Unformatted text preview: -Variable Ratio Schedule – the reinforcer is given after a variable number of non reinforced responses-Interval Schedules – require time to pass between presentations of reinforcer-Fixed Interval – after a fixed time interval has elapsed -Variable Interval – after a variable time period has passed. Positive Reinforcement Vs Negative Reinforcement -Positive Reinforcement – when a response is strengthened because it is followed by the presentation of a rewarding stimulus.-Negative Reinforcement – when a response is strengthened because it is followed by the removal of an aversive stimulus (electric shock to rats). Still involves a favorable outcome. (shock is removed if the rat presses the lever).-Escape Learning – acquires a response that decreases or ends some aversive stimulation. Any behavior that decreases or ends aversive stimulation-animal learns to escape shock in a shuttle box by running to the other compartment...
