Intertrial responses in defensive instrumental learning.
Data by the author, as well as from other laboratories, show residual fear as the main source of intertrial responses (ITR) during defensive instrumental training in rats, cats and dogs. Between-subject differences in ITR rate arise in the course of training. The differences depend on training conditions and on subject's emotionality. Under the same conditions higher ITR rates correspond to mor...
متن کامل\ / Instrumental Conditioning
I Instrumental behavior refers to those actions whose acquisition and mainte nance depend on their consequences for the animal or, in others words, on the fact that the action is irzslrumClllal in causing some outcome. The func ,t tional significance of the capacity for instrumental action is gO obvious.as to require little comment; it is this capacity that allows us and other animals to lear...
متن کاملVariation of the intertrial interval in human classical conditioning
152 The eyeblink conditioning paradigm has been widely used as a model system to study associative learning (Disterhoft, Kwan, & Lo, 1977; R. F. Thompson et al., 1976). The neurobiological substrates underlying learning in this task have been extensively studied in animals (Disterhoft, L. T. Thompson, & Moyer, 1994; Moyer, Deyo, & Disterhoft, 1990; R. F. Thompson, 1991) and humans (Daum, Channo...
متن کاملInterneuronal cortical connections and intertrial responses in appetitive instrumental learning.
The organization of interneuronal cortical connections in intertrial periods was studied in 4 cats trained to perform the delayed appetitive instrumental response to a visual conditioned stimulus (CS). Crosscorrelationl analysis revealed changes in intra- and intercortical neuronal networks of the visual and motor cortical projection areas. Depending on the form of behavior in the intertrial pe...
متن کاملSpatial Memory and Instrumental Conditioning
Short-term spatial memory of rats was studied in a 12-arm radial tubular maze. Correct performance does not depend on maze structure which affects, however, thse rat's trajectory through the maze. Rats overtrained in the 12-arm radial maze show considerable transfer of the habit to a maze consisting of 12 parallel alleys entered froin a common choice area. When isolated maze channels equipped w...
