Description: What does it mean to say that some human trait or behavior is partially genetically linked? Does saying that change or influence how we think about the trait? Looked at another way what would the socio-cultural (and perhaps political) implications be of a trait or behavioral tendency being partially genetically linked? Would your answers to these questions vary if the trait in question was color blindness? How about intelligence? How about sexual orientation (defined in a simplistic and limited way as ‘ever having engaged in sex with someone of the same sex)? The problem is that our thinking about these sorts of questions often boils down to thinking in terms of simple, single gene, inheritance situations, like red-green color blindness and our thinking about the other implied side of these questions – that if a trait is not ‘caused’ genetically (due to nature) then it is caused by the environment and/or by choice of some sort, potentially. In the socio-cultural politics of gender identity and sexual orientation one wonders if there is anything at all to be gained by asking nature/nurture questions. The authors of the research paper described in the article linked below and the journal that published the research article itself pondered these questions and then decided to go ahead and publish the research. From a Psychology perspective I do not have a strong view of this but from larger social perspective I believe there are a number of things to be pondered in relation to this research. Gather your own thoughts on these matters together and then read the article linked below and see where it takes you in your thinking.

So, we cannot predict sexual orientation (as simplistically defined in the research discussed) for people’s genetic profiles which account for 8 to 25% of the prediction variability and no one gene accounts for more that 1% of the variability of prediction. Also, there were issues with the dataset used in the study, as large as it was, which included that it was mainly white, limited in sexual orientations identified and in how the question of sexual orientation was operationalized based on the data they had in hand. The last word on this, for now, belongs to the author of the research paper itself:  “Our findings provide insights into the biological underpinnings of same-sex sexual behavior but also underscore the importance of resisting simplistic conclusions, because the behavioral phenotypes are complex, because our genetic insights are rudimentary, and because there is a long history of misusing genetic results for social purposes.”

Questions for Discussion:

  1. What did the research discussed in the article linked above have to say about the relationship between genes (nature) and environment (nurture) on sexual orientation?
  2. What should the next research steps in this area involve?
  3. What are the socio-cultural (political) implications of this sort of research and of this study in particular?

Description: You have certainly heard about people described as anti-vaxers, people wo do not want their children vaccinated against diseases link the measles, mumps and rhubella because they believe there is scientific evidence that immunizations cause autism (despite the fact that the evidence is conclusive that there is no such effect and that the dangers of exposure to diseases that have been close to controlled by vaccination high). Well put that aside for now and consider something g you may not be as aware of – fluoridation. Fluoride is present naturally in some water supplies and it was discovered than when it was present, children who drank the water had far fewer cavities than did children who drank un-fluoridated water. After much research which confirmed the dental health advantages of fluoride and showed no consistent detrimental effects many municipalities added fluoride to their drinking water. And what was the public’s reaction to this? Well, the vast majority enjoyed fewer child cavities and otherwise did not give it a second thought. For some, however, like anti-vaxers, this was a dangerous threat that needed to be stopped. So, recently, years later, a study is published in the Journal of the American Medical Asosiciation (that means BIG deal research) which reported that prenatal exposure to fluoride may (or may not, depending on how you measure it) lead to lower preschool IQ scores. What should we do? Well if you are one who has always worried about fluoride then you may not need to read the article to decide that it suggests that “claims that thousands of studies show fluoridation is safe are not true. In fact, public health has been negligent about examining the health of people living in fluoridated communities.” One study! Well you can stop reading now or you can decide that, in the words of Seth Meyers “Its time for a closer look.”  If, like me, you put at least as much (actually a little more) faith in the scientific perspectives of late night talk show hosts as you do in those of anti-vaxers and anti-fluoridationists then have a read through the article linked below which provide a VERY useful critical review.

Ok, so what do you think about fluoridation now? Something that is, hopefully, part of any introductory psychology course section on research methodology is the notion that studie4s need to be well designed, that causal statements need to be made carefully and sparingly and that the findings of single studies are rarely, if ever, definitive enough to support suggestions regarding public (health) policy. If and when you see studies like this one written about in the news media or waved about by special interest groups, I hope you read them as carefully and as critically as the author of the above linked article did. Oh, and, IQ tests of 4-year-olds do not typically produce stable results.

Questions for Discussion:

  1. Based on the research article discussed in the linked article does fluoride effect intelligence?
  2. What are some of the issues relating to the discussed research that could (should) limit the interpretive weight we place on it?
  3. If someone was reading the research article discussed above and was not aware of any of the other research on fluoridation what advice would you give them?

