I was wondering if anyone could speak to the differences between Psychopy and DirectRT. For my research project, participants see a series of pictures that flash across the screen. Every participant sees 2 pictures and on the second picture, they must judge whether it is nice looking or not nice looking by clicking a button. Once the button is clicked, the next two pictures should flash, and then they judge again and so on and so forth. I am wondering which platform is best/more user friendly/ does Psychopy do anything that DirectRT does not?
