Tracking nonliteral language processing using audiovisual scenarios.

Recognizing sarcasm and jocularity during face-to-face communication requires the integration of verbal, paralinguistic, and nonverbal cues, yet most previous research on nonliteral language processing has been carried out using written or static stimuli. In the current study, we examined the processing of dynamic literal and nonliteral intentions using eye tracking. Participants (N = 37) viewed short, ecologically valid video vignettes and were asked to identify the speakers' intention. Participants had greater difficulty identifying jocular statements as insincere in comparison to sarcastic statements and spent significantly more time looking at faces during nonliteral versus literal social interactions. Finally, participants took longer to shift their attention from one talker to the other talker during interactions that conveyed literal positive intentions compared with jocular and literal negative intentions. These findings currently support the Standard Pragmatic Model and the Parallel-Constraint-Satisfaction Model of nonliteral language processing.

Assessing pragmatic language in autism spectrum disorder: the Yale in vivo Pragmatic Protocol.

PURPOSE: This study compared pragmatic language in youths (9-17 years) with autism spectrum disorder (ASD) and those with typical development (TD) on the Yale in vivo Pragmatic Protocol (YiPP), a semistructured, dynamic conversational assessment. METHOD: Participants (n = 118) were divided into groups based on age and diagnosis. Each completed the YiPP, which included 4 pragmatic domains (discourse management, communicative functions, conversational repair, presupposition). The participant's response to each probe was scored correct or incorrect; incorrect scores elicited cues from the examiner, and level of cue required for a correction was also scored. RESULTS: The YiPP showed high reliability and internal consistency, with moderate concurrent validity, sensitivity, and specificity. The group with ASD performed worse overall on YiPP probes compared to their TD counterparts on both error (d = 0.96) and cue (d = 0.91) scores. Item analyses revealed greater gaps between older students with ASD and their TD peers than between the 2 younger groups. CONCLUSIONS: These data suggest that a probe measure designed to assess pragmatic abilities in children with ASD within a conversational context has some validity for contributing to diagnostic classification and can identify specific areas of pragmatic vulnerabilities as part of a clinical assessment.

Prosodic development in middle childhood and adolescence in high-functioning autism.

The present study aims to investigate the perception and production of several domains of prosodic performance in a cross-sectional sample of preadolescents and adolescents with and without high-functioning autism (HFA). To look at the role of language abilities on prosodic performance, the HFA groups were subdivided based on "high" and "low" language performance on the Clinical Evaluation of Language Fundamentals-Fourth Edition (CELF-4) (Semel, Wiig, & Secord). Social and cognitive abilities were also examined to determine their relationship to prosodic performance. No significant differences were seen in prosody scores in the younger versus older subgroups in typically developing (TD) group with age-appropriate language. There was small but significant improvement in performance with age in the groups with HFA. Comparing performance at each age level across diagnostic groups showed that preteens with HFA and higher language levels perform similarly to their TD peers on all prosodic tasks, whereas those with lower language skills scored significantly worse than both their higher language and TD peers when looking at composite perception and production findings. Teens with HFA showed no deficits on perception tasks; however, those with low language levels had difficulty on several production tasks when compared to the TD group. Regression analyses suggested that, for the preteen group with HFA, language was the strongest predictor of prosodic perception, whereas nonverbal IQ was most highly predictive of prosodic production. For adolescents with HFA, social skills significantly contributed to the prediction of prosodic perception and, along with language abilities, predicted prosodic production. Implications of these findings will be discussed.

Enhancing the application and evaluation of a discrete trial intervention package for eliciting first words in preverbal preschoolers with ASD.

This study evaluates the effectiveness of an intervention package including a discrete trial program (Rapid Motor Imitation Antecedent Training (Tsiouri and Greer, J Behav Educat 12:185-206, 2003) combined with parent education for eliciting first words in children with ASD who had little or no spoken language. Evaluation of the approach includes specific intervention targets and functional spoken language outcomes (Tager-Flusberg et al., J Speech Lang Hear Res 52:643-652, 2009). Results suggest that RMIA, with parent training, catalyzes development of verbal imitation and production for some children. Three of five participants acquired word production within the DTT framework and achieved milestones of early functional spoken language use (Tager-Flusberg et al., J Speech Lang Hear Res 52:643-652, 2009). The implications of these findings for understanding the role of discrete trial approaches to language intervention are discussed.