Description: It is frankly quite alarming how many times the opportunity to have this sort of conversation arises these days. Someone goes on a shooting rampage and we and the media try and figure out why. As a psychologist, I am most concerned that it is too easy for people to say some version of “that person must have been crazy.” Too easy because it diverts out thoughts and attention from the realities of such situations. In a sort of “just world” biased way we say that mass murderers must be crazy, and this means that there is nothing in the sane, rational, world that we can do about such events. Or it turns the lens toward Psychology and Psychiatry suggesting that we need to get our act together to better predict which crazy people are most likely to take up arms. Well, one way to push back on a Just World bias is to suggest that there is no Just World there is Just Us. Have a look through the article linked below for a reasoned, evidence-based overview of the nature of Mass Murders, mental illness and what sets them off (and what doesn’t).

It is important that we look at the data and that we carefully consider what others are offering as explanations of, or as ways of ducking dealing with the conditions that give rise to, the heartbreaking number of mass shootings across the world in recent years. The often ignored fact is that mass murders are no more crazy that the rest of us and that evidence-based statement should bring us back to a focus on the factors that actually ARE causally at play.  As the author of the article puts it “The scary truth is that ordinary human hatred and aggression are far more dangerous than any psychiatric illness. Just think of the many people driven to mass murder because they were fired by employers or dumped by girlfriends. In all likelihood, they were not mentally ill but simply full of rage — and well-armed.” Psychology has a LOT to say that can be helpful – about what is NOT involved and about how our self-serving and self-defensive biases sometime keep us from looking seriously at what it at play – in relation to mass shootings. (the comments linked at the bottom of the article are fascinating too).

Questions for Discussion:

  1. Does it make sense (scientifically) to say that mass murders, in general, are mentally ill?
  2. Is the Diagnostic and Statistical Manual problematically limited in relation to mass murderers and what drives them?
  3. Where might psychology (research, theory and practice) be of assistance in efforts to reduce or eliminate mass shootings and mass murders?

Description: What was the name of your best friend in grade 1? What did you have for lunch the day before yesterday? We most often find that the older memory is still there but the more recent one is not, or is, at least, harder to recover. I have no doubt that you could come up with a subjective theory for why that works. You spent a LOT of time with your best friend, used their name a LOT and so that memory is stringer than the one related to whatever you had for lunch recently. However, what sort of theory/hypothesis would you come up with if you were asked to speculate as to how that memory effects plays out in your brain? What happens at the neuron level to make old memories sometime so much stronger than new memories? Oh, and while you are at it, think about how you would design an experiment with mice to test your hypothesis (so you can monitor their neuronal functioning closely and take advantage of the fact the 30 days is a LONG time in mouse years. Once you have your hypothesis and methods sorted out have a look through the article linked below that describes the work of one lab looking at these questions.

So, no surprises? Well of course not, we can look back to one of the earliest theories of memory, the engram theory, that suggested that memories are made up of neural circuits in the brain, except that when Carl Lashley went looking for them in the brains of rats he had taught to run a maze (had  them develop a memory circuit for the maze) he could not find them – the removal of no brain areas resulted in the rats forgetting the maze. What the research discussed in the article linked above suggests is that learning the maze when motivated by the resulting food reward lead to the rats consolidating their memory by mapping it over a large number of neurons making it harder to remove or for time to extinguish.

Questions for Discussion:

  1. Are the effects discussed in the article simply due to rote memorization?
  2. How do the researchers explain how the consolidation of robust long-term memories might be understood and does that make sense to you as a description of how neurons work?
  3. What, if any, are the implications of this line of research for the effects of aging on memory?

Description: The internet provides us with access to vast arrays of information and research. Given this shouldn’t our beliefs be much more research based than they used to be? Weeelll, what about anti-vaxers? What about climate change deniers? Think about what the access to information provided by search engines like Google might do for us or to us especially when we are searching for information about things that we are afraid of? You have likely heard about confirmation bias, the notion that we are more likely to “see” or “hear” things on-line that confirm our existing beliefs and to not “see” or “hear” things on-line that challenge our current beliefs. Think about why that might be AND then think about how we might present information to people in ways that will move their beliefs in ways that better fit accepted scientific findings?

