Comparing data 2AFC-4AFC

Dear List=2C

       Can any one tell some possible ways of comparing the results of discrimination (4-Alternative Forced Choice ) and ranking (2-Alternative Forced Choice) ?

Hello –

With some reticence, I recommend Detection Theory, where a widely supported model of decision-making which allows comparison of data from different detection tasks.

Macmillan, N.A. & Creelman, C.D. Detection Theory: A users’ guide 2nd Ed. Erlbaum, 2005.

Check out Chapter 10 and Table 5.7
