A word about Prevention Protocol:

A lot of mental health issues are exacerbated because of stigma.  People shun others whose problems they don't understand.  People avoid asking for help for fear of being shunned.

Fighting stigma takes multiple approaches. Not just advocacy, but positive and accurate exploration through literature, art, and popular entertainment. Acceptance needs to be modeled, not just protested for. You need to show people what it looks like so they know what works.

Prevention Protocol is meant to show a solution, which in turn will make it easier for people to help when someone is suicidal at work.  Which is the main reason why it is free and will remain that way.

Hopefully, with time, I will write more stories that give people a better understanding of mental health issues in a non-threatening way.  I have a few in Scheherazade's Box and several sections about trauma and grief in A Tragic Tapestry, which I hope to have out soon.  Of course, the mental health issues are subplots, unlike the story in Prevention Protocol.

It is my hope that if people get exposed to mental health issues in non-stigmatized ways, they will take the lessons more to heart and be less fearful of the subject.

Qualitative and Quantitative research - ISO Audits

It occurred to me after my last post that many people might not know the difference between qualitative and quantitative research. In a nutshell:

Quantitative Research - research where the results are all distilled down to numeric quantities. It is usually recommended during the latter phases of a research project. Questions such as "how many people follow the procedure manual while doing this task?"; "how often is this store robbed?"; or "what is the percentage of improvement in depressed people while taking this medication versus a placebo?" are things answered through quantitative research.

Qualitative Research - is research where the results consist of words, descriptions, and images. It is usually recommended during earlier phases of research projects. Questions such as "what procedures are being used in production?"; "who is responsible for security?"; and "what are the side effects of this medication?" require qualitative answers.


The ISO compliance audit is a qualitative research process. Things like percent of damage returns or wasted man-hours are secondary concerns. What is important are things like:

Do the procedures documented in the process manuals accurately depict what is being used on the floor? Some companies create procedures that have little to no resemblance on how the worker actually does the job. Sometimes it's because the workers just don't care, but other times it is because the documented procedure is not adequate, whether it's out of date, an efficiency problem, or safety issue. It's hard to improve something if you aren't documenting what works and what doesn't.

How are data measured, recorded and analyzed? This is something you should ask yourself whenever you read a research document. All the number gathering in the world is meaningless if the numbers are not handled correctly.

Areas of responsibility and accountability. It's not enough to say "Yes, someone is accountable for this." An ISO auditor has to find out who is the person. Is it the QA manager or the production manager? Is it the financial department or procurement?

Feedback flows. How does the company get customer feedback? How can employees give feedback?

And so forth... The ISO system is developed to help companies not only prove their ability to produced quality products, but also put in place processes that help companies improve their performance and stay competitive in changing markets. It is qualitative in nature because you can't compare diverse companies through the use of quantitative data. It's been tried and it was ineffective. However, that's not to say that there is not a quantitative element in ISO certification. You still need a way to track how effective procedures are and what areas need the most work on.

Good researchers start with indepth qualitative research and then do the quantitative research. Anything else is not good research.

The Importance of Qualitative Research

For five years I worked as a Quality Assurance Technician/Specialist for a major corporation, before I took time off to be a stay at home mom. Most of my work revolved around routine quantitative tests and research at the national QA lab. However, I had the opportunity to work on some investigative research during that time. One nice thing about doing internal research for a major corporation is that you don't really have the option to put a spin on your test results. There is always an external bottom line that you are accountable to. While in the academic and sales world, some researchers can talk circles around their results and still retain their positions, in the quality assurance world, if your research is faulty, it shows in the product and in the accounting. Faulty quality research costs a company money and can get you fired.

