Boltzmann and Epistemology

Synthese - This paper is an attempt to clarify why Ludwig Boltzmann from about 1895 to 1905 seemed to adopt a series of extreme epistemological positions, ranging from phenomenalism to pragmatism,...

Indigenous Psychologies: The Meaning of the Concept and its Assessment: Introduction

La signification des concepts de psychologie indigoène et d'indigoénisation, les processus par lesquels ils se réalisent, est exploré dans les quatres premiers articles de ce numéro spécial. Les concepts sont examinés tout d' abord à partir des perspectives plus larges de la psychologie sociale des sciences (Adair) et la psychologie interculturelle (Poortinga), ainsi que dans deux applications concrètes des approches de psychologie indignée au Mexique (Díaz-Loving) et en Corée (Kim, Park, et Park). Dans la seconde partie, trois articles rendent compte des recherches empiriques évaluant l'ampleur du développement indignée en Turquie, ex-URSS, au Venezuela, et Porto-Rico. Cette introduction au numéro spécial résume quelques uns des points communs et des différences dans les contributions.
The meaning of the concepts of indigenous psychologies and of indigenisation, the process by which they are achieved, are explored within the first four articles of this special issue. The concepts are examined initially in the abstract from the broader perspectives of the social psychology of science (Adair) and cross-cultural psychology (Poortinga), and in two concrete applications of indigenous psychology approaches in Mexico (Díaz-Loving) and Korea (Kim, Park, & Park). In the second part of this special issue, three articles report on empirical research assessing the extent of indigenous development that has occurred in Turkey, the former USSR, Venezuela, and Puerto Rico. This introduction summarises some of the commonalities and differences among the contributions.     

COMPETITION BETWEEN POSITIVE AND NEGATIVE REINFORCEMENT IN THE TREATMENT OF ESCAPE BEHAVIOR

We compared the effects of reinforcing compliance with either positive reinforcement (edible items) or negative reinforcement (a break) on 5 participants' escape-maintained problem behavior. Both procedures were assessed with or without extinction. Results showed that compliance was higher and problem behavior was lower for all participants when compliance produced an edible item rather than a break. Treatment gains were achieved without the use of extinction. Results are discussed regarding the use of positive reinforcement to treat escape behavior.
