 Come senescence and retirement, behavior is more stable as the individual has often established their social circle (whatever it may be) and is more committed to their social structure.With the advent of the field social cognitive neuroscience came interest in studying social behavior's correlates within the brain, to see what is happening beneath the surface as organisms act in a social manner.Although there is debate on which particular regions of the brain are responsible for social behavior, some have claimed that the paracingulate cortex is activated when one person is thinking about the motives or aims of another, a means of understanding the social world and behaving accordingly.
