Description
In this pilot study, the purpose was to determine if certain language interventions could help bilingual children reduce maze use and improve their story retell abilities. We used language intervention, Story Champs, and its Spanish version, Puente de Cuentos to help bilingual children improve their story retell abilities. We conducted the intervention over the course of three days in both Spanish and English. The children participated in three stories in each language each day. They also received a narrative measure before and after the intervention to measure gains in story ability and to measure maze use. Results of the study indicated that there were no statistically-significant differences in the children's story retell abilities or maze use before and after the intervention. Nevertheless, we are encouraged by our results for future further study because of some improvements the children made.

Description
This pilot study evaluated whether Story Champs and Puente de Cuentos helped bilingual preschoolers increase their usage of emotional terms and ability to tell stories. Participants in this study included 10 Spanish-English bilingual preschoolers. Intervention was conducted in 9 sessions over 3 days using the Test of Narrative Retell to measure results. Results did not find significant gains in either emotional term usage or ability to tell stories, but the results were promising as a pilot study.

Description
The bilingual experience is an often-studied multivariate phenomenon with a heterogeneous population that is often described using subtypes of bilingualism. “Bilingualism” as well as its subtypes lack consistent definitions and often share overlapping features, requiring researchers to measure a number of aspects of the bilingual experience. Different variables have been operationalized to quantify the language proficiencies, use, and histories of bilinguals, but the combination of these variables and their contributions to these subtypes often vary between studies on bilingualism. Research supports that these variables have an influence not only on bilingual classification, but also on non-linguistic outcomes including perceptions of self-worth and bicultural identification. To date, there is a lack of research comparing the quantification of these bilingual subtypes and these non-linguistic outcomes, despite research supporting the need to address both. Person-centered approaches such as latent profile analysis (LPA) and fuzzy set qualitative comparative analysis (fsQCA) have been applied to describe other multivariate constructs with heterogeneous populations, but these applications have yet to be used with bilingualism. The present study integrates models of bilingualism with these analytic methods in order to quantitatively identify latent profiles of bilinguals, describe the sets of conditions that define these subtypes, and to characterize the subjective experiences that differentiate these subtypes. The first study uses an existing data set of participants who completed the Language and Social Background Questionnaire (LSBQ) and performs LPA and fsQCA, identifying latent profiles and the sets of conditions that these subtypes. The following studies use a second set of bilinguals who also completed the LSBQ as well as a supplementary questionnaire, characterizing their identification with biculturalism and their feelings of self-worth. The analyses are repeated with these data to describe the profiles within these data and the subjective experiences in common. Finally, all analyses are repeated with the combined datasets to develop a final model of bilingual subtypes, describing the differences in language use and history within each subtype. Results demonstrate that latent models can be used to consistently characterize bilingual subtypes, while also providing additional information about the relationship between individual bilingual history and attitudes towards cultural identification.

Description
Individuals with autism spectrum disorder (ASD) are known to show impairments in various domains of executive function (EF) such as behavioral flexibility or inhibitory control. Research suggests that EF impairment in adults with ASD may relate to ASD core symptoms, restrictive behaviors and social communication deficits. Mindfulness-based stress reduction (MBSR) has shown promise for improving EF abilities in neurotypical adults, but research has not explored its efficacy or neural mechanisms in adults with ASD. This pilot study examines the effects of an 8-week MBSR intervention on self-report measures of EF and resting-state functional connectivity in a sample of adults with ASD. Fifty-four participants were assigned either to an MBSR group (n = 29) or a social support group (n = 25). Executive function was measured using the BRIEF-2 before and after the intervention for the twenty-seven participants in the second cohort. MBSR-specific improvements in EF were found for BRIEF measures of initiation, inhibition, and working-memory. Resting-state fMRI data was analyzed using independent component analysis (ICA), and group by time resting-state functional connectivity differences were observed between the cerebellar network and frontal regions including the right frontal pole (rFP), medial frontal cortex (MFC) and left and right superior frontal gyri (SFG). The MBSR group showed increases in functional connectivity between the cerebellum and EF regions which correlated with improvements in BRIEF-2 measures. These findings suggest that MBSR may improve EF domains in adults with ASD, and that increases in functional connectivity between the cerebellum and frontal regions while at rest may be a mechanism for such improvements.

Description
Early identification of dyslexia is essential to providing children with the necessary services and support to succeed academically. Current dyslexia screening measures are not widely available for English-speaking monolingual children and those available for bilingual children are not widely used. To contribute to the effort to provide widely available screening for six-year-old English speaking and bilingual children, the ASU Bilingual Language and Literacy Lab, the Child Language and Literacy Lab, Learning to Soar Tutoring, Healing Hearts Pediatrics, and the Phoenix Children’s hospital have collaborated to develop the Dyslexia Screening Questionnaire (DysQ) that is offered in both English and Spanish. The goal of this study (Phase I) was to test the readability and comprehensibility of the DySQ to help ensure that it is accessible to a wide population of English and Spanish-speaking parents. In the second phase of the study, we aim to validate the DySQ by comparing the DySQ results with gold-standard testing for diagnosing dyslexia. The ultimate goal is to implement the DySQ into pediatric settings so that English and Spanish-speaking children may be screened for dyslexia at their 6-year-old well-child check-up.
