Description:

Marijuana is going to become legal in Canada in a few days (October 17, 2018). Here is a timley question. What do you know about the affects of marijuana on human behavior and performance? Well, linked below is a review article from the journal Forensic Science with that exact title and it contains, I would bet, more information that you feel you need to know about issues of impairment, testing, medicinal uses and much more related to Cannabis (Marijuana). While you may not wish to read the whole article I would suggest that you take a few moments and think about what you do and do not know about the affects of marijuana on driving and on flying (among pilots, not metaphorically or poetically speaking) and then download the article and at least read through the section on impairment starting on page 33 and see how what you know or think you know about that topic relates to what there is to know.

So, how did what you knew or thought you knew about the impact of marijuana on human performance stack up against the data summarized in the review article? The research reviewed in the article clearly indicates that there are problems with toking and driving world-wide. What is also clear that it is difficult to figure out just how we should define and assess that impairment for regulatory (enforcement) purposes. But, while that work is still ongoing a simple message is already clear in the research done to date. Don’t toke and drive (or fly)!

Questions for Discussion:

  1. What are the three ways in which the questions of the impact of alcohol and/ or marijuana on human functioning have been addressed in research?
  2. Of the three ways in which these questions have been looked at which one did you find the most compelling (or interesting)?
  3. What additional research do we need to do to get the questions in this area sorted out?

Description: With marijuana becoming legal in Canada this week (on Wednesday Oct 17, 2018) a wide array of questions (not many of them actually very new) are being asked about the effects of marijuana on human functioning and human health. If you have been in Canada you have probably seen some of the ads advising people not to “toke and drive” and while this is not a new issue, the legalization of marijuana raises the profile and perhaps adds some urgency to the question of how “impairment” due to marijuana should be define, quantified and enforced. Police have the ability to take action if a driver seems impaired for any reason (drugs, alcohol, sleep deprivation, prescription drug side effects, mental illness etc. One of the links below describes the Standard Field Sobriety Test which looks for indicators that a driver should NOT be driving. Breathalyzer testing followed by blood tests are used to determine blood alcohol levels for which there are legally defined numbers that indicate chargeable levels (.08) of alcohol in the blood and while there ARE individual differences in how people respond to that level of alcohol in their blood the law is clear and the data on the impacts of alcohol on driver performance are also fairly clear. Things are far from clear in relation to marijuana and driving. Some people claim if does not affect their driving while some even say it improves their driving. There IS a recently announced test of blood THC levels that involves roadside testing of a saliva sample but there are concerns about the reliability of the testing units (not the least of which, for Canada, that they do not work well when they are cold) and it is not clear what blood levels of TCH should be set as the legal limits for impairment. So, think a bit about what research you would want to see or to do in order to hopefully move to a defensible standard for determining if or when a driver is legally impaired by marijuana and read through the articles linked below and see if they clarify things for you.

So, were all of your questions answered? Were any of your questions answered? Police have always had the ability to determine if, in their informed opinion using roadside sobriety testing, they should allow a driver to stay on the road. However, there are a lot of questions still about how we might define, and measure impairment based on marijuana use. With the legalization of marijuana in Canada we have an increasing need to do the research necessary to get us closer to answers to the questions of how we define and assess marijuana impairment.

Questions for Discussion:

  1. How should we define impairment by marijuana in relation to operating motor vehicles?
  2. How might we answer the question above in   relation to workplace related issues of risk and liability?
  3. What are some of the issues that potentially make these question more complicated in relation to marijuana than they have been in relation to alcohol?

Description: This next Wednesday the use of cannabis or marijuana will become legal in Canada. If you live in Canada you cannot have missed the torrent of media on things like the formation and marketing of companies to produce, market and sell marijuana or the public service ads pointing out that toking/ingesting and driving are illegal and dangerous (we are even seeing some of the old style drink-driving tv adds showing people having fun and then having a collision as a result of toking/ingesting and driving.  As a way of marking this large-scale change in legal restrictions I thought I would post this week on research and media articles talking about research relating to the effects of marijuana on human psychology and behaviour. One big change in moving marijuana into the “legal but with limitations” category along with alcohol is the imposition of an age restriction. Prior to legalization, as long as people were prepared to ignore the illegality of using marijuana there were no hard and fast age restrictions on its use. Now that you need to be 19 or over in every province in Canada except Quebec and Alberta where, like alcohol the age will be 18, to legally use marijuana the question of the impacts of marijuana use on “minors” become a more defined concern. So, what do you think? Are there negative effects on teenagers who use marijuana compared to its use by older individuals? Think about it and then read the article linked below that talks about a recently published study looking at this precise question.

