Description: There is an increasing large research literature on Sports Psychology in generally and on Olympic performance in particular. I have posted about parts of this research work previously in this blog ( The British Psychological Society has suggested in the posting linked below that it would be interesting to consider what the winter Olympics mean to us individually (that is also Psychology!). The Olympics are not regular occurrences. They twig thoughts of national identity and international connectedness and competitiveness. The Olympics present sports activities that could be considered a part of who we are (especially the Winter Olympics for Canadians). So, think for a minute…..What do the Winter Olympics mean to you? Once you have reflected on this question have a read through the postings linked below and see what else they may bring to mind.

For me the Winter Olympics are a place and time where Canadian athletes get to content at things that are very close to the Canadian heart ,… like hockey (even if the NHL kept their players playing here in North American instead of allowing them to go to Korea). I get to watch our athletes content on snow and ice, where, like it or not, we are at home for a (this year what feels like a LARGE) number of months. I most like seeing sports we do not typically get to see, like “big air” boarding and skiing, skeleton, luge and bobsledding and that weird event that involves skiing fast and shooting (OK maybe that is nor Nordic that Canadian). At the same time that I contemplate the parts of my identity as a Canadian that the Winter Olympics tweaks I am fascinated by the number of warm climate countries with representation at the Winter Games (Togo, Eritrea, and Nigeria, oh and Jamaica, of course). I have not reached any clear conclusions about what the Winter Olympics means to me in relation to my identity but, at least, they provide something entertaining and diversionary to watch and engage with as the cold winter February winds and snows blow.

Questions for Discussion:

  1. What are some ways in which large international sporting events like the Winter Olympics might increase or feed into our reflections about personal, cultural, and national identity?
  2. What is your favourite Winter Olympic sport? What do you think that might suggest about you?
  3. If the Olympics are in any way “good for us” (psychologically speaking) what might we do to optimize this “goodness”?

Description: As I contemplated whether to choose to blog on this particular topic I ran across the article linked below and while reading through it, for a number of associative reasons (I suspect), I was reminded of a song by Canadian Blues artist Lest Quitzau called Home on the Range. It contains the line “Welcome to America, ain’t it strange.” The song was on an album from back in 2001 but the line still reverberates today.  Specifically, what struck me as “strange” about America in relation to this blog topic is that America actually has a large enough sample of mass shootings in recent years (even on an annual basis) to ask the question implied by the title of the article. That question is something like, “what do mass shooters have in common?” The picture below is from the Las Vegas Mandalay Bay shootings last October and last night while at the Calgary Flames game against the Florida Panthers we were asked to stand a minute’s silence for those killed just north of where the Panthers play at Marjory Stoneman Douglas High School in Parkland, Florida. There is a LOT in this that is strange. It is strange that a common response to such events is to dig into the North American and particularly into the American focus on individual responsibility is all things to try and figure out both what was wrong with all those shooters and what could have been done to identify them and their future actions early enough to stop them. Unfortunately, this strategy runs up against the documented research fact that if the issue is one of mental instability or mental illness (just if) then it places the individuals of concern into a very small subgroup of all mentally unstable or mentally ill persons – those that may become violent and, further, it places them in the even smaller (microscopic) subgroup of mentally instable or mentally ill people who act in mass violent ways. It is strange that there is profound resistance towards the taking of steps toward gun control in America and that State legislative steps taken in Connecticut following the Sandy Hook Elementary School shootings in 2012 has only managed to track (and only slightly restrict) access to automatic weapons and to limit the size of the magazines in such weapon to 10 bullets.

So….. while it may not be something you feel comfortable doing (and if so them please do not do so and move on to another posting) but reflect for a moment on what you have heard seen and read about the large American mass shootings dataset (its constituent elements are intensely focused upon I the news media) and see if any candidate hypotheses come to mind that could be applied to the question of what mass shooters might or might not have in common. Once you have done that, have a read through the article linked below.

