Innateness and maturation in linguistic development.

Language is species-specific, species-wide, and highly structured. Its principles (Universal Grammar) are innate (genetically determined) in the child, although some linguistic capacity is subject to a maturational schedule, examples of which are given. Some particular aspects of language are learned, in a way driven by Universal Grammar. However, empiricist "learning theories" of all types are far too weak to be useful in explaining either the final adult language or the precise timing of developmental processes. The assumption of Universal Grammar is, in fact, crucial in explaining what kind of learning actually takes place.

Linguistic analysis of chromosome III DNA sequence of Saccharomyces cerevisiae.

The analysis of the Saccharomyces cerevisiae chromosome III DNA sequence by computer ('in silico') permits the definition of its linguistic characteristics. These characteristics include the designation of non-randomly occurring oligonucleotides, their distribution along the chromosome, and the distribution of some particular homopolymers. All these elements may contribute to the understanding of the organization of information on the chromosome.

The role of morphological structure in the processing of compounds: the interface between linguistics and psycholinguistics.

This study presents a cross-linguistic investigation of lexical access and subjects' sensitivity to the internal morphological structure of compounds in two highly inflected languages, Greek and Polish. The following questions were addressed: Are individual constituents activated during on-line word recognition? To what extent does internal morphological structure play a role during lexical access? Is there an interaction between headedness and constituent-priming given that the inflection that the second constituent carries determines the gender, number, and case of the compound? Our results show activation of individual constituents of compounds during priming, a strong word effect, and a positional advantage for first constituents in spite of the presence of second constituent heads.

Social validity of changes in informativeness and efficiency of aphasic discourse following linguistic specific treatment (LST).

This study presents the results of an analysis of pragmatic aspects of language samples obtained from five agrammatic aphasic individuals prior to and following Linguistic Specific Treatment (LST). Clinically and statistically significant positive changes in informativeness and efficiency were documented in posttreatment samples. Analysis of communicative competence (i.e., naïve listeners' ratings of pre- and posttreatment audiotaped samples), was undertaken to examine the social validity of quantified changes. Mean ratings across listeners were computed to evaluate their subjective perceptions of general communicative constructs. Results indicated that objectively measured changes in pragmatic aspects were perceptible to naïve listeners, however, to varying degrees across participants and constructs.

Cross-linguistic contrasts of verification and answering among children.

This review article examines how children verify a statement (e.g., You are a child. Right or wrong?) and answer a corresponding question (e.g., Are you a child? Yes or no?) in English, French, Japanese, and Korean. While people verify affirmative statements and answer affirmative questions similarly across the four languages, they answer negative questions differently across the four languages. In English, answering negative questions works in a way opposite to verification (e.g., Are you not a child? Yes; You are not a child. Wrong). In French, si is used in the place of the yes response in English. In Japanese and Korean, answering negative questions works in a way similar to verification (e.g., Are you not a child? No; You are not a child. Wrong). The effects of these linguistic characteristics are examined. Findings are: (1) All children across the four languages appear to start answering negative questions using the English system; (2) English-speaking children find verifying negative statements more difficult than answering the corresponding questions but Japanese-speaking children find it less difficult; and (3) while English-speaking and Korean-speaking children find true negative statements more difficult to verify than false negative statements, Japanese-speaking children find them less difficult. Language-universal and language-specific processes in verification and answering are discussed.

Linguistic negation in autistic and normal children.

Young, severely maladaptive autistic children with some speech competence were compared to normally developing 3-year-old children of lower and middle class and 5-year-olds of lower class on negation tasks. All subjects were shown 12 sets of cards depicting negative contrasts designed to elicit semantic categories of nonexistence, denial, and rejection and were tested for production, imitation, and comprehension. Syntactic and semantic analysis revealed that autistic children were superior imitators and poor producers but showed skills in comprehension comparable to a 4-year-old's level of functioning. While retarded in some functions, the experimental group produced syntactic structures that were more rigid, suggesting the significantly greater use of imitation as a major strategy in linguistic coding.

On the nature of linguistic functioning in early infantile autism.

This paper provides a review of studies conducted on linguistic functioning in autistic children, within the framework developed in normal language acquisition research. Despite certain methodological weaknesses, the research consistently shows that phonological and syntactic development follow the same course as in normal children and in other disordered groups, though at a slowed rate, while semantic and pragmatic functioning may be specially deficient in autism. These findings are related to other recent studies on the relative independence of different aspects of language.

The pre-linguistic autism diagnostic observation schedule.

