When you hear a song on the radio that was a favorite tune during your teen years, or perhaps early 20's, does your heart flutter at the memory of your life back then? Did you play that song over and over again on your phonograph? Or, were you falling in love at the time a tune was most popular? As a teen or young adult, storing the memory of songs which spark our attention when hearing it on the radio is known as the ‘reminiscent bump’. Besides music, this psychological analysis for our response to certain songs also holds true for books and movies. At the age of 10 until 25, our minds absorbed the repetitive sounds of our favorite tunes, and what was going on in our lives at the time. The age from 16 until 20 is the peak period of this ‘reminiscent bump’ period. So, the next time you hear an oldie, but goodie, there is a reason behind your nostalgic emotions. Enjoy the memories!
