N400 and short speech stimuli.

N400 and short speech stimuli. Clin Linguist Phon. 2019 Jul 25;:1-8 Authors: Munivrana Dervišbegović B, Mildner V Abstract In some children who have cochlear implants (CI), the expected speech-language outcome is not achieved despite fulfilment of requirements for its successful use. This may be attributed to processing difficulties at higher levels of the auditory pathway. The aim of this study was to investigate the processing of speech stimuli at the auditory-cortex level in 20 children aged 8 to 10 years who have a hearing impairment and have been using cochlear implants, by means of cortical auditory evoked potentials (CAEP). The children were divided into two groups, depending on the outcome: 10 successful implant users and 10 unsuccessful implant users, whose speech-language development has not progressed as expected. The control group comprised of 10 age-matched children with typical hearing and speech-language development. Two double consonant+vowel syllables (CVCV) were used as stimuli, presented in an oddball paradigm that required the subjects to react consciously. Latencies and amplitudes of CAEP waves were measured. In addition to the waves that typically occur in CAEP and reflect auditory processing at the level of the auditory cortex, N400 wave (associated with semantic processing) was recorded in the normally hearing group and successful CI users, but not in the unsuccessful CI users. Additionally, successful CI users and control...

When I boarded an 8-hour international flight home from a language neurobiology conference a this past August, I anticipated getting some major work done. If I was lucky, I could also catch a nap. But my plans quickly changed when assigned seating fates intervened. Thanks to a technical snafu, I got the last remaining seat on the plane. As I walked down the aisle, a flight attendant stopped me. She warned that my seatmate—a young boy with nonverbal autism prone to disruptive behaviors—might make the flight difficult, but that there were no more available seats. When I sat down, the boy’s father preemptive...

Hearing impairment is one of the most common disabilities in the UK and globally. Worldwide, 60% of cases are thought to be preventable and fewer than 10% globally have access to the hearing support they need. Childhood hearing impairment can impact on development, speech, language, auditory processing, listening skills, behaviour, self-esteem, quality of life and learning. Our responsibility as clinicians is to prevent developmental impairment in these areas and ensure children with a hearing impairment have the same life chances as children who hear well.

As a speech-language pathologist, you talk to patients and their caregivers, to colleagues, and to collaborators, and then you talk to yourself while making notes on the all previously listed interactions. Therefore, you’d think an extrovert would be the ideal personality for the job. After all, SLPs devote their careers to promoting better communication, so they must enjoy communicating, right? Not always. As it turns out, a special and not-so-rare species of introverted SLPs quietly works in the profession. The term “introverted SLP” should not come off as an oxymoron. When talking to my peers for this ...

Conclusion The findings suggest perceptual processing differences associated with acoustic parameters of fundamental frequency and 1st formant perturbations in PD. These findings extend our previous results, indicating that different patterns of compensation to pitch and 1st formant shifts may reflect a combination of sensory and motor mechanisms that are differentially influenced by basal ganglia dysfunction.

Question: I’m a private-practice, ASHA-certified speech-language pathologist who is three months pregnant. I have been treating a child in her home, but I want to discontinue services to the child because no one in the family has been vaccinated for the measles. Can I do so or would it be considered client abandonment? More than 1,150 measles cases occurred in more than 30 states in the U.S. in 2019, and most of those cases involved unvaccinated people, according to the U.S. Centers for Disease Control and Prevention (CDC). Measles is highly contagious and there is no cure. Measles in pregnant women may have serious ...

Conclusion: Deaf children with cochlear implants who are performing well on linguistic and auditory tests can still experience serious limitations in desired functioning. Our findings suggest that a capability approach may reveal aspects of what is being achieved through rehabilitation that might otherwise remain unnoticed, and that could help to further improve the well-being of our patients.IMPLICATIONS FOR REHABILITATIONOverall, children with cochlear implants appeared disadvantaged in certain capability areas, like accessing information, communication, social participation, and participation in school.It may be worthwh...

When speech-language pathologists work with middle and high school students, we can focus our services more on real-life topics—both in addressing academic skills and social interactions. Students at this level also tend to take more ownership of their sessions by recognizing areas needing more attention, helping set goals, and identifying strategies that work best for them.

ABSTRACT Anterior open bite (AOB) is characterized by the lack of overlap or contact between maxillary and mandibular incisors, while the posterior teeth are in occlusion. Correction of this malocclusion is challenging due to difficulties in determining and addressing the etiologic factors, and the high relapse rate. A multidisciplinary approach may be necessary, with participation of Orthodontics, Surgery and Speech Therapy, to achieve adequate esthetic and functional results for long term stability. The present paper discusses the treatment options for AOB, their advantages and implications.RESUMO A mordida aberta anteri...
