THE ANALYSIS AND CONTROL OF INFANT VOCAL AND MOTOR BEHAVIOR.
SHEPPARD, WILLIAM CLARENCE, JR.
IN EXPERIMENT 1, DEVELOPMENTAL CHANGES IN THE PROSODIC FEATURES OF INFANT VOCALIZING WERE STUDIED WITH NOVEL ELECTRO-ACOUSTIC TECHNIQUES. COMPLETE AND CONTINUOUS RECORDINGS OF ALL THE VOCALIZATIONS OF TWO INFANTS DURING THE FIRST FIVE MONTHS OF LIFE WERE COLLECTED AND SYSTEMATICALLY SAMPLED FOR ANALYSIS. COMPOSITE STATISTICS, DESCRIBING THE THREE PROSODIC FEATURES OF THE VOCALIZING IN EACH SAMPLE (FUNDAMENTAL FREQUENCY, RELATIVE AMPLITUDE, AND DURATION), WERE PLOTTED SEPARATELY AS A FUNCTION OF AGE AT THE TIME OF SAMPLE. PARAMETER VALUES AND TRENDS IN THE PROSODIC FEATURES OF INFANT VOCALIZATION ARE REPORTED. IN EXPERIMENT 2, CONTROL OF INFANT VOCAL AND MOTOR OPERANT BEHAVIOR WAS STUDIED DURING AN EXPERIMENT CONDUCTED IN THE INFANT'S HOME. DAILY EXPERIMENTAL SESSIONS WERE HELD FROM THE TIME THE SUBJECT WAS 10 DAYS OLD UNTIL HE WAS THREE MONTHS OLD. VOCALIZATION AND LEG KICK WERE STUDIED UNDER A NUMBER OF CONDITIONS. FOUR REINFORCERS WERE EMPLOYED--A RECORDING OF THE MOTHER'S HEARTBEAT, A VIBRATOR TAPED TO THE INFANT'S PALM, TWO FLASHING LIGHTS, AND A RECORDING OF THE MOTHER'S VOICE. SCHEDULE CONTROL OVER RESPONDING AND DIFFERENTIAL RESPONDING UNDER DISCRIMINATIVE CONTROL FOR BOTH VOCAL AND MOTOR OPERANTS IN AN INFANT LESS THAN THREE MONTHS OF AGE WAS ACHIEVED. THIS DISSERTATION APPEARS IN COMPLETE FORM IN "SUPPLEMENT TO STUDIES IN LANGUAGE AND LANGUAGE BEHAVIOR, PROGRESS REPORT V," SEPTEMBER 1, 1967, PUBLISHED BY THE CENTER FOR RESEARCH ON LANGUAGE AND LANGUAGE BEHAVIOR, 220 EAST HURON STREET, ANN ARBOR, MICHIGAN 48108.
