How Pavlov's experiments with dogs demonstrated that our behavior can be changed using conditioning. One of the most revealing studies in behavioral psychology was carried out by Russian physiologist Ivan Pavlov (1849-1936) in a series of experiments today referred to as 'Pavlov's Dogs'.
Difference between Generation X and Generation Y. Generation X and generation Y are two categories of people that are defined according to the idea that different generations can be separated from one another according to when they were born and to the cultural influences that have shaped them.
Generation X is a term now used to describe a cohort of people born from roughly 1965 to 1980. Some of the alternate birth ranges which have been suggested for Generation X include: the late 1950s and 1960s, 1968 to 1979, 1964 to 1980, or 1961 to 1981, Source(s): http://en.wikipedia.org/wiki/Generation_X.
