    運動の外在・内在フィードバックモデルを言語運動に適用し, 言語課題で熟知度の低いことばの朗読はDAF効果を受けやすく, 練習や語の有意味性によって熟知度が高くなるほど, フィードバックが内在化してDAF効果が小さいであろうと予想して, 実験的検証を試みた.小学6年生の男女60名を均質な3群に分け, W群は単語, NS群は無意味綴り, NSP群は練習した無意味綴りの刺激語を朗読させた.流暢さの指標として1秒当たりの正しいモーラ数〈CMR〉をとり, DAF効果を〈1-DAFのCMR/NAFのCMR〉と定義した.
    被験者全体では熟知度の高い単語はDAF効果は小さく, 熟知度の低い無意味綴りはDAF効果は大であった.無意味綴りの練習群と非練習群とのDAF効果には, 被験者全体としては有意差がなかったが, 男女間では男子は練習群が非練習群よりDAF効果が有意に大きく, その逆に女子では練習群が非練習群よりDAF効果が小さくなる傾向がみられた.DAF効果には性差があり, 無意味綴り練習群と単語群に有意に認められた.

    The palatalized articulation for the dental and alveolar sounds has been reported as a type of articulation errors in the cleft palate speech. In the present paper, articulatory tongue gestures for this particular type of error were observed by the use of dynamic palatograph and cineradiograph.
    The subjects were 9 postoperative cleft palate patients with this type of articulation error, 5 males and 4 females, ranging from 5 to 23 years old. Among the 9 subjects, 2 were observed by cineradiograph and 8 by dynamic palatograph.
    The result revealed the tongue gestures were characterized by the articulatory contact of the back of the tongue, instead of the tip or the blade, to the posterior end of the hard palate. The tongue-palate contact was clearly different from that for the normally palatalized /s/ which is represented as [∫] in Japanese. Sound spectrograms of the fricative sound produced by this abnormally palatalized articulation showed a marked decrease in the noise energy in the high frequency range as compared to the [s] or [∫] . The results supported the previous report where characteristic features of this articulation error were described mainly by auditory analysis and by limited visual observations from the mouth opening.
    Articulation training was administered to the patients in order to replace the faulty articulation by the correct gestures for the dental and alveolar sounds. The tongue-palate contact pattern which was nearly identical to that in normal subjects was observed when the patient reached the clinically acceptable goal.

    The purpose of this paper is to discuss the possibility of application of ultrasonic technique to observe tongue shape. One of the advantages of ultrasonic technique is harmlessness to the human subject. Beside this, the frontal section of the tongue which is the difficult object for ordinary X-ray photo can be visualized. Sagittal contours of the tongue for five Japanese vowels observed by this method are well corresponding to those by X-ray technique. Contours of the frontal section at around the tongue root show a groove formation during /i/, /e/, and /o/ production.
    For all of these three vowels, the genioglossus muscle shows higher activity. Therefore, the observed groove may be representing the inserting portion of the genioglossus muscle.
    Since the apparatus we used in this study is designed and developed for the clinical purpose, for example to examine the thyroid tumor, the data we got had limited informations especially, the visualized area was narrow. But if we can use the sector type porbe instead of the linear type, we might have the wider area to be observed.
    The ultrasonic apparatus would be appropreate for observation of the tongue shape.

    はじめに顎顔面頭蓋 (上顎骨・下顎骨) における正常な成長過程がどのような機序で行われているか, さらに口唇・口蓋裂の形成術による侵襲および瘢痕による緊張が, 術後の顎顔面頭蓋の成長にどのような影響を与えているか, について今までに報告されている研究結果に基づいて説明した上で, 顎発育の矯正学的管理, すなわち矯正治療について述べてみたい.
