Why I'm not a Humean

There is an inconsistency between the access we have to our conscious lives and the Humean thesis of causal generalism. This was first drawn attention to by John Hawthorne, whose argument withstands a number of objections. Nevertheless, it has weaknessess. The first premise must be weakened if Humeans are to be compelled to accept it, and consequently, the second premise will have to be stronger to retain validity. I shore up the case against Humeanism by providing revised premises along with new defences of them. I show why this also provides a lesson for non-Humeans about the epistemology of causal relations.     

Dividing attention between color and shape: Evidence of coactivation

When attention is divided between spatially distinct objects, the time-to detect a target decreases when two or more targets are present. This redundancy gain can be accounted for by an interactive race model (Mordkoff & Yantis, 1991) in which separate decisions are made about each object, but environmental contingencies among the objects can influence decision times. In the present study, we examined whether the model also accounts for performance when attention must be divided between stimulus attributes other than spatial location. Subjects made target-present responses when displays included a prespecified color, a prespecified letter, or both target features. The data violated the predictions of all separate-activations models, including the interactive race model. Two control experiments ruled out an alternative account based on task complexity. We conclude that coactivation occurs when target attributes from two separable dimensions are simultaneously present, but not when target attributes come from the same dimension. A modular hybrid of race and coactivation models is tentatively proposed.     

Redundancy gains and coactivation with two different targets: The problem of target preferences and the effects of display frequency

When a visual display contains two targets, both of which require the same response, reaction times (RTs) are faster than when only one target appears. This effect has previously been obtained regardless of whether the redundant targets are the same or different in shape, and in at least one set of two-target experiments, the redundancy gains have been larger for different targets (Grice & Reed, 1992). Experiments with two different targets have also revealed violations of the race-model inequality, suggesting that redundant targets coactivate the response (Miller, 1982). The present paper reexamines both of these findings, because both appear to be inconsistent with the interactive race model (Mordkoff & Yantis, 1991). Experiment 1 shows that the race-model inequality is not violated when the experimental design is free of biased contingencies; Experiment 1 also provides evidence that target preferences may artifactually produce the RT advantage fordifferent- oversame-target trials. Experiment 2, however, shows that the race-model inequality is violated when the frequencies of single- and redundant-target displays are equated (without introducing any biased contingencies), implying that the interactive race model cannot account for the results of experiments involving more than one type of target. Alternative loci for coactivation are briefly discussed.     

The voices in children's literature: The impact of gender on the moral decisions of storybook characters

The study examined the moral and self orientations of 212 male and female characters in 50 works of fiction for school-aged children. A modified version of Lyons' coding scheme was used for differentiating between Justice and Care moral orientations, and Separate/Objective and Connected self orientations. It was hypothesized that male characters would demonstrate Justice morality and a Separate/Objective self, whereas female characters would demonstrate Care morality and a Connected self, regardless of sex of author. The results confirmed the hypotheses. The importance of literature in providing symbolic models of moral decisioning and the need to expand children's moral orientations beyond gender-linked stereotypes was discussed.An earlier version of this paper was presented at the annual meeting of the American Educational Research Association, April 1988, New Orleans, Louisiana.     

Independent influences of verbalization and race on the configural and featural processing of faces: a behavioral and eye movement study

Describing a face in words can either hinder or help subsequent face recognition. Here, the authors examined the relationship between the benefit from verbally describing a series of faces and the same-race advantage (SRA) whereby people are better at recognizing unfamiliar faces from their own race as compared with those from other races. Verbalization and the SRA influenced face recognition independently, as evident on both behavioral (Experiment 1) and eye movement measures (Experiment 2). The findings indicate that verbalization and the SRA each recruit different types of configural processing, with verbalization modulating face learning and the SRA modulating both face learning and recognition. Eye movement patterns demonstrated greater feature sampling for describing as compared with not describing faces and for other-race as compared with same-race faces. In both cases, sampling of the eyes, nose, and mouth played a major role in performance. The findings support a single process account whereby verbalization can influence perceptual processing in a flexible and yet fundamental way through shifting one's processing orientation.     

Phase Changes in the BRCA Policy Domain

The recent US Supreme Court ruling against gene patenting has been accompanied by the passage at the federal level of the Patient Protection and Affordable Care Act, both events representing a thawing or phase change in policies that will now make preventive techniques, such as BRCA genetic testing to predict risk for familial breast and ovarian cancer, more affordable and accessible. Authors including Yun-Han Huang in this journal have noted the judicial ruling is one step—a significant one—in the process of patent system reform. This commentary links such changes with policy formation and action taken by members of diverse religious communities in the aftermath of the Human Genome Project and continuing in today’s genome sequencing area. Religious engagement has acted as a catalyzing force for change in the creation and dissemination of genetic developments. Religious perspectives are needed to solve the new ethical dilemmas posed by population screening for BRCA mutations and the rise of direct-to-consumer and provider marketing of such genetic tests, which have far-reaching consequences at the individual, family, and societal levels.     

The Role of Religious Values in Decisions About Genetics and the Public’s Health

The latest health care legislation, which promotes prevention and health screening, ultimately depends for its success on recognition of people’s values concerning the technologies being employed, not just the interventions’ technical virtues. Values concerning the deterministic nature of a condition and what groups should be targeted rest on a sense of what is morally, often religiously right in a given health circumstance. This paper looks at a number of leading-edge case examples—breast cancer genetic screening and family decision-making, and newborn screening and biobanks—in examining how the choices made at the individual, family, and societal levels rest on faith in a higher source of efficacy and moral perspectives on the measures that can be taken. Qualitative responses expressing people’s attitudes toward these technologies underscore the importance of considering faith-based values in individual decisions and collective policies on their use. These examples are considered in the context of the historic interplay between science and religion and recent definitions and models of health which incorporate physical, emotional, and social elements, and most importantly, are expanding to incorporate the religious and spiritual values domains.     

The perils of protection: vulnerability and women in clinical research

Subpart B of 45 Code of Federal Regulations Part 46 (CFR) identifies the criteria according to which research involving pregnant women, human fetuses, and neonates can be conducted ethically in the United States. As such, pregnant women and fetuses fall into a category requiring “additional protections,” often referred to as “vulnerable populations.” The CFR does not define vulnerability, but merely gives examples of vulnerable groups by pointing to different categories of potential research subjects needing additional protections. In this paper, I assess critically the role of this categorization of pregnant women involved in research as “vulnerable,” both as separate entities and in combination with the fetuses they carry. In particular, I do three things: (1) demonstrate that pregnant women qua pregnancy are either not “vulnerable” according to any meaningful definition of that term or that such vulnerability is irrelevant to her status as a research participant; (2) argue that while a fetus may be vulnerable in terms of dependency, this categorization does not equate to the vulnerability of the pregnant woman; and (3) suggest that any vulnerability that appends to women is precisely the result of federal regulations and dubious public perceptions about pregnant women. I conclude by demonstrating how this erroneous characterization of pregnant women as “vulnerable” and its associated protections have not only impeded vital research for pregnant women and their fetuses, but have also negatively affected the inclusion of all women in clinical research.
