Concentration
we will measure concentration using the score of the

OPERATIONAL DEFINITION
Memory Span
A list of random numbers or letters will be presented on a computer screen at the rate of one per second. The test begins with two to three numbers, increasing until the person commits errors. The score of this test will serve as an indication of memory span.
OPERATIONAL DEFINITION
Music
This will be our independent variable on which other variable will depend. This can take three values no music, music with lyrics and music without lyrics.

hypothesis
- Music has a negative impact on cognitive performance
- Music with lyrics affects cognitive performance more than music without lyrics
methodology
- Selected a random group of people
- Short survey for subjects about their demographic background
- Selected a randomisation method; to give subjects three cards to put in a random order (each card was labelled either music with lyrics, music without lyrics or no music) to randomly decide the order they will take the tests in.
- Asked subjects to play Stroop test and memory span game three times: once with music with lyrics; once with a music without lyrics; and once with no music at all.
Result prediction
Cognitive Performance order
No Music > Music without lyrics > Music with lyrics
conclusion
- Whenever we listen a sound our brain will try process so the participants should exhibit better cognitive performance in case of no music
- When we listen to music with human voice, our brain tries to interpret it hence a decrease in cognitive performance
