Math anxiety: who has it, why it develops, and how to guard against it

Basic math skills are important for success in school and everyday life. Yet many people experience apprehension and fear when dealing with numerical information, termed math anxiety. Recently, researchers have started to probe the antecedents of math anxiety, revealing some surprising insights into its onset, risk factors, and remediation.     

Grassroots spirituality: What it is,why it is here,where it is going,by Robert K. Forman

Among Asian Americans, particularly within immigrant communities, religious leaders are respected and sought out for support and guidance. There is a need to examine how religious leaders, especially within non-Christian faiths, identify persons and ascribe meaning and attributions to mental health concerns. The aim of this paper was to address this knowledge gap by exploring the perceptions of five Vietnamese American Buddhist leaders in regards to mental illness. Using qualitative analytic techniques we identified appearance, behaviours, and cognitive impairments that leaders interpreted as indicators of a mental health condition. Religious leaders cited messy and overly adorned outer appearance, aggressive and violent behaviours, and abnormal cognitive functioning as indicative of mental health problems. They attributed mental illness to a variety of causes: daily stressors, mind-body imbalance, karma, virtuous deeds, and spiritual possession. Findings inform strategies for faith-based initiatives and mental health service delivery to religiously affiliated Asian Americans.     

Feeling the burn: When it looks like it hurts,and belongs to me,it really does hurt more

We examined changes in pain sensitivity in the rubber hand illusion (RHI). Experiment 1 investigated changes in pain tolerance immediately after a “healthy” and “wounded” RHI when immersing the hand in a cold pressor ice bath. There was 19% increased pain tolerance and increased perception detection threshold after the healthy RHI, but 11% reduction after the wounded RHI. Experiment 2 examined pain experience during the wounded RHI with capsaicin-induced hyperalgesia. Pain intensity and unpleasantness was higher on the illusion arm during the synchronous RHI, compared with asynchronous trials. There was no change in pain experience on the control arm, and both arms had similar pain sensitivity after the experiment. Our results highlight the impact of embodying a substitute limb on pain, with increased tolerance and reduced tactile sensitivity when the fake limb is healthy and apparently pain-free, but increased pain sensitivity when the self-attributed limb appears to be wounded.     

Sterba on Affirmative Action,or, it Never was the bus,it was Us!

Professor Sterba argues for two interesting and provocative positions regarding affirmative action. First, affirmative action programs are still needed to ensure diversity in educational institutions of higher learning. Secondly, the proponents and opponents of affirmative action are not as far apart as they seem to think. To this end, he proposes a position that would give weight to race as a category for affirmative action that can withstand the challenges of affirmative action opponents while giving the needed support for affirmative action proponents. It is his contention that both sides can support arguments for diversity affirmative action. This paper raises concerns about the ability of arguments for racial diversity to resolve or bring together opponents and proponents of affirmative action. It is argued that the negative social climate, regarding the social and intellectual merits of black Americans, works against the acceptance of affirmative action programs. In sum, it is argued that Professor Sterba’s position continues to put the social onus of changing racial attitudes on blacks with little or no effort on the part of whites other than allowing blacks admittance to formerly segregated educational institutions to interact with white students.     

A social-psychological perspective on tacit coordination: How it works,when it works, (and when it does not)

We present a programmatic line of experimental studies which focus on the how and when of tacit coordination (i.e., the phenomenon that people can successfully coordinate their decisions without communication). We investigated this phenomenon using different types of economic games (i.e., social dilemmas as well as coordination games). Our studies broadly cover three themes: (a) fairness as a coordination rule, (b) uncertainty and common understanding, (c) social information as a cue. By focusing on these themes we have obtained several new insights on the prerequisites and boundary conditions of tacit coordination. We conclude that tacit coordination is often facilitated by mutual adherence to social norms (e.g., fairness rules, rules of deference, etcetera), but that in order to employ such norms people need sufficient environmental and/or social information.     

Making it without losing it: Type A, achievement motivation, and scientific attainment revisited

In a study by Matthews, Helmreich, Beane, and Lucker (1980), responses by academic psychologists to the Jenkins Activity Survey for Health Prediction (JAS), a measure of the Type A construct, were found to be significantly, positively correlated with two measures of attainment, citations by others to published work and number of publications. In the present study, JAS responses from the Matthews et al. sample were subjected to a factor analysis with oblique rotation and two new subscales were developed on the basis of this analysis. The first, Achievement Strivings (AS) was found to be significantly correlated with both the publication and citation measures. The second scale, Impatience and Irritability (I/I), was uncorrelated with the achievement criteria. Data from other samples indicate that I/I is related to a number of health symptoms. The results suggest that the current formulation of the Type A construct may contain two components, one associated with positive achievement and the other with poor health.     

Data, model, conclusion, doing it again

This paper explores the robustness of conclusions from a statistical model against variations in model choice (rather than variations in random sampling and random assignment to treatments, which are the usual variations covered by inferential statistics). After the problem formulation in section 1, section 2 presents an example from Box and Tiao in which variation in parent distribution is modeled for a one sample location problem. An adaptive Bayesian procedure permits to use a weighted mixture of parent distributions rather than choosing just one, such as a normal or a uniform distribution.In section 3 similar considerations are applied to an event history model for the influence of education and gender on age at first marriage, but here the conclusions are hardly influenced by the choice of the duration distribution. In section 4 a brief discussion of model choice in factor analysis and structural equation models is followed by a more elaborate treatment of the choice of integer valued slopes for item response functions in the OPLM model which is an extension of the Rasch model. A modest simulation study suggests that Adaptive Bayesian Modeling with a mixture of sets of slopes works better than fixing one set of postulated slopes.The paper concludes with some remarks on the roles and sources of prior distributions followed by a short epilogue which argues that simultaneous consideration of a class of models for the same data is sometimes superior to exclusively analyzing the data under one specific model chosen from such a class.This article is based on the Presidential Address Ivo W.

