A Novel Eye Tracking Paradigm For Indexing Social Avoidance-Related Behavior In Fragile X Syndrome, Jessica Klusek, Carly Moser, Joseph Schmidt, Leonard Abbeduto, Jane E. Roberts

Faculty Publications

Fragile X syndrome (FXS) is characterized by hallmark features of gaze avoidance, reduced social approach, and social anxiety. The development of therapeutics to manage these symptoms has been hindered, in part, by the lack of sensitive outcome measures. This study investigated the utility of a novel eye tracking paradigm for indexing social avoidance-related phenotypes. Adolescent/young adult-aged males with FXS (n=24) and typical development (n=23) participated in the study. Participants viewed faces displaying direct or averted gaze and the first fixation duration on the eyes was recorded as an index of initial stimulus registration. Fixation durations did …

Reliability And Stability Of The Metrical Stress Effect On Segmental Production Accuracy In Persons With Apraxia Of Speech, Dallin J. Bailey, Lisa Bunker, Shannon Mauszycki, Julie L. Wambaugh

Faculty Publications

Background Acquired apraxia of speech (AOS) involves speech-production deficits on both the segmental and suprasegmental levels. Recent research has identified a non-linear interaction between the metrical structure of bisyllabic words and word-production accuracy in German speakers with AOS, with trochaic words (strong–weak stress) being resistant to errors compared with iambic words (weak–strong).

Aims To replicate previous findings in English speakers with AOS, to measure the test–retest reliability of the effect, and to examine the potential impact of different methods of word scoring.

Methods & Procedures Speech samples were collected from 27 speakers with AOS and aphasia. Participants were at least …

Speech-Language Pathologists' Collaboration With Interpreters: Results Of A Current Survey In California, Terry Saenz, Henriette W. Langdon

Faculty Publications

One of the challenges of bilingual speech and language assessment, intervention, and conferencing is the effective collaboration with interpreters in such interpreted interactions when the professional does not share the same spoken language with the client. A survey of California speech-language pathologists who were members of the California Speech-Language-Hearing Association (CSHA) was performed to obtain information on their training to collaborate with, experiences with, and opinions of interpreters. In addition, these professionals were surveyed about the training of the interpreters and suggestions for improvement in interpreted interactions. Findings from 229 participants indicated that: (a) Most of the speech-language pathologists had …

Somatosensory Cross-Modal Reorganization In Children With Cochlear Implants, Garrett Cardon, Anu Sharma

Faculty Publications

Deprived of sensory input, as in deafness, the brain tends to reorganize. Cross-modal reorganization occurs when cortices associated with deficient sensory modalities are recruited by other, intact senses for processing of the latter’s sensory input. Studies have shown that this type of reorganization may affect outcomes when sensory stimulation is later introduced via intervention devices. One such device is the cochlear implant (CI). Hundreds of thousands of CIs have been fitted on people with hearing impairment worldwide, many of them children. Factors such as age of implantation have proven useful in predicting speech perception outcome with these devices in children. …

Chapter Three - Neural Correlates Of Sensory Abnormalities Across Developmental Disabilities, Garrett Cardon

Faculty Publications

Abnormalities in sensory processing are a common feature of many developmental disabilities (DDs). Sensory dysfunction can contribute to deficits in brain maturation, as well as many vital functions. Unfortunately, while some patients with DD benefit from the currently available treatments for sensory dysfunction, many do not. Deficiencies in clinical practice surrounding sensory dysfunction may be related to lack of understanding of the neural mechanisms that underlie sensory abnormalities. Evidence of overlap in sensory symptoms between diagnoses suggests that there may be common neural mechanisms that mediate many aspects of sensory dysfunction. Thus, the current manuscript aims to review the extant …

Proactive Social Validation Of Methods And Procedures Used For Training Speech Production In Aphasia, Tyson G. Harmon, Lucy Hardy, Katarina L. Haley

Faculty Publications

Background: Social validation evaluates the importance and acceptability of treatment goals, procedures, and outcomes. Previous studies for treatments that train speech production in aphasia have applied social validation during the post-treatment period or to treatment protocols that are already fully developed.

Aims: The purposes of this study were to (1) examine the social validity of goals and procedures experienced in speech production treatment for people with aphasia and (2) evaluate the feasibility of procedural choice-making during such tasks.

Method: Seven people with aphasia and eight speech-language pathologists were interviewed about previous treatment that targeted speech production. Participants were also observed …

Polysyllabic Shortening In Speakers Exposed To Two Languages, Todd A. Gibson, Connie Summers

Faculty Publications

Polysyllabic shortening is used to maintain stress-timed rhythm in English, but used negligibly in Spanish. It is unknown how polysyllabic shortening is influenced when individuals are exposed to one language that employs it and one that does not. We calculated polysyllabic shortening for 35 functionally monolingual English-speaking adults and 19 relatively balanced Spanish–English bilingual peers who repeated English and Spanish nonwords. Results showed that speech motor patterns learned early in life might be sufficient to block cross-linguistic transfer of polysyllabic shortening despite limited language proficiency, and bilingual speakers appear to signal membership in the majority language by increasing polysyllabic shortening.

Supporting Individuals With Autism Spectrum Disorder In Understanding And Coping With Complex Social Emotional Issues, Kaitlyn P. Ahlers, Terisa P. Gabrielsen, Danielle Lewis, Anna M. Brady, April Litchford

Faculty Publications

Core deficits in autism spectrum disorder (ASD) center around social communication and behavior. For those with ASD, these deficits complicate the task of learning how to cope with and manage complex social emotional issues. Although individuals with ASD may receive sufficient academic and basic behavioral support in school settings, supports for dealing with complex social emotional issues are more difficult to access, even though these issues significantly impact student learning. When addressing these challenging social- and emotional-based issues, school and professional personnel need more specific instructional skill sets and resources to effectively and compassionately support students with ASD. In this …

The Role Of Efferent Reduction Of Cochlear Compression In The Detection Of Tones In Noise, Shaum Bhagat, Anusha Yellamsetty

Faculty Publications

Stimulation of medial olivocochlear (MOC) efferent neurons reduces basilar membrane (BM) sensitivity and increases the slope of BM input-output (I/O) functions in animal models. Decreased compression of I/O functions associated with activation of MOC efferent neurons may assist in extending the neural response to the tone above that of noise, leading to an improvement in masked thresholds. To evaluate this hypothesis, the distortion-product otoacoustic emission (DPOAE) I/O function, a proxy measure of BM compression, was examined in conditions with presentation of contralateral noise. DPOAE I/O functions were measured at f2 frequencies of 1000 and 2000 Hz in 16 normal-hearing adults. …
