“…Others have extended the procedure to more complex behaviors of individuals (e.g., Buck, Baron, Goodman, & Shapiro, 1980;Shapiro, 1982;Zuckerman, Driver, & Guadagno, 11985;Zuckerman, Kernis, Driver, & Koestner, 1984) and to dyadic coaction in assembling tinker toys (Jensen & Schroder, 1982), but in each case, only the number of segments into which perceivers parsed the interaction was considered. In research with interaction specimens, only one interactant's behavior was clearly visible and barsed (Koopman & Newtson, 1981;Russell, 1979;Russell, Gowaty, Harland, & Martin, 1979;Strenta & Kleck, 1984), or the action unit boundaries were lqcated by the investigators themselves (Cronshaw & Lord, 1987). Again, only the number of observer marks was considered.…”