The Canadian study discussed in the article linked above indicated that their results suggest that marijuana use in the teenage years may negatively impact cognitive or thinking skills, memory and behavior and may do so to greater extent than drinking alcohol. The researchers point to a larger amount of work that has clearly shown that the frontal lobes of the brain are still developing throughout AND beyond the teenage years and are involved in important executive functions like working memory, impulse control, risk management, and general planning. One of the most important aspects of this study is that it takes a developmental perspective. This means that it will contribute to our ability to understand how cannabis use might have particularly important impacts on the still growing and developing brains of teenagers and, if so, would provide strong support for maintaining and perhaps even considering adjustment to the age at which the use of marijuana becomes legal in Canada.

Questions for Discussion:

  1. How was it that 18 or 19 was picked as the age at which substances like alcohol and, now marijuana become legal?
  2. What sorts of research should, and perhaps now with legalization, can we do that looks at the impacts of marijuana use on human brains, minds and bodies?
  3. Why is it important, in designing research to look at these sorts of questions, to make sure to include some work from a developmental perspective?

Description: I have posted a number of times in the past on the topic of PTSD (Post Traumatic Stress Disorder – search PTSD in the Weekly Updates search window). Symptoms of PTSD are worryingly common among retiring military veterans. The rate in the general population is just under 10% while the rate among returning vets is in the neighbourhood of 35 to 40%. A variety of approaches to support and to treatment seem to possibly help — look at the results of the search I recommended above, and you will see references to animal assisted therapy, support animals, EMDR (look it up), and general cognitive behavioral therapy. In addition, medical marijuana has shown some possible positive effects though the Canadian ministry of Veterans affairs recently seriously cut their budget for medical marijuana for vets citing exponential cost increases and the lack of sufficient numbers of vets in Canada to support a properly controlled study of the effects of medical marijuana on the symptoms of PTSD (sound fair?). So, what might research tell us about the possible positive impact of otherwise illicit drugs (and yes marijuana WILL soon NOT be illicit in Canada, but it will still not be free for those that potentially need rather than want it) on the symptoms of PTSD and as an add-in the psychotherapy? Well the article liked below talks about a research study recently published that looked at the effects of different levels of MDMA (yes ecstasy, like what was given to an octopus in the posting I put up last week). Before you read the article think about how you would design a study looking at the effects of MDMA as an adjunct to psychotherapy with people suffering symptoms of PTSD. Would you want the participants to know if they had been given MDMA? Would you vary the dosage? How would you fold the drug and therapy together? Once you have thought about these design issues have a read through the article linked below to see what the researchers did.

So, did the double-blind design seem to work? Why try for a double-blind design? Why might it have not worked at all dosage levels? If the results are replicable these results could suggest a powerful approach top therapy for veterans with PTSD. It is worth thinking about what sorts of ethical concerns we might have to address before moving forward with such an approach to treatment (assuming it works). I hesitate to suggest that, if the data bears this approach to treatment out perhaps the relative cost of marijuana and MDMA might also be a consideration in deciding how to proceed.

Questions for Discussion:

  1. What is it about MDMA that might support therapy effectiveness for those with PTSD?
  2. What sorts of research is still needed before this approach the treatment of PTSD get green-lighted?
  3. Are there other disorders or populations that might be considered for similar exploratory treatment research?

