Clinical Sense and the Problem of Non-Verbal Intelligence Testing in Diagnosis and Training of Hearing and Speech Handicapped Children

To evaluate the association between adolescent and young-adult hearing loss and nonverbal intelligence in rural Nepal. Cross-sectional assessment of hearing loss among a population cohort of adolescents and young adults. Sarlahi District, southern Nepal. Seven hundred sixty-four individuals aged 14 to 23 years. Evaluation of hearing loss, defined by World Health Organization criteria of pure-tone average greater than 25 decibels (0.5, 1, 2, 4 kHz), unilaterally and bilaterally. Nonverbal intelligence, as measured by the Test of Nonverbal Intelligence, 3rd Edition standardized score (mean, 100; standard deviation, 15). Nonverbal intelligence scores differed between participants with normal hearing and those with bilateral (p = 0.04) but not unilateral (p = 0.74) hearing loss. Demographic and socioeconomic factors including male sex; higher caste; literacy; education level; occupation reported as student; and ownership of a bicycle, watch, and latrine were strongly associated with higher nonverbal intelligence scores (all p < 0.001). Subjects with bilateral hearing loss scored an average of 3.16 points lower (95% confidence interval, -5.56 to -0.75; p = 0.01) than subjects with normal hearing after controlling for socioeconomic factors. There was no difference in nonverbal intelligence score based on unilateral hearing loss (0.97; 95% confidence interval, -1.67 to 3.61; p = 0.47). Nonverbal intelligence is adversely affected by bilateral hearing loss even at mild hearing loss levels. Socio economic well-being appears compromised in individuals with lower nonverbal intelligence test scores.

To examine the influence of speech perception, cognition, and implicit phonological learning on articulation skills of children with velocardiofacial syndrome (VCFS) and children with cleft palate or velopharyngeal dysfunction (VPD). Cross-sectional group experimental design. Eight children with VCFS and five children with nonsyndromic cleft palate or VPD. All children participated in a phonetic inventory task, speech perception task, implicit priming nonword repetition task, conversational sample, nonverbal intelligence test, and hearing screening. Speech tasks were scored for percentage of phonemes correctly produced. Group differences and relations among measures were examined using nonparametric statistics. Children in the VCFS group demonstrated significantly poorer articulation skills and lower standard scores of nonverbal intelligence compared with the children with cleft palate or VPD. There were no significant group differences in speech perception skills. For the implicit priming task, both groups of children were more accurate in producing primed nonwords than unprimed nonwords. Nonverbal intelligence and severity of velopharyngeal inadequacy for speech were correlated with articulation skills. In this study, children with VCFS had poorer articulation skills compared with children with cleft palate or VPD. Articulation difficulties seen in the children with VCFS did not appear to be associated with speech perception skills or the ability to learn new phonological representations. Future research should continue to examine relationships between articulation, cognition, and velopharyngeal dysfunction in a larger sample of children with cleft palate and VCFS.

The Wechsler Adult Intelligence Scale, Otis Mental Ability Test, Advanced Progressive Matrices, Revised Beta Examination, the D 48 Test, and the Minnesota Paper Form Board were administered to 131 college students to determine the intercorrelations among nonverbal and verbal tests of intelligence. The obtained coefficients were corrected for restriction of range on the WAIS IQs. Between Progressive Matrices and the WAIS Full Scale IQ r = .74 and for the Matrices and the Otis IQ r = .75. The other nonverbal tests showed a low to moderate relationship with the IQ scores.

In order to examine the relationship between linguistic background and nonverbal intelligence, two groups of Canadian native children, one bilingual and the other monolingual, were administered tests of verbal ability and nonverbal intelligence. The bilingual group was found superior on a test of nonverbal intelligence, however, no difference was obtained between the groups with respect to English vocabulary level. The results are interpreted as showing general support for a transfer-accretion model for the development of intelligence and abilities.

