When one learns complex material, the important thing appears to be the ability to understand the material. Once understanding occurs, learning and remembering follow automatically. The conventional psychological literature says little about the processes involved in the learning of complex material--material that takes weeks, months, and even…

Selected cognitive developments presumed to mediate the development of achievement motivation are described. Age trends for four causal schemes involving the concepts of effort and ability from 5 to 13 years of age are presented. Developments related to ability, task difficulty, and incentive value are also described. (Author/JMB)

Two techniques for writing achievement test items to accompany instructional materials are contrasted: writing items from statements of instructional objectives, and writing items from semi-automated rules for transforming instructional statements. Both systems resulted in about the same number of faulty items. (Author/JKS)

Proposes explanations and further research considerations for the apparent psychological equivalence of the terms "complexity" and "novelty" as they refer to information theory, stimulus generalization, and subject expectancy effects. (RL)

This study explore possible explanations for the decline in highly creative contributions in old age. Examined are the role of decrements in specific divergent thinking abilities and the decline in preference for complexity as factors in the decline in creative contributions. (BD)

Because disabled learners may profit from procedures using gradual stimulus change, this study utilized a microcomputer to investigate the effectiveness of stimulus equalization, an error reduction procedure involving an abrupt but temporary reduction of dimensional complexity. The procedure was found to be generally effective and implications for…

The influence of three variables on response to undecidability was studied: (1) dual- versus single-solution rules; (2) nature of the choice contrast, and (3) presence or absence of additional information to resolve the undecidability. Participants were college students and third, fourth, and fifth grade elementary school students. (RH)

Investigated effects of changing the level of motor planning demands in simple drawing tasks for which children aged 5-11 years completed or copied squares and diamonds. Results were consistent with previous studies. Low planning demands resulted in less difference between square and diamond performance than did tasks demanding higher planning.…

This paper describes three interactive computer programs used with personal computers to present science learning modules for all ages. Developed by groups of teachers at the Educational Technology Center at the University of California, Irvine, these instructional materials do not use the techniques of contemporary artificial intelligence.

This article studies the effects of complexity and completeness in an introductory psychology textbook on students' understanding of the text materials. It was found that students presented with oversimplified versions made incorrect references. Complex presentation, however, did not adversely affect the students' test responses. (JAZ)

Explores 96 preschool children's utilization of complementary and taxonomic relations under varying task demands. Results indicated that, as task demands increased, (1) complementary intrusions produced systematic error in the taxonomic condition and (2) performance decreased in both conditions. Complementary pairs were maintained at progressively…

This personal reaction to Cummings'"Comparison of Three Algorithms for Analyzing Questionnaire-Type Needs Assessment Data to Establish Need Priorities" specifically questions Cummings' use of the Mean Difference Analysis for comparison with Weighted Needs Index, and his focus on characteristics of the statistic that are of secondary…

The analytical decomposition demonstrates how the effects of item characteristics, test properties, individual examinee responses, and rounding rules combine to produce the item deletion effect on the equating/scaling function and candidate scores. The empirical portion of the report illustrates the effects of item deletion on reported score…

For the purpose of obtaining data to use in test development, multiple matrix sampling plans were compared to examinee sampling plans. Data were simulated for examinees, sampled from a population with a normal distribution of ability, responding to items selected from an item universe. (Author/LMO)
