A strategy for assessing closure

This paper looks at an argument strategy for assessing the epistemic closure principle. This is the principle that says knowledge is closed under known entailment; or (roughly) if S knows p and S knows that p entails q, then S knows that q. The strategy in question looks to the individual conditions on knowledge to see if they are closed. According to one conjecture, if all the individual conditions are closed, then so too is knowledge. I give a deductive argument for this conjecture. According to a second conjecture, if one (or more) condition is not closed, then neither is knowledge. I give an inductive argument for this conjecture. In sum, I defend the strategy by defending the claim that knowledge is closed if, and only if, all the conditions on knowledge are closed. After making my case, I look at what this means for the debate over whether knowledge is closed.     

A Brief Scale for Measuring “Behavioral Inhibition to the Unfamiliar” in Children

The behavioral inhibition scale (BIS) is a brief rating scale for measuring behavioral inhibition in children. The present study examined the test–retest stability of the BIS in a sample of 7–12-year-olds consisting of inhibited and non-inhibited children (N = 83). Results demonstrated that the BIS scores were fairly stable over a 2-year period, with a test–retest correlation of .77. Further, the BIS scores of inhibited children significantly increased over the 2-year period, whereas those of the non-inhibited comparison group significantly decreased. Finally, the BIS was in a theoretically meaningful way associated with temperamental traits as measured by the Rothbart scales. Altogether, these results provide support for the reliability and validity of the BIS.     

Depression and engagement in a residential home for the elderly

Traditional residential care environments for the elderly have been criticized because of the observed low levels of residents' engagement. Behavioural models of depression suggest an inverse relationship between engagement in pleasant activities and depression. The present study examined the relationship between depression and engagement in the residents of a home for the elderly. Correlational analyses indicated no relationship between level of depression and level of engagement but an association was found between level of depression and engagement in activities subjectively most enjoyed. There was considerable variation in the residents' perception of their behaviour; some residents viewed active engagement negatively whilst clearly enjoying behaviour that is technically disengaged. It is suggested that the results of the study emphasize the importance both of individual differences in behaviour and of covert behaviour. Implications for the engagement concept are discussed. In particular it is suggested that programmes in care environments aimed at increasing engagement in order to enhance the quality of life should focus more on the individual and on his perception of his behaviour.     

Affect as a mediator of attributional egotism

A three-stage model of the relationships among achievement outcomes, outcome-related affect, attribution, and emotion is tested in two studies. It is suggested that success and failure elicit positive and negative affective states due to prior conditioning. These affective states then lead to an attribution process that serves to defend and enhance self-esteem. Next, emotional labels are chosen that are consistent with the affective states and the attributions. Two studies were designed to test the proposed relationships among achievement outcomes, affective states, and attributions. In the first study, subjects received information indicating that they were strongly or mildly aroused as a result of receiving outcome feedback on an achievement task. The results indicated that low arousal reduced egotistical attributions to internal factors. In the second study, subjects either succeeded or failed on an achievement task. Half of the subjects were provided with an opportunity to misattribute the arousal elicited by their outcomes to an irrelevant source. Subjects in the misattribution condition made less egotistical attributions to external factors than subjects who were given no opportunity to misattribute their arousal. The results of both studies suggest that outcome-related affect mediates the relationship between outcomes and attributions in achievement situations.     

The use of a double-blind drug trial in family therapy to demedicalize a problem

A family therapy approach to a problem that had led previous clinicians to diagnose and treat a child as 'hyperkinetic', is described. The resistance to change that the preceding diagnosis had inculcated, is described. A method of overcoming this resistance by active involvement of the family in a double-blind trial of the drug treatment, was devised and used concurrently with a structural form of family therapy.     

A unified approach to exploratory factor analysis with missing data,nonnormal data,and in the presence of outliers

Factor analysis is regularly used for analyzing survey data. Missing data, data with outliers and consequently nonnormal data are very common for data obtained through questionnaires. Based on covariance matrix estimates for such nonstandard samples, a unified approach for factor analysis is developed. By generalizing the approach of maximum likelihood under constraints, statistical properties of the estimates for factor loadings and error variances are obtained. A rescaled Bartlett-corrected statistic is proposed for evaluating the number of factors. Equivariance and invariance of parameter estimates and their standard errors for canonical, varimax, and normalized varimax rotations are discussed. Numerical results illustrate the sensitivity of classical methods and advantages of the proposed procedures.This project was supported by a University of North Texas Faculty Research Grant, Grant #R49/CCR610528 for Disease Control and Prevention from the National Center for Injury Prevention and Control, and Grant DA01070 from the National Institute on Drug Abuse.

Why misinformation is more likely to be recognised over time: A source monitoring account

Although memory for actual events tends to be forgotten over time, memory for misinformation tends to be retrieved at a stable rate over long delays or at a rate greater than that found immediately after encoding. To examine whether source monitoring errors contribute to this phenomenon, two experiments investigated subjects' memory for the source of misinformation at different retention intervals. Subjects viewed a slide presentation, read a narrative containing misinformation, and, either 10 minutes or 1 week later, completed a recognition test about details seen in the slides and about the source of these details. After the longer retention interval in both experiments, participants were more likely to agree that they had seen misleading information and were also more likely to incorrectly associate the misinformation with the slide event. Theoretical implications of these findings are considered.     

Why Do Churches Become Empty,While New Age Grows? Secularization and Religious Change in the Netherlands

Research from the Netherlands has pointed out that the increased popularity of New Age since the 1960s by no means compensates for the dramatic decline of the Christian churches. From a theoretical point of view, however, it is more important to study why those remarkably divergent developments have occurred in the first place. This article does this by analyzing survey data collected among the Dutch population at large in 1998, focusing on a comparison of the young and the elderly. It is concluded, first, that there are no indications that the decline of the Christian tradition has been caused by a process of rationalization. Second, the decline of the Christian tradition and the growth of nonreligiosity as well as New Age are caused by increased levels of moral individualism (individualization). Implications for the sociological analysis of cultural and religious change are discussed.     

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.     

Playing Mating Games in Foreign Cultures: A Conceptual Framework and an Experimental Paradigm for Inductive Trivariate Inference

A conceptual framework is presented for studying trivariate inference, in which the influence of a primary independent factor, x, on a dependent variable, y, depends on a secondary factor, z. In two experiments, this was operationalized as the contingency between mating strategies, x, and mating success, y, for targets stemming from different tribes, z. In Experiment 1, z was manipulated to produce four contingency types: control, orthogonal, suppressor, and spurious correlations. Performance variation was not restricted by encoding capacity; explicit and implicit measures were more accurate at the trivariate level than at the bivariate level of assessment. Aside from normal regression effects, neither task complexity nor competition among influence factors led to impaired performance. Impairment was evident mainly in a radical discounting effect for spurious correlations due to representational conflicts. Experiment 2 demonstrates that the difficulties with spurious correlations can be overcome when temporal cues disambiguate the joint influence of x and z on y.
