1) the data type needs to be taken into account first. Is the score taken in the form of continuous data or just Yes - No? This is important. The importance of scoring is important
If you have continuous data you can use both but more Pearson is used
2.) It is also important that the data show normal distribution
If Pearson shows normal distribution, Spearman suggests if it does not show normal distribution ...
3) Your sample group if you are below 30 people, you can also do Spearman
I decide by taking these three criteria into account..you are looking for a nice and pleasant work topic :-))
