Syllabic processing in handwritten word production in German children and adults

Syllables are thought to be processing units in handwritten word production. Yet, little is known about whether the orthographic characteristics of different languages influence syllabic processing during handwriting, which is critical for the evaluation and further development of extant models of handwritten language production. In the present study, we manipulated syllabic ambiguity, a characteristic of the German language, to investigate the role of syllables in handwritten word production in German. Forty-four 10 to 12-year-old children and fourteen adults were asked to write on pen tablets five-letter disyllabic words that varied in terms of their syllabic ambiguity, while their handwriting was recorded with high spatiotemporal resolution. Productions were analyzed in terms of Mean Stroke Duration (MSD) and Writing Onset Duration (WOD). Increased MSD at syllable boundaries was observed across conditions for both children and adults. There was no difference in WOD across conditions. Our findings offer support for the idea that syllables are functional units in handwriting production in German and motivate the further development of the spelling module in models of handwritten language production.     

Relationship between orthographic‐motor integration and computer use for the production of creative and well‐structured written text

Background: Orthographic‐motor integration refers to the way in which orthographic knowledge is integrated with fine‐motor demands of handwriting. A strong relationship has shown to exist between orthographic‐motor integration and students' ability to produce creative and well‐structured written text (De La Paz & Graham, 1995). This relationship is thought to be due to the cognitive load resulting from lack of automaticity in orthographic‐motor integration so that writers do not have sufficient resources to accomplish the more demanding aspects of writing. Interventions to improve children's orthographic‐motor integration result in improved written text (Jones & Christensen, 1999). Aim: This study first extended findings related to handwritten text to the relationship between typing and the length and quality of computer‐based written text. Second, it examined the efficacy of an intervention to develop proficiency in typing skills on the length and quality of students' written language. Sample: Participants in the first study were 276 Grade 8 and 9 students. In the second study 35 students in Grades 8 and 9 who exhibited very low levels of proficiency in typing were the participants. Methods: In Study 1, orthographic‐motor integration related to typing as well as handwriting was assessed for all students. They were asked to complete a piece of handwritten and computer‐based text. Students in the intervention study completed the same measures as Study 1, at pre‐ and post‐test. During the intervention half the students completed a daily typed journal and half completed a program designed to facilitate their typing skills. Results: There was a significant relationship between orthographic‐motor integration — handwriting and the length and quality of handwritten text, and a stronger relationship between orthographic‐motor integration — typing and length and quality of computer‐based text. Both intervention groups in the second study showed significant differences in writing skills from pre‐ to post‐test. However, the typing skills group showed significantly better scores on typing and quality of typewritten text than the journal group at post‐test. The impact of the intervention was specific to typewritten text. There was no difference in length or quality of handwritten text. Conclusion: It is suggested that developing proficiency in orthographic‐motor integration related to typing allows writers to employ their cognitive resources more flexibly when working on a computer, so that they can devote attention to higher‐order processes involved in ideation, syntactic and semantic monitoring and pragmatic awareness.     

手写体文字识别的特点及神经机制

手写体文字与打印体文字的识别过程存在很大差异, 与打印体文字相比, 手写体文字的识别受文本材料的影响更大, 具体包括文字的物理结构特性、文字特性、书写风格等。有关神经机制的研究发现, 手写体文字识别加工所涉及的脑区与打印体文字有所区别, 它既包含识别打印体文字的枕叶和外侧额顶叶, 还涉及到手写体文字识别的文化特异性脑区, 包括左后侧运动皮层, 外侧前额叶和后侧顶叶皮层。手写体文字加工既涉及整体加工, 也涉及特征加工, 加工方式既有其特异性, 又有与打印体文字的共同之处。未来研究应该进一步探究大脑在识别手写体文字时, 怎样在嘈杂的视觉信息中提取目标词, 并考虑手写体文字识别理论模型的构建, 以便更好地解释手写体文字的识别过程。     

Are written and spoken recall of text equivalent?

Writing is less practiced than speaking, graphemic codes are activated only in writing, and the retrieved representations of the text must be maintained in working memory longer because handwritten output is slower than speech. These extra demands on working memory could result in less effort being given to retrieval during written compared with spoken text recall. To test this hypothesis, college students read or heard Bartlett's "War of the Ghosts" and then recalled the text in writing or speech. Spoken recall produced more accurately recalled propositions and more major distortions (e.g., inferences) than written recall. The results suggest that writing reduces the retrieval effort given to reconstructing the propositions of a text.     

