Changes In Scholastic Achievement And Intelligence Of Indian Children Enrolled In A Foster Placement Program, Linda Ouida Willson Jan 1973

Changes In Scholastic Achievement And Intelligence Of Indian Children Enrolled In A Foster Placement Program, Linda Ouida Willson

Theses and Dissertations

This study examines the long-term effects of the Indian Placement Program on the enrolled students' scholastic achievement as measured by standardized tests given in the schools. It also examines intelligence test scores and changes in them during years in the Program. The following effects on achievement were also examined: sex, age and grade at initial placement, and the child's adjustment as measured by number of foster homes in which he had been placed.

A speech analysis-synthesis system was used to manipulate variance of fundamental frequency and a mechanical rate changer was used to manipulate speech rate. The synthesized and altered voices were tested for realism. Synthesized voices were mistaken for normal 50% to 58% of the time and rate-changed voices were mistaken for normal 78% of the time. Additional studies were conducted to test the effects of these acoustical manipulations on the adjective ratings judges made of speakers. Variance of intonation was increased and decreased by 50% for eight speakers. There was a significantrend for increased intonation to cause voices to be rated …

Utterances of two adults males were analyzed and synthesized by a fast Fourier Transforms method. Each of the two voices was synthesized in each of the twenty‐seven combinations of three levels each of rate, mean , and variance of (a total of fifty‐four “voices” generated from two). The effects of the rate, mean , and variance of manipulations, the interactive effects of rate and variance of , and the effects due to speaker were all statistically significant predictors of personality ratings given the voices. They accounted for 86%, 4%, 3%, 2%, and I% of the …
