Aamiaiskahvilasta ötökkätarjontaan. Suomen kirjoitetun yleiskielen morfosyntaktisten yhdyssanarakenteiden produktiivisuus

Tämän tutkimuksen kohde on suomen kirjoitetun yleiskielen morfosyntaktisten yhdyssanarakenteiden produktiivisuus. Tutkimuksen tärkein päämäärä on selvittää, kuinka ahkerasti erilaisia suomen kielen suomia mahdollisuuksia käytetään uusien yhdyssanojen muodostuksessa. Käytännöllistä produktiivisuutta kartoittava tutkimus täydentää kielioppien ja sanastonkuvausten antamaa kuvaa kielestä. Tutkimuksen kohteena oleva kielimuoto on kaikille kielenkäyttäjille yhteinen kirjoitettu yleiskieli. Tutkimusaineisto koostuu 28 091 uudesta yhdyssanasta, jotka on kerätty painetun median kielestä vuosina 2000–2009. Aineiston pohjana on Kotimaisten kielten keskuksen Nykysuomen sanastotietokanta, johon poimitaan uusia ja uudella tavalla käytettyjä sanoja ensisijaisesti sanakirjatyön ja kielenhuollon tarpeisiin. Tutkimusaihetta lähestytään useiden yhdyssanan osien muotoa, sanaluokkaa, määrää ja pituutta koskevien alakysymysten kautta. Tutkimus etenee yksittäisten muut-tujien käsittelystä muuttujien keskinäisiä suhteita tarkasteleviin malleihin. Tutkimuksessa käytetään kaksivaiheista metodia: Metodin ensimmäinen askel on uudessa sanastossa havaittujen rakenteiden tyyppifrekvenssin tilastollinen analyysi. Toinen askel on varsinkin matalafrekvenssisten tai tilastollisessa analyysissa muuten poikkeavaksi osoittautuneiden rakenteiden kvalitatiivinen tarkastelu. Metodi on kehitetty tätä tutkimusta varten, sillä aiemmin produktiivisuuden mittaamisessa käytetyt menetelmät eivät sellaisenaan sovi suomen kielen yhdyssanarakenteiden tutkimukseen. Tutkimusmetodien kehittäminen on tutkimuksen keskeinen tavoite. Tutkimus osoittaa, että suomen kielen uudet yhdyssanat ovat rakenteeltaan homogeenisempiä, kuin aiempia kielenkuvauksia lukemalla voisi olettaa. Uusi suomen kielen yhdyssana on todennäköisimmin kahdesta substantiivista yhdistämällä muodostettu substantiivi, jonka alkuosa on nominatiivissa eikä kongruoi jälkiosan kanssa. Ennakko-oletusta huomattavasti yleisempiä ovat myös prefiksinkaltaisella alkuosalla alkavat yhdyssanat. Genetiivialkuiset yhdyssanat puolestaan ovat ennakko-oletusta harvinaisempia. Kaikki kieliopillisesti mahdolliset yhdyssanarakenteet eivät ole lainkaan produktiivisia kielenkäytön tasolla. Tutkimus on luonteeltaan kielen rakennetta kartoittavaa perustutkimusta. Tutkimustulosten tärkeimmät sovellusalat ovat kieliteknologia ja sananmuodostuksen opetus. Tutkimus avaa useita näkökulmia jatkotutkimukselle.

