The roles of cognitive and language abilities in predicting decoding and reading comprehension: comparisons of dyslexia and specific language impairment

This study aimed to (a) explore the roles of cognitive and language variables in predicting reading abilities of two groups of individuals with reading disabilities (i.e., dyslexia and specific language impairment) and (b) examine which variable(s) is the most predictive in differentiating two groups. Inclusion/exclusion criteria applied to categorize the two groups yielded a total of 63 participants (n = 44 for the dyslexia; n = 19 for the specific language impairment). A stepwise multiple regression approach was conducted to examine which cognitive and/or language variables made the largest contribution to reading abilities (i.e., Phonetic Decoding Efficiency, Word Attack, Sight Word Efficiency, and Passage Comprehension). Results revealed that there were significant differences in which measures of cognitive and language ability predicted individuals with dyslexia and speech and language impairments reading ability, showing that the cognitive and language variables underlying their difficulty with reading abilities were not the same across the two groups. A discriminant function analysis showed that a measure of Verbal Comprehension, Phonological Awareness, and Phonetic Decoding Efficiency can be used to differentiate the two groups. These findings support the tenet that dyslexia and specific language impairment are two subgroups of reading disabilities and that thorough diagnostic evaluations are needed to differentiate between these two subgroups. Distinctions of this nature are central to determining the type and intensity of language-based interventions.     

The effects of first language orthographic features on word recognition processing in English as a second language

This study investigated the possible effects of first language (L1) orthographic characteristics on word recognition in English as a second language (ESL). Case alternation was used to examine the impact of visually distorted words of different types on fluent ESL readers' word recognition in naming. Visual distortion of word shape (i.e., cAsE aLtErNaTiOn) was utilized because, although visually distorted words have lost word-shape cues, they preserve the cue value of words (i.e., spelling patterns). It, therefore, was hypothesized that if one is sensitive to alphabetic orthography, or if one's inner mechanism of processing an alphabetic word is efficient, then the visual disruption of word-shape cues should not affect one's sensitivity to sequences of letters in words. In other words, this study focused on the magnitude of the effect of case alternation in word recognition as an index of the sensitivity to alphabetic words. Results showed that the magnitude of the case alternation effect in a naming task was significantly larger for the ESL participants whose L1 is not alphabetic (i.e., Chinese and Japanese) than the ESL participants whose L1 is alphabetic (i.e., Iranians -- Persian as L1). This result seems to indicate that the Persian speakers, due to the facilitating influence of their L1 orthography, were less influenced by case alternation than the Chinese and Japanese speakers, whose L1 orthographies are not alphabetic. This finding suggests that the first language orthographic features affect the orthographic coding mechanisms (i.e., word recognition mechanisms) in a second language.     

Evaluating Rural Preschool Speech‐Language Services: consumer satisfaction

Consumer satisfaction with the delivery of preschool speech‐language services in a sparsely populated rural region of Canada was investigated. A 22‐item questionnaire was developed to evaluate parent satisfaction for seven targeted service themes. Of the 152 parents identified for study, 79 (52%) completed and returned the questionnaire. Although results indicated generally positive levels of parent satisfaction for the services provided significant differences emerged for four service themes: intervention format, parent support, parent satisfaction, and service convenience. Similar patterns were found for two service themes (i.e., intervention format and parent support), when parent responses were sub‐categorised and analysed according to children's preschool program outcome (i.e., goals reached versus transferred to school). The speech‐language service themes rated the highest by parents included referral process, assessment process, and parent intervention. Parent evaluations were less supportive for three additional service themes: service convenience, parent support, and overall parent satisfaction. Intervention format received the lowest parent rating. The results are suggestive of ways in which the speech‐language service may be enhanced to achieve greater levels of consumer satisfaction.     

Children’s private speech during algorithmic and heuristic drawing tasks

This cross-sectional study examined the private speech and task-related activity of 108 school-aged children while they drew pictures of real objects (i.e., a house, a person, and an animal) and make-believe objects (i.e., a house, a person, and an animal) to investigate developmental and task-related changes in self-regulation. Composite scores for each first-grade (N=36), third-grade (N=36), and fifth-grade (N=36) participant were calculated from the repeated raw frequencies of overall private speech and private speech in conjunction with task-related behavior during the two types of drawing activities (i.e., real and make-believe). Scores were then analyzed using regression analysis and 3×2 (Grade×Task Type) ANOVA’s to explore study hypotheses. This study found that: (1) there was a concave curvilinear developmental trend in overall private speech production, (2) participants utilized more private speech during heuristic (i.e., make-believe) drawing tasks than algorithmic (i.e., real) drawing tasks, and (3) school-aged children used private speech in conjunction with task-related behavior in a different manner during the two types of drawing activities. These findings contribute to the Vygotskian perspective regarding the development and function of private speech.

