Detecting differential item functioning with confirmatory factor analysis and item response theory: toward a unified strategy

In this article, the authors developed a common strategy for identifying differential item functioning (DIF) items that can be implemented in both the mean and covariance structures method (MACS) and item response theory (IRT). They proposed examining the loadings (discrimination) and the intercept (location) parameters simultaneously using the likelihood ratio test with a free-baseline model and Bonferroni corrected critical p values. They compared the relative efficacy of this approach with alternative implementations for various types and amounts of DIF, sample sizes, numbers of response categories, and amounts of impact (latent mean differences). Results indicated that the proposed strategy was considerably more effective than an alternative approach involving a constrained-baseline model. Both MACS and IRT performed similarly well in the majority of experimental conditions. As expected, MACS performed slightly worse in dichotomous conditions but better than IRT in polytomous cases where sample sizes were small. Also, contrary to popular belief, MACS performed well in conditions where DIF was simulated on item thresholds (item means), and its accuracy was not affected by impact.     

Simple and associative recognition memory in the hippocampal region

Although it is well established that the hippocampal region is involved in the formation of declarative memory, the exact nature of its involvement is unclear. One view is that the hippocampal region is involved only in tasks that require the formation or use of associations. According to this view, the hippocampal region is not involved in traditional tests of recognition memory. An alternative view is that the hippocampal region combines and extends the processing carried out by structures in the parahippocampal gyrus and that it is involved in all forms of declarative memory, including recognition memory. Using event-related functional magnetic resonance imaging (fMRI), we observed hippocampal activity during both traditional and associative recognition memory tasks. Critically, the hippocampal region was no more active in the associative recognition task than in the traditional recognition task.     

Eye See What You Are Saying: Testing Conversational Influences on the Information Gleaned from Home‐Loan Disclosure Forms

The federal government mandates the use of home‐loan disclosure forms to facilitate understanding of offered loans, enable comparison shopping, and prevent predatory lending. Predatory lending persists, however, and scant research has examined how salespeople might undermine the effectiveness of these forms. Three eye‐tracking studies (a laboratory simulation and two controlled experiments) investigated how conversational norms affect the information consumers can glean from these forms. Study 1 was a laboratory simulation that recreated in the laboratory; the effects that previous literature suggested is likely happening in the field, namely, that following or violating conversational norms affects the information that consumers can glean from home‐loan disclosure forms and the home‐loan decisions they make. Studies 2 and 3 were controlled experiments that isolated the possible factors responsible for the observed biases in the information gleaned from these forms. The results suggest that attentional biases are largely responsible for the effects of conversation on the information consumers get and that perceived importance plays little to no role. Policy implications and how eye‐tracking technology can be employed to improve decision‐making are considered. Copyright © 2015 John Wiley & Sons, Ltd.     

Do Violent Acts Equal Abuse? Resolving the Gender Parity/Asymmetry Dilemma

This commentary revisits a core dilemma in “Controversies involving Gender and Intimate Partner Violence in the United States” by Langhinrichsen-Rohling (2010), how to reconcile gender parity in the use of force by partners with the gender asymmetry in the dynamics and effects of partner abuse. This dilemma is a byproduct of a domestic violence paradigm that confounds the normative use of violence in families and relationships and the types of partner assault and coercive control targeted by the advocacy movement. I argue that the dimensions of abuse victims present at points of service contradict the basic assumptions of the paradigm and outline an alternative model of coercive control that sets violent acts in their historical, experiential and political context.     

The science of ethics: Deception, the resilient self, and the APA code of ethics, 1966-1973

This paper has two aims. The first is to shed light on a remarkable archival source, namely survey responses from thousands of American psychologists during the 1960s in which they described their contemporary research practices and discussed whether the practices were "ethical." The second aim is to examine the process through which the American Psychological Association (APA) used these survey responses to create principles on how psychologists should treat human subjects. The paper focuses on debates over whether "deception" research was acceptable. It documents how members of the committee that wrote the principles refereed what was, in fact, a disagreement between two contemporary research orientations. The paper argues that the ethics committee ultimately built the model of "the resilient self" into the APA's 1973 ethics code. At the broadest level, the paper explores how prevailing understandings of human nature are written into seemingly universal and timeless codes of ethics.     

Political Liberalism and Male Supremacy

In Equal Citizenship and Public Reason, Watson and Hartley dispute the claim that Rawls’s doctrine of political liberalism must tolerate gender hierarchy because it counts conservative and orthodox religions as reasonable comprehensive doctrines. I argue that their defense in fact contains two arguments, both of which fail. The first, which I call the ‘Deliberative Equality Argument’, fails because it does not establish conclusively that political liberalism’s demand for equal citizenship forbids social practices of domination, as the authors contend. The second, which I call the ‘Equal Liberties Argument’, fails because it supports a particular version of political liberalism and not the doctrine itself.     

Sex Differences in Response to Marijuana in a Social Setting

Due to the failure to include women in the subject samples of most experimental investigations of the effects of cannabis, the possibility exists that the data obtained on this social intoxicant are applicable to only 49% of the population. Those few studies that have compared males and females have focused on performance variables and have demonstrated very few differences. It was hypothesized that the most likely area for male/female marijuana differences would be that of social interactions and behaviors related to these interactions.
In a relaxed, informal atmosphere, Es videotaped the social interactions of groups of female friends, female strangers, male friends, or male strangers as they smoked coltsfoot, placebo, and marijuana. In addition to social-condition and drug-condition differences, we obtained statistically significant effects indicating that the women responded both to the social situations and to the drug differently from the men. In general, the women interacted with each other more positively than did the men. These effects were paralleled by sex differences in mood, person perception, and even in how pleasurable or annoying the experimental tasks were.
These data are of import not only in the area of cannabis research but in the field of social interactions and the study of female/male differences as well.
