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.     

Neuroticism,BIS, and reactivity to discrete negative mood inductions

Research has established relationships between the personality dimensions of neuroticism and BIS and broad negative emotional reactivity. However, few researchers have examined the relationships among neuroticism, BIS, and discrete negative emotional reactivities. The present study examined whether individuals scoring high on neuroticism and BIS were more reactive across four discrete negative mood inductions, relative to those scoring low on these traits. Participants (n = 166) completed personality questionnaires, measures of current mood, viewed a specific mood-inducing film clip (sadness, anger, fear or disgust) and then reported their moods a second time. Results revealed that neuroticism/BIS was associated with high reactivity to the fear and sadness inductions. Neuroticism/BIS did not predict anger or disgust reactivity, but neuroticism/BIS and extraversion/BAS interacted in predicting anger. Although further research is needed to extend generalizability, it appears that neuroticism and BIS predict negative emotional reactivity broadly, but not ubiquitously.     

Clinical features of major depressive disorder in adolescents and their relatives: impact on familial aggregation, implications for phenotype definition, and specificity of transmission

Three questions were addressed using family study data from a community sample: (a) Which clinical features of major depressive disorder (MDD) in adolescents are associated with elevated rates of MDD in relatives? (b) Which features of MDD in relatives distinguish family members of depressed adolescents from relatives of adolescents without mood disorders (NMD)? and (c) Do depressed adolescents with particular features have higher proportions of depressed relatives with the same features? Participants included 268 MDD adolescents, 401 NMD adolescents, and their 2,202 first-degree relatives. Rates of MDD were highest among relatives of depressed adolescents with recurrent episodes and greater impairment. Depression severity best distinguished the relatives of depressed adolescents from relatives of controls. Specific clinical features did not aggregate in families.     

Pancultural Gender Stereotypes Revisited: The Five Factor Model

Williams and Best's (1982, 1990a) cross-culturalgender stereotype data from 25 countries, previouslyanalyzed in terms of affective meanings, ego states, andpsychological needs, were re-analyzed in terms of the Five Factor Model (FFM) of personality.In each country, participants were approximately 100university students, equally divided by gender. Withresults averaged across all countries, it was found that the pancultural male stereotype was higherthan the pancultural female stereotype on Extraversion,Conscientiousness, Emotional Stability, and Openness toExperience while the pancultural female stereotype was higher on Agreeableness. Re-analysis of thestereotype data from Japan and Pakistan, which had beenfound relatively atypical in previous analyses, revealedFFM profiles generally similar to the pancultural profiles. The evaluative nature of each factoris discussed and related to the stereotypes associalization models.     

El lugar de la interferencia en la percepción de estímulos simultáneos

RESUMEN

En una amplia variedad de tareas de detección de objetivos auditivos y visuales, la ejecución era escasamente influida por el número de no-objetivos simultáneos, pero le afectaba si los objetivos simultáneos debían ser detectados por separado. Se ha sugerido que sólo los objetivos necesitan pasar por un sistema de capacidad limitada que conduce a la conciencia; los no-objetivos pueden ser identificados y rechazados por un procesamiento paralelo e inconsciente. Puesto que las palabras no- objetivo, por ejemplo, se pueden rechazar en base al significado, el estímulo debe ser completamente analizado antes de pasar por el sistema de capacidad limitada. De modo general, la disminución en la ejecución debida a la atención dividida es acusada siempre que la estimulación simultánea (psicofísica, verbal, etc.) se deba identificar por separado, puesto que bajo estas circunstancias cualquier estimulación debe pasar por un sistema de capacidad limitada hasta la conciencia.     

Teaching peer reinforcement and grocery words: An investigation of observational learning and instructive feedback

A multiple probe across behaviors design, replicated across participants, assessed the effectiveness of constant time delay in teaching appropriate peer reinforcement and grocery words to 3 elementary students with moderate intellectual disabilities. Additionally, pretests and posttests assessed the acquisition of the participants' observational learning (acquisition of peers' grocery words) and instructive feedback (related information supplied by the teacher in the consequent event). Results indicate that the participants learned (a) how to appropriately reinforce peers, (b) to read their grocery words, (c) some of the targeted stimuli of their peers, and (d) much of the instructive feedback that was associated with each of the grocery words. Maintenance data indicate that the participants maintained their target grocery words at high levels of accuracy.     

Event detail and confidence in gambling: The role of counterfactual thought reactions

Differences in people’s reactions to the same events described with full vs. sketchy information are examined. It is hypothesized that differences in counterfactual thought reactions to varying levels of event detail shape confidence in, and willingness to gamble on similar, future events. In three experiments, participants were presented with different types and levels of event detail about their performances on a trivia test, on several games of blackjack, or on gambling on a professional horse race. Upward counterfactual thoughts were observed more frequently in response to losing events containing high levels of detail and specificity. Importantly, counterfactual thought frequency also mediated the relationships between event detail and the level of confidence in and willingness to gamble on similar, future events. Evidence also indicates that this relationship is based on the hindsight bias that results from counterfactual thinking. Results are discussed in terms of cognitive processes and decision making research.