A SURVEY OF WRITING INSTRUCTION IN ELEMENTARY LANGUAGE ARTS CLASSROOMS

Abstract

The purpose of the study was (1) to determine to what extent children, in a large southern state, are given opportunities to engage in process writing, and (2) to determine whether teachers have incorporated activities and strategies supported by current research findings on process writing into their language arts programs. A survey of teachers in randomly selected counties was conducted to determine and analyze the following information: 1. sources of content and instructional materials used in the language arts curriculum.

2. organizational patterns used in language arts instruction.

3. time spent in various types of writing.

4. time spent in each of the stages of process writing.

Data collected from the surveys indicated a textbook orientation to language instruction, small amounts of time spent in prewriting or writing activities, and a preference for teacher-controlled writing processes, such as teacher selection of writing topics and teacher editing of student writing. Factors that mitigate for or against the change process and models for teacher inservice that facilitate new instructional practices are discussed.     

Partial Knowledge of Word Meanings: Thematic and Taxonomic Representations

The type of information (taxonomic or thematic) available at different levels of knowledge was investigated. Following extensive norming to identify taxonomic and thematic associates of low-frequency nouns, participants determined if taxonomic or thematic associates were meaningfully related to target words at three levels of knowledge: target words they correctly defined (known), recognized as familiar (frontier), or mistakenly denied as part of the language (unknown). In another experiment, participants reported which type of relationship (taxonomic or thematic) was preferred. Results indicated that both types of information were available at all levels of knowledge. However, accuracy and preference were greater for taxonomic associates across word levels. A differential increase in available thematic information relative to taxonomic information was found. Implications for the acquisition and representation of word meanings are discussed.     

Selective impairment of thematic role assignment in sentence processing

We report the performance of a brain-damaged subject showing a particularly pure dissociation between impairment in processing thematic roles and spared ability to process the morphological structure of sentences. The thematic role processing impairment was observed in both comprehension and production of active and passive reversible sentences, although it was more severe for the latter sentence type. This pattern of performance poses interesting challenges for current conceptions of the nature of language breakdown in aphasia and for models of normal sentence processing.     

INFLUENCE OF SPOKEN LANGUAGE ON THE INITIAL ACQUISITION OF READING/WRITING: CRITICAL ANALYSIS OF VERBAL DEFICIT THEORY

This article presents the results of a quasi-experimental study of whether there exists a causal relationship between spoken language and the initial learning of reading/writing. The subjects were two matched samples each of 24 preschool pupils (boys and girls), controlling for certain relevant external variables. It was found that there was no causal relationship between the initial reading/writing performance and the language variables that have traditionally been regarded as relevant in facilitating the learning of reading/writing (vocabulary, articulation, and auditory memory). Phonemic awareness, however, was strongly causally related with the writing of simple words.     

Overlap and Uniqueness: Linguistic Componential Traits Contributing to Expressive Skills in English as a Foreign Language

This study identified robust predictors of expressive skills in academic English as a foreign language. The participants were 92 Korean-speaking learners of English. The field test of the Pearson Test of English Academic was used as a secondary data analysis. Four communicative skills (reading, writing, listening, and speaking) and six enabling linguistic traits (written discourse, oral fluency, grammar, pronunciation, spelling, and vocabulary) were analyzed using writing and speaking skills as dependent variables. The greatest overlapping variance was found in the relationship between reading and writing. When listening and speaking skills were controlled, the unique variance accounted by reading in the prediction of writing became marginal. The results of this study demonstrated that L2 oral language skills became increasingly important to L2 writing outcomes as language proficiency improved over time.     

生命性在句子加工中作用的ERP研究

生命性广泛地渗透到人类语言系统中发挥其作用。本文主要结合最新和经典的有关生命性的ERP研究探讨了生命性信息起作用的模式和时间进程。在句子加工过程中,生命性影响论元的加工并影响题元结构的建构和解释。以往研究表明,生命性违反有时引发的是N400效应,有时引发的是P600效应,少数情况还表现出N400-P600的双相模式。生命性在句子加工中的作用还跟多种变量存在交互作用,语境、题元可逆性、论元之间的语义关系、动词类型和其固有的题元结构都可能影响生命性信息起作用的模式。文章最后进行总结和展望,并提出未来研究仍有必要继续探讨生命性信息加工的时间神经动态性及其在句子加工中的具体作用机制。     

Writing product and process in children with English as an additional language

ABSTRACT

Children draw on limited cognitive resources to write and these resources are under more demand when writing in English as an additional language (EAL). This study investigated the relationship between writing process measures along with two language measures, phonological awareness and lexical retrieval, and measures of writing product. Thirty-nine EAL children took part in the study and their writing was digitised so that execution speed, burst length, and the pattern of pauses were available for analysis. The results found that lexical retrieval was significantly associated, indirectly through execution speed and burst length, with the number of words, lexical richness, and writing quality. The results are discussed in the context of common underlying proficiency theory and lexical retrieval as part of the translation process of writing.

