Description
Source monitoring refers to the ability to discriminate the origins of memories. The source monitoring framework is a theoretical model that describes the various characteristics of memories and judgement processes necessary for this discrimination process. Little research has analyzed the extent to which predictable encoding contexts influence source monitoring processes. In this study, we found that predictability at encoding aids later source recognition, but only when the test-relevant source dimension was predictable at encoding. The encoding format was either predictable (sequential spatial location) or non-predictable (random spatial location) and the test format was either color or location. In Experiment 1, the encoding format was either predictable or non-predictable spatial locations and participants were tested on the location. In this experiment, predictability did aid when the encoding format matched the test format. The average conditionalized source identification measure was statistically higher for those who saw images appear in a predictable pattern at encoding. In Experiment 2, when participants were tested on an orthogonal source dimension, the average conditionalized source identification measure was not statistically significant for those who saw the images appear in either encoding format. In this experiment, the predictability did not have an effect when the encoding format did not match the test format. In Experiment 3, there was a significant interaction of predictability by source dimension showing an improvement to memory for the predictable source condition and a decrement to memory for the unpredictable source dimension. In this experiment, predictability aided when encoding format matched the test format, but not when the encoding and test format did not match.