So, we generally act on our beliefs rather than acting on the basis of the weight of scientific research finding in related areas. While being interesting and somewhat alarming, when we consider things like vaccination and climate change, it becomes more important that we not only understand the impact of false beliefs and fake news but that we figure out how to overcome its impact of public health and the very survival of the planet. Important things to think about AND then act upon!

Questions for Discussion:

  1. Why might searching on-line for information about something we are afraid of lead to or support false beliefs?
  2. Why might fake news and false beliefs matter in relation to population health?
  3. Is there an “ethics” of false beliefs and fake news and if so who is responsible for understanding what it involves and for generating policies for moving it forward?

Description: You have very likely heard about grit? Grit is perseverance and a tendency to push on through adversity rather than simply giving up. Grit is often presented as something we should all get more of, but other than being told to get more we are not told how to go about doing that. The impression is that grit is something like a general trait that some people have more or less of than others. To be fair, Angela Duckworth, who initiated our recent research interest in grit does suggest that we can add to our grit profile but a broader understanding of grit and what it is related to (and different from) would be very helpful. So, is grist a general trait? What else is grit associated with and what of grit and these related things can we work on? Think about your own hypotheses in relation to these questions and then read the article liked below to find out what a recent Canadian study has to say on these related matters.

The distinction between traits and states can be an important one for many reasons but quite important is the impact of our understandings of and beliefs about traits and states. Generally, we see states as transient and more open to influence than are traits which are seen as more constitutive of who we are and less open to change. This sort of dichotomous thinking is, on its own, sometime problematic. In terms of grit the research discussed in the linked article represents a first step towards unpacking how grit plays out in our lives and that could potentially be very helpful for both our understanding of the nature of grit and for developing action plans to change what we can for the better in the various areas related to grit. So, grit is more specific than general, and it is related to issues of maladaptive perfectionism. As well the idea that a growth mindset is significantly more adaptive than focusing on finding and pursuing as passion is potentially quite helpful as well. The bits of this study start to show us the potential advantages of broadening our understanding of concepts like grit and how they do or could play out in our lives. An important new line of research for sure. Oh, and here is a useful term: wabi-sabi, which is a Japanese term for accepting transience and imperfection (think about how that might relate to ikigai).

Questions for Discussion:

  1. Is grit a state or trait or is this not the right sort of question to ask?
  2. What is maladaptive perfectionism and what sorts of things does it impact?
  3. How might we understand the interplay of grit, maladaptive perfectionism and growth mindset?

Description: Perhaps you have heard about the use of ECT (electroconvulsive shock therapy) to treat “treatment resistant depression. It involved(s) the induction of a grand mal seizure (random firing of all neurons in the brain) through the application of electrical stimulation of the brain. Why does it work (when it does)? It seems to “rest” the neural systems in the brain. Taking the notion of a neural reset further is the experimental treatment for anxiety and depression described by Heather Armstrong, a woman who went through the treatment, in the excerpt from a radio interview linked below. A few details of the treatment are covered in the interview (more in the references section below) but most striking is Heather’s vivid description of what it was like to awaken from the treatment and in particular after her fifth treatment. One of the huge benefits of case studies (despite the limits to their generalizability) are the rich insights they can provide into the subjective experience of disorders such as depression and of the subjective impact of treatments that seem to work.

The induction of a comatose state using an anesthetic called propofol is thought to act on symptoms of anxiety and depression by resetting or reawakening the brain’s inhibitory systems. Heather’s description of it as “something marvelous” is quite striking. Of course more research is needed but the early returns on this experimental treatment seem quite promising.

Questions for Discussion:

  1. What do ECT and propofol do when used as a treatment for “drug treatment resistant” depression?
  2. Is the phrase “neural reset” simply a literary shorthand or is it a useful description for the treatment described in the interview/story linked above?
  3. What sorts of research are needed going forward if we are to both understand and properly regulate this form of treatment for anxiety and depression?

Description: What causes schizophrenia? If you said something like “a chemical imbalance in the brain” you are not alone and that fits with what else you likely know which is that there are a wide array of drugs available that are used as parts of efforts to address that “imbalance.” However, you know those drugs are NOT a cure, don’t you? SO back to the original question: What causes schizophrenia? Is there a genetic basis for the disorder and what would that mean as genes are fixed but schizophrenia emerges in adolescence or later? So, what do we need in order to answer the question? Well maybe, epigenetics, which is the study of the changes in brains and elsewhere that are caused by modifications of gene expression as opposed to the structure of the basic genetic code. How does that work and how might it help us to begin to understand the causes of schizophrenia (and/or bipolar disorder)? Well have a read through the article link below to get at least a glimpse of the possibilities.

