In this article, I briefly review theories about the development of theory of mind, and then examine evidence for minimalism, the idea that infants initially understand only behaviors. To this end, I consider the need for a wide variety of species to predict the behaviors of other animals and that human infants are not unique in this regard. I…

The aim of this study was to examine the developmental trajectories of comprehension of relational concepts among 557 participants with intellectual disability (ID) of undifferentiated etiology (M age = 12.20 years, SD = 3.18) and 557 typically developing (TD) participants (M age = 4.57 years, SD = 0.80). Logistic regression analyses, with…

This transnational comparative study between Costa Rica and the United States provides an in-depth understanding of the similarities and differences of the early literacy practices of educators in the Pre-Kindergarten to Kindergarten classroom settings. Drawing upon Costa Rica's curricular approach to Early Childhood Education, based upon the…

Abstract Few studies have examined how socioeconomic status (SES) affects two essential parts of human development, namely vocabulary and reading comprehension, in children facing severe poverty. The Roma population is the largest minority group in Europe, the majority of whom live in severe poverty. This study compared the development of 322 Roma…

Both early childhood maternal language input and the quality of classroom instruction in elementary school have been shown to be important environmental supports in predicting children's literacy skill development. However, no studies have simultaneously examined these two environmental supports in relation to children's early language skills and…

Children normally feel unable or less confident to express their ideas clearly, freely, and critically both orally and in writing when learning a language. Research has demonstrated that children's early exposure to Bloom's Taxonomy levels in stories has a "remarkable power" on them (Dickinson, et al. 2012) and helps develop their…

The present study followed a sample of first-grade (N = 316, M[subscript age] = 7.05 at first test) through fourth-grade students to evaluate dynamic developmental relations between vocabulary knowledge and reading comprehension. Using latent change score modeling, competing models were fit to the repeated measurements of vocabulary knowledge and…

The home environment, which includes the level of organization and stability in the home, plays a crucial role in the development of executive function and oral language skills. For children who live in a low-SES environment, executive function and oral language acquisition are inferior compared to that of students living at other economic levels.…

There is accumulating correlational evidence that the effect of specific types of reading instruction depends on children's initial language and literacy skills, called child characteristics x instruction (CxI) interactions. There is, however, no experimental evidence beyond first grade. This randomized control study examined whether CxI…

This article highlights the importance of the information obtained from the family in the implementation of the augmentative and alternative communication (AAC) system. The objective was to investigate the communicative abilities of children with severe communication deficit through their parents' reports within the family routine. Eleven parents…

The Workshop on the Role of Language in School Learning: Implications for Closing the Achievement Gap was held to explore three questions: What is known about the conditions that affect language development? What are the effects of early language development on school achievement? What instructional approaches help students meet school demands for…

Forty toddlers aged 20 to 24 months were presented with 32 pairs of images with the auditory stimulus Look followed by the name of the target image (e.g. "Look...tree") in an intermodal preferential looking (IPL) paradigm. The same series of 16 items was presented first with one image as target and then with the other member of the pair as target.…

Efforts to improve the educational achievement of children, especially those from disadvantaged backgrounds, are at the heart of current government policies in the United Kingdom. The Peers Early Education Partnership (PEEP) is an intervention that, since 1995, has worked directly with parents and caregivers of children from infancy to 5 years of…

Studied the average development of word recognition, reading comprehension, vocabulary, and spelling of poor and better readers during the elementary school period and studied whether differences between these readers increased over time. Results for 3 cohorts of about 900 children each contradict the existence of a Matthew effect for word…

We assessed 19-month-olds' appreciation of the conventional nature of object labels versus desires. Infants played a finding game with an experimenter who stated her intention to find the referent of a novel word (word group), to find an object she wanted (desire group), or simply to look in a box (control group). A 2nd experimenter then…