Teaching Creative Writing Skills to Primary School Children in Hong Kong: Discordance Between the Views and Practices of Language Teachers

Although creativity has been valued in ancient and contemporary Chinese literature, the degree to which creativity is valued and incorporated into teaching by Chinese language teachers is not known. This information is important given that creativity has been increasingly recognized in the education literature as a component of effective writing. The purpose of this study was to compare the views of Chinese language teachers in Hong Kong about creativity and the acquisition of creative writing skills by primary school children, and their teaching practices. A total of 449 Chinese language teachers, employed at primary schools throughout Hong Kong completed a survey questionnaire. The 14‐item questionnaire focused on teachers' views of creativity, their perceptions of how to develop students' creativity, their awareness of creative writing strategies, and teaching practices related to creative writing. With respect to the definition of creativity, teachers identified imagination foremost, followed by inspiration, and original ideas. Teachers identified developing students' confidence, and providing an open atmosphere as essential means of fostering creativity. Despite the apparent value of creativity expressed by the teachers and their familiarity with methods for enhancing creativity, the majority reported using traditional methods of teaching writing. Strategies are recommended for reconciling this discrepancy, and promoting creative writing skills by primary school teachers in Hong Kong and other Chinese speaking societies.     

The coordinated interplay of scene, utterance, and world knowledge: evidence from eye tracking

Two studies investigated the interaction between utterance and scene processing by monitoring eye movements in agent–action–patient events, while participants listened to related utterances. The aim of Experiment 1 was to determine if and when depicted events are used for thematic role assignment and structural disambiguation of temporarily ambiguous English sentences. Shortly after the verb identified relevant depicted actions, eye movements in the event scenes revealed disambiguation. Experiment 2 investigated the relative importance of linguistic/world knowledge and scene information. When the verb identified either only the stereotypical agent of a (nondepicted) action, or the (nonstereotypical) agent of a depicted action as relevant, verb-based thematic knowledge and depicted action each rapidly influenced comprehension. In contrast, when the verb identified both of these agents as relevant, the gaze pattern suggested a preferred reliance of comprehension on depicted events over stereotypical thematic knowledge for thematic interpretation. We relate our findings to language comprehension and acquisition theories.     

Patterns of discourse production among neurological patients with fluent language disorders

Dissociations between impairments in microlinguistic and macrolinguistic abilities were examined in brain-damaged patients to assess whether these abilities are psychologically and neurologically distinct. The discourse productions of three groups of patients with equally severe fluent language disorders, but varying neuropathology and varying profiles of associated nonlinguistic cognitive impairments, were analyzed. Patients with fluent aphasia secondary to a single left-hemisphere CVA showed the greatest impairment on syntactic and lexical error measures taken to reflect microlinguistic abilities, but normal performance on measures of macrolinguistic organization (i.e., thematic coherence). Patients with probable Alzheimer's Disease were impaired on thematic coherence measures, but not on measures reflecting microlinguistic syntactic and phonological processes. Closed head injury patients whose primary clinical symptom was a fluent language disorder were impaired on both microlinguistic and macrolinguistic measures, which appears to parallel their deficits both in language-specific and in nonspecific, higher-order, diffusely organized cognitive processes.     

Do handwritten words magnify lexical effects in visual word recognition?

An examination of how the word recognition system is able to process handwritten words is fundamental to formulate a comprehensive model of visual word recognition. Previous research has revealed that the magnitude of lexical effects (e.g., the word-frequency effect) is greater with handwritten words than with printed words. In the present lexical decision experiments, we examined whether the quality of handwritten words moderates the recruitment of top-down feedback, as reflected in word-frequency effects. Results showed a reading cost for difficult-to-read and easy-to-read handwritten words relative to printed words. But the critical finding was that difficult-to-read handwritten words, but not easy-to-read handwritten words, showed a greater word-frequency effect than printed words. Therefore, the inherent physical variability of handwritten words does not necessarily boost the magnitude of lexical effects.
