In "Writing and Reviewing Manuscripts in the Multidimensional World of Qualitative Research" (LaRossa, 2012), the author expressed the hope that, by sketching a cognitive map of the writing and reviewing process, authors and reviewers for the "Journal of Marriage and Family" ("JMF") would be better able to communicate with each other about the…

The purpose of this essay is to draw out key insights from Dewey's important text "Logic: The Theory of Inquiry" to provide theoretical and practical support for the emergent field of teacher research. The specific focal point is the argument in Cochran-Smith and Lytle's "Inside/Outside: Teacher Research and Knowledge" on the significance of…

Lecoutre, Lecoutre, and Poitevineau (2010) have provided sophisticated grounding for "p[subscript rep]." Computing it precisely appears, fortunately, no more difficult than doing so approximately. Their analysis will help move predictive inference into the mainstream. Iverson, Wagenmakers, and Lee (2010) have also validated…

This comment offers three descriptions of "p[subscript rep]" that start with a frequentist account of confidence intervals, draw on R. A. Fisher's fiducial argument, and do not make Bayesian assumptions. Links are described among "p[subscript rep]," "p" values, and the probability a confidence interval will capture…

In Robbins, R. & McKone, E. (2006). No face-like processing for object-of-expertise in three behavioural tasks. "Cognition" this issue, we showed face-like holistic/configural processing does not occur for objects-of-expertise on standard paradigms including inversion, part-whole, part-in-configurally-transformed-whole, and the standard composite…

On the basis of a review of the literature and the results of three experiments with dog experts, Robbins and McKone [Robbins, R. A., & McKone, E. (2006). No face-like processing for objects-of-expertise in three behavioural tasks, "Cognition"] argue that there is little or no evidence supporting an expertise account of the differences in…

Contrary to the deterministic nature of the adipocyte- number hypothesis, correlations between adiposity data recorded during infancy and data recorded during the school- age period or later are very low. There is no convincing evidence the obese infant has more than a slight tendency to become an obese adult. (Author/MP)

For years, researchers have debated the misinterpretation of the null hypothesis significance test (NHST). Many researchers overemphasize the results of the NHST and underemphasize or even omit effect size measures. This paper addresses the common mistaken perceptions regarding the NHST. Several common effect size estimates are discussed. A small…

Author responds to critique by Daniel Griffiths (Educational Administration Quarterly v. 19, p. 201-21) by defending his work in three areas: derivation of hypotheses, testing of hypotheses, and erroneous attribution of assumptions. (JW)

This paper provides a rationale for using and sustaining rival hypotheses Web-based tools to promote students' understanding of the concepts of internal and external validity. Five major concerns are identified. The first is that, in their present form, the Web sites subsume the discussion of threats to validity under experimental designs, giving…

This paper provides examples of how one can use the research issue and the relationships between qualitative and quantitative research as a frame for instructing students and judging the quality of research. The emphasis is on validity estimates, also called legitimization techniques, with attention to the idea of a qualitative-quantitative…

The hypothetical deduction model of educational research should be replaced by one that distinguishes between the logical structure of hypothetico-deduction and its methodological application. Such a framework explores relationships between three levels of explanation: observation sentences, observation categoricals, and theory formulations. (SK)

Argues that reliance upon verification procedures has inhibited theory building in communication. Advances four falsification procedures and presents examples from communication studies. Offers several implications these procedures have for empirical research in communication. (PD)

Age-related changes in representational flexibility are a characteristic feature of declarative memory development. The authors suggest that a qualitative shift in the nature of infants' memory representations accounts for increasing memory flexibility with age. We will argue that a comprehensive theory of declarative memory development must (1)…

Piaget's last two works may add a new level of coherence and generality to his theories, which are grounded in an insight about the interdependence of reality and knowledge about reality. Piaget expanded Kant's epistemology to encompass three systems operating in the frames of biology, psychology, and culture. (MDM)
