School-based screening instruments have traditionally focused on assessing within-child factors, such as a student's academic, social, emotional, behavioral, or physical development. This emphasis in school-based screening may be a missed opportunity to assess and ameliorate contextual factors (i.e., social determinants of health) influencing…

Purpose: As a class, fricatives are more "resistant" to consonant-vowel coarticulation than other English sounds. This study investigates the relative coarticulatory resistance of /[voiceless dental fricative], s, [voiceless palato-alveolar fricative]/ in child and adult speech to better understand the acquisition of individuated speech…

Purpose: Liquids are among the last sounds to be acquired by English-speaking children. The current study considers their acquisition from an articulatory timing perspective by investigating anticipatory posturing for /l/ versus /[voiced alveolar approximant]/ in child and adult speech. Method: In Experiment 1, twelve 5-year-old, twelve…

Individuals' implicit theories of intelligence exist on a spectrum, from believing intelligence is fixed and unchangeable, to believing it is malleable and can be improved with effort. A belief in malleable intelligence leads to adaptive responses to challenge and higher achievement. However, surprisingly little is known about the development of…

This study investigated whether the types and amount of playful activity and thought exhibited from early childhood to adulthood are related to aspects of moral development, such as empathy, behavior, and reasoning. It explored whether the assertions of theorists such as Piaget, Vygotsky, and Erikson regarding the facilitative effect of games with…

A crucial skill in scientific and everyday reasoning is the ability to interpret data. The present study examined how data features influence data interpretation. In Experiment 1, one hundred and thirty-three 9-year-olds, 12-year-olds, and college students (mean age = 20 years) were shown a series of data sets that varied in the number of…

The numerical distance effect (inverse relationship between numerical distance and reaction time in relative number comparison tasks) has frequently been used to characterize the mental representation of number. The size of the distance effect decreases over developmental time. However, it is unclear whether this reduction simply reflects…

The authors proposed that birth order affects psychosocial outcomes through differential investment from parent to child and differences in the degree of identification from child to parent. The authors conducted this study to test these 2 models. Despite the use of statistical and methodological procedures to increase sensitivity and reduce…

This book contains a compilation of papers presented at the International Psychological Applications Conference and Trends (InPACT) 2018, organized by the World Institute for Advanced Research and Science (W.I.A.R.S.). Modern psychology offers a large range of scientific fields where it can be applied. The goal of understanding individuals and…

The Deese/Roediger-McDermott (DRM) paradigm was used to investigate developmental trends in accurate and false memory production. In Experiment 1, DRM lists adjusted to be more consistent with children's vocabulary were used with 2nd graders, 8th graders, and college students. Accurate and false recall and recognition increased with age, but…

The purpose of this article is to describe and analyse play through a contemporary historical perspective, based upon pre-school teachers', students majoring in education, and teacher education students' descriptions of memories from their childhood regarding play and toys. The overall method is retrospective. The data consists of 111 interviews…

Investigated different age groups' knowledge of developmental norms of children. Collected data from 280 midwestern university students through a questionnaire. Results showed that knowledge of normal development was both over- and underestimated regardless of age of student or year in school. (BH)

Studies the earliest childhood memories of 82 deaf and hearing college students. Results indicate no significant difference in the age of the earliest recollections among the students. The average age of the first memory was between 3 and 4 years. (RJC)

Six experiments involving 192 infants and 1 experiment with 16 college students examined sensitivity to acoustic correlates of phrasal units in English. A basic finding is that nine-month-old infants are sensitive to acoustic markers that correspond to major phrasal units, a sensitivity that develops after six months. (SLD)
