The demand for clinical accountability and the documentation of therapeutic effectiveness continues to increase in health-related settings. Therapists are attempting to address this increasing demand by adapting methods based on traditional experimental models of research to evaluate their clinical practice. Experimental and quasi-experimental designs, however, are often limited usefulness in c...

This Perspectives is devoted to the ideas of the French zoologist Georges Teissier about the mechanisms of evolution and the relations between micro- and macroevolution. Working in an almost universally neo-Lamarckian context in France, Teissier was one of the very few Darwinians there at the time of the evolutionary synthesis. The general atmosphere of French zoology during the 1920s and the 1...

Over the past 20 years, human contingency learning has resurfaced as an important topic within experimental psychology. This renewed interest was sparked mainly by the proposal that associative models of Pavlovian conditioning might also apply to human contingency learning--a proposal that has led to many new empirical findings and theoretical developments. We provide a brief review of these re...

However, a warning by Babbie should be emphasized: It may be that "the indicators of humane patient care used in these analyses are not adequate to the research problem." Inferences about faculty performance based on faculty views reported by and often ...

Alternating Treatments Designs (ATD) with random assignment of the treatments to the measurement times provide very powerful single-case experiments. However, complete randomization might cause too many consecutive administrations of the same treatment to occur in the design. In order to exclude these possibilities, an ATD with restricted randomization can be used. In this article we provide a ...
