Work‐place bullying: A group processes framework

Work‐place bullying is primarily conceptualized in the literature from an individual or interpersonal perspective with a focus on the victim. The impact of the broader organizational context on bullying has also been considered to a lesser extent. Only a small amount of research exists, however, regarding the group‐level processes that impact on the incidence and maintenance of bullying behaviour. We adopt a group level perspective to theoretically discuss and explain the processes involved in the occurrence and maintenance of work‐place bullying behaviours. Using Social Identity Theory ( Tajfel & Turner, 1986 ) and Social Rules Theory ( Argyle, Henderson, & Furnham, 1985 ), two conceptual frameworks are presented that consider work‐place bullying at the intra‐group and inter‐group levels. Several propositions are put forward regarding the likelihood of bullying in work groups. Suggested directions for empirical research are addressed and practical implications are also discussed.     

Statistical inference in behavior analysis: Some things significance testing does and does not do

Significance testing plays a prominent role in behavioral science, but its value is frequently overestimated. It does not estimate the reliability of a finding, it does not yield a probability that results are due to chance, nor does it usually answer an important question. In behavioral science it can limit the reasons for doing experiments, reduce scientific responsibility, and emphasize population parameters at the expense of behavior. It can, and usually does, lead to a poor approach to theory testing, and it can also, in behavior-analytic experiments, discount reliability of data. At best, statistical significance is an ancillary aspect of a set of data, and therefore should play a relatively minor role in advancing a science of behavior.     

Rate dependency, behavioral mechanisms, and behavioral pharmacology.

Behavioral pharmacology has become increasingly independent of the experimental analysis of behavior. At its beginning, behavioral pharmacology was closely related to the experimental analysis of behavior, with developments in each field aiding the other. Early attempts to systematize data in behavioral pharmacology culminated with the development of the rate-dependency concept, but as this principle was found to have more limited generality than originally was hoped, a theoretical void developed. This circumstance was followed by increased reliance on pharmacological theory as a basis for experimentation and interpretation, with an attendant decrease in emphasis on environmental variables and behavioral interpretations. Lack of interplay between behavioral pharmacology and the experimental analysis of behavior is detrimental to both disciplines because each could contribute significantly to the other. The current trend might be reversed if more research were directed at elucidating behavioral mechanisms of drug action.     

The role of sensory-motor information in object recognition: evidence from category-specific visual agnosia

The role of sensory-motor representations in object recognition was investigated in experiments involving AD, a patient with mild visual agnosia who was impaired in the recognition of visually presented living as compared to non-living entities. AD named visually presented items for which sensory-motor information was available significantly more reliably than items for which such information was not available; this was true when all items were non-living. Naming of objects from their associated sound was normal. These data suggest that both information about object form computed in the ventral visual system as well as sensory-motor information specifying the manner of manipulation contribute to object recognition.
