Script theory, developed by Roger Schank, is orientated mostly on structure of knowledge, especially on representation of more complex event sequences in memory.
There are several definitions of scripts like: coherent sequence of events expected by an individual in a particular context, involving him either as participant or as an observer (Christopher Puto), or a “mental picture plus caption” representing the action sequences, participants, and physical objects found in a situation (Robert Abelson).
Scripts consist of a sequence of actions or events necessary to achieve a goal. They also if necessary include relevant people, locations or objects.