Mother-child conversations about pictures and objects: referring to categories and individuals

The distinction between individuals (e.g., Rin-Tin-Tin) and categories (e.g., dogs) is fundamental in human thought. Two studies examined factors that influence when 2- to 3-year-old children and adults focus on individuals versus categories. Mother-child dyads were presented with pictures and toys (e.g., a picture of a boat or a toy boat). Conversations were coded for references to generic categories ("Dogs are furry"), ostensive labels ("This is a dog"), or specific individuals ("Lassie"). Overall, pictures generated more talk about categories; objects generated more talk about individuals. However, when objects could not be manipulated, speakers expressed relatively more category references. These results suggest that representations (in the form of pictures or objects-on-display) encourage young children and parents alike to think about categories.     

The impact of L1 writing system on ESL knowledge of vowel and consonant spellings

Orthographic knowledge, the general ability to learn, store, and use information about the orthographic form of words (Stanovich & West, 1989), is a crucial skill for supporting literacy. Although the development of first language (L1) orthographic awareness is impacted by the characteristics of a learner’s L1 writing system, relatively little is known about what impact the L1 may have on second language (L2) orthographic awareness. In this study, English language learners from three L1s (French, Hebrew, Mandarin Chinese), plus L1 English speakers, were tested on their English spelling knowledge using a word-pseudohomophone discrimination task. In addition to allowing for the cross-linguistic comparisons, items were designed to examine whether learners had differing performance on pseudohomophones (misspellings) that targeted vowels versus consonants. Consistent with previous research (e.g., McBride-Chang, Bialystok, Cong, & Li, 2004), the L1 Chinese speakers had the highest (L2) accuracy, followed by the L1 Hebrew and the L1 French speakers. The participants from non-alphabetic languages (Hebrew and Chinese) had significantly lower accuracy on items with misspellings involving vowels compared to consonants, and the size of the vowel-consonant accuracy difference varied substantially across L1 groups. The results demonstrate that the characteristics of a learner’s L1 writing system, particularly the existence of vowel and consonant graphemes, impact the development of L2 orthographic knowledge and sensitivity to different types of word misspellings.

How Do Children Acquire Early Grammar and Build Multiword Utterances? A Corpus Study of French Children Aged 2 to 4

In the last 50 years, researchers have debated over the lexical or grammatical nature of children's early multiword utterances. Due to methodological limitations, the issue remains controversial. This corpus study explores the effect of grammatical, lexical, and pragmatic categories on mean length of utterances (MLU). A total of 312 speech samples from high‐low socioeconomic status (SES) French‐speaking children aged 2–4 years were annotated with a part‐of‐speech‐tagger. Multiple regression analyses show that grammatical categories, particularly the most frequent subcategories, were the best predictors of MLU both across age and SES groups. These findings support the view that early language learning is guided by grammatical rather than by lexical words. This corpus research design can be used for future cross‐linguistic and cross‐pathology studies.     

二语习得中语音系统与非语音系统的辩证对应关系

语音系统为语言第一性,非语音系统为语言的第二性。语义是语言单位的意义,是思维的直接所指,即语言所指,它包括语音层面的语言所指和文字层面的语言所指,语义可以单独和语音或者文字结合,也可以和语音、文字三者结合在一起。语法是一种先天的内在语言能力,需要后天语言环境的刺激派生出语言现实,包括了语音语言现实和文字语言现实。习得语言,学习者必须明确学习目标:侧重学习语音语言,侧重学习文字语言,或者两者都一样重要,综合语言是最终学习目标。不同的学习目标,其学习方法和教学方法是有区别的。     

Preschool children use linguistic form class and pragmatic cues to interpret generics

Generic noun phrases (e.g., "Bats live in caves") are important for expressing knowledge about abstract kinds. Past work has found that parents frequently use generic noun phrases in their speech to young children. However, little is known regarding how children understand these expressions, nor which cues signal generic meaning. The present set of 5 studies examined the influence of linguistic form class (e.g., "What color are dogs?" [generic] versus "What color are the dogs?" [nongeneric]) and of pragmatic context (e.g., "What color are they?" in the presence of either a single exemplar [generic] or multiple exemplars [nongeneric]). Participants were 2-year-olds (N = 42), 3-year-olds (N = 40), 4-year-olds (N = 40), and adults (N = 51). The data indicate that by 2 years of age, children use linguistic form class, and by 3 years of age, children use pragmatic context. These findings demonstrate that young children have begun to understand the distinction between generic and nongeneric noun phrases from a very young age, and that identification of generics is signaled not by formal or pragmatic cues alone, but by a combination of information from both language form and pragmatic context. It is suggested that children make use of multiple linguistic and conceptual cues to acquire and interpret generics.     

