In lines with my previous blog post regarding emotional research and design, at times you may want to control the lab setting to elicit certain brainwaves and emotions within the participants prior to lab testing.

In the field of Psychology, Neuroscience, etc there are plenty of experimental research design that bess for manipulating emotions before and/or after task tests.
Anyone interested, there are many easy ways to do this. I highly recommend reading about Lang’s IAPS techniques, to start.
Needless to say that consent forms and research ethics regulations ought to be honored prior to running such experimental designs.
