Which mechanism has not been proposed as an explanation for perceptual learning?
A) The common elements of two stimuli develop more latent inhibition than the unique elements, and thus less generalization and confusion occur between the two stimuli.
B) The common element will produce retrieval-generated priming of one of the unique elements that will not occur, and thus the unique elements will become inhibitory signals for each other.
C) Complex stimuli have such a large number of features that only a fraction are sampled at any one time. In pre-exposure, more and more features are linked to one another, thereby producing pattern completion when just a subset of features is presented.
D) The elements of the stimuli contribute to latent learning that is not manifest in behavior due to a lack of motivation. Perceptual learning is another case of the learning performance distinction: When no incentive is present, a behavior is less likely to occur.

Explanation: Options A, B, and C all describe mechanisms that involve specific interactions between elements of stimuli or features that contribute directly to perceptual learning through processes like latent inhibition, retrieval-generated priming, and pattern completion. Option D, however, describes latent learning in a general sense, focusing on the learning-performance distinction related to motivation rather than a mechanism specific to perceptual learning. This makes it the correct choice as the mechanism not proposed for perceptual learning, as it does not directly explain how perceptual learning occurs through interaction with or differentiation between stimuli features.
