Тезаурус:

1. Should acquired equivalence, then, be interpreted as concept formation rather than perceptual learning?
2. The mechanism supposed by Miller (1948) to underlie acquired equivalence is that introduced by Hull (1939) with his notion of secondary generalization.
3. It would also be open to the theorist, of course, to devise a mechanism for acquired distinctiveness and to attribute the whole of the effect to this, denying the reality of acquired equivalence.
4. We need now, therefore, to consider the empirical work that has been done on the topic of acquired distinction (and on acquired non-distinctiveness or equivalence).
5. The evidence discussed in this final section of the chapter has been uniformly in favour of the associative account of acquired equivalence and distinctiveness.
6. Mediation theory requires that X and Y be rather different from each other if the formation of A-X and B-Y associations is to lead to an increase in the discriminability of A and B. 1f X and Y are made more similar, the effect will be reduced (the limiting case, when X and Y are identical, being that in which acquired equivalence is held to occur).
7. There is generally a size bias in all predator assemblages and a predictable size equivalence between predator and prey.
8. And attempts to demonstrate empirically the operation of an acquired equivalence mechanism distinct from that responsible for acquired distinctiveness have proved unsuccessful.
9. Following Lea (1984), they suggest that true conceptual categories involve equivalence classes of stimuli that are not tied together by perceptual similarity, Mediated generalization is clearly not to be regarded, according to this view, as making the stimuli perceptually more similar.
10. Whatever the theoretical possibilities, it is clearly more parsimonious to explain acquired distinctiveness and equivalence solely in terms of associative mechanisms.
11. It is worth adding, as something of an aside, that the experimental result just described not only gives reasons for preferring the associative account but also seems to demand an explanation in terms of acquired equivalence rather than acquired distinctiveness.
12. Indeed, to the extent that X is perceived as being similar to Y (i.e. to the extent that these events hold elements in common), the acquired equivalence mechanism will operate, with these common elements (the z elements) mediating generalization from A to B.
13. We can say, however, that whatever may be true of acquired distinctiveness, the reality of acquired equivalence must be accepted.
