RESUMO

BACKGROUND: Articulatory excursion and vocal intensity are reduced in many children with dysarthria due to cerebral palsy (CP), contributing to the children's intelligibility deficits and negatively affecting their social participation. However, the effects of speech-treatment strategies for improving intelligibility in this population are understudied, especially for children who speak languages other than English. In a cueing study on English-speaking children with dysarthria, acoustic variables and intelligibility improved when the children were provided with cues aimed to increase articulatory excursion and vocal intensity. While French is among the top 20 most spoken languages in the world, dysarthria and its management in French-speaking children are virtually unexplored areas of research. Information gleaned from such research is critical for providing an evidence base on which to provide treatment. AIMS: To examine acoustic and perceptual changes in the speech of French-speaking children with dysarthria, who are provided with speech cues targeting greater articulatory excursion (French translation of 'speak with your big mouth') and vocal intensity (French translation of 'speak with your strong voice'). This study investigated whether, in response to the cues, the children would make acoustic changes and listeners would perceive the children's speech as more intelligible. METHODS & PROCEDURES: Eleven children with dysarthria due to CP (six girls, five boys; ages 4;11-17;0 years; eight with spastic CP, three with dyskinetic CP) repeated pre-recorded speech stimuli across three speaking conditions (habitual, 'big mouth' and 'strong voice'). Stimuli were sentences and contrastive words in phrases. Acoustic analyses were conducted. A total of 66 Belgian-French listeners transcribed the children's utterances orthographically and rated their ease of understanding on a visual analogue scale at sentence and word levels. OUTCOMES & RESULTS: Acoustic analyses revealed significantly longer duration in response to the big mouth cue at sentence level and in response to both the big mouth and strong voice cues at word level. Significantly higher vocal sound-pressure levels were found following both cues at sentence and word levels. Both cues elicited significantly higher first-formant vowel frequencies and listeners' greater ease-of-understanding ratings at word level. Increases in the percentage of words transcribed correctly and in sentence ease-of-understanding ratings, however, did not reach statistical significance. Considerable variability between children was observed. CONCLUSIONS & IMPLICATIONS: Speech cues targeting greater articulatory excursion and vocal intensity yield significant acoustic changes in French-speaking children with dysarthria. However, the changes may only aid listeners' ease of understanding at word level. The significant findings and great inter-speaker variability are generally consistent with studies on English-speaking children with dysarthria, although changes appear more constrained in these French-speaking children. What this paper adds What is already known on the subject According to the only study comparing effects of speech-cueing strategies on English-speaking children with dysarthria, intelligibility increases when the children are provided with cues aimed to increase articulatory excursion and vocal intensity. Little is known about speech characteristics in French-speaking children with dysarthria and no published research has explored effects of cueing strategies in this population. What this paper adds to existing knowledge This paper is the first study to examine the effects of speech cues on the acoustics and intelligibility of French-speaking children with CP. It provides evidence that the children can make use of cues to modify their speech, although the changes may only aid listeners' ease of understanding at word level. What are the potential or actual clinical implications of this work? For clinicians, the findings suggest that speech cues emphasizing increasing articulatory excursion and vocal intensity show promise for improving the ease of understanding of words produced by francophone children with dysarthria, although improvements may be modest. The variability in the responses also suggests that this population may benefit from a combination of such cues to produce words that are easier to understand.

