Further validation of a single‐item measure of social identification

We examine the validity and reliability of a single‐item measure of social identification (SISI). Convergent validity is shown with significant positive correlations with previously published unidimensional and multidimensional measures of in‐group identification and other group‐relevant measures (e.g., entitativity and collective self‐esteem). Divergent validity is shown via nonsignificant correlations with social desirability measures. Predictive validity is shown with positive correlations with group‐relevant behavior (e.g., volunteerism and voting). External validity is shown with correlations with other in‐group identification measures in a community sample. The reliability of the scale is shown by examining scores of the SISI for six different identities at three points in time. Copyright © 2013 John Wiley & Sons, Ltd.

This article introduces a review symposium on Sexuality in Classical South Asian Buddhism. I situate this book in the newly emerging field of Buddhism and sexuality, and also provide a discussion of previous works by the author that led to the current volume under review. I also provide a broad overview of the book itself for those unfamiliar with the work. The responses in this symposium are offered by Sarah H. Jacoby (Northwestern University), John Powers (Deakin University), and Amy Paris Langenberg (Eckerd College).     

Anticipatory baseline effects and information integration in visual world studies

Researchers often conduct visual world studies to investigate how listeners integrate linguistic information with prior context. Such studies are likely to generate anticipatory baseline effects (ABEs), differences in listeners' expectations about what a speaker might mention that exist before a critical speech stimulus is presented. ABEs show that listeners have attended to and accessed prior contextual information in time to influence the processing of the critical speech stimulus. However, further evidence is required to show that the information actually did influence subsequent processing. ABEs can compromise the validity of inferences about information integration if they are not appropriately controlled. We discuss four solutions: statistical estimation, experimental control, elimination of “on-target” trials, and neutral gaze. An experiment compares the performance of these solutions, and suggests that the elimination of on-target trials introduces bias in the direction of ABEs, due to the statistical phenomenon of regression toward the mean. We conclude that statistical estimation, possibly coupled with experimental control, offers the most valid and least biased solution.     

The role of working memory in the metaphor interference effect

Participants took longer to judge that metaphors (e.g., an insult is a razor, memory is a warehouse) were literally false than to judge that scrambled sentences (e.g., an insult is a warehouse) were false. This result is the metaphor interference effect (MIE). It demonstrates that metaphor processing is automatic. In this experiment, we found that the magnitude of the MIE is predicted by working memory (WM) capacity, with higher WM yielding a smaller MIE. This suggests that although metaphor comprehension is automatic, the early processing of metaphors is controllable by executive mechanisms. We relate our results to Kintsch’s (2000, 2001) predication model. Specifically, we suggest that mechanisms of WM influence metaphor processing by affecting the effectiveness of the construction-integration process that identifies common properties between topics and vehicles. WM also influences the speed with which meanings are identified as literal or figurative.     

Modeling collective choice: decision‐making on complex intellective tasks

Three studies examined group problem‐solving on complex intellective tasks. In Study 1, a decision model proposed by Laughlin and Hollingshead ( 1995 ) provided the best fit to actual group choices. This study also compared three‐person group versus individual performance with time constrained and number of problems unconstrained, with individuals solving non‐significantly more problems and groups obtaining significantly superior trials‐to‐solution scores. In Study 2, one member of each group was given additional information on how to perform the task and member extroversion was measured. Neither factor significantly impacted the decision‐making process. In Study 3, task expertise was assessed prior to the group interaction. Results indicate that group members were twice as likely to adopt an option proposed by an expert compared to other group members. Together these studies demonstrate that group problem solving is governed jointly by qualities of the task and qualities of the group members. Copyright © 2006 John Wiley & Sons, Ltd.     

Sense of control predicts depressive and anxious symptoms across the transition to parenthood.

