Examines fundamental questions about how people process numbers. Several cognitive numerical representations are defined. The current major theories of numerical cognition are described with emphasis on how they differ in their assumptions about numerical representations and how these differences are reflected in the positions taken on various…

Compared subjects' judgments about emotions expressed by the faces of infants pictured in slides to predictions made by the Max system of measuring emotional expression. Judgments did not coincide with Max predictions for fear, anger, sadness, and disgust. Results indicated that expressions of negative affect by infants are not fully…

Analyzes the amount of compression possible when arithmetic coding is used for text compression in conjunction with various input models. Algorithms are analyzed; modeling effects are considered; scaling is discussed; higher order models are examined, including prediction by partial matching; and coding effects are described.

Examines two models to study the consequences for coding efficiency of sample fluctuations, a specific type of error in the statistics on which data compression codes are based. The possibility that random fluctuation can be exploited for data compression is discussed. (six references) (KRN)

This paper examines the need for a transcription system that allows the symbolization of nonnormal articulations. The paper then describes transcription systems proposed by clinical phoneticians and speech pathologists, especially PRDS (phonetic representation of disordered speech) symbols and extensions of the International Phonetic Alphabet.…

A coding method for measuring reflective thinking in student journals was tested twice, demonstrating acceptable reliability among evaluators and supporting the precision of the guidelines for coding. Coding categories were as follows: habitual action, introspection, thoughtful action, content reflection, process reflection, content and process…

At 2 sites information was collected from 168 workers, and their 3-letter Holland work environment codes were crossed with 3 measures of person-environment congruence. All three measures were strongly intercorrelated. The way a job was coded had a significant effect on the calculation of congruence. (SK)

Description of integrating one of the most widely used cryptosystems into a mathematics course for Liberal Arts majors. Application of this cryptosystem requires understanding of the concepts of exponentiation and modular arithmetic only. (MM)

Consistent with converging experimental evidence, we assume that foveal information is initially split across the two cerebral hemispheres. We have previously presented the SERIOL model of letter-position coding, which specifies how the resulting two halves of a letter string are integrated into an abstract representation of letter order. This…

Three experiments are reported that examined whether stem complexity plays a role in inflecting polymorphemic words in language production. Experiment 1 showed that preparation effects for words with polymorphemic stems are larger when they are produced among words with constant inflectional structures compared to words with variable inflectional…

An understanding of the relationships among the integration of computer technology by women educators in higher education and effective teaching could have a significant impact on education. Pennsylvania Universities and Colleges have made their commitment to educational technology and provided support for the implementation of such technology.…

Quantitative content analysis is increasingly used to surpass surface level analyses in computer-supported collaborative learning (e.g., counting messages), but critical reflection on accepted practice has generally not been reported. A review of CSCL conference proceedings revealed a general vagueness in definitions of units of analysis. In…

The concept of congruence between person and occupation lies at the core of Holland's (1997) theory of career types. The C index is arguably the best available method for comparing the congruence of two Holland code profiles. The C index reflects the theorized hexagonal structure of the Holland RIASEC model, is sensitive to code ordering, and is…

This study examined the sexual messages depicted in music videos aired on MTV, MTV2, BET, and GAC from August 2, 2004 to August 15, 2004. One-hour segments of music videos were taped daily for two weeks. Depictions of sexual attire and sexual behavior were analyzed via a four-page coding sheet (interrater-reliability = 0.93). Results indicated…

Based upon the lessons learned and the educational materials generated from a doctoral course on qualitative data analysis, a group of doctoral students, their professor, and a linguistics consultant launched an on-going project to create a series of reusable learning objects designed to help other groups of students and professors learn how to…