RESUMO

Global structural brain connectivity has been reported to be sex-dependent with women having increased interhemispheric connectivity (InterHc) and men having greater intrahemispheric connectivity (IntraHc). However, (a) smaller brains show greater InterHc, (b) larger brains show greater IntraHc, and (c) women have, on average, smaller brains than men. Therefore, sex differences in brain size may modulate sex differences in global brain connectivity. At the behavioural level, sex-dependent differences in connectivity are thought to contribute to men-women differences in spatial and verbal abilities. But this has never been tested at the individual level. The current study assessed whether individual differences in global structural connectome measures (InterHc, IntraHc and the ratio of InterHc relative to IntraHc) predict spatial and verbal ability while accounting for the effect of sex and brain size. The sample included forty men and forty women, who did neither differ in age nor in verbal and spatial latent components defined by a broad battery of tests and tasks. High-resolution T1-weighted and diffusion-weighted images were obtained for computing brain size and reconstructing the structural connectome. Results showed that men had higher IntraHc than women, while women had an increased ratio InterHc/IntraHc. However, these sex differences were modulated by brain size. Increased InterHc relative to IntraHc predicted higher spatial and verbal ability irrespective of sex and brain size. The positive correlations between the ratio InterHc/IntraHc and the spatial and verbal abilities were confirmed in 1000 random samples generated by bootstrapping. Therefore, sex differences in global structural connectome connectivity were modulated by brain size and did not underlie sex differences in verbal and spatial abilities. Rather, the level of dominance of InterHc over IntraHc may be associated with individual differences in verbal and spatial abilities in both men and women.

RESUMO

On average, men show larger brain volumes than women. Regional differences have been also observed, although most of the available studies apply voxel-based morphometry (VBM). Reports applying surface-based morphometry (SBM) have been focused mainly on cortical thickness (CT). Here we apply SBM for obtaining global and regional indices of CT, cortical surface area (CSA), and cortical gray matter volume (CGMV) from samples of men (N=40) and women (N=40) matched for their performance on four cognitive factors varying in their complexity: processing speed, attention control, working memory capacity, and fluid intelligence. These were the main findings: 1) CT and CSA produced very weak correlations in both sexes, 2) men showed larger values in CT, CSA, and CGMV, and 3) cognitive performance was unrelated to brain structural variation within sexes. Therefore, we found substantial group differences in brain structure, but there was no relationship with cognitive performance both between and within-sexes.

RESUMO

Intelligence is composed of a set of cognitive abilities hierarchically organized. General and specific abilities capture distinguishable, but related, facets of the intelligence construct. Here, we analyze gray matter with three morphometric indices (volume, cortical surface area, and cortical thickness) at three levels of the intelligence hierarchy (tests, first-order factors, and a higher-order general factor, g). A group of one hundred and four healthy young adults completed a cognitive battery and underwent high-resolution structural MRI. Latent scores were computed for the intelligence factors and tests were also analyzed. The key finding reveals substantial variability in gray matter correlates at the test level, which is substantially reduced for the first-order and the higher-order factors. This supports a reversed hierarchy in the brain with respect to cognitive abilities at different psychometric levels: the greater the generality, the smaller the number of relevant gray matter clusters accounting for individual differences in intelligent performance.

RESUMO

Neuroimaging studies provide evidence for organized intrinsic activity under task-free conditions. This activity serves functionally relevant brain systems supporting cognition. Here, we analyze changes in resting-state functional connectivity after videogame practice applying a test-retest design. Twenty young females were selected from a group of 100 participants tested on four standardized cognitive ability tests. The practice and control groups were carefully matched on their ability scores. The practice group played during two sessions per week across 4 weeks (16 h total) under strict supervision in the laboratory, showing systematic performance improvements in the game. A group independent component analysis (GICA) applying multisession temporal concatenation on test-retest resting-state fMRI, jointly with a dual-regression approach, was computed. Supporting the main hypothesis, the key finding reveals an increased correlated activity during rest in certain predefined resting state networks (albeit using uncorrected statistics) attributable to practice with the cognitively demanding tasks of the videogame. Observed changes were mainly concentrated on parietofrontal networks involved in heterogeneous cognitive functions.

RESUMO

Aluja, Kuhlman, and Zuckerman (2010) developed an instrument for American and Spanish populations (Zuckerman-Kuhlman-Aluja Personality Questionnaire [ZKA-PQ]) that includes 4 facets for each 5 basic traits of Zuckerman's psychobiological personality model. This new instrument is intended to improve the previous measure based on the same personality model, the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ), by including the narrower traits (facets) defining the factors. This article explores the convergent and discriminant validity of the new instrument relative to the NEO PI-R in a sample from the Spanish general population. A series of exploratory factor analyses comparing both instruments was conducted. Results showed good convergent and discriminant validity between both instruments, although the ZKA-PQ had a slightly better structure than the NEO PI-R. The results support the validity of the ZKA-PQ factor domains and the facets composing them. The new instrument might be useful in both applied and research settings.

