The Higher Education Academy (HEA) provided a partial buyout of teaching for Jonathan Peirce at the University of Nottingham to write these lectures 2010-11. We subsequently decided that it would be worth having one year where the undergraduates learnt about both E-Prime and PsychoPy, for evaluation purposes. As a result, for 2010-11 only the practicals 1-6 have so far been used in the classroom with the other classes that year using E-Prime instead. The later lectures, on Memory and Inhibition of Return are therefore less well developed and should be carefully road-tested by you!
