Genetic and Environmental Links Between Natural Language Use and Cognitive Ability in Toddlers

Although the phenotypic correlation between language and nonverbal cognitive ability is well‐documented, studies examining the etiology of the covariance between these abilities are scant, particularly in very young children. The goal of this study was to address this gap in the literature by examining the genetic and environmental links between language use, assessed through conversational language samples, and nonverbal cognition in a sample of 3‐year‐old twins (N = 281 pairs). Significant genetic and nonshared environmental influences were found for nonverbal cognitive ability and language measures, including mean length of utterance and number of different words, as well as significant genetic covariance between cognitive ability and both language measures.     

Multidimensional ability tests and culturally and linguistically diverse students: Evidence of measurement invariance

Ability tests are used by teachers to provide additional context for interpreting student achievement and as a tool for differentiating instruction to the cognitive strengths and weaknesses of students. Tests that provide the most useful information for these purposes measure school-related content domains including verbal and quantitative reasoning. However, there is concern that verbal content affects validity for culturally and linguistically diverse students. In this study, the structure of a multidimensional ability test of verbal, quantitative, and nonverbal reasoning skills was explored in three groups of students who varied in language and cultural background. Configural invariance and invariant factor loadings were supported, but the verbal battery showed weaker relationships to the other batteries and reduced variability for English learners. Results indicate that battery-level scores are appropriate for all students, but that accounting for educational opportunity may be required for interpreting scores.     

Cognitive development in bilingual and monolingual lower-class children

The cognitive development of lower-class English-speaking monolingual and English-Spanishs peaking bilingual children in kindergarten, third, and sixth grades was compared by means of standard verbal and nonverbal measures. The verbal ability of bilingual children was assessed in both English and Spanish. Their scores in both languages were lower than those of monolingual children. However, the mean scores and error patterns of both groups on nonverbal measures were equivalent, suggesting that bilingual and monolingual children have comparable cognitive skills despite apparent language differences.     

Genetic and environmental mediation of the prediction from preschool language and nonverbal ability to 7‐year reading

We use a genetically sensitive design to examine the relationship between language and nonverbal ability at 4½ and reading skills at 7 years of age in a sample of more than 1,000 children participating in the Twins Early Development Study. We find that nonphonological as well as phonological measures of early language make significant contributions towards the prediction of reading at 7, and that nonverbal ability at 4½ is an equally strong predictor. With respect to aetiology, we find substantial genetic contributions towards the relationship between early language skills and reading at 7, as well as a trend towards shared environmental influences. The genetic continuity is not specific to the verbal domain, however, as we also find a substantial genetic relationship between nonverbal ability at 4½ and reading at 7.     

Literacy skills in children and adolescents with Down syndrome

Research has found that many children andadolescents with Down syndrome acquire somelevel of reading ability. Studies to date havedocumented that cognition, language, andphonological awareness contribute tovariability observed in performance onconventional literacy measures for thispopulation, although the extent of relativecontributions varies among studies. Less isknown about the relationship of early literacyskills to conventional reading, or howrelationships among variables that supportliteracy acquisition are similar or differentfrom those observed in typically developingchildren. In this project, cognition,language, early literacy, phonologicalawareness and reading skills were examined in agroup of children and adolescents with Downsyndrome (aged 5;06 to 17;03) and a group oftypically developing children (aged 3;06 to5;03) matched for nonverbal cognition. Resultsrevealed broad variability in performance onearly literacy and reading measures in personswith Down syndrome. Comparisons with mental age-matchedchildren indicated differences in the relativecontribution of language and cognition toreading ability, with language being a strongerpredictor in the group with Down syndrome.     

Communication competence in reading and learning disabilities

Conclusion The evidence indicates that learning-disabled children show pervasive and enduring language problems across a wide variety of language tasks. The studies suggest that the problems experienced by learning and reading-disabled children may fall into the categories of phonology, syntax, semantics, and pragmatics as well as nonverbal communication. In terms of nonverbal communication, these children are less accurate in interpreting nonverbal auditory and visual cues. In phonology, it appears that they are less skilled in detecting the segments of single words and thus have difficulty establishing phoneme to grapheme correspondence. In the area of syntax, learning-disabled males are less skilled in dealing with inflection and the comprehension and creation of complex sentences. In semantics, they are less adequate than nondisabled children in defining words, creating sentences, and classifying objects into categories. They show less adequate sentence production, are less skilled at recognizing their errors, and are significantly slower in generating verbal responses. Finally, there is one study that suggests that learning-disabled children may be discriminated by their use of language in social situations. This paper was presented at the 29th Annual Conference of The Orton Society at Minneapolis, November, 1978.     

