Two kinds of naturalism in ethics

What are the conditions on a successful naturalistic account of moral properties? In this paper I discuss one such condition: the possibility of moral concepts playing a role in good empirical theories on a par with those of the natural and social sciences. I argue that Peter Railton’s influential account of moral rightness fails to meet this condition, and thus is only viable in the hands of a naturalist who doesn’t insist on it. This conclusion generalises to all versions of naturalism that give a significant role to a dispositional characterisation of moral properties. I also argue, however, that the epistemological and semantic motivations behind naturalism are consistent with a version of naturalism that doesn’t insist on the explanatory condition. The conclusion is that those naturalists who are attracted to accounts of moral properties such as Railton’s would do better not to insist on this\break condition.     

Adolescence and the Changing Context of Optimal Experience in Time: Italy 1986–2000

This study focused on the daily activities and related quality of experience of two distinct groups of Italian high school students analyzed in 1986 and 2000. Altogether, 120 participants, aged between 15 and 18, were administered the experience sampling method, a procedure providing on-line repeated samplings of daily time budget and associated quality of experience. In particular, attention was paid to optimal experience, characterized by a balance between environmental challenges and personal skills, intrinsic motivation, involvement, and well-being. In spite of the time gap, no major differences in the daily activity distribution were detected. Adolescents in both groups spent most of their time studying at school and at home, interacting, watching TV, carrying out maintenance, and engaging in structured leisure activities. The use of new technologies (computers, internet, mobile phones) emerged in the data gathered in 2000. As concerns the quality of experience, each daily activity showed a specific experiential profile recurring in both groups. Studying at home and engaging in structured leisure activities were primarily associated with optimal experience, as was using new technologies in 2000. These results shed light on students' preferential engagement in specific domains and allowed us to explore the active role of adolescents in shaping their future. Findings also highlighted the importance of providing adolescents with meaningful activities in order to foster their personal growth, well-being, and social integration.     

Observing home-visiting quality at scale with the home visit rating scales and a supervisor checklist in Peru

As home-visiting programs expand, there is a need to develop cost-effective tools to monitor their quality at scale. We compare the Home Visit Rating Scales (HOVRS), an instrument to measure home-visit process quality widely used in the United States, to a checklist designed for the Peruvian national home-visiting program, Cuna Mas. Both instruments were administered to a sample of 554 home visits and an equal number of mother–child dyads by their 176 home visitors. While the HOVRS was scored on video recordings of the visits by trained coders, the checklist was scored live by Cuna Mas supervisors. We assessed the validity of both measures in their first application in rural Peru, compared their performance, and selected a subset of items in the checklist to propose a simplified, shorter, and more cost-efficient instrument. To this end, we reorganized checklist items into constructs that best mapped those covered by the HOVRS and selected the highest performing according to predefined criteria. We found that both the HOVRS and the checklist had high reliability and acceptable levels of validity. We argue that the simplified checklist could prove useful for quality monitoring of service delivery of at-scale home-visiting programs and as a tool to support in-service training.

Mismaking memories: neural precursors of memory illusions in electrical brain activity

Memory illusions--vivid experiences of events that never occurred--could result from inaccuracies either in retrieving memories or in initially storing them. In two experiments, people studied lists of associated words that either did or did not induce later illusory (false) memories of associated but nonpresented lure words. The amplitude of the electrical brain activity during study of words (approximately 500-1,300 ms) that were themselves later correctly remembered reliably distinguished list words that led to such illusory memories from those that did not. This encoding difference associated with subsequent illusory memory (referred to as a DIM)--presumably reflecting item-specific encoding differences--is a neural precursor of memory illusions.     

Ethnic enclaves and the dynamics of social identity on the college campus: the good, the bad, and the ugly

The effects of membership in ethnic organizations and fraternities and sororities on intergroup attitudes were examined using a 5-wave panel study at a major, multiethnic university. The results showed that these effects were similar for both minority and White students. Membership in ethnic student organizations for minorities and Greek organizations for Whites was anteceded by the degree of one's ethnic identity, and the effects of membership in these groups were similar, although not identical, for both White and minority students. These effects included an increased sense of ethnic victimization and a decreased sense of common identity and social inclusiveness. Consistent with social identity theory, at least a portion of these effects were mediated by social identity among both White and minority students.     

Effects of increasing cognitive load on sustained attention tasks in schizophrenic disorders and schizotypy

In this study we analyze the attentional performance using different cognitive load attentional tasks: low-load cognition (0-CPT) and high-load cognition (DS-CPT). Participants were a group of schizophrenic patients and two groups of normal population psychometrically classified as low schizotypy and high schizotypy according to the SPQ. Our results show that schizophrenic patients were more sensitive to increments on cognitive load, being their attentional performace worse than the rest of the groups. The lack of significant findings in vigilance on the schizotypal traits group is discussed in terms of conceptual and methodological issues about the utility of psychometric strategies to identify vulnerable populations within the spectrum of the schizophrenic disorders.     

A new method for detecting causality in fMRI data of cognitive processing

One of the most important achievements in understanding the brain is that the emergence of complex behavior is guided by the activity of brain networks. To fully apply this theoretical approach fully, a method is needed to extract both the location and time course of the activities from the currently employed techniques. The spatial resolution of fMRI received great attention, and various non-conventional methods of analysis have previously been proposed for the above-named purpose. Here, we briefly outline a new approach to data analysis, in order to extract both spatial and temporal activities from fMRI recordings, as well as the pattern of causality between areas. This paper presents a completely data-driven analysis method that applies both independent components analysis (ICA) and the Granger causality test (GCT), performed in two separate steps. First, ICA is used to extract the independent functional activities. Subsequently the GCT is applied to the independent component (IC) most correlated with the stimuli, to indicate its causal relation with other ICs. We therefore propose this method as a promising data-driven tool for the detection of cognitive causal relationships in neuroimaging data.     

Perceived discrimination in the context of multiple group memberships

This study examined the joint impact of gender and ethnicity on expectations of general discrimination against oneself and one's group. According to the double–jeopardy hypothesis, women of color will expect to experience more general discrimination than men of color, White women, and White men because they belong to both a low–status ethnic group and a low–status gender group. Alternatively, the ethnic–prominence hypothesis predicts that ethnic–minority women will not differ from ethnic–minority men in their expectations of general discrimination because these expectations will be influenced more by perceptions of ethnic discrimination, which they share with men of color, than by perceptions of gender discrimination. All results were consistent with the ethnic–prominence hypothesis rather than the double–jeopardy hypothesis.
