A Cross-cultural Mixed Methods Investigation of Language Socialization Practices.

This embedded mixed methods study explores how cultural differences in language socialization practices influence parent-child verbal interactions. The Language ENvironment Analysis (LENA) System audio recorded families of children who are and are not deaf and hard of hearing in Canada and Vietnam. Software automatically calculated an average conversational turn count. Canadian families participated in more turns than Vietnamese families regardless of hearing status. Interviews with the children's caregivers provided context for these results. Within Vietnamese families, the language socialization practice "Intelligence" results in reduced opportunities for turn-taking, while the Canadian focus on creating personal "Identity" encouraged them. "Intelligence" encompasses Vietnamese participants' desire to ensure their children are learning and "Identity" expresses the Canadian participants' appeal to encourage individuality in their children. The findings suggest directions for the adaptation of intervention. It is the first known study to incorporate LENA results into a mixed methods design.

Stress-Induced Acoustic Variation in L2 and L1 Spanish Vowels.

AIM: We assessed the effect of lexical stress on the duration and quality of Spanish word-final vowels /a, e, o/ produced by American English late intermediate learners of L2 Spanish, as compared to those of native L1 Argentine Spanish speakers. METHODS: Participants read 54 real words ending in /a, e, o/, with either final or penultimate lexical stress, embedded in a text and a word list. We measured vowel duration and both F1 and F2 frequencies at 3 temporal points. RESULTS: stressed vowels were longer than unstressed vowels, in Spanish L1 and L2. L1 and L2 Spanish stressed /a/ and /e/ had higher F1 values than their unstressed counterparts. Only the L2 speakers showed evidence of rising offglides for /e/ and /o/. The L2 and L1 Spanish vowel space was compressed in the absence of stress. CONCLUSION: Lexical stress affected the vowel quality of L1 and L2 Spanish vowels. We provide an up-to-date account of the formant trajectories of Argentine River Plate Spanish word-final /a, e, o/ and offer experimental support to the claim that stress affects the quality of Spanish vowels in word-final contexts.

Using the Language ENvironment Analysis (LENA) System to Investigate Cultural Differences in Conversational Turn Count.

Purpose: This study investigates how the variables of culture and hearing status might influence the amount of parent-child talk families engage in throughout an average day. Method: Seventeen Vietnamese and 8 Canadian families of children with hearing loss and 17 Vietnamese and 13 Canadian families with typically hearing children between the ages of 18 and 48 months old participated in this cross-comparison design study. Each child wore a Language ENvironment Analysis system digital language processor for 3 days. An automated vocal analysis then calculated an average conversational turn count (CTC) for each participant as the variable of investigation. The CTCs for the 4 groups were compared using a Kruskal-Wallis test and a set of planned pairwise comparisons. Results: The Canadian families participated in significantly more conversational turns than the Vietnamese families. No significant difference was found between the Vietnamese or the Canadian cohorts as a function of hearing status. Conclusions: Culture, but not hearing status, influences CTCs as derived by the Language ENvironment Analysis system. Clinicians should consider how cultural communication practices might influence their suggestions for language stimulation.

Similes on the Internet have explanations.

We searched the Internet for expressions linking topics, such as crime, and vehicles, such as disease, as similes (crime is like a disease) and as metaphors (crime is a disease). We counted the number of times the expressions were accompanied by explanations (crime is like a disease because it spreads by direct personal influence). Similes were more likely than metaphors to be accompanied by explanations. Similes may be preferred if a writer wants to express an out-of-the-ordinary relation between the topic and the vehicle.

Phonological encoding in the silent speech of persons who stutter.

UNLABELLED: The purpose of the present study was to investigate the role of phonological encoding in the silent speech of persons who stutter (PWS) and persons who do not stutter (PNS). Participants were 10 PWS (M=30.4 years, S.D.=7.8), matched in age, gender, and handedness with 11 PNS (M=30.1 years, S.D.=7.8). Each participant performed five tasks: a familiarization task, an overt picture naming task, a task of self-monitoring target phonemes during concurrent silent picture naming, a task of monitoring target pure tones in aurally presented tonal sequences, and a simple motor task requiring finger button clicks in response to an auditory tone. Results indicated that PWS were significantly slower in phoneme monitoring compared to PNS. No significant between-group differences were present for response speed during the auditory monitoring, picture naming or simple motor tasks, nor did the two groups differ for percent errors in any of the experimental tasks. The findings were interpreted to suggest a specific deficiency at the level of phonological monitoring, rather than a general monitoring, reaction time or auditory monitoring deficit in PWS. EDUCATIONAL OBJECTIVES: As a result of this activity, the participant should: (1) identify and assess the literature on phonological encoding skills in PWS, (2) enumerate and evaluate some major psycholinguistic theories of stuttering, and (3) describe the mechanism by which defective phonological encoding can disrupt fluent speech production.

Increased midsagittal tongue velocity as indication of articulatory compensation in patients with lateral partial glossectomies.

BACKGROUND: The purpose of this study was to describe the impact of partial lateral glossectomy on midsagittal tongue movement during speech. METHODS: Using B-mode ultrasound, the midsagittal tongue movement of 10 patients with lateral partial glossectomy during a standardized reading passage was analyzed before and after surgery. Six normal adults served as control speakers. The main outcome measure was the tongue velocity during speech. The technique of defect reconstruction (local vs flap) was included as a covariate in the analysis. RESULTS: Following the surgery, all patients significantly increased the velocity of the midsagittal tongue movements during the reading passage. CONCLUSION: The results demonstrated that the patients with partial glossectomy compensated for the lateral tongue resections by increasing the velocity of the residual tongue during speech. The study provides first insights into the biomechanical aspects of spontaneous articulatory compensation following lateral tongue resections.
