The previous research shows that just noticeable difference (JND) values using the speech stimuli is about 5%. This is the case when the subjects have acquired size perception clue. The JND values is not necessarily small particularly for naive subjects. This parer presents a series of experiments to survey the characteristics of acquisition and retention of the perceptual cue for size discrimination task. We performed pretest, training session, posttest, and retention test using whispered words in the same procedure as reported previously. From the results of the first posttest, eight subjects was grouped into high performance (HP) group and low performance (LP) group. HP group performed the retention test after one month to confirm the JND values are almost the same. LP group was trained again to improve the JND values similar to the HP's values. As a result, given the sufficient acquisition of size perception clue, the JND values become the same as the values reported in the previous studies.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2014-05-17","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"47","bibliographicVolumeNumber":"2014-MUS-103"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":101364,"updated":"2025-01-21T11:16:06.270110+00:00","links":{},"created":"2025-01-18T23:46:58.812071+00:00"}
