WK 2 Edit
The measure you chose does not measure what you think it does. It measures music receptivity. In other words, it will not tell you whether the individual feels happy or sad when listening to the musics. It refers to whether the person internalizes the music at the point of listening to it. I read the article. This is not what you think it is.
For the Measures section, you are supposed to explain the measure. How many items? How are the questions answered? Likert Scale? Scale? True or false? What does it measure and is it reliable and valid.
Also, you do not need smiley face or word cards. You also do not want to deal with children. Your sample needs to be much higher 200. Also, pick a population. You are assuming older people don’t care about?
