摘要

本研究旨在探討不同類型的缺點組合（「V，X」、「X，8」和「／，8」）、配速（21s、23s、27s與無配速）與分類水準（分成3類和4類）對於偵檢績效與心智負荷的效應，共徵募15位受試者參與實驗。結果發現（1）分類水準對於命中次數有顯著效應，並以分成3類的正確分類次數顯著高於分成4類；（2）缺點組合對偵檢時間、正確分類次數與心智負荷皆有顯著的效應；（3）作業配速對偵檢時間與心智負荷有顯著的效應，大致上以無配速優於其他配速，但27s的配速條件下心智負荷較低，且偵檢時間卻與21s與23s沒有顯著差異；（4）缺點組合與配速條件對於偵檢時間與正確分類次數有顯著的交互作用，在低辨識度的缺點條件下（「V，X」），不同的配速條件間有顯著差異，而在高辨識度（「X，8」和「／，8」）無配速顯著的優於其他配速條件。證實在低辨識度的缺點條件下，所設定的配速條件才會影響時間績效，換言之，實務上的作業配速設計需考量產品缺點的辨識度。

This study examines the effect of different types of defect combinations (”V, X”, ”V, 8”, ”/, 8”), pacing (21s, 23s, 27s, and no pacing included), and classification levels (divided into three classification and four classification) on inspection performance and mental load. Fifteen participants were recruited for this experiment. The result shows that (1) the level of classification has a significant effect on the hit time. Type three is relatively higher than type four, (2) Defect combination has a significant impact on inspection time, accurate classification times and mental load, (3) The task pacing has a significant influence on detection time and mental load. Non-paced inspection is superior to any other pace, and the 27s pacing has a lower record on mental load and inspection time, but has less difference compared to the 21s and 23s; (4) A significant interaction effect was found between the defect combination together with paced condition on inspection time and accurate classification times. Under low defect condition recognition (”V, X”), a significant difference was found among different pacing conditions whereas under high recognition (”X, 8” and ”/, 8”), the non-pacing is significantly superior to any other pacing conditions. It was proved that under low defect condition recognition the set pacing condition has an impact on time performance. That is, the pacing design in practice should take product defect recognition into account.
