The research used the isolation model, which refers to a unique feature of an item in a list that differs from the others by way of dimension. Such distinctiveness, pointing to the von Restorff effect, can be formed from turning the meaningfulness or physical nature of the incentive in some way, such as in size, shape, color, spacing and underlining.

Hedwig von Restorff

Hedwig von Restorff used the isolation model in the experiments involved in her 1933 paper. Her use of the isolation model was to further study interference effects. Despite critique towards the use of nonsense syllables beginning in the psychological community at this time, von Restorff dedicated the first page of her published paper to defending her choice in the usage of them. Afresh her study, von Restorff performed her participants by three lists of items over a span of three days. On an opening day, the things on the list were all unrelated and consisted of five various types of materials, ending with eight pairs total. Half of the sets consisted of fun syllables, while the other half represented the other four types of materials (numbers, words, letters, symbols). On the next two days, participants were given lists that contained an isolated item among homogeneous items. The separate item befell in either the second or third position on the list. Members were given particular memory instructions and examined on their recall of the things they were shown.
