| Abstract: Rule governed behavior, such as forming stimulus equivalence classes using graphic stimuli depicting rhyming objects, is often said to facilitate or underlie the establishment of stimulus equivalence (Randell & Remington, 1999); however, it is possible that rule-governed behavior is actually mimicking contiguity derived equivalence (Rehfeldt & Hayes, 1998). Undergraduate students memorised patterns comprised of three coloured shapes. Experimental participants then completed stimulus equivalence tasks using two of the coloured shapes from a pattern joined by a novel coloured shape. One group were prompted to use rule based memorial strategies, a second group were given no instruction on strategies. A control group completed a vigilance task using the same stimuli. A final recognition test presented the original patterns as well as lures, or false patterns, comprised of the stimulus equivalence task stimuli. Participants in the control group were not misled by the lures. A significant majority (over 60%) of participants who completed the stimulus equivalence task with no advice as to strategy incorrectly identified lures as original patterns. In contrast, participants in the rule-prompted group were only half as likely to be misled. Data collection is ongoing. Potential differences between rule-governed and contiguity derived stimulus equivalence are discussed. |
