On the Waterfall Illusion

We adore chaos because we love to produce order. (M. C. Escher)

Are you really sure that a floor can’t also be a ceiling? (M. C. Escher)

He who wonders discovers that this in itself is wonder. (M. C. Escher)

Only those who attempt the absurd will achieve the impossible. I think it’s in my basement… let me go upstairs and check. (M. C. Escher)

I am always wandering around in enigmas. There are young people who constantly come to tell me: you, too, are making Op Art. I haven’t the slightest idea what that is, Op Art. I’ve been doing this work for thirty years now (M. C. Escher)

On Perception

Look at the images below. Which image do you see first in each of four images in the gallery below? (To help, there is a question below each image.)

Look at them again. Can you see the other?

Perception: The recognition and interpretation of sensory information mainly on memory

Perception: The nerve processes of recognition and interpretation

Perception: The insight, intuition, or knowledge gained by perceiving

Perception: The capacity for such insight

Watch the video below.

As humans we encounter many things each day as our senses are constantly processing data. For example, the bottom of our feet can simultaneously distinguish contact with a sock, the inside of the shoe, the surface on which one is standing or moving.

Our senses allow us to experience the world around us. Take a moment to think of all the things you perceive on a daily basis.

Perception is about our sensory experience of the world around us and involves both the recognition of environmental stimuli and actions in response to these stimuli.

Perceptions include the organization, identification and interpretation of sensory information in order to represent and understand the environment.

What the short video below.

All perception involves signals in the nervous system, which in turn result from physical stimulation of the sense organs.

Perception depends on complex functions of the nervous system, but subjectively seems mostly effortless because this processing happens outside conscious awareness.

Perception is influenced by past experiences, the situation, the expectation, and the intensity of the perception.

Watch the last video for the final test.
