类比推理的发展理论评析

类比在认知科学领域具有特殊的地位,儿童类比推理能力的发展是其认知发展的重要成分之一。本文系统介绍了类比推理发展研究中的几个重要理论,即能力限制说、知识经验说和关系转换说等。在此基础上,作者进一步对类比推理发展研究中涉及的几个焦点问题,如类比推理出现的最早年龄,类比推理发展的影响因素及类比推理的发展趋势等进行了综合评析。     

Minimizing the influence of recoding in the Implicit Association Test: The Recoding-Free Implicit Association Test (IAT-RF)

Recoding processes can influence the Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998) in a way that impedes an unequivocal interpretation of the resulting compatibility effects. We present a modified version of the IAT that aims to eliminate recoding, the IAT-RF (short for “IAT–recoding free”). In the IAT-RF, compatible and incompatible assignments of categories to responses switch randomly between trials within a single experimental block. Abandoning an extended sequence of consistent category–response mappings undermines recoding processes in the IAT-RF. Two experiments reveal that the IAT-RF is capable of assessing compatibility effects between the nominally defined categories of the task and effectively prevents recoding. By enforcing a processing of the stimuli in terms of their task-relevant category membership, the IAT-RF eliminates the confounding of compatibility effects with task switch costs and becomes immune against biased selections of stimuli.     

Conflict in object affordance revealed by grip force

Viewing objects can result in automatic, partial activation of motor plans associated with them—“object affordance”. Here, we recorded grip force simultaneously from both hands in an object affordance task to investigate the effects of conflict between coactivated responses. Participants classified pictures of objects by squeezing force transducers with their left or right hand. Responses were faster on trials where the object afforded an action with the same hand that was required to make the response (congruent trials) compared to the opposite hand (incongruent trials). In addition, conflict between coactivated responses was reduced if it was experienced on the preceding trial, just like Gratton adaptation effects reported in “conflict” tasks (e.g., Eriksen flanker). This finding suggests that object affordance demonstrates conflict effects similar to those shown in other stimulus–response mapping tasks and thus could be integrated into the wider conceptual framework on overlearnt stimulus–response associations. Corrected erroneous responses occurred more frequently when there was conflict between the afforded response and the response required by the task, providing direct evidence that viewing an object activates motor plans appropriate for interacting with that object. Recording continuous grip force, as here, provides a sensitive way to measure coactivated responses in affordance tasks.     

The emergence of words: attentional learning in form and meaning

Children improve at word learning during the 2nd year of life—sometimes dramatically. This fact has suggested a change in mechanism, from associative learning to a more referential form of learning. This article presents an associative exemplar-based model that accounts for the improvement without a change in mechanism. It provides a unified account of children's growing abilities to (a) learn a new word given only 1 or a few training trials ("fast mapping"); (b) acquire words that differ only slightly in phonological form; (c) generalize word meanings preferentially along particular dimensions, such as object shape (the "shape bias"); and (d) learn 2nd labels for already-named objects, despite a persisting resistance to doing so ("mutual exclusivity"). The model explains these improvements in terms of increased attention to relevant aspects of form and meaning, which reduces memory interference. The interaction of associations and reference in word learning is discussed.     

类比迁移发生机制的研究

本研究包含两个实验,探讨类比迁移发生的机制。实验一主要探索类比迁移中的图式归纳是一种自动加工还是控制加工。实验二主要探索类比迁移中的图式归纳是保留性的还是排除性的。本实验结果表明,类比迁移中的图式归纳主要是控制加工,是一种保留性的归纳。     

Career mapping for international students: A critical-constructivist approach

Despite rapidly increasing presence of international students seeking career guidance and opportunities in the United States, existing counseling literature offers limited perspectives on how counselors can support this community using strengths-based and culturally responsive approaches. Addressing this long-standing gap, we offer this conceptual scholarship discussing career mapping as a dialogical and critical-constructivist strategy for career counselors to help international students understand their life story, strengths, and barriers in the context of career development, and plan their actions accordingly. Implications for practice are also offered.     

Not all is forgotten: Children's associative matrices for features of a word learning episode

Word learning studies traditionally examine the narrow link between words and objects, indifferent to the rich contextual information surrounding objects. This research examined whether children attend to this contextual information and construct an associative matrix of the words, objects, people, and environmental context during word learning. In Experiment 1, preschool-aged children (age: 3;2–5;11 years) were presented with novel words and objects in an animated storybook. Results revealed that children constructed associations beyond words and objects. Specifically, children attended to and had the strongest associations for features of the environmental context but failed to learn word-object associations. Experiment 2 demonstrated that children (age: 3;0–5;8 years) leveraged strong associations for the person and environmental context to support word-object mapping. This work demonstrates that children are especially sensitive to the word learning context and use associative matrices to support word mapping. Indeed, this research suggests associative matrices of the environment may be foundational for children's vocabulary development.     

Psychotherapists' efforts to increase awareness of social privilege

Understanding the role of privilege in systemic oppression positions psychotherapists to engage in culturally oriented practice. Twenty-five practising psychotherapists were asked: ‘How can psychotherapists increase their awareness of social privilege?’ Participants sorted 68 unique responses into six concepts. The concepts included: make yourself uncomfortable; embrace humility; learn from the community; involvement in social action; seek critical knowledge; and find like-minded others in the profession. Recommendations for student training are offered.     

道德概念垂直空间隐喻理解中的映射:双向性及不平衡性

通过4个实验考察道德概念垂直空间隐喻理解中的映射机制和特征。实验1采用空间Stroop范式,发现被试判断完道德词后,对判断随后呈现在屏幕上方或下方字母的反应时的差异不显著,没有发现词汇类型对空间位置的影响。实验2采用有意识迫选法,要求被试出声读出屏幕中央的道德词后,对屏幕上方或下方的希腊语非词进行二择一迫选,发现被试读出道德词后倾向于选择屏幕上方的非词,读出不道德词后倾向于选择屏幕下方的非词。实验3仍采用Stroop范式,发现被试做出空间"上"的判断后,对随后道德词的词义判断反应时显著快于不道德词,做出空间"下"的判断后,对不道德词的反应时显著快于道德词。实验4探讨空间位置是否会对判断人物的道德性产生影响,结果发现被试倾向于认为屏幕上方的人物是道德的,而屏幕下方的人物是不道德的。4个实验的结果表明,在道德概念垂直空间隐喻的理解中,映射的方式是灵活的、双向的,既可以由始源域向目标域映射,也可以由目标域向始源域映射,但两个方向上的映射力量是不平衡的。     

时间的多维度空间表征:分离的起源与激活机制

近期研究发现时间可以分别在三个空间维度(左右、前后和上下)进行表征, 但不同维度心理时间线的起源和激活机制尚存争议。最新证据表明, 左右维度时间线主要起源于阅读/书写习惯所伴随的感觉运动经验, 其激活可能是一种低水平的感觉运动机制; 前后和上下维度时间线主要起源于语言中的空间隐喻, 其激活可能是一种高水平的语义机制。未来研究应更关注心理时间线的起源多样性、先天基础、神经机制以及时间线和数字线的类比。
