Prior experience can influence whether the whole is different from the sum of its parts

Abstract In two conditioning experiments with humans, we found that participants’ prior experience exerted considerable influence on later learning of configural discrimination problems. Prior experience was manipulated by pre-training participants before the main acquisition stage. They either received a discrimination problem that encouraged an elemental solution (A+, B−, AB+, CD− in Experiment 1 and A+, AB+, C−, CB− in Experiment 2) or one that required a configural solution (AB+, BC−, CD+, DA− in Experiment 1 and A−, AB+, C+, CB− in Experiment 2). Then, all participants were shown a discrimination that required a configural solution (E+, F+, EF− in Experiment 1 and DE+, EF−, FG+, GD− in Experiment 2). In both experiments, participants who had received elemental pre-training were impaired on the later configural problem compared to participants who had received configural pre-training. The results suggest that organisms can flexibly process stimuli elementally or configurally.
