The central roles of science in the field of remedial and special education are to (a) identify basic laws of nature and (b) apply those laws in the design of practices that achieve socially valued outcomes. The scientific process is designed to allow demonstration of specific (typically positive) outcomes, and to assist in the attribution of…

There is currently a considerable diversity of quantitative measures available for summarizing the results in single-case studies. Given that the interpretation of some of them is difficult due to the lack of established benchmarks, the current article proposes an approach for obtaining further numerical evidence on the importance of the results,…

Maxwell and Cole (2007) showed that cross-sectional approaches to mediation typically generate substantially biased estimates of longitudinal parameters in the special case of complete mediation. However, their results did not apply to the more typical case of partial mediation. We extend their previous work by showing that substantial bias can…

The basic assumption behind psychoanalytic psychotherapy is that mental contents that were once warded off come to emerge in the course of a successful treatment. This paper focuses on specific contents which a patient became aware of during a psychoanalytic treatment. (Editor)

This paper identifies typical sampling problems, including improper application of the Central Limit Theorem, that are associated with the probability-based sampling procedures currently used in clinical psychology research. It then presents two alternative research designs, the theory validation model and the extended case study model, which…

That researchers should give anonymity to research sites and to the individuals involved in research is usually taken as an ethical norm. Such a norm is embodied internationally in most of the ethical guidelines and codes of practice of the various educational, sociological and psychological research associations and societies. This paper…

This article presents a case study where students examine an advertisement claiming that listening to classical music in an advertised CD set will enhance their cognitive skills and creativity. Students evaluate the claims and evidence cited to support them and then determine how they might independently verify the claims. The author states that…

Conveying information to clients has a variety of purposes in professional-client interactions. It has a clear relationship to client access to participation in the decisions made about a presenting problem. Speech-language pathologists tend to assume they do this competently and to the advantage of their clients, but rarely has this assumption…

In seven articles methods of enhancing clinical practice through empirical approaches and realistic approaches and realistic research are discussed including: (1) Cronbach's method of intensive observation; (2) intensive monitoring of treatment strength, integrity, and effectiveness; (3) the use of dependent measures; (4) drawing valid conclusions…
