Mill on Happiness: A question of method

There are issues in Reid scholarship as well as the primary texts that seem to suggest that Reid is not a direct realist about visual perception. In this paper, I examine two key issues – colour perception and visible figure – and attempt to defend the direct realism of Reid's theory through an interpretation of ‘directness’ as well as what Reid calls ‘acquired perception’, which is ‘mediate’ in that it requires prior perception of signs, but nonetheless constitutes direct perception.     

Contrastive confirmation: some competing accounts

I outline four competing probabilistic accounts of contrastive evidential support and consider various considerations that might help arbitrate between these. The upshot of the discussion is that the so-called ??Law of Likelihood?? is to be preferred to any of the alternatives considered.     

Is IQ in Childhood Associated with Suicidal Thoughts and Attempts? Findings from The Mater University Study of Pregnancy and Its Outcomes

This study explores associations of IQ at age 14 with adult symptoms of suicidal thoughts and attempts at age 21. Analysis was based on the Mater University Study of Pregnancy and its outcomes, an Australian prospective birth cohort study started in Brisbane Australia in 1981. We assessed associations with suicide thoughts, plans, and attempts. We used two measures of IQ: the Raven's Standard Progressive Matrices and the Wide Range Achievement Test. In multivariable analyses, there was an inverse association between Raven's IQ and suicide thoughts, plans, and attempts, but no strong evidence of an association between the WRAT3 and the three suicidal items. Specific aspects of intelligence may be associated with suicidal thoughts, plans, and attempts.     

Is the study about spontaneous attention to exact quantity based on studies of spontaneous focusing on numerosity?

Li and Baroody present a study in which they investigate toddlers’ spontaneous attention to exact quantity without acknowledging how previous studies of spontaneous focusing on numerosity (SFON) are related to their concept and methods. In this commentary requested by the European Journal of Developmental Psychology, we argue that the concept and the methods of spontaneous attention to exact quantity in the study of Li and Baroody clearly arise from previous research on SFON, as the authors have previously noted in their paper published in 2008. It is highly questionable whether their approach can be theoretically or methodologically dissociated from the previous research on SFON tendency to the extent that it is necessary to use an alternative name for the concept in their study.     

Studies on spontaneous attention to number (SAN) are based on spontaneous focusing on numerosity (SFON)

Li and Baroody presented a study in which they investigate children’ spontaneous attention to exact quantity without acknowledging how previous studies of spontaneous focusing on numerosity (SFON) are related to their concept and methods. The authors’ reaction to our pointing this out makes it is clear that SFON research has had foundational role in the development of Baroody and his colleagues spontaneous attention to number (SAN) idea. Thus the authors must acknowledge the SFON literature as the substantial part of their theoretical and methodological construct. The latest definition of SAN states this undeniably. “SAN is the attentional process that underlies exact number recognition initiated by the mathematical thinking triggered by SFON (e.g., attention to “threeness” directed by conceptual knowledge of “three” activated by SFON).” Furthermore, in their response, Dr Baroody and Dr Li admit that “An awareness of the SFON literature did help us explicitly recognize that, given the ambiguous instructions that do not explicitly direct a child’s attention to number, both the nonverbal production and matching tasks were useful in assessing unguided or spontaneous attention to a number.” It is surprising that in their response to the European Journal of Educational Psychology, the authors maintain their claim that they have cited the SFON literature adequately in their study about SAN.     

The Irreducibility of Iterated to Single Revision

After a number of decades of research into the dynamics of rational belief, the belief revision theory community remains split on the appropriate handling of sequences of changes in view, the issue of so-called iterated revision. It has long been suggested that the matter is at least partly settled by facts pertaining to the results of various single revisions of one’s initial state of belief. Recent work has pushed this thesis further, offering various strong principles that ultimately result in a wholesale reduction of iterated to one-shot revision. The present paper offers grounds to hold that these principles should be significantly weakened and that the reductionist thesis should ultimately be rejected. Furthermore, the considerations provided suggest a close connection between the logic of iterated belief change and the logic of evidential relevance.     

A portable defense of the Procreation Asymmetry

Abstract

The Procreation Asymmetry holds that we have strong moral reasons not to create miserable people for their own sakes, but no moral reasons to create happy people for their own sakes. To defend this conjunction against an argument that it leads to inconsistency, I show how recognizing ‘creation’ as a temporally extended process allows us to revise the conjuncts in a way that preserves their intuitive force. This defense of the Procreation Asymmetry is preferable to others because it does not require us to take on controversial metaphysical or metaethical commitments – in other words, it has the theoretical virtue of portability.     

Self-Efficacy in Service-Learning Community Action Research: Theory, Research, and Practice

The purpose of this article is threefold: In the first section, an overview of research and theory on the self-efficacy construct is provided, and the central role of self-efficacy in service-learning community action research is demonstrated. The second section reviews over 10 years of research validating the Community Service Self-Efficacy Scale (CSSES), which measures the individual’s confidence in his or her own ability to make clinically (meaningfully) significant contributions to the community through service. Within the context of this review, recent (previously unpublished) validation research is also reviewed. Alternate versions of the CSSES, each of which was developed for a specific purpose, are presented. The third section provides recommendations for further research focused on (a) validating the CSSES and (b) examining self-efficacy as an outcome, moderator, and mediating variable in service-learning community action research.     

The Psychosocial Vulnerability Model of Hostility as a Predictor of Coronary Heart Disease in Low-income African Americans

The current study examined social support and stress as mediators of the hostility—coronary heart disease (CHD) relationship as suggested by the psychosocial vulnerability model in a sample of low-income African Americans. Among 95 CHD patients and 30 healthy controls, hostility was negatively correlated with social support, but was not related to minor stress. CHD patients endorsed higher levels of hostility; however, the relationship between hostility and CHD status was diminished once stress and social support were included in the model. This study lends partial support for the psychosocial vulnerability model of hostility in African Americans, but suggests that the relationship between hostility and stress may be impacted by socioeconomic status.
