Five digit test (FDT) is appropriate both for English and non-English speakers, and competent readers and illiterate subjects. The cognitive requirements of doing the tasks are very low. The subject need to name digits 1 to 5 and recognized perceptual pattern of 1 to 5 elements (Hsieh & Tori, 2007).
It is divided into four parts. Each part contains 50 items. The items are groups of digits or stars printed inside the frames. The digits can either be named as the number printed in the frame (two 5s are read as “five”), or counted how many digits are in the frame (two 5s are counted as “two”). Part 1 and part 2 measure processing speed. Part 3 and part 4 measure response inhibition. In part 1, a subject reads groups of digits. In part2, the subject counts groups of stars. In part 3, the subject counts conflictive items and items and avoids naming them (if two 5s are presented, the correct response is “two” and not “five”). In part 4, the subject needs to switch between counting (80% of the items) and naming (20% of the items) the number, whenever the item has a darker frame. For each part, test scores are the amount of performance time in seconds plus the total of errors made (Hsieh & Tori, 2007; Verdejo, Toribio, Orozco, Puente, & Perez-Garcia, 2005).

  1. 我沒看到究竟FDT評量那些注意力？更不用說各種注意力指標如何計算了。

  2. 我在上篇已提到有看到林昭的資料，她有提到FDT評量注意力能力，但我仍然要看到原版FDT手冊，我才能確實到底什麼是正確的計算方式。
