Absolute identification is relative: A reply to Brown, Marley, and Lacouture (2007).
Stewart, Neil
Psychological Review, Vol 114(2), Apr 2007, 533-538.
N. Stewart, G. D. A. Brown, and N. Chater (see record 2005-13637-007) presented a relative judgment model (RJM) of absolute identification, in which the current stimulus is judged relative to the preceding stimulus. S. Brown, A. A. J. Marley, and Y. Lacouture (see record 2007-05396-014) found that the RJM does not predict their finding of increased accuracy after large stimulus jumps, except at the expense of other effects. In fact, the RJM does predict both the core effects and increased accuracy after large jumps (although it underestimates this effect) when better constrained parameters are estimated from the trial-by-trial raw data rather than from summary plots. Further, a modified RJM, in which the stimulus from two trials ago is sometimes used as a referent, provides a better fit. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
