Vygotsky measured his 'zone of proximal development' in years. To do this, he needed a scheme of age periods, and a set of tasks that could diagnose the next age period without defining it. In this paper, we compare the age periods in his late lectures with Halliday's categories of logico-semantic expansion as used by three adolescent…

Primary education is compulsory around the world. This means that around age 5 or 6, millions of children worldwide transition from home or preschool/kindergarten settings into primary school, with the success of this transition shaping school and life trajectories for years to come. Both developmental and environmental factors during early…

Wittgenstein scholars have tended to interpret the acquisition of certainties, and by extension, of a world-picture, as the achievement of a state in which these certainties are assimilated in a seemingly unconscious way as one masters language-games. However, it has not been stressed that the attainment of this state often involves facing a…

The article is an attempt to discover how useful the existing literature in field of designing children's playful learning products, is for people who wish to create quality toys and games. It sets out from the right of children to play, and the assertion that plays is crucial for the development of children, to the massive size of the global toy…

This research investigates the development of constraints in word learning. Previous experiments have shown that as infants gain more knowledge of native language structure, they become more selective about the forms that they accept as labels. However, the developmental pattern exhibited depends greatly on the way that infants are introduced to…

The public emphasis on 'lost learning' and hapless child victims fails to acknowledge children's drive to learn and misconceives the role of the teacher. Through direct conversations and close observations Emily Rowe, class teacher, and Jeni Smith, school governor, worked together to learn from year 5 and 6 children about their experiences of…

Stimulus over-selectivity is said to have occurred when only a limited subset of the total number of stimuli present during discrimination learning controls behavior, thus, restricting learning about the range, breadth, or all features of a stimulus. The current study investigated over-selectivity of 100 typically developing children, aged 3-7…

In this study, it was aimed to examine the opinions of preschool children towards their peers with disabilities and the characteristics that affect these views. This research is a qualitative study. In the research in which qualitative data analysis techniques are used, the basic data collection source is the semi-structured interview form. The…

Learning to walk allows infants to travel faster and farther and explore more of their environments. In turn, walking may have a cascading effect on infants' communication and subsequent responses from caregivers. We tested for an "inflection point"--a dramatic shift in the developmental progression--in infant communication and caregiver…

In the present study, a concurrent multiple baseline design across participants was used to evaluate the efficacy of pivotal response treatment (PRT) on the acquisition, maintenance, and generalization of the question-asking initiations by four children with autism spectrum disorder (ASD). The researchers also examined whether the implementation…

This 5-year longitudinal study investigated advanced theory-of-mind (AToM) development in 161 German 5- to 10-year-olds (89 females, 72 males). Core aspects of AToM developed nonlinearly, with children reaching a milestone at the age of 7 years, around when they attained the conceptual insight that mental states can be recursive. In late…

Infants come to know about the world and develop an understanding about themselves through multisenses. This qualitative case study aimed to explore how three infant head teachers engaged in and facilitated various multisensory play activities in their classrooms. Natural, in-class, non-participatory observations were conducted at a child care…

Existing studies have explored parental play beliefs in the developed coastal cities in mainland China, leaving parents in developing areas unstudied. This study aimed to understand how these understudied parents view and engage in their children's play at home, using Bronfenbrenner's process--person--context--time (PPCT) model. Eight families…

Although abuse and neglect in the early years of life have been reliably linked to poor mental health outcomes in childhood, only a few studies have examined whether the predictive significance of childhood abuse and neglect endures for symptoms of psychopathology into adulthood. Here we examined to what extent prospectively assessed child abuse…

The study examines phases in developing specification of grammatical marking of emergent clause-combining (CC) as indicative of children's growing ability to integrate two or more independent predications. To this end, both intra- and inter-clausal analyses were applied to all CC utterances produced by three Hebrew-acquiring children aged 2;0-3;0,…
