Motor Theory of Perception - In 100 words or less

Many of us tap our feet when listening to music. Some of us even wave our hands in a particular manner, representing the dynamics of the song.


But why do we do these mostly involuntary actions?


The Motor Theory of Perception says that music and body movements are deeply rooted in our cognition; we simulate the motion associated with the sensory stimuli we process, to comprehend it.


So, while listening to music, we try to reproduce the sounds that have gone into producing it.


We create these mental images in an attempt to be au fait with the music.

Triangular Arbitrage - In 100 words or less

Triangular Arbitrage is a situation that arises when exchange rates do not  exactly  match up -  Exchange Rate Discrepancies . Say you had  k1  units of currency A.   When converted to currency B,  k1  becomes  k2. When converted to currency C,  k2  becomes  k3. Ordinarily ,  when we convert  k3  to currency A, we get  k1  back.  But, in this condition, we would get more than  k1 ! As cool as this sounds, for an average person, it is hopelessly impractical because these are few and far between.

Nostalgia - In 100 words or less

Nostalgia is a powerful emotion that is invoked by anything that resembles our past experiences . Sensory stimuli are popular triggers, and at times, nostalgia is elicited on purpose to feel better about current events.  The hippocampus, substantia nigra, ventral tegmental area, and ventral striatum -  Reward Centers of the brain  - are activated during nostalgic activity.  So, when listening to say, an old song, you might feel happy even if that song wasn't to your liking then - you reminisce about past times.  Nostalgia is so comforting and so easily provoked, that it can even become an addiction.

Polyphasic Sleep - In 100 words or less

Most of us sleep in a  single six to nine-hour stretch - monophasic sleep .    Polyphasic Sleep seems to be a viable alternative to some athletes and productivity freaks, which mostly consists of one long sleep of a few hours and several shorter sleep periods . Babies and pets commonly practice this form of sleep.   While polyphasic sleep might work for certain specific situations or groups of people by making sleep deeper and hence more productive, it is generally not advisable for students or employees. This is because its improper practice can lead to sleep deprivation, irritability, and general fatigue .
