人與人之間互動如要維持彼此尊重、讓彼此感到舒適，很重要的關鍵，要能領域(Territory)是個虛擬，卻實質影響人與人之間互動、生存與感到自在的。領域從空間領域開始定義，也就是物理空間的地盤，物品領域則是指物品的所有權，同理可知，想法領域(perspective territory)就是指想法上的地盤，想法領域侵犯最常發生的情境在於與人產生爭論之際，當兩方意見不同時，視為一種想法上的地盤被侵略。
　　收案族群為失智症病人，因疾病關係病人可能出現遺忘或錯認情形，照顧者常從旁糾正，故雙方想法衝突，人類受文化與教育影響會採協商溝通，但是失智症病人可能因疾病無法以言語表達需求，轉而以非語言方式表達，也就是所謂的躁動行為(agitation behavior)。20-50%失智症病人有躁動行為表現，照顧者疲於應付，本研究目的為了解想法領域侵犯對失智症病人的影響，做為失智症照護方式之改善。
　　本研究採取實驗組與對照組實驗介入前後對照方式，實驗共兩項，第一項實驗為牛頭不對馬嘴實驗，實驗設計為觀看影像與聲音違和的影片，以產生想法領域上的衝突落差，第二項實驗為指鹿為馬實驗，為問答形式，回答後立即以〝X〞影像與錯誤音效產生否定刺激，實驗過程變項蒐集心跳變異程度(Heart rate variability, HRV)與身體壓力中心改變(center of pressure variability, COPV)作為躁動行為評估指標。研究假設為想法領域受侵犯時失智症病人心跳變異比認知健康者低、身體壓力中心變異大。
研究結果發現實驗一僅認知健康組心跳變異上升，可能為研究設計無法產生適當想法領域侵犯刺激及研究流程設計設計問題，此可作為未來研究改善之參考；實驗二實驗效度高，失智症組比認知健康組身體壓力中心變異大，符合部分研究假設，顯示想法領域受侵犯時失智症病人躁動行為較認知健康者顯著，照護時應注重病人之領域建立。

Background:Territory refers to the defense area in space or belief. Violation of territory will result in defense behavior. The theory and practice are based on animal behavior, and territory is a unique form of human beings. This study is focus on dementia patients whose behavior and cognitive often negatived by caregiver due to characteristic of disease. Meanwhile, it is a sort of violation of territory for dementia patients. According to clinical observation, violation of territory is closely related to agitated behavior. Hence, the purpose of the research is to discuss the effect of territory offenses and agitated behavior in dementia patients.

Method:There were normal control group and dementia group respectively. A cross-over design was adopted, including two tests. Film and questions were given in order to simulate the situation of violation of territory. Test 1-This test is to create cognitive conflict by watching video stream which the images doesn’t match the sound. Test 2 - Question and Answer is conducted in test 2 and the video would immediately display the false sign “X” and sound. Observe patients’ behaviors while the false sign and sound generated. Heart rate variability (HRV) and center of pressure variability (COPV) were applied to evaluate agitated behavior. HRV monitor and Wii Balance Board were utilized to measure physical and behavior orientation of aggressive and non-aggressive behavior respectively.

Results:The dementia patients are prone to generate agitated behavior when their territory is violated. That is, the dementia patients are more aggressive than others which indicate higher changes of COPV mean that non-aggressive behavior happened intensively.

Conclusion:According to Sigmund Freud’s personality construct theory, super-ego and ego are constrained by ethical standards. Communication and negotiation are methods used by super-ego and ego for achieving a balance while they faced violation of territory. As for the dementia patients, they behave directly without cover owing to the return of Id on personality development. Thus, they are relatively easy to agitate when encountering violation of territory. As a result, the dementia patient needs more respect in different area compare with normal people. And this can adopted to improve care in the further.