Try it, you'll like it: the influence of expectation, consumption, and revelation on preferences for beer

Patrons of a pub evaluated regular beer and "MIT brew" (regular beer plus a few drops of balsamic vinegar) in one of three conditions. One group tasted the samples blind (the secret ingredient was never disclosed). A second group was informed of the contents before tasting. A third group learned of the secret ingredient immediately after tasting, but prior to indicating their preference. Not surprisingly, preference for the MIT brew was higher in the blind condition than in either of the two disclosure conditions. However, the timing of the information mattered substantially. Disclosure of the secret ingredient significantly reduced preference only when the disclosure preceded tasting, suggesting that disclosure affected preferences by influencing the experience itself, rather than by acting as an independent negative input or by modifying retrospective interpretation of the experience.     

Attend to it now or lose it forever: selective attention,metacontrast masking,and object substitution

Metacontrast masking occurs when the visibility of a brief target stimulus is decreased by the subsequent appearance of another nearby visual stimulus. Early explanations of the phenomenon involved low-level mechanisms, but subsequent studies have suggested a role for selective attention. The results of three experiments presented here extend previous findings to the metacontrast paradigm. It is shown that the strength of metacontrast masking increases with the number of distractor items in a display, decreases when the target location is validly but not invalidly precued, and is eliminated when search for the target is efficient (pop-out search) but not when search is inefficient (serial search). A connection between metacontrast masking and object substitution masking is considered.     

Education,In Spite of it All

This special issue of Studies in Philosophy and Education neither rejects, nor offers outright alternatives to the dominant contemporary model of education, but instead explores its margins and the possibilities they might offer for administrators, teachers and students within institutions and broader social contexts. The intention of the editors and contributors has been to tweak the focus from a critique of an oppressive system to a mapping of that system and the opportunities that exist within it–or on its margins–in spite of itself.     

"But still, it moves"

A striking example of our sensitivity to dynamic information is our ability to infer motion from still images depicted in paintings, photographs or cartoons. What are the neural mechanisms that mediate this implied motion perception? In a recent paper, Krekelberg et al. demonstrate that form cues that imply motion are integrated with real motion information, and influence perception in both humans and monkeys and the neural processing in prototypical motion areas of the monkey brain.     

If I imagine it,then it happened: The Implicit Truth Value of imaginary representations

Imagination sometimes leads people to behave, feel, and think as though imagined events were real even when they know they were not. In this paper, we suggest that some understanding of these phenomena can be achieved by differentiating between Implicit Truth Value (ITV), a spontaneous truth evaluation, and Explicit Truth Value (ETV), a self-reported truth judgment. In three experiments, we measure ITV using the autobiographical Implicit Association Test (Sartori, Agosta, Zogmaister, Ferrara, & Castiello, 2008), which has been used to assess which of two autobiographical events is true. Our findings demonstrate that imagining an event, like experiencing an event, increases its ITV, even when people explicitly acknowledge the imagined event as false (Experiments 1a and 1b). Furthermore, we show that imagined representations generated from a first-person perspective have higher ITV than imagined representations generated from a third-person perspective (Experiment 2). Our findings suggest that implicit and explicit measures of truth differ in their sensitivity to properties underlying truth judgment. We discuss the contribution of characterizing events according to both ITV and ETV to the understanding of various psychological phenomena, such as lying and self-deception.     

Professional support for adolescent mothers: Who gives it,how adolescent mothers evaluate it,what they would prefer

Forty-two adolescent mothers with 2-year-old children were questioned about their sources of social support, their satisfaction with that support, and their views about including members of their informal support network in the receipt of professional services. The results indicated that 74% of the mothers received parenting advice from some professional source, as well as from their informal support network, and that most were satisfied with their professional contacts. Nonetheless, 75% of the mothers indicated that they would like additional parenting advice from parenting classes, organized neighborhood groups, or from visiting public health nurses or other child development specialists. Ninety percent of the mothers thought it would be helpful to have members of their informal support network participate with them in the receipt of professional services, and 81% thought these individuals would be willing to do so. The implications of these findings for both future research and the design and implementation of programs directed toward adolescent parents and their children are discussed.     

Sharing economy promotes morality,not impedes it

Sharing economy (SE) is a rapidly growing economic model which has brought people efficiency and convenience; however, it also provides users the opportunity to misbehave, which has raised public concerns about the moral crisis that it might cause. We examined the effect of SE on individuals’ unethical behaviors through four studies. We found consistently that making people believe that they were using shared goods (Study 1) or priming them with abstract SE mindsets (Studies 2–4) reduced, not facilitated, their subsequent cheating on task performances to gain monetary rewards. Moreover, the effect of SE on cheating was mediated by a sense of connecting to others (Study 4). Thinking of using SE enhanced individuals’ interpersonal closeness, which in turn led to less unethical behavior. However, correlational analyses in Studies 3 and 4 showed that people who cheated more in studies in the laboratory also reported using SE more frequently in real life. Implications of these findings are discussed.
