Timing at the Start of Associative Learning

Some theories of associative learning imply that time plays a fundamental role in the acquisition process. Consistent with these theories, this paper presents evidence that the time from the onset of a conditioned stimulus (CS) until presentation of the unconditioned stimulus (US) is learned very rapidly at the start of training. We report two autoshaping studies and a study on aversive conditioning in goldfish in which we examine timing at the start of conditioning. We also review data from a number of other conditioning preparations, including fear-potentiated startle, appetitive conditioning in rats, and eyeblink conditioning in rabbits, that report conditioned response (CR) timing early in training. Acquisition speed and the very first expressions of conditioned responding often show sensitivity to the time of US presentation. In instances where temporal control is slowly expressed, it is likely due to performance factors, not to slow learning about time. In fact, the learning about time may be a necessary condition for associative learning.     

The Personal and Social Correlates of Spiritual Well-Being Among Primary School Teachers

A sample of 311 primary school teachers completed the Spiritual Health in Four Domains Index alongside the abbreviated revised Eysenck Personality Questionnaire and measures of religiosity. The data demonstrate that higher levels of spiritual health are found among older teachers who record low scores on the psychoticism scale and who practice religious faith through church attendance and personal prayer.     

Who's Afraid of Undermining?

The Principal Principle (PP) says that,for any proposition A, given any admissible evidenceand the proposition that the chance of A is x%,one's conditional credence in A should be x%. HumeanSupervenience (HS) claims that, among possible worldslike ours, no two differ without differing inthe spacetime-point-by-spacetime-point arrangement oflocal properties. David Lewis (1986b, 1994a)has argued that PP contradicts HS, and thevalidity of his argument has been endorsed byBigelow et al. (1993),Thau (1994),Hall (1994),Strevens (1995),Ismael (1996),Hoefer (1997), and Black (1998).Against this consensus, I argue thatPP might not contradict HS: Lewis'sargument is invalid, and every attempt – withina broad class of attempts – toamend the argument fails.     

Success and Gender: Determining the Rate of Advancement for Intercollegiate Athletic Directors

Since the demise of the Association for Intercollegiate Athletics for Women (AIAW), female sport administrators have continued their struggle to reestablish their place as athletic directors. The purpose of this study was to assess the rate of advancement (success ratio) of intercollegiate athletic directors, with a primary focus on gender. Athletic directors from 157 NCAA (National Collegiate Athletics Association) member institutions participated in the study. The preliminary results confirmed the expected findings that hegemonic masculinity was entrenched within intercollegiate athletics. The success ratio of male athletic directors differed from that of female athletic directors, and the difference was significant (p ≤ .05). The success ratio for men was higher than the ratio for women. Further analyses, however, showed that female athletic directors had higher success ratios than their male peers at lower level institutions. Although parity in numbers has not yet been achieved across the NCAA, the glass ceiling at Division I institutions may begin to crack as more women achieve success at the lower level institutions.     

Causal judgement from contingency information: Judging interactions between two causal candidates

In two experiments participants judged the extent to which occurrences and non-occurrences of an effect could be attributed to an interaction between two causal candidates A and B. In Experiment 1 judgements were influenced by the proportion of instances normatively evaluated as confirmatory for the interaction interpretation, when the objective contingency was held constant. Information about instances in which both candidates were present and the effect occurred was more influential than information about instances in which both candidates were absent and the effect did not occur. In Experiment 2 the occurrence rate of the effect when both candidates were present, when A alone was present, when B alone was present, and when both were absent was manipulated. Interaction judgements were mainly determined by occurrence rate when both were present. There was also a significant effect of occurrence rate when both were absent, but the other two occurrence rates had no significant effect. These results are interpreted as supporting a general model in which causal judgements are made according to the proportion of instances evaluated as supporting the interpretation being judged.     

Hertz and Wittgenstein's Philosophy of Science

The German physicist Heinrich Hertz played a decisive role for Wittgenstein's use of a unique philosophical method. Wittgenstein applied this method successfully to critical problems in logic and mathematics throughout his life. Logical paradoxes and foundational problems including those of mathematics were seen as pseudo-problems requiring clarity instead of solution. In effect, Wittgenstein's controversial response to David Hilbert and Kurt Gödel was deeply influenced by Hertz and can only be fully understood when seen in this context. To comprehend the arguments against the metamathematical programme, and to appreciate how profoundly the philosophical method employed actually shaped the content of Wittgenstein's philosophy, it is necessary to make an intellectual biographical reconstruction of their philosophical framework, tracing the Hertzian elements in the early as well as in the later writings. In order to write Wittgenstein's biography, we have to take seriously the coherence of his thought throughout his life, and not let convenient philosophical ideologies be our guidance in drawing up a “Wittgensteinian philosophy”. To do so, we have to take a second look upon what he actually wrote, not only in the already published material, but in the entire Nachlass. Clearly, this is not easily done, but it is a necessary task in the historical reconstruction of Wittgenstein's life and work.     

The Diverse Voices of Political Islam in Post-Suharto Indonesia

Since the resignation of Suharto as president of Indonesia in May 1998, the country has suffered from chronic instability on various fronts. Economic disruption resulting from the Asian economic crisis of 1997 continues. Food shortages have been widespread throughout the archipelago. Social instability has been rife, especially in densely populated areas where communities have had to compete for scarce resources. Inter-religious conflict has exploded, especially between Muslim and Christian communities, reflecting a common outcome of economic and social instability. This paper will focus upon Indonesia in the period May 1998-July 2001 and will draw upon wide-ranging print and electronic media reports as well as secondary scholarship. Particular attention will be devoted to the political stage and to the changing role of Islam in that context. We will consider the different voices being heard among the Muslim community, the key issues of debate that have preoccupied Muslim political leaders and the ingredients which have contributed to a surge in Muslim-Christian conflict in Indonesia during the period being examined.     

Cross-fertilization versus transmission: Recommendations for developing a bidirectional approach to psychotherapy dissemination research

Psychotherapy researchers are increasingly engaged in collaborations with clinical practitioners and mental health administrators. Each party brings its own perspectives, values, and agendas to bear in these encounters. Viable research—practice collaborations depend on understanding and negotiating some of the tensions in these relationships. In this article, we discuss the contexts that prevail for various participants in a psychotherapy dissemination study as well as the values, goals, costs, and benefits related to research participation. This article is a collaboration among the researchers, mental health administrators, therapists, and clients involved in an ongoing treatment dissemination study. Our recommendations for research—practice collaborations are based on our experiences and dialogues over the course of this study.     

A naturalistic longitudinal evaluation of counselling in primary care

This study evaluated the effectiveness of generic counselling in a primary healthcare setting during three months of counselling and followed up the patients' progress after counselling had finished for the next twenty-one months. Questionnaires were completed by patients within the Dorset Primary Care counselling service on referral to counselling and at set points afterwards. A naturally occurring waiting-list group was compared with patients receiving counselling at baseline and three months. Measurements were taken of patients' psychiatric symptomatology, quality of life (QOL) and self-esteem. Patients who received counselling made highly significant improvements compared with those on the waiting list. These improvements were maintained throughout the long-term follow-up. This would indicate that generic counselling has positive effects that can be maintained for a long period of time after counselling has been completed.
