Description
This thesis investigated the impact of word complexity as measured through the Proportion of Whole Word Proximity (PWP; Ingram 2002) on consonant correctness as measured by the Percentage of Correct Consonants (PCC; Shriberg & Kwiatkowski 1980) on the spoken words of monolingual Spanish-speaking children. The effect of word complexity on consonant correctness has previously been studied on English-speaking children (Knodel 2012); the present study extends this line of research to determine if it can be appropriately applied to Spanish. Language samples from a previous study were used (Hase, 2010) in which Spanish-speaking children were given two articulation assessments: Evaluación fonológica del habla infantil (FON; Bosch Galceran, 2004), and the Spanish Test of Articulation for Children Under Three Years of Age (STAR; Bunta, 2002). It was hypothesized that word complexity would affect a Spanish-speaking child’s productions of correct consonants as was seen for the English- speaking children studied. This hypothesis was supported for 10 out of the 14 children. The pattern of word complexity found for Spanish was as follows: CVCV > CVCVC, Tri-syllables no clusters > Disyllable words with clusters.

Description
The purpose of this study was to explore the effects of word type, phonotactic probability, word frequency, and neighborhood density on the vocabularies of children with mild-to-moderate hearing loss compared to children with normal hearing. This was done by assigning values for these parameters to each test item on the Peabody Picture Vocabulary Test (Version III, Form B) to quantify and characterize the performance of children with hearing loss relative to that of children with normal hearing. It was expected that PPVT IIIB scores would: 1) Decrease as the degree of hearing loss increased. 2) Increase as a function of age 3) Be more positively related to nouns than to verbs or attributes. 4) Be negatively related to phonotactic probability. 5) Be negatively related to word frequency 6) Be negatively related to neighborhood density. All but one of the expected outcomes was observed. PPVT IIIB performance decreased as hearing loss increased, and increased with age. Performance for nouns, verbs, and attributes increased with PPVT IIIB performance, whereas neighborhood density decreased. Phonotactic probability was expected to decrease as PPVT IIIB performance increased, but instead it increased due to the confounding effects of word length and the order of words on the test. Age and hearing level were rejected by the multiple regression analyses as contributors to PPVT IIIB performance for the children with hearing loss. Overall, the results indicate that there is a 2-year difference in vocabulary age between children with normal hearing and children with hearing loss, and that this may be due to factors external to the child (such as word frequency and phonotactic probability) rather than the child's age and hearing level. This suggests that children with hearing loss need continued clinical services (amplification) as well as additional support services in school throughout childhood.

Description
Preschoolers' vocabularies are an important component of their receptive and expressive language skills. This study was designed to catalog preschoolers' expressive vocabularies to provide an accurate estimate of how many words and which words seven preschoolers knew. In this study a LENA digital recorder was used to record language samples of the children (age range 40 months to 69 months) over 4-6 days. Their language samples were transcribed and individual root words were extracted. The children spoke an average of 1,698 unique words (range 1,522 \u2014 1,957 words). There were 539 words produced by all of the children in the study as well as 820 words produced by 6 of the 7 children. These data provide preliminary information that will be useful for designing a larger, more comprehensive study of children's vocabulary with the goal of teachers and speech-language pathologists being able to use this information to determine if a child's vocabulary is smaller than other children when they enter elementary school. This can inform assessment and intervention decisions as well as provide guidance to preschool curriculum developers.
