IV. Logic and truth‐finding in society and sociology

The question of sociological truth‐finding is posed in the light of the view that logical formalizations, along with other arguments, only acquire relevance in illocutionary contexts, where it is not so much the abstract correctness of a sentence as the stating of it that counts. In order to become a counterfactual an argument requires its antecedent to be recognized as being contrary to the ‘facts’. To this extent there is a clear link with ‘reality’ or with a view of the world that is taken as factually given. Social science develops on the basis not only of generalizations but also of historical facts and political requirements. The question arises: in terms of what world‐view or purpose can we unambiguously declare a conditional to be a counterfactual ‐ and a significant or non‐trivial one at that? Further, can Elster's clarifications help identify political agents and the proper entities within and through which political action is performed? Finally, the problem‐solving capacity of the concept of closeness of one possible world to another or to the actual world, especially with regard to counterfactuals and causality, is questioned.     

Psychoanalysis and Politics by R. E. Money-Kyrle

Abstract

Group psychotherapists in their everyday practice confront a series of ethical problems, some of which rise to the level of ethical dilemmas. This two-part special series will address how the group psychotherapist can address these problems and dilemmas in a way that leads to an ethical course of conduct. This article introduces the series by examining ethical principles and decision-making processes that are relevant to the wide range of issues that confront the group psychotherapist. The article also considers the person of the group psychotherapist him or herself and notes that certain personal qualities might create a foundation for ethical thinking and behavior.     

Changes in Skin Potentials During the Psychogalvanic Reflex

Researchers have shown that working memory is related to a variety of high-level cognitive processes. However, the results of recent research have suggested that may be because of its role in attentional control. In the present experiment, the authors investigated that hypothesis by using an attentional interference task with musical stimuli. Listeners were asked to monitor one ear for either a clarinet or violin tone and to ignore any information in the other ear. On some of the trials, they heard only one tone and on other trials, either the same instrument in both ears or different instruments. Individual differences were measured in working memory and musical experience. The results showed more attentional interference in the different-instrument condition for participants with lower working memory scores, which suggested that working memory involves the ability to control attention to inhibit irrelevant information.     

Coordination of Grip Configurations as a Function of Force Output

In this investigation, the authors examined the coordination and control of force production by the digits of the hand as a function of criterion force level and grip configuration. Each adult participant (N = 6: 3 men and 3 women) was required to place the thumb and a finger (or fingers) upon load cells that were fixed to a grasping apparatus that was clamped to a table. In the task, participants had to match a criterion continuous constant total force level displayed on a computer screen. There were 10 trials at each grip configuration and criterion force level combination on each of 3 consecutive days. The results showed that (a) different grip configurations minimized error at each force level; (b) there was a specific digit pairing within a given grip configuration that produced the highest correlation of force output; (c) the correlation between the force output of digits generally increased at higher force levels; (d) error was reduced at each force level and grip configuration over the practice period; and (e) the organization of the force output of each digit varied as a function of digit, force level, grip configuration, and practice. The findings are consistent with the hypothesis that coordination of the digits in prehension is reflective of an adaptive, task-specific solution that is modified with practice.     

A Developmental Analysis of Performance Ratings

In this study, we examined the performance appraisal process from a developmental perspective. Components of cognitive structure, measured in terms of differentiation and hierarchic integration, were obtained from 45 American students representing three different academic levels at three times during a 15-week semester. These students' performance evaluations (ratings) of their psychology instructors were collected during the first and final sessions. The results indicated that although both differentiation and hierarchic integration seemed to change systematically, even over a short period of time, there was no corresponding change in the halo inherent in the raters' ratings. We present possible explanations for the failure of developmental changes in cognitive structure to be reflected in the halo inherent in the performance ratings, as would be predicted by Schneier's (1977) cognitive compatibility hypothesis. Increased emphasis on developmental aspects of the performance appraisal process is recommended.     

Invited Essay: A New System Of Politics: Government,Governance, And Political Decision Making In The Twenty-First Century

The present system of politics is based on the centrality of economics. This system is not capable of coming to grips with the problems confronting humanity. A culture-based system of politics is required to do this and prevent ecological disaster. This system would make it possible to reduce the demands human beings are making on the natural environment and situate human welfare, environmental well-being, and the public interest at the core of the political process. The risks of such a system could be reduced through cultural education and improved cultural understanding.     

Speech Intelligibility and Recall of Spoken Material Heard at Different Signal‐to‐noise Ratios and the Role Played by Working Memory Capacity

We studied speech intelligibility and memory performance for speech material heard under different signal‐to‐noise (S/N) ratios. Pre‐experimental measures of working memory capacity (WMC) were taken to explore individual susceptibility to the disruptive effects of noise. Thirty‐five participants first completed a WMC‐operation span task in quiet and later listened to spoken word lists containing 11 one‐syllable phonetically balanced words presented at four different S/N ratios (+12, +9, +6, and +3). Participants repeated each word aloud immediately after its presentation, to establish speech intelligibility and later on performed a free recall task for those words. The speech intelligibility function decreased linearly with increasing S/N levels for both the high‐WMC and low‐WMC groups. However, only the low‐WMC group had decreasing memory performance with increasing S/N levels. The memory of the high‐WMC individuals was not affected by increased S/N levels. Our results suggest that individual differences in WMC counteract some of the negative effects of speech noise. Copyright © 2012 John Wiley & Sons, Ltd.
