The current work examined age differences in the classification of novel object images that vary in continuous dimensions of structural shape. The structural dimensions employed are two that share a privileged status in the visual analysis and representation of objects: the shape of discrete prominent parts and the attachment positions of those…

The purpose of this study was to further researchers' understanding of lexical acquisition in the beginning primary schoolchild by investigating word learning in small-group elementary science classes. Two experiments were conducted to examine the role of semantic scaffolding (e.g., use of synonymous terms) and physical scaffolding (e.g., pointing…

Older and younger adults' abilities to use context information rapidly during ambiguity resolution were investigated. In Experiments 1 and 2, younger and older adults heard ambiguous words (e.g., fires) in sentences where the preceding context supported either the less frequent or more frequent meaning of the word. Both age groups showed good…

The authors posit that women can rely on self-monitoring to overcome negative gender stereotypes in certain performance contexts. In a study of mixed-sex task groups, the authors found that female group members who were high self-monitors were considered more influential and more valuable contributors than women who were low self-monitors. Men…

Clahsen and Felser (CF) analyze the performance of monolingual children and adult second language (L2) learners in off-line and on-line tasks and compare their performance with that of adult monolinguals. They conclude that child first language (L1) processing is basically the same as adult L1 processing (the contiguity assumption), with…

Beginning in July 2002, the Health Sciences Library at the University of North Carolina at Chapel Hill underwent an 11 million dollar renovation. During three phases of the renovation, parts of the collection were inaccessible to patrons. In order to continue to make the library's collection available, library staff created a paging system.…

This paper reports on a design experiment in the domain of number sequences conducted in the course of the "WebLabs" project. We iteratively designed and tested a set of activities and tools in which 10-14 year old students used the "ToonTalk" programming environment to construct models of sequences and series, and then shared…

Recently, tasks have been advocated for their role in promoting participation in L2 interaction and the provision and use of feedback by language learners (Bygate, M., Skehan, P., Swain, M. (Eds.), 2001. "Researching Pedagogical Tasks: Second Language Learning, Teaching and Testing." Pearson Education, Harlow). The relationship between various…

Previous research on infant swimming has reported contradictory findings. Cross-sectional observations revealed a disorganized phase between about 3 and 12 months, which was attributed to "cortical inhibition" and implied slow learning (McGraw, 1939). However, training with a single infant during this period revealed rapid acquisition (McGraw,…

This study examined the influence of children's emotion situation knowledge (EK) on their autobiographical memory ability at both group and individual levels. Native Chinese, Chinese immigrant, and European American 3-year-old children participated (N = 189). During a home visit, children recounted 2 personal memories of recent, 1-time events with…

Anderson & Green (2001) have recently shown that using an adaptation of the go-no go task, participants can voluntarily inhibit the retrieval of specific memories. We present three experiments in which we try to determine the degree of automaticity involved, and the role of the previous prime-target relation on the development of this inhibitory…

This study investigated whether individual differences in learners' age of arrival (AOA) and length of residence (LOR) in a country where a second language (L2) is spoken determine the relationship between L2 perception and production. In the first experiment, 40 Korean learners of English and 10 native English speakers participated in vowel…

Translating numerals into number words is a tacit task requiring linguistic and mathematical knowledge. This project expanded on previous number production models by examining developmental differences in children's number naming errors. Ninety-six children from grades one, three, five, and seven translated a random set of numerals into number…

Previous research has shown that individual differences in working memory (WM) are highly predictive of a wide range of cognitive behaviours. Until recently, research has focused on monolingual, or undifferentiated, populations. The present research compares metacognitive awareness, as measured by self-ratings of reading, writing, speaking and…

We compared two procedures (video prompting versus video modeling) for teaching six adults with developmental disabilities to set a table and put away groceries. Video prompting involved 10 separate video clips, each showing one step of the task analysis. Video modeling involved a single video showing all 10 steps from beginning to end. After…