Description: What is Behavioral Economics? Well it is the area (of Economics) in which a Psychologist, Daniel Kahneman, won a Nobel prize in 2002 for his work (in Psychology) on how human beings make decisions about money and about other things. It is the area of study that looks at the ways in which we (irrationally) make decisions. Think about this question. Which of the following would you feel more strongly about… losing $5 OR winning $5? Behavioral Economics research has suggested that we are more “loss averse” and as such would feel more strongly about losing $5 than we would about winning $5. This is supposed to be (again according to Behavioral Economics) why we can be “nudged” to do more healthy things by being told what we will lose if we don’t and to contribute regularly to a retirement savings plan by being told what we would lose in the way of comfort and security of we do not. So is lose aversion a broadband explanation for a lot of our behavior? Well, think about this “what if”. What if someone gave you a mug (nothing fancy, just a coffee mug). What price would you set the mug at if it were suggested that you try and sell it? What if you did not get a mug? What price would you pay for a mug being offered for sale. Well when social psychologists asked people these questions the results were straightforward. People would sell their mugs for and average of $7 but if they did not have one they would agree to buy one for $3 on average. Why? Perhaps because those with mugs were more averse to losing them that those who did not have a mug thought they would be happier if they bought one – so loss aversion, right? Well think about it. Can you come up with another explanation? Once you have thought about it have a look at the article linked below and see what the author, a social psychologist thought and what he did to test his alternative hypothesis.

So, what do you think of Dr. Gall’s inertia hypothesis? He is a professor of marketing and so is particularly interested in the application of behavioral economics to marketing campaigns. The loss aversion hypothesis has led a LOT of marketing groups to develop sales campaigns for their products or services that try and focus potential buyers on what they will lose if they do not make use of the proffered product or service. The problem is that a large meta-analytic study found that there was NO statistical advantage to public health campaigns structured around loss aversion – no positive behavior changes. So, here is a challenge for Behavioral Economists (or for Psychologists working on Behavioral Economics questions from a Psychological perspective in search of another Nobel prize). When IS loss aversion at play, when is it NOT at play and what are the situational effects that drive those differences? The marketers and public health advocates of the world are waiting for and need answers to these questions!

Questions for Discussion:

  1. What is loss aversion? Provide a couple of examples.
  2. What sorts of areas might rely on research done within Behavioral Economics (done by Psychologist or others)?
  3. What alternative explanation was offered to loss aversion in the article linked above? What does the alternative explanation suggest we should do with the notion of loss aversion?

Description: Think back (perhaps back to your grade school days) and think of a time or situation where you got left out by your peers, where you did not get invited to a birthday party or asked to play in a recess game. How did that make you feel?  Does that sort of thing not happen as much to you now? Well, what about your social media connections? Do you get left out there from time to time? We are a social species and as such we are quite sensitive to noting situations that involve social exclusion and social networks may actually provide more opportunities for social exclusion than old school face-to-face social interaction. So, think about your social networking activities and think about the amount of social exclusion anxiety you encounter on a week to week basis. Also think a bit about what we might do to get people to increase the number of things they do socially on social media networks that could increase rather than decrease social inclusion. After that bit of thinking read through the article linked below to see how the social psychologist author of the article designed studies to look at these questions.

If you think about it you can see that while social media makes it possible to connect in some ways with many people at a distance such connections also tend to shift you out of the moment or, more specifically, out of the here and now. If connecting socially in the her and now is what we evolved to view as base social connectedness, then perhaps being more mindful would reduce social exclusion and increase social kindness. That is what the author of the article linked about found in his research. People who completed a mindfulness exercise prior to engaging with others over social media di show more kindness and social inclusiveness. Perhaps mindfulness checks are things we could engage in that would make us more “real” by face-to-face social interaction standards and move us towards being more positively social inclusive in our interactions.

Questions for Discussion:

  1. What is social exclusion and how does it arise in social media-based interactions?
  2. How are social inclusion and kindness related?
  3. What sorts of things should we think about or engage in if we want to ensure that our social interactions over social media do not include a problematic level of social exclusion?

Description: As a Psychologist I have to say that events south of our border over the past two years have a source of fascination, confusion and perplexity not to mention anxiety, fear and anger and that is just from considering the actions of the current president. This past week the confirmation hearings focusing on Brett Kavanaugh’s possible appointment to the American Supreme Court opened up a whole new universe of areas and issues for psychological contemplation. Rather than trying to focus too directly on any one area or issue (given the unfolding nature of this array of issues) I though I would just list a number of questions of psychological relevance that have arisen in the media and based on my own reflection on these recent noxious events. In each case I will point you to an article and/or two, but more information will likely emerge as the events and our reflection upon them unfold. As well, you can dig into the relevant psychological research literatures to see what research has been done in these areas. So, here are some questions arising from the American Senate hearings and from the contexts surrounding those events.

