Effects of inescapable shock upon subsequent escape and avoidance responding.
Exposure of dogs to inescapable shocks under a variety of conditions reliably interfered with subsequent instrumental escape-avoidance responding in a new situation. Use of a higher level of shock during instrumental avoidance training did not attenuate interference; this was taken as evidence against an explanation based upon adaptation to shock. Ss curarized during their exposure to inescapab...
متن کاملAnterograde effects of a single electroconvulsive shock on inhibitory avoidance and on cued fear conditioning.
A single electroconvulsive shock (ECS) or a sham ECS was administered to male 3-4-month-old Wistar rats 1, 2, and 4 h before training in an inhibitory avoidance test and in cued classical fear conditioning (measured by means of freezing time in a new environment). ECS impaired inhibitory avoidance at all times and, at 1 or 2 h before training, reduced freezing time before and after re-presentat...
متن کاملCentral mediation of hormonal influences on instrumental avoidance conditioning.
Two behaviorally active hormones of the pituitary-adrenal system are adrenocorticotropic hormones (ACTH) and corticosterone, and their behavioral effects are facilitation and inhibition of performance of previously learned avoidance responses, respectively. Their uptake, distribution and effects on central nervous system are reviewed. Hypothalamic neurotransmitter control of corticotropin relea...
متن کاملQuantitative two-process analysis of avoidance conditioning in goldfish.
The shuttlebox performance of goldfish was studied under standardized conditions in a variety of problems--with or without an avoidance contingency, a conditioned stimulus (CS)-termination contingency, and an escape contingency. The effects of CS-only, unconditioned stimulus (US)-only, and explicitly unpaired training were also examined. All the data could be simulated quantitatively with a ver...
متن کاملObstacle Avoidance by Means of an Operant Conditioning Model
This paper describes the Clpplication of a model of operant conditioning to the prohlcrn of obstacle avoidance \Vith a wheeled mobile robot. The main characteristic of the 8pplicd model is that the robot learns to avoid obstacles through a learning-by-doing cycle without external supervision. A series of ultrasonic sensors aetas Conditioned Stimuli (CS), while collisions act as an Unconditioned...