During my time in the QA field, I learned several things about research. First off, it's extremely easy to end up measuring the wrong thing. I cannot emphasis that point enough. During my first year, I was the technician for a new engineer, and he and I found this out firsthand. We even had a strong disagreement over one test on this matter. I noticed that there was something weird going on with my test results and brought it to his attention. He wanted to wave it away, because my results were confirming his hypothesis. If there is one thing I hate doing, it's fudging data. So I told him flat out that it may prove his hypothesis, but as a technician, I was not going to stand by the results. He finally told me that I could repeat the test. I'm sure he was expecting me to back down because he knew I hated doing that particular test, especially for the number of repetition he was asking for. Instead I agreed and then after clarifying that I would be doing the test the same way as I had the first time, I asked if I could switch the order of the samples. He agreed and the next set of results showed that I was right. To the engineer's credit, he then accepted that he was mistaken, listened to my observations, and figured out what actually was going on - and was able to confirm it. A few years later, he borrowed me back from the manager I was then working with, because he had a $5 million bizarre problem to solve and he wanted a technician who would tell him if things were looking screwy.

Between those times I worked for that one engineer, I worked for a manager who had been a university professor at an engineering school before working for the company. I was given the task to compare two types of color measuring machines. (Since, to the best of my knowledge, no one reading this blog is in the flexible packaging field, I'll dispense with the technical names.) The newer one was developed for the auto industry and we needed to see if it could meet our needs. Before I could even begin to compare the two machines, I had to do a search of the literature before I could even have an idea what I was actually testing. I also talked to our R&D packaging scientist and the manufacturer's representatives. I even resorted to going through my mother's old books on painting with color, which provided me with a lot more on the subject than I originally expected.

In short, under the direction of my manager, I did qualitative research before I started anything quantitative. That's because it's the qualitative research that shows you what you should be measuring. Most people don't understand that. When I took the research methods class for my masters, I really had to bite my tongue not to go into an impassioned rant over the necessity of qualitative research as a precursor of decent quantitative research. The R&D scientist I worked with for the color project was brillant and a good deal of his brillance came from the fact that he did his qualitative research before he launched his quantitative research. In the quality assurance world, measuring the wrong thing costs money and jobs. There's no time for weak research based on "well, this sounds like this might be the cause." You need to have solid reasons for your choices before you can even start your tests and in the corporate world, those choices are challenged more stringently than what I've seen so far in the academic world. Of course, this may not be the case on the doctorate level. I hope that is the case when I go back to school for my doctorate, because through my quality assurance training I have developed an obsession with doing thorough background research before I develop a test procedure. This is the reason my capstone is basically a literary review, because I would rather do a thorough literary review than a half-thought out series of qualitative tests.

Actually, I'm not sure I can even bring myself to do testing before doing a literary review. You see, my last job with this company was manufacturing defects coordinator. I was transferred to a plant to help them reduce their packaging defects. The plant management was convinced that the suppliers were sending them inferior flexible packaging. I spent the first few months testing roll stock to confirm that this plant was getting the same quality of packaging that all the others were. The plant manager didn't take that very well and I was told that I had six months to find out what the problem was or my job would be eliminated. For the first two or three months, management kept giving me things they wanted me to test for them as possible causes for their high defect rate. Out of pure preservation, I began to study other possible contributing factors. I used my connections with the national lab to talk to the engineers who trained the trainers who taught the packaging machine operators how to do their jobs. These were also the same guys who followed up on the quality of the machine maintenance people. They assured me that the trainers and the plant maintenance people where I was at were top notched. I talked with the trainers in the plant and made friends with the maintenance guys. It was obvious from their dedication and knowledge that they were, indeed doing their part. It was also obvious through the observed quality of their work, which they gladly let me examine.

I knew we were all missing something, but I couldn't figure out what it was while doing all the tests to make management feel better. So, I took a stand and reminded them that they brought me there because I was a specialist and if they were going to make me accountable for this, then they needed to let me do the job I was brought in for. Again, the plant manager was not impressed, but I figured I was doomed anyway with the way things were going, so I stood my ground. He said he wanted me to do line audits. In the past, I had been doing warehouse audits because no one wanted me to interrupt their production flow. I told him that I would do it on the grounds that I created my own audit criteria. To make everyone happy, I put in every common packing flaw that could be seen by a non-destructive inspection. However, well aware that I still had no idea what the real problem was, I made sure I made a space on my audit forms for comments - just in case I stumbled across a clue or two.

