PSYC 1000 1st Edition Lecture 12 Outline of Last Lecture II. Behavioral LearningIII. Classical ConditioningOutline of Current Lecture IV. Operant Conditions V. Schedules of Reinforcement Current LectureOperant Conditions: BF Skinner Positive reinforcement: the addition of a reward following a desired behavior.Positive punishment: works by presenting a negative consequence after an undesired behavior is exhibited, making the behavior less likely to happen in the future.Negative reinforcement: which strengthens a behavior by taking away a negative outcome as an effect of the behavior.Negative punishment: happens when a certain desired stimulus/item is removed after a particular undesired behavior is exhibited, resulting in the behavior happening less often in the future.Applied RemovedDesirable Positive Reinforcement Negative Punishment Undesirable Positive Punishment Negative ReinforcementSchedules of Reinforcement Fixed Ratio Rat example, after every 10 levers pulled the rat would receive food pellet. These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Fixed Interval Schedule Give the reward after every one-minute, even if they pull the lever more, must wait 1 minute to get food, rats do a slower rate of response.Variable RatioReceives reward after random times, like 2, 5, 7, 9, 12 minutes, rats cannot tell when they will get the food, Variable Interval Receives reward at random times, a certain amount of time must pass, but the time is always different. Shaping: when you reinforce the subject when they get closer and closer to the target behavior, slowly building. Ex. Kid trying to touch podium, “good” pigeons playing ping pong, rats playing
