    "abstract": "The evidence concerning the level at which learned CP\neffects occur is complex. The goal of this study was to use\na different approach to this question by manipulating the\nabstractness of the information available for distinguishing\npairs of items in an XAB task, and the presence or absence\nof a short task-filled delay between X and AB. Participants\nengaged in XAB trials containing a mixture of trials with\nand without the delay task before and after standard training\nto classify visual texture stimuli into two categories.\nTraining improved discrimination of pairs differing on the\ncategory-relevant dimension whether within- or betweencategory,\nbut not on pairs differing only on non-category\nrelevant low level features. In addition, only successful\nlearners in the post-training trials avoided decreased\ndiscrimination accuracy due to the delay task, suggesting\nthat they formed more stable representations. However, this\neffect was not limited to pairs varying in category-relevant\nways.",
