利兰·布雷德福（Leland P. Bradford,1905年7月12日——1981年5月1日)美国行为科学家，心理学家。感受性训练模式创始人，其主要贡献是提出群体行为：“感受性训练”- 实验室训练

敏感性训练也称T-团体训练（训练小组训练）或实验室训练，是美国行为科学家布雷德福（Leland Bradford）等人首创的一种训练方法。目的是通过受训者在共同学习环境中的相互影响，提高受训者对自己的感情和情绪、自己在组织中所扮演的角色、自己同别人的相互影响关系的敏感性，进而改变个人和团体的行为，达到提高工作效率和满足个人需求的目标。

敏感性训练的做法

敏感性训练的做法是把不同单位、不同级别、互不相识的管理人员、职工组成不超过15人为度的小组，进行1至2周的训练。在寻俩系中，参加的人员自由的讨论自己感兴趣的问题，自由地发表意见，分析自己地行为和感情，并接受对自己行为的反馈意见（批评或其他意见），从而提高对各种问题的敏感性。

敏感性训练的特点

敏感性训练的特点是：

1、无严密组织，无主席，无议题，无议程；

2、非定型的自由交谈，对有关现场的即所谓"此时此地"所发生的事情进行对话活动；

3、培训指导人员仅从旁协作，为学习过程提供方便，其使命是观察、记录、解释，有时诱导，扮演一种不引人注目的领导角色 。

训练一开始往往呈现一种使受训人员不知所措的局面。这时，有的人可能不耐烦，有的充满疑虑，有的思索，有的提议指定一个主席，有的提出各种问题。渐渐的展开了讨论，酝酿问题，交换意见，由此逐渐促成彼此间的认识和了解。
