If the factor loadings of a core set of variables (fitting the general factor model) are the same when analyzed alone, and when analyzed along with the rest of the variables in an infinite behavior domain, there is only one factor variable in the domain that is a possible factor variable of the core set. If the condition of consistency of factor…

There are several problems associated with research using the schema concept. One problem is that there seems to be a lack of cumulative development, with the research being horizontal in quality, spreading out to new areas. Another problem with schema research is that a person not already convinced of the merit of the schema notion can remain…

The levels of processing framework for understanding memory development has generated little empirical or theoretical work that furthers an understanding of the developmental memory system. Although empirical studies by those testing the levels of processing framework have demonstrated that mnemonic strategies employed by children are the critical…

Results are presented of a survey designed to elicit information from labs and centers on the types of development models that are currently being used in product development efforts and the evaluation strategies or models that have been found to be most compatible with them. The case is made that a great deal of research needs to be conducted on…

Challenges the typical treatment of causal effects in longitudinal data, arguing that models should be conceptualized and tested in ways that directly reflect prior assumptions as to the trait- or state-like nature of the variables. Examples demonstrate that meaningful longitudinal studies of state variables can be conducted without assuming their…

Five dissemination models that may ensure that research findings are translated into practice are described from the literature. Current research findings in seven areas (such as technology, curriculum, and early intervention) related to education for visually handicapped people are summarized, together with recommended dissemination procedures.…

An educational feasibility framework is described which considers constraints to feasibility, sources of data for determining feasibility, and feasibility study methodology. (Author)

In experimentation where change in X produces a change in Y, the researcher must identify, measure, and control intervening variables by experimental design or statistical procedure. (Author)

Discusses articles by Richard Rystrom in the Winter and Spring 1970 issues of the Journal of Reading Behavior. Questions the validation procedures and statistical evidence behind the author's model of reading comprehension. Tables and bibliography. (RW)

Early work by Bartlett in memory theory is contrasted with the more firmly entrenched empirical-associationistic notions of his time. Contemporary lines of research are then discussed within the perspective of this ongoing controversy. A more purely constructive model with active processing during retention, recall, and comprehension is presented.…

Argues that developmental psychologists need attitudes, methods, and conceptual schemes that integrate the distinctive contributions of both nature and nurture in order to study change and consistency in developmental functions, as well as individual differences in behaviors of interest. A conceptual scheme for early mental development is…

Discussion of conceptual and methodological aspects of reading intervention research focuses on nine specific design limitations of previous intervention research; ways to measure and analyze change as a function of development, treatment intervention and ecological influences; assumptions of individual growth models; and advantages, conditions,…

Maintains that progress in understanding reading is impeded when researchers working from different perspectives adopt the assumption of paradigm incompatibility. Argues that this assumption is false, and that progress toward a comprehensive understanding of the reading process would be hastened if investigators from all perspectives agreed to a…
