Description
Frequency effects favoring high print-frequency words have been observed in frequency judgment memory tasks. Healthy young adults performed frequency judgment tasks; one group performed a single task while another group did the same task while alternating their attention to a secondary task (mathematical equations). Performance was assessed by correct and error responses, reaction times, and accuracy. Accuracy and reaction times were analyzed in terms of memory load (task condition), number of repetitions, effect of high vs. low print-frequency, and correlations with working memory span. Multinomial tree analyses were also completed to investigate source vs. item memory and revealed a mirror effect in episodic memory experiments (source memory), but a frequency advantage in span tasks (item memory). Interestingly enough, we did not observe an advantage for high working memory span individuals in frequency judgments, even when participants split their attention during the dual task (similar to a complex span task). However, we concluded that both the amount of attentional resources allocated and prior experience with an item affect how it is stored in memory.

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
The purpose of this study was to evaluate the effects of parent training in the Enhanced Milieu Teaching with Phonological Emphasis (EMT+PE) intervention program, using telepractice, on parent strategy use and child speech and language outcomes for children with repaired cleft palate with or without lip (CP/L). Four parent child dyads participated in the study. Child participants ranged in age from 28 to 53 months at the beginning of intervention and all had a diagnosis of nonsyndromic CP/L. Participants received two-to-three parent training sessions and twice weekly telepractice intervention sessions. Parents increased their use of EMT+PE strategies throughout intervention with the Modeling and Expansion and Prompting and Recasting strategies resulting in significant intervention effects. Moreover, parents maintained increased strategy use following the conclusion of direct intervention. A positive improvement in child speech and language outcomes was seen across intervention. This study showed that telepractice is an effective service delivery model for parent training and subsequent intervention session in EMT+PE strategy use to support the speech and language development for children with CP/L.

Description
The purpose of this study is to evaluate the effects of parent training in the Enhanced Milieu Teaching with Phonological Emphasis (EMT+PE) intervention program, using a secure internet-based conferencing software (telepractice), on parent strategy use and child speech and language outcomes for children with repaired cleft lip and/or palate (CL/P). Three participant dyads composed of a parent and child participated in this study. Children ranged in age from 21 to 27 months at the beginning of this study and all had a diagnosis of nonsyndromic CL/P. Participating dyads received three in- person training sessions and three weekly telepractice intervention sessions. Assessment and intervention sessions were administered by a trained Speech Language Pathologist (SLP) and a graduate SLP student clinician. Parents demonstrated a positive intervention effect by significantly increasing their use of EMT+PE intervention strategies during training. Based on preliminary results, parents were able to maintain their increased use of strategies following the conclusion of intervention as well. Telepractice proved to be a valid service delivery model for conducting early intervention sessions and for supporting the early speech and language development for children with CL/P.
