The purpose of this study is to describe the use of Fibonacci numbers to model Erikson’s eight developmental stages and to formulate practical clinical implications. Using a new method, called the Fibonacci Life-Chart Method (FLCM), all prospective dates based on the Fibonacci sequence between January 1, 2000 and December 31, 2100 were identified. This study found the FLCM produced a developmental pattern characterized by eight recognizable stages. This finding constitutes a new classification of Erikson’s eight developmental stages. The present research provides support for Erikson’s epigenetic view of predetermined, sequential stages to human development based on the occurrence of Fibonacci numbers in biological cell division and self-organizing systems. This method may help identify populations at risk for psychological disorder, which would allow early intervention. However, a longitudinal study is required to establish its predictive power

Since the scientific method requires events to be subject to controlled examination it would seem that synchronicities are not scientifically investigable. Jung speculated that because these incredible events are like the random sparks of a firefly they cannot be pinned down. However, doubting Jung's doubts, the author provides a possible method of elucidating these seemingly random and elusive events. The author draws on a new method, designated the Fibonacci Life-Chart Method (FLCM), which categorizes phase transitions and Phi fractal scaling in human development based on the occurrence of Fibonacci numbers in biological cell division and self-organizing systems. The FLCM offers an orientation towards psychological experience that may have relevance to Jung's theory of synchronicity in which connections are deemed to be intrinsically meaningful rather than demonstrable consequences of cause and effect. In such a model synchronistic events can be seen to be, as the self-organizing system enlarges, manifestations of self-organized critical moments and Phi fractal scaling. Recommendations for future studies include testing the results of the FLCM using case reports of synchronistic and spiritual experiences.

This paper presents a literature review to determine whether precipitating causes of depersonalization (DP) and derealization (DR) correspond to the circumplex model of emotion defined by the dimensions of valence and arousal. DP/DR precipitators are reviewed and classified in relation to the four quadrants of the circumplex model of emotion. The findings indicate that the valence and arousal dimensions were significant predictors of emotions expressed in DP/DR precipitators. Implications are discussed with respect to the multidimensional nature of DP/DR, clarifying normal and abnormal DP/DR, and identifying needed areas of research.

This article aims to provide a brief overview of the relevance of new findings about the Fibonacci Life Chart Method (FLCM) for understanding synchronicity. The FLCM is reviewed first, including an exposition of the golden section model, and elaboration of a new harmonic model. The two models are then compared to illuminate several strengths and weaknesses in connection with the following four major criteria regarding synchronicity: explanatory adequacy; predictability of future synchronicities; simplicity of the model; and generalizability to other branches of knowledge. The review indicates that both models appear capable of simulating nonlinear and fractal dynamics. Hybrid approaches that combine both models are feasible and necessary for projects that aim to experimentally address synchronicity.

The Fibonacci Life Chart Method (FLCM) provides a framework linking development and spirituality. This study addressed the need for empirical research to test the hypotheses proposed by Sacco (Sacco, 2016). To address this problem, this study used case reports (N = 196) from the Alister Hardy Religious Experience Research Centre. The dynamical aspects of ages 11, 18, and 30 were examined as predictors of increased spiritual experience in adolescents and young adults. Results showed only ages 17 and 18 predicted a higher frequency of spiritual experience between ages 11 and 35. Age 18 was associated with a higher effect size (r = .27). This finding provides some empirical support for the FLCM as a predictor of spiritual experience, but not all hypotheses found support. Limitations to the study's design are discussed along with implications for future research.
