Towards a New Kind of Semantic Normativity

Abstract

Hannah Ginsborg has recently offered a new account of normativity, according to which normative attitudes are essential to the meaningful use of language. The kind of normativity she has in mind –– not semantic but ‘primitive’ — is supposed to help us to avoid the pitfalls of both non-reductionist and reductive dispositionalist theories of meaning. For, according to her, it enables us both to account for meaning in non-semantic terms, which non-reductionism cannot do, and to make room for the normativity of meaning, which reductive dispositionalism cannot do. I argue that the main problem with Ginsborg’s account is that it fails to say what makes it possible for expressions to be governed by conditions of correct application to begin with. I do believe, however, that normative attitudes are essential to meaning, but they have to be thought of as fully semantic. And I suggest that conditions of correct application can be present only when those attitudes are present.     

The influence of multiple trials and computer-mediated communication on collaborative and individual semantic recall

Collaborative inhibition is a phenomenon where collaborating groups experience a decrement in recall when interacting with others. Despite this, collaboration has been found to improve subsequent individual recall. We explore these effects in semantic recall, which is seldom studied in collaborative retrieval. We also examine “parallel CMC”, a synchronous form of computer-mediated communication that has previously been found to improve collaborative recall [Hinds, J. M., & Payne, S. J. (2016). Collaborative inhibition and semantic recall: Improving collaboration through computer-mediated communication. Applied Cognitive Psychology, 30(4), 554–565]. Sixty three triads completed a semantic recall task, which involved generating words beginning with “PO” or “HE” across three recall trials, in one of three retrieval conditions: Individual–Individual–Individual (III), Face-to-face–Face-to-Face–Individual (FFI) and Parallel–Parallel–Individual (PPI). Collaborative inhibition was present across both collaborative conditions. Individual recall in Recall 3 was higher when participants had previously collaborated in comparison to recalling three times individually. There was no difference between face-to-face and parallel CMC recall, however subsidiary analyses of instance repetitions and subjective organisation highlighted differences in group members' approaches to recall in terms of organisation and attention to others' contributions. We discuss the implications of these findings in relation to retrieval strategy disruption.     

Face-name memory training in subjective memory decline: how does office-based training translate to everyday situations?

This study aimed to examine whether people with subjective memory decline (SMD) benefit from face-name memory training (single session) as much as older adult controls in an office-based setting. Approximately 2 months later, groups were reassessed for translation to a naturalistic setting. In the office setting, there was a significant interaction between stimulus type (cued name; uncued name) and training condition (spaced retrieval, semantic association, no training), but no group differences nor interactions. Semantic association was only beneficial for cued names, whereas spaced retrieval was beneficial in cued and uncued conditions. In the naturalistic setting, however, there were no training effects. Naturalistic performance was predicted by demographics, cognition, and motivation. All groups reported improved memory control beliefs and contentment. Our study demonstrates the benefit of simple memory strategies for older adults, including those with SMD, in office-based settings. Translation to everyday settings is complex and may require prior intervention to increase motivation.     

Semantic Externalism and Presentism

Abstract

In this paper I discuss an unconventional form of presentism which, I claim, captures better than all other versions of the doctrine the fundamental notion underpinning it, namely, the notion that ‘only what is present is real’. My proposal is to take this maxim as stating, not the rather uncontroversial view that past things are not real now, but the more radical idea that they never were. This rendition of presentism is, I argue, the only one that is neither trivial nor absurd. I examine this proposal by considering it against a sceptical hypothesis that bears similarities to it, viz., the hypothesis that the world was created five minutes ago. On this hypothesis, the past, all but five minutes of it, is unreal, in precisely the sense in which the presentism I discuss claims it is. I show that, assuming semantic externalism, this sceptical hypothesis cannot be sustained, but that a somewhat weaker hypothesis, the Creationist hypothesis that the world is 5,768 years old, cannot be refuted. Together, these conclusions enable a demarcation of those presentist intuitions that language and thought tolerate and those they do not.     

Semantic Coherence and Inconsistency in Estimating Conditional Probabilities

Two studies examined semantic coherence and internal inconsistency fallacies in conditional probability estimation. Problems reflected five distinct relationships between two sets: identical sets, mutually exclusive sets, subsets, overlapping sets, and independent sets (a special case of overlapping sets). Participants estimated P(A), P(B), P(A|B), and P(B|A). Inconsistency occurs when this constellation of estimates does not conform to Bayes' theorem. Semantic coherence occurs when this constellation of estimates is consistent with the depicted relationship among sets. Fuzzy‐trace theory predicts that people have difficulty with overlapping sets and subsets because they require class‐inclusion reasoning. On these problems, people are vulnerable to denominator neglect, the tendency to ignore relevant denominators, making the gist more difficult to discern. Independent sets are simplified by the gist understanding that P(A) provides no information about P(B), and thus, P(A|B) = P(A). The gist for identical sets is that P(A|B) = 1.0, and the gist of mutually exclusive sets is that P(A|B) = 0. In Study 1, identical, mutually exclusive, and independent sets yielded superior performance (in internal inconsistency and semantic coherence) than subsets and overlapping sets. For subsets and overlapping sets, interventions clarifying appropriate denominators generally improved semantic coherence and inconsistency, including teaching people to use Euler diagrams, 2 × 2 tables, or relative frequencies. In Study 2, with problems about breast cancer and BRCA mutations, there was a strong correlation between inconsistency in conditional probability estimation and conjunction fallacies of joint probability estimation, suggesting that similar fallacious reasoning processes produce these errors.

