In the field of vocabulary acquisition, there have been many studies on the efficacy of word lists.

This study investigated which of the five types of word lists (synonyms, antonyms,…

Learning to read is a major obstacle for children who are deaf. The otherwise significant role of phonology is often limited as a result of hearing loss. However, semantic knowledge may facilitate reading comprehension. One important aspect of semantic knowledge concerns semantic categorization. In the present study, the quality of the semantic…

An eye tracking methodology was used to evaluate 3- and 4-year-old children's sensitivity to speaker affect when resolving referential ambiguity. Children were presented with pictures of three objects on a screen (including two referents of the same kind, e.g., an intact doll and a broken doll, and one distracter item), paired with a prerecorded…

The article presents 30-year bibliometrical results on trends in the scope, internationality, and impact of the "International Journal of Behavioral Development" ("IJBD") from its inception in 1978 to 2007.

A central question in creativity concerns how insightful ideas emerge. Anecdotal examples of insightful scientific and technical discoveries include Goodyear's discovery of the vulcanization of rubber, and Mendeleev's realization that there may be gaps as he tried to arrange the elements into the Periodic Table. Although most people would regard…

We examined differences among 158 children, 44 with selective mutism (SM; M = 8.2 years, SD = 3.4 years), 65 with mixed anxiety (MA; M = 8.9 years, SD = 3.2 years), and 49 community controls (M = 7.7 years, SD = 2.6 years) on primary caregiver, teacher, and child reports of behavioral and socio-emotional functioning.

"Highly iconic" structures in Sign Language enable a narrator to act, switch characters, describe objects, or report actions in four-dimensions. This group of linguistic structures has no real spoken-language equivalent. Topographical descriptions are also achieved in a sign-language specific manner via the use of signing-space and…

Purpose: The purposes of this study were (a) to determine whether highly experienced clinicians and researchers agreed with each other in judging the presence or absence of stuttering in the speech of children who stutter and (b) to determine how those binary stuttered/nonstuttered judgments related to categorizations of the same speech based on…

Perceptual grouping is a pre-attentive process which serves to group local elements into global wholes, based on shared properties. One effect of perceptual grouping is to distort the ability to estimate the distance between two elements. In this study, biases in distance estimates, caused by four types of perceptual grouping, were measured across…

Eighty-nine adolescent group sex offenders (mean age = 14.9, SD = 1.4) referred by the police to the Dutch child…
