A Comparison And Item Analysis Of Responses Between Black Children And Language Delayed White Children On The Peabody Picture Vocabulary Test, Kevin N. Cole

Dissertations and Theses

The purpose of this study was to compare PPVT scores of Black children and language delayed White children in order to determine whether the patterning of errors can be differentiated between the two groups. The study involved twenty Black children and twenty language delayed White children between the ages of six years, six months, and seven years, six months. The subjects were from families of lower socioeconomic status. The White subjects were given the Utah Test of Language Development to establish degree of language delay.

The study was designed to determine whether either the language delayed White subjects or the …

An Investigation Of The Development Of The Phonemes /T/And /K/ In The Speech Of Preschool Children., Glenn Douglas Weybright

Dissertations and Theses

Research regarding children's instrumental articulation development has provided the speech clinician with schedules of speech sound development. These developmental tables list ages when specific phonemes are mastered by normal children. Such schedules tend to give the impression that certain sounds must be developed before others can occur. Menyuk (1972) has expressed a similar point of view regarding phonemes /t/ and /k/. She has hypothesized:

1. that phoneme /t/ must develop before phoneme /k/; and
2. that sound element initial /t/ is mastered at an earlier age than initial /k/. The present investigation was designed to operationally test the validity of Menyuk's observations. …

Age, Intelligence, And Socioeconomic Status Variance In Preposition Acquisition By Children, Georgie Hustead

Dissertations and Theses

Numerous linguistic studies have been done to substantiate the importance of prepositions in the English language. However, no normative studies have been done on the acquisition of expressing prepositions.

The purpose of this investigation was to determine if there were demonstrable trends which would indicate a need for normative data on the acquisition of twenty-six prepositions tested on the Expressive Preposition Test (EPT). The study set out to determine at what age levels a given percentage of the prepositions were expressively acquired and if the socioeconomic status (SES) of the child’s family would be a determiner as to the age …

The Frequency Of Retroflex /R/ Production In Elementary School Children, Vicki Barna Wood

Dissertations and Theses

In articulation treatment and diagnosis, it is essential to possess a thorough knowledge of what is “normal” as well as what is “defective” articulation. The /r/ phoneme is one of the most frequently occurring and most commonly defective sounds. There are two different tongue positions for the /r/ phoneme described in the literature (retroflex and central hump), with many assumptions about which tongue position is “normal” or “most common.” None of these assumptions, however, are based on empirical data.

The purpose of this study was to provide some normative data regarding which of the two tongue positions is most common …