语义分解性在惯用语理解中的作用

惯用语是比喻性语言的一种。语义分解性的作用是惯用语理解机制争论的焦点。通过语义启动任务, 探究了汉语动宾结构的惯用语和偏正结构的惯用语的意义理解模式, 揭示语义分解性在短的SOA (300 ms)和长的SOA (800 ms)下的作用。结果发现, 语义分解性独立地影响惯用语的意义激活：当SOA短时, 语义高分解的两类惯用语均表现出显著的字面义激活效应; 当SOA长时, 语义低分解的偏正结构的惯用语的意义激活的正确率优势明显。同时, 两类惯用语的语义分解性不同导致了语义激活启动效应的差异：当SOA短时, 语义低分解的动宾结构的惯用语存在两种意义的激活效应, 语义高分解的动宾结构的惯用语和偏正结构的惯用语存在字面义的激活效应; 当SOA长时, 语义低分解的动宾结构的惯用语存在两种意义的激活效应, 语义高分解的偏正结构的惯用语存在比喻义的激活效应。研究证实语义分解性在惯用语加工早期即发挥作用, 在加工晚期, 语义高分解的动宾结构的惯用语的多种意义同时激活削弱了两种意义的启动优势。整个研究结果支持惯用语理解的混合表征模型和层级显性意义假说。     

潮汕话-普通话双言者的词汇习得年龄效应

采用潮汕话-普通话双言者为被试, 通过3个实验, 考察了词汇习得年龄效应。实验1采用汉字命名和图片命名范式, 证实了在双言者的两种语言中都存在词汇习得年龄效应。实验2和实验3分别采用语义范畴判断及声母监控任务, 在语义层面及语音层面检验了双言者的两种语言的词汇习得年龄效应的特点。结果表明, 在语义任务上发现了词汇习得年龄效应, 在语音任务上未发现。整个研究表明, 语义在汉语词汇习得年龄效应产生中具有重要作用, 支持了语义假设。     

The structure of semantic meaning: A developmental study

According to the “Semantic Differential” the connotative meaning of words can be quantified in statistically defined dimensions where every word is uniquely located on the dimensions Evaluation (E), Potency (P), and Activity (A). We studied 249 children between 9 and 18 years of age who rated 72 German nouns on 12 bipolar adjective scales. Three age groups were compared: 9–11, 12–14, and 15–18 years. Varimax‐rotated factor analysis yielded the classical EPA dimensions that were independent of age. This indicates that the basic structure and dimensionality of the semantic space is stable. On the other hand, the connotative meaning of individual words changed with age, and it was also affected by gender. In about half of the cases boys differed in their ratings from girls. Our data confirm that the EPA structure is stable, and is not affected by age. Development of connotative meaning or emotion is reflected, however, by systematic changes of the factor scores of individual words over the 10 years span studied.     

二语词汇熟悉度在双语者语义通达中的调节作用

先前很多研究表明熟练双语者可以直接通达其二语词汇的概念意义,非熟练双语者需要借助一语词汇间接通达其二语词汇的概念意义,这很可能是双语者二语词汇的熟悉度在其中发挥了调节作用。本研究使用跨语言重复启动范式考察了双语者对不同熟悉程度的二语词汇的语义通达方式。实验１以非熟练中英双语者为被试,实验２以熟练中英双语者为被试。总的结果发现,无论非熟练双语者还是熟练双语者,其在通达二语词汇概念意义时采用哪一种方式受词汇熟悉度的调节,当词汇熟悉度较高时,选择直接通达,当词汇熟悉度较低时,选择间接通达。本研究进一步支持和丰富了晚期双语者双语记忆表征中的语义通达方式从本质上属于经验性变化的观点。     

第二语言句子加工的ERP研究

研究者对第一语言句子加工的事件相关电位(ERP)进行研究,提出了句子加工三阶段模型及对应的ERP成分。第二语言(L2)句子加工的ERP研究结果很不一致。首先,从句子加工的ERP反应模式上来看,大多数研究发现L2学习者的ERP反应模式和母语者有质的差异,少数研究发现L2学习者加工L2句子的ERP模式类似母语者,但其反应的时间进程、波幅或分布与母语者有显著差异。被试的学习年龄、熟练程度以及学习者的两种语言的相似性程度可能是影响第二语言句子加工ERP反应的主要因素。
