Provision of Genetic Services for Hearing Loss: Results from a National Survey and Comparison to Insights Obtained from Previous Focus Group Discussions

Hearing loss is a common sensory deficit and more than 50% of affected individuals have a genetic etiology. The discovery of 40 genes and more than 100 loci involved in hearing loss has made genetic testing for some of these genes widely available. Genetic services for deafness are also being sought more often due to the early identification of hearing loss through newborn screening services. The motivations for pursuing genetic testing, and how genetic services are provided to the client may differ among individuals. Additionally, information obtained through genetic testing can be perceived and used in different ways by parents of deaf children and deaf adults. This study aimed to follow up on focus group studies published earlier with a quantitative survey instrument and assess the preference of consumers for provision of genetic services. We conducted a national survey of hearing and deaf parents of children with hearing loss and of deaf adults. Data was compared and analyzed by hearing status of the participant, their community affiliation and the genetic testing status using nominal logistic regression. Consistent with our focus group results, the survey participants thought that a genetic counselor/geneticist would be the most appropriate professional to provide genetics services. Statistically significant differences were noted in the preferred choice of provider based on the genetic testing status. Parents preferred that genetic evaluation, including testing, occur either immediately at or a few months after the audiologic diagnosis of hearing loss. This data should help providers in clinical genetics keep patient preferences at the helm and provide culturally competent services.     

The role of cognition and coping in health behavior outcomes of asthmatic patients

This study investigates the meaning of cognitions and coping in well-being, hospital admissions, medication consumption, and absence from work due to asthma in asthmatic patients. Patients completed five questionnaires: the Respiratory Illness Opinion Survey (Kinsman, Jones, Matus, & Schum, 1976), measuring external control, psychological stigma, and optimism; the Asthma Coping Questionnaire (Maes, Schl?sser, & Vromans, 1986), measuring coping mechanisms; the Dutch version of the STAI (van der Ploeg, Defares, & Spielberger, 1979), measuring state and trait anxiety; the Questionnaire for Inner Well-Being (Hermans & Tak-van de Ven, 1973), measuring well-being; and the General Questionnaire for Asthmatic Patients (Maes et al., 1986) measuring medical outcome. Stepwise multiple regression showed that cognitions and coping determined a considerable part of the variance in the dependent variables: well-being, hospital admissions, and absence from work due to asthma.     

Procedural learning across the lifespan: A systematic review with implications for atypical development

This systematic review aimed to investigate procedural learning across the lifespan in typical and atypical development. Procedural learning is essential for the development of everyday skills, including language and communication skills. Although procedural learning efficiency has been extensively studied, there is no consensus yet on potential procedural learning changes during development and ageing. Currently, three conflicting models regarding this trajectory exist: (1) a model of age invariance; (2a) a model with a peak in young adulthood; and (2b) a model with a plateau in childhood followed by a decline. The aims of this study were (1) to investigate this debate on procedural learning across the lifespan by systematically reviewing evidence for each model from studies using the serial reaction time task; and (2) to review procedural learning in autism spectrum disorder (ASD) and specific language impairment (SLI), two developmental disorders characterized by deficits in communication skills, in the light of these models. Our findings on typical development strongly support a model of age-related changes (Model 2a or 2b) and show that mixed findings regarding the developmental trajectory during childhood can be explained by methodological differences across studies. Applying these conclusions to systematic reviews of studies of ASD and SLI makes it clear that there is a strong need for the inclusion of multiple age groups in these clinical studies to model procedural learning in atypical development. Clinical implications of the findings are discussed. Future research should focus on the role of declarative learning in both typical and atypical development.     

Training and transfer effects of response inhibition training in children and adults

Response inhibition is crucial for mental and physical health but studies assessing the trainability of this type of inhibition are rare. Thirty‐nine children aged 10‐12 years and 46 adults aged 18‐24 years were assigned to an adaptive go/no‐go inhibition training condition or an active control condition. Transfer of training effects to performance on tasks assessing response inhibition, interference control, working memory updating, task‐switching, and non‐verbal fluid intelligence were assessed during 3‐ and 6‐month follow‐up sessions and/or an immediate post‐training session. Significant training improvements and positive transfer effects to a similar response inhibition task with other stimuli were observed for both children and adults. Reliable albeit short‐lived transfer effects were only found for the children, specifically to working memory updating and task switching. These results suggest some potential for response‐inhibition training programs to enhance aspects of cognitive functioning in children but not adults.     