Language-specific aspects of reading acquisition: the case of Russian

We have investigated Russian children’s reading acquisition during an intermediate period in their development: after literacy onset, but before they have acquired well-developed decoding skills. The results of our study suggest that Russian first graders rely primarily on phonemes and syllables as reading grain-size units. Phonemic awareness seems to have reached the metalinguistic level more rapidly than syllabic awareness after the onset of reading instruction, the reversal which is typical for the initial stages of formal reading instruction creating external demand for phonemic awareness. Another reason might be the inherent instability of syllabic boundaries in Russian. We have shown that body-coda is a more natural representation of subsyllabic structure in Russian than onset-rime. We also found that Russian children displayed variability of syllable onset and offset decisions which can be attributed to the lack of congruence between syllabic and morphemic word division in Russian. We suggest that fuzziness of syllable boundary decisions is a sign of the transitional nature of this stage in the reading development and it indicates progress towards an awareness of morphologically determined closed syllables. Our study also showed that orthographic complexity exerts an influence on reading in Russian from the very start of reading acquisition. Besides, we found that Russian first graders experience fluency difficulties in reading orthographically simple words and nonwords of two and more syllables. The transition from monosyllabic to bisyllabic lexical items constitutes a certain threshold, for which the syllabic structure seemed to be of no difference. When we compared the outcomes of the Russian children with the ones produced by speakers of other languages, we discovered that in the tasks which could be performed with the help of alphabetic recoding Russian children’s accuracy was comparable to that of children learning to read in relatively shallow orthographies. In tasks where this approach works only partially, Russian children demonstrated accuracy results similar to those in deeper orthographies. This pattern of moderate results in accuracy and excellent performance in terms of reaction times is an indication that children apply phonological recoding as their dominant strategy to various reading tasks and are only beginning to develop suitable multiple strategies in dealing with orthographically complex material. The development of these strategies is not completed during Grade 1 and the shift towards diversification of strategies apparently continues in Grade 2.

A natureza gramatical das sensações: notas céticas sobre sentido e imaginação

O texto procura recensear algumas das fontes de um discurso de espécie cética sobre o problema da atribuição de qualidades estéticas a objetos: o maior propósito deste conjunto deve entender-se como sendo um ataque à origem perceptiva dos fatos sensíveis. O autor recorre para tanto aos marcos do diálogo entre a fenomenologia e a filosofia analítica, sobretudo com G. Ryle, assim como às interrogações de L. Wittgenstein sobre o estatuto da investigação estética: nestes âmbitos, identifica o problema da imagem como fato perceptivo à necessidade de uma descrição gramatical dos juízos que envolvem estas experiências. O texto indica, finalmente, no âmbito dos escritos anti-cartesianos de Ch. S. Peirce às fontes de uma teoria do estético como filosofia da discursividade aplicada aos juízos perceptivos: sua teoria semiótica, em verdade, constituiria uma transformação radical do problema da inferência, na direção de uma teoria das formas ampliativas, ou sintéticas, do entendimento (a justificação para a validade dos procedimentos indutivos e hipotéticos para a ciência e para a descrição dos juízos denotativos).

Sobre as origens do vocabulário político medieval

O fenômeno da incorporação do corpo lexical político aristotélico transliterado do grego ao contexto latino do século XIII nos remete a problemas sobre as presenças e ausências terminológicas, não somente na tradução da Política, feita por Guilherme de Moerbeke, e nos comentários de Alberto Magno e Tomás de Aquino ao texto latino de Aristóteles, mas também à possível reverberação desses vocábulos políticos moerbekianos em alguns leitores da Política, no século XIV. Não se trata apenas de verificação de quem usou ou não usou tais ou quais termos, nem mesmo da elaboração de juízos sobre esses usos, como que para rotular pensadores; antes, trata-se de tentar individuar, a partir dos usos terminológicos, o surgimento de um novo modo de pensar e compreender a esfera da vida humana que é a dimensão pública, ou melhor, política. Tentaremos compreender, neste artigo, especificamente como emerge, a partir dessa tradução latina da Política, um novo quadro conceitual, a saber: a esfera política. Constataremos que a tradução da Política de Moerbeke consolida um novo vocabulário e um novo quadro conceitual que será, doravante, um dos fundamentos do pensamento político.

