下列哪一项不属于简单的、人生来就有的反射活动？（　　）

A．谈虎色变

B．缩手反射

C．膝跳反射

D．眨眼反射

答案

简单反射与复杂反射的本质区别是否有大脑皮层的参与．没有大脑皮层参与的，神经中枢在大脑皮层以下的反射是简单反射，反射的神经中枢在大脑皮层上的反射是复杂反射．

简单反射是指人生来就有的先天性反射．是一种比较低级的神经活动，由大脑皮层以下的神经中枢（如脑干、脊髓）参与即可完成．膝跳反射、眨眼反射、缩手反射、婴儿的吮吸、排尿反射等都非条件反射．缩手反射、膝跳反射、眨眼反射．这种反射活动是人与生俱来、不学而能的，因此属于简单件反射．

复杂反射是人出生以后在生活过程中逐渐形成的后天性反射，是在非条件反射的基础上，经过一定的过程，在大脑皮层参与下完成的，是一种高级的神经活动，是高级神经活动的基本方式．谈虎色变，是出生后才有的，是在非条件反射的基础上，经过一定的过程，在大脑皮层参与下完成的复杂反射．

故选：A．
