PSYCH 1 11 Bro Devon Marrott Chapter 7 Behaviorism John Watson shapes you into what I want you can t choose What is learning Acquired knowledge observation connections experiences of others There are 40 ways we can learn by For this class experience change longlasting in uence on behavior Habituation more you are exposed to some type of stimulus and then after words you are extremely sensitive to it For Behaviorism no study metal activity are useless Only observable behavior John Watson was in uenced by Ivan Pavlov Ivan Pavlov studied Dog s slobber He pared a sound with getting food so just hearing the sound would make the dog slobber for food Classical Conditioning Conditioning a reaction Paring two unrelated stimuli to get a response A amp B A by itself creates a response Pairing A with B then B will create the same response A meat It makes you slobber B bell Unconditioned Stimulus UCS this is what creates a natural response Unconditioned Response UCR a natural response Neutral Stimulus NS something that don t make a response before Conditioned Stimulus CS the NS created a response after it has been pared with the UCS Conditioned Response CR the reaction from the CS Extinction present the CS without the UCS the re ex stops occurring They can lose the connection Systematic desensitization baby steps Slowly face fears Spontaneous Recovery a random occurrence where a CS is presented with the USC after extinction Extinction is not permanent A boy who has conquered his fear of dogs a dog attacks him He is afraid of dogs again Little Albert amp Classical Conditioning Generalization things similar to the CS all create the response A German shepherd attacks me now afraid of all dogs Hairy things He was unable to Discriminate He couldn t distinguish similar but distinct stimuli Fear all in mind Watson wanted to Show that Pavolovian techniques work Emotional responses by stimuli Don t need to understand mental processes Classical Conditioning works on humans Biological Preparedness ice cream or spiders snakes or rodents Your biological make up lets you fear something that fear Operant Conditioning Condition Voluntary Conditioning A type of learning where consequences of behavior determine whether that behavior will be repeated in the future BF Skinner Found radial conditioning BIG Question How do you determine what will increase behavior or not Reinforcements things consequences that decrease a behavior There are different types of reinforcespunishments Positive simply put this is when you add a stimulus to a circumstance Positive Reinforcement you bring something to the table to increase a behavior Positive punishment you bring something to the table to decrease a behavior Operant Conditioning Negative simple put this is when you subtract or take away a stimulus Negative Reinforcement take a way a like Negative Punishment takes away a like Example You go 45 MPH in a speed zone of 60 mph a cop stops you pulls you over and gives you a ticket Positive Punishment should decrease the behavior You are driving your car without putting on your seatbelt The car keeps beeping at you so you put on your seatbelt Negative Reinforcement take a way a dislike Intervalschedules time Rationumber of time a behavior is preformed Fixed Interval reinforces given a set time period Variable interval times to be revoke changes Fixed ratio you provide reinforcement when they do behavior this amount of time get 10 get one free Variable ratio random changes in the amount of behavior required Sensation amp Perception needs attention It is easy to block out what you are not focusing on You in a bad mood you only think of bad thinks 30 long to do homework when you are on your phone The way you see things are not always the way it is We don t see the way the world really is The tipping tree sound is a perception If we are not in the forest when a tree falls it makes no sound Sound waves though phone sound is made in our heads Sensation vs Perception Sensation is a electrical signal to the brain Light sound pressure odor or taste Perception you assignment of meaning you are interrupting what you are sensing They work together Sensations sounds of your voice lines on a screen Know something happened Perceptions transforms my words into meaning Transduction when energy is converted into an electrical chemicals signal Gustav Fechner Founder of Psychophysics Psycho meaning mind physics meaning physical world Psychophysics relationship between the mind and world Implementation of psychophysics asking if saw hear felt Light sound touch Absolute Threshold amount needed to be detected 50 of the time The brain is designed to notice Change Perceptual process more efficient in detecting change Just Noticeable difference J ND minimal change to detect the change You know the change that happened This depends on the first stimulus AKA Weber s law Sensory Adaptation Brain noticing only change You get used to the stimuli it is like it is not there Prolonger stimulation declines signals stop firing Visual Magnetic spectrum Blue is short wave length Green is middle wave length Red is long wave length Physical vs Psychological Dimensions of light Length hue color Amplitude brightness Purity richness of color These three properties constitute physical and psychological dimensions of light Visual Acuity clear Vision