Then I started my line inspections. I hadn't even finished my first bag inspection, when the packaging machine operator came up to me and asked in a surly voice if he was going to see my results right away or was he going to have to wait until his manager yelled at him about them. Dumbfounded, I said, "You don't get my reports?" After he confirmed that was the case, I asked him if he wanted me to make him a copy and bring it back to the line as soon as I finished with everyone. He agreed. During this time, a light went off in my head, as I reviewed the stories I knew about how my dad and maternal grandfather managed their employees. The packaging machine operators weren't getting enough feedback. And if they weren't getting enough feedback, then chances were, based on the first guy's comments, they weren't getting any positive feedback at all. So, in my "comment box" I mentioned specifically what was right about the bags I auditted.

I asked every machine operator if they wanted my reports directly from me. All of them said yes. I instituted what I called my positive feedback program. Sometimes, before I even started checking for flaws, I would write down what looked good on the bag. After a week of this, the machince operators started looking forward to my audits and asked for my opinion on some of their issues. During the third week, I came across a perfect bag. I asked the machine operator if I could display it in the lunchroom with his name attached to it. That bag was followed by others from other machine operators. Three months from the start of my audits and positive feedback, the manufacturing defects numbers had dropped 70%.

It wasn't the quantitative studies that found the issue. It was the qualitative investigation that did the job. The quantitative studies only backed it up. International Organization for Standardization has proceedures it dictates for those companies wishing to be ISO certified. I've actually taken classes on ISO certification a few years back and I can assure you that their quality standards take into account the qualitative aspects of processes too. I'm tempted to pull out my books and give examples, but I think I'll save that discussion for another post.

Subliminal stimuli processing

About a month ago, a friend of mine in the psychology profession, who is a fan of Derren Brown, had me watch this video:



It is an interesting experiment and a very well done one. I like the fact that they included two subjects who were internal controls. I think that it would be a very good idea to repeat the experiment for a larger population, with controls who hadn't even laid eyes on the CD they sent out. Another example of subliminal priming is Derren Brown influences two gentlemen who work in the US advertising industry. Even advertising professionals can be influenced. This video includes the explanation of how he did it. You might want to check out the UK version too.


Another interesting study is the Duke University Subliminal Ad Experiment:



Research=> Automatic Effects of Brand Exposure on Motivated Behavior: How Apple Makes You “Think Different”

This article first examines whether brand exposure elicits automatic behavioral effects as does exposure to social primes. Results support the translation of these effects: participants primed with Apple logos behave more creatively than IBM primed and controls; Disney-primed participants behave more honestly than E!-primed participants and controls. Second, this article investigates the hypothesis that exposure to goal-relevant brands (i.e., those that represent a positively valenced characteristic) elicits behavior that is goal directed in nature. Three experiments demonstrate that the primed behavior showed typical goal-directed qualities, including increased performance postdelay, decreased performance postprogress, and moderation by motivation.


What does this mean, besides the fact that humans can be easily manipulated? These experiments, tricks, and studies show that our minds process information on an unconscious level. In fact, it could be argued that some intuitive may come from this subliminal data processing. (Some intuition comes from the capacity to process things in a global manner.) This ability probably wasn't developed as a means to be influenced, though it probably helps with social interaction, but there is some evidence that it can improve our safety. The Gift of Fear written by security expert Gavin de Becker, suggests that the hunches and gut feelings we sometimes get come from picking up on certain cues that our conscious minds miss. It is a very easy and fascinating book to read, despite it's length. I highly recommend The Gift of Fear to anyone interested in personal safety or even just human behavior.

The way I see it, our minds have to regulate some of the processing of stimuli to the subliminal level because if it was all conscious, we'd get overwhelmed. And while this process can have some undesirable results, it does serve some very important functions.

