LEXICAL DETERMINATION PROBLEM ANALYZER, LEXICAL DETERMINATION PROBLEM ANALYSIS SYSTEM, LEXICAL DETERMINATION PROBLEM ANALYSIS METHOD, AND PROGRAM

PROBLEM TO BE SOLVED: To provide a lexical determination problem analyzer and the like capable of performing an investigation of a lexical determination problem together with measurement of response time, outputting a chart showing an analysis result, and easily and visibly displaying a result obtained by analyzing an answer together with a psychological state of an answerer.SOLUTION: A lexical determination problem analyzer presents a character string as target stimulus information after presenting prime stimulus information, and sequentially displays lexical determination problems of determining whether the character string makes sense or not as questions. The lexical determination problem analyzer also measures response time until the subject inputs an answer after target stimulus information is displayed, and stores the response time associated with the answer corresponding to each target stimulus information. The lexical determination problem analyzer has analysis processing for analyzing answers and response time obtained from a plurality of answerers and generating an analysis chart 70 as an analysis result, where the analysis chart 70 expresses a length of response time of an answer in response to target stimulus information by using a size of an arrow (draft) or the like, for example.
