But it’s not the way we humans teach and learn Human Learning Learning in the “real world” is social . – Learning as occurs in human societies is social and cognitive – Last time: speech learning in infants as an example – Social cognitive learning is only now being investigated in animals—mainly primates and a few social mammals Pavlovian Conditioning: learning is guided by sensory associations Ivan Pavlov www.radford.edu/~jmontuor/XPsyc%20333/333PPClassical_ conditioning www.radford.edu/~jmontuor/XPsyc%20333/333PPClassical_ conditioning

Contingency (if…then…) Contingency represents the number of times that the CS is paired with the US. Maximum contingency is obtained when the CS precedes the US on every trial. (100% association) The less often the CS precedes the US, the weaker will be the conditioned response. If the CS precedes the US on 50% of the trials or less, little conditioning will occur. Bottom line: associative learning, including Pavlovian/classical conditioning is about making predictions and expectations.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
