The process of learning involves interaction with the learning environment through our five senses (sight, hearing, touch, smell, and taste). Until recently, distance education focused only on the first two of those senses, sight and sound. Internet-based learning environments are predominantly visual with auditory components. With the advent of…

One of the strong trends in medical education today is the integration of the humanities into the basic medical curriculum. The anatomy program is an obvious choice for using the humanities to develop professionalism and ethical values. They can also be used to develop close observational skills. Many medical schools have developed formal art…

Participants searched a visual display for a target among distractors. Each of 3 experiments tested a condition proposed to require attention and for which certain models propose a serial search. Serial versus parallel processing was tested by examining effects on response time means and cumulative distribution functions. In 2 conditions, the…

Thematically related concepts like "coffee and milk" are judged to be more similar than thematically unrelated concepts like "coffee and lemonade". We investigated whether thematic relations exert a small effect that occurs consistently across participants (i.e., a generalized model), or a large effect that occurs inconsistently across…

This article examines the extent of differences between second language (L2) learners in their abilities to identify L2 consonants and provides evidence for linguistic generalization from one consonant to other consonants. It distinguishes among different sorts of models of the relationship between segments: (a) "segmentally specific models" in…

This dissertation examines the relationship between the structural, phonemic properties of vowel inventories and their acoustic phonetic realization, with particular focus on the adequacy of Dispersion Theory, which maintains that inventories are structured so as to maximize perceptual contrast between their component vowels. In order to assess…

The musical priming paradigm has shown facilitated processing for tonally related over less-related targets. However, the congruence between tonal relatedness and the psychoacoustical properties of music challenges cognitive interpretations of the involved processes. Our goal was to show that cognitive expectations (based on listeners' tonal…

Pigeons were trained on two temporal bisection tasks, which alternated every two sessions. In the first task, they learned to choose a red key after a 1-s signal and a green key after a 4-s signal; in the second task, they learned to choose a blue key after a 4-s signal and a yellow key after a 16-s signal. Then the pigeons were exposed to a…

All of the data reported in Robilotto, Khang, and Zaidi (2002) Robilotto and Zaidi (2004), and Singh and Anderson (2002) are consistent with Robilotto and Zaidi's theory that perceived transparency (or opacity) is determined by the perceived contrast of the filter region. Kasrai and Kingdom's (2001) results also appear largely consistent with the…

In M. Singh and B. L. Anderson, the authors proposed a model based on ratios of Michelson contrasts to explain how human observers quantitatively scale the perceived opacity of transparent surfaces. In subsequent work by B. L. Anderson, M. Singh, & J. Meng, the authors found that this model failed to generalize to other contexts and replaced it…

This study investigated the effects of first language prosodic transfer on the perception and production of English lexical stress and the relation between stress perception and production by second language learners. To test the effect of Thai tonal distribution rules and stress patterns on native Thai speakers' perception and production of…

Speech perception requires the integration of information from multiple phonetic and phonological dimensions. Numerous studies have investigated the mapping between multiple acoustic-phonetic dimensions and single phonological dimensions (e.g., spectral and temporal properties of stop consonants in voicing contrasts). Many fewer studies have…

This study, using the "Superintendent Efficacy Questionnaire" (Devono, Diaz & Callejo Perez, 2008), compared 413 West Virginian K-12 superintendents', principals' and teachers' perceptions of 6 superintendent leadership components: staff development administration, communication of mission, curriculum/instruction expertise,…

Speech perception and speech production were examined in 3-year-old Dutch children at familial risk of developing dyslexia. Their performance in speech sound categorisation and their production of words was compared to that of age-matched children with specific language impairment (SLI) and typically developing controls. We found that speech…
