Two experiments used a methodology in which elements in a serially presented sequence of 5 elements were randomly reinforced during training. To assess what was learned, elements were systematically swapped with each other during testing. The usual outcome measures in implicit sequence learning of this type are either a random test in which elements are disarrayed, or pairwise tests in which subjects choose between two elements. Each of these methods possesses shortcomings. The random test is a blunt measure, whereas pairwise tests disrupt the usual flow of elements in a serial sequence. Pairwise tests also present the problem of how to reinforce subjects during testing in a way that doesn't violate the delivery of reinforcement on a random basis. The swaps methodology is more targeted in that only two elements exchange ordinal positions. The procedure is at once more precise than the standard random test and is less disruptive to the flow of an implicit sequence than are pairwise tests. Results of both experiments indicated that the swaps manipulation was successful in disrupting latencies. Regression analyses indicated that subjects learned something about the ordinal position of elements. The separate analysis of symbolic distance versus spatial distance in Experiment 2 provided evidence, but only provisional evidence, of a symbolic distance effect in implicit learning.

This chapter examines Roman ambivalence towards Greek culture in testimonies of Cato the Elder, L. Crassus, and M. Antonius. It investigates why these orators expressed feelings of ambivalence despite their thorough education in Greek paideia. This chapter argues that a key aspect for understanding Roman ambivalence is the inherent conflict between the hierarchical structure of Roman society, granting supremacy to the speaker with the highest auctoritas in public debate, and the more egalitarian Greek notion of the primacy of the most compelling argument. The Romans’ disposition to strongly distinguish themselves from other cultures is illustrated by the consistent use of Latin when Romans dealt with Greeks in official contexts and the exclusivity of Roman citizenship. It is suggested that this disposition may also have contributed to Roman ambivalence towards Greek learning in the second and early first centuries BC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
