No blank slates: Pre-existing schemas about pharmaceuticals predict memory for side effects

Objectives: Attribution of symptoms as medication side effects is informed by pre-existing beliefs about medicines and perceptions of personal sensitivity to their effects (pharmaceutical schemas). We tested whether (1) pharmaceutical schemas were associated with memory (recall/recognition) for side effect information (2) memory explained the attribution of a common unrelated symptom as a side effect.

Design: In this analogue study participants saw the patient leaflet of a fictitious asthma drug listing eight side effects.

Main outcome measures: We measured recall and recognition memory for side effects and used a vignette to test whether participants attributed an unlisted common symptom (headache) as a side effect.

Results: Participants who perceived pharmaceuticals as more harmful in general recalled fewer side effects correctly (r_{Correct Recall} = ?.273), were less able to differentiate between listed and unlisted side effects (r_{Recognition Sensitivity} = ?.256) and were more likely to attribute the unlisted headache symptom as a side effect (r_{side effect attribution} = .381, ps < .01). The effect of harm beliefs on side effect attribution was partially mediated by correct recall of side effects.

Conclusion: Pharmaceutical schemas are associated with memory for side effect information. Memory may explain part of the association between pharmaceutical schemas and the attribution of unrelated symptoms as side effects.     

Children's understanding of mental states as causes of emotions

Theory of mind studies of emotion usually focus on children's ability to predict other people's feelings. This study examined children's spontaneous references to mental states in explaining others' emotions. Children (4‐, 6‐ and 10‐year‐olds, n = 122) were told stories and asked to explain both typical and atypical emotional reactions of characters. Because atypical emotional reactions are unexpected, we hypothesized that children would be more likely to refer to mental states, such as desires and beliefs, in explaining them than when explaining typical emotions. From the development of lay theories of emotion, derived the prediction that older children would refer more often to mental states than younger children. The developmental shift from a desire‐psychology to a belief‐psychology led to the expectation that references to desires would increase at an earlier age than references to beliefs. Our findings confirmed these expectations only partly, because the nature of the emotion (happiness, anger, sadness or fear) interacted with these factors. Whereas anger, happiness and sadness mainly evoked desire references, fear evoked more belief references, even in 4‐year‐olds. The fact that other factors besides age can also play an influential role in children's mental state reasoning is discussed. Copyright © 2005 John Wiley & Sons, Ltd.     

Children's beliefs about the continuity of aggression

Elementary school students (N = 139) read vignettes describing aggressive peers and rated the extent to which they believed the peers' aggression would continue over time and in different contexts. Children also rated their social and moral acceptance of aggression, and how difficult it would be to help the vignette characters desist from aggression. Teachers rated participants' aggressive and prosocial behaviors. Results indicated that aggression is generally viewed as continuous across time and context, and likely to produce little acceptance. Beliefs about continuity were positively associated with perceived difficulty of changing aggression and negatively associated with social acceptance. Gender moderated the association between continuity beliefs and moral acceptance. Teacher‐rated behavior was associated with social perceptions. Findings are discussed with regard to their implications for future research as well as their potential application to the design of interventions for youth aggression. Aggress.

关于自身记忆信念的年龄差异

记忆老化信念是元记忆研究的一个重要研究领域。本研究测量了94名老年人,38名年轻人记忆老化信念中关于自身记忆信念。结果发现,各年龄组间在对特定情境记忆能力信念上有差异,60～64岁、65～69岁年龄组被试对特定情境记忆能力评价最高,而70岁以上老年人与年轻组被试对特定情境上记忆能力评分无差异;年轻人对记忆的控制感要低于各组老年人;研究并没有发现被试在一般记忆能力信念上的年龄差异。     

《太平广记》中的蛇信仰研究

根据《太平广记》蛇类故事和龙类故事的记载,论述汉魏至隋唐时期民间对蛇的信仰情况,指出当时的蛇信仰正处于与龙信仰的混淆与渐渐析离时期。一方面蛇具有与龙相同的神圣性,另一方面蛇也开始遭到人们的嫌恶。龙蛇信仰的最终分离,使他们在民间信仰中朝着两个截然不同的方向发展下去。     

家庭文化资本对幼儿数学学习的影响

本研究对来自上海市的590个中、大班幼儿家庭进行问卷调查,旨在了解家庭文化资本对幼儿数学学习的影响。结果表明：作为家庭客体化文化资本的家庭文化环境和作为家庭身体化文化资本的幼儿家长数学教导信念对幼儿的家庭数学学习经验有直接的影响作用;作为家庭制度化文化资本的家庭教育背景则通过家庭文化环境和幼儿家长的数学教导信念对幼儿家庭数学学习经验有间接的影响作用。     

How to Cook Rice: A Review of Ingredients for Teaching anti‐Prejudice

There is a pressing need to address prejudice, racism, and discrimination against marginalised groups in Australia. This involves change from the structural to the individual level. In this article, we discuss the merits of individual anti‐prejudice mechanisms within the Australian context. First, we expand on nine mechanisms described in a previous paper and then review five new mechanisms. We conclude that while some mechanisms are likely to be useful regardless of location, others need to be tailored to the local context. We also conclude that effective interventions need to utilise multiple mechanisms. It is hoped that the synthesis of the different mechanisms provided here will assist anti‐prejudice researchers, practitioners, and policymakers striving to improve relations among different groups in our society.     

How beliefs influence the relative magnitude of pleasure and pain

Loss aversion is an economic assumption about utility—people value giving up a good more than they value getting it. It also has hedonic meaning—the pain of a loss is greater in magnitude than the pleasure of a comparable gain. But value and pleasure are not necessarily identical. We test the hedonic interpretation of loss aversion in experimental markets. With hedonic forecasts, sellers imagine the pain of losing their endowment, and buyers imagine the pleasure of being endowed. With hedonic experiences, sellers rate the pleasure of having the endowment, and buyers rate the pain of being without it. Contrary to loss aversion, predicted pleasure is greater in magnitude than predicted pain, and experienced pleasure surpasses experienced pain. We show that the relative magnitude of pleasure and pain depends on beliefs about the likelihood of outcomes, as well as utilities. Surprise makes gains more pleasurable and losses more painful. With surprising gains and expected losses, pleasure can surpass pain. But when gains and losses are equally likely (or losses are surprising and gains are expected), the opposite pattern can occur. Finally, within‐group and between‐group prices are significantly correlated with hedonic experiences. Sellers who feel better with their endowments assign higher selling prices, and buyers who feel worse about the absence of endowment assign higher buying prices. Despite the fact that hedonic experiences deviate from loss aversion, these emotions predict the endowment effect. Copyright © 2009 John Wiley & Sons, Ltd.     

Intent to harm or injure? Gender and the expression of anger

Gender differences in aggressive behaviour but not in anger suggest that women may express anger through behaviours that lack intent to harm or injure. Angry behaviours (injurious and noninjurious) were rated in terms of their likelihood of use when angry (N=888). Confirmatory factor analysis revealed a direct aggression factor and two further scales: explosive acts (e.g. throwing objects when alone) and defusing acts (e.g. talking to a third party). Men exceeded women on direct aggression and explosive acts, whereas women exceeded men on defusing acts. Expressive beliefs about aggression (as a loss of self-control) were higher among women and strongly associated with use of defusing acts and the avoidance of direct aggression. Instrumental beliefs about aggression (as a means of control over others) were higher among men and showed the opposite pattern of associations. We highlight the need for further work on actors' intention in relation to angry behaviours and the impact of context on these intentions.
