People say: English has no grammar!
I wonder why so many learners find the present perfect extremely difficult. I am interested in finding better ways to explain the present perfect.
In this experiment the participant can
a) test his knowledge of the present perfect, or
b) learn a few interesting details about the present perfect.
Experiment created on a workshop by U. Reips on Internet-based experimenting
We are interested in shared beliefs about racial category membership. We are asking you to help us by viewing a number of pictures and telling us which race you think the person in the photo might belong to. Some of your identifications may be more difficult than others, so we are asking you to tell us how confident you are for each judgment. In exchange for your participation, we will tell you about some of our more interesting hypotheses, and you will have the option to learn more about our research as it progresses.
