The Fibonacci sequence is a series of numbers where each number is the sum of the two previous numbers. The sequence starts with 0 and 1, and then continues with 1, 2, 3, 5, 8, 13, 21, and so on. The number of leaves on a plant or the number of branches on a tree will often follow the Fibonacci sequence. Robert G. Sacco (2013) developed the Fibonacci Life Chart Method (FLCM) and applied it to Erikson’s eight developmental stages (1982). Sacco presented a revised age-stage chart. Following is a quote from Sacco’s discussion (p. 143). The results of this study provide support for the assumption of an eight-stage theory of development. The FLCM serves several useful functions. These include: (a) substantially improving understanding of the eight developmental life stages proposed by Erikson, and (b) the use of it as a tool for timing of interventions.