Reasons why kids are sometimes better at technology

After finishing my masters, I decided I wanted a break before going on to a doctorate program. So at the moment I'm employed doing technical troubleshooting over the phone. While in training, the truism about children being better at technology was brought up. Our trainer confirmed that children were indeed easier to troubleshoot with - because they were better at following directions and did exactly what you told them and nothing more. As a parent, this sounded rather counter to my experience; however as a technician, I've found out that she was right. More often than not, the children I've talked to (after getting the parent's permission) weren't really all that more knowledgeable than Mom and Dad. Of course, as we're often reminded, the customer who actually know what they're doing are usually the last ones to call for technical support, but still there is a pattern between the two populations.

1. Children have less preconceived ideas on how something is supposed to work. It never fails to amaze me the expectations people have of electronic equipment. Despite the fact that they have to replace light bulbs in their homes, flashlights, and cars, there are people in this day and age who still think that electronics should last forever. The fact it comes with a time-limited warantee is completely lost on them. But even more frustrating is the customer who thinks they know how a piece of equipment works and tries to jump ahead of the technician. Children don't do this. They let you tell them what the next step is - even the teenagers.

2. Children focus more on the task and less on the embarrassment. When troubleshooting with a child, there hardly ever any self-esteem problems to deal with. They feel valued just by the fact that an expert is willing to work with them.

3. Children are literal. When you ask a child what is showing on a screen, they will tell you exactly what is on there. If you ask a child if the screen says something specific, they will tell you just that and nothing more. If you ask a child what a cable looks like, they never say it's just a cable.

4. Children are open to being taught. This one is sort of a combination of the others, but I've worked with adults who showed the other traits and still failed in this one. The last thing most technicians want is a customer to keep calling back with the same problem when it is something easily fixed. Also, an educated customer is less likely to panic the next time something goes weird. Panicked customers are always difficult to troubleshoot with.

I could probably tack on that children tend to be more trusting of the technician, but that isn't necessarily why they are better at new technology. And for the record, I've dealt with senior citizens who show these traits and several of them have actually taught themselves to be technically savvy at ages that most people would not thought possible. Elderly women in particular seem good at this. I suspect it is because they don't have the preconceived idea that they have to be experts at it. So you can teach an old dog new tricks, but that can't beat old dogs who can teach themselves.

Interested in the research on Happiness?

I'm sure that like me, many people find the research on happiness fascinating. I've done a post or two (three?) related to it in the past. I was about to do another one dealing with the newer research when I realized I was actually recovering territory already covered better by another blogger - Sandy Gauntam, writer of The Mouse Trap. The blog is practically dedicated to the subject of happiness at the moment. She does cover other topics there, though, too.

Here are a few of her posts on happiness research:
Am happy, will be selfish; Am sad, will be fair. Oh Really?!?
Happiness opposed to despair/ennui; sadness to anger/irritability
Am Happy, will talk more and deep; am Sad, will make small talk
Am happy, will seek novelty; am sad, will stick with familiar
Why, Mr. Anderson, why, why do you persist?

Do I agree with all her conclusions? Of course not. I rarely, if ever, competely agree with someone's conclusions. I'm genetically onery and have a family tradition of being slightly rebellious to uphold. However, she does an excellent job presenting the research and to be honest, I haven't really made my mind up on the subject yet.

And for your additional perusal, more articles on the subject from other sites:

Using the Web in a right brain way



Pivot is a bit like how the right brain sorts and compares data, looking for patterns, anomalies and relationships. Like the right hemisphere, Pivot relies on global processing and dealing with generalities. I suspect as it becomes more used, Pivot will also specialize in finding patterns that can be described visually, but are difficult to describe in words. And like the right brain, Pivot arranges visual stimuli by appearance, using stored data to arrange parts.