The assessment of intelligence in Autistic Spectrum Disorder (ASD) has been gaining ground in scientific research, indicating a tendency to intellectually superior results, with high IQ, when evaluated by non-verbal intelligence tests. This study evaluated the intelligence of 30 children aged between 5 years and 11 years and 9 months, diagnosed with ASD, mild and moderate degree, using non-verbal intelligence tests, Raven's Colored Progressive Matrices and the Non-Verbal Test of Intelligence for Children (R-2), aiming to expand studies related to the assessment of the intelligence of children with ASD and to check among the standardized instruments available in Brazil, the most appropriate. The data were analyzed in a standardized way, evaluating the percentile and standard score (IQ) of the sample, according to the rules of each test, and the results showed intelligence within the mean in Raven and upper mean in R-2, reinforcing previous studies. The scores were analyzed using Pearson's coefficient, showing high correlation and convergence between the tests (coefficient r = 0.89) crediting the R-2 as a potential psychometric instrument in the assessment of this target audience. Researches like this can increase the knowledge about the intelligence construct in ASD and guide the choice of non-verbal tests, as favorable instruments in the intelligence assessment of this target audience.

Academic achievement, measured with the grade point average (GPA), is a stable characteristic that has been associated with many sociodemographic and psychological variables; however, the relation of these variables with GPA has not been totally elucidated. The objective of this study was to perform an association of health, psychological and personal variables with GPA and non-verbal intelligence in low-academic performance population according to sex. We invited health sciences university students who had failed the same subject twice to complete a set of sociodemographic and psychological variables and a non-verbal intelligence test. The GPA, admission exam test and preparatory GPA were obtained. We included 124 students, and found that GPA was associated with non-verbal intelligence in women but not in men; in whom, having a job and having a romantic partner, were more correlated. In women, positive relations with others, emotion perception and weekly physical activity hours were marginally correlated with GPA; while in men, emotion regulation and self-motivation had a tendency of correlation with GPA. In addition, we found that non-verbal intelligence was associated somatization and the number of diseases in women. Academic achievement is regulated by different variables in each sex; therefore, intervention programs addressed by sex are needed to increase it.

Objectives: Phonological awareness is the ability to recognize and manipulate the sound structure of spoken words and shows a strong relationship with early literacy. Children's development of phonological awareness is affected by speech-language skills, intelligence, and environmental factors. This study aims to examine the relationship between phonological awareness and related factors; including speech-language skills, nonverbal intelligence, and social-economic status (SES) in 1st to 3rd graders and to identify which factors significantly predict phonological awareness. Methods: A total of 128 1st to 3rd-grade students received a phonological awareness test, articulation and phonology test, receptive and expressive vocabulary tests, and nonverbal intelligence test. Information about the SES for each child was also obtained. Correlation analysis and stepwise multiple regressions were performed to examine which factors predict phonological awareness at the syllable and phoneme levels among articulation and phonology ability, receptive and expressive vocabulary, nonverbal intelligence, SES and grades. Results: The results indicated that receptive vocabulary and articulation, and phonology ability predict significantly phonological awareness at the syllable level. Also, expressive vocabulary and nonverbal intelligence significantly predict phonological awareness at the phoneme level. Conclusion: This study suggests that phonological awareness develops during the early primary school years, and shows close relationships with receptive and expressive vocabulary, articulation and phonology ability, and intelligence.

The primary aim of the study was to measure the receptive and expressive vocabulary with respect to clinical parameters and selected socio-demographic variables and to assess whether the size of vocabulary could be predicted by certain variables in a consecutive series of children identified as having bilateral sensorineural hearing loss ("Göttinger Hör-Sprachregister"). All children aged between 2;6 to 6;3 years diagnosed in the Department of Phoniatrics/Pedaudiology of the University Göttingen as having a permanent bilateral sensorineural hearing impairment ("Göttinger Hör-Sprachregister") in a defined period (july 1995-september 2000) were examined with standardized receptive and expressive vocabulary tests as well as a nonverbal intelligence test (on average 5.5 months after diagnosis and 2.9 months after fitting with hearing aids). 37 children (20 boys, 17 girls). Mean age at diagnosis: 48.5 (SD 15.9; min. 18, max. 75) months, mean age at hearing aid fitting: 51 months (SD 15.2). Multiple handicapped children, children with additional conductive hearing impairment and those with postnatal losses were excluded. The sample as a whole demonstrated lexical deficits of varying severity that were greater in the expressive than in the receptive vocabulary, depending on the clinical parameter. Children with congenital hearing impairment, with severe-to-profound hearing impairment (> 70 dB) and bilingual children demonstrated on average the smallest receptive and expressive vocabulary. An early fitting with hearing aids did not correspond with a better lexical development when a severe-to-profound hearing impairment existed. Severity of a hearing impairment and nonverbal intelligence significantly predicted the average size of the receptive vocabulary. A moderate hearing impairment, high non-verbal intelligence, and gender (female) emerged as the strongest significant predictors of the expressive vocabulary. The vocabulary test result of a bilateral sensorineurally hearing-impaired child may be an indicator for early cognitive training.

