条件性恐惧 ( Conditioned Fear) 也称场景恐惧实验,是基于巴普洛夫条件反射而建立的一种经典的诱导焦虑反应模型的方法。它测定动物学习、记忆不悦经历(aversive experience)和环境暗示之间关联的能力。常用声音或光暗示作为条件刺激(conditioning stimulus,CS),以厌恶性刺激(如足电击)作为非条件刺激(unconditioning stimulus,US),二者配对出现。在条件性恐惧实验中动物会表现出一种特有的凝滞(freezing)状态,通过观察并记录动物的凝滞时间、凝滞总次数以及活动度等相关参数可以考察其学习记忆能力和焦虑状态。
Gene&I 在十多年的研究与服务过程中,积累了丰富的经验,并不断改进产品设计与用户体验,积极探索行为学的新发展方向!
Gene&I提供的条件性恐惧分析系统,采用的是动物轮廓识别技术、避免了图像噪点、雪花等干扰因素,并且提供了严格的时间判据,避免动物短时突动对于试验结果的影响,分析更准确。