In her testimony before the Senate Committee, Christine Blasey Ford said she could recall every detail of Brett Kavanaugh’s alleged attack on her when she was 15 years old but had difficulty recalling related event details. Does this fit with what we know about memory for traumatic events decades past? The research says yes, see link 4 below.

How DO trauma and the passage of time affect our memories for the events they involve? Answers to this question can get complicated. See link number 3 below.

Does asking women to describe and discuss the impacts that alleged sexual assaults had on them have an impact on the likelihood that they will report such events in the first place? The answer to this question seems to be yes. See link 1 below.

Does the storm of media information and coverage of issues related to trauma and sexual assault have an impact upon those who have suffered such events? The answer to this question is most certainly, yes. The news is loaded with triggers for victims of sexual assault and related traumas. See link 2 below.

These events are occurring at an important time in the history of societal views and thinking about issues associated with sexual assault and gender-based issues. The #metoo movement has started to shine strong lights on issues of male and power privilege and on the fundamental imbalance between “innocent until proven guilty” and the huge burdens of proof placed on victims before they are believed. We do not just need more research in these areas we need more thought and more action.

Questions for Discussion:

  1. What are some of the psychological issues arising from, or brought out by, media coverage of the Kavanaugh Senate hearings in the United States?
  2. Can you think of any new areas where psychological research is needed? Are there any areas where it may be that some assumptions underlying past research or at least past research questions might need to be revisited?
  3. What approach (research, investigative, etc.) would be preferable in situations like this if senators were interested in understanding and properly addressing the sexual assault allegations in the Kavanaugh confirmation hearings?

Description: Quick! Answer this question off the top of your head: Is texting good or bad? Well, assuming your mind did not leap to issues arising from presidential tweets your yes or no answer likely reflected your personal preferences regarding texts or perhaps the Psychological researcher in you suggested that the question was too simplistic and uncontextualized to be addressable. So, here is a potentially better question: If you were designing a program of research looking at texting patterns, habits and (psychological) consequences what sorts of things do you think need to be examined and how should they be examined? Once you have given that a bit of thought read through the article, written by someone who has actually done research on texting, and see what she, and others, have done and see how it aligns with your possible research direction thoughts.

While there has been a lot of doom and gloom speculation about the developmental and social impacts of texting and social media in general I, at least, am pleased to see that research is being done that does not begin with a dismissive or terrified stance on these new forms of social interaction. Texting is not going away and Psychology needs to help us to understand how it works and how it differentially impacts or is differentially taken up by its diverse array of users. The research discussed in the article linked above provides data-supported dimensions along which text-users seem to vary. Such work is critical to understanding both the core issues associated with new communication mediums as well as the dimensions along which individual users vary. Work like this and the work of the author of the article will help us to build an understanding of how texting is being taken up by users (or not) and will also help us to see or even to anticipate areas where new or unexpected issues or problems may arose for people using new modes of communication.

Questions for Discussion:

  1. What issues do you have or potential issues, from a Psychological perspective, do you have or see with texting?
  2. Do you see any potential developmental issues associated with texting (due to its age-related variability of use)?
  3. What are some other areas or aspects of texting or the texting experience that Psychological researchers should be looking at, in your view?

Description: If you have spent more than one or two days in a workplace setting you have probably heard of and even completed the Myers-Briggs Type Inventory (MBTI). The MBTI is a personality inventory that, based on your responses, places you somewhere on each of 4 dimensions including Intuitive/Sensing, Introversion/Extroversion, Feeling/Thinking, Perceiving/Judging. If you took the test in a workplace setting think back to what you were told was the purpose of the assessment and about what it was suggested would be the potential uses to which you could put your results. If you think, or were told, that the MBTI is a scientifically based and proven personality inventory then you are misinformed. Industrial Organizational Psychologists who, among other things, work on developing and applying measures and systems for employee section, employee development, and person-organization fit will tell you (in great detail) how the MBTI lack reliability and validity and as such, regardless of its broad use and its broad claims of usefulness is, in fact, not at all scientifically grounded. A measure is reliable if it produces stable, consistent results. This usually assessed by having the same people complete a measure twice in a short period of time so that they have not likely changed much between assessments. To be reliable the measures time 1 scores must correlate with the time scores at about the .9 level of above (1.0 means essentially means the scores are exactly the same). Think about it, if the things being measured should be the same at both assessment times then a much less than perfect correlation likely means that the measure itself is unstable, much like a rubber ruler would be as a length measurement tool. Validity refers to how well the measure predicts what it is supposed to predict (according the relevant theories). Basically, if a measure is not reliable then its validity cannot be assessed. So why use the MBTI? Well listen to the podcast linked below to hear a bit about when, why, and how the MBTI was developed and that may address the question of use (maybe).