So, the explanation for mass shootings is NOT a clear mental illness. Shooters are often paranoid, resentful or narcissistic but typically NOT to the level of disorder and at least half have no clear evidence of mental illness before they start “crazy” shooting. As such, improved access to mental health care would likely not have resulted in therapeutic engagement for most shooters prior to their acting. A past involving exposure to or engagement in domestic violence may be a factor but certainly NOT a definitive one in that suspecting all involved in the perpetration of domestic violence of being potential mass shooters would result in exponentially more false positives than true positives (although engaging therapeutically with all who perpetrate or observe domestic violence would not be a bad idea). A sense of grievance and a desire for notoriety (particularly in adolescent and young adult shooters) are useful descriptors of mass shooter’s mental states but, again, taking social change or just pushes for social change personally would, like paranoia, resentfulness or narcissism, hardly get us focused closely enough on potential shooters in any way that would be preventatively useful. So what to do? It is not entirely and American problem. Canada had Marc Lepine at Montreal’s Ecole Polytechnique, but that was nearly 30 years ago and was only followed by enough subsequent shooters to fill an automobile as opposed to the 2 to 2.5 busses that could be filled with American mass shooters in the same time frame (and American numbers are increasing – see the figure above). The big difference between Canada and the United States? Well its NOT psychology, at least in relation to the shooters (Marc Lepine certainly had a sense of grievance), hmmm, maybe it is access to guns? Ain’t it strange?

Questions for Discussion:

  1. What psychological traits, issues, or illnesses may be involved in cases of mass shooters?
  2. Could any of the things you noted in response to the previous question be used to identify and stop or to at least warn more effectively about potential mass shooters?
  3. If gun control IS the best road to addressing the increasing rate of mass shooting in America what psychology will need to be brought to bear on the challenge such an approach would represent?

Description: When you read the words “retirement planning” what is the first thing that comes to mind? Well, probably money and pension (and even at an early age you SHOULD be thinking about this) but what else should folks be thinking about as they approach and enter their retirement? I have written in an earlier post to this blog about Ikigai (search it) and about other retirement considerations beyond finances. What do you think folks approaching retirement should be thinking about from a psychological point of view? Once you have a few hypotheses in mind read through the news article linked below and see if any of what it suggests was on your list. Research links to some non-financial retirement planning ideas are down at the bottom of this post if you want to see if your ideas have been studied.

So how did your hypotheses do?  Did you come up with one or two of the things that have been studied as part of retirement transition? Certainly, things like the changes in routine and the related shifts in day-to-day activities are important factors in retirement adjustment. The extent to which people’s identities are wrapped up in what they do occupationally can make for a huge post retirement transition. Bridge employment or encore careers are one way in which some people ease their retirement transitions. In previous postings to this site I have written about Developmental Life Design (mainly focusing upon how it applies to emerging adults) and much of what it involves could be a very useful part of peoples’ ongoing retirement planning. This, of course, brings us back to ikigai, the Japanese word on this topic referring to one’s search for inner meaning, self and purpose. Now THAT is a psychological concept worth exploring and what better time to do that but when you have more free time in your retirement! So, start preparing for this NOW by searching for the Developmental Life Design posts I put here at the beginning of this year (2018) and you will find what they suggest useful at ANY age.

Questions for Discussion:

  1. Beyond financial matters what else should we think about a plan for as we look ahead to retirement?
  2. When should you start to think about these things?
  3. What sorts of benefits might you accrue today by thinking about retirement planning using Life Design concepts and strategies (regardless of your age today)?

Description: Consider these questions. Is loneliness a problem for healthy human functioning and for basic health? If so, what is the current rate of (prevalence of) loneliness in the population? Does the rate of loneliness vary by age? Does it vary by other factors? What, if anything, should be do about this? From a psychological perspective should we look at loneliness as a symptom or as a causal factor? Once you have pondered these questions a bit a read through the article linked below which essentially asks how concerned we (as a society) should be about loneliness.

So did you notice the relative lack of psychology in the article? The article itself is more general, more sociological, and somewhat critical of how research is sourced and utilized in making arguments about things like loneliness. Essentially it tells us that claims about the prevalence of loneliness these days have been overstated and the rate of loneliness in the general population is about where it was back in the 1940’s.  This despite concerns over the potential levels of social isolation associated with the massive prevalence of the use of social media and other factors that reduce the level of genuine face-to-face interactions people typically have day-to-day and week-to-week. I suppose a more surprising finding might actually be that the rate of loneliness has not declined given that we can seek friends virtually through Facebook and other forms of social media. Be clear, loneliness IS associated with many challenging health issues including cancer, heart disease, and diabetes and with psychological issues like depression and anxiety. What we need to do is to not leap to conclusions about levels of social, isolation but, rather, to think carefully about what sorts of situations and circumstances give rise to loneliness and then think creatively about what we might do about it.