The paper explores why certain adults are, or at least consider themselves to be, more ironic than others. The study looked at comprehension and application of irony compared to subjective affective evaluation of irony reported by Polish-speaking adults and with relation to nonverbal intelligence measured with the Wechsler Adult Intelligence Scale-Revised-Polish versions (WAIS-R(PL), 2004). Fifty-four subjects aged 20-66 years (28 females and 26 males) participated in Study 1 on subjective perception of irony. The comprehension, emotional valence and social functions of ironic meanings as well as the degree to which subjects perceived themselves as ironic were assessed through a self-report questionnaire. Inter-correlations were performed and related to the performance quotient (IQ) which was measured in Study 2, where 45 (24 females and 21 males) out of the 54 participants were tested with performance subtests of the Wechsler Adult Intelligence Scale-Revised-Polish versions (WAIS-R(PL), 2004). The nonverbal intelligence scale was administered. Performance on nonverbal intelligence tests is not limited by language abilities and its analysis and can be considered important for future cultural comparative studies. Subjects who perceived themselves as ironic showed a higher nonverbal IQ in comparison to subjects who described themselves as non-ironic or barely ironic. The pragmatic qualities of irony were analyzed for their affective valuation and balanced for gender. Individual differences and gender effects in the perception of the social functions of ironic utterances were found. The paper describes the implicit emotional layer conveyed in irony and its importance in irony processing and comprehension.

Although there has been considerable research on the interplay between intelligence and second language (L2) learning, research focusing on the intelligence and L2 speech perception link is limited. The present study aims to fill this gap. The native language of the participants was Cypriot Greek and they spoke English as an L2. The participants completed a forced-choice psychoacoustic test in which they discriminated L2 sound contrasts and a nonverbal intelligence test which measured their nonverbal intelligence capacities. They were divided into two groups according to their performance in the intelligence test, namely, a low IQ and a high IQ group. The results showed that the high IQ group discriminated the majority of the L2 contrasts better than the low IQ group. In addition, the degree of perceived difficulty for most L2 contrasts differed between the two groups. It is concluded that nonverbal intelligence is associated with the discrimination of L2 sounds. This can be explained by the possibility that either intelligence triggers the more efficient functioning of other domains, such as information processing and attention, leading to increased speech perception skills, or that it directly affects the categorization of speech sounds resulting in the development of more robust L2 categories.

Although extensive research has focused on the perceptual abilities of second language (L2) learners, a significant gap persists in understanding how cognitive functions like phonological short-term memory (PSTM) and nonverbal intelligence (IQ) impact L2 speech perception. This study sets out to investigate the discrimination of L2 English monophthongal vowel contrasts and to assess the effect of PSTM and nonverbal IQ on L2 speech perception. The participants consisted of adult monolingually-raised Greek speakers, who completed an AX discrimination test, a digit span test, and a nonverbal intelligence test. A control group of English speakers also completed the AX test. Data were analyzed using Bayesian regression models. The results revealed that Greek speakers exhibited below chance discrimination for the majority of L2 vowel contrasts, consistently underperforming in comparison to the control group. Intriguingly, the study did not provide substantial evidence in favor of more accurate discrimination of L2 contrasts by Greek participants with high PSTM compared to those with low PSTM. However, the study yielded compelling evidence indicating that Greek participants with higher IQ demonstrated superior accuracy in discriminating most L2 contrasts compared to their lower IQ counterparts. The limited influence of PSTM on speech perception suggests the need for further exploration, considering the potential impact of test methodologies and the intricate interplay of other confounding factors. Furthermore, the study uncovers a noteworthy relationship between nonverbal IQ and L2 speech perception, likely linked with the association of high IQ with enhanced attentional capacities, information processing abilities, and learning skills—all of which are pivotal for accurate speech perception.

The Test of Nonverbal Intelligence (TONI) and Wechsler Intelligence Scale for Children--Revised (WISC--R) were administered to 46 Native American and white students who were suspected by their classroom teachers of having learning handicaps. Pearson correlations between these sets of IQs ranged from .42 (TONI and WISC--R Performance) to .89 (WISC--R Verbal and Full Scale).
