Abstract:
A verbal discrimination (VD) study phase was followed by a single-item (i.e., one item at a time) test phase. Prior right (R) items from the VD list were found to have higher old-new hit rates on the test phase than prior wrong (W) items. However, prior W items had higher hit rates than prior R items in terms of recognition of their intrapair function. These results were interpreted in terms of a high criterion model whereby an old test item must prossess a large number of frequency units before it is identified as being R. In addition, false recognition effects were demonstrated for new test items that were homophones of prior R items, but not for new test items that were homophones of prior W items. These results were interpreted in terms of a feature analytic extension of frequency theory.