RESUMO

The aim of this study was to compare the psychometric properties (normal distribution values, reliabilities and factor structure) of the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) and the Temperament and Character Inventory revised (TCI-R). The total sample consisted of 482 subjects (53.1% men and 46.9% women) from diverse age. Results showed somewhat better psychometric properties, like reliability and facet-factor structure, for the ZKA-PQ than the TCI-R. The expected five-factor facet structure of the ZKA-PQ was clear found. However, the seven-factor structure of TCI-R was not clear and it did not show a clear distinction between Temperament and Character factors. When ZKA-PQ and TCI-R variables are analyzed together, the ZKA-PQ factors are related to the Character as well as the Temperament factors. In some cases they represent the opposite poles of ZKA-PQ factors; for example, Neuroticism versus Self-Directiveness and Aggression versus Cooperativeness. Some are directly and highly related to ZKA-PQ factors; for example, Sensation Seeking and Novelty Seeking, Extraversion and Reward Dependence, Neuroticism and Harm Avoidance, and Activity and Persistence.

RESUMO

Assortative mating is the individuals' tendency to mate with those who are similar to them in some variables, at a higher rate than would be expected from random. This study aims to provide empirical evidence of assortative mating through the Big Five model of personality and two measures of intelligence using Spanish samples. The sample consisted of 244 Spanish couples. It was divided into two groups according to relationship time. The effect of age, educational level and socioeconomic status was controlled. The results showed strong assortative mating for intelligence and moderate for personality. The strongest correlations for Personality were found in Openness, Agreeableness and Conscientiousness.

RESUMO

Sexual attraction was considered a component of sexual orientation from the beginning of the second half of the 20th century to present times. However, some recent researchers have studied sexual attraction as an independent field measuring it by the Sexual Attraction Questionnaire (SAQ). This study analyzes sexual attraction through the SAQ in 400 university students from a Peruvian catholic university. These participants -191 women and 209 men- show a very diverse curricular background. The following hypotheses were tested: a) the structure of the SAQ, pointing out two concepts: attraction to men and attraction to women; b) the high inverse correlation between these two concepts or factors; c) the specific impact of this context in sexual attraction: higher percentage of attracted by none of the sexes and lower percentage of attracted to the opposite sex, in comparison with other contexts; and d) the Lippa prediction (2006, 2007), regarding a higher polarization of sexual attraction for men than for women. Results support the first three hypotheses. Clarifications are laid down with regard to the fourth one. Discussion focuses on theoretical and applied advantages of using the SAQ as opposed to the frequent use of a single item of sexual attraction for each sex.

RESUMO

Children and people with intellectual disability (ID) are considered to be highly vulnerable and in need of special protection against sexual abuse (SA). The objective of this work was to analyze the characteristics of cases of SA in children with typical development and in people with ID in Spain. To do so, 25 cases of each type that had been investigated by specialized groups of the Judicial Police of the Spanish Civil Guard and that had been classified as proven and confirmed by police and forensic-medical evidence were analyzed. The results allowed the establishment of the typical minor victim profile as Spanish female (76%), with an average age of 8.64 years. Typical victim with ID was characterized as being of Spanish, aged 20.28 years on average, without prior sexual experience, and similar percentages of males (40%) and females (60%). In both cases, the aggressor usually acted alone, was known to the victim, had an average age of 42 years, and without a history of sexual offenses. The most common child sexual crime was SA with penetration, practiced repeatedly, using strategies such as the use of force, authority, rewards, or secrecy. Victims with ID suffered sexual abuse with penetration, using force, authority, threats or blackmail. Finally, 36% of minors not disclose the events by only 8% of victims with ID. Spontaneity was found in the 40% first disclosure in both victims, with greater police evidence and greater recognition of guilt on behalf of the aggressors against victims without disabilities. Minors took an average of 26.26 days to report the facts, and victims with ID of 64.94. It is necessary to know more about these types of offenses to design appropriate prevention and detection programs.

