Help validate brief interactive tests of attention and memory

I did this HIT a few days ago for $4.00 now it's $5.00 . You have to do some brain tests and it takes about 30 minutes. They pay quickly!

Requester ID A1HO20ABYX94W9, BTW, and there is a qualification that you have to request.

 

The $5 hit seems to be a follow up study of the $4 hit. This one is longer then the first one according to the directions.

"THIS IS A FOLLOW UP STUDY."

 

Yeah, I totally missed that the first time I read it..despite it being right at the top.
