[Music] John B Watson known for establishing the behavior School of Psychology carried out one of the most influential psychology studies in the 1920s that would later on be something that would never be forgotten classical conditioning first experimented by Ivan pavlof was used on a dog when an unconditional stimulus was used to produce an unconditional response and a condition stimulus was used to produce a condition response This was later on extended by Watson in his demonstration of the little Albert [Music] experiment in Watson's experiment a little baby Albert was used to be conditioned he was born to a woman who was a nurse in the Harriet Lane home of invalid children although raised in a hospital environment Albert developed normally and was very stable [Music] Ivan pavlof was indeed able to condition a dog could Watson now do the same thing in humans now to the actual experiment [Music] itself first off Watson presented little Albert objects that he was not afraid of objects that Albert initially liked these included [Music] fire a [Music] monkey a dog [Music] a [Music] rabbit and finally a white rat Albert in particular likes a white rat from all these clips notice Albert's positive reactions and now comes the conditioning to start off the conditioning when Albert reached to touch the rat a loud bar was struck whenever Albert reached for the rat here Albert first off fell forward and was startled but he did not cry yet but he reached for it for a second time and heard it and then he started to cry Watson had indeed conditioned a fear response in little Albert Albert was then shown a rabbit he immediately cried and got as far away as possible from it then a dog was also brought in Albert did not cry right away he was acting cautious and it was only when the dog came right up to his head that he began to cry and tried to get away from it after this a seal fur coat was brought in Albert turned away from it and was agitated then Watson used a Santa Claus mask in which invoked an even more negative response by baby Albert from the previous experience from the white rat little Albert suddenly became afraid of familiar objects that had the same characteristics as the white rat this phenomenon was known as generalization Watson then wanted to test whether the reaction would carry over in a different setting the previous tests were done in a small dark room but now he was brought into a larger room he was presented with the same objects but did not show strong symptoms of withdrawal until the objects were paired with a loud noise wanted now wanted to see if if fear could be remained in Albert over a period of time so Albert was brought home and returned in 1 month when he returned he was tested with the same objects and paired with the same loud noises Albert indeed showed the same strong signs of withdrawal Watson once again proved that he could condition fear into baby Albert Watson concluded that phobias were most likely conditioned responses the little Albert study is extremely important in Psychology and other disciplines it has inspired other important researchers of the past and continues to impact the direction of the psychological investigation today and opponent process Theory tells you about Vision less complex than math and cellular division hering said there were three pairs of color receptors including red green yellow blue black and white colors don't know if I could ever be without sight cuz it comes me and in time I know that we both sing sensation all we need cuz you're the eye to my you're the color to my blindness you're the black to my white according to psychologist cuz you're the eye for me for me and I'm the eye for you for you you take the both of us of us we're the perfect too we're the perfect too we're the perfect too so much that I can do yes we the perfect too you know that I'll never doubt you and you know that I'll think about you and you know I can't live without you
