The effect of varied reinforcement on acquisition and extinction speed.
BACKGROUND The objective of the present study was to compare both the acquisition speed and the resistance to extinction of a simple discrimination in pigeons, depending on whether the reinforcing consequence included different conditioned reinforcer stimuli or always the same. METHOD The study was conducted with four experimentally naive female pigeons, which were trained to respond to a &ld...
متن کاملA partial reinforcement extinction effect despite equal rates of reinforcement during Pavlovian conditioning.
In 4 experiments rats received appetitive Pavlovian conditioning followed by extinction. Food accompanied every trial with the conditioned stimulus (CS) for the continuously reinforced groups and only half of the trials for the partially reinforced groups. In contrast to previous experiments that have compared the effects of partial and continuous reinforcement, the rate at which food was deliv...
متن کاملTemporally massed CS presentations generate more fear extinction than spaced presentations.
Rodent fear conditioning models both excitatory learning and the pathogenesis of human anxiety, whereas extinction of conditional fear is a paradigm of inhibitory learning and the explicit model for behavior therapy. Many studies support a general learning rule for acquisition: Temporally spaced training is more effective than massed training. The authors asked whether this rule applies to exti...
متن کاملReinforcement learning over time: spaced versus massed training establishes stronger value associations
Over the past few decades, neuroscience research has illuminated the neural mechanisms supporting learning from reward feedback, demonstrating a critical role for the striatum and midbrain dopamine system. Learning paradigms are increasingly being extended to understand learning dysfunctions in mood and psychiatric disorders as well as addiction in the area of computational psychiatry. However,...
متن کاملPartial reinforcement of avoidance and resistance to extinction in humans.
In anxiety, maladaptive avoidance behavior provides for near-perfect controllability of potential threat. There has been little laboratory-based treatment research conducted on controllability as a contributing factor in the transition from adaptive to maladaptive avoidance. Here, we investigated for the first time whether partial reinforcement rate, or the reliability of avoidance at controlli...
