Describes a new data compression technique that utilizes the common morphological structure of languages. Topics include classification of languages and their morphological structure; structured text compression; the algorithm and an example using Turkish; theoretical implications; and implementation.

Fifty-two undergraduates completed a questionnaire identifying 40 acquaintances, from which 4 were picked systematically from the list. Role descriptions for the four acquaintances, ratings of their relationships, and characteristics of the relationships were assessed. Found evidence for the existence of truly discrete cognitive forms of social…

Three experiments compared the assignment of gender to masculine and feminine pictured objects as classified by Spanish grammatical gender, by English- and Spanish-speaking children, and by adults. Results revealed artificial-male/natural female conceptual division among speakers of English and delayed effects of grammatical gender among speakers…

Describes investigation utilizing sickle cell disease subjects from a stress and coping project. Found little stability in classification of individuals' adjustment, low congruence in behavior problem patterns and diagnoses, and less stability in adjustment by child report than mother report. Suggests children's coping strategies are intervention…

Factors affecting the development of a taxonomy of psychopathology for children with mental retardation are considered, along with the following diagnostic areas to address: stereotypic behavior and self-injury, autism, organic brain syndromes, and pervasive developmental disorders. Using data from multivariate studies and findings related to…

Five three-year-old children with disabilities were taught to identify rebus symbols. Children were given praise and instructive feedback. All children learned to identify all symbols. They acquired second and third sets of stimuli faster than they acquired the first set. (LB)

The definition of mental disorder in the third edition of the "Diagnostic and Statistical Manual of Mental Disorders" (DSM-III-R) explains that a disorder is harmful and represents a dysfunction, but it fails to capture the idea of dysfunction. Ideas for increasing the conceptual validity of the definition are presented. (SLD)

The importance of phonology in assigning words to the correct grammatical category in language processing is discussed. Correlations between phonology and grammatical class are discussed. Experiments demonstrating that adults and children have learned these correlations are proposed and evaluated. (SLD)

Tested 7 and 10 month olds for perception of correlations among facial features. After habituation to faces displaying a pattern of correlation, 10 month olds generalized to a novel face that preserved the pattern of correlation but showed increased attention to a novel face that violated the pattern. (BC)

This paper considers meanings used for the terms "affect,""emotion," and "mood" and suggests that feeling states should be defined in terms of duration, subjectivity/objectivity, the role of cognition, and the phenomenological level. A study of patients' facial expression and vocal acoustics is described to offer empirical support for the…

Presents a rock classification scheme for use by beginning students. The scheme is based on rock textures (glassy, crystalline, clastic, and organic framework) and observable structures (vesicles and graded bedding). Discusses problems in other rock classification schemes which may produce confusion, misidentification, and anxiety. (10 references)…

S. Glucksberg and B. Keysar's (1990) class-inclusion view of metaphor understanding does not properly acknowledge metaphor's role in everyday cognition. Metaphor is a powerful scheme in long-term memory by which people make sense of their experiences. Evidence supports tacit conceptual metaphor's role in comprehension of verbal metaphors in…

Reviews models of staff development in British higher education. Five micro models of staff development practice are described and evaluated; three macro models of staff development responsibility are identified; relationships between micro and macro models are discussed; and the most suitable models are suggested.

Explains methods for the survey, classification, and mapping of the visual characteristics of landscapes, independently from the subjective aspects of perception. (Contains 18 references.) (Author/MDH)

A methodology is proposed to optimize the training classification performance of any suboptimal model. The method, referred to as univariate optimal discriminant analysis (UniODA), is illustrated through application to a two-group logistic regression analysis with 12 empirical examples. Maximizing percentage accuracy in classification is…
