The Mechanics of Associative Change
نویسنده
چکیده
Rescorla (in press) investigated the change in associative strength undergone by cues A and B as a result of reinforcement or nonreinforcement of an AB compound. Many leading theories of associative learning predict that if A and B are equally salient then the associative change experienced by each should be the same regardless of their associative strength preceding AB trials. Rescorla explored this prediction for a compound composed of an excitatory A and an inhibitory B, using rats and pigeons as subjects. We repeated Rescorla’s experiment using human subjects and a causal judgment task, and obtained diametrically opposite results to those of Rescorla’s earlier study. The implications of this finding are discussed with reference to a number of influential theories of associative learning.

The article is devoted to the study of language representations of the concept of “woman” in the minds of the Russian and Chinese people based on a comparison of associative experiments of two languages, identifying the dynamics of the concept in the language consciousness of the people, establishing the specificity of the concept in the Russian language picture of the world referring to the Ch...
متن کاملON STRONGLY ASSOCIATIVE HYPERRINGS
This paper generalizes the idea of strongly associative hyperoperation introduced in [7] to the class of hyperrings. We introduce and investigate hyperrings of type 1, type 2 and SDIS. Moreover, we study some examples of these hyperrings and give a new kind of hyperrings called totally hyperrings. Totally hyperrings give us a characterization of Krasner hyperrings. Also, we investigate these ...
متن کاملPreferred Lexical Access Route in Persian Learners of English: Associative, Semantic or Both
Background: Words in the Mental Lexicon (ML) construct semantic field through associative and/ or semantic connections, with a pervasive native speaker preference for the former. Non-native preferences, however, demand further inquiry. Previous studies have revealed inconsistent Lexical Access (LA) patterns due to the limitations in the methodology and response categorization. Objectives: To f...
متن کاملA non-associative quantum mechanics
A non-associative quantum mechanics is proposed in which the product of three and more operators can be non-associative one. The multiplication rules of the octonions define the multiplication rules of the corresponding operators with quantum corrections. The self-consistency of the operator algebra is proved for the product of three operators. Some properties of the non-associative quantum mec...
متن کاملA Self-Reconstructing Algorithm for Single and Multiple-Sensor Fault Isolation Based on Auto-Associative Neural Networks
Recently different approaches have been developed in the field of sensor fault diagnostics based on Auto-Associative Neural Network (AANN). In this paper we present a novel algorithm called Self reconstructing Auto-Associative Neural Network (S-AANN) which is able to detect and isolate single faulty sensor via reconstruction. We have also extended the algorithm to be applicable in multiple faul...
