The relation between Remember/Know/New (RKN) & Same/Similar/New(SSN) The purpose of using the SSN paradigm is to assess the level of detail in participant’s memory, whereas the purpose of using the RKN paradigm is to assess the level of subjective awareness in the participant’s memory. Even though the two paradigms have different criteria for giving a particular response they have a similar structure of a three level discrimination task which warrants a comparison between the two methodologies. This may provide further insight into the way in which participants interpret the task instructions in each case. A theoretical relationship between SSN and RKN responses was proposed by examining the criteria by which participants should respond if they are following the instructions for the tasks (See Table 3.5). This relationship was considered only for items that would be the same at study and test as these would be targets for some form of recognition in both tasks. In contrast a similar item would be given a response indicating some form of recognition in the SSN task, whereas the appropriate response in the RKN task should indicate no recognition memory because the item has not been seen before. New items would form the entire set of distractors for the SSN task but only a subset of distractors for the RKN task. 105
Table 3.5. Criteria for giving responses to same items in the Same, Similar, New task and Remember, Know, New task Same, Similar, New task Remember, Know, New task Same: Exact item seen before, recognition of specific visual details Similar: Recognise that an item similar to this, but not this exact photograph, was seen before OR Recognise item but cannot remember specific visual details so cannot give a ‘same’ response Remember: Recognition accompanied by some recollective experience of encoding context Know: Recognition accompanied by strong feelings of familiarity in absence of any recollective experience New: Do not recognise item New: Do not recognise item The criteria for giving a Same, Similar or New response should be based on an objective criterion of firstly whether there is any recognition of the item, and if there is whether there is recognition of specific visual details (same response) or not (similar response). The criteria for giving a Remember, Know or New response should also firstly be based on an objective criterion of whether there is any recognition of the items, and then considering whether any feelings of recollective experience accompany the recognition (Remember response) or not (Know response). Based on the criteria for giving these responses we proposed a relationship to describe how SSN and RKN responses may be related to each other (see Figure 3.3). 106
