Immediate auditory repetition of words and nonwords: An ERP study of lexical and sublexical processing

ERPs were elicited to (1) words, (2) pseudowords derived from these words, and (3) nonwords with no lexical neighbors, in a task involving listening to immediately repeated auditory stimuli. There was a significant early (P200) effect of phonotactic probability in the first auditory presentation, which discriminated words and pseudowords from nonwords; and a significant somewhat later (N400) effect of lexicality, which discriminated words from pseudowords and nonwords. There was no reliable effect of lexicality in the ERPs to the second auditory presentation. We conclude that early sublexical phonological processing differed according to phonotactic probability of the stimuli, and that lexically-based redintegration occurred for words but did not occur for pseudowords or nonwords. Thus, in online word recognition and immediate retrieval, phonological and/or sublexical processing plays a more important role than lexical level redintegration.

An experimental comparison between rival theories of rapid automatized naming performance and its relationship to reading

Two studies investigated the degree to which the relationship between Rapid Automatized Naming (RAN) performance and reading development is driven by shared phonological processes. Study 1 assessed RAN, phonological awareness and reading performance in 1010 children aged 7-10 years. Results showed that RAN deficits occurred in the absence of phonological awareness deficits. These were accompanied by modest reading delays. In structural equation modeling, solutions where RAN was subsumed within a phonological processing factor did not provide a good fit to the data, suggesting that processes outside phonology may drive RAN performance and its association with reading. Study 2 investigated Kail's (1991) proposal that speed of processing underlies this relationship. Children with single RAN deficits showed slower speed of processing than closely matched controls performing normally on RAN. However, regression analysis revealed that RAN made a unique contribution to reading even after accounting for processing speed. Theoretical implications are discussed.

Dyslexia and remediation/education: where next?

Interventions to support students with reading difficulties have existed for over 70 years. This paper rehearses the need for interventions to be grounded in theory and empirical evidence about reading processes. The suggestion that the next generation of interventions should go beyond simple context-independent small unit phonics teaching to cover context-dependent larger phonological units is evaluated. Examples of contemporary interventions that involve large units, and morphology are presented. Current interventions reported target students with literacy difficulties regardless of a diagnosis of dyslexia.

When semantics aids phonology: a processing advantage for iconic word forms in aphasia

Iconicity is the non-arbitrary relation between properties of a phonological form and semantic content (e.g. “moo”, “splash”). It is a common feature of both spoken and signed languages, and recent evidence shows that iconic forms confer an advantage during word learning. We explored whether iconic forms conferred a processing advantage for 13 individuals with aphasia following left-hemisphere stroke. Iconic and control words were compared in four different tasks: repetition, reading aloud, auditory lexical decision and visual lexical decision. An advantage for iconic words was seen for some individuals in all tasks, with consistent group effects emerging in reading aloud and auditory lexical decision. Both these tasks rely on mapping between semantics and phonology. We conclude that iconicity aids spoken word processing for individuals with aphasia. This advantage may be due to a stronger connection between semantic information and phonological forms.

Morphological awareness and reading development in bilingual English-Chinese children in Singapore

Addressing two aspects of morphological awareness – derivational and compound, this study investigates the relationships between morphological awareness and vocabulary and reading comprehension in English-Chinese bilingual primary 3 children in Singapore (N = 76). Comparable tasks in Chinese and English were administered to examine the children’s morphological awareness, vocabulary, and reading comprehension. The results show that morphological awareness is highly related to vocabulary and reading comprehension, with higher correlations between morphological awareness and reading comprehension than between morphological awareness and vocabulary. This indicates that morphological awareness may have direct influence on reading comprehension beyond the mediating effect of vocabulary. Furthermore, the results indicate that children displayed more compound than derivational morphological awareness for Chinese due to the dominance of compound morphology in Chinese. However the children also displayed similar levels of derivational and compound morphological awareness for English despite far more derivatives than compounds in English. The robust cross-linguistic correlations suggest that Chinese compound morphological knowledge plays a facilitating role not only in learning English compounds, but also in learning transparently derived words that do not involve phonological or orthographic shifts.

