Younger brains are noisier information processing systems; this means that information for younger individuals has to allow clearer differentiation between those aspects that are required for the processing task in hand (the "signal") and those that are not (the "noise"). We compared toddler-directed and adult-directed TV…

The study of development vacillates between a focus on change (i.e., studying how and why infants are so different from adults) and excitement about early competence and continuity (i.e., studying how capable infants are, and marveling at how similar they turn out to be to adults). The study of memory development has been no exception. This…

A known contributor to adults' superior memory performance compared to children is their differential reliance on an existing knowledge base. Compared to those of adults, children's semantic networks are less accessible and less established, a difference that is also thought to contribute to children's relative resistance to semantically related…

Do the emotional valence and arousal of events distort children's memories? Do valence and arousal modulate counterintuitive age increases in false memory? We investigated those questions in children, adolescents, and adults using the Cornell/Cortland Emotion Lists, a word list pool that induces false memories and in which valence and arousal can…

Children differ in how quickly they reach linguistic milestones. Boys typically produce their first multi-word sentences later than girls do. We ask here whether there are sex differences in children's gestures that precede, and presage, these sex differences in speech. To explore this question, we observed 22 girls and 18 boys every 4 months as…

The Critical Period Hypothesis aims to investigate the reason for significant difference between first language acquisition and second language acquisition. Over the past few decades, researchers carried out a series of studies to test the validity of the hypothesis. Although there were certain limitations in these studies, most of their results…

Reading-specific and general color-shape cognitive flexibility were assessed in 68 first and second graders to examine: 1) the development of graphophonological-semantic cognitive flexibility (the ability to process concurrently phonological and semantic aspects of print) in comparison to color-shape cognitive flexibility, 2) the contribution of…

The effects of associative strength and gist relations on rates of children's and adults' true and false memories were examined in three experiments. Children aged 5-11 and university-aged adults participated in a standard Deese/Roediger-McDermott false memory task using DRM and category lists in two experiments and in the third, children…

Recent research has indicated that conceptual development in a specific domain may not be independent of the way it is mapped linguistically. We explore this claim in the semantic domain of evidentiality by considering various sets of data from Turkish-speaking children between one and a half to six years. We present evidence for (1) the…

We describe the nature of the evidential system in Tibetan and consider the challenges that any evidential system presents to language acquisition. We present data from Tibetan-speaking children that shed light on their understanding of the syntactic and semantic properties of evidentials, and their competence in the point-of-view shift required…

Older adults sometimes show a recall advantage for emotionally positive, rather than neutral or negative, stimuli (S. T. Charles, M. Mather, & L. L. Carstensen, 2003). In contrast, younger adults respond "old" and "remember" more often to negative materials in recognition tests. For younger adults, both effects are due to…

The ability of school children (N = 233) to acquire new scientific vocabulary was examined. Children from two age groups (M = 4.8 and M = 6.5) were introduced to previously unknown words in an educational video. Word knowledge was assessed through accuracy and latency for production and comprehension over a 9-month period. A draw and write task…

The author investigated the importance of processing considerations within implicit memory in a developmental design. Second-graders (n = 87) and college students (n = 81) completed perceptual (word stem completion) and conceptual (category generation) implicit memory tests after studying target items either nonsemantically (read) or semantically…

Language disabled (LD) and average (N=40) six- and eight-year-olds were evaluated on the ability to detect multiple word meanings in ambiguous sentences with and without picture clues and to identify appropriate word meaning by sentence context. LD students did not show average growth in these abilities over the two-year age span. (Author/DB)

This article considers how children and young people conceptualize and construct different types of texts. The initial parts of narrative and expository texts written by grade-schoolers, adolescents, and adults were analyzed, on the assumption that the opening to a piece of discourse serves as a window on the text as a whole. Analysis was…
