How to cook a SNARC: Number placement in text rapidly changes spatial–numerical associations

Most theoreticians believe that reading habits explain why Western adults associate small numbers with left space and large numbers with right space (the SNARC effect). We challenge this belief by documenting, in both English and Hebrew, that SNARC changes during reading: small and large numbers in our texts appeared near the left or right ends of the lines, positioned either spatially congruent or incongruent with reading habits. In English, the congruent group showed reliable SNARC before and after reading and the incongruent group’s SNARC was significantly reduced. In Hebrew the incongruent reading condition even induced a reverse SNARC. These results show that SNARC is a fleeting aspect of number representation that captures multiple spatial associations.     

Doing business: an obscure notion of the ethics of public associations in ordinary Chinese

Along with the notion of being a person (zero run 做人), the notion of doing business (zuo shi 做事) in ordinary Chinese is basically an over-all notion of the norms in the practical and associative activities, carrying typically obscure meanings on practice and association affairs in some external world. Ordinary Chinese not only distinguishes these two notions but also defines a dictionary order of them, with the affairs of the internal world prior to those of the external. The fact that the notion of doing business refers to business (shi 事) rather than person (ren 人) makes this order clear at a deeper level. It shows that this notion regards the practical affairs of the external world less important to the person itself than those of the internal. Except for these qualities, the notion of doing business holds some normative meanings, although contains no definite rules. These meanings indirectly relate to the notion of person that people form in their private associations and emerge as some mixture with a tactical attitude out of the need of earning a life. The notion of person gives birth to some obscure requirements, for instance, the requirement of ‘doing business in accordance with your conscience’ and that of ‘doing business seriously’. The core world of family is marginalized in the public transition of associations. There are reasons to anticipate that in this process the notion of doing business will undergo more radical changes than that of being a person. __________ Translated from Zhexue Yanjiu 哲学研究 (Philosophical Studies), 2005 (7)     

A new spin on losses looming larger than gains: asymmetric implicit associations from slot machine experience

Kahneman and Tversky's prospect theory states, among other things, that losses loom larger than gains. As much research as this simple idea has generated, key questions remain. How fundamental is the losses‐looming‐larger effect: will it emerge under more minimal circumstances than previously tested and will it manifest in implicit associations? And how does the actual experience of predominant losses or gains affect the losses‐looming‐larger effect? In two experiments employing non‐traditional methods, participants experienced slot machine spins in which symbols were paired with gain, loss, and neutral outcomes. After experiencing these pairings, participants took Implicit Association Tests (IATs). In Experiment 1, implicit associations formed by the minimal experience of the slot machine were lopsided: negative associations with the loss symbol were stronger than positive associations with the gain symbol. In addition, it was found that the extent to which losses loomed larger depended on the context of the slot machine experience, with losses looming implicitly larger than gains most when they were fewer in number (participants experienced a net‐gain) and least when they were the predominant outcome (participants experienced a net‐loss). Finally, in Experiment 2, a potential artifact was ruled out and a replication obtained by showing that slot machine losses implicitly loom larger whether conceptualized from the perspective of a casino player or a casino owner.

知识背景对觉察配对词间语义联系的影响

研究探讨了生物领域知识丰富者和贫乏者判断来自生物领域或一般领域亲疏度不同的配对词间联系的差异。采用2（生物领域丰富者和贫乏者）×2（生物领域配对词和一般领域配对词）×2（语义关系疏远配对词和语义关系密切配对词）混合实验设计,要求被试尽快判断4种类型共120组配对词的两个词间是否存在语义上的联系。结果发现：生物领域知识丰富者比贫乏者更倾向于接受生物领域配对词间的联系,且在判断生物领域关系疏远配对词时花费更长时间;而两者在判断一般领域配对词间的联系时,无论在接受性或反应时上均不存在差异。这一结果说明,知识背景影响个体觉察特定范畴或特定领域中观念间联系的敏感性,觉察观念间联系的能力表现出领域特殊的特征。     

Environmental representations of local communities' spokespersons in protected areas

Despite the popularization of the environmental discourse, rural environmental belief‐systems should not be viewed as homogenous. Focusing on the largest protected area in Greece, we examined heterogeneity in local environmental views. Local spokespersons elicited word associations to two stimulus terms, namely, ‘environmentalists’ and ‘protected area’. Based on association categories for both terms, we identified two sample segments. ‘Naturalists’ appealed to a naturalistic image, which shaped the core compartment of their representations. On the other hand, ‘skeptics’ provided both environmentalist claims and critical accounts. Our findings revealed that the environmental discourse was widely diffused among local spokespersons. Issues of power and participation in decision‐making processes within protected areas are discussed. For instance, dimensions of power and legitimacy were reflected in the frequency of association categories and their allocation among sample segments. Specifically, environmentalist accounts were overtly expressed by both ‘naturalists’ and skeptics, while a more socially, politically and critically inclined view was revealed by a small percentage of associations that were all elicited by ‘skeptics’. We conclude that appreciating the heterogeneity of rural environmental views can reinforce the democratic mandate in environmental policy‐making. Copyright © 2009 John Wiley & Sons, Ltd.     