RESUMO

Purpose This study examined the effects of Speech Intelligibility Treatment (SIT) on intelligibility and naturalness of narrative speech produced by francophone children with dysarthria due to cerebral palsy. Method Ten francophone children with dysarthria were randomized to one of two treatments, SIT or Hand-Arm Bimanual Intensive Therapy Including Lower Extremities, a physical therapy (PT) treatment. Both treatments were conducted in a camp setting and were comparable in dosage. The children were recorded pre- and posttreatment producing a story narrative. Intelligibility was measured by means of 60 blinded listeners' orthographic transcription accuracy (percentage of words transcribed correctly). The listeners also rated the children's naturalness on a visual analogue scale. Results A significant pre- to posttreatment increase in intelligibility was found for the SIT group, but not for the PT group, with great individual variability observed among the children. No significant changes were found for naturalness ratings or sound pressure level in the SIT group or the PT group posttreatment. Articulation rate increased in both treatment groups, although not differentially across treatments. Conclusions Findings from this first treatment study on intelligibility in francophone children with dysarthria suggest that SIT shows promise for increasing narrative intelligibility in this population. Acoustic contributors to the increased intelligibility remain to be explored further. Supplemental Material https://doi.org/10.23641/asha.14161943.

RESUMO

Resting state functional connectivity research has shown that general cognitive ability (GCA) is associated with brain resilience to targeted and random attacks (TAs and RAs). However, it remains to be seen if the finding generalizes to structural connectivity. Furthermore, individuals showing performance levels at the very high area of the GCA distribution have not yet been analyzed in this regard. Here we study the relation between TAs and RAs to structural brain networks and GCA. Structural and diffusion-weighted MRI brain images were collected from 189 participants: 60 high cognitive ability (HCA) and 129 average cognitive ability (ACA) individuals. All participants completed a standardized fluid reasoning ability test and the results revealed an average HCA-ACA difference equivalent to 33 IQ points. Automated parcellation of cortical and subcortical nodes was combined with tractography to achieve an 82 × 82 connectivity matrix for each subject. Graph metrics were derived from the structural connectivity matrices. A simulation approach was used to evaluate the effects of recursively removing nodes according to their network centrality (TAs) versus eliminating nodes at random (RAs). HCA individuals showed greater network integrity at baseline and prior to network collapse than ACA individuals. These effects were more evident for TAs than RAs. The networks of HCA individuals were less degraded by the removal of nodes corresponding to more complex information processing stages of the PFIT network, and from removing nodes with larger empirically observed centrality values. Analyzed network features suggest quantitative instead of qualitative differences at different levels of the cognitive ability distribution.

RESUMO

Biological (BA) and chronological (CA) age may or may not fit. The available evidence reveals remarkable individual differences in the overlap/mismatch between BA and CA. Increased mismatch can be interpreted as delayed (BA/CA < 1) or accelerated biological aging (BA/CA > 1). Body and brain health are correlated and both predict aging outcomes associated with physical and mental fitness. Moreover, research has shown that older brain age at midlife correlates negatively with cognitive ability measured in early childhood, which suggests early life predisposition to accelerated aging in adulthood. Under this framework, here we test if increased cognitive ability is associated with delayed brain aging, analyzing structural MRI data of 188 individuals, sixty of whom were recruited from MENSA, an association comprising individuals who obtained cognitive ability scores in the top 2 percent of the population. These high ability individuals (HCA) showed an average advantage of 33 IQ points, on a fluid reasoning test they completed for this research, over those other recruited because of their average cognitive ability (ACA). Next, brain age was computed at the individual level for two distinguishable neocortical features (thickness and surface area) according to models trained in an independent large-scale sample of 2377 individuals. Results revealed a stronger pattern of accelerated brain aging in HCA compared to ACA individuals for thickness, while the opposite pattern was suggested for surface area. The findings align well with the greater relevance of individual differences in cortical surface area for enhancing our understanding of cognitive differences at the brain level.

