The encoding specificity principle indicates that memory performance is affected by the degree of overlap between the learning context and the test context. Retrieval is facilitated when test conditions match encoding conditions, and this is called “context cuing effect”. The context cuing effect in item recognition was found quite unstable. Some researches proposed that only the ‘‘ensemble information'’ meaningfully integrated and bind uniquely with the item information could be an effective context cue. But so far, most studies in this area focus on the context cuing effect on item memory, few researches were conducted on the context cuing effect on source memory. The present study was conducted to examine in what kind of conditions the context cuing effect does appear when there were multidimensional source memories. In detail, whether the associativity of multidimensional source memories could generate context cuing effect in the retrieval of source memory and whether cue load would affect that course were investigated. Two experiments were conducted. Neuter words composed of two Chinese characters were used as items and background colors were used as context cue. In experiment 1, background locations were used as another dimension of source memory. Twelve college students took part in the experiment executed on a P4 computer. The experiment adopted a 3×3 with-in subject design. Three cue validity conditions (match, mismatch, new) and three cue load conditions (1:1, 1:2, 1:3) were arranged. In the stage of study, a word with a colored background rectangle was present on one location of a watch plate. Participants were instructed to remember the word, the color and the location. And then participants did a task to distract their attention for 90s. In the stage of test, a word with a colored background rectangle was present in the middle of the screen, and participants were asked to judge whether the word was old or new. If they judged that the word was old, then they were asked to point the location where the word was present in the stage of study with mouse. Accuracy rate of response of the location of the old word was recorded. The procedure of experiment 2 was the same as experiment 1 except the dimension of source memory which was background shape. The results indicated that (1) main effect of cue validity condition was not significant in experiment 1 which means background color could not become the context cue to the location source; (2) main effect of cue validity condition and cue load were all significant in experiment 2 which means background color could be used as an effective cue to the background shape; (3) context cue effect decreased as the increase of cue load in experiment 2. The results show that context cue effect could be generated by the associativity of source memories in the retrieval of source memory, which means remembering information of one source dimension will facilitate recalling information of another source dimension when the associativity of the two source dimension is high. Low cue load could promote the emergence of context cue.
