Michael Huemer’s A Priori Defense of Metaethical Internalism

Versions of internalism have played important roles in metaethics, for example, in defending irrealist options such as emotivism. However, internalism is itself as controversial as the views it is used to defend. Standard approaches to testing the view, such as thought experiments about amoralists, have failed to gain consensus. Michael Huemer offers a defense of internalism of a different kind which he calls the “argument from interpretation.” He presents the argument as one Humeans could embrace, but versions could be accepted by others, including Huemer himself. The argument begins from the assumption that a certain principle of charity is true and knowable a priori. But it can only be known a priori if internalism is true. Hence internalism is true. In this paper I argue that this important argument fails. My main objection makes use of recent work in empirical psychology. Huemer needs the principle of charity to be known a priori. I argue that rather than being an a priori issue, it is an empirical one and that the empirical evidence is strong enough to undermine his argument for internalism.     

PREDICTORS OF SELF‐REPORTED GAINS IN A RELATIONSHIP‐BASED HOME‐VISITING PROJECT FOR MOTHERS AFTER CHILDBIRTH

We assessed mothers’ self‐reported gains from a postpartum home‐visiting (HV) project in which home visitors are volunteer mothers from the community. Hypotheses were that gains are positively related to (a) mothers’ felt‐closeness with their home visitor, (b) mothers’ level of sociodemographic risk, and (c) the home visitors’ preproject training in support services for families or children (Professionalism). One hundred sixty‐four clients returned written evaluations of the HV project. Items assessing gains were reduced to two factors: Improved Well‐Being (“Self”) and Improved Infant Care (“Infant”). Repeated measures general linear models, with Gains (Self, Infant) as the repeated measure, and multiple regression analyses evaluated the hypotheses. Across the sample, gains on both factors were moderate, although gain scores were higher regarding Self than for Infant. Results show that (a) Mothers’ felt‐closeness with their volunteer was strongly related to mothers’ gains; (b) high‐risk mothers gained more from the project than did mothers of lower risk, particularly regarding Infant Care; and (c) mothers visited by volunteers who were professionals reported more substantial gains than did mothers visited by volunteers who were not professionals. Findings can help explain variance in mothers’ gains from such projects and could be useful in improving their efficacy.     

Relative Earnings and Depressive Symptoms among Working Parents: Gender Differences in the Effect of Relative Income on Depressive Symptoms

The relationship between income and psychological well-being is well established. Yet, most of this research is conducted at the individual level without taking into account the role played by relative earnings at the couple level. In the present study we estimate the effect of share of family income on depressive symptoms of individuals. Specifically, we examine whether within-person change in the share of family income has differential effects on the level of depressive symptoms of mothers and fathers. Using data from the U.S. National Longitudinal Surveys of Youth (NLSY79), we follow the same individuals over 4 years and analyze their data using a cross-lagged structural equation model. Controlling for net income, we find that an increase in one’s share of family income is related to an increased level of depressive symptoms among mothers and a decreased level of depressive symptoms among fathers. When looking at a subsample of stay-at-home parents, we find that a change from providing some share of the family income to stay-at-home parent status over time is related to higher level of depressive symptoms among fathers but not mothers. Furthermore, we find that egalitarian gender ideology moderates this relationship for mothers but not for fathers. We discuss potential implications of our findings to the work-family and gender literature and to counselors and therapists who specialize in treating depression.     

Prosaccade and Antisaccade Paradigms in Persons with Alzheimer’s Disease: A Meta-Analytic Review

Persons with Mild Cognitive Impairment (MCI) are at high Alzheimer’s Disease (AD) risk but the development of sensitive measures to assess subtle cognitive decline in this population poses a major challenge for clinicians and researchers. Eye movement monitoring is a non-invasive, sensitive way to assess subtle cognitive processes in clinical populations. We conducted a critical review and a meta-analysis of the literature on pro and antisaccade paradigm in AD/MCI. The meta-analysis included 20 studies, all of which used the prosaccade paradigm and 13 of which studied the antisaccade paradigm as well. Our meta-analysis showed that AD but not MCI patients showed longer prosaccade latencies when compared to controls. While antisaccade latencies did not differentiate between patients from controls, antisaccade error rate were significantly increased among patients in comparison to controls in over 87% of the studies. These findings highlight antisaccade error rate as a reliable tool to distinguish inhibition abilities between AD/MCI and healthy older persons.
