A summer room, where, to anyone of normal perceptions, nothing passed at all.

Interestingly enough, the impaired subjects made entirely normal perceptions in this task.

He said that in normal perception, only "here" was perceived completely, instantaneously, and directly.

He had never realised so clearly that normal human perception is a form of blindness.

It is outside our normal perception of space and time.

This was not quite the daylight of normal perception.

Now he was back in the world of stunted, normal human perceptions.

They had succeeded in enlarging the parameters of their normal perception.

In normal perception these are recognised as a single three-dimensional object.

By the time they regain their normal perception, we will have long been gone.
