Fibonacci Life Chart Method

 The Fibonacci Life-Chart Method is an application of the Fibonacci sequence to developmental patterns.

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. Examples of Fibonacci patterns can be found in nature.  For example, the number of leaves on a plant or the number of branches on a tree will often follow the Fibonacci sequence.

 

Psychologist Robert G. Sacco (2013) applied the FLCM to Erikson’s eight developmental stages (1982) and 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.
