“…However, the intradimensional dependencies related two vowels, whereas the interdimensional dependencies related a vowel and a consonant. Experiments with non-phonological stimuli, and even with non-human subjects, have repeatedly shown that perceptual similarity facilitates association between the elements of a compound stimulus (Köhler, 1941;Prentice and Asch, 1958;Arnold and Bower, 1972;Rescorla and Gillan, 1980;Rescorla, 1986;Creel et al, 2004;Rescorla, 2008). To test whether this effect is sufficient to explain the results of Experiments 1 and 3, Experiment 4 compared two interdimensional patterns, one relating vowels and the other relating a vowel and a consonant.…”
