Orthographic facilitation in oral vocabulary acquisition

An experiment investigated whether exposure to orthography facilitates oral vocabulary learning. A total of 58 typically developing children aged 8–9 years were taught 12 nonwords. Children were trained to associate novel phonological forms with pictures of novel objects. Pictures were used as referents to represent novel word meanings. For half of the nonwords children were additionally exposed to orthography, although they were not alerted to its presence, nor were they instructed to use it. After this training phase a nonword–picture matching posttest was used to assess learning of nonword meaning, and a spelling posttest was used to assess learning of nonword orthography. Children showed robust learning for novel spelling patterns after incidental exposure to orthography. Further, we observed stronger learning for nonword–referent pairings trained with orthography. The degree of orthographic facilitation observed in posttests was related to children's reading levels, with more advanced readers showing more benefit from the presence of orthography.     

Increased Stroop interference with better second-language reading skill

Skilled readers demonstrate remarkable efficiency in processing written words, unlike beginning readers for whom reading occurs more serially and places higher demands on visual attention. In the present study, we used the Stroop paradigm to investigate the relationship between reading skill and automaticity, in individuals learning a second language with a different orthographic system. Prior studies using this paradigm have presented a mixed picture, finding a positive, a negative, or no relationship between the size of Stroop interference and reading skills. Our results show that Stroop interference in the second language was positively related to reading skill (when controlled for interference in the first language). Furthermore, interference was positively related to objective but not subjective indices of the amount of exposure to the second language. We suggest that the lack of consistency in the results of earlier studies may be due, at least in part, to these studies looking at Stroop interference in isolation, rather than comparing interference between languages.     

Sound symbolic naming of novel objects is a graded function

Although linguistic traditions of the last century assumed that there is no link between sound and meaning (i.e., arbitrariness), recent research has established a nonarbitrary relation between sound and meaning (i.e., sound symbolism). For example, some sounds (e.g., /u/ as in took) suggest bigness whereas others (e.g., /i/ as in tiny) suggest smallness. We tested whether sound symbolism only marks contrasts (e.g., small versus big things) or whether it marks object properties in a graded manner (e.g., small, medium, and large things). In two experiments, participants viewed novel objects (i.e., greebles) of varying size and chose the most appropriate name for each object from a list of visually or auditorily presented nonwords that varied incrementally in the number of “large” and “small” phonemes. For instance, “wodolo” contains all large-sounding phonemes, whereas “kitete” contains all small-sounding phonemes. Participants' choices revealed a graded relationship between sound and size: The size of the object linearly predicted the number of large-sounding phonemes in its preferred name. That is, small, medium, and large objects elicited names with increasing numbers of large-sounding phonemes. The results are discussed in relation to cross-modal processing, gesture, and vocal pitch.     

Differential impacts of age of acquisition on letter and semantic fluency in Alzheimer's disease patients and healthy older adults

The degree to which the typical age of acquisition (AoA) of words and word frequency have separable influences on verbal production tasks has been strongly debated. To examine the overlap between these factors in verbal fluency tasks, the performance of Alzheimer's disease (AD) patients (N?=?34) and normal elderly controls (N?=?36) was compared on semantic (e.g., vegetables) and letter (e.g., words that begin with F) fluency tasks. These comparisons revealed that words generated for the semantic fluency task had an earlier AoA while words generated for the letter fluency task had a higher word frequency. Differences in AoA between AD patients and controls were larger for semantic than letter fluency. These results suggest that AoA has an effect on verbal production that is independent of word frequency and that AoA has a semantic locus.     

Imageability,age of acquisition,and frequency factors in acronym comprehension

In spite of their unusual orthographic and phonological form, acronyms (e.g., BBC, HIV, NATO) can become familiar to the reader, and their meaning can be accessed well enough that they are understood. The factors in semantic access for acronym stimuli were assessed using a word association task. Two analyses examined the time taken to generate a word association response to acronym cues. Responses were recorded more quickly to cues that elicited a large proportion of semantic responses, and those that were high in associative strength. Participants were shown to be faster to respond to cues which were imageable or early acquired. Frequency was not a significant predictor of word association responses. Implications for theories of lexical organisation are discussed.     