Understanding biological and social influences on religious affiliation, attitudes, and behaviors: a behavior genetic perspective

Although the transmission of religiousness has been assumed to be purely cultural, behavior genetic studies have demonstrated that genetic factors play a role in the individual differences in some religious traits. This article reviews the extant behavior genetic literature and presents new analyses from the "Virginia 30,000" on the causes of variation in religious affiliation, attitudes, and practices, and relates these to personality as construed by Eysenck. Results indicate that religious affiliation is primarily a culturally transmitted phenomenon, whereas religious attitudes and practices are moderately influenced by genetic factors. Further, Eysenck's personality traits do not mediate genetic influences on religiousness, but significant negative genetic correlations are found between church attendance and liberal sexual attitudes. Implications and possibilities for future studies are discussed.     

Sound improves diminished visual temporal sensitivity in schizophrenia

Visual temporal processing and multisensory integration (MSI) of sound and vision were examined in individuals with schizophrenia using a visual temporal order judgment (TOJ) task. Compared to a non-psychiatric control group, persons with schizophrenia were less sensitive judging the temporal order of two successively presented visual stimuli. However, their sensitivity to visual temporal order improved as in the control group when two accessory sounds were added (temporal ventriloquism). These findings indicate that individuals with schizophrenia have diminished sensitivity to visual temporal order, but no deficits in the integration of low-level auditory and visual information.     

The Development and Experience of Combat‐Related PTSD: A Demand for Neurofeedback as an Effective Form of Treatment

Veterans experience a considerable course of posttraumatic stress disorder (PTSD), and because of several psychosocial issues, traditional interventions and traditional intervention settings are ineffective for this population. A new cutting‐edge approach, known as neurofeedback, trains clients to control and manipulate their central nervous system and ameliorate physiological symptoms of stress disorders. The authors delineate how neurofeedback can be an effective and innovative intervention for PTSD experienced by the military population.     

Improving Route Directions: The Role of Intersection Type and Visual Clutter for Spatial Reference

In this study, we ask whether references to paths and landmarks in route directions (RDs) are influenced by environmental complexity, zooming in on two aspects of the visual surroundings, namely intersection structure and visual clutter. Speakers are asked to produce (Experiment 1), understand (Experiment 2) and evaluate (Experiment 3) turn‐by‐turn RDs in a naturalistic setting (Google Street View panoramic pictures). We find that increased levels of visual clutter and intersections with complex structures trigger more references to landmarks and paths when participants produce RDs, longer decision times to determine what the next correct step in a route is and increased preference for landmarks. Finally, we discuss possible implications for automatic RD generation.Copyright © 2015 John Wiley & Sons, Ltd.     

OpenMx 2.0: Extended Structural Equation and Statistical Modeling

The new software package OpenMx 2.0 for structural equation and other statistical modeling is introduced and its features are described. OpenMx is evolving in a modular direction and now allows a mix-and-match computational approach that separates model expectations from fit functions and optimizers. Major backend architectural improvements include a move to swappable open-source optimizers such as the newly written CSOLNP. Entire new methodologies such as item factor analysis and state space modeling have been implemented. New model expectation functions including support for the expression of models in LISREL syntax and a simplified multigroup expectation function are available. Ease-of-use improvements include helper functions to standardize model parameters and compute their Jacobian-based standard errors, access to model components through standard R $ mechanisms, and improved tab completion from within the R Graphical User Interface.     

Loneliness and Attitudes Toward Being Alone in Belgian and Chinese Adolescents: Examining Measurement Invariance

Loneliness is an adverse phenomenon that tends to peak during adolescence. As loneliness is a subjective state, it is different from the objective state of being alone. People’s attitudes toward being alone can be more or less negative or positive. Cultures differ in the form and meaning of social behavior, interpersonal relationships, and time spent alone. However, for cross-cultural comparisons to be meaningful, measurement invariance of the measure should be established. The present study examined measurement invariance of the Loneliness and Aloneness Scale for Children and Adolescents (LACA) in a sample of 218 Belgian and 190 Chinese early adolescents, aged 11–15 years. Using nested multigroup confirmatory factor analyses, measurement invariance of the LACA across Belgium and China was established. More specifically, evidence was found for configural, metric, and partial scalar invariance. Because partial scalar invariance was established, the two cultural groups could be compared. No significant differences were found for peer-related loneliness. Regarding the attitudes toward aloneness, Belgian adolescents were more negative and less positive toward being alone than Chinese adolescents. The present study is encouraging for researchers who want to use the LACA for cross-cultural comparisons, in that we found evidence for measurement invariance across two disparate cultural groups speaking completely different languages.
