In this study, we aimed to investigate the difficulties highly math‐anxious individuals (HMA) may face when having to estimate a number's position in a number line task. Twenty‐four HMA and 24 low math‐anxiety (LMA) individuals were presented with four lines with endpoints 0–100, 0–1,000, 0–100,000, and 267–367 on a computer monitor on which they had to mark the correct position of target numbers using the mouse. Although no differences were found between groups in the frequency of their best‐fit model, which was linear for all lines, the analysis of slopes and intercepts for the linear model showed that the two groups differed in performance on the less familiar lines (267–367 and 0–100,000). Lower values for the slope and higher values for the intercept were found in the HMA group, suggesting that they tended to overestimate small numbers and underestimate large numbers on these non‐familiar lines. Percentage absolute error analyses confirmed that HMA individuals were less accurate than their LMA counterparts on these lines, although no group differences were found in response time. These results indicate that math anxiety is related to worse performance only in the less familiar and more difficult number line tasks. Therefore, our data challenge the idea that HMA individuals might have less precise numerical representations and support the anxiety–complexity effect posited by Ashcraft and colleagues. 相似文献

According to the guise of the good thesis, we desire things under the ‘guise of the good.’ Here I sympathetically articulate a generic formulation of the guise of the good thesis, and address a problem for the view, which I call the problem of partiality. The problem is, roughly, that our partial pro-attitudes –for example, our special concern for ourselves –do not correspond to what is absolutely good. I criticize three solutions to the problem, and propose an alternative strategy, on which partial pro-attitudes constitute a species of illusion. 相似文献

In this study, we tested the linguistic relativity hypothesis by studying the effect of grammatical gender (feminine vs. masculine) on affective judgments of conceptual representation in Italian and German. In particular, we examined the within- and cross-language grammatical gender effect and its interaction with participants’ demographic characteristics (such as, the raters’ age and sex) on semantic differential scales (affective ratings of valence, arousal and dominance) in Italian and German speakers. We selected the stimuli and the relative affective measures from Italian and German adaptations of the ANEW (Affective Norms for English Words). Bayesian and frequentist analyses yielded evidence for the absence of within- and cross-languages effects of grammatical gender and sex- and age-dependent interactions. These results suggest that grammatical gender does not affect judgments of affective features of semantic representation in Italian and German speakers, since an overt coding of word grammar is not required. Although further research is recommended to refine the impact of the grammatical gender on properties of semantic representation, these results have implications for any strong view of the linguistic relativity hypothesis. 相似文献

以往关于时间与金钱奖励选择问题的探讨主要从员工工龄视角着手。但这一视角不能直接解释外部环境资源短缺时, 员工对时间与金钱奖励选择偏好的差异问题。本文依据生命史理论, 探讨外部环境资源(如就业资源和自然资源)短缺与否对员工选择时间和金钱奖励偏好的影响及内在机制。本文以即将步入职场的大学生和企业员工为样本, 发现不管是外在就业资源短缺还是外在自然资源短缺都会促使员工更加偏好金钱而非时间奖励, 内在机制是外部环境资源短缺时人们的心理表征更具体, 并且这一现象在高物质主义者身上更为明显(实验1和2)。本文结尾讨论了对资源短缺、时间和金钱等研究领域的理论突破与推进。 相似文献

汉语主动句、被动句的命题表征项目顺序特点 总被引:2,自引:1,他引:1
以中国大学生为被试,采用句子—图画验证任务(sentence-picture verification task )探讨了中国学生理解汉语主动句、被动句所形成的命题表征中项目顺序特点。结果表明,无论是语义水平较高的不可逆句,还是语义水平较低的可逆句,中国学生理解汉语主动句、被动句所建构的命题表征中项目顺序均为“施事→受事”。本研究结果初步表明,中国学生理解汉语主动句和被动句时,能根据它们不同的表层结构(汉语主动句的语言表达顺序为“施事→受事”、汉语被动句的语言表达顺序为“受事→施事”)建构相同的深层结构(语义内容的命题表征项目顺序“施事→受事”),可能是一个按照“施事→受事”固定方向进行的系列认知心理加工的过程 相似文献

外界环境中物体位置与空间关系在记忆中如何表征,一直是空间认知研究领域探讨和争论的热点问题。该文从空间表征的参照框架、朝向特异性、组织结构和存储内容四个方面,系统回顾了近年来对空间表征形成机制与内在特征的理论探讨。在此基础上,进一步讨论了当前空间表征研究中存在的生态效度问题,以及以后将虚拟环境技术引入到空间认知研究中的发展趋势 相似文献

数量表征(numerical representation)指与特定数量相联系的心理表征。长期以来抽象的数量表征假说占据主导地位, 但随着自动化加工范式和脑成像技术的发展, 数量表征存在符号特异性的证据已不断涌现。其中, 最近有两个理论认为数量表征可能同时存在符号特异性和符号非特异性。计算的模型假说提出非符号数量和符号数字在总和编码阶段具有符号特异性, 而在之后的位置编码阶段具有符号非特异性。双重编码的延伸假说则认为数量表征在自动编码阶段具有符号特异性, 然后在有意编码阶段, 受任务要求影响, 数量表征向实时的抽象表征过渡。已有大量行为和神经基础研究为以上假说提供了证据, 但数量表征动态变化的内在机制和脑区还有待探索, 未来应该在发展、跨文化、自动加工范式与神经成像相结合、单细胞记录技术等方向继续开展数量表征研究。 相似文献

ABSTRACT— The motor-program concept, emphasizing how actions are represented in the brain, helped bring the study of motor control into the realm of cognitive psychology. However, interest in representational issues was in limbo for much of the past 30 years, during which time the focus was on biomechanical and abstract accounts of the constraints underlying coordinated movement. We review recent behavioral and neuroscientific evidence that highlights multiple levels of constraints in bimanual coordination, with an emphasis on work demonstrating that a primary source of constraint arises from the manner in which action goals are represented. 相似文献
