[Problem] To enable deciferring of the true feelings and latent
consciousness of a support recipient in cognitive behavioral therapy involving self-observation recording based on a behavior or operation by the support recipient, thereby realizing advanced feedback and behavioral therapy that could not be provided by conventional technology. [Solution] This mental information
input method which involves use of a computer in performing self-observation recording based on an behavior or operation by a support recipient, the method comprising: an operation acquisition step in which the computer acquires the behavior or operation by the support recipient as an incomplete operation history and acquires input information determined by the behavior or operation by the support recipient as a determined operation history; an observation
record accumulation step in which a self-observation
record including the incomplete operation history and the determined operation history is accumulated in an observation
record accumulation unit; a correlation feature analysis step in which a correlation feature analysis unit of the computer analyzes correlation between behavioral information and cognitive information of the support recipient on the basis of the self-observation record; and a
response generation step in which a
response generation unit of the computer generates response information to be provided to the support recipient in accordance with the analysis result in the correlation feature analysis unit.
