Tactile Modality

Twenty-four normal-hearing subjects received CV stimuli of uni- and bisensory inputs through the visual (speechreading), tactile (touch), and visual-tactile (speechreading and touch) modalities. Stimuli were presented via either a videotape monitor or a tactile vibrator or both. The purposes were to investigate the contribution of the tactile modality in uni- and bisensory conditions, and to analyze consonantal substitution errors to find perceptual features utilized by the subjects in their decision-making processes. The subjects' consonantal perceptions were phonetically transcribed and submitted to INDSCAL analysis which yielded mainly a four-dimensional solution. The interpretations of these dimensions were primarily closed bilabial, easy to see/hard to see, voiced/voiceless, and front/back place. Additional features were retrieved, but occurred less consistently.

Processing Effort

Purpose The purpose of the current study was to evaluate the social and cognitive underpinnings of miscommunication during an interactive listening task. Method An eye and computer mouse–tracking visual-world paradigm was used to investigate how a listener's cognitive effort (local and global) and decision-making processes were affected by a speaker's use of ambiguity that led to a miscommunication. Results Experiments 1 and 2 found that an environmental cue that made a miscommunication more or less salient impacted listener language processing effort (eye-tracking). Experiment 2 also indicated that listeners may develop different processing heuristics dependent upon the speaker's use of ambiguity that led to a miscommunication, exerting a significant impact on cognition and decision making. We also found that perspective-taking effort and decision-making complexity metrics (computer mouse tracking) predict language processing effort, indicating that instances of miscommunication produced cognitive consequences of indecision, thinking, and cognitive pull. Conclusion Together, these results indicate that listeners behave both reciprocally and adaptively when miscommunications occur, but the way they respond is largely dependent upon the type of ambiguity and how often it is produced by the speaker.

Communication Interventions

Purpose The purpose of this investigation was to understand the decision-making processes used by parents of children with autism spectrum disorder (ASD) related to communication-based interventions. Method Qualitative interview methodology was used. Data were gathered through interviews. Each parent had a child with ASD who was at least four-years-old; lived with their child with ASD; had a child with ASD without functional speech for communication; and used at least two different communication interventions. Results Parents considered several sources of information for learning about interventions and provided various reasons to initiate and discontinue a communication intervention. Parents also discussed challenges introduced once opinions of the school individualized education program (IEP) team had to be considered. Conclusions Parents of children with ASD primarily use individual decision-making processes to select interventions. This discrepancy speaks to the need for parents and professionals to share a common “language” about interventions and the decision-making process.
