The brain seems to be able to recognize things regardless of how are they are presented, because the brain primarily recognizes relationships between features. Computers basically recognize things based on absolute patterns; a pixel pattern that a computer can recognize as a dog will no longer be recognized if the image is shifted 5 pixels to the left, because the computer gives precedence to the locations of the pixels. The human brain, on the other hand, seems to give precedence to the relationships between the features, so on a face of a dog, the human will recognize the face because of the distance between the eyes and the ears, the length of the ears, etc. Such general recognition based on features is sometimes (although rarely) referred to as the brain representing information in **invariant forms**. A great example of this phenomenon can be seen in music, where a melody will be recognized only on the basis of the relative pitches from a starting note. We will not be perturbed if a melody starts on A, F, or G, for instance, but we will notice that the melody is wrong if a note interval is incorrect when the melody is being played. --- #Psychology/Cognition #Philosophy/Mind *June 10, 2021* #2021/6
