The mood-dependent retrieval hypothesis states that mood will enhance recall by acting as a recall cue if the stimuli have been learned initially in the same mood. Material learned in a happy mood will be best recalled when the person returns to a happy mood; the same holds for a sad mood. Mood-dependent retrieval effect has been regulary…

This paper addresses a variation of the traditional validity question asked of qualitative researchers. Here the question is not "How do we know the qualitative researcher's question is valid?" but rather, "How does the qualitative researcher choose from among a multitude of apparently valid or at least plausible…

Adopting the position, expressed by A. P. Bochner in his critique of small group communication research, that placing measurement in a secondary role increases the danger of accepting the claims of experiments with excessive error, this paper examines nine current quantitative small-group communication studies. Using a schema developed by J. F.…

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…

Criticizes an earlier essay that questioned the validity of contemporary educational research practices, especially those involving experimentation. Argues that research using experimentation is valid and can lead to new and generalizable knowledge. (FMW)

Qualitative research evokes rather stereotyped responses from the mainstream of social science. The following 10 standardized responses to the stimulus "qualitative research interview" (QRI) are discussed: (1) it is not scientific, only common sense; (2) it is not objective, but subjective; (3) it is not trustworthy, but biased; (4) it is not…

This study develops a three-stage model of the question-answering process and investigates several potential sources of extraneous variability. Discussion includes implications of findings concerning what it means to "use" library materials and services, adverbs used as response category labels, and subject's responses as predictors of…

This commentary on EC 602 595 questions cognitive referencing's validity as a model for allocating special services to young children with disabilities. The paper raises methodological issues in studies supporting use of the cognitive referencing model. These issues include the construct of delayed development, subject description, and use of a…

This commentary responds to a critique (EC 601 711) of a paper (EC 211 387) concerning use of cluster analysis to develop a taxonomy of lifestyles of families with severely mentally retarded children. The commentary considers the model to be useful in social science inquiry, and properly validated when using cluster analytic techniques. (JDD)

Arguing that reliable and valid dropout rate estimates are prerequisite to establishment of causal factors and intervention programs, this article examines differences in definitions of dropouts, computational methods, and the complexities in defining cohorts, as well as the importance of sample attrition. Several sources of error are discussed.…

This paper responds to a 1992 study in which it was argued that the structure of intelligence in adults with severe mental retardation deviates from Greenspan's model, in which social and practical intelligence form separate factors. Application of confirmatory factor analysis to the original correlation matrix found the Greenspan model to be…

This paper discusses inconsistencies in Greenspan and McGrew's argument that confirmatory, rather than exploratory, factor analysis should be utilized in testing Greenspan's model of adaptive intelligence in adults with severe mental retardation. It is argued that problems with the data set should be addressed through further research rather than…

Researchers conducted surveys of public attitudes in two Tennessee school systems in 1984-85 and 1985-86. Although interested in the survey results, one purpose of the researchers was to determine some inexpensive and relatively simple survey procedures. The researchers sought--through several pilot studies--to identify an efficient, parsimonious…

A year-long case study of the effects of an educational and vocational rehabilitation program in a youth training center was discussed in terms of fourteen issues which might threaten the validity of an evaluation or research project. This correctional institution housed women aged 14 to 21 who were long-term wards of the state, held on remand, or…

Empirical validation of the Self-Identity Development Model of Oppressed People (SIDMOP) prompted the choice of a multi-methodological approach that would test the underlying theory and not the participants' ability to perform a matching task. Few identity developmental models of oppressed people have been systematically developed, and even fewer…
