Argues that although many publications imply that a negative attitude toward older people is common, evidence does not support this judgment. Reports a study in which participants were allowed to give their opinions on the number of exceptions to generalizations about the elderly. Suggests possible motives for misinterpreting evidence.

Argues that social scientists convey the impression of rational behavior by means of self-serving research techniques. Concludes that their artificially constructed order masks the disorder of everyday existence and that they should have tolerance for human frailties. (Author/WD)

Ridge regression offers advantages over ordinary least squares estimation when a validity shrinkage criterion is considered. Comparisons of cross-validated multiple correlations indicate that ridge estimation is superior when the predictors are multicollinear, the number of predictors is large relative to sample size, and the population multiple…

Information processing research offers a solution to the ambiguity of many concepts in cognitive psychology. The author's definition of intelligence and the structure-of-intellect model offer a systematic collection of rigorously and operationally defined concepts. New evidence for discriminability of the model categories and views of memory and…

External and implementation factors and their potential threats to field test validity and the practical realities of the field testing process on results are discussed. External factors include site selection, negotiations, contracts, site monitoring, training, and type of product. Implementation factors include motivation, dependence on local…

Argues that, although Piaget's seminal work on children's use of intention and consequence information to make moral evaluations has spawned a substantial amount of research, progress in this area has been hampered by serious conceptual and methodological problems. Offers some methodological guidelines for conducting research in this area.…

Uses Harold Rosenberg's metaphor and image to suggest that art education researchers have a limited view of the purpose and scope of their field. Dimensions of research and scholarship activities in art education are discussed. (AM)

Some procedures for estimating internal consistency reliability may be superior mathematically to the more commonly used methods such as Coefficient Alpha. One problem is computational difficulty; the other is the possibility of overestimation due to capitalization on chance. (Author/CTM)

Analyzes methods used to record infant head position and the limits of these methods. An experimental device is proposed which records infant head turning and head righting when the vestibular system is stimulated. (Author/DB)

Simple Markov models are fitted to a small sample of longitudinal categorical data of teachers' ratings of children's classroom behavior. Although the data consist only of observations at five occasions, it was possible, after dividing the data into two groups, to fit plausible models in continuous time. (Author/BW)

Identifies significant limitations found in research on smoking behavior including the lack of common definitions of various behaviors, honesty of subject response, the lack of prospective studies, and the preponderance of univariate types of analyses. Presented at the 10th International Conference on Health Education in London, September 1979.…

Many researchers, including Buriel (EJ 187 987), incorrectly compared the results in each study with null hypotheses of zero differences between means or zero population correlations. Instead, a test of difference between the mean differences in the two samples or the direct comparison of the two sample correlations is required. (Author/CP)

The sciences of nutrition and toxicology require deep methodological reexamination. (JD)

The necessity and value of survey research in education as well as accomplishments and difficulties are discussed. (JMF)