The Podcast is here: https://podcast-a.akamaihd.net/mp3/podcasts/current-pjKADs79-20180926.mp3

There are several important points made about the MBTI in the podcast beyond the issues of its lack of reliability and validity. The first is that the dimensions of the MBTI were originally drawn from the work of Jung and tie into his creative thinking about personality and archetypes. Through that work and his related work on things like a collective unconscious, Jung thought deeply and read broadly about the nature and variability of human nature. What Jung did and what the MBTI can do is to get us thinking about who we are and what our basic or preferred social tendencies and needs are as we move about in the world. The results can be broad, dynamic and flexible if not reliable or valid for HR purposes. The historical context of the development of the MBTI is also important. I/O psychology got a huge boost though its contribution to the massive task of assessing and appropriately training and deploying millions of people during the second world war. Just as the massive manufacturing infrastructure built to provision the armed forces in WW2 was repurposed to provision the households and life styles of the retuning veterans and their families so was the I/O Psychological assessment enterprise repurposed to support effective hiring, training, placement and retention practices in organizations. Whether or not this led to an effort, using the MBTI, to convince employees that being personally fulfilled by or at work to the benefit of employers and organizations is debatable. Job and cross-career mobility and contract work have increased massively since the start of the post-war period and a focus of personal well-being and developing a more personal sense of purpose in life, including one’s work-life, is a natural extension of that as well. The bottom line is that if your MBTI results gets you thinking and reflecting then that is likely a good thing but it is also important to note that there are a great many better tools out there not just is the toolboxes of I/O Psychologists and organizations but also available to individuals, like you, who want to take on some of your own talent development initiatives. Go for it!

Questions for Discussion:

  1. What is the MBTI based upon?
  2. Why is the MBTI’s lack of reliability an issue?
  3. What are some of the advantages and disadvantages for employees and potential hires of the broad use of I/O Psychology developed measures in the processes of selecting, hiring, training, developing and retaining employees by organizations?

Description: Do you know what the Marshmallow Test is? (No, it does not involve a campfire and smores).  The test was set up by Walter Mischel who recently passed away at the age of 88. As described in the video embedded in the article linked below, the marshmallow test, I its simplest form, provides young children with a simple challenge. They are seated at a table and a marshmallow is placed on a dish before them. They are told they can have the marshmallow whenever they want BUT, if they wait and delay enjoying the treat until the adult returns to the room (time varies) then they will receive a second marshmallow for a total of two. How do you think young children do I this task? What do you think it would predict if they were able to wait for 10 minutes without waiting the first marshmallow in order to get the second marshmallow? What sorts of things do you think should be included in this sort of test (Mischel added a few things beyond just presenting a marshmallow challenge)? Think about this and them read the article linked below and watch the video it contains to hear what Mischel himself said about the test.

Walter Mischel produced a LOT of research over the course of his thoughtful and prolific career.  The great empirical debate he was involved in was concerned with whether or not people’s personalities are fixed or whether they are open to change or to personal manipulation or improvement. The often stated (erroneously) finding from the Marshmallow test was that children who were able to delay gratification long enough to get a second marshmallow, went on to ore productive/successful lives than children who could not wait. In fact, Mischel was NOT a theoretic supporter of a “carved in stone” approach to personality. In his original research with the Marshmallow test what he showed was that if he taught children strategies for putting off eating the first marshmallow AND if they deployed those strategies effectively, THEN they were more successful in life. Walter Mischel believed and demonstrated empirically, that personality change and change for the better are possible. Thank you Walter.

Questions for Discussion:

  1. What is the Marshmallow Test?
  2. What does the Marshmallow Test show us?
  3. How did Walter Mischel think and talk about the idea of personality mailability and what did his views suggest?
