This paper examines students' performance in Non-verbal Intelligence tests relative academic achievement of some selected secondary school students. Two hypotheses were formulated with a view to generating data for the ease of analyses. Two non-verbal intelligent tests viz: Raven's Standard Progressive Matrices (SPM) and AH[subscript 4] Part II…

To provide a differentiated characterization of autistic children's logical deficits, a non-verbal, microanalytic method designed for infants and young children was used. Subjects were 12 autistic children ranging in age from 5 to 7 years and a control group of 12 normal children ranging in age from 23 to 30 months. Subjects were given two…

A unique psychometric device, The "Lock Box," has been developed to measure the ability of preschool children to structure a novel problematic situation. The primary purpose of the box is to identify those preschoolers with mental ages ranging from 2 1/2 to 6 years who have difficulty imposing an orderly plan on their explorations and…

The extent to which human facial expressions are universal and cross-culturally recognizable has been the subject of considerable debate. Two approaches have been used in studies of facial expressions: the judgment approach entails showing examples of facial expressions to various cultures or groups of people and determining whether they interpret…

In this study, cognitive processes hypothesized to be relevant to the digit symbol task of the Wechsler Adult Intelligence Scale (WAIS) were examined. Fifty-two undergraduate education students were divided into four groups to receive four different treatments. All the students took the digit symbol test, followed immediately by a test of their…

The Stanford-Binet (Fourth Edition) (S-B:FE) and Kaufman Assessment Battery for Children (K-ABC) were administered in counterbalanced order to a sample of 30 non-handicapped, preschool children (13 males and 17 females). The children ranged in age from 3 years 11 months to 6 years 2 months, with a mean age of 4 years 11 months. Mean scores on the…

It was wished to determine the relative reliabilities of graphic and semantic differential factors to evaluate applicability of two rival models to the measurement of pupil attitudes. Data was collected from a sample of sixth grade pupils on both abstract graphic and typical semantic differential scales. Reliability estimates were constructed from…

The Key Assessment System, consisting of test instruments which measure psychological functioning, work related competencies, and attitudinal and motivational characteristics, is described. The system is a vocational assessment battery designed to differentiate levels of psychophysical capabilities in a nondiscriminatory manner. It provides a…

A study investigated developments in reasoning and memory as reflected by the discovery strategies of children taking part in a manipulative categorization and recall task. A total of 40 children (8 each of 18, 24, 30, 36, and 42 months of age) participated. Stimulus materials consisting of blocks, toy plates, discs, and plastic trees were…

The Aircraft Instrument Comprehension (AIC) Program is a self-instructional program designed to teach undergraduate student pilots to read instruments that indicate the position of the aircraft in flight, based on sequential instructional stages of information, prompted practice, and unprompted practice. The program includes a 36-item multiple…

The effects of modeling and corrective feedback on the conservation of equalities and inequalities were studied with items spanning three stimulus dimensions (length, number, and two-dimensional space). Observation of a model, correction training (joining positive feedback with verbal rule provision), and the combination of observation and…

Investigates several instruments measuring intelligence and prior conceptual knowledge/achievement to determine how well they predict outcomes in computer assisted language learning. Concludes that a non-verbal intelligence test was a significant predictor, but that prior conceptual knowledge of course content was low. Level of prior achievement…

This study probed whether or not a distinctive Down syndrome (DS) pattern could be found in the realm of vocabulary comprehension. Groups of 29 each of DS adolescents, non-DS mentally retarded (MR) adolescents, and nonretarded children were statistically matched on receptive vocabulary ability; DS and MR groups were also matched for chronological…

Aspects of children's early representational drawing ability may provide evidence for feature marking in non-linguistic symbol systems. To test this assumption children in kindergarten, second, and fourth grade were asked to draw a set of referent objects in three conditions: a nominal or standard condition with no implied relationship ("two…

The paper describes the application of discriminant analysis to the identification of academically gifted elementary grade students. The principles of discriminant analysis are explained to provide a weighted profile of scores across predictor variables which are then compared with a criterion measure. An illustration of the method's used with 64…
