Because of the extent of her withdrawal, the subject was conditioned in a laboratory setting and received tokens for speaking loudly enough to operate a voice\u2010operated relay. Conditioning at first consisted of saying 100 monosyllabic words, with the possibility of reinforcement on each word. Later, the subject was required to say a polysyllabic word, and finally, five or six words per token. The subject was shaped to speak with normal loudness in the laboratory, and generalization to a reading situation in the laboratory was measured and observed to occur, at first for a few minutes, and later for a longer period. Generalization to a reading situation in the classroom did not occur, but the subject's voice loudness also increased in the classroom when several new reinforcement contingencies were put into effect there.<\/jats:p>","DOI":"10.1901\/jaba.1974.7-461","type":"journal-article","created":{"date-parts":[[2006,3,2]],"date-time":"2006-03-02T15:59:31Z","timestamp":1141315171000},"page":"461-471","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["THE MODIFICATION AND GENERALIZATION OF VOICE LOUDNESS IN A FIFTEEN\u2010YEAR\u2010OLD RETARDED GIRL1"],"prefix":"10.1002","volume":"7","author":[{"given":"Donald A.","family":"Jackson","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.
