The Frankfurt Adaptive Concentration Test (FACT-2) is a computer-based testing method for determining the individual concentration capacity by means of discrimination tasks. The proband has to discriminate continually between geometric target and nontarget items as accurately and quickly as possible. Both, target items as well as non-target items require a specific reaction button. Thus a directed attention is required for all items. The first edition of the test was introduced in 1997 by Moosbrugger and Heyden, the second edition 2005 by Moosbrugger and Goldhammer, each at Goethe University Frankfurt. == Discrimination Items == There are four types of items, the so-called "Frankfurt Discrimination Items": Circle or square, each with two or three points in the middle. Each type is composed of two items that differ in the arrangement of dots. The items "circle with 3 points" and "square with 2 points" are defined as targets, the items "circle with 2 points" and "square with 3 points" are defined as non-targets. Thus, there are thus two stimulus dimensions, namely, the geometric shape and the number of points . The third dimension, the arrangement of points, is irrelevant to the discrimination task. Target items require to press the key "1" and non-target items require the key "0". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Frankfurt Adaptive Concentration Test」の詳細全文を読む スポンサード リンク
