop strategies, including increased research grants and collaborations, to diversify their income sources. Well-managed doctoral students can boost a university's teaching and research outputs. However, numbers of students enrolled in doctoral programmes…

The increasing global mobility of students has heightened the need for deeper insights into the psychological and sociocultural adaptation processes in host environments. This study examines the adaptation experiences of 447 international students in Hungary, focusing on the interplay between psychological and sociocultural dimensions of…

This study offers a comprehensive investigation of 14-15-year-old students' comprehension of non-Euclidean geometries, with a specific focus on the assessment of their understanding through a 15-itemed test. The primary objective of this research is to assess the current state of students' knowledge and proficiency in non-Euclidean geometries and…

In Early Childhood Education and Care (ECEC) programs, the quality of teacher-child interactions is regarded to be important for children's vocabulary development. However, prior studies on the relationships between teacher and child, as measured by the Classroom Assessment Scoring System (CLASS), and children's vocabulary skills are inconsistent.…

The association between the quality of teacher-student relationships and children's psychological adjustment has been mainly studied in Western countries; however, this research topic is gaining more interest in Eastern countries. Based on attachment theory and empirical evidence, this cross-sectional study examined the relationship between…
