What do decision models tell us about information use?

This paper develops hypotheses about the implications of different types of decision for the utilization of different types of systematically produced information: data, research, and analysis. The engineering and enlightenment models found in the knowledge utilization literature prove inadequate for this purpose. We turn to three decision models—routine, incremental, and fundamental–and determine their implied demands for information. We also examine how information might be used in scanning procedures in anticipation of decision regime shifts. The results suggest that patterns of information should differ markedly in each decision context and indicate that there may be an inherent bias against the use of research in decision. Evert A. Lindquist, a doctoral candidate at the Graduate School of Public Policy, University of Calfornia at Berkeley, is completing a dissertation onPolicy Institutes in Canada: The Organization and Relevance of Public Inquiry and will join the faculty of the Department of Political Science at the University of Toronto this fall. Organizations, public policy, and the role of information in decision making are among his primary research interests.     

On neurotransmitter mechanisms of reinforcement and internal inhibition

Experiments reported in this study have been performed in order to investigate cholinergic and GABA-ergic neurotransmitter systems and substance P in the realization of internal inhibition and pain reinforcement. This was accomplished during the elaboration of inhibitory and defensive conditioned reflexes to light flashes in alert, nonimmobilized rabbits. Present results together with a review of past research indicate that the cholinergic system is directly involved in transmitting the effects of pain reinforcement to neocortical neurons. Substance P, a neuropeptide, reduces the background activity of neocortical and hippocampol neurons and the response of cortical neurons to pain and positive conditioned stimuli. The cholinergic system and substance P exert a modulating effect on the elaboration of internal inhibition. Phenybut, a GABA derivative capable of penetrating the blood-brain barrier, enhances inhibitory hyperpolarization in the cerebral cortex and improves discrimination between the inhibitory and reinforcing light flashes. It appears, therefore, that the GABA-ergic system plays a leading part in the elaboration of internal inhibition. Neuronal activity and slow potential changes in response to positive conditioned and pain stimuli occur in the same direction after administering the preparations, and the dynamics of these changes is different from that in responses to inhibitory stimuli. It may be supposed on these grounds that the neurotransmitter and neuromodulator systems studied possess a considerable degree of plasticity.     

Nodality effects during equivalence class formation: An extension to sight-word reading and concept development

Three students with moderate disabilities were taught to read and match-to-sample sight words comprising stimulus sets based upon the four food groups. We taught students conditional discriminations within four four-member sets using a single-sample/four-comparison procedure. Students were taught A-B, B-C, and C-D conditional discriminations for each of the four potential stimulus classes. Subsequent probes tested for relations based upon symmetry and one-node and two-node transitivity. The performances for all students indicated that symmetric relations emerged before one-node transitive relations, and that one-node transitive relations emerged before two-node transitive relations. These results are consistent with a pattern of responding, referred to as a "nodality effect," in which relations with fewer nodes are demonstrated prior to the demonstration of relations with a greater number of nodes. These results extend this area of research to sight-word reading for students with moderate disabilities.     

Comparing interspersed requests and social comments as antecedents for increasing student compliance

Two students were alternately presented with interspersed high-compliance requests and social comments as antecedents to low-compliance requests. An initial comparison demonstrated similar positive effects on compliance for interspersed requests and social comments. A second analysis indicated that the effectiveness of social comments for increasing compliance was related to the time interval between social comments and low-compliance requests.     

The neurophysiological validation of the hyperpolarization theory of internal inhibition

The experiments in conscious non-immobilized rabbits showed that cessation of the reactions without reinforcement (elaboration of the internal inhibition) is accompanied by an enhanced phasic state, by alternation of activation and inhibition of neuron firing, and by the corresponding slow potential oscillation (SPO). These changes can be either localized, predominantly in the structures of conditioned stimulus, or, under enhancement of the inhibitory state, generalized in the brain structures. On the basis of our experience and published data, it is concluded that the above event results from relative enhancement of the inhibitory hyperpolarizing processes due to increase in reactivity of the inhibitory systems to stimulus, which acquires inhibitory properties during learning. Changes in the excitability and reactivity of neuron populations appearing during enhancement of the hyperpolarizing inhibition, and differing in the various brain structures, play an active role in the execution of the main function of the internal inhibition: limitation of excitation transmission to the effectors. An inhibitory mediator gamma aminobutyric acid (GABA) is of great importance in inhibiting the excitation in response to the stimulus which lost its biological significance. These experimental data and their interpretation in the light of published data give the basis for the development of the hyperpolarization theory of internal inhibition.     

