Closure
Concerned with human grouping activity into meaningful “chunks”
Closure experienced at the end of each “chunk”
- brain senses achievement and seeks rest!
Sense of closure increases with significance of “chunk”
Requires retention of all necessary info. in STM
- disruption within closure degrades performance, increases error etc.
Size of chunks increase with experience/familiarity
- novice views single UNIX command elements; expert sees whole scripts
