Laryngeal-Level Amplitude Modulation In Vibrato, Lorie C. Reese

Theses and Dissertations

Research in vocal vibrato has established that vocal tract filtering is primarily responsible for the amplitude modulation (AM) present in Western classical vibrato. Using electroglottography (EGG) and the EGG speed quotient, which is sensitive to fluctuations in the amplitude of vocal fold vibration, AM was detected at the laryngeal (source) level, in addition to the subsequent AM which results from vocal tract filtering. Seventeen classically-trained opera singers sang vowels in three pitch and loudness conditions. EGG and microphone measurements of FM and AM and their rates, extents, and periodicity were made. Airflow was also measured, and the samples were rated …

Recognition Of Facial Expressions Of Six Emotions By Children With Specific Language Impairment, Kristen Diane Atwood

Accuracy Of Automated Developmental Sentence Scoring Software, Carrie Ann Judson

Theses and Dissertations

Developmental Sentence Scoring (DSS; Lee 1974) is a well established, structured method for analyzing a child's expressive syntax within the context of a conversational speech sample. Automated DSS programs may increase efficiency of DSS analysis; however the program must be accurate in order to yield valid and reliable results. A recent study by Sagae, Lavie, and MacWhinney (2005) proposed a new method for analyzing the accuracy of automated language analysis programs. This method was used in addition to previously established methods to analyze the accuracy of a new automated DSS program, entitled DSSA (Channell, 2006). Previously collected language samples from …

The words were then presented to 20 normally hearing subjects at 14 intensity levels (-10 to 16 dB HL) with 2 dB increments. Psychometric function slopes were calculated using logistic regression. Twenty-eight words with steep psychometric function were selected and digitally adjusted to match the mean …

Assessing Effects Of Iq On Sociable And Withdrawn Behaviors In Children With Language Impairment, Amanda Lyn Bradshaw

Theses and Dissertations

The purpose of this study was to determine the influence of IQ on subtypes of sociable and withdrawn behaviors in children with language impairment (LI). Research has suggested that children with LI are more likely to experience difficulty with social interaction than their typically developing peers (Brinton & Fujiki, 1999; Rice, 1991). The Teacher Behavior Rating Scale (Hart & Robinson, 1996) was used to compare sociable and withdrawn behaviors in 19 children with LI and 19 children with typically developing language. IQ scores for each participant were obtained by administering the Universal Nonverbal Intelligence Test (Bracken & McCallum, 2003). These …

Influence Of Age On Auditory Gating, Ginny Marissa Smith

Theses and Dissertations

This study utilized paired tones at 1000 Hz with a 500 ms interpair interval and a 10 s interstimulus interval to assess sensory gating. Forty-two participants, ranging from 3-72 years of age were used to observe maturational changes in amplitude, latency, and suppression ratios of the P50 waveform. Previous research has shown that in normal adults the amplitude in response to the second of the paired tones is significantly suppressed compared to the amplitude in response to the first tone. The current study showed amplitude decreased with age to middle adulthood, where it increased slightly to later adulthood. Latencies decreased …

The Relationship Between Social Behaviors And Working Memory In School-Age Children With Language Impairment, Melanie Diane Javid

Theses and Dissertations

Children with language impairment (LI) have notable social problems (Brinton & Fujiki, 2004). Research has shown that children with LI often have deficits in working memory (Kirchner & Klatsky, 1985; Stark, Poppen, & May, 1987). The relationship between working memory and social behaviors has not been clearly defined. This study examined this relationship in children with LI and typical age-matched peers by asking participants to repeat nine nonwords and correlating these results with social behaviors as rated by teachers. The Teacher Behavior Rating Scale (TBRS; Hart and Robinson, 1996) was used to compare social behaviors of 19 school-age children with …
