The purpose of this experiment was to examine by means of an PI release paradigm whether the buildup of proactive interference (PI) was attribute to failure to generate discriminated items by using retrieval cue or difficulty to discriminate between present trial items and previous trial items in retrieval phase. A 3×4 factorial design was used, which incorporated retrieval cue conditions (discriminative cue, item cue, control) and number of trials (from 1 to 4). The subjects were 54 students with a mean age of 20 years and 4 months and were given to three Brown-Peterson trials and one release trial, each of which had three subcategorical items. A third of subjects were presented subcategory name as a discriminative cue during retrieval phase in release trial (discriminative cue condition) , another third were presented triads of immediate previous trial during retrieval phase in release trial (item cue condition) , and the last third were not presented any cue during retrieval phase in release trial (control condition). The main results were as follows(see Fig.1): on the performance of trial 1 to 3 under three conditions, PI were built up as a function of trials. The performance differences were found among three conditions on the 4th release trial. Under the discriminative cue condition, large PI release was produced by discriminative cue. Under the item cue condition, small PI release was produced by immediate previous items cue. PI release was not produced under the control condition,. These results suggest that the buildup of PI was interpreted in terms of failure to generate discriminated correct items by using retrieval cues rather than difficulty to discriminate between present trial and previous trial items.
