Effective reading interventions for students with specific learning disabilities (SLD) are needed. A multiprobe multiple baseline across participants design was used to evaluate the effects of a video self-modeling intervention (VSM) on reading fluency skills. The VSM interventions effects on self-efficacy were also measured. Four male middle school students with SLD watched a pre-recorded video of themselves reading a passage fluently and were then asked to read another passage. Words correct per minute (WCPM) and accuracy data were taken. Results showed that students read significantly more words correct when they watched themselves read the same passage they were about to read. This study shows that having students watch videos of themselves read, especially if they watch the same passage they will read afterwards, is easy to implement, cost-effective, and worth further investigation.

This qualitative study analyzed interactions between clinicians and a male child, aged 5 years 9 months old, with significant phonological as well as language deficits within a meaning-based phonological intervention implemented over a nine-month period. Play-based intervention strategies were presented in activities that varied in communicative complexity. The clinician, along with graduate-student assistants, frequently modeled and elicited target word productions as they interacted with the child in routines and scripted play contexts. Transcriptions of interactions were analyzed using a conversational analysis that explored engagement and participation, turn taking, and linguistic complexity of utterances produced in adjacent turns. The analyses illustrated ways in which the clinicians structuring of the activities influenced the child's participation. The turn taking exchanges were topically related when dealing with shared, immediate context. The reciprocal nature of the turn taking exchanges, and the child's grammatical productions were analyzed. The study suggests that contextualized intervention can make speech sound production relevant for children with phonological production as well as language deficits.

The current study examined the effects of bite blocks on articulatory kinematics when producing diphthongs /ɑɪ/ and /ɑʊ/ within a phrase. Participants consisted of 20 young adults (10 males, 10 females) with no speech, language or hearing disorders. Participants produced the diphthongs in the carrier phrase Im an owl that hoots. A Northern Digital Instruments Wave electromagnetic articulograph measured the articulatory movements while the speaker produced the stimuli in two conditions (pre bite block insertion and post bite block insertion). Bilateral bite blocks were made using Express dental putty, which is a silicone impression material, in order to create a 10 mm inter-incisal gap. Marker distance, maximum speed, and jaw contribution to tongue movement for three sensors (tongue back, tongue mid, tongue front) were calculated for the diphthongs segmented from the carrier phrase. F1 and F2 transitions and rate were also calculated for each diphthong. Results revealed kinematic differences during diphthong production after the bite block was inserted. Tongue movements independent from the jaw increased after the bite block was inserted, especially during production of the diphthong /ɑʊ/. Bite block by gender interactions during production of the diphthong /ɑɪ/ revealed larger and faster initial movements for males. The results did not reveal any significant acoustic changes other than a longer transition duration. Kinematic adjustments were sufficient to maintain overall similar acoustic output before and after bite block insertion.

The Children's Communication Checklist-Second Edition (CCC-2) is a behavior rating scale developed to address the difficulties of assessing social communication in children. It was designed to be completed by a parent rater. However, since it would be helpful to know the extent to which ratings are context-dependent, this study looked at the agreement between parent and teacher ratings on the CCC-2 as well as the percent agreement on the severity of disorder. Twelve parent-teacher pairs completed the CCC-2 for children who had a documented developmental language disorder with specific impairment in social communication. Cohen's kappas, Cohen's weighted kappas, and percent agreement of severity of disorder were calculated. Kappa results ranged from less than chance agreement to fair agreement. When differentiating between scores that represent disorder and no disorder, parent and teacher percent agreement for the CCC-2 10 subscales range from 42% to 75%. Further delineation between no disorder, disorder, or severe disorder yielded percent agreement ranging from 17% to 50%. Overall percent agreement on the general communication composite was 92%. Results indicate that while parents and teachers have poor to fair agreement on the exact nature of a child's social communication strengths and weaknesses, they largely agree when a social communication problem exists. Lack of agreement likely resulted from the parent and teacher seeing the child in different contexts which required a somewhat different set of social communication abilities, or a difference in rater perception of what is within the developmental norms. These findings suggest that the best indication of a child's social communication profile may lie in a holistic assessment of performance in all the important contexts in a child's life, including school and home.

Hearing loss, as a result of old age, has been linked to a decline in speech perception despite the use of additional listening devices. Even though the relationship between hearing loss and decreased speech perception has been well established, research in this area has often focused on the behavioral aspects of language and not on the functionality of the brain itself. In the present study, the mismatch negativity, an event related potential, was examined in order to determine the differences in speech perception between young adult participants, geriatric normal hearing participants, and geriatric hearing-impaired participants. It was hypothesized that a significantly weaker mismatch negativity would occur in the geriatric hearing-impaired participants when compared to the young adult participants and the geriatric normal hearing participants. A passive same/different discrimination task was administered to 10 young adult controls (5 male, 5 female) and eight older adult participants with and without hearing loss (4 male, 4 female). Data from behavioral responses and event related potentials were recorded from 64 electrodes placed across the scalp. Results demonstrated that the mismatch negativity occurred at various amplitudes across all participants tested; however, an increased latency in the presence of the mismatch negativity was noted for the geriatric normal hearing and the geriatric hearing-impaired participants. Dipoles reconstructed from temporal event related potential data were located in the cortical areas known to be instrumental in auditory and language processing for the young adult participants; however, within the geriatric normal hearing and the geriatric hearing-impaired participants, dipoles were seen in multiple locations not directly associated with language and auditory processing. Although not conclusive, it appears that within the geriatric normal hearing and the geriatric hearing-impaired participants there is slower processing of the speech information, as well as some cognitive confusion which leads to fewer available resources for interpretation.

