Re: streams and groups

Concurrent and sequential grouping processes form events and streams of
events, respectively.

But segmentational grouping processes operate on streams of events to
form "chunks" or groups of events on the basis of discontinuities or
patterns of repetition or statistical properties of transition from one
event to the next. And hierarchical grouping processes form groups of
groups and so on.

So it depends on how you use the word!
