I'm trying to use The Feigenbaum Scenario as a jumping off point for a discussion of David Grove's "The Power of Six" and it's implications for hypnosis, trance work and problem solving in general. One of the simplest yet elegant pattern is for the hypnotherapist to ask "And what's there now?" six times. This diagram models the client's process responding to this pattern, creating a hyperfocus on the symptom and a naturalistic healing response.

The answer may well be somewhere below the level of this line.
Love and hugs,

A number of classical studies in experimental psychology confirm that seven units or chunks (plus or minus two) is, in fact, a very common limit in human, sensation, perception, memory and performance (Miller, 1956). There are actually an infinity of physical wave lengths that make up the spectrum of ordinary light, for example, yet humans typically "chunk-out" or perceive only seven colors. Traditionally humans are regarded as having five basic senses but if one includes the more subtle varieties of kinesthetic and proprioceptive sensations the human number of conscious senses easily jumps up to seven but probably not much beyond that. Sperling (1960) found that people could remember about seven letters over a 1-second interval. He called this the iconic trace. Neisser (1967) found that the auditory trance, which he called echoic memory, had similar characteristics. Musical tone recognition has a similar range form the familiar octave scale to the more cerebral 12 tone scale. Is the number seven as a typical band-width in human such sensory-perceptual-memory studies and the seven chunks or paths we can see easily in the Feigenbaum period doubling sequence of Figure One simply a coincidence? Or is it another example of the seemingly unreasonable effectiveness of mathematics in modeling human experience in the most unexpected ways? The upper limit of about 15 units in conscious human perception illustrated in the Feigenbaum period doubling sequence of Figure One is supported by Kihlstrom (1980). Kihlstrom found that 15 items was the upper limit for post-hypnotic memory in low as well as highly susceptible hypnotic subjects who apparently achieved that performance limit by different routes.
An intriguing indication that seven is an important limit in complex human conscious functioning was discussed recently by Hofstadter (1995) who reports that since early youth he played and practiced extensively with anagrams. How many arbitrarily arranged letters can one juggle in one’s mind simultaneously until they suddenly rearrange into a meaningful word? He says, "Six letters, yes, but ten, definitely not." The same range is evident in juggling physical objects as well. The world record for juggling is nine balls. Ronald Graham, chief scientist at AT&T laboratories is a gifted juggler who reports that he can juggle six balls consistently and sometimes seven "playing around" (Horgan, 1997).
Further evidence of the significance of seven in complex human conscious information processing is in the extensive use of subjective rating scales that involve human judgments about everything from sense-perceptions to emotional experience. Research documents that most rating scales used in psychological assessment and personality testing (Caprara et al, 1997), for example, can be optimized by requesting discrimination on scale of about seven points. Subjects are asked to judge how happy or satisfied they are with a particular situation or life experience on a five to seven point scale that runs something like "1. Extremely Satisfied, 2. Satisfied, 3. Neutral, 4. Unsatisfactory, 5. Extremely Unsatisfactory." Recently developed cognitive-behavioral approaches for assessing a patient’s response to psychotherapy use a seven point "Validity of Cognition" scale to check on how much conviction a patient has that they have been helped as well as a ten point "Subjective Units of Discomfort Scale" to check on how much their pain or psychological discomfort has changed during therapy (Rossi, 1996a; Shapiro, 1995). Research is now needed to confirm the relevance of the Feigenbaum point and period doubling sequence in this apparently optimal perceptual, performance and subjective judgment limit range of 7 to 15 chunks of conscious experience on the path from order to chaos in human awareness. Freeman’s (1995) research on the nonlinear dynamics of the sensory-perceptual dynamics of smell, for example, would be an important test case.
At present we can only speculate about a number of open questions about the explanatory power of the Feigenbaum point and period doubling sequence in human experience. We can only wonder whether the significance of the number seven in gambling and many ancient mantic and mystical belief systems could have the same source in the limitations in our conscious sensory-perceptual-cognitive limits of awareness that is illustrated in the bifurcation diagrams of the Feigenbaum period doubling sequence. Seven items are about as much as we usually can hold in consciousness so we feel we know them and we are comfortable with them. When consciousness has to juggle more than seven items, dimensions or levels, we experience the stress of the heightened arousal of our neuroendocrine system and ultimately failure as documented by the extensive data supporting the Yerkes-Dodson law discussed above. On a cognitive level human cognition seems to become chaotic, dark, fearful, unconscious and perhaps unreal when we must hold in memory and manipulate more than 7 to 15 factors at one time.
The universality in the appearance of the Feigenbaum period doubling sequence in many complex systems have led to a number of highly speculative views about the possible significance of the Feigenbaum point for psychology, sociology and the humanities in general. Merry (1995, p. 37) suggests, for example, that the Feigenbaum point (about 3.7) is where systems cascade into chaos "where infinite choices create a situation in which freedom has no more meaning." We could generalize this to say that emotions, imagery, behavior and cognition and psychosomatic symptoms that have lost their meaning have somehow fallen into the chaotic regime within experiential space where our sense of reality teeters off the edge of comprehension or rationality. This suggests that beyond the Feigenbaum point inner subjective experience may fall into a sense of what is called unreality. Put another way, the Feigenbaum point may signal the division between primary process (irrational) versus the secondary processes (rational, ego processes) as defined in psychoanalysis. In this sense, the Feigenbaum point could represent a limit of our sense of voluntary ego control over our mental experience and behavior. The physicist uses the route to chaos as a way of describing turbulence in nature (fast moving water flowing over rocks, air turbulence behind an airplane etc.). Likewise the psychologist could describe the experience of confusion, disorientation and unreality as the turbulence of the mind moving past the Feigenbaum point into deterministic chaos.
Current cognitive science has developed these ideas further with research that documents how human ideas are grounded in sensory-motor experience and metaphor. This view is expressed by Lakoff and Núñez (2000).
"These metaphor studies mesh with studies showing that the conceptual system is embodied – that is, shaped by the structure of our brains, our bodies, and everyday interactions in the world. In particular they show that abstract concepts are grounded, via metaphorical mappings, in the sensory-motor system and that abstract inferences, for the most part, are metaphorical projections of sensory-motor inferences." (p. 101)
I now propose that the Feigenbaum point marks the transition between the explicit realm of conscious choice and behavior and the implicate realm of deterministic chaos on the unconscious level (Rossi, 1996a, 1997a, 1998b, 2000a). The Feigenbaum point is the limit of “subitizing” – the ability to tell at a glance whether there are 1, 2 or 3 objects in conscious (explicit) perception (Lakoff and Núñez, 2000). These 1, 2 or 3 objects in conscious perception correspond to the first, second and third bifrucation of the Feigenbaum Scenario as illustrated previously in Figure one. Peitgen et al. (1992) comment on the implicate (unconscious) and previously unknown aspect of how numbers operate in the iterative replays of nonlinear dynamics.