Our right brains take simultaneous streams of information and created a master collage of that moment, using images, sounds, tastes, smells and feelings (both tactile and emotional). It manipulates those streams of information in ways not unlike Pivot's algorithms. What is amazing is that the right hemisphere is better at catching errors than the left. It is easier to prime, benefiting from even the weakest association. It is also easier to update with new information.

The "Dawn of Reason" gave humanity the opportunity to hone many left-brain dependent processes. I foresee this as the "Dawn of Global Analysis", which will hone many right-brain dependent functions in the decades and maybe centuries to come. I look forward to the other data analysis tools that will be spawned by this.

Visually thinking and different types of minds



Temple Grandin talks about thinking in pictures. I am so grateful that she has been able to find a way to verbalize how she visually processes things. There is no way I could possibly match her explanations. I straddle verbal and visual processing, but that doesn't mean that I totally understand a visual mind that doesn't has the access to the verbal skills I have. I know that I use visual processing. I also know that there I have not fully developed my visual processing ability. Verbally and mathematically, I had the training. I've been writing poetry since I was seven years old, thanks to my second grade teacher, who introduced poetry writing as part of an English/spelling lesson.

In this world of internet videos, I hope that more people like Temple Gardin are able to show us how to visually think - not only for those like me who intuit its power extends further than we see, but for everyone's benefit.

Visual Processing


I am a very visual person. I was raised by an artist and a computer programmer. This gave me access to artistic and flow-charting techniques. My dad used give my siblings and I flow chart templates to make art when we were young. When I became older, he explained what some of the shapes meant and then made a game for me. He'd give me a simple task and I would diagram the steps to do it, using those shapes properly.

As a family, we made almost weekly trips to the public library, bringing home art and music in addition to a multitude of books. Our home library sometimes had better references than my school's library. Arguments between myself and the sister just younger than me were usually solved by encyclopedias at ten paces. My mother made sure we had art classes. My dad made sure we had science lab kits. As a family, we made candles, leather and other crafts. Dad would also print out wall-size mazes which we kids and my mother would solved together. When I learned how to process information, it was not only through the verbal and mathematical means, but also visual and kinetic means.

I'm right handed, left eyed, and I have no dominant foot preference. I have taken math courses up to and including partial differential equations and I have about the same amount of credit hours in studio art as I do math. It probably follows without saying that my favorite math class was analytical geometry. I feel that this makes me qualified to make the follow statement:

Calculations can be done visually as well as mathematically.

Anecdotal evidence: When I was in high school, my mother took one of my classmates and I to an UIL science competition. Between the tests, the contestant schools could work on brain teasers. One of them was a word problem about how much material a sculptor would need if they made a bust twice as large in every dimension. While my extremely intelligent classmate began to do the mathematical calculations, my mother read the problem and immediately gave the correct answer. After verifying it with math, my shocked classmate asked my mother how she did the calculation. She used pictures and hand gestures to explain her thought process. He was totally lost by her explanation, so I gave him an interpretation he could understand. For the rest of the problems, my classmate and mother answered them with their own methods, while I translated between the two of them. In every case, both methods gave the same answers.

Historical evidence: All those wonderful geometry and trignometry relationships started out as a function of the relationships between visual elements such as lines, points, angles, planes and solids. M. C. Escher discovered several crystallography relationships years before the mathematical models, through purely graphical means. While many mathematicians hold Escher in the highest regard and consider him to have had an exceptional mathematical mind, he actually did very poorly with math in school and struggled to understand the mathematical treatises sent to him when he was older.

So, having made put that pet peeve to rest, I will share with you a diagram I made a few months ago showing visual processing as part of the problem solving process. While I do not detail how to do math visually (perhaps I will do that in another post), the diagram does show some of the ways visual processing has brought about solutions -> http://cosmicsiren.blogspot.com/p/diagram-of-visual-processing.html

Humor research

Very interesting article: The comedy circuit: When your brain gets the joke.

So what is a joke, exactly? Most theories agree that one condition is essential: there must be some kind of incongruity between two elements within the joke, which can be resolved in a playful or unexpected way.