The Pre-Linguistic Autism Diagnostic Observation Schedule (PL-ADOS) is a semistructured observation scale designed for use as a diagnostic tool for children less than 6 years old who are not yet using phrase speech and are suspected of having autism. The PL-ADOS takes approximately 30 minutes to administer and is appropriate for use with this population because of its emphasis on playful interactions and the use of toys designed for young children. Reliability studies indicated that both individual activity ratings and summary ratings could be reliably scored from videotaped assessments by naive raters. Additionally, PL-ADOS scores of nonverbal preschool-aged children referred for clinical diagnosis and classified on the basis of a diagnostic team's clinical judgment, clearly discriminated between autistic and nonautistic developmentally disabled children. The resulting diagnostic algorithm is theoretically linked to diagnostic constructs associated with ICD-10 and DSM-IV criteria for autism.

The effects of two levels of linguistic constraint on echolalia and generative language production in children with autism.

The effects of specific types of adult antecedent utterances (high vs. low constraint) on the verbal behaviors produced by three subjects with autism were examined. Adult utterance types were differentiated in terms of the amount of control the adults exhibited in their verbal interactions with the subjects during a free play setting. Videotaped interactions were analyzed and coded according to a predetermined categorical system. The results of this investigation suggest that the level of linguistic constraint exerted on the child interactants during naturalistic play sessions affected their communicative output. The overall findings suggest that (a) adult high constraint utterances elicited more verbal utterances in general, as well as a majority of the subjects' echolalia; (b) adult low constraint utterances elicited more subject high constraint utterances; and (c) the degree of constraint of adult utterances did not appear to influence the mean lengths of subjects' utterances. The results are discussed in terms of their implications for educational interventions, and suggestions are made for future research concerning the dynamics of echolalia in interactive contexts.

Objectively defined linguistic parameters in children with autism and other developmental disabilities.

The language of children with autism and other developmental disabilities was examined systematically according to a set of objectively defined linguistic parameters. These criteria were drawn from clinical observations reported in the literature and from developmental norms of language acquisition. Data analysis identified sets of parameters that were correlated with psychiatrists' clinical diagnoses but failed to isolate individual parameters (such as echolalia or noncommunicativeness) that have been suggested to be pathonomic.

How is linguistic memory accessed? A psychophysiological approach.

The role of "subvocalization" during language comprehension, especially reading, is examined. Four arguments against it having a role in accessing memory are erroneous because 1) its latency is much shorter than is conventionally stated; 2) rate of visual information processing is erroneously estimated by failing to distinguish between reading and scanning; 3) covert speech does not disappear in the competent language performer; and 4) the argument that subvocalization is an epiphenomenon is irrelevant. Rather, data support the generalization that covert speech is present during all cognitive functioning and that its specific topography is discriminatively related to the class of phoneme being processed. It is thus inferred that during cognition the speech musculature generates a phonetic code that may function to access linguistic memory. However, since there are also numerous other psychophysiologic events associated with covert speech, a multichannel processing system is hypothesized wherein speech, visual, and kinesthetic modalities interact with the brain. Illustrations are given of how this accessing model is compatible with existing holographic and feature analyzer models of memory. Data are presented that illustrate how phonetically encoded neuromuscular events can be directly measured through psychophysiologic methods. It is hypothesized that cognitive processes are generated when cybernetic neuromuscular circuits selectively interact. Consequently, all components of these neuromuscular circuits serve a function during cognition so that a role for "subvocalization" (a muscular component) cannot be ruled out in an apriori manner.

The Babel effect: community linguistic diversity and extramarital sex in Uganda.

We examine the association of community linguistic diversity with non-spousal sexual activity in Uganda. We conducted a survey on rates of sexual contact in last 12 months among 1709 respondents age 18-60 living in Uganda in early 2001. Households were selected at random from Demographic and Health Survey (DHS) 2000 household sampling frame listings in 12 districts and 120 clusters. Household listings described the principal language spoken by every household in the cluster. Sexual contact was reported by 26 vs. 13% of unmarried women in multilingual vs. monolingual clusters respectively. Extramarital sexual contact occurred for 29 vs. 16% for married men in multilingual vs. monolingual clusters respectively. These results were robust to multivariate models which included confounders such as urbanity, and cluster distance to market places, cinemas, and transportation. Our results suggest a robust association between residence in a multilinguistic community and higher rates of non-spousal sex.

Sexual desire and linguistic analysis: a comparison of sexually-abused and non-abused women.

