This study, with 26 deaf and 26 pair-matched hearing preschool children, first assessed their cognitive modifiability using dynamic and static-convention instruments, and then compared the factorial pattern of the cognitive measures in both groups. Results are interpreted according to the Structural Cognitive Modifiability and Mediated Learning…

Three experiments focused on the function relating children's response time to adults' response time in corresponding conditions. In all experiments, children's response times increased in a linear manner as a function of adults' response times. (BB)

Relationships between reading comprehension (RC) and critical thinking skills, vocabulary, and cognitive ability were examined using 3 tests with 165 underachieving first-year college students in a remedial reading class. The Iowa Silent Reading Test's vocabulary subtest best predicted RC. The Developing Cognitive Abilities Test's three subtests…

Discussion of human/system interactions that are fundamental to online searching focuses on studies that examined online searchers' performance on DIALOG when they searched specific users' questions. Cognitive tests that were given to searchers are described; and calculating the odds for relevance, precision, and recall is explained. (four…

Procedures that could be used to assess progress in instructional programs designed to enhance cognitive skills are reviewed, discussing measures of the following parameters: (1) knowledge acquisition, organization, and structure; (2) problem representation; (3) mental models; (4) metacognitive skills; (5) automaticity of performance; and (6)…

Two studies with 658 white and 353 African-American elementary school children performing reaction time tasks are offered in support of Spearman's hypothesis about the relative size of the mean African-American-white differences on mental tests as a function of the tests' loadings on psychometric "g." (SLD)

Videoconferencing (VC) technology has been used successfully to provide psychiatric services to patients in rural and otherwise underserved settings. VC-based diagnostic interviewing has shown good agreement with conventional face-to-face diagnosis of dementia in several investigations, but extension of this technology to neurocognitive assessment…

In this study, we defined and quantified the degree of cognitive conflict induced by a discrepant event from a cognitive perspective. Based on the scheme developed, we investigated the relationship between cognitive conflict and conceptual change, and the influences of students' cognitive characteristics on conflict in learning the concept of…

This study examined the relative intellectual impacts of two- and four-year college educational programs by focusing on changes in reading comprehension, mathematics, and critical thinking skills in 204 freshmen students who attended either a public two-year community college near a large metropolitan area or a public four-year, urban research…

The Second Follow-Up Field Test (SFUFT) of the National Education Longitudinal Study of 1988 (NELS:88) was conducted in 1990 and 1991 by the National Opinion Research Center and the Educational Testing Service. The SFUFT evaluated free response items (FRIs) for possible inclusion in the Second Follow-Up Main Study (SFUMS) and tested survey…

This study explored the hearing capabilities of Down Syndrome (DS) adolescents and young adults relative to a matched sample of non-DS trainable mentally handicapped (MH) individuals, and examined the relationship between hearing ability and performance on several cognitive tasks. Samples of 26 DS and 26 MH individuals were matched on intelligence…

Social studies research has told us very little in the past 30 years. There are several reasons for this state of affairs in social studies. First, inferential statistics has become much too prominent in research thinking and practice. Replication should be used by researchers to build a useful body of knowledge. A second reason for lack of…

The California Critical Thinking Skills Test--College Level (CCTST) was examined in terms of the possible impact on critical thinking (CT) skill performance of: (1) student gender; (2) ethnicity; (3) academic major; and (4) CT self-esteem. The CCTST was administered to 1,196 students at California State University (Fullerton) in the 1989-90 school…

The validity of educational tests used as critical measures of educational outcomes within a dynamic system is discussed. Validity becomes a problem if an educational system adapts itself to the characteristics of the outcome measures. The concept of systematically valid tests is introduced; these tests induce curricular and instructional changes…

Group norms are provided for the California Critical Thinking Skills Test (CCTST)--College Level, a standardized 34-item multiple-choice test designed to assess the core critical thinking skills associated with baccalaureate general education. The CCTST offers three subtests conceptualized in terms of a national Delphi study on critical thinking.…
