PROBLEM TO BE SOLVED: To provide a new index for evaluating a degree of difficulty of vocabulary comprehension in a vocabulary learning process of an infant.;SOLUTION: The device for evaluating a difficulty degree of infant vocabulary comprehension includes: a logistic function approximation section; a learning day-age calculating section; and a learning period calculating section. The logistic function approximation section uses a learning time xi and a learning ratio f(xi) of vocabulary i for a vocabulary learning process of multiple infants as input in order to approximate a relationship of the learning time xi and the learning ratio f(xi) for each vocabulary i in a logistic curve. The learning day-age calculating section uses the logistic function to obtain an α% learning day-age and a β% learning day-age which is smaller than the α. The learning period calculating section uses the α% learning day-age and the β% learning day-age as input and calculates the learning period of the vocabulary i in order to output the learning period as the comprehension difficulty degree of the vocabulary i.;COPYRIGHT: (C)2014,JPO&INPIT
