An appealing activity can hold attention to within the normal range of 60 to 90 minutes for one session.
An activity that carries-over from morning to afternoon or one day to the next is remembered. Effective cause and effect connections learned recently are usually stored in long-term memory.
Activities that have inherent frustration or boredom problems are seldom continued because the concepts for the need to continue do not compute. The good of the group, business, or family unit is seldom regarded as a relevant reason for continuing to do an activity.
