How to Speak to a Robot

The newest wave of interest in Artificial Intelligence is different from the two others I have experienced. In the mid 1970’s, I, and many others became enamored with the idea that we might actually be able to build tools that could think for themselves. Imagine, I thought…” a drill that knows where to drill and can get up to do it by itself while I sat sipping a Pina Colada on the beach!” This admittedly weird example may at first seem useless until you fill in the context behind it. The 1970’s ushered in a kind of microelectronics revolution of sorts in the United States. At that time I still owned a tube tester and needed it from time to time. Transistors were becoming “old school” and new integrated circuits began to be the rage. My Radio Shack soldering iron and stacks of old tube driven radios and televisions (from where my back stock of parts came) were quickly replaced by shelves bursting with those dark blue Integrated Circuit manuals from places like Hamilton Avnet and Texas Instruments.

Are we some other society’s Experiment in AI?

Here’s something to consider. I am constantly having to change  the way I think to break down boundaries that my limited worldview (in this case universe view) have set on my mind. A few years ago, the notion that we live in a “MATRIX-Like” simulation gained popularity among scientists. My initial response was to reject even the possibility of such a notion. However, my thinking this week has led me to now consider this question as a distinct possibility. What if we are  someone else’s experiment in developing an artificial intelligence? Since we know that time is an artificial construct, this suddenly opens up the possibility that we might just be ants under the looking glass being studied by an advanced race.

Do you have an opinion? I’d like to hear what you have to say on this subject. Thanks   Dr. Andy.

Where will the Path towards Artificial Intelligence Take Us?

I have worked in for most of my fifty-year scientific career in artificial Intelligence (AI)-related fields studying both human and artificial processing methods. With the recent resurgence in interest in AI in our society, I have been surprised by how easily humans have accepted the inevitability of AI as a part of our lives. As we blindly push forward, concepts such as autonomy, machine control and decision-making, risk and machine ethics are all being tossed around without much thought for the long-term implications for the human race. I thought a few words about where I believe we might end up might be interesting. [The following excerpt is taken from a book I am currently writing.] Continue reading “Where will the Path towards Artificial Intelligence Take Us?”

A Breakthrough in the Regulation of Human Cognitive Load: Decoding the Language of the Brain

Many of us grew up thinking about the senses (eyes, ears, nose, skin, and mouth) as the information/signal gatherers, the brain as the control center and the nervous system as the pathways that attach the brain to the muscles and internal organs. Although we now know that this simplistic view of how information is shared within the body is not exactly correct, for the sake of this discussion, we will use this classis paradigm as the basis of our discussion (Figure 1).

Nutraceuticals—Really?

If you study the human body you start to realize that the use of drugs to fix or control disease is a brute force method of healing not far removed from the use of leaches to bleed patents as far back as the 3rd century AD. Even today, in what we call “modern medicine” The U.S. Food and Drug Administration in 2004 approved the use of leeches for localized venous congestion post -surgery, recognizing them as a form of living, medical device. My point, is that as proud as we are of modern medicine, its really far behind where it should be. In my opinion it’s because we would rather use drugs to treat symptoms, rather than attacking the source of the problems that cause them. Continue reading “Nutraceuticals—Really?”

49 Years ago. The World Was so Much Different Then…or was it?

Left: 1971 Rhein Mein Germany; Right: 2020 Huntsville, Alabama

I remember when the picture on the left was taken. I am standing next to my friend Fritz Thomas. I don’t remember who took the picture but I remember posing for it as though it was yesterday. This month I put my uniform back on for the first time in 49 years. I don’t know what I was expecting. The boots I wore in the service were the most comfortable shoes I ever wore. In fact, I wore them after I got out of the Air Force for several years until they finally wore out completely. Fritz and I both were sent to Korat, Thailand in 1972 to be part of the 388 Combat Support Group. I’ll never forget that Fritz met me at the side of the C-130 when I landed at Korat on the flight from Da-Nang Vietnam. We were both aircraft electricians and for a time both worked in the flight line battery shop at Korat. In 1972 the Air Force started spraying around the perimeter of their bases in Thailand with Agent Orange. When the 50-gallon drums were emptied of rainbow herbicide they brought them to us so we could use them for battery acid and soda water. As a result of that direct exposure, 49 years later we both have Parkinson’s disease and we stay in touch as much as we can. Continue reading “49 Years ago.

PART II: The Impact of Important New Upgrades to Cognitive Load Theory on The Performance of Warriors Using Hi-Tech Systems

Introduction

In part I of this blog I laid the foundation for my claim that the Military needs to fully understand the recent upgrades to cognitive load theory (CLT) or risk wasting money, time and the performance improvements promised by new military technology. We followed the development of the theory from its genesis by John Sweller (1988) through 2012 when upgrades, based on research in the field of evolutionary educational psychology (Geary, 2008; Paas & Sweller, 2012) suggested that different kinds of information (social and cultural) are handled differently in working memory. Finally, we introduced new research that found that cognitive load could be actively controlled through the addition of specific visual stimuli that takes advantage of the brain’s bias towards socially-relevant information (Bevilacqua, Paas & Krigbaum, 2016: Bevilacqua 2017). It was also found that this bias works differently for males and females (Bevilacqua, 2017; Castro-Alonzo, et al., 2019).

PART I: The Impact of Important New Upgrades to Cognitive Load Theory on The Performance of Warriors Using Hi-Tech Systems

Background

When John Sweller wrote his seminal paper on Cognitive Load Theory (CLT) in 1988 (Sweller, 1988) he was primarily interested in the differences in how experts and novices approached problem solving for learning and education. As the community of interest grew, researchers realized that how the information was presented to a learner (problem-solver) could help to guide problem solving and therefore improve learning and retention. This research occurred at a time when the age of digital communications and computer usage was exploding across the globe. During this time Researchers such as Richard Mayer (Mayer & Moreno, 2003) attempted to develop heuristics that would help people optimize the display of digital information for learners. Still others (Lavie, 2010; Lavie, Hirst, de Fockert, & Viding, 2004) started looking at the other side of the equation, i.e., human attention and understanding, to try to understand how that attribute of the human eye-brain system could best be guided to make more efficient use of the displayed information (Figure 1). That research determined that to focus attention on the desired information, the distracting effects of all other information must be reduced or removed. This led to more research in ways to optimize low cognitive load learning and work environments.