Blocking a selective association in pigeons

Experiment 1 demonstrated for the first time a stimulus-reinforcer interaction in pigeons trained with free-operant multiple schedules of reinforcement. Pigeons that treadle pressed in the presence of a tone-light (TL) compound for food exhibited primarily visual stimulus control on a stimulus-element test, whereas pigeons that avoided shock in TL exhibited auditory control. In Experiment 2, this selective association was blocked in pigeons pretrained with the biologically contingency-disadvantage element of the compound (i.e., tone-food or light-shock) before TL training. When this pretraining preceded compound-stimulus training, control was now auditory in pigeons that treadle pressed for food and was visual in pigeons that avoided shock. Previous attempts at blocking this selective association were unsuccessful in pigeons (LoLordo, Jacobs, & Foree, 1982) but were successful in rats (Schindler & Weiss, 1985). Experiment 2 established that selective associations can be blocked in pigeons when the procedures that were effective with rats were systematically replicated. These results further demonstrate the cross-species generality of an associative attentional mechanism involving a biological constraint on learning in species with different dominant sensory systems.     

Implicit and explicit appraisals of the importance of intrusive thoughts

To evaluate cognitive theories of obsessions, the current study experimentally manipulated appraisals of the importance of intrusive thoughts. Undergraduate students (N = 156) completed measures of obsessive-compulsive disorder (OCD) symptoms and beliefs and were primed with a list of commonly reported unwanted thoughts. Participants were then informed that unwanted thoughts are either (1) significant and indicative of their personal values, or (2) meaningless, or participants (3) received no instructions about unwanted thoughts. Participants then completed implicit and explicit measures of self-evaluation and interpretations of their unwanted thoughts. Results indicated that the manipulation shifted implicit appraisals of unwanted thoughts in the expected direction, but not self-evaluations of morality or dangerousness. Interestingly, explicit self-esteem and beliefs about the significance of unwanted thoughts were associated with measures of OCD beliefs, whereas implicit self-evaluations of dangerousness were better predicted by the interaction of pre-existing OCD beliefs with the manipulation. Results are discussed in terms of divergent predictors of implicit and explicit responses to unwanted thoughts.     

Preschoolers prior formal mathematics education engage numerical magnitude representation rather than counting principles in symbolic ±1 arithmetic: Evidence from the operational momentum effect

In numerical cognition research, the operational momentum (OM) phenomenon (tendency to overestimate the results of addition and/or binding addition to the right side and underestimating subtraction and/or binding it to the left side) can help illuminate the most basic representations and processes of mental arithmetic and their development. This study is the first to demonstrate OM in symbolic arithmetic in preschoolers. It was modeled on Haman and Lipowska's (2021) non-symbolic arithmetic task, using Arabic numerals instead of visual sets. Seventy-seven children (4–7 years old) who know Arabic numerals and counting principles (CP), but without prior school math education, solved addition and subtraction problems presented as videos with one as the second operand. In principle, such problems may be difficult when involving a non-symbolic approximate number processing system, whereas in symbolic format they can be solved based solely on the successor/predecessor functions and knowledge of numerical orders, without reference to representation of numerical magnitudes. Nevertheless, participants made systematic errors, in particular, overestimating results of addition in line with the typical OM tendency. Moreover, subtraction and addition induced longer response times when primed with left- and right-directed movement, respectively, which corresponds to the reversed spatial form of OM. These results largely replicate those of non-symbolic task and show that children at early stages of mastering symbolic arithmetic may rely on numerical magnitude processing and spatial-numerical associations rather than newly-mastered CP and the concept of an exact number.     

数字空间联结的灵活性及其内在机制

数字空间联结一直是认知心理学领域研究的热点之一。探索数字空间联结的一个重要指标为空间-数字反应联合编码(spatial-numerical association of response codes, SNARC)效应(左/右手对小/大数反应更快更准确)。以往研究已验证SNARC效应的普遍性及其在方向上的灵活性, 并提出多种理论解释。此外, SNARC效应在加工阶段上也具有灵活性, 其原因可能有：(1)加因素法则的理解偏差; (2)观察的角度单一; (3)观察效标的差异; (4)使用任务的差异。结合以上因素, 提出双阶段(数量信息的空间表征、空间表征到反应选择)加工模型, 不同的操控因素分别作用于两个阶段可能是引起SNARC效应灵活变化的核心原因。未来研究可从对比任务差异、引入不同干扰因素等方面进一步验证双阶段加工模型, 并结合认知神经科学技术揭示数字空间联结灵活性的内在神经机制。     

Task instructions determine the visuospatial and verbal–spatial nature of number–space associations

Evidence for number–space associations comes from the spatial–numerical association of response codes (SNARC) effect, consisting in faster reaction times to small/large digits with the left/right hand, respectively. Two different proposals are commonly discussed concerning the cognitive origin of the SNARC effect: the visuospatial account and the verbal–spatial account. Recent studies have provided evidence for the relative dominance of verbal–spatial over visuospatial coding mechanisms, when both mechanisms were directly contrasted in a magnitude comparison task. However, in these studies, participants were potentially biased towards verbal–spatial number processing by task instructions based on verbal–spatial labels. To overcome this confound and to investigate whether verbal–spatial coding mechanisms are predominantly activated irrespective of task instructions, we completed the previously used paradigm by adding a spatial instruction condition. In line with earlier findings, we could confirm the predominance of verbal–spatial number coding under verbal task instructions. However, in the spatial instruction condition, both verbal–spatial and visuospatial mechanisms were activated to an equal extent. Hence, these findings clearly indicate that the cognitive origin of number–space associations does not always predominantly rely on verbal–spatial processing mechanisms, but that the spatial code associated with numbers is context dependent.
