Jigsaw puzzles are ubiquitous developmental toys in Western societies, used here to examine the development of metarepresentation. For jigsaw puzzles this entails understanding that individual pieces, when assembled, produce a picture. In Experiment 1, 3- to 5-year-olds (N = 117) completed jigsaw puzzles that were normal, had no picture, or…

When problem behavior is controlled by a synthesized reinforcement contingency, a simple omnibus mand that yields access to all reinforcers simultaneously has been shown to effectively replace problem behavior. The question arises as to whether teaching an omnibus mand will preclude the acquisition of specifying mands for each of the combined…

Purpose: This study determined the time course of the emergence of prevocalic stop consonants in young children with cleft palate following surgical repair. Method: A total of 120 children in four cohorts from three institutions were followed from 12 to 24 months of age: (a) 24 with repaired cleft lip and palate (CLP), (b) 36 with repaired cleft…

This multistudy article examines whether children's susceptibility to their socialization experiences varies as a function of their dove temperament dispositions, an evolutionarily informed pattern of traits marked by a low threshold of environmental stimulation and greater behavioral flexibility across environmental contexts. Participants in…

This article feeds on new materialisms, especially the work of Barad, while re-turning and exploring child/LEGO/pedagogue/(re)searcher intra-actions in kindergarten and drawing attention to both human and non-human organisms as agentic forces that produce diffractions, affects and effects when they clash. The article places a special focus on one…

This study examines whether the Internet of Toys (IoToys) (de)limits children's make-believe play and whether the functionality and manipulatives offered by the IoToys serve as motivational pleasure (tactile, virtual and visual) for children to engage in make-believe play. Combining Piagetian and Vygotskian ideas of play as a unity of cognition…

The interplay between sense of entitlement and hope might have a unique contribution to mothers of children with developmental disabilities (DD) life satisfaction. Seventy-three mothers of children with DD and 47 mothers of children without DD participated in the study. Mothers of children with DD (vs. without DD) experienced low levels of life…

Purpose: This study examined the influences of bilingualism and developmental language disorder (DLD) on nonverbal processing speed. DLD is associated with slower processing speed, but the extent to which slowing extends to bilingual populations is not established. The possible presence of bilingual cognitive effects could also lead to faster…

Experimental studies examining child 'witnesses' under cross-examination typically rely on researchers questioning children using a 'barrister's script'. In the current research, experienced barristers used a defence statement from a mock perpetrator (who committed a theft 11 months earlier) to challenge typically developing children's evidence…

Ted Hughes is one of the most important poets in English literature of the last century and his huge volume of work (including his poetry, prose, plays, translations, letters and critical essays) has received a great deal of critical attention. Hughes was, of course, much more than just a writer. Throughout his life he was deeply engaged with…

Repetition compulsion is a psychodynamic concept that explains an attempt to master trauma. This case study attempts to understand the possible meanings of symbol repetition that occurred in the art therapy process of a twelve-year-old boy with acute methylmalonic acidemia. Over 29 sessions of art therapy, the client demonstrated repetition…

Purpose: This study aimed to gain more insight into the primary auditory abilities of children with significant residual hearing in order to improve decision making when choosing between bimodal fitting or sequential bilateral cochlear implantation. Method: Sound localization abilities, spatial release of masking, and fundamental frequency…

Memory for the temporal order of past events is a critical capacity; however, relatively little is known about its development and the processes that support it in early to middle childhood. The aim of this study was to examine children's memory for the temporal order of real-world events. Four-five-year-old (n = 36), 6-7-year-old (n = 45) and…

This study focuses on the multimodal communication of children with autism spectrum disorders (ASD) compared to typically developing (TD) children. Eleven children with ASD (aged from 28 to 79 months) and 11 TD children (from 12 to 30 months) were matched by their productive vocabulary. We observed their communicative production in a…

How might a 4-year-old pupil come to conceive a line, created by himself with a continuous gesture, as constituted by a series of points? In this paper, we theoretically introduce and discuss a design study of the educational path in which this possibility emerged. The path aimed at leading pupils to "experience," in the sense of the…