Hello Adrian,
Thanks for the belly laugh -- FYI -- I looked up the term bifurcation several years ago in regards to an article that I was reading about the myth of fingerprints... I haven't come across it again until today -- Freaking academics... Thanks to your WTF and the additional information supplied by Michael D. -- I get it- His jumping off point is about NOTHING to the 6th power... WTF? Love and Hugs,
Michael E.

Mitchell Feigenbaum Is a well known Mathematician , known best for his work in complex non linear systems behavior. There are points in such systens where the system changes from one behavior to another... Ie when a fluid goes from Laminar flow to a turbulent flowl. Those points are called bifurcation points. ie points where the accummulated influence of all system variables makes one behavior unstable and a second stable, Feigenbaum's work is very important in Chaos theory. My take here is that Rossi was using Feigenbaum's work to explain the most complex syetem he had ever encountered. The Human mind, Without a bit more input It would difficult to read Rossi's mind however one could speculate that he was showing that the more complex processes live in the relm of the "infinite domain of unconcious deterministic Chaos"
Fable did a great job of correlating what we know today in "real" space with Rossi's "Topologial virtual mind space"

Making them dizzy one post at a tine.
Ps Micheal The mathematical model of a finger print that results in the "CSI Positive match found moment on TV" relies heavily on the location of branches or bifurcation points on the fingerprint "tree".
