Humans have been observers of behaviors since times immemorial. As social animals, we have that innate sense to observe others and then adjust our reactions. There are two broad categories of #behavioralscience, neural (e.g. psychology, behavior analysis, or semantic networks) and social (e.g. social networks, agent-based model, or microsimulation).
Let's take #behaviormodification, a core #PBJAM principle from #behavioralscience that took shape under the able efforts of Pavlov, Skinner, Thorndike, and Watson from 1920 to 1960. Some of the key characteristics of this principle are:
Focused on behavior and not on personal traits or characteristics
Precise descriptions to effect sustainable change
Implemented by people in everyday life and not instructional or theoretical
Emphasizes current environmental events than the past
Rejection of hypothetical underlying causes that can't be measured or manipulated
#behaviormodification principle and structures allow #PBJAM to cut through the fog of #analysisparalysis often faced in #professionaldevelopment. Emphasis on actions that can be taken in everyday life allows #PBJAM participants to experience #tangible change. Pursuit of precision while describing levels of satisfaction, targets and goals make the #PBJAM experience highly effective.
PS: Here is a good reference to behavior modification.