Aprendizagem e Comunicação em Bateson: A exigência de uma epistemologia Formal e Complexa

RESUMO: Para Bateson, a mudança social radicaria numa mudança epistemológica profunda que incidisse sobretudo na educação e na comunicação (onde incluía a sua teorização psicológica). Essa revolução paradigmática, baseada na lógica formal de Whitehead e Russell, evitaria discursos ditos científicos destituídos de rigor. Aqui, analisamos hermeneuticamente o seu pensamento, salientando os limites que a lógica formal encontra nas experiências éticas, religiosas e estéticas. Sem essa revolução, encontramo-nos condenados à estagnação intelectual, pois formamos cidadãos sem capacidade de aprender a aprender, que possibilitaria a capacidade de produzir abduções, inferência lógica tão necessária na produção do raciocínio humano; o seu desenvolvimento garantiria a capacidade de pensar/construir complexamente o mundo, interligando os saberes; poucos são também aqueles que explicitam e argumentam a favor das suas crenças, base axiomática da capacidade abdutiva. A organização social (via sistema educativo, formal e não formal) se constrói com sujeitos que raramente possuem mentes bem estruturadas, favorecedoras de passagem de patamares de aprendizagem para outros superiores. Antes se estimula a confusão de tipos lógicos, tomando o todo pela parte, por exemplo. Bateson critica também o sistema de avaliação quantitativo, diminuindo a possibilidade de formação do pensamento abstrato e formal, como a filosofia e a matemática exigem.

Comparing ESL electronic and face-to-face pre-writing conferences and first drafts : discourse, participation, and idea transfer /

This study was a comparative investigation of face-toface (i.e., proximate) and computer-mediated written (i.e., graphic) pre-writing conferences. The participants in this study were advanced English as a second language students. The 2 types of conferences were compared in terms of textual features, participation, and the . degree to which they were on topic. Moreover, drafts written after the 2 types of conferences were compared in terms of textual features, and the degree to which they were related to the conferences. Students produced an equivalent amount of discourse in an equivalent amount of time in the 2 types of conferences. The discourse in graphic conferences displayed greater lexical range, and some evidence suggests that it was less on-topic. Both these results likely occurred because the graphic conferences contained more discourse demonstrating interactive competence. Participation in graphic conferences was found to be as balanced or more balanced among students, and among students and the group leader combined. Overall, the drafts produced after the 2 types of conferences were of equivalent length and topical range, but some evidence suggests that drafts written after proximate conferences were more related to the conferences.

ESL students' perceptions of web-based prewriting activities /

Although much research has explored computer mediated communication for its application in second language instruction, there still exists a need for empirical results from research to guide practitioners who wish to introduce web-based activities into their instruction. This study was undertaken to explore collaborative online task-based activities for the instruction of ESL academic writing. Nine ESL students in their midtwenties, enrolled at a community college in Ontario, engaged in two separate online prewriting activities in both a synchronous and an asynchronous environment. The students were interviewed in order to explore their perceptions of how the activities affected the generation and organization of ideas for academic essays. These interviews were triangulated with examples of the students' online writing, nonparticipatory observations of the students' interactions, and a discussion with the course instructor. The results of the study reveal that a small majority of students felt that brainstorming in writing with their peers in an asynchronous online discussion created a grammatical and lexical framework that supported idea generation and organization. The students did not feel that the synchronous chat activity was as successful. Although they felt that this activity also contributed to the generation of ideas, synchronous chat introduced a level of difficulty in communication that hindered the students' engagement in the task and failed to assist them with the organization of their ideas. The students also noted positive aspects of the web-based activities that were not related to prewriting tasks, for example, improved typing and word processing skills. Directions for future research could explore whether online prewriting activities can assist students in the creation of essays that are syntactically or lexically complex.

What happens in the first 200 ms of word reading : ERP studies on visual word recognition with top-down and bottom-up approaches /

