According to the weak version of linguistic relativity, also called the Sapir-Whorf hypothesis, the features of an individual’s native language influence his worldview and perception. We decided to test this hypothesis on the sufficient conditional and the necessary conditional, expressed differently in Chinese and French. In Chinese, connectors for both conditionals exist and are used in everyday life, while there is only a connector for the sufficient conditional in French. A first hypothesis follows from linguistic relativity: for the necessary conditional, (...) better logic performance is expected in Chinese participants rather than French participants. As a second hypothesis, for all participants, we expect performance on the sufficient conditional to be better than on the necessary conditional. Indeed, despite the isomorphism of the two conditionals, they differ in how information is processed for reasoning. We decided to study reasoning under uncertainty as it reflects reality more accurately. To do so, we analyzed the coherence of participants using de Finetti’s theory for deduction under uncertainty. The results of our study show no significant difference in performance between Chinese and French participants, neither on the sufficient conditional nor on the necessary conditional. Thus, our first hypothesis derived from the weak version of linguistic relativity is not confirmed. In contrast, our results confirm the second hypothesis in two out of three inference schemas.

"Rationality: Contexts and Constraints" is an interdisciplinary reappraisal of the nature of rationality. In method, it is pluralistic, drawing upon the analytic approaches of philosophy, linguistics, neuroscience, and more. These methods guide exploration of the intersection between traditional scholarship and cutting-edge philosophical or scientific research. In this way, the book contributes to development of a suitably revised, comprehensive understanding of rationality, one that befits the 21st century, one that is adequately informed by recent investigations of science, pathology, non-human thought, emotion, (...) and even enigmatic Chinese texts that might previously have seemed to be expressions of irrationalism. Addresses recent challenges and Identifies a direction for future research on rationalityInvestigates the relationship between rationality and mental disorders, such as delusion and depressionAssesses reasoning in artificial intelligence and nonhuman animalsReflects on ancient Chinese Philosophy and possible cultural differences in human psychology Employs philosophical reflection, along with linguistic, probabilistic, and logical techniques.

English uses the horizontal spatial metaphors to express time (e.g., the good days ahead of us). Chinese also uses the vertical metaphors (e.g., 'the month above' to mean last month). Do Chinese speakers, then, think about time in a different way than English speakers? Boroditsky [Boroditsky, L. (2001). Does language shape thought? Mandarin and English speakers' conceptions of time. Cognitive Psychology, 43(1), 1-22] claimed that they do, and went on to conclude that 'language is a powerful tool in shaping habitual (...) thought about abstract domains' (such as time). By estimating the frequency of usage, we found that Chinese speakers actually use the horizontal spatial metaphors more often than the vertical metaphors. This offered no logical ground for Boroditsky's claim. We were also unable to replicate her experiments in four different attempts. We conclude that Chinese speakers do not think about time in a different way than English speakers just because Chinese also uses the vertical spatial metaphors to express time. (shrink)

What do human beings use conditional reasoning for? A psychological consequence of counterfactual conditional reasoning is emotional experience, in particular, regret and relief. Adults’ thoughts about what might have been influence their evaluations of reality. We discuss recent psychological experiments that chart the relationship between children’s ability to engage in conditional reasoning and their experience of counterfactual emotions. Relative to conditional reasoning, counterfactual emotions are late developing. This suggests that children need not only competence in conditional reasoning, but also to (...) engage in this thinking spontaneously. Developments in domain general cognitive processing (the executive functions) allow children to develop from conditional reasoning to reasoning with counterfactual content and, eventually, to experiencing counterfactual emotions.

According to classical theories of language and cognition, human cognition is characterized by strong universal commonalities built around notions such as object, space, agency, number, time, and event (Clark, 1973; Miller & Johnson‐Laird, 1976). Languages select from this prelinguistic conceptual repertoire the concepts that become encoded in their lexical and grammatical stock. Language acquisition, on this view, is a mapping process in which the learner needs to figure out which sounds in the language spoken in the environment correspond to which (...) concepts from the ones already in the mind (Fodor, 1975; Gleitman, 1990; Pinker, 1994).

The aim of this paper is to analyze methodological problems of cross-cultural research in experimental philosophy. By studying five research projects, representing two distinct approaches to the examination of cross-cultural differences in philosophical intuitions, I point out the difficulties related to the content validity that appear in the choice of some cultural affiliation indicators. I criticize various indicators of cultural affiliation that are used in experimental philosophy (selfidentification, language) and suggest which indicators, and how, should be chosen in that kind (...) of research. I also argue that some problems related to bilingualism, translation, and the possible influence of language on the owned or reported philosophical intuitions may be impossible to transcend in cross-cultural research in experimental philosophy. It may be impossible to assess the differences between cultural philosophical intuitions. (shrink)

This paper is an investigation of the degree of incommensurability between Western scientific medicine and traditional Chinese medicine, focusing on the practice and theory of acupuncture. We describe the structure of traditional Chinese medicine, oriented around such concepts as yin, yang, qi, and xing, and discuss how the conceptual and explanatory differences between Western medicine and traditional Chinese medicine generate impediments to their comparison and evaluation. We argue that the linguistic, conceptual, ontological, and explanatory impediments can to a large extent (...) be overcome, and conclude that the dramatic differences between Western and traditional Chinese medicine do not provide insurmountable barriers to rational evaluation of acupuncture. We conclude with a discussion of the intentional and emotional aspects of conceptual change. (shrink)

Adopting a modified Stroop task, the authors tested the hypothesis that processing systems brought to bear on comprehension of emotional speech are attuned primarily to word evaluation in a low-context culture and language (i.e., in English), but they are attuned primarily to vocal emotion in a high-context culture and language (i.e., in Japanese). Native Japanese (Studies 1 and 2) and English speakers (Study 3) made a judgement of either vocal emotion or word evaluation of an emotionally spoken evaluative word. Word (...) evaluations and vocal emotions were comparable in extremity in the two languages. In support of the hypothesis, an interference effect by competing word evaluation in the vocal emotion judgement was significantly stronger in English than in Japanese. In contrast, an interference effect by competing vocal emotion in the word evaluation judgement was stronger in Japanese than in English. Implications for the cultural grounding of communication, emotion, and cognition are discussed. (shrink)

To talk about time, English speakers often use horizontal spatial metaphors whereas Chinese speakers use both vertical and horizontal spatial metaphors. Boroditsky showed that while Chinese-English bilinguals were faster to verify a temporal target like June comes earlier than August after they had seen a vertical spatial prime rather than a horizontal spatial prime, English monolinguals showed the reverse pattern, thus supporting the linguistic relativity hypothesis. This finding was not conceptually replicated in January and Kako's six experiments for English monolinguals. (...) In the current experiment, we failed to conceptually replicate her English monolinguals' findings: both Chinese-English bilinguals and English monolinguals were faster to verify the sentences after seeing a vertical spatial prime than a horizontal spatial prime. While we replicated Boroditsky's findings, in part, for our Chinese-English bilinguals, the similarity in the pattern of findings for both Chinese-English bilinguals and English monolinguals argues against the linguistic relativity hypothesis.
