... The diagonal lines show where the data points would be if the information provided by the neurons were fully divided between the two variables on the axes. The data points lie below the lines because not all of the response can be used, i.e. one response variable can’t be exactly split between two s ...

LEARNING and Classical Conditioning
... Learning is the process of acquiring new and relatively enduring information and behaviors. One way we learn is by associative learning which is when we learn that two events occur together. The other way is cognitive learning which is the acquisition of mental information, whether by observing even ...
