條件性恐懼 ( Conditioned Fear) 也稱場景恐懼實驗,是基于巴普洛夫條件反射而建立的一種經典的誘導焦慮反應模型的方法。它測定動物學習、記憶不悅經歷(aversive experience)和環境暗示之間關聯的能力。常用聲音或光暗示作為條件刺激(conditioning stimulus,CS),以厭惡性刺激(如足電擊)作為非條件刺激(unconditioning stimulus,US),二者配對出現。在條件性恐懼實驗中動物會表現出一種特有的凝滯(freezing)狀態,通過觀察并記錄動物的凝滯時間、凝滯總次數以及活動度等相關參數可以考察其學習記憶能力和焦慮狀態。
Gene&I 在十多年的研究與服務過程中,積累了豐富的經驗,并不斷改進產品設計與用戶體驗,積極探索行為學的新發展方向!
Gene&I提供的條件性恐懼分析系統,采用的是動物輪廓識別技術、避免了圖像噪點、雪花等干擾因素,并且提供了嚴格的時間判據,避免動物短時突動對于試驗結果的影響,分析更準確。
