In Exp 1, 3 college students (aged 21-23 yrs) were exposed to relational pretraining to establish the contextual functions of Same, Opposite, More Than, and Less. Response latencies to probes for derived Same/Opposite relations were significantly lower than those for derived More Than/Less Than relations. Exp 2 exposed 4 Ss (aged 18-21 yrs) to training across each of the 4 relations and used a novel stimulus set to test for reduced response latencies to the derived relations. Response latencies to More-Than/Less-Than probes reduced significantly across the original to the novel stimulus set, whereas latencies to Same/Opposite probes were low across both stimulus sets.

The authors measured response latencies to mutually entailed same, opposite, more-than, and less-than relations. Response latencies to same and opposite relations were significantly faster than more-than and less-than relations. A second experiment showed a gradual decrease in response latency for more/less relations across a novel stimulus set.