RESUMO

BACKGROUND: Are cognitive and biological variables useful for predicting future behavioral outcomes? METHOD: In two independent groups, we measured a set of cognitive (fluid and crystallized intelligence, working memory, and attention control) and biological (cortical thickness and cortical surface area) variables on two occasions separated by six months, to predict behavioral outcomes of interest (performance on an adaptive version of the n-back task) measured twelve and eighteen months later. We followed three stages: discovery, validation, and generalization. In the discovery stage, cognitive/biological variables and the behavioral outcome of interest were assessed in a group of individuals (in-sample). In the validation stage, the cognitive and biological variables were related with a parallel version of the behavioral outcome assessed several months later. In the generalization stage, the validation findings were tested in an independent group of individuals (out-of-sample). RESULTS: The key finding revealed that cortical surface area variations within the right dorsolateral prefrontal cortex predict the behavioral outcome of interest in both groups, whereas the cognitive variables failed to show reliable predictive validity. CONCLUSIONS: Individual differences in biological variables might predict future behavioral outcomes better than cognitive variables concurrently correlated with these behavioral outcomes.

RESUMO

Here we analyze the simultaneous relationships among five variables. Two refer to childhood (episodes of various forms of maltreatment and externalizing behaviors), whereas three refer to early adulthood (intelligence, personality, and socialization difficulties). The 120 individuals considered for the present report were invited from the 650 schoolchildren participating in the Longitudinal Study of Intelligence and Personality (Minas Gerais, Brazil). The complete sample was recruited in 2002 (T1; mean age = 10.0; standard deviation (SD) = 2.2) and 120 were tested again in 2014-17 (T2; mean age = 23.5; SD = 2.2). Externalizing behaviors were registered at T1, whereas the remaining variables were obtained at T2. These were the main results: (1) externalizing behaviors predict future social effectiveness (as estimated by the general factor of personality derived from the NEO Personality Inventory-Revised (NEO-PI-R) and socialization difficulties computed from the socialization scale (SOC)) and future intelligence performance (as assessed by a set of fluid and crystallized tests); (2) episodes of self-reported childhood maltreatment predict social effectiveness, but not intelligence; (3) maltreatment and externalizing behaviors are unrelated; and (4) social effectiveness (personality) and intelligence are unrelated. Therefore, the findings support the dissociation between adult intelligence and personality with respect to maltreatment episodes and externalizing behaviors occurring in childhood. Implications of these findings for social policies aimed at preventing adult socially ineffective personalities are underscored.

RESUMO

The general (g) factor is the most general and relevant cognitive ability. This factor is considered to be one of the most important predictors of academic achievement and of many other socially relevant behavioral outcomes. In the last decades, many researchers have investigated the possible changes in the relevance of the g factor from childhood to adulthood. The indifferentiation hypothesis states that the variance attributed to the g factor and the main cognitive abilities will not change over the life span. In the present study, the authors tested that hypothesis in childhood, adolescence, and adulthood by using 2 different cognitive batteries (Test of Educational Ability [TEA; S. A. TEA, 1999], Wechsler Adult Intelligence Scales [WAIS; D. Wechsler, 1955]), which they administered in 2 different countries--Spain (TEA) and the United States (WAIS). The ages of the participants (N = 2,384) ranged from 8 to 54 years. Results showed that the number of factors extracted and the relevance were the same for every age group in both batteries, as predicted by the indifferentiation hypothesis. The authors discuss implications of intelligence assessment.

RESUMO

The aim of this work is to analyze the gender differences in the scales of a recently constructed test: the so-called EDTC. This test measures the following traits: sensation seeking, fearlessness, and impulsivity. Gender differences will be studied using Differential Item Functioning (DIF) techniques, in order to determine whether these differences are true differences in the assessed dimensions or if, on the contrary, they are the result of a mere artefact of the measuring instrument used. The methods used to study DIF are standardization, SIBTEST, logistic regression, Lord's chi 2 test, and indices based on the DFIT model. Despite the fact that some items with DIF exist, the gender differences observed seem to be the result of true differences in the measured personality constructs and they don't seem to be artificially produced by a bias in the test items.

