An investigation of preschoolers' misattributions of the properties of two‐dimensional images: understanding the relationship between a symbol and its referent

Previous studies have found that preschoolers are confused about the relationship between two‐dimensional (2D) symbols and their referents. Preschoolers report that 2D images (e.g. televised images and photographs) share some of the characteristics of the objects they are representing. A novel Comparison Task was created to test what might account for these misattributions of the properties of 2D images. Three‐and‐a‐half‐ and four‐and‐a‐half‐year olds made comparisons between items presented in two of three formats simultaneously, i.e. as a real object and as an object appearing on television (TV), as a real object and as a photo of that object, or as an object appearing on TV and in a photo. Presenting the televised object or the photo of the object along with the real object aided performance; children indicated that televised objects and photos of objects no longer shared the properties of the real objects. Children also performed better when presented with two 2D images of the same object (the photo of the object and the televised image of the object). Although dual‐representation might account for these misattributions of the properties of 2D images, because children also performed better when two 2D images of the same object were present, other possibilities such as children using pictures as communicative devices and disregarding the pragmatics of the task should be explored.

Why do children lack the flexibility to innovate tools?

Despite being proficient tool users, young children have surprising difficulty in innovating tools (making novel tools to solve problems). Two experiments found that 4- to 7-year-olds had difficulty on two tool innovation problems and explored reasons for this inflexibility. Experiment 1 (N = 51) showed that children’s performance was unaffected by the need to switch away from previously correct strategies. Experiment 2 (N = 92) suggested that children’s difficulty could not easily be explained by task pragmatics or permission issues. Both experiments found evidence that some children perseverated on a single incorrect strategy, but such perseveration was insufficient to explain children’s tendency not to innovate tools. We suggest that children’s difficulty lies not with switching, task pragmatics, or behavioral perseveration but rather with solving the fundamentally “ill-structured” nature of tool innovation problems.     

What motivates lay third parties to take sides in a conflict? Examining the relationships between the Big Five personality traits and side‐taking motives

Taking sides is one of the reactions available to third parties in handling a dispute. From the perspective of individual differences, this study was aimed at identifying lay third parties' motives for side taking and exploring their relations with the Big Five personality traits. We tested our assumptions using three samples: A Dutch student sample (n = 111), a Dutch employee sample (n = 101) and a Chinese student sample (n = 124). The findings revealed four types of side‐taking motives: Moral, relational, reward‐approaching and sanction‐avoiding motives. The results also showed that individuals' personality traits were relevant to the four types of side‐taking motives: Agreeableness was associated with the relational motive for side taking, and intellectual autonomy was associated with the reward‐approaching motive, the sanction‐avoiding motive and the relational motive for side taking. Implications and explanations of these findings are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

儿童特质推理与情绪和效价线索理解的关系

本研究从情绪、效价两个角度探讨儿童特质理解与线索理解的关系。372名4、5、7岁儿童完成了贴标签和行为预测两类特质推理任务。实验一显示,所有年龄段儿童都能完成对情绪性特质害羞和胆小的推理,且特质和行为评定与情绪评定呈显著正相关;实验二显示,所有年龄段均能完成双重性质特质助人为乐和自私的推理,特质和行为评定与效价、情绪评定均呈显著正相关,回归分析则只有效价评定进入方程。结果说明,儿童完成情绪性特质推理任务时与情绪理解能力关系密切,而对双重性质特质推理时更多的与效价理解能力有关。     

Superaddressee or Who Will Succeed a Mentor?