Questions for Discussion:

  1. How do today’s rates of loneliness in the general population compare to those in previous decades?
  2. How concerned should we be about the ubiquitous use of social media as a primary form of social “connection” these days?
  3. From a psychological perspective how concerned should we be about loneliness and what should we do about it?

Description: When individuals do horrible things we, of course, want to know why they did what they did. We want to know if there was something specifically wrong with them and, in particular, we want to know if there was either something that could or should have been done to prevent the person doing what they did or something that would have indicated their horrible potential and serve as some wort of warning. Forensic Psychology is a growing area of work and study that involves trying to figure some of this out. Forensic Neuropsychology is a newer and even faster growing area that looks to the brain for clues to help understand why people do criminal, dangerous, or horrible things. On Friday (February 9, 2018) a forensic neurology report was released that reported on a neuropathological (a brain autopsy) that had been conducted by Dr. Hannes Vogel, the director of neuropathology at Stanford University on the brain of Stephen Paddock, the gunman who killed 68 people in Las Vegas last October before killing himself. Think for a minute about what sorts of things such a forensic brain autopsy might be looking for that could potentially be correlated with the inexplicable behavior of opening fire from a hotel window into a crowd at a concert and then read the article linked below to see what the brain autopsy found.

Well, the title of the article gave the result, or rather the lack of a definitive result, away. At this point in our developing understanding of the brain we are looking in such autopsies for things like tumors or stroke damage that could have changed how the brain works perhaps by lowering inhibition or bumping up paranoia or both or something else.  The brain autopsy could not tell us about the possibility of manic depressive and or anxiety disorder that were suggested by a physician who treated the gunman up to about a year before he opened fire and, even so, those issues may be only vaguely correlated with the Paddocks decision to short at the concert crowd. None of that would have been useful in predicting or perhaps stopping the incident and focusing on those symptoms runs a larger risk of stigmatizing the huge number of people who deal with manic depressive or anxiety disorders without picking up a gun. The one possibly anomalous finding was a preponderance of corpora amylacea which are small spheres comprised of carbohydrates, proteins and other substances attached to a number of brain structures. The presence of corpora amylacea are related to age but also to Alzheimer’s. Their presence in high numbers as seen in Paddock’s brain could be an indication that “something is not right” according to scientists involved in research into corpora amylacea. What their presence in Paddock’s brain might mean is not at all clear, and, as always, more research is needed.

Questions for Discussion:

  1. What sorts of anomalies might a forensic post mortem study of a brain from a person like Stephen Paddock be looking for?
  2. What did the neuropathologist in this case conclude?
  3. What research might we do (or imagine doing) in order to better understand the role of corpora amylacea in human behavior in general and possibly in forensic neuropsychology in particular?

Description: Are you a courageous person? Do you know anyone who you would describe as courageous? Where do we need courage in our day-to-day lives? If courage is associated with dragon slaying and other sorts of battles, then perhaps we do not need it much these days. However, if courage is part of what it means or what it takes to take risks and to do things that we might find difficult then perhaps we need to be thinking a bit more about courage and about how to encourage its development in children and how to nurture it within ourselves. What do you think courage is related to? Is it part of personality? Is it in the genes? Is it related to the settings (family or organizational) in which we live and act? Once you have a few hypotheses in mind read the article linked below that describes three studies looking at these sorts of courage related questions.

So, it seems that courage is an internal quality of persons that can be nurtured in childhood by the sorts of things that support the development of “grit” and determination and self-confidence. It is also something that can be organizationally encouraged by organizations that are “flat” (power is not solely held by authorities of bosses and not used to keep people “in line.” Courage is also associated with age in the same way that wisdom is associated with age (you only get it as you get older) and it can be modelled. All things to think about, if we would like to be more courageous in our lives!

Questions for Discussion:

  1. What is courage?
  2. What is courage related to, psychologically speaking?
  3. What sorts of things can we do to help children develop courage or to develop it within ourselves?