Concurrent correlates and predictors of reading and spelling achievement in deaf and hearing school children

Seven- and eight-year-old deaf children and hearing children of equivalent reading age were presented with a number of tasks designed to assess reading, spelling, productive vocabulary, speechreading, phonological awareness, short-term memory, and nonverbal intelligence. The two groups were compared for similarities and differences in the levels of performance and in the predictors of literacy. Multiple regressions showed that both productive vocabulary and speechreading were significant predictors of reading for the deaf children after hearing loss and nonverbal intelligence had been accounted for. However, spelling ability was not associated with any of the other measures apart from reading. For hearing children, age was the main determinant of reading and spelling ability (due to selection criterion). Possible explanations for the role of speechreading and productive vocabulary in deaf children's reading and the differences between the correlates of literacy for deaf and hearing children are discussed.     

Nonverbal Ability and Scientific Vocabulary Predict Children's Causal Reasoning in Science Better than Generic Language

Verbal and nonverbal forms of thinking exhibit widespread dissociation at neural and behavioral level. The importance of this for children's causal thinking and its implications for school science are largely unknown. Assessing 5‐ to 10‐year‐olds' responses (N = 231), verbal ability predicted causal reasoning, but only at lower levels, while nonverbal ability was the strongest predictor at higher levels of causal inference. We also distinguished between generic and scientific vocabulary use (n = 101). The results showed that use of scientific vocabulary predicted causal reasoning beyond generic, and connected more to nonverbal thinking. The findings highlighted the importance of elementary school science activities supporting application of nonverbal ability in thinking about causal processes; the benefits of linking nonverbal imagery to scientific vocabulary; and shortcomings in understanding of the forms/sources of nonverbal ability and their role in learning.     

Personalizing e-Learning. The Social Effects of Pedagogical Agents

Numerous studies have evaluated the effects of pedagogical agents on students’ learning outcomes, but so far, beneficial effects have not been consistently demonstrated. The ambiguous results might partly be due to the strong emphasis on cognitive outcomes, which is characteristic for research in teaching and learning. The paper suggests a shift of attention to socio-emotional and relational variables, which might be considered as relevant moderator variables in learning or even as learning outcomes per se, for example, in social learning. In order to achieve this goal, we suggest a systematic account of the results from social psychology and in particular from nonverbal communication research, and findings from studies on the social effects of embodied agents in general. This perspective will include (1) a distinction between static and dynamic aspects of embodiment, such as the visual appearance of agents and their nonverbal behavior, and (2) a more systematic approach concerning the functions of embodiment and nonverbal behavior, such as modeling, discourse and dialogue functions, and socio-emotional effects. A further argument addresses the necessity of complementing outcome measures by process measures, which are sensitive to the tasks and the changing situational demands that occur during learning processes and tutor-learner interaction.     

Preschool Verbal and Nonverbal Ability Mediate the Association Between Socioeconomic Status and School Performance

We compared the extent to which the long-term influence of family socioeconomic status (SES) on children's school performance from age 7 through 16 years was mediated by their preschool verbal and nonverbal ability. In 661 British children, who completed 17 researcher-administered ability tests at age 4.5 years, SES correlated more strongly with verbal than nonverbal ability (.39 vs. .26). Verbal ability mediated about half of the association between SES and school performance at age 7, while nonverbal ability accounted for a third of the link. Only SES, but not verbal or nonverbal ability, was associated with changes in school performance from age 7 to 16. We found that SES-related differences in school performance are only partly transmitted through children's preschool verbal abilities.     

Assessing early arithmetic abilities: Effects of verbal and nonverbal response types on the calculation performance of middle-and low-income children

In two studies, we compared young children's performance on three variations of a nonverbally presented calculation task. The experimental tasks used the same nonverbal mode of presentation but were varied according to response type: (1) putting out disks (nonverbal production); (2) choosing the correct number of disks from a multiple-choice array (nonverbal recognition); and (3) giving a number word (verbal production). The verbal production task required children to map numerosities onto the conventional number system while the nonverbal production and nonverbal recognition tasks did not. Study 1 showed that the performance of 3-, 4- and 5-year-old middle-income children (N = 72) did not vary with the type of response required. Children's answers to nonverbally presented addition and subtraction problems were available in both verbal and nonverbal forms. In contrast. Study 2 showed that low-income children (3- and 4-year-olds; N = 48) performed significantly better on both nonverbal response type tasks than on the verbal response type task. Analysis of individual data indicated that a number of the low-income children were successful on the completely nonverbal calculation tasks, even though they had difficulty with verbal counting (i.e., set enumeration and cardinality). The findings suggest that the ability to calculate does not depend on mastery of conventional symbols of arithmetic.     