Development and validation of a measure of display rule knowledge: the display rule assessment inventory

As one component of emotion regulation, display rules, which reflect the regulation of expressive behavior, have been the topic of many studies. Despite their theoretical and empirical importance, however, to date there is no measure of display rules that assesses a full range of behavioral responses that are theoretically possible when emotion is elicited. This article reports the development of a new measure of display rules that surveys 5 expressive modes: expression, deamplification, amplification, qualification, and masking. Two studies provide evidence for its internal and temporal reliability and for its content, convergent, discriminant, external, and concurrent predictive validity. Additionally, Study 1, involving American, Russian, and Japanese participants, demonstrated predictable cultural differences on each of the expressive modes.     

Wilhelm Reich in Soviet Russia: Psychoanalysis,Marxism, and the Stalinist reaction

Abstract

In 1929, Wilhelm Reich lectured on “Psychoanalysis as a natural science” before the Communist Academy in Moscow; he was the only Freudian-trained Central European psychoanalyst to do so. That same year, his article “Dialectical materialism and psychoanalysis” was published in the Academy's journal, Under the Banner of Marxism, in both Moscow and Berlin. By this time, Reich's involvement with political activism aligned with the Austrian Communist Party was increasing, while simultaneously psychoanalysis in the Soviet Union was in decline. Our paper places these events in their proper historical context and includes a discussion of the various attempts to determine the compatibility of psychoanalysis and Marxism. We offer analyses of both the article, “Dialectical materialism and psychoanalysis,” and the lecture, “Psychoanalysis as a natural science,” and the reactions to both by Reich's Russian critics. We show the ways in which responses to his lecture foreshadow what becomes the standard Soviet assessment of psychoanalysis. As an appendix to this paper, we provide the first English translation of the Russian account of his lecture, as published in the Herald of the Communist Academy.     

Language and the perception of emotion

Three studies assessed the relationship between language and the perception of emotion. The authors predicted and found that the accessibility of emotion words influenced participants' speed or accuracy in perceiving facial behaviors depicting emotion. Specifically, emotion words were either primed or temporarily made less accessible using a semantic satiation procedure. In Studies 1 and 2, participants were slower to categorize facial behaviors depicting emotion (i.e., a face depicting anger) after an emotion word (e.g., "anger") was satiated. In Study 3, participants were less accurate to categorize facial behaviors depicting emotion after an emotion word was satiated. The implications of these findings for a linguistically relative view of emotion perception are discussed.     

Russia's Umma and its Muftis

Abstract

In December 2006, after years of debate, the Romanian parliament passed the country's first postcommunist law on religious freedom and the status of religious denominations. This article offers a detailed examination of the law's provisions, describes the context in which the norm was adopted, discusses the legal framework before the law's passage, and provides a short analysis of the law's reception in Romania.     

Healers,Leaders and Entrepreneurs: Shamanic Revival in Southern Siberia

While it is generally agreed that in the postmodern world all tradition is invented, in many post-colonial contexts the emerging identities are spelled out in the idiom of ‘traditional heritage’. This article considers the social field of ‘shamanism’ as it has been shaped in the post-Soviet years in Tuva, an autonomous republic within the Russian Federation in Southern Siberia, and analyses Tuvan shamanism as a product of local historical and social forces, and global processes. Based on both the ethnography of the organisational structure of contemporary Tuvan shamanism, and portraits of different categories of practitioners, the article analyses continuity and change in various aspects of what is locally seen as ‘traditional knowledge’, and discusses different skills, orientations, and divisions of labour among the practitioners. Shamanism in post-Soviet Siberia is seen as a postmodern religious movement enmeshed in global structures and processes, and it is only in this context that a local tradition can become alive and meaningful again.
