This research revealed both similarities and striking differences in early language proficiency among infants from a broad range of advantaged and disadvantaged families. English-learning infants ("n" = 48) were followed longitudinally from 18 to 24 months, using real-time measures of spoken language processing. The first goal was to…

General education teachers currently have children in their classrooms who are on the autism spectrum. These teachers have had little to no training in either their teacher preparation nor-school based professional development programs in teaching children on the spectrum. The purpose of this paper is to explore teaching strategies that are…

Young children frequently tell visual stories, drawing pictures to record and share their thoughts, feelings and understanding. How and what young children describe through art, especially when written language is not an option, is the focus of this interpretive analysis. A series of pictures by John, a 6-year-old boy, were drawn across the…

Cognitive strategies are important tools for children with math difficulties (MD) in learning to solve word problems. The effectiveness of strategy training, however, depends on working memory capacity (WMC). Thus, children with MD but with relatively higher WMC are more likely to benefit from strategy training, whereas children with lower WMC may…

Almost all locomotor animals are sensitive to optical expansion (visual looming) and for most animals this sensitivity is evident very early in their development. In humans there is evidence that responses to looming stimuli begin in the first 6 weeks of life, but here we demonstrate that as children become independent their perceptual acuity…

A course in system dynamics has been included in the first year of our university's six-year medical curriculum. System Dynamics is a discipline that facilitates the modelling, simulation and analysis of a wide range of problems in terms of two fundamental concepts viz. rates and levels. Many topics encountered in the medical school curriculum,…

This study examined whether 12-month-olds will accept words that differ phonologically and phonetically from their native language as object labels in an associative learning task. Sixty infants were presented with sets of English word-object (N = 30), Japanese word-object (N = 15), or Czech word-object (N = 15) pairings until they habituated.…

In September 1951, Radio Corporation of America chairman David Sarnoff celebrated his 45th year in the electronics industry by publicly challenging his research staff to develop three new technologies in time for his golden anniversary dinner 5 years later. This article considers the fate of one of these items, the "Magnalux" light amplifier, to…

Picture books can be used to teach children to infer, hypothesise, question, identify, explain and compare. By making the "invisible visible" preservice teachers in Canada explored ways to enhance the development of critical science and literacy skills through the creation of picture books in collaboration with students in Grades 5 and…

In this paper, different schools of thought are discussed and compared to encourage lively classroom discussion and interest in mathematics for high achieving Form 12 students and first (or higher) year university students enrolled in a mathematics degree program. In particular the work and views of two mathematicians, Kurt Godel (1931) and Ian…

We investigated the processing of threat-related, positive, and neutral words in parafoveal and in foveal vision as a function of individual differences in trait anxiety. In a lexical-decision task, word primes were presented for 150 ms either parafoveally (2.2[degrees] away from fixation; Experiment 1) or foveally (at fixation; Experiment 3)…

We show that in the grounded conducting sphere image problem, all the necessary information about the image charge can be found from a mirror equation and a magnification formula. Then, we propose a method to solve the image problem for an extended charge distribution near a grounded conducting sphere. (Contains 4 figures.)

Everyday experience suggests that drivers are less susceptible to motion sickness than passengers. In the context of inertial motion (i.e., physical displacement), this effect has been confirmed in laboratory research using whole body motion devices. We asked whether a similar effect would occur in the context of simulated vehicles in a visual…

Children are ubiquitous imitators, but how do they decide which actions to imitate? One possibility is that children rationally combine multiple sources of information about which actions are necessary to cause a particular outcome. For instance, children might learn from contingencies between action sequences and outcomes across repeated…

Williams syndrome (WS) is a genetic disorder associated with severe visuospatial deficits, relatively strong language skills, heightened social interest, and increased attention to faces. On the basis of the visuospatial deficits, this disorder has been characterized primarily as a deficit of the dorsal stream, the occipitoparietal brain regions…
