Truth-Tracking by Belief Revision

Studia Logica - We study the learning power of iterated belief revision methods. Successful learning is understood as convergence to correct, i.e., true, beliefs. We focus on the issue of...     

Observing home-visiting quality across time: A longitudinal reliability study of the Home Visit Rating Scales

Empirical examination of home-visiting quality over time is lacking in the research literature. To this end, this study examined the most recent edition of a widely used observational measure of home-visiting quality, the Home Visit Rating Scales (HOVRS), over four repeated assessments spanning an average of 6 months. Psychometric quality for the HOVRS Total and Home Visitor Practice Scales, including item ratings and calculated scores, across time was demonstrated. Stability indicators for the Family Engagement Scales varied, with superior reliability often indicated for individual ratings over the calculated score. The exploration of interrelationships among family demographics and change in HOVRS scores over time were largely insignificant. Interestingly, a decline in the Home Visitor Practice Scale significantly related to increased symptoms of maternal depression, possibly suggesting that home-visitors’ focus shifted from children's needs to those of parent s when mental health concerns were observed. Although this study is an examination of one program model and poses limited generalizability, it sets the stage for advancing the HOVRS and longitudinal measurement of home-visiting quality.     

Roles and relationships: On whether social roles ground associative reasons

A common theory of associative reasons is that they attach to a social role, and when an individual identifies with that role, she acquires the attached reasons. I argue that associative reasons are different in kind from those provided by social roles. Social roles are self‐referential rather than interpersonal. That is, role reasons apply to someone depending on whether or how the individual inhabits her role, rather than whether or how she participates in a relationship with another individual. A justification of associative reasons should start from a theory of relationships' normative significance, such as its shared history. Finally, I give a brief account of the normative significance of shared history, psychological connectedness. Shared history matters in virtue of the connectedness it produces between people.     

The centrality of the female body in Brazilian culture: Evangelical and Muslim responses

This article aims to analyse how both Evangelical and Islamic religions deal with a central aspect of the construction of the Brazilian national identity: the body. The Brazilian religious field is exposed to this cultural value and reacts to it in different ways. While Islam preaches female modesty, involving the ‘concealment’ of the body and its forms, Evangelicals reinforce part of the Brazilian culture of appreciation and care for physical attributes, albeit using the rhetoric of doing so with moderation and modesty. The data presented here were collected through interviews with religious leaders and through participant observation in the Baptist Church of Lagoinha, in Belo Horizonte, and the Islamic Youth League, in São Paulo, Brazil.     

Reporting ethical practices in journal articles

Little attention has focused on the reporting of ethical research practices in journal articles. In Study 1, published articles in 2 psychopathology journals were reviewed to ascertain the types of ethical research information that were reported. In Study 2, a survey was sent to authors in Study 1 to determine which ethical practices they engaged in, if they reported this information, and reasons for not including this information in their article. In general, there is a great variability regarding the types of ethical research practices reported in journal articles. Commonly cited reasons for not including ethical research practice information in the articles included the need for brevity, belief that it was common practice, and lack of relevance for the project. These results suggest that there is no standard practice for reporting research practices in journal articles and great variability in the implementation of procedures that are generally considered standard.     

Are self-enhancing cognitions associated with healthy or unhealthy biological profiles?

Self-enhancement is variously portrayed as a positive illusion that can foster health and longevity or as defensive neuroticism that can have physiological-neuroendocrine costs. In a laboratory stress-challenge paradigm, the authors found that high self-enhancers had lower cardiovascular responses to stress, more rapid cardiovascular recovery, and lower baseline cortisol levels, consistent with the positive illusions predictions and counter to the predictions of the defensive neuroticism position. A second set of analyses, replicating the "illusory mental health paradigm" (J. Shedler, M. Mayman, & M. Manis, 1993), also did not support the defensive neuroticism hypothesis. The association between self-enhancement and cortisol was mediated by psychological resources; analyses of the cardiovascular results provided no definitive mediational pathway. Discussion centers on the potential stress-buffering effects of self-enhancing beliefs.     

Understanding adolescent worry: the application of a cognitive model

The relationship between worry and 4 cognitive variables, intolerance of uncertainty, positive beliefs about worry, negative problem orientation, and cognitive avoidance, was examined in an adolescent sample of 528 boys and girls aged 14–18. The participants completed questionnaires assessing worry, somatic anxiety symptoms, and the variables mentioned above. The results show that (a) intolerance of uncertainty, positive beliefs about worry, and negative problem orientation each account for a significant amount of variance in adolescent worry scores in the multiple regression, and (b) the discriminant function derived from the 4 variables is effective in classifying moderate and high worriers into their respective groups (72.8% correct classification). Furthermore, analyses demonstrate that intolerance of uncertainty has the strongest association with worry scores and is the most important variable in discriminating between moderate and high adolescent worriers. These results suggest that intolerance of uncertainty plays a key role in our understanding of adolescent worry.     

Portrait of the self-enhancer: well adjusted and well liked or maladjusted and friendless?

Research has variously portrayed self-enhancement as an indicator of narcissistic defensiveness or as a concomitant of mental health. To address this controversy, the present study used multiple measures of self-enhancement along with multiple measures and judges of mental health, comprehensively assessing their relationship. The results indicated that self-enhancement is positively associated with multiple indicators of mental health and with a more favorable impact on others. Discussion centers on a reconciliation of discrepant portraits of the self-enhancer.
