Chronostasis

Observe the duration of each tick of the clock. Many people perceive the duration of the tic that occurs when the clock changes color is longer than the others. It is not!

Timing in Speech Perception

Click the box above to hear the sound. The only difference between the first and second sound is in the interval between the first (fricative) and second (vowel) components. The first phoneme sounds like "si", the second like "sti".

Morse Code

Morse code essentially transforms language into a purely temporal code. Press the left box to hear the traditional "SOS" composed of three short - three long - three short. The "SOS" is played at 15 words per minute (wpm). Morse code experts can understand very complex patterns played very quickly, like the sound on the right ("Population Code" at 40 wpm).