Although studies have identified a relationship between a history of child sexual abuse (CSA) and problems with hypoactive sexual desire, little is known about the potential cognitive and affective mechanisms involved in the sexual desire of women with a history of CSA. In this study, 27 women with a history of CSA and 22 women with no history of abuse were asked to write about sexual and non sexual topics. The Linguistic Inquiry Word Count software program was used to compute the percentage of words that fell into positive emotions, negative emotions, body, and sex categories. As expected, women with a history of CSA used more negative emotions words when writing about sexual topics, but not non-sexual topics, compared to non-abused women. Women with a history of CSA also used more sex words when writing about the non-sexual topics compared to non-abused women. Frequencies of body and sex words used in the sexual texts were positively linked to levels of sexual desire function. This association was not different between women with and without a history of CSA. A history of CSA remained an independent predictor of levels of sexual desire dysfunction even when taking into consideration the language used in the sexual texts, indicating that there may be aspects of the sexual desire experienced by women with a history of CSA that differ from non-abused women that remain unexplored.

'Nobody can help me...i am living through it alone': experiences of caring for people diagnosed with mental illness in ethno-cultural and linguistic minority communities.

Caregivers of people diagnosed with mental illness in ethno-cultural and linguistic minority communities (ECLMCs) face considerable demands and difficulties in their day-to-day caring role. Data from interviews with 20 caregivers from Polish, Croatian, Bosnian, and Chinese communities, undertaken in Perth, Western Australia, explore the roles caregivers play in the lives of their relatives and illustrate their use and non-use of support services. A diverse array of challenges confronts caregivers across the different ECLMCs. Although not an unequivocally negative experience, caring for a relative diagnosed with mental illness was found to frequently disrupt family relationships and to lead to physical and mental exhaustion as well as social isolation. The stigma associated with mental illness in ECLMCs is a significant factor dissuading people from seeking assistance from external agencies. Many mainstream services are seen as inappropriate, which appears to be a factor in their under-utilization. If mental health policies and community services are to seriously address the issue of appropriate support for caregivers from ECLMCs, it is important that they are aware of the nature of the considerable demands placed on such caregivers as they endeavor to support their dependent relatives.

A cross-linguistic speech error investigation of functional complexity.

This work is a systematic, cross-linguistic examination of speech errors in English, Hindi, Japanese, Spanish and Turkish. It first describes a methodology for the generation of parallel corpora of error data, then uses these data to examine three general hypotheses about the relationship between language structure and the speech production system. All of the following hypotheses were supported by the data. Languages are equally complex. No overall differences were found in the numbers of errors made by speakers of the five languages in the study. Languages are processed in similar ways. English-based generalizations about language production were tested to see to what extent they would hold true across languages. It was found that, to a large degree, languages follow similar patterns. However, the relative numbers of phonological anticipations and perseverations in other languages did not follow the English pattern. Languages differ in that speech errors tend to cluster around loci of complexity within each language. Languages such as Turkish and Spanish, which have more inflectional morphology, exhibit more errors involving inflected forms, while languages such as Japanese, with rich systems of closed-class forms, tend to have more errors involving closed-class items.

Effects of linguistic redundancy and coded voice warnings on system response time.

Similar system response times have been reported for keyword and semantic context warning messages based on the premise that the linguistic redundancy of semantic context warnings require less attention than the shorter keyword warnings. The present study was conducted to learn whether an initial word of warning could be used for alerting purposes without increasing system response time and whether or not differences exist between the keyword and semantic conditions. Fifteen subjects were given a flying task using an IBM PC Flight Simulator package and responded to synthesised speech warnings under conditions of cockpit conversation, simulated noise and various flying duties. The keyword-only condition provided a statistically significant lower SRT than all other conditions but, with larger movement/reaction time, appeared to have placed the greatest cognitive demand on subjects. Recommendations are made on the implications regarding the use of the keyword-only format.

Cross-linguistic regularities in the frequency of number words.

We examine the frequency of numerals and ordinals in seven different languages and/or cultures. Many cross-cultural and cross-linguistic patterns are identified. The most striking is a decrease of frequency with numerical magnitude, with local increases for reference numerals such as 10, 12, 15, 20, 50 or 100. Four explanations are considered for this effect: sampling artifacts, notational regularities, environmental biases and psychological limitations on number representations. The psychological explanation, which appeals to a Fechnerian encoding of numerical magnitudes and to the existence of numerical points of reference, accounts for most of the data. Our finding also has practical importance since it reveals the frequent confound of two experimental variables: numerical magnitude and numeral frequency.

Linguistically based speechreading assessment.

A videotaped speechreading test, Eyes and Spoken Language, has been designed to assess how effectively a person utilizes linguistic constraints in responding to spoken language via the visual pathway. Concurrent validity and test-retest reliability has been established using responses of 68 non-hearing-impaired young adults. A significant learning effect has been demonstrated from one administration to another 2 wk later. The clinical implications of this finding are discussed.
