When you are discussing visual communication is this found in a conversation that is face-to-face, a synchronous conversation with a tool similar to Zoom, or an asynchronous video communication thread? How are you defining visual communication?

Visual communication as defined in Visual Literacy is, body language, object language and visual art. In my belief it is anything that communicates primarily through a visual means. Video conferencing wouldn't fall under this definition as it is only an conduit. In the same way that a phone does not add to a conversation.

In my opinion, how visual information is processed in a persons brain (mind?) depends on their preferred style of processing information. Body language and visual art I understand. I will not address object language as I am unsure of how you define that.

Take a piece of jewelry. I have had sold jewelry to people who choose based on how it looks (the majority of buyers), and I have sold jewelry to people who are in some way concerned how it feels on them. About 10% or more of buyers voice this as an item to consider.

Everyone speaks with body language. It is important to know how to see it and react to it. Visual communicators can tend to very loud body language. Some people who are very visual will only perfunctorily try on an item of jewelry being more concerned with how it looks.

Those who are not visual communicators will try on a piece of jewelry and play with it for quite some time to see how it 'feels'. Body language is very subtle in my opinion with people like this.

So does this tie in to your question " Do changes to visual thinking create visual learning?". It does in my experience. As I work with clients, I listen and watch their reactions to better tailor their experience into something that is educational and fun.

The same rules apply when I am presenting on my areas of research (aiglets...). I try to use audible, visual (props and body language), and tactile examples to pass around when I present information.

For those who are primarily visual learners, and thinkers, small changes in how something looks can make a large change in the information received. For others, who are more tactile or auditory learners, not so much.

I look forward to following this question and seeing what others say.

I would argue that we are all visual learners. Some of us are more aware of our vision than others. It operates secretly and is obscured by the data that it provides. Object language is the visual language of objects. What to they communicate to us? It is similar to aesthetics. The difference between aesthetics and object language is that aesthetics is a study and object language is a phenomenon.
