Acquisition in Autoshaping
Quantitative data on the speed with which animals acquire behavioral responses during classical conditioning experiments should provide strong constraints on models of learning. However, most models have simply ignored these data; the few that have attempted to address them have failed by at least an order of magnitude. We discuss key data on the speed of acquisition, and show how to account fo...
متن کاملAcquisition and extinction in autoshaping.
C. R. Gallistel and J. Gibbon (2000) presented quantitative data on the speed with which animals acquire behavioral responses during autoshaping, together with a statistical model of learning intended to account for them. Although this model captures the form of the dependencies among critical variables, its detailed predictions are substantially at variance with the data. In the present articl...
متن کاملThe source of keypecking in autoshaping
Pigeons were trained to step on a treadle to operate a grain hopper, under the control of an auditory stimulus. Subsequently, autoshaping consisted of pairing illumination of a response key with some of the subsequent tone presentations, reinforcement occurring only after a treadle response. One control group did not have a treadle or a treadle-response requirement. A second control group recei...
متن کاملAutoshaping and automaintenance: a neural-network approach.
This article presents an interpretation of autoshaping, and positive and negative automaintenance, based on a neural-network model. The model makes no distinction between operant and respondent learning mechanisms, and takes into account knowledge of hippocampal and dopaminergic systems. Four simulations were run, each one using an A-B-A design and four instances of feedfoward architectures. In...
متن کاملTemporal specificity of extinction in autoshaping.
Three experiments investigated the effects of varying the conditioned stimulus (CS) duration between training and extinction. Ring doves (Streptopelia risoria) were autoshaped on a fixed CS-unconditioned stimulus (US) interval and extinguished with CS presentations that were longer, shorter, or the same as the training duration. During a subsequent test session, the training CS duration was rei...
