T-PATTERNS, THEME AND THE OBSERVER
Human Behavior Laboratory, University of Iceland, Reykjavik, Iceland
When measuring or analyzing continuous behavior records involving
real-time - for example looking for cyclical organization, typical
sequences and syntax, or behavioral profiles - it may be useful to
consider the possible presence of repeated hidden structures which may
be complex and of as yet unknown kinds. One basic type of hierarchical
time pattern, called a T-pattern, and the corresponding detection and
analysis software, Theme,
is proposed for the detection of hidden behavior patterns.
T-patterns are probabilistic, repeated, recursive (self-similar and hierarchical)
synchronic and/or sequential structures that may involve any number of individuals and
behavioral, physiological and/or environmental event types. Other structural types are
derived from the T-pattern type:
The search algorithm is described. Its main aspects are (1) detection
of critical interval relations between pairs of time point series and
(2) pattern construction, competition and selection. Examples of
T-patterns detected in human interaction studies are presented
including behavior coded with The Observer.
- T-markers are T-pattern components that indicate strongly the presence of particular
- A T-satellite is positively or negatively associated to, but not a component of, a
- A T-packet is a T-pattern with its satellites.
- T-alternation groups are sets of alternating mutually exclusive T-patterns or
T-packets within a behavioral stream.
