This study investigated the incidence of peripheral hearing loss in sickle cell anemia and the possibility of central auditory nervous system involvement. Nine Black subjects with sickle cell disease and nine with normal hemoglobin were administered an auditory test battery. There appeared to be no correlation between number of crisis episodes, duration of symptoms, severity of symptoms, and audiologic manifestations. Acoustic reflex testing suggested the possibility of "aired neural function in the sickle cell group. Whether impaired function was due to peripheral VIIIth nerve or to central brain stem involvement could not be determined. Results of the central auditory test battery suggested the possibility of impaired or reduced central auditory function in subjects with sickle cell anemia.

Intervals of specified fluent verbal behavior of two stutterers received response-contingent positive stimulation in the form of an accumulating points system, Assessment was made o the effect of experimental manipulation on the frequency of fluent speech intervals as well as on the frequency of subject-identified stuttering behaviors observed during the experimental session. The results indicated significant change in fluent interval frequency in the spontaneous speech of one subject. Effect of the experimental contingency was not demonstrated in the oral reading of a second subject. Stuttering. behavior data indicated that an indirect effect of the positive stimulation can change the frequency of behavior not being contingently stimulated.

This thesis examines the symbolism of thirty-five slave songs that existed in the pre-Civil War South in the United States in order to gain a more profound insight into the values of the slaves. The songs chosen were representative of the 300 songs reviewed. The methodology used in the analysis was adapted from Ralph K. White's "Value Analysis: The Nature and Use of the Method." The slave songs provided the slaves with an opportunity to express their feelings on matters they deemed important, often by using Biblical symbols to "mask" the true meanings of their songs from whites. The major values of the slaves as found in their songs were independence, justice, determination, religion, hope, family love, and group unity.
