The concept of perezhivanie, Vygotsky's "last word" on psychology, has been among the most difficult of his theoretical constructs to define and operationalise in research. Drawing on close analysis of key texts, this article identifies and examines three defining attributes of "perezhivanie" found throughout Vygotsky's works.…

This study was designed to determine whether infants could perceive action role reversals when the direction of action is ruled out as a cue; whether infants consider inanimate, nonpotent objects to be unlikely agents; and whether both these discriminations could be reliably reflected in the heart rate response.