So, most of the antipsychotic drugs in use today work in one way or another by reducing the storm of dopamine that is related to the symptoms of schizophrenia. But that is only half of the story. The other part involves a scrambling of the neural synapses responsible for the “rapid-fire neural impulses responsible for healthy function.” This second process may emerge epigenetically earlier (that the dopamine flood). If so, then if it become possible to find markers of these shifts then earlier identification of the epigenetic pathways that may be heading towards schizophrenia and THAT may lead to earlier, more effective interventions on our way to actually figuring out the causes of schizophrenia and bipolar disorder. Exciting stuff!

Questions for Discussion:

  1. What do we mean when we say that schizophrenia and bipolar disorders are the results of chemical imbalances in the brain?
  2. What does the epigenetic study and analysis discussed in the linked article suggest about the possible causes of schizophrenia?
  3. Where does this line of research take us in relation to causes and/or cures for schizophrenia?

Description: How do you feel about personality tests? If your response to this question is some version of “meh” you might want to reconsider. Aside from being a part of all introductory psychology course curricula many people view personality tests as those diversions they encounter in magazines (well, on line these days). However, it is worth considering the full extent of the industry of personality testing. Outside of the frivolous use noted above think about where and how personality tests are used. Think hard because I guarantee you that you have not thought of the full extent of their use and of the potential impacts their use have upon us. Ready for a deeper look? Ok, have a read through the article liked below that provides a brief historical overview of the uses of personality tests and provides a broader context for understanding their current (and increasing) use.

So how does the historical perspective, provided in the linked article and its linking personality testing to recent heavy concerns about the privacy of our personal data, affect your thoughts and feelings about personality tests? While individual difference psychology, where personality tests (and many other tests) come from, is typically depicted as a pragmatic sub-discipline focused upon the nuts, bolts, and minutia of measuring human characteristics, attitudes, values etc. the linked article points to a  number are areas which may suggest to you a need to open a lie of ethical consideration of personality testing. Such possible questions will be of increasing importance as we move forward into a worlds (lives) of bigger and bigger data.

Questions for Discussion:

  1. What are personality tests supposed to do (to measure)?
  2. How are personality tests used by organizations and by marketers?
  3. What questions do you NOW feel like we should be starting to ask about personality tests?

Description: There has been a lot of research and debate lately about the developmental impact of social media and smartphones. That debate IS important, but it is worth revisiting an issue that, while not that old, is not a particularly salient part of our conversations about development and particularly about risk management. Most jurisdictions have enacted some form of distracted driving legislation intended to limit a range of driver distractions including cell phone use, while driving. If you are a driver, even a newly licensed driver, I am sure you know you need to be careful about how you use your cellphone while driving (handsfree is permissible in many jurisdictions) and you also know that you should not text while driving. So, no problem, right? Well how about this finding? In 2015 27% of teenaged Ontario (Canada) drivers admitted to texting while driving and 3 years later the percentage had dropped to 6%. Fantastic, this reflects a huge positive change in risk related behavior, right? Well, what if the young drivers in question have NOT reduced their frequency of texting while driving but have, rather, realized that had better not admit that they are doing so? Everyone could use a research-based reality check regarding driving and distraction (and not just involving cell phones). So, think for a minute about how well you manage your limited attentional resources while driving and think about what a list of possible distractors while driving might include and then read the article linked below for your own driving reality audit.

So how did your driving distraction audit go? One of the largest challenges to effectively managing distraction risk while driving is the distance (or time) one typically drives between driving events that are seriously hazardous. This is a perfect circumstance for growing an illusion of control and for lowering one’s concern about distracting actions, thoughts and strategies. It is a VERY good idea to take stock from time to time of how well you are actually managing your precious limited attentional resources while driving! It is also worth noting that we cannot always trust that our research participants are fully disclosing the behaviors we are asking them about.

Questions for Discussion:

  1. What sorts of (categories of) things contribute to driver distraction?
  2. What research methodologies are needed if we want to get a clear picture of what drivers are really doing behind the wheel?
  3. What are some things we could do to better prepare new drivers to properly and reflectively manage their attentional risks and hazard exposures while driving?