The acquisition of verbal paradigms in Dutch and Greek L2 children: cross-linguistic differences and inflectional defaults

Previous research with children learning a second language (L2) has reported errors with verb inflection and cross-linguistic variation in accuracy and error patterns. However, owing to the cross-linguistic complexity and diversity of different verbal paradigms, the cross-linguistic effects on the nature of default forms has not been directly addressed in L2 acquisition studies. In the present study, we compared accuracy and error patterns in verbal agreement inflections in L2 children acquiring Dutch and Greek, keeping the children’s L1 constant (Turkish). Results showed that inflectional defaults in Greek follow universal predictions regarding the morphological underspecification of paradigms. However, the same universal predictions do not apply to the same extent to Dutch. It is argued that phonological properties of inflected forms should be taken into account to explain cross-linguistic differences in the acquisition of inflection. By systematically comparing patterns in child L2 Dutch and Greek, this study shows how universal mechanisms and target language properties work in tandem in the acquisition of inflectional paradigms.

Phenology of Tayloria dubyi (Splachnaceae) in the peadands of the Cape Horn Biosphere Reserve

The sub-Antarctic Magellanic ecoregion harbors a high diversity of bryophytes, greater than the species richness of vascular plants. Despite this fact, phenological studies on bryophytes are lacking for this ecoregion and Chile. Based on the study of the sporophytic phase of Tayloria dubyi, an endemic moss from the sub-Antarctic Magellanic ecoregion, we propose a methodology for phonological studies on austral bryophytes. We defined five phenophases, easily distinguishable with a hand-lens, which were monthly recorded during 2007 and 2008 in populations of T dubyi at the Omora Ethnobotanical Park and Mejillones Bay on Navarino Island (55 degrees S) in the Cape Horn Biosphere Reserve. The sporophytic (or reproductive) phase of T. dubyi presented a clear seasonality. After growing in November, in three months (December-February) of the austral reproductive season the sporophytes mature and release their spores; by March they are already senescent. T. dubyi belongs to the Splachnaceae family for which entomochory (dispersal of spores by insects, specifically Diptera) has been detected in the Northern Hemisphere. The period of spores release in T. dubyi coincides with the months of highest activity of Diptera which are potential dispersers of spores; hence, entomochory could also take place in sub-Antarctic Magellanic ecoregion. In sum, our work: (i) defines a methodology for phenological studies in austral bryophytes, (ii) it records a marked seasonality ion the sporophyte phase of T dubyi, and (iii) it proposes to evaluate in future research the occurrence of entomochory in Splachnaceae species growing in the sub-Antarctic peatlands and forest ecosystems in the Southern Hemisphere.

Difficulties for Vietnamese when pronouncing English : Final Consonants

Vietnamese people have many difficulties when pronouncing English. Among those, this paper will firstly deal with the hypothesis “English word-final consonants are not pronounced in a native-like way by Vietnamese speakers”. Theoretical phonological research about final consonants in the Vietnamese language and English has been carried out to characterize the difficulties. Data from Vietnamese informants were collected and analyzed, then synthesized to the most significant problems. Vietnamese effort to pronounce English word-final consonants will be towards omitting, adding schwa or replacing by sounds closer to those existing in their mother-tongue. Results of native speakers’ evaluation of Vietnamese-accented final consonants are also concluded to clarify how comprehensible informants’ pronunciation is. These findings will hopefully be useful for those who are interested in the topic and for further research.

Los Principales Problemas Fonéticos y Fonológicos en la enseñanza del Español para Extranjeros

The purpose of this study is to investigate the most common phonetic and phonological difficulties in the teaching of Spanish as a foreign language. The study has been based on the following questions: Which difficulties can teachers encounter when teaching phonetics and phonology? Which difficulties can students encounter when learning phonetics and phonology? How is phonetics and phonology taught? In order to be able to investigate the difficulties, a questionnaire has been handed out to five experienced teachers. The results of the questionnaires, together with the theory, has been analysed in the analysis. The outcome of the analysis shows that several difficulties can be detected in both the teaching and in the learning process. The results of the questionnaires also show us that the teachers mostly teach phonetics the same way: through repetition and imitation, the conductive method, and very few think outside of the box to encounter new methods.