A meta-analysis of executive functioning in dyslexia with consideration of the impact of comorbid ADHD

Grapheme coding was examined in French Grade 6 and Grade 8 children and adults who learned English as a second language (L2). In Experiments 1 and 2, three conditions were compared in a letter detection task in L2: (1) simple grapheme (i.e., detect “a” in black); (2) complex language-shared grapheme (i.e., “a” in brain) and (3) complex L2-specific grapheme (i.e., “a” in beach). The data indicated that graphemes in L2 words were functional sub-lexical orthographic units for these L2 learners. Moreover, L2-specific graphemes took longer to process than language-shared complex graphemes. Using the same task, Experiment 3 examined phonological influences by manipulating the cross-language congruency of grapheme-to-phoneme mappings (detect “a” in have [congruent] vs. take [incongruent]). The outcome of this study offers preliminary evidence of graphemic coding during L2 word recognition both at the orthographic and the orthography-to-phonology mapping levels.     

The effect of bilingualism on lexical learning and memory across two language modalities: some evidence for a domain-specific,but not general,advantage

ABSTRACT

The present study was conducted to replicate bilingual advantages in short-term memory for language-like material and word learning in young adults and extend this research to the sign domain, ultimately with the goal of investigating the domain specificity of bilingual advantages in cognition. Data from 112 monolingual hearing non-signers and 78 bilingual hearing non-signers were analysed for this study. Participants completed a battery of tasks assessing sign and word learning, short-term memory, working memory capacity, intelligence, and a language and demographic questionnaire. Overall, the results of this study suggested a bilingual advantage in memory for speech-like material – no other advantage (or disadvantage) was found. Results are discussed within the context of recent large-scale experimental and meta-analytic studies that have failed to find bilingual advantages in domain-general abilities such as attention control and working memory capacity in young adults.     

From Noosphere to Theosphere: Cyclotrons, Cyberspace, and Teilhard's Vision of Cosmic Love

Two theme–setting quotations introduce this essay—that of Yeats's falcon, deaf to the falconer's call, adrift in space above the blood–dimmed tide, counterpoised to Pierre Teilhard de Chardin's call to abandon old nationalistic prejudices and build the earth. With primary references to the thought of Teilhard, along with, among others, to Ewert Cousins, Andrew M. Greeley, Karl Jaspers, Marshall McLuhan, Ilya Prigogine, Karl Rahner, Leonard Swidler, David Tracy, and Alfred North Whitehead, I argue that the most crucial intellectual paradigm shift of the twenty–first century will challenge humanity to take the turn from uncritical attachment to rigid absolutism or atomistic fragmentation toward a sense of open–ended, off–centered centeredness and fluid connections—from a static to a dynamic model of reality. Central to my argument is the Teilhardian reinterpretation of the Christian metaphors of creation, fall, incarnation, salvation, and the eschaton in the evolutionary terms of the emergence of cosmic consciousness from the chrysalis of the world of the past—from chaos to order, from biosphere via noosphere to theosphere. Facilitated by the exponential growth of populations, collaborative research, science, technology, and global communication (most dramatically manifested by the Internet), this emergent understanding of what it means to be human can, first, foster the awareness that in humanity evolution has become conscious of itself, and then, gradually, precipitate the formation of “the global village” (the mystical body of Christ), as respectful dialogue replaces diatribe and the dualistic pugilism of Samuel Huntington's “Clash of Civilizations” is gradually transformed into a nonadversarial mentality that values shared humanity and a common purpose. Thus, eons hence, empowered by love–energy, the transmutation of the human into the ultra–human can take the ultimate quantum leap into a yet higher dimension where spirit/energy is no longer in need of flesh/mass, and Earth can be safely left behind.     

易学的推类逻辑

易学中的逻辑问题,是一个在易学和逻辑学研究中被忽视的问题,但又是一个关系到对中国文化史、思想史和逻辑史的再认识的重要问题。易学中的逻辑是推类逻辑,本文给出了理由,同时以现代逻辑的方法给出了易学推类逻辑的形式系统,并作了讨论。指出易学逻辑是在中国文化背景下的以汉字表述的特有逻辑形式,建立了中国古代的普遍语言,形成了自我满足的语义系统,其在为人们提供正确的认识方法和为古代科学提供认识工具方面与西方逻辑是一致的。     

Guidelines for Writing Letters to Patients

Patient letters provide a permanent record of the genetic counseling that was provided and are unique in medical care; rarely do other health care providers send summaries written specifically to their patients and families. We surveyed genetic counseling training program directors and found that while the acquisition of patient letter-writing skills was considered important, there were no specific guidelines made available to students. To develop letter-writing guidelines, we evaluated patient letters, reviewed references on professional correspondence, surveyed the medical literature, and worked with a writing consultant. The guidelines we subsequently developed and present here include a format for writing patient letters, suggestions on presenting medical information in understandable terms, and wording considerations. These patient letter-writing guidelines are intended to serve as a guide for teaching students this important skill and as a resource for practicing health care professionals.
