PROBLEM TO BE SOLVED: To objectively measure the concentration level when a subject is given with a load of mental work.SOLUTION: A presentation device 20 presents a recognition object to a subject. An input device 30 allows the subject to input an answer to a work problem as a mental work relevant to the recognition object. The work problem comprises: a work to extract predetermined plural kinds of recognition elements included in the recognition object; and a work to select a choice suitable to the recognition element extracted from the recognition object from the plural combined choices preset for each recognition element. An evaluation device 10 includes a work storing section 122 that stores an answering time from a point when a recognition object is presented on the presentation device 20 to a point when an answer is input on the input device 30 as work information. Also, the evaluation device 10 includes an evaluation calculation section 110 that calculates an evaluation value of the concentration level of the subject using a statistical amount of the work information stored by the work storing section 122 while plural recognition objects are presented on the presentation device 20. |