Skicklig läs- och skrivundervisning i åk 1-3 : Om lärares möjligheter och hinder

This study focuses on teachers’ opportunities and obstacles to perform skillful reading and writing instruction. It’s about the ability to accurately identify where students are in their reading and writing process and to help them develop good reading skills. It is also about the ability to recognize signs of difficulties that students may have in their written language development and to know what efforts are needed to help them advance their reading and writing skills. The research is based on teachers’ own statements and survey responses on the external conditions for teaching and on their approach, attitudes and knowledge in reading and writing. The empirical material consists of interviews, surveys and test data. The interview study was conducted with eight teachers. The questionnaire was answered by 249 teachers, while the knowledge test was conducted of 269 teachers and 31 special education teachers. Many of the teachers in this study have lack knowledge in the structure of language and common Swedish spelling rules. Furthermore, it appears that a large part of them are unaccustomed to explaining, in detail, students’ reading development and find it difficult to systematically describe the aspects of daily literacy instruction. The overall picture is that many teachers teach without having tools to reflect on how their education really affects students’ reading and writing. These shortcomings make it difficult to conduct effective literacy instruction. Once students have learned to decode or if they have reading difficulties, many teachers seem to one-sidedly focus on getting students to read more. The consequence could be that those who would need to practice more on the technical basic of reading or comprehension strategies are left without support. Lack of variety and individuality in fluency and comprehension training can challenge the students’ reading and writing development. The teachers in the study, who have the old junior school teacher and elementary teacher education, have the highest amount of knowledge of reading and writing (the test). Good education can provide student teachers with professional skills that they may develop further in their careers. Knowledge of the meaning of phonological and phonemic awareness as well as knowledge of how to count phonemes seem to be important for knowledge of reading and writing (the test). Knowledge of basic reading processes can be obtained by systematic and structured work with students’ linguistic development, and through continuous dialogues with experienced colleagues on how and why questions. This is one important way to work also in teacher training. When essential professional skills are established in the teacher education, in practice students will obtain the school’s learning goals.

The priority of temporal aspects in L2-Swedish prosody : Studies in perception and production

Foreign accent can be everything from hardly detectable to rendering the second language speech unintelligible. It is assumed that certain aspects of a specific target language contribute more to making the foreign accented speech intelligible and listener friendly, than others. The present thesis examines a teaching strategy for Swedish pronunciation in second language education. The teaching strategy “Basic prosody” or BP, gives priority to temporal aspects of Swedish prosody, which means the temporal phonological contrasts word stress and quantity, as well as the durational realizations of these contrasts. BP does not prescribe any specific tonal realizations. This standpoint is based on the great regional variety in realization and distribution of Swedish word accents. The teaching strategy consists virtually of three directives: · Stress the proper word in the sentence. · Stress proper syllables in stressed words and make them longer. · Lengthen the proper segment – vowel or subsequent consonant – in the stressed syllable. These directives reflect the view that all phonological length is stress-induced, and that vowel length and consonant length are equally important as learning goals. BP is examined in the light of existing findings in the field of second language pronunciation and with respect to the phonetic correlates of Swedish stress and quantity. Five studies examine the relation between segment durations and the categorization made by native Swedish listeners. The results indicate that the postvocalic consonant duration contributes to quantity categorization as well as giving the proper duration to stressed syllables. Furthermore, native Swedish speakers are shown to apply the complementary /V: C/ - /VC:/ pattern also when speaking English and German, by lengthening postvocalic consonants. The correctness of the priority is not directly addressed but important aspects of BP are supported by earlier findings as well as the results from the present studies.

What affects recognition most – wrong wordstress or wrong word accent?

In an attempt to find out which of the two Swedish prosodic contrasts of 1) wordstress pattern and 2) tonal word accent category has the greatest communicative weight, a lexical decision experiment was conducted: in one part word stress pattern was changed from trochaic to iambic, and in the other part trochaic accentII words were changed to accent I.Native Swedish listeners were asked to decide whether the distorted words werereal words or ‘non-words’. A clear tendency is that listeners preferred to give more‘non-word’ responses when the stress pattern was shifted, compared to when wordaccent category was shifted. This could have implications for priority of phonological features when teaching Swedish as a second language.