In this thesis, three main questions were addressed using event-related potentials (ERPs): (1) the timing of lexical semantic access, (2) the influence of "top-down" processes on visual word processing, and (3) the influence of "bottom-up" factors on visual word processing. The timing of lexical semantic access was investigated in two studies using different designs. In Study 1,14 participants completed two tasks: a standard lexical decision (LD) task which required a word/nonword decision to each target stimulus, and a semantically primed version (LS) of it using the same category of words (e.g., animal) within each block following which participants made a category judgment. In Study 2, another 12 participants performed a standard semantic priming task, where target stimulus words (e.g., nurse) could be either semantically related or unrelated to their primes (e.g., doctor, tree) but the order of presentation was randomized. We found evidence in both ERP studies that lexical semantic access might occur early within the first 200 ms (at about 170 ms for Study 1 and at about 160 ms for Study 2). Our results were consistent with more recent ERP and eye-tracking studies and are in contrast with the traditional research focus on the N400 component. "Top-down" processes, such as a person's expectation and strategic decisions, were possible in Study 1 because of the blocked design, but they were not for Study 2 with a randomized design. Comparing results from two studies, we found that visual word processing could be affected by a person's expectation and the effect occurred early at a sensory/perceptual stage: a semantic task effect in the PI component at about 100 ms in the ERP was found in Study 1 , but not in Study 2. Furthermore, we found that such "top-down" influence on visual word processing might be mediated through separate mechanisms depending on whether the stimulus was a word or a nonword. "Bottom-up" factors involve inherent characteristics of particular words, such as bigram frequency (the total frequency of two-letter combinations of a word), word frequency (the frequency of the written form of a word), and neighborhood density (the number of words that can be generated by changing one letter of an original word or nonword). A bigram frequency effect was found when comparing the results from Studies 1 and 2, but it was examined more closely in Study 3. Fourteen participants performed a similar standard lexical decision task but the words and nonwords were selected systematically to provide a greater range in the aforementioned factors. As a result, a total of 18 word conditions were created with 18 nonword conditions matched on neighborhood density and neighborhood frequency. Using multiple regression analyses, we foimd that the PI amplitude was significantly related to bigram frequency for both words and nonwords, consistent with results from Studies 1 and 2. In addition, word frequency and neighborhood frequency were also able to influence the PI amplitude separately for words and for nonwords and there appeared to be a spatial dissociation between the two effects: for words, the word frequency effect in PI was found at the left electrode site; for nonwords, the neighborhood frequency effect in PI was fovind at the right elecfrode site. The implications of otir findings are discussed.

The influence on children of the purpose of experiencing reading vocabulary: encoding-retrieval interactions in word perception

This research looked at conditions which result in the development of integrated letter code information in the acquisition of reading vocabulary. Thirty grade three children of normal reading ability acquired new reading words in a Meaning Assigned task and a Letter Comparison task, and worked to increase skill for known reading words in a Copy task. The children were then assessed on their ability to identify the letters in these words. During the test each stimulus word for each child was exposed for 100 msec., after which each child reported as many of his or her letters as he or she could. Familiar words, new words, and a single letter identification task served as within subject controls. Following this, subjects were assessed for word meaning recall of the Meaning Assigned words and word reading times for words in all condi tions • The resul ts supported an episodic model of word recognition in which the overlap between the processing operations employed in encoding a word and those required when decoding it affected decoding performance. In particular, the Meaning Assigned and Copy tasks. appeared to facilitate letter code accessibility and integration in new and familiar words respectively. Performance in the Letter Comparison task, on the other hand, suggested that subjects can process the elements of a new word without integrating them into its lexical structure. It was concluded that these results favour an episodic model of word recognition.

Visual word learning in good and poor readers

Forty students from regular, grade five classes were divided into two groups of twenty, a good reader group and a' poor reader group, on the basis. of their reading scores on Canadian Achievement Tests. .The subjects took. part in four experimental conditions iM which they .learned lists of pronounceable and unprono~nceable pseudowords, some with semantic referents, and responded to questions designed tci test visual perceptu~l learning and lexical ·and semantic association learning. It' was hypothesized "that the good reade~ group would be able to make use of graphemic and phonemic redundancy patterns in order to improv~·visuSl perceptual learning and lexical and semantic association lea~ningto a greater extent. than would .the poor reader gr6up. The data supported this hypothesis, and also indicated that, although the poor readers were less adept at using familiar sound and letter patterns, they were more dependent on· such pa~terns as an aid to visual recognition memory and semantic recall than were the good readers. It wa.s postulated that poor readers are in a double- ~ . bind situatio~ of having to choose between using weak graphemic-semantic associations or gr~pheme-phoneme associations which are also weak and which have hindered them in developing automaticity in. reading.

