Perceptual comparisons of adolescent stutterers' and nonstutterers' fluent speech

Numerous investigators have reported that listeners are able to perceptually differentiate adult stutterers' and nonstutterers' fluent speech productions. However, findings from similar studies with children ranging in age from 3 to 9 yr have indicated that perceptual discrimination of child stutterers is difficult. A logical extension of this line of investigation would be to determine when during maturation from childhood to adulthood stutterers' fluent speech becomes perceptibly different than nonstutterers'. Therefore, in this study similar fluent speech samples from seven 12–16-yr-old adolescent male stutterers and seven matched nonstutterers were analyzed perceptually in a paired stimulus paradigm by 15 sophisticated listeners. Individual subject analyses using signal detection theory revealed that five of the seven stutterers were discriminated. When averaged for subject group comparison, these findings indicated that listeners successfully discriminated between the fluent speech of the two groups. Therefore, the perceptual difference in fluent speech production reported previously for adults appears to be present by adolescence.     

The topography of aggressive behavior of an attacking rat is determined by the behavior of the victim

Untreated rats were observed to either bite or box with Pentobarbital-treated opponents in a shockelicited aggression situation. Specific behaviors such as ataxia movements and submissive postures immediately preceded biting attacks, but rarely boxing whereas behaviors such as moving around the chamber and upright threat postures immediately preceded boxing attacks, but rarely biting. These data suggest that the topography of aggressive behavior of an attacking rat is determined by the behavior of the victim.     

The institutionalization of sociological paradigms: Three examples from early French sociology

Utilizing a model of sociological paradigms which encompasses the cogency of sociological theories, their congruence with their cultural milieu and their reinforcement through institutionalization, this paper examines three interpretations of sociology which competed for recognition in France at the end of the nineteenth century. René Worms created institutions for the new field of new field of sociology, but did not possess a viable sociological theory with which to make these institutions effective in advancing the discipline. Gabriel Tarde possessed a sociological theory and opportunities to institutionalize it, but failed to do so because of a pre-modern attitude toward science. Only Emile Durkheim was able to successfully institutionalize his conception of sociology through his teaching career and his journal, L'Année sociologique.
