Researchers studied the interaction of college students with Piagetian tasks on microcomputers and found that the microcomputer system provided several advantages over the original tasks, as well as new alternatives for studying logical thinking processes. An example of a programed Piagetian task is appended, and 16 references are included. (MER)

Results of study investigating human memory organization in processing of computer programming languages indicate that algorithmic logic segments form a cognitive organizational structure in memory for programs. Statement indentation and internal program documentation did not enhance organizational process of recall of statements in five Fortran…

The dangers of overlooking time-honored cautions in the making causal interpretations of data analyses from correlational studies when using highly sophisticated computer programs and their associated techniques are discussed. (JKS)

Discusses the role of computer programs which have shaped the development of methodology in psychology. Developments in general statistical inference, data analysis, multivariate methods, measurements, and mathematical models of behavior are described. (KC)

The choice of the clustering method, the similarity measure, the computer program, and the procedure for estimating the number of clusters should be clearly specified in any journal article using cluster analysis. Adequate evidence of a cluster solution's validity should be provided before the solution is published. (Author)

A method is developed for testing a priori multiple regression models. The method allows one to specify in advance as many unstandardized or standardized coefficients as one wants to and allows the remaining slopes to be free to vary. (Author/PN)

Reported is a method for the analysis of qualitative data, based on the linguistic device of systemic networks used to represent a structure of possibilities. Some initial applications are described, and work in progress, including a computing system, is outlined. (Author/HM)

The effectiveness of a computer-assisted training method using computer simulation of two subsets of the Wechsler Intelligence Test for Children--Revised was compared with traditional methods for teaching the administration of the test. Results suggest that the computer simulation was a very effective teaching method. Eleven references are listed.…

Controlled experiments conducted to compare effectiveness of enhanced experimental computer intermediary system, CONIT, with that of human expert intermediary search specialists indicate that experimental intermediary techniques are now capable of providing search assistance whose effectiveness at least approximates that of human intermediaries in…

Describes British Library's work on Systems Dynamics, a set of techniques for building simulation models based on analysis of information feedback loops. Highlights include macro-simulation modelling activities of social science disciplines, systems analyses and models of information retrieval processes and library services, policy models, and…

Students in experimental group received continuous feedback on learning performance and were allowed to make instructional decisions to determine whether learner control of instruction can be facilitated by directly affecting the student's perception of learning need. Results are discussed in reference to an information-processing approach to the…

The development of a low cost input system is discussed in terms of the appropriateness of imposing program-controlled answering strategies on candidates attempting a conventional multiple choice objective question achievement test. Systems used for the management of learning and strategies students use to answer tests are highlighted. (Author/EJS)
