Component summation or configuration in human eyelid conditioning depends upon stimulus properties.
The experiment reviewed here merges Garner's (1974) distinction of separable and integral stimulus properties with the field of Pavlovian eyelid conditioning with human subjects. According to one rule, two sets of stimuli (separable vs integral) were constructed. A differential compound conditioning procedure was used with one group of subjects being trained with a subset of the separable material and then tested with a new subset. The same procedure was used with a second group but with integral material. The experiment showed a reversal of conditioning effects, depending on the properties of stimuli. Separable compounds showed results as predicted by elementistic conditioning theories: the associative values of the elements summed up. With integral compounds, the associative values of the elements were irrelevant. Instead, integral compounds were processed and classified primarily on the basis of similarity.