It was interesting to find out that it is the way the brain solves the joke that predicts preferences. Especially to find out that resolvable jokes actually create more brain activity than the nonsense jokes many people try to pull off as being more sophisticated:

. . . When comparing MRI scans of people as they viewed both straight and nonsense humour, [Samson] found that straight humour evoked significantly more brain activity than a surreal joke in most volunteers. "Making sense out of opposed scripts and integrating this information seems to be a more complex process than simply laughing about nonsense," she says.

So much for sophistication in general. However, there was a subset of people whose brains did react more strongly to the surreal stuff - experience seekers "defined by a desire to pursue novel sensations, stimulation and experiences, whether it's through art, travel, music or an unconventional living style." It is this subset that probably gave rise to the idea that surreal humour is sophisticated humor. However, like most things, the generalization fails when applied rigorously. It's like saying "puns are the lowest form of humor". Some puns really are lame, but there are some very clever ones, which required a good degree of intellect to pick up on. In a way, punsters are like fighters: the crude ones are the least skilled, most obvious, and often miss their intended mark, while a great punster is like a ninja whose attack hits the victim's awareness moments after it has been delivered.

Another thing that dictates humor preferences is our degree to emphathize with others. Many jokes rely on the "Theory of Mind" - the ability to see something from another's point of view. These are the type of jokes that people with autism don't get. On the other hand, autistics love visual puns, which are more abstract.

Sidenote: While it takes longer for women to decide whether a joke's funny or not, they get a greater sense of reward from the limbic system.


What humor style do you have? is blog post about a study on types of humor. To summarize the summary, here is the stripped down list from Dr. Shock's blog:

Affiliative, use of humor to amuse others and facilitate relationships

Self enhancing, use of humor to cope with stress and maintain a humorous outlook during times of difficulty

Aggressive, use of sarcastic, manipulative, put-down, or disparaging humor

Self-defeating, use of humor for excessive self-disparagement, ingratiation, or defensive denial


Personally, I think most of us use all the types, but there is no denying that we tend to favor one over the other. Based on the feedback I get from people I interact with regularly, my preferred type is probably "self-enhancing". Or at least those are the jokes I am best at delivering. I often fall flat while delivering affiliative jokes and my memory suggests that I'm mediocre at delivering the aggressive or self-destructive jokes.

Art and Thinking

When I read some of the theories about how art began with humanity, I can't help but compare them to how drawing develops in children. There is such a strong connection between drawing development and cognitive development, as well as manual development, in children that it is hard to believe that "art" began as some dream state as some might claim. I'm not saying that it doesn't create an altered mental state, because it does. I'm just saying that art's beginning is entwined with the process of thought and the communication thereof. The existence of pictographs before writing also strongly points to a hand and hand relationship between art and communication. There is research that shows a connection between language and cognitative ability:

Neural correlates of Early Stone Age toolmaking: technology, language and cognition in human evolution.
Does Language Shape What We Think?

So it really shouldn't be that hard of a leap to connect drawing to the cognition process. Recently, I watched an older TED talk which showed this connection in a interesting way. I'll let Gever Tulley explain...



His observation that the act of decoration is part of the creative problem solving process, a method for letting the mind wander freely for a while, presents an possible insight into how our minds work. Tulley takes things a step further, introducing how manual development helps us mentally in this next talk.



I like the idea of his tinkering school. I like it even better that he can back his views up with anthropology and other science.

Brilliant!

Naming science as his chief inspiration, Mathieu Lehanneur shows a selection of his ingenious designs -- an interactive noise-neutralizing ball, an antibiotic course in one layered pill, asthma treatment that reminds kids to take it, a living air filter, a living-room fish farm and more.

And by science, he includes behavioral science too.

The Basis of Knowledge

David Deutsch starts out shaky in the talk, but stick with him. He hits his stride half-way through and then he is amazing.



Bad explanation: easy to vary

Good explanation: Hard to vary assertions, details have functional uses

Explanationless theories - bad science
