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.

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…

Proposes an object-oriented conceptual data model tailored for organizing and representing basic map elements and their relationships, as well as operations of interest for the management of geographic data. Discussion includes both conceptual abstraction primitives (classification, generalization, and aggregation) and a spatial abstraction…

This study of 65 children (ages 10-13) with dyslexia found no discrete subgroups. Variability in performance on reading tasks was quite similar for the dyslexic and reading age-control groups. A few children with dyslexia resembled phonological dyslexics and surface dyslexics, but these subjects were still part of a continuum. (Author/JDD)

The matching-to-sample performances of three young adults with autism and four children (ages four to nine) without intellectual disabilities were examined in three experiments using complex sample stimuli. Results for all subjects showed that each of two redundant relevant sample elements and their respective comparison stimuli were substitutable…

A series of experiments revealed that noun-category bias in children's word learning is present as early as two years of age. Findings indicate that, when children interpret the meaning of novel nouns, they do not sample randomly from the range of possible meanings but focus instead on category relations. (RH)

The tradition of negotiating indirect costs in grants should be abandoned, and research administrators should instead offer different levels of service depending on what the sponsor wants to spend. Three levels of overhead rate are suggested (super, regular, and economy) and their corresponding levels of service are defined. (MSE)
