Purpose: Four functional hearing loss protocols were evaluated. Method: For each protocol, 30 participants feigned a hearing loss first on an audiogram and then for a screening test that began a threshold search from extreme levels (-10 or 90 dB HL). Two-tone and 3-tone protocols compared thresholds for ascending and descending tones for 2 (0.5…

Purpose: Studies investigating the ability of children with language impairment (LI) to infer emotions rely on verbal responses (which can be challenging for these children) and/or the selection of a card representing an emotion (which limits the response range). In contrast, a drawing task might allow a broad spectrum of responses without…

Purpose: This study presents data from 2 families with high incidence of stuttering, comparing methods of phenotype assignment and exploring the presence of other fluency disorders and corresponding speech characteristics. Method: Three methods for assigning phenotype of stuttering were used: self-identification, family identification, and expert…

Purpose: The production of formulaic expressions (conversational speech formulas, pause fillers, idioms, and other fixed expressions) is excessive in the left hemisphere and deficient in the right hemisphere and in subcortical stroke. Speakers with Alzheimer's disease (AD), having functional basal ganglia, reveal abnormally high proportions of…

If the end of a long chain, which is contained in an elevated beaker, is dropped over the edge of the beaker and falls, it is observed that as the speed of the chain increases the chain rises to form a loop well above the top of the beaker. The name "chain fountain" has been applied to this phenomenon. In this study the dependence of the…

We compare teacher preparation programs in Missouri based on the effectiveness of their graduates in the classroom. The differences in effectiveness between teachers from different preparation programs are much smaller than has been suggested in previous work. In fact, virtually all of the variation in teacher effectiveness comes from…

The idea of happiness boomed in the public as well as in the academic domain over the last decade and has not reached its peak yet. However, the understanding of happiness (understood as eudaimonia) as being the utmost goal of human beings is hardly new. Philosophers have discussed this topic, under various terms, throughout history. One of the…

Research increasingly emphasizes understanding differential effects. This article focuses on understanding regression mixture models, which are relatively new statistical methods for assessing differential effects by comparing results to using an interactive term in linear regression. The research questions which each model answers, their…

One approach to validating assessment scores involves evaluating the ability of scores to discriminate among groups who differ in a specific characteristic, such as training status (in education) or disease state (in clinical applications). Such known-groups comparison studies provide validity evidence of "relationships with other…

Constructivism and constructionism are two distinct epistemologies. Yet, within religious education many have tended to use these terms interchangeably or as being complementary to one another. This article provides conceptual clarity in relation to both epistemologies by comparing each in terms of their origins and epistemological premises, their…

Using econometric analysis on survey data from European-born and European-educated researchers who are internationally mobile after their PhD within Europe or to the United States, we find significant positive effects from international mobility on scientific productivity, as well as several other positive career development effects. European…

Noradrenaline contributes to olfactory-guided behaviors but its role in olfactory learning during adulthood is poorly documented. We investigated its implication in olfactory associative and perceptual learning using local infusion of mixed a1-ß adrenergic receptor antagonist (labetalol) in the adult mouse olfactory bulb. We reported that…

Research on creative artists has examined mainly their personality traits or cognitive abilities. However, it seems important to explore also their emotional traits to complete the profile. This study examines two emotional characteristics: alexithymia and affect intensity. Even if most research suggests that artists are less alexithymic and…

This article reports on a qualitative study that uses a phenomenological approach to investigate the differences between adolescents with high and low career adaptability levels, regarding adaptive strategies and needs. The sample included students categorized as above the 75th percentile and in the bottom 25th percentile according to their scores…

Open-ended tasks are common in Science, Technology, Engineering and Mathematics (STEM) education. However, as far as we know, no tools have been developed to assist in the assessment of the solution process of open-ended questions. In this paper, we propose the use of analysis of traces as a tool to address this need. To illustrate this approach,…
