Abstract
Tests were applied for incremental and all-or-none learning in a situation where each of 2 responses was equally reinforced with a stimulus complex consisting of 2 3-letter nonsense syllables. Learning was continued for 7 trials, and cases where subjects could give both correct responses were analysed to see whether they occurred with separate nonsense syllables or with the same one. It was found that when two responses were attached to a stimulus complex, both responses were elicited by each of the component stimuli. This result would not normally be predicted from an S-R conception of learning, but is favourable to derivations from the expectancy theory of MacCorquodale & Meehl.
