The Johari Window

October 30, 2015

sq_johari_window

As I considered my last post, I wondered if the intersecting centers of all my diagrams represented a “blind spot”, a fifth thing that I have been consistently overlooking. Searching on Google for the topic (besides finding the new television show of the same name), I stumbled on the Johari Window.

The Johari Window is a simple four-fold table that considers what an individual knows and doesn’t know about herself, versus what everyone else knows or doesn’t know.

So, the quadrants are as follows:

Hidden self: Known by self but unknown by others (also called facade)

Public self: Known by self and known by others (also called open or free area, or arena)

Blind self: Unknown by self but known by others (also called blind spot)

Unknown self: Unknown by self and others (unknown but perhaps knowable, also unconscious)

The idea is that the public self can enlarge, and include things from all three of the other selves, and so diminish them. Because having more openness in our selves, as well as less hiddenness, blind-spotness, and unknownness, is a good thing.

And I’m glad the blind spot is really just one of the four things of the Johari Window, so I haven’t left anything out!

The Brain with David Eagleman

October 27, 2015

sq_whowhatSpeaking of brains, “The Brain with David Eagleman” by neuroscientist and author David Eagleman is currently showing on PBS. The first episode “What is reality?” was pretty good, showing reasons why what we think of as an objective reality is really just a temporally delayed and conceptually constructed neurological fabrication.

The six episodes are titled:

  1. What is reality?
  2. What makes me?
  3. Who is in control?
  4. How do I decide?
  5. Why do I need you?
  6. Who will we be?

I wonder if the answers to these questions will pretty much be “the brain, the brain, the brain…”. Check your local listings and tune in to find out!

Books:

David Eagleman / The Brain: the story of you

David Eagleman / Incognito: the secret lives of the brain

David Eagleman / Sum: forty tales from the afterlife

David Eagleman / Why the Net Matters: six easy ways to avert the collapse of civilization

The Whole Brain Model of Ned Herrmann

October 20, 2015

sq_herrmann_brain

Are four different kinds of thinking performed in four distinct areas of the brain?

Facts: logical, analytical, fact based, quantitative (left cerebral)

Forms: sequential, organized, detailed, planned (left limbic)

Feelings: interpersonal, feeling based, kinesthetic, emotional (right limbic)

Futures: holistic, intuitive, integrating, synthesizing (right cerebral)

I’ve arranged the quadrants differently than usual. Some might want to see the diagram rotated 180 degrees, so that Facts are at the top. However, there are several reasons that I prefer this arrangement, with organized at top, synthesizing at right, kinesthetic at left, and quantitative at bottom. Part of my confusion is that I ordinarily want to place both Facts and Forms at top, and Feelings and Futures at right.

The images above remind one of the “Simon Says” toy! Blue, red, green, and yellow are often used in company logos. Three are pigment primary colors, and three are light primary colors. Do colors help one distinguish the quadrants?

The Carnot Cycle

October 8, 2015

sq_carnotThe Carnot Cycle consists of four steps:

  1. Isothermal Expansion
  2. Adiabatic or Isentropic Expansion
  3. Isothermal Compression
  4. Adiabatic or Isentropic Compression

The cycle is ordinarily plotted on two axes in two different ways: Pressure and Volume, in which case the cycle is a curvy quadrilateral and descending to the right, or Temperature and Entropy, in which case the cycle is a nice rectangle that emphasizes the isothermal and adiabatic (isentropic) aspects of the steps.
