中文摘要 | 本研究進行辨識吶吃語音訓練實驗,目的在探究知覺學習效果以及辨識障礙語音熟悉效應的可能心理機制。實驗方法是比較三組受試者在訓練前後聽辨一位成年腦性麻痺女性所唸出的單音節與雙音節詞(單詞)的清晰度。實驗組受試者在訓練過程中進行單音節配對選擇作業,其中操弄單音節配對的知覺混淆程度,分成混淆組與非混淆組。結果發現在前測中辨識表現沒有差異的三組受試者,在後測及再測的表現上呈現出顯著差異:接受混淆配對的受試者在訓練後具有顯著進步,而接受非混淆配對的受試者進步量不明顯,但比未接受訓練的控制組佳。然而這樣的學習效果只出現在單音節刺激的辨識上。此結果顯示知覺學習能增進辨識障礙語音的清晰度,且學習過程中注意力選擇運作將顯著影響學習效果。 |
英文摘要 | In the present study, an intensive laboratory training was carried out to investigate the effects of speech perceptual learning and the underlying mechanisms of speaker familiarity effect. Three groups of subjects were tested with the lists of bisyllabic words and monosyllables produced by a Chinese-speaking woman with cerebral palsy before and after training. The forced-choice paradigm was applied in the training task, and confusability among syllable pairs was manipulated for the two learning groups. The control group received no training. Results showed that performance of the three groups was the same prior to training, significant differences on the post-test were observed: The group trained with more easily confused pairs performed much better than the control group. However, the training effect only appeared on the identification for monosyllabic stimuli. These findings indicated that laboratory training could improve the intelligibility of dysarthric speech, and the allocation of attention during training course significantly affected the performance of subjects. |
