Toilet activities of the elderly patients with dementia were observed focusing on care conditions and investigated based on Hull's drive reduction theory (behavior = drive × habit × incentive) and our self-awareness model (consisting of theory of mind, self-evaluation, and self-consciousness) to evaluate the association between self-awareness and toilet activities in patients with dementia and to explain the time when and the reason why a series of toilet activities as habit once acquired become unfeasible. If theory of mind is lost, awareness of one's desire and intention becomes vague, and toilet activities begin to collapse. Furthermore, if incentive disappears, one's intention hardly arises and toilet activities further collapse. If self-evaluation is lost, time sense fades, future goals based on the present time cannot exist, and behavior loses directivity. As a result, toilet activities collapse, and with a decrease in drive toilet activities cease.
观察老年痴呆症患者的如厕活动，重点关注护理条件，并基于赫尔的驱力降低理论（行为=驱力×习惯×激励）和我们的自我意识模型（包括心理理论、自我评价和自我意识）进行调查，评估痴呆症患者的自我意识与如厕活动之间的关联，并解释一系列如厕习惯一旦养成，为什么会变得不可行的时间和原因。如果心理理论丧失，对自己的欲望和意图的意识就会变得模糊，如厕活动开始崩溃。此外，如果激励消失，意图就很难产生，如厕活动进一步崩溃。如果自我评价丧失，时间感就会消失，基于当前时间的未来目标就无法存在，行为就会失去方向性。结果，如厕活动崩溃，随着驱力的减少，如厕活动停止。
