The four faces of omission

In this paper, the ontological, terminological, epistemological, and ethical aspects of omission are considered in a coherent and balanced framework, based on the idea that there are omissions which are actions and omissions which are non-actions. In particular, we suggest that the approach to causation which best deals with omission is Mackie's INUS conditional proposal. We argue that omissions are determined partly by the ontological conditional structure of reality, and partly by the interests, beliefs, and values of observers. The final upshot is that moral judgments involved in cases of omissions cannot be grounded on, but are the ground for judgments about what INUS conditions count as omissions.     

The four free-operant freedoms

This article reviews early free-operant conditioning laboratory research and applications. The seldom-mentioned four free-operant freedoms are described for the first time in detail. Most current behavior analysts do not realize that the freedom to form responses and the freedom to speed responses were crucial steps in designing free-operant operanda in the 1950s. These four freedoms were known by the laboratory researchers of the 1950s to the point that, along with operanda design, Sidman (1960) did not feel the need to detail them in his classic, Tactics of Scientific Research. The dimensions of freedom in the operant were so well understood and accepted in the 1950s that most thought it redundant to use the term free operant. These issues are reviewed in some detail for younger behavior analysts who did not have the opportunity of learning them firsthand.     

Concurrent validity of four androgyny instruments

Four sex-role instruments were administered to a group of 281 graduate and undergraduate students at an urban university. Concurrent validity was examined through the use of correlational and factor-analytic techniques. Seven problems in interpretation of the categorizations made by the several instruments were identified: (1) item homogeneity of individual scales; (2) convergence of corresponding scales and divergence of scales from their complements; (3) multifactoriality; (4) factor complexity; (5) distribution of content across instruments; (6) interaction between factor complexity and content balance; and (7) correspondence of classifications of subjects across instruments.     

An editorial in four parts

In writing this editorial, I have four objectives: (1) to make statement concerning EJWOP’s mission—in particular, why does the world need a European Journal of Work and Organizational Psychology; (2) to review the state of our scientific practice and how EJWOP can help contribute to that practice; (3) to make a statement on the kind of papers EJWOP will strive to publish; and (4) to say thanks to the out-going editor and associate editors.     

Crossed aphasia: analysis of four cases

Data from the Rehabilitation Institute of Chicago was used to contrast a sample of 358 aphasics with data from a Boston aphasia and aging study (L. Obler, M. Albert, H. Goodglass, and F. Benson, Brain and Language, 6, 318–322, 1978). Unlike the females, Chicago males showed remarkable similarity to the Boston male sample for the Broca, Wernicke, and Global groups with ratios of approximately four Broca's to every two Wernicke's and Global aphasics. Similar to the Boston Sample, Wernicke's aphasics were 11.6 years older (p < .001) than Broca's aphasics.