The current study examined the lingual kinematic and acoustic effects of bite blocks on vowels in a sentence context. Twenty adult native English speakers (10 male, 10 female) with no speech, language, or hearing deficits participated in the study. The corner vowels found in the sentence, The blue spot is on the black key again (i.e., /u/, /ɑ/, /æ/, /i/), were measured kinematically and acoustically immediately before and after bite block insertion. The participants' speech was audio-recorded and their lingual articulatory movements were measured with a Northern Digital Instruments Wave electromagnetic articulograph. The sensor coils were attached to three different parts on the tongue (back, middle, and front). Acoustic analysis of the vowel formants revealed that the vowel articulation index and vowel space area decreased significantly following bite block insertion. Kinematic analysis of the sensors on the tongue revealed that the kinematic vowel articulation index decreased significantly for the back and middle of the tongue but not for the front. Thus, adjustments to the position of the front of the tongue were sufficient to compensate for the bite block perturbation, while the same measures for the back and middle of the tongue were significantly affected. This was likely due to the relative independence in the movement of the front of the tongue, given its distance from the posterior point of attachment between the tongue and mandible. These findings suggest that the effects of articulatory perturbation can be more fully understood when kinematic and acoustic measures are considered together.

This descriptive study provides insight on the prevalence of Emotional and Behavioral Disorders (EBD) screening and school psychologists' roles in that screening process in Utah schools. EBD screening plays an important role in implementing Multi-Tiered System of Supports (MTSS). An electronic questionnaire was sent to 260 practicing Utah school psychologists. A total of 89 of those school psychologists completed the survey resulting in a 34% participation rate. Twelve percent (n=11) of participants reported that EBD screening was happening in their schools. Participants reported that the lack of resources to address student needs, the lack of administrative support, and the school having too many other concerns were barriers to EBD screening implementation. Survey results also reported that successful EBD screening consisted of a combined effort consisting of teams, administration, and school districts. Additionally, school psychologists reported that their role in EBD screening should mainly be focused on data interpretation and intervention implementation. The goal of this thesis project was to increase awareness of how universal EBD screening was occurring in Utah schools.

Individuals with developmental disabilities struggle to learn important life skills. This deficit impedes their ability to function in the community and live meaningful lives. Video prompting (VP) is an evidence-based practice that has been used to teach a wide variety of skills to individuals with disabilities. VP utilizes technology to create step-by-step videos to teach academic, social, vocational and other life skills This article extends the current literature on VP interventions to hygiene skills and investigates the efficacy, skill maintenance, social validity, and level of independence that can be achieved using VP to teach hygiene skills. Three participants with developmental disabilities were selected from a junior high school and were given a video prompting intervention on an iPad to improve hygiene skills. Hygiene skills that were taught included teeth brushing, teeth flossing, face washing and basic eye makeup application. All three participants reached and maintained mastery in each of their target skills. Social validity data indicated that using iPad delivered VP interventions was socially acceptable for teaching some hygiene skills. Not every participant was able to access the VP intervention completely independently. VP interventions are a viable option for teaching these crucial life skills to individuals with developmental disabilities.

Vocabulary growth during the preschool years is critical for language development. Preschool children with developmental disabilities often have more difficulty with learning and developing language, therefore making more errors in vocabulary. It is important to recognize what type of errors children are demonstrating, especially as it relates to receptive and expressive language abilities. This study explores the error patterns preschool children with developmental disabilities make during receptive and expressive single word vocabulary tests. A secondary analysis of preexisting data was conducted from a sample of 68 preschool children with developmental disabilities ranging in severity. Based on a coding system developed by the author, errors were classified according to type. The majority of the errors children made were classified as No Response types of errors, with the second most common error being Semantic Perceptual errors of receptive and expressive picture naming tasks. Understanding the types of errors preschool children with disabilities make will help to enhance their language and therapy needed to thrive as a learner, especially as they begin elementary school.

Background: Technological advancements in speech acoustic analysis have led to the development of spectral/cepstral analyses due to questions regarding the validity of traditional time-based measures (i.e., Jitter, Shimmer, and Harmonics-to-Noise-Ratio) in objectifying perturbations in dysphonic voices. Aim: This study investigated the validity of time-based measures in discriminating those with Friedreich’s ataxia (FA) from normal voiced (NV) peers when compared to cepstral-spectral measures. Method: A total of 120 sustained vowel phonations from an existing database of 40 participants (20 FA; 20 NV) of the vowels /ɑ/, /i/, and /o/ were analyzed to determine which set of variables (i.e., time-based vs. cepstral-spectral) better predicted group membership. Four variables of time-based measures (Jitter Local %, Jitter RAP, Shimmer Local %, Shimmer APQ11, and HNR) were analyzed via the freeware program PRAAT and compared to four cepstral-spectral measures (Cepstral Peak Prominence, Cepstral Peak Prominence Standard Deviation, Low/High Ratio Standard Deviation, and the Cepstral/ Spectral Index of Dysphonia) extracted from the Analysis of Dysphonia in Speech and Voice (ADSV) software program. Results: Findings from a discriminant analysis showed sensitivity and specificity results to be better for ADSV measures; 100% of those in the FA group were classified correctly (sensitivity), and 95% of members in the NV group were correctly identified (specificity) as compared to PRAAT (70% sensitivity and 85% specificity). Conclusions: Cepstral-spectral measures are much more accurate in discriminating between those with FA and NV peers as compared to time-based estimates.
