Muller’s Critique of the Argument for Aim-Oriented Empiricism

For over 30 years I have argued that we need to construe science as accepting a metaphysical proposition concerning the comprehensibility of the universe. In a recent paper, Fred Muller criticizes this argument, and its implication that Bas van Fraassen’s constructive empiricism is untenable. In the present paper I argue that Muller’s criticisms are not valid. The issue is of some importance, for my argument that science accepts a metaphysical proposition is the first step in a broader argument intended to demonstrate that we need to bring about a revolution in science, and ultimately in academic inquiry as a whole so that the basic aim becomes wisdom and not just knowledge.     

Emotion as motion: asymmetries in approach and avoidant actions

To emote literally means to move or prepare for action. A large body of research indicates that flexor and extensor movements are conditionally associated with approach- and avoidance-related motivations. It has also been widely argued that approach and avoidant motivations are asymmetrically instantiated in the left and right hemispheres, respectively. Nevertheless, to date, these literatures remain largely separate. In the present investigation, flexor and extensor movements that were visuospatially contextualized as being directed toward the self and away from the self were observed to be asymmetrically represented in the "approach" and "avoidance" hemispheres. Moreover, this pattern of hemispheric specialization was manifested to a greater degree the higher participants' self-reported level of daily positive affect and the lower their self-reported level of dispositional anxiety. Collectively, these findings have direct implications for models of embodied emotional and perceptual processing, as well as for investigations of individual differences in emotional disposition.     

Bias in cross-sectional analyses of longitudinal mediation

Most empirical tests of mediation utilize cross-sectional data despite the fact that mediation consists of causal processes that unfold over time. The authors considered the possibility that longitudinal mediation might occur under either of two different models of change: (a) an autoregressive model or (b) a random effects model. For both models, the authors demonstrated that cross-sectional approaches to mediation typically generate substantially biased estimates of longitudinal parameters even under the ideal conditions when mediation is complete. In longitudinal models where variable M completely mediates the effect of X on Y, cross-sectional estimates of the direct effect of X on Y, the indirect effect of X on Y through M, and the proportion of the total effect mediated by M are often highly misleading.     

Once a Utilitarian,Consistently a Utilitarian? Examining Principledness in Moral Judgment via the Robustness of Individual Differences

Although individual differences in the application of moral principles, such as utilitarianism, have been documented, so too have powerful context effects—effects that raise doubts about the durability of people's moral principles. In this article, we examine the robustness of individual differences in moral judgment by examining them across time and across different decision contexts. In Study 1, consistency in utilitarian judgment of 122 adult participants was examined over two different survey sessions. In Studies 2A and 2B, large samples (Ns = 130 and 327, respectively) of adult participants made a series of 32 moral judgments across eight different contexts that are known to affect utilitarian endorsement. Contrary to some contemporary theorizing, our results reveal a strong degree of consistency in moral judgment. Across time and experimental manipulations of context, individuals maintained their relative standing on utilitarianism, and aggregated moral decisions reached levels of near‐perfect consistency. Results support the view that on at least one dimension (utilitarianism), people's moral judgments are robustly consistent, with context effects tailoring the application of principles to the particulars of any given moral judgment.     

Does It Help or Hinder? Technology and Its Role in Healing Post Affair

For couples experiencing infidelity, technology can be either a source of comfort or a constant threat. Technology has created an atmosphere where individuals have access to more people, in more ways, and at more times than ever before. While this accessibility has increased partners' ability to connect with each other, it has also increased opportunities for infidelity and makes it easier to maintain an affair. From an attachment perspective, infidelity can lead to heightened sensitivities that alter how an individual experiences the availability, responsiveness, and engagement of their partner. Everyday interactions like text messages, phone calls, and computer use become potential threats that compromise the safety of the relationship. Using an extensive clinical vignette, this article highlights the systemic relationship between technology, attachment, and infidelity and provides clinicians with a framework to use when helping couples heal post affair.     

Sample size for multiple regression: obtaining regression coefficients that are accurate, not simply significant

An approach to sample size planning for multiple regression is presented that emphasizes accuracy in parameter estimation (AIPE). The AIPE approach yields precise estimates of population parameters by providing necessary sample sizes in order for the likely widths of confidence intervals to be sufficiently narrow. One AIPE method yields a sample size such that the expected width of the confidence interval around the standardized population regression coefficient is equal to the width specified. An enhanced formulation ensures, with some stipulated probability, that the width of the confidence interval will be no larger than the width specified. Issues involving standardized regression coefficients and random predictors are discussed, as are the philosophical differences between AIPE and the power analytic approaches to sample size planning.     

Joining a consumer society: Russian immigrant versus American materialism

• Regardless of their home country, immigrants to the United States often arrive in search of personal freedom and a share of the riches of this country. Prior research has identified a range of knowledge and skills that immigrants must acquire in order to navigate such a consumer society. One aspect of joining a consumer society that has not been addressed, however, is the role of material goods in one's life. The purpose of this paper is to examine the changing role, if any, of material goods in the lives of immigrants arriving in the United States from a non‐consumer society and to compare the level of materialism among such immigrants with that of Americans. The results of a study of 278 Soviet‐era Russian immigrants and 200 native‐born Americans indicate that at the time the immigrants arrived, they were just as materialistic as Americans and became no more materialistic, the longer they lived in the United States. Both Americans and Russians, however, became less materialistic with age. Copyright © 2006 John Wiley & Sons, Ltd.

     

The Influence of Community Violence on the Functioning of Women Experiencing Domestic Violence

The relationships among women’s experiences of domestic violence, community violence, and their mental health functioning were explored (N = 94). Social contagion theory was used to argue for the link between community violence and family violence. Results revealed that women’s experiences of domestic violence were not related to community violence. Furthermore, women’s mental health functioning was solely associated with their experiences of domestic violence, not with community violence. Results are discussed in terms of an ecological model of domestic violence and future directions for exploring linkages between neighborhood characteristics and individual experiences.     

Structural differences in parent and child reports of children's symptoms of depression and anxiety

Two cohorts of public elementary school children and their parents (assessed 3 years apart) completed child and parent forms of the Children's Depression Inventory (CDI) and the Revised Children's Manifest Anxiety Scale (RCMAS). Assessments were conducted twice, once during the fall (N = 562) and again during the spring (N = 630) of the 6th grade. Factor analyses revealed 3 factors for each measure. Two of the 3 parent CDI factors manifested some degree of congruence with their counterparts from the child CDI. Similarly, 2 of the 3 RCMAS factors were somewhat congruent across informant types. Differences between parent and child factor structures suggest that parents' and children's reports focus on somewhat different aspects of child psychopathology, and they can make qualitatively different contributions to the multiaxial assessment of children.
