Data from a 20-year longitudinal study of persons over 60 were analyzed by step-wise multiple regression to test for declines in function with age, for terminal decline (linear relationship to time before death), and for terminal drop (curvilinear relationship to time before death). There were no substantial terminal drop effects. (Author)

This study indicated that the school performance and intelligence quotients of associative responders diverge significantly over time from those of nonassociative responders. This divergence becomes greater with age, suggesting that reliance on associative responding in preference to reasoning may cumulatively interfere with intellectual…

Paper presents a mathematical framework which describes an aspect of the means of communication between a physical system in motion and a sequential logic network. (Author)

Recent developments in artificial intelligence and decision analysis suggest reassessing the approaches commonly taken to the design of knowledge-based systems. Competent systems are based on models known as influence diagrams, which graphically capture a domain's basic objects and their interrelationships. Among the benefits offered by influence…

The expansion of human potential and the accompanying increase in self-esteem and self-actualization is the key to emotional and physical health, social relations, learning problems, self-discipline, and future survival. Self-knowledge, obtained through such measures as keeping records of moods and through biomechanical devices, can enable…

The paper describes an approach to developing systematic procedures for identifying handicapped children that leads to rational decisions regarding placement. An expert system is described which involves the user in a dialogue on data regarding individual children; this dialogue is similar in many ways to a consultation with an expert. After…

While verbal language has traditionally determined our view of intelligence, this limited view ignores other systems for expressing intelligent thought. An expanded concept of language considers verbal language as one part of a mental modeling system, or internal representation, for any kind of sensory information available to us, visual or…

This monograph contains two studies in which the notion of intelligence as one general basic ability is rejected and in its place is posited the existence of a specific type of mental ability described as "spatial intelligence.""Spatial Reasoning and Its Measurement" investigates the process of spatial reasoning in the adult through an analysis of…

"The Sourcebook," a database of exemplars of representative problems in natural language understanding, is being developed for use in evaluating natural language processing systems. A literature search of the computational linguistics literature was used to identify the exemplars, which are analyzed in terms of the general issues…

This study investigated novice and expert problem solving behavior in management to examine the role of domain specific knowledge on problem solving processes. Forty-one middle level marketing managers in a large petrochemical organization provided think aloud protocols in response to two hypothetical management scenarios. Protocol analysis…

The Wechsler Intelligence Scale for Children--Revised (WISC-R) Freedom from Distractibility (FFD) factor and other neurocognitive measures were examined as to their discriminative validity in diagnosing children with Attention Deficit Disorder/Hyperactivity (ADD/H), ADD/H children with concurrent Conduct Disorder, and children comprising a clinic…