Developmental Differences in Infant Attention to the Spectral Properties of Infant-directed Speech

Across several independent studies, infants from a few days to 9 months of age have shown preferences for infant-directed (ID) over adult-directed (AD) speech. Moreover, 4-month-olds have been shown to prefer sine-wave analogs of the fundamental frequency of ID speech, suggesting that exaggerated pitch contours are prepotent stimuli for infants. The possibility of similar preferences by 1-month-olds was examined in a series of experiments, using a fixation-based preference procedure. Results from the first 2 experiments showed that 1-month-olds did not prefer the lower-frequency pitch characteristics of ID speech, even though 1-month-olds were able to discriminate low-pass filtered ID and AD speech. Since low-pass filtering may have distorted the fundamental frequency characteristics of ID speech, 1-month-olds were also tested with sine-wave analogs of the fundamental frequencies of the ID utterances. Infants in this third experiment also showed no preference for ID pitch contours. In the fourth experiment, 1-month-olds preferred a natural recording of ID speech over a version which preserved only its lower frequency prosodic features. From these results, it is argued that, although young infants are similar to older infants in their attraction to ID speech, their preferences depend on a wider range of acoustic features (e.g., spectral structure). It is suggested that exaggerated pitch contours which characterize ID speech may become salient communicative signals for infants through language-rich, interactive experiences with caretakers and increased perceptual acuity over the first months after birth.

Early Language Experience in a Tseltal Mayan Village

Daylong at-home audio recordings from 10 Tseltal Mayan children (0;2–3;0; Southern Mexico) were analyzed for how often children engaged in verbal interaction with others and whether their speech environment changed with age, time of day, household size, and number of speakers present. Children were infrequently directly spoken to, with most directed speech coming from adults, and no increase with age. Most directed speech came in the mornings, and interactional peaks contained nearly four times the baseline rate of directed speech. Coarse indicators of children’s language development (babbling, first words, first word combinations) suggest that Tseltal children manage to extract the linguistic information they need despite minimal directed speech. Multiple proposals for how they might do so are discussed.     

Stress typicality effect in Chinese advanced and intermediate ESL learners

In English, positions of lexical stress in disyllabic words are associated with word categories; that is, nouns tend to be stressed more often on the first syllable, whereas verbs are more likely to be stressed on the second syllable (i.e. subject (noun) vs. subject (verb)). This phenomenon, which is called the stress typicality effect, has been shown to facilitate word recognition to native English speakers. However, there is little research on whether it also facilitates word recognition to non-native speakers of English, in particular, to English learners with a tonal first language. To fill this research gap, the present study investigated whether the stress typicality effect modulated word recognition in native speakers of Chinese who learned English as a second language. Both visual grammatical classification and lexical decision tasks were administered to ESL learners with intermediate and advanced English proficiency. The results revealed that Chinese intermediate ESL learners were not sensitive to stress typicality in English; however, the advanced learners were. The findings suggest that different performances in stress assignment among Chinese ESL learners were influenced by their English proficiency levels.     

Building literacy in alphabetic, abjad and morphosyllabic systems

Preschoolers?? metalinguistic and visual capabilities may be associated with the writing system of their culture. We examined patterns of performance in phonological awareness, naming of letters, morphological awareness, and visual-spatial relations, in 5-year-old native speakers of Spanish (n?=?43), Hebrew (n?=?40), and Cantonese (n?=?63) and the relations of these literacy related skills to concurrent word writing and word reading. The writing systems in these languages represent three major categories, i.e., alphabetic (Spanish), abjad (Hebrew), and morphosyllabic (Chinese). Phonological awareness, letter naming, and perception of visual-spatial relations differed across groups, whereas morphological awareness showed a similar level of attainment in all three languages. Stepwise regression analyses explaining writing and reading for each language separately revealed both commonalities and differences between languages. Phonological awareness assessed by initial syllable deletion contributed to writing and to reading in Cantonese and in Spanish. Phonological awareness assessed by final phoneme isolation explained reading in Hebrew, whereas final and initial phoneme isolation explained writing in Hebrew. Letter naming predicted both writing and reading in Spanish and in Hebrew, while perception of visual-spatial relations did so in Cantonese. At age 5, children??s metalinguistic knowledge and visual discrimination abilities are already attuned to the particular features of the writing system to which they are exposed.
