Mike, Terry, Gunnar and all

I was away and missed this exchange so this is a bit delayed.

First, it is nice to see someone looking more deeply into mental functioning as it may relate to design and imagery. In response to Mike's remarks, I am concerned that as designers we tend to focus too closely on perception and fail to adequately consider how it interacts with cognition, language, and design thinking itself. The most useful book relating visual perception to broader thinking  that I have found is Wet Mind: The New Cognitive Neuroscience by Stephen Kosslyn and Olivier Koenig, especially their section on Visual Cognition. Kosslyn, a renowned authority on perception,identified some essential mechanisms such as attention shifting systems, property look up systems. etc. that have informed the modes of thought in A Theory of Design Thinking. I highly recommend it as a bridge from perception into neuroscience.

This large area, topographically arranged, is were different kinds of visual information are processed simultaneously. An interesting video of this happening in real time in a live monkey brain can be seen at: http://videocast.nih.gov/summary.asp?Live=11769  The monkey demo begins at minute 10:00.

The outcome of these process ‘binding’ occurs in which neurons define regions in which the lateral occipital cortex is involved. Regions lead to object recognition. Object recognition moves to the prefrontal cortex from which signals are sent back to previous areas for task oriented action.

I am defining it as using one’s mind (leaving aside the whole brain/mind debate) to consider, identify patterns, make connections, and reach conclusions. I ‘think’ the processes above fit that perfectly well. Colin Ware (2008, p. 45) states: “In some ways, pattern finding is the very essence of visual thinking, and often to perceive a pattern is to solve a problem.”

This year in reading about the neurobiology of creativity (Takeuchi, et. al. “The Association between Resting Functional Connectivity and Creativity". 2012) I found divergent thinking and connectivity are key factors. Sketching visually I think we will come to find, stimulates these processes, but that seems some way off from a science perspective. 
> 
> I’m happy to continue our exchange about this offline as it seems no one else is particularly interested. I'm particularly interested in a search for the things visual does better than math. Since my expertise is in what visual does, and you seem to have more expertise in math than I do, perhaps together we can help define what each does well, better than the other. Alone I can only tout how MY visual thinking is better than MY maths - an unfair comparison. One suggestion to get started is that visual sketching can express less defined, more vague thinking. It can do this quickly and easily. At the fuzzy end of problem solving this seems like an advantage over maths. Also, related to the processing above, much of visual perception happens before conscious thought (bottom-up), but is influenced by it (top-down). We can 'tune' our neurons to be more responsive by 'thinking about it.' This seems particularly well suited to rapid divergent thinking and connectivity of creativity as we first find patterns then shift our thinking to 'see' it differently, literally. All this in fractions of a second. This seems another advantage over maths. But I'm starting to ramble...
