I used a subscriber identity module card reader to copy the lists of saved contacts from 170 mobile phones in Fiji. This approach has both advantages and disadvantages compared to other techniques for collecting telephone network data. Copying phone contacts avoids recall biases associated with survey-based name generators. It also obviates the…

Discussed are limitations of studies focused on group data and some alternative conventions that might be used in reporting data so that it accurately represents individual subjects' patterns of language development. Evidence is presented from (1) a study of mothers' attempts to elicit verbal behavior from their normally developing or moderately…

Paper considers some of the problems facing the researcher interested in patterns of abilities as revealed by a discussion of the Lesser studues (1971), presentation of reanalyses of their data, and a critical review of the research. (Author/CB)

Introduces the "person approach" to the study of adolescence, and discusses the consequences of the approach for theoretical thinking and research methodology. Reviews major types of pattern-based methods used for carrying out a person approach and discusses methodological challenges for adolescent research, including interindividual…

The data analysis problem posed by a repeated measures design that includes a single observation on a covariate for each subject is considered. The current paper discusses how best to capture a possible dependence of the effect of the within-subject factor on the level of the covariate. Procedures originally explicated by Rogosa (1980) for dealing…

The concept of "multi-dimensionality" which attempts to explain differences between social classes in Lipset's formulation, has suffered from confusion regarding the level of analysis (individual or social class). In this study of college students, the multi-dimensional concept of political liberalism-conservatism was found to be unwarranted on…

Argues that individual and group differences in priming performance scores are heavily influenced by overall speed and accuracy, and thus are a flawed reflection of internal activation of semantic priming. Suggests that meaningful comparison of groups on the activation underlying priming difference scores requires removing the effects of overall…

When two groups, initially dissimilar, undergo different treatments, can subsequent differences be partitioned in such a way that the difference between the two treatments is unbiased? This is the central problem of this paper, and it is confronted by the examination of two levels of information using a Follow Through Evaluation. The first…