In this study, the authors examined the relationship between sense of control and depressive and anxious symptoms for mothers and fathers during the 1st year of parenthood. Participants were 153 dual-earner, working-class couples who were recruited during the 3rd trimester of pregnancy at prenatal education courses. Data were collected 1 month antenatally and 1, 4, 6, and 12 months postnatally. Sense of control was decomposed into 2 distinct parts: an enduring component and a malleable component that changes with context. Consistent with a cognitive theory of emotional problems, results demonstrated that a sense of control served a protective function for mental health outcomes. A higher sense of enduring control predicted lower levels of psychological distress for new parents, and increases in control over time predicted decreases in depression and anxiety. Findings hold implications for interventions with expectant parents, such as expanding prenatal education courses to include strategies for enhancing and maintaining a sense of personal control.     

Meadow voles, <Emphasis Type="Italic">Microtus pennsylvanicus</Emphasis>, have the capacity to recall the “what”, “where”, and “when” of a single past event

Some non-human animals may possess the ability to recall the “what”, “where”, and “when” of a single past event. We tested the hypothesis that male meadow voles posses the capacity to recall the “what”, “where”, and “when” of a single past event associated with mate selection in two experiments. Briefly, male voles were allowed to explore an apparatus that contained two chambers. One chamber contained a day-20 pregnant female (24 h prepartum). The other chamber contained a sexually mature female that was neither pregnant nor lactating (REF female). Twenty-four hour after the exposure, the males were placed in the same apparatus, which was empty and clean. At this time, the pregnant female would have entered postpartum estrus (PPE), a period of heightened sexual receptivity. Males initially chose and spent significantly more time investigating the chamber that originally housed the pregnant female (now a PPE female) than the chamber that originally housed the REF female. Male voles also explored an apparatus containing a chamber with a PPE female and one chamber containing a REF female. Twenty-four hour later, males were placed into an empty and clean apparatus. The males did not display an initial choice and they spent similar amounts of time investigating the chamber that originally housed the PPE female (now a lactating female) and the chamber that originally housed the REF female. The results of these and additional experiments suggest that male voles may have the capacity to recall the “what”, “where”, and “when” of a single past event, which may allow males to remember the location of females who would currently be in heightened states of sexual receptivity.     

Feminist Slants on Nature and Health

Ecological feminism (or ecofeminism) and feminist bioethics seem to have much in common. They share certain methodological and epistemological concerns, offer similar challenges to traditional philosophy, and take up a number of the same practical issues. The two disciplines have thus far had little or no direct interaction; this is one attempt to begin some conversation and perhaps stimulate some cross-pollination of ideas. The email dialogue engaged an active ecofeminist scholar, Karen Warren, and an active feminist bioethicist, Hilde Nelson, in an exchange of ideas. Jessica Pierce, whose research cuts between environmental philosophy and bioethics, served as moderator.     

Dishonesty in the Name of Equity

ABSTRACT— Under what conditions do people act dishonestly to help or hurt others? We addressed this question by examining the influence of a previously overlooked factor—the beneficiary or victim of dishonest acts. In two experiments, we randomly paired participants and manipulated their wealth levels through an initial lottery. We then observed how inequity between partners influenced the likelihood of one dishonestly helping or hurting the other, while varying the financial incentives for dishonest behavior. The results show that financial self-interest cannot fully explain people's tendency to dishonestly help or hurt others. Rather, such dishonesty is influenced by emotional reactions to wealth-based inequity, even when the dishonesty bears a personal financial cost. Envy evoked by negative inequity led to hurting behavior, whereas guilt induced by positive inequity motivated helping behavior. Finally, inequity between the partner and third parties triggered dishonest helping through empathy with the partner.     

The conceptual centrality of causal cycles

How do causal cycles affect judgments of conceptual centrality? Generally, a feature is central to a concept to the extent that other features in the concept depend on it, thereby rendering it immutable from the concept (Sloman, Love, &; Ahn, 1998). Previous research on conceptual centrality has focused primarily on features involved in four major types of dependency structures: simple cause-effect relations, causal chains, common-cause structures, and common-effect structures. Causal cycles are a fifth type of dependency structure commonly reported in people’s real-life concepts, yet to date, they have been relatively ignored in research on conceptual centrality. The results of six experiments suggest that previously held assumptions about the conceptual representation of cycles are incorrect. We discuss the implications of these findings for our understanding of theory-based concepts.
