Processing times vary from application to application depending on volume and USCIS staffing capabilities. The time it takes to process a DACA application can range from 60 days in some types of cases to 27 months in others. Unfortunately, because this application was only just released, we have no idea how long it will take for USCIS to adjudicate them.
Behaviorism is an approach to psychology that emerged in the early 20th century as a reaction to the psychoanalytic theory of the time. Psychoanalytic theory often had difficulty making predictions that could be tested using rigorous experimental methods.
A CR is the learned response (salivating) to the originally neutral (but now conditioned) stimulus. Ivan Pavlov's work on classical conditioning laid the foundation for behaviorism, the view that psychology should be an objective science that studies behavior without reference to mental processes. The behaviorists believed that the basic laws of learning are the same for all species, including humans.