Description: Alzheimer’s main impact is on peoples’ memories, right? Well, we can debate the depth of impact of the various features of the disease but it is the case that more than memory is affected. Specifically, the array of frontal lobe functions involving various aspects of what is called Executive Function (thinking, reflecting, planning and overseeing other activities and functions) are also negatively impacted by the creeping spread of Alzheimer’s disease. This means that many of the things people do that keep them functioning and independent are threatened (e.g., things like preparing meals and planning outings). Drug based therapies that have impacts on the memory related symptoms of Alzheimer’s may or may not impact executive function. So what else to do? Well how about if it were possible to use something similar to a pace-maker (an implanted device that stimulates and regulates heart function) in the frontal lobes rather than in the heart? Think about what that might involve and what it might produce in the way of changes in executive function and then read the article linked below to see what a study of a few case-study interventions with Alzheimer patients suggested. By the way, brain pacemakers have been used quite a bit with Parkinson’s patients.

So, while not a “cure” a brain pacemaker, like a heart pacemaker, may have a profound impact upon the disease course and the disease impact over time for potentially many Alzheimer’s patients and their families. Lots more needs to be examined but the prospects are quite interesting and intriguing.

Questions for Discussion:

  1. What is executive functioning?
  2. How is executive function affected in Alzheimer’s patients?
  3. What do brain pacemakers do and what, additional research should we consider doing in this area?

Description: As I write this it is Sunday February 5 and I am getting some work done to clear up my late afternoon and early evening so I can watch the Superbowl. I must admit to a bit of guilt over looking forward to the game as I have read a lot over the past few years about the level and extent of concussions in sports in general and in football in particular. While things are getting somewhat better (stricter adherence to concussion protocols etc.) there is no escaping the fact that football is a dangerous game as far as brain health is concerned. I can live with my guilt for now but with this topic on the back of my mind I was fascinated to run across an article describing recent research into a question that has tweaked my curiosity on more than one occasion but which I have not, until now, follow up on. The question was and is: Why aren’t woodpeckers constantly and horribly concussed? Ever have that question cross your mind? Well maybe it is just me….. but think about it a minute and then read the article linked below to see what research has to say about this question.

Ok so, first thing… it is true that woodpeckers have been around for millions of years and as such they must have evolved some things to allow them to cope with the g-forces involved in hammering wood with their beaks and heads over and over and over again… otherwise brain damage would be a strong negative selection factor related to that form of foraging. So we know now that the tau fibers that are associated with both concussion and early stages of Alzheimer’s in humans seem to play a strengthening and buffering role against brain damage if active (repeatedly head banging) woodpeckers. We also now that the construction of woodpecker skull and the cartridge that surrounds them provides very useful design ideas to people building things like bicycle helmets (more on this in the Further Reading section below). Now, short of replacing all football players with woodpeckers (and suffering the entertainment loss of all the very expensive Super Bowl Ads we will get to enjoy today, if they are not stripped by Canadian cable providers) There may be a lot more we can learn about concussion prevention and management from studying woodpeckers. Future research in this area is going to be interesting.

Questions for Discussion:

  1. Do woodpeckers suffer concussions?
  2. What roles to Tau fibers play in brain functioning?
  3. What sorts of research do you think we might want to consider supporting and undertaking in relation to woodpeckers and human concussion?

Description: One cannot open a paper or a magazine these days (especially in the weekend “lifestyle” editions) without encountering one or more article extolling the virtues of one diet or another for weight loss, health, wellness, vim vigor or longevity. Often such articles are rather light on systematic science or, if they cite studies they are a bit light on valid causal data. Basically, the challenge is that people who eat well likely also do many other things well (exercise etc.) and as a consequence it is not always clear whether their diets contribute substantially to they general mental, physical, or even sexual, wellbeing.  What kinds of data should we look for, before deciding if a newly developed or touted diet regime is worth seriously considering? The article linked below is a good example of this sort of research done right. The authors are NOT selling or “testing” their own proprietary diet plan (conflicts of interest do not support the validity of research). In addition, the diet they are examining already HAS a positive research track record. Finally, they conduct a focused longitudinal study that assesses “dosage” of the diet. Think about what such a well-designed study should look like then have a look at the article linked below. Oh, and the data is also informative about the impact of the diet on post-stroke dementia levels.

The key to the validity and causal-considerations usefulness of the linked study is the longitudinal nature of the study along with the dosage-level control — dosage meaning the comparisons of people who closely, not so closely and not at all followed the diet. Given the design features of the study, the results are worth paying attention to.

Questions for Discussion:

  1. What is the diet that was looked at in the study?
  2. How does the diet looked at in this study relate to brain health?
  3. What are the important design features that make this a study particularly worth paying attention to and how might you briefly articulate this as part of an article in a newspaper or magazine about this study?