Dyslexic,delayed, precocious or just normal? Word reading skills of children with autism spectrum disorders

Word reading skills and reading‐related language and cognitive correlates were examined in Swedish 10–15‐year‐olds with autism spectrum disorders (ASD). The full group with ASD did not differ statistically from an age‐matched comparison group in word reading, but a poor‐readers subgroup was identified who displayed severe difficulties. Normal readers with ASD did not differ from the comparison group in nonverbal ability, phonological processing, rapid naming or receptive vocabulary. The poor subgroup performed, however, below on all measures except nonverbal ability. When poor readers with ASD were matched for reading level with younger controls, no difference was found on any reading‐related skill. No significant correlation was furthermore found between autistic symptomatology and word reading within the ASD group. It is concluded that the pattern of individual differences in word reading among children with ASD conforms well to that seen in children without ASD of normal or delayed reading abilities.     

Results of the study

This chapter presents and discusses the results of the study. The results are presented in three sections: results of the correlational analysis, results of the regression analysis, and results of the path analysis. In general the results suggest that family background is indirectly linked to GPA by virtue of its direct effect on study behaviors, verbal ability, and nonverbal ability. Similarly, the link between study behaviors and GPA is mediated through verbal ability and nonverbal ability. Family background and study behaviours consistently predicted nonverbal ability, verbal ability, and GPA, even after the effects of the other cognitive variables had been removed.     

Decoding Ability and Humor Production

Scholars have suggested that being “in tune” with others may be an important aspect of successful humor creation; however, few studies have specifically investigated this possibility. Thus, this study examined the relationship between decoding ability and humor orientation. Decoding ability was conceptualized as involving three communication constructs: conversational sensitivity, nonverbal sensitivity, and receiver apprehension. Consistent with predictions, results revealed positive relationships between (1) humor orientation and conversational sensitivity and (2) humor orientation and nonverbal sensitivity. Also consistent with predictions, a negative relationship was found between humor orientation and receiver apprehension. Further analysis indicated the three communication variables together accounted for 24% of the variance in humor orientation; only conversational sensitivity and receiver apprehension, however, accounted for unique variance. Overall, these findings suggest humor production may be related to the ways in which individuals attend to their social environments.     

Effects of brain laterality on accuracy of decoding facial displays of emotion

The human face is capable of producing numerous unique expressions and comprises the primary nonverbal channel for the communication of emotion. In this study, we investigated the effects of sex and neurological hemispheric dominance on the ability to decode facial expressions of emotion accurately. On the basis of a battery of measures assessing handedness, familial sinistrality, and immune disorders, we classified participants as having standard, anomalous, or mixed hemispheric dominance. Consistent with previous studies, we found that hemispheric dominance and sex interacted to influence participants' abilities to decode facial displays of affect from photographs. Specifically, mixed dominant females had the highest accuracy in the decoding of facial emotion, whereas mixed dominant males had the lowest accuracy. We discuss these findings within the context of communibiology and comment on their implications for the study of neurology and social behavior.     

Assessing the cognitive abilities of culturally and linguistically diverse students: Predictive validity of verbal,quantitative, and nonverbal tests

Verbal and quantitative reasoning tests provide valuable information about cognitive abilities that are important to academic success. Information about these abilities may be particularly valuable to teachers of students who are English‐language learners (ELL), because leveraging reasoning skills to support comprehension is a critical aptitude for their academic success. However, due to concerns about cultural bias, many researchers advise exclusive use of nonverbal tests with ELL students despite a lack of evidence that nonverbal tests provide greater validity for these students. In this study, a test measuring verbal, quantitative, and nonverbal reasoning was administered to a culturally and linguistically diverse sample of students. The two‐year predictive relationship between ability and achievement scores revealed that nonverbal scores had weaker correlations with future achievement than did quantitative and verbal reasoning ability scores for ELL and non‐ELL students. Results do not indicate differential prediction and do not support the exclusive use of nonverbal tests for ELL students. © 2012 Wiley Periodicals, Inc.     

Genetic influences on specific versus nonspecific language impairment in 4-year-old twins

The present study addresses the distinction between specific (SLI) and nonspecific (NLI) language impairment at an etiological level by estimating the relative genetic and environmental contributions to language impairment in children with SLI and NLI. Drawing on a large longitudinal twin study, we tested a sample of 356 four-and-a-half-year-old children with low language ability and their twin partners at home on a range of language and nonverbal measures. For children whose language and nonverbal abilities were both low (NLI), genetic influence on language impairment was moderate and shared environmental influence was substantial. A similar pattern emerged for children whose language difficulties occurred in apparent isolation (SLI), although there was a trend for the genetic effects to be smaller for SLI than for NLI: Group heritability was .18 for SLI and .52 for NLI. Probandwise cross-concordances were suggestive of some genetic overlap between these two groups, but not with a subgroup of children with more severe cognitive delay.