An Interactive Theorem Prover for First-Order Dynamic Logic

Dynamic logic is an extension of modal logic originally intended for reasoning about computer programs. The method of proving correctness of properties of a computer program using the well-known Hoare Logic can be implemented by utilizing the robustness of dynamic logic. For a very broad range of languages and applications in program veri cation, a theorem prover named KIV (Karlsruhe Interactive Veri er) Theorem Prover has already been developed. But a high degree of automation and its complexity make it di cult to use it for educational purposes. My research work is motivated towards the design and implementation of a similar interactive theorem prover with educational use as its main design criteria. As the key purpose of this system is to serve as an educational tool, it is a self-explanatory system that explains every step of creating a derivation, i.e., proving a theorem. This deductive system is implemented in the platform-independent programming language Java. In addition, a very popular combination of a lexical analyzer generator, JFlex, and the parser generator BYacc/J for parsing formulas and programs has been used.

Interpreting Quantifier Scope Ambiguity: Evidence of Heuristic First, Algorithmic Second Processing

The present work suggests that sentence processing requires both heuristic and algorithmic processing streams, where the heuristic processing strategy precedes the algorithmic phase. This conclusion is based on three self-paced reading experiments in which the processing of two-sentence discourses was investigated, where context sentences exhibited quantifier scope ambiguity. Experiment 1 demonstrates that such sentences are processed in a shallow manner. Experiment 2 uses the same stimuli as Experiment 1 but adds questions to ensure deeper processing. Results indicate that reading times are consistent with a lexical-pragmatic interpretation of number associated with context sentences, but responses to questions are consistent with the algorithmic computation of quantifier scope. Experiment 3 shows the same pattern of results as Experiment 2, despite using stimuli with different lexicalpragmatic biases. These effects suggest that language processing can be superficial, and that deeper processing, which is sensitive to structure, only occurs if required. Implications for recent studies of quantifier scope ambiguity are discussed.

Morphonotactic and phonotactic processing in German-speaking adults

Based on the theoretical framework of Dressler and Dziubalska-Kołaczyk (2006a,b), the Strong Morphonotactic Hypothesis will be tested. It assumes that phonotactics helps in decomposition of words into morphemes: if a certain sequence occurs only or only by default over a morpheme boundary and is thus a prototypical morphonotactic sequence, it should be processed faster and more accurately than a purely phonotactic sequence. Studies on typical and atypical first language acquisition in English, Lithuanian and Polish have shown significant differences between the acquisition of morphonotactic and phonotactic consonant clusters: Morphonotactic clusters are acquired earlier and faster by typically developing children, but are more problematic for children with Specific Language Impairment. However, results on acquisition are less clear for German. The focus of this contribution is whether and how German-speaking adults differentiate between morphonotactic and phonotactic consonant clusters and vowel-consonant sequences in visual word recognition. It investigates whether sub-lexical letter sequences are found faster when the target sequence is separated from the word stem by a morphological boundary than when it is a part of a morphological root. An additional factor that is addressed concerns the position of the target cluster in the word. Due to the bathtub effect, sequences in peripheral positions in a word are more salient and thus facilitate processing more than word-internal positions. Moreover, for adults the primacy effect most favors word-initial position (whereas for young children the recency effect most favors word- final position). Our study discusses effects of phonotactic vs. morphonotactic cluster status and of position within the word.

The nature of compounds: A psychocentric perspective

Although compound words often seem to be words that themselves contain words, this paper argues that this is not the case for the vast majority of lexicalized compounds. Rather, it is claimed that as a result of acts of lexical processing, the constituents of compound words develop into new lexical representations. These representations are bound to specific morphological roles and positions (e.g., head, modifier) within a compound word. The development of these positionally bound compound constituents creates a rich network of lexical knowledge that facilitates compound processing and also creates some of the well-documented patterns in the psycholinguistic and neurolinguistic study of compounding.