RESUMO

Many studies have shown that IQs have been increasing over the last half century. These increases have come to be known as "the Flynn effect". The "Flynn effect" represents a difference on ability-level between groups of the same age but different cohort. The ability-level differentiation hypothesis represents a difference on the relevance of cognitive factors between groups of high and low ability. Hence, it should be possible to imitate the ability-level differentiation effect by comparing groups of the same age but different cohort. The indifferentiation hypothesis represents no differences on the relevance of cognitive abilities in all age groups within the same cohort. The aim of the present study is to test the relationships between these phenomena. For this purpose we analyzed the American standardisation samples of the WISC, WISC-R and WISC-III. Results support the link between the Flynn effect and the differentiation hypothesis. Also, reported evidence replicate previous findings supporting the indifferentiation hypothesis. Implications for the assessment of the intelligence are discussed.

RESUMO

BACKGROUND: In spite of the verifiable achievements obtained in gender equity, one wonders if they still exist in our societies gendered activities (roles) at the household level. This study states an affirmative prediction. Gender role is here organized in four different nuclei: instrumentality inside and outside home for men; expressiveness and instrumentality inside home for women, pertaining to two clearly different domains (household activities for men and household activities for women). METHOD: 98 women and 86 men completed the Gender Roles Questionnaire (GRQ). RESULTS: Obtained results showed that: (a) men and women do not do certain household activities (roles) with the same frequency; (b) the four-dimensional approach fits the data better than the one-dimensional and even better than the two-dimensional approach (household gender roles for men and women separately). CONCLUSION: Discussion focuses on the implications of these results for both research and education.

RESUMO

Research findings suggest that sex offenders show worse performance than the general population in neuropsychological tests. Nevertheless, moderators such as age of the victim, use of antisocial control groups, and characteristics of administered measures have been highlighted. Here, 100 participants completed a battery of cognitive measures tapping fluid reasoning, verbal ability, and three basic executive processes (inhibition, switching, and updating). They were matched by educational level and classified in four groups: controls, non-sex offenders, rapists, and child abusers. The analyses revealed that rapists showed lower fluid reasoning scores than controls and child abusers. Furthermore, rapists and child abusers showed lower executive updating performance than controls and non-sex offenders. Importantly, child abusers did show fluid reasoning scores on a par with controls (controlling for updating differences), but their executive updating performance was equivalent to the one revealed by rapists (controlling for fluid intelligence differences). Implications of these findings for the design of efficient intervention programs are discussed


Los datos de investigación empírica sugieren que los delincuentes sexuales presentan un peor desempeño que la población general en las pruebas neuropsicológicas. Aun así, se ha resaltado la influencia de variables moderadoras como la edad de la víctima, el uso de grupos control que incluyan individuos antisociales y las características de las medidas utilizadas. En este estudio cien participantes completaron una batería de pruebas cognitivas que evalúan razonamiento fluido, capacidad verbal y tres funciones ejecutivas básicas (inhibición, cambio y actualización). Los participantes estaban igualados en su nivel educativo y divididos en cuatro grupos: controles, delincuentes no sexuales, agresores sexuales con víctimas adultas y abusadores de menores. Los análisis revelaron que los agresores sexuales con víctimas adultas presentaban puntuaciones menores que los controles y los abusadores de menores en razonamiento fluido. Más aún, los agresores con víctimas adultas y los abusadores tenían peor desempeño que los controles y los delincuentes no sexuales en actualización ejecutiva. Es destacable que los abusadores de menores mostraran puntuaciones en razonamiento fluido equiparables a las de los controles (controlando estadísticamente las diferencias en actualización), pero su desempeño en actualización ejecutiva fue equivalente al mostrado por los agresores con víctimas adultas (controlando estadísticamente las diferencias en inteligencia fluida). Finalmente se discuten las implicaciones de estos resultados para el diseño de programas de intervención efectivos
