Implications of difficulties in using intuitive statistical reasoning are considered as they bear on the theoretic model viewing persons as intuitive scientists who make causal attributions in everyday life. Data sampling strategies and use of judgment rules to identify covariant events were investigated in two studies. Using a rule-analytic…

In a step toward creating a robust natural language understanding system which detects and avoids miscommunication, this artificial intelligence research report provides a taxonomy of miscommunication problems that arise in expert-apprentice dialogues (including misunderstandings, wrong communication, and bad analogies), and proposes a flexible…

A study of the relationship of bilingualism to personality traits focused on two questions: (1) are any language-associated differences between memory systems in bilinguals reflected in similar differences in personality structures?; and (2) if such differences exist, can they be tapped by comparing responses to personality-evoking stimulus in the…

This paper describes the future perspectives of biocybernetic communication research applied to television, i.e., the measurement of the information impact of television on both individual human beings and groups in terms of energetic changes in the human body. A summary of the recent state of the art of biocybernetic research includes discussions…

The monograph addresses the issue of research on learning disabilities (LD) and proposes directions for research in Iowa by means of four articles, a report of a survey of needed research, and six brief response papers. The first paper, "Issues on the Identification of Learning Disabled Children" (S.W. Ehly), discusses the problems of…

Although law professors often say that first year law students need training to "think like lawyers," many law students survive law school by practicing the "skill" of rote memory. It is when they take the bar examination or actually begin to work in a law office that they need the faculty of analytical thinking, for notes must…

The purpose of this paper is to review the relevant evidence concerning the relationship between knowledge and its effect on learning, with an end to answering the questions: (1) How important is knowledge to learning? and (2) How does the relative importance of knowledge change with development? The paper is divided into three main sections:…

In order to accurately assess the learning of vocabulary words, a criterion of learning achievement must be set for each word or group of words. This criterion would reflect: (1) the amount of semantic, grammatical, and phonological information the learner had to possess in order to have learned the word; (2) the receptive and productive processes…

Based on the idea that inference abilities are essential to comprehension, this essay discusses systematic oral questioning strategies designed to help both junior and senior high school teachers develop students' reading comprehension abilities.
