Serial-probe-recognition (SPR) performance by 2 monkeys deteriorated over several months of training. Three hundred and twenty different items were presented without repetition within a session (trial unique) but were repeated between sessions. The cause of the deterioration was identified as proactive interference (PI) due to repetitive use of items from day to day. Introduction of novel stimuli across days improved performance from 63% to 82% correct (Experiment 1). Tests with only probe items and no list items (Experiment 2) revealed that the monkeys were using a familiar/novel response strategy in combination with a relational strategy (relating the probe item to the list items) to further improve their SPR performance. Intermixing familiar baseline trials and novel transfer trials within a session (Experiment 3) encouraged the subjects to use a relational strategy, and it improved performance on baseline trials as well as on transfer trials. Possible qualitative similarity between the relational strategy and the familiar/novel response strategy is discussed along with theoretical implications of these findings for experiments which have used small number of repeating stimuli within a session.
两只猴子的连续探针识别（SPR）表现经过数月训练后变差。在一个实验环节中，320个不同的物品无重复呈现（每次实验唯一），但在不同实验环节中会重复。变差的原因被确定为由于日复一日重复使用物品导致的前摄干扰（PI）。每天引入新刺激将正确率从63%提高到了82%（实验1）。仅使用探针物品而无列表物品的测试（实验2）表明，猴子们结合使用熟悉/新颖反应策略和关联策略（将探针物品与列表物品关联）来进一步提高它们的SPR表现。在一个实验环节中混合熟悉的基线实验和新颖的迁移实验（实验3）促使受试者使用关联策略，这提高了基线实验以及迁移实验的表现。文中讨论了关联策略与熟悉/新颖反应策略之间可能存在的定性相似性，以及这些发现对在一个实验环节中使用少量重复刺激的实验的理论意义。
