To determine how early "the stuttering stereotype" is assigned, 160 university students rated a hypothetical vignette depicting either a 3-, 4-, 5-, or 6-year-old with or without the statement "He stutters". A factor analysis of the semantic differential scale showed a three-factor solution comprised of 17 of the 25 bi-polar adjective pairs. The…

I describe how data pooling and data visualization can be employed in the first-semester general chemistry laboratory to introduce core statistical concepts such as central tendency and dispersion of a data set. The pooled data are plotted as a 1-D scatterplot, a purpose-designed number line through which statistical features of the data are…

This article describes selected results from the Math Online (MOL) study, one of three field investigations sponsored by the National Center for Education Statistics (NCES) to explore the use of new technology in NAEP. Of particular interest in the MOL study was the comparability of scores from paper- and computer-based tests. A nationally…

As people head further into the 21st Century, they are living in a constantly changing and interdependent world. As such, students need a global awareness that includes familiarity with different cultures, beliefs, and lifestyles in order to understand and address global issues. Geography can help students understand these issues. In this article,…

This study examined the effect of social familiarity on salivary cortisol and social anxiety/stress for a sample of children with high-functioning autism spectrum disorders. The relationship between self-reported social anxiety/stress and salivary cortisol was also examined. Participants interacted with a familiar peer on one occasion and an…

Three experiments with short-term recognition tasks are reported. In Experiments 1 and 2, participants decided whether a probe matched a list item specified by its spatial location. Items presented at study in a different location (intrusion probes) had to be rejected. Serial position curves of positive, new, and intrusion probes over the probed…

As we enter deeper into the 21st Century, there is a more urgent need to transform our educational system in the United States to better prepare our youth for the careers and technology of the future. This study examines how improving technology education at the high school level can improve the learning and college readiness of urban youth. It…

This study examined the perception of the four Mandarin lexical tones by Mandarin-naive Hong Kong Cantonese, Japanese, and Canadian English listener groups. Their performance on an identification task, following a brief familiarization task, was analyzed in terms of tonal sensitivities (A-prime scores on correct identifications) and tonal errors…

In the remember-know paradigm, subjects report the subjective basis for their "old" response to a memory probe to be either recollection of specific details ("remembering") or familiarity ("knowing"). The response rates for these judgments are often taken as direct measures of underlying processes, but this process-pure account is implausible in…

Little is known about the effects of listener characteristics or listening conditions on intelligibility scores. This study compared intelligibility scores of dysarthric speech achieved under a standard listening condition with those obtained in non-standard conditions and investigated the effect of listener age, gender and familiarity with…

Familiarity is thought to aid listeners in decoding disordered speech; however, as the speech signal degrades, the "familiarity advantage" becomes less beneficial. Despite highly unintelligible speech sound production, many children with dysarthria vocalize when interacting with familiar caregivers. Perhaps listeners can understand these…

Performance on the visual paired-comparison (VPC) task has typically been interpreted with E. Sokolov's (1963) comparator model of the orienting response; novelty preferences are interpreted as evidence of retention, whereas null preferences are interpreted as evidence of forgetting. Here the authors capitalized on the verbal nature of human…

Setting examination questions in real-world contexts is widespread. However, when students are reading contextualized questions there is a risk that the cognitive processes provoked by the context can interfere with their understanding of the concepts in the question. Validity may then be compromised. We introduce the concept of "focus":…

The authors investigated whether anomalous information in the periphery of a scene attracts saccades when the anomaly is not distinctive in its low-level visual properties. Subjects viewed color photographs for 8 s while their eye movements were monitored. Each subject saw 2 photographs of different scenes. One photograph was a control scene in…

The testing effect, or the finding that taking an initial test improves subsequent memory performance, is a robust and reliable phenomenon--as long as the final test involves recall. Few studies have examined the effects of taking an initial recall test on final recognition performance, and results from these studies are equivocal. In 3…
