Now Print!
The ''Now Print!'' theory, first proposed by Robert B. Livingston in 1967, is an attempt to explain the neurobiology underlying the flashbulb memory phenomenon. The theory argues that a special mechanism exists in the brain, which issues a ''now print!'' order to preserve moments of great personal significance.
==Theory==
The ''Now Print!'' mechanism could have evolved because of the selection value of permanently retaining biologically crucial, but unexpected events. The same mechanism may account for both the enduring significant memories in which one has played the role of protagonist and those in which one has only been a member of an interested audience of millions. (Brown & Kulik, 1977, pp. 97–99).
The circumstances of a ''now print!'' reaction are described by Brown and Kulik: "First comes the recognition of high novelty or unexpectedness; then comes a test for biological meaning for the individual; if this second test is met, there follows the permanent registration not only of the significant novelty, but of all recent brain events."(1967b, p. 576).
Brown and Kulik proposed that the ''Now Print!'' theory delivered an evolutionary advantage by giving rise to very specific and durable memories of events of high personal consequence. Such memories might be used vicariously in preparing effective avoidance and approach strategies and so aid in survival. “The mechanism is activated when a given event occurs unexpectedly and has biologically significant consequences for individual’s lives so that people are ready to recognize similar events in the future,” (Lanciano, Curci & Semin, 2010). When this happens memories for these events contain an abnormal amount of sensory and peripheral details that give the impression of accuracy.