This philosophical essay is inspired by a four-year pedagogical relationship that continues in its altered form today. The main focus of this piece is the transformation of a mentor as an immediate addressee into mentor as a superaddressee, an influential third listener who oversees observable dialogues. I explore the mutual responsibilities of a student and a mentor in order to uncover the elements in the pedagogical chemistry responsible for the transformation of an addressee into a superaddressee. Confirmation (a perfect form of understanding) of a student’s intellectual and moral uniqueness, incarnation of a particular value deemed desirable by a student, and education of a student into the dialogic ways of being on his or her own are the necessary ingredients of the process of becoming a superaddressee. Initially a mentor engages in the pedagogy of understanding whose ideal outcome is confirmation of a student’s intellectual and moral makeup. After the dialogue is over, a mentor often moves into the domain of inner speech from where he or she continues to offer perfect understanding, especially in the absence of such understanding from an immediate addressee. Two types of superaddressees are identified and their relationship with the invoking consciousness is explored. I conclude that becoming a superaddressee is the most generous pedagogical contribution to a student’s future: a mentor thus makes his or her voice available to a student’s inner dialogue, often without receiving anything in return. Mikhail Bakhtin is highly influential in my writing. “Superaddressee” or “a third listener” is one of his coinages. The term is treated in “The Problem of the Text” as part of the collection “Speech genres and other late essays” (1986), alluded to in Voloshinov’s (1976) “Discourse in Life and Discourse in Art” and expanded upon in Frank Farmer’s (2001) “Saying and Silence.”     

Lay counselors: Thoughts on the crossing of ecological frameworks and the use of lay counselors in the scale up of early infant mental health interventions

The recent call for the scale-up of evidence-based early childhood development interventions, in lower and middle-income countries and for minority groups in high-income countries, has seen numerous suggestions to train greater numbers of lay mental health workers to fulfill these functions. While studies have found that concepts from developed country settings, such as attachment, parental sensitivity, and containment, find purchase and relevance within developing settings, the management of contextual and cultural factors and the tensions of cultural interfacing in the rollout of these programs in developing country settings require consideration. Drawing on the experiences of two successful South African mother–infant home-visiting programs as examples, this article discusses some of the challenges in provision of attachment-based infant mental health programs and highlights the need for careful consideration of a number of factors pertaining to the recruitment, supervision, and management of lay mental health workers before large-scale rollout is conducted.     

东西方文化的人性观差异及其对道德认知的影响

人性观,即认为人性究竟是本善的还是本恶的,不仅是哲学思辨的焦点,也是日常生活中形成的一种常人理论(lay theory)。对于东西方文化传统的检视表明,西方文化占主导地位的是性恶论人性观,东方文化占主导地位的则是性善论人性观。研究通过实证数据支持了这一结论,发现中国被试相对于美国被试,对于人性的主观评定更倾向于性善的一端(研究1)。这种人性观差异导致中国被试在道德方面,尤其是规范性道德(行善)方面,对人提出了更高的要求(研究1),并且这种因果关系得到了启动实验的支持(研究2)。这些研究结果有助于人们更好地理解文化如何塑造了人们对于人性和道德的看法。     

I knew you'd understand: How gendered expectations of understanding affect stress

An experimental design was used to examine the effects of interviewer gender and (mis)understanding on physiological stress (i.e., cortisol). A total of 103 undergraduate students wrote about a recent social conflict and then discussed that conflict with either a male or a female interviewer. During these discussions, the interviewer displayed verbal and nonverbal cues of (mis)understanding toward the participants. Participants' cortisol was assessed four times throughout the study. Results from a 2 × 2 × 4 mixed‐model analysis of variance demonstrated an interaction between the gender of the interviewer, understanding condition, and time such that cortisol decreased the most over time when the interviewer used cues of understanding that matched stereotypical expectations for the interviewers' gender (i.e., when women were understanding and men were misunderstanding).     

Taking spiritual experiences seriously in the religious education classroom: a transrational approach

ABSTRACT

Spiritual experiences are common across religious and non-religious faiths, but schoolchildren are often afraid to share these because they fear ridicule from peers who are convinced religion is irrational. The need to speak about spirituality in religious education is increasingly recognised. Signposts suggests that intercultural understanding implies recognising religious students’ perception of reality and helping others understand it. Religious education in Norway now includes exploration of existential questions as a core element, and in England, making sense of religious, spiritual and mystical experiences has been suggested as a big idea. In this paper, we discuss how the dualistic paradigm of modern science makes it difficult to take spirituality seriously as lived experience and empirical phenomenon. Instead we suggest a transrational approach to explore our multidimensional reality in an intercultural dialogue where insiders and outsiders learn from each other. We also explore examples of transrational research on spiritual phenomena.
