The article by Ranganathan et al (2004) provides some relevant information. The authors discuss how it can be increased by two main factors, neural adaptation and muscle growth. They note how the motor skill acquisition literature supports the use of visualisation as an adjunct to actual practice as a means of improving performance: Research on motor ...

It has been theorized that it has to do with "visualizing" dreams, but the movements themselves are by virtue of the pattern of electrical activity as the waves travel between the Pons (in the brainstem), Geniculate nuclei (in the thalamus), and Occipital lobe. From PGO Waves PGO waves and REM sleep PGO waves are an integral part of rapid eye ...

I think there is a misperception at work in your question. There is a wide variety of objects that we never perceive in such a binary manner: colors, fruit (apples, oranges, plums, ...), weather, and basically every other concrete objects. The only things we perceive in a binary fashion are abstract ideas! Good versus evil. Liberal versus conservative. And ...

I would hazard a guess that some type of motor system interference is taking place when you visualize the movement versus visualizing an abstract shape. For example, Kilner et al. (2003) found that actions that are observed can interfere with incongruous executed actions. They had subjects make arm movements that were either similar or dissimilar to those ...

It's difficult to tell. Dreams are very hard to analyse scientifically since they can't be objectively measured, only self-reported. Dreams are notoriously difficult to recall after waking, so it's almost impossible to tell for certain. There are some self-report studies which do assert that some proportion of dreams are in black and white, but this pattern ...

There was an interesting study that compared practice by imagining a movement to practice by executing ot and found an increase in strength of ~35% for imagining it, compared to ~55% for actually doing it; additionally, they found an increase in cortical potentials corresponding to the increase in strength. They concluded that mental imagery alone ...

Yes, you can train your memory to be better at certain tasks, such as remembering numbers. For example Ericcson et. al. (1980) describe a university student who practiced memorizing numbers several times per week for twenty months and could then memorize and recall more than 70 digits reliably. I would not recommend such however if you are looking for ...

You might want to take a look at jsPsych, which is an open-source JavaScript library for building experiments. There is an example of running a visual categorization task in the documentation for the library.

Retaining a large number Can you hold the number 7859385 in your head for an extended period without the image of the number becoming distorted at any point? Long term memory of a single long number: Obviously a large proportion of people remember a few phone numbers that are at least as long as the number you mention. So for long term recall there are ...

As you mentioned, data visualization and visual stimulation in general, trigger a primitive brain response, which results in an easier comprehension and engagement/rejection process - a process more trivial than sensing and comprehending symbols. Thus, numerical information such as percentages, distributions, and relativistic data in general, immediately get ...

Maybe this paper would shed some light on your question : 5-HT and motor control: a hypothesis. The author has done some experiments on Serotonin systems within a cat's brain (Raphe Nuclei), and argues that Serotonin system is primarily involved in locomotion and (voluntary?) movement. Here's an interesting diagram from that paper: the firing pattern of the ...

Binary processes may be observed at various stages of intuitive and deliberative thought, which may in some cases plausibly be modelled as categories, but you’ll want to consider that on a case-by-case basis. Many of the relevant processes are binary simply because like formal logic, they involve toggle switches (true/false). Heuristics The simplifying ...
