In Experim.nt.1, st.m.lus pairs included a choice bet.een a clot. wit. a reward on t.e upper right.com.r or wit. a second reward off t.e clot., adjacent.t. a com.r, wit. t.e second pair com.rised of a clot. wit. food on t.e upper right.com.r, and a second clot. wit. t.e reward on t.e subst.at., part.ally covered.