The relative perceptual weight of two Swedish prosodic contrasts

Abstract. In addition to 9 vowel and 18 consonant phonemes, Swedish has three prosodic phonemic contrasts: word stress, quantity and tonal word accent. There are also examples of distinctive phrase or sentence stress, where a verb can be followed by either an unstressed preposition or a stressed particle. This study focuses on word level and more specifically on word stress and tonal word accent in disyllabic words. When making curriculums for second language learners, teachers are helped by knowing which phonetic or phonological features are more or less crucial for the intelligibility of speech and there are some structural and anecdotal evidence that word stress should play a more important role for intelligibility of Swedish, than the tonal word accent. The Swedish word stress is about prominence contrasts between syllables, mainly signaled by syllable duration, while the tonal word accent is signaled mainly by pitch contour. The word stress contrast, as in armen [´arːmən] ‘the arm’ - armén [ar´meːn] ‘the army’, the first word trochaic and the second iambic, is present in all regional varieties of Swedish, and realized with roughly the same acoustic cues, while the tonal word accent, as in anden [´anːdən] ‘the duck’ - anden [`anːdən] ‘the spirit’ is absent in some dialects (as well as in singing), and also signaled with a variety of tonal patterns depending on region. The present study aims at comparing the respective perceptual weight of the two mentioned contrasts. Two lexical decision tests were carried out where in total 34 native Swedish listeners should decide whether a stimulus was a real word or a non-word. Real words of all mentioned categories were mixed with nonsense words and words that were mispronounced with opposite stress pattern or opposite tonal word accent category. The results show that distorted word stress caused more non-word judgments and more loss, than distorted word accent. Our conclusion is that intelligibility of Swedish is more sensitive to distorted word stress pattern than to distorted tonal word accent pattern. This is in compliance with the structural arguments presented above, and also with our own intuition.

Os determinantes morfogenéticos da linguagem expressiva

O presente trabalho parte de uma reinterpretação dos determinantes e da organização da linguagem expressiva em indivíduos portadores de deficiência da audição. Neste sentido, submete a uma análise crítica as condições de estruturação e aquisição de um sistema de comunicação simbólica de natureza essencialmente verbal por parte de tais indivíduos. Avalia, em particular modo, a perspectiva de uma organização fonológica do discurso em portadores de surdez profunda “pré-linguagem~, como um processo que ultrapassa as possibilidades d e uma mera aprendizagem. A linguagem vista então como um processo semiótico de natureza percepto-expressiva, que se estabelece ao longo do desenvolvimento filogenético e ontogenético é assim interpretada, a luz de um novo modelo teórico sobre a Cognição Humana . Tal modelo, pautado em contribuições da Cibernética, da Lógica, da Linguística e da Epistemologia Genética, estabelece plataformas morfogenéticas, a partir das quais o psiquismo se organizaria. Desta maneira, 2 (dois) objetivos essenciais pretendem ser atingidos no presente e s tudo. 1º ) oferecer uma base teórica à dinâmica e processual cognitivo em que o surdo se vê envolvido ao longo da aprendizagem de um sistema verbal-simbólico - à luz de uma hipótese pré-formista, de base morfogenética. 2º) avaliar, a partir da linguagem expressiva escrita apresentada por deficientes auditivos com perda profunda ~pré-linguagem", a hipótese formulada por F. Lo P. Seminério (1980) "de uma memória morfogenética na espécie humana", a partir do que, toda a atividade cognitiva se organizaria, passando a operar segundo estruturas-código, pré-fixadas. A fim de confirmar as proposições estabelecidas, apresenta - se uma Verificação Empírica através de estudos exploratórios realizados com 6 (seis) sujeitos. Os resultados obtidos confirmam a existência de um marco seletivo e organizador de natureza audio-fonética, também entre indivíduos surdos. Constata-se que a informação veiculada é capaz de ser tratada, programada e recuperada linguisticamente, ainda que sem a possibilidade de um mecanismo de retroalimentação ao sistema que se desenvolve. O que equivale a dizer, que o indivíduo surdo apesar de não ouvir, programa à nível áudio-fonético, programação essa que vem a ser recuperada ou atualizada graças aos recursos e técnicas pedagógicas especializadas. Tais resultados sugerem uma reavaliação dos métodos psicopedagógicos usuais nesta área, podendo-se retomar sob nova orientação o debate de temas atuais, nas diretrizes das técnicas e do instrumental utilizado.
