Asymmetrical cross-language priming effects

Three experiments were conducted to examine cross-language priming in bilinguals. The first was a cross-language primed lexical decision task experiment with Chinese-English bilinguals. Subjects made lexical decisions about primary associate targets in the two languages at the same rate, but priming occurred only when the prime was in their first language (L1), Chinese and the target was in their second language (L2), English. Experiment 2 produced the same pattern of asymmetrical priming with two alphabetic languages, French and Dutch. In Experiment 3, the crucial stimuli were translation equivalents. In contrast to the results of Experiments 1 and 2, priming occurred across languages in both the L1-L2 and L2-L1 conditions. However, this priming was also asymmetrical, with more priming occurring in the L1-L2 condition. A tentative separate-interconnected model of bilingual memory is described. It suggests that the representations of words expressed in different languages are stored in separate memory systems, which may be interconnected via one-to-one links between some translation equivalent representations as well as meaning-integration processes.link_to_subscribed_fulltex

The role of the orienting response in the anticipation of information: A skin conductance response study

Theoretical positions concerning the role of the orienting response (OR) in information-processing and attention have viewed the OR either as indexing an active increase in information-processing efficiency, or as passively reflecting the results of information processing. This paper reports a skin conductance response (SCR) study of a two-stimulus anticipation experiment, where a warning stimulus (WS) informed subjects of the nature of an impending imperative stimulus (IS). The subjects' task was to identify as much of the IS as possible. Both the WS and the IS varied in information content and stimulus duration. SCR magnitude in the WS-IS interval varied according to the anticipated information processing requirements and was more sensitive to IS variation than WS variation. It is concluded that these responses index an anticipatory, activating process closely related to that suggested of the OR by Sokolov (1966), and consonant with the functional characteristics of the autonomic nervous system. Registration of information appears to be neither a necessary determinant of OR magnitude, nor a parsimoniously useful part of OR theory.link_to_subscribed_fulltex
