Description: Quick! Who is happier, or who is more often happier, introverts of extroverts? Well, consistently research seems to show that extroverts are happier than introverts more of the time. Why do you think that might be? If it is the case that being extroverted or perhaps acting in an extroverted manner makes you happier what do you think would happen if we counselled, encouraged, or simply asked people to act in more extroverted ways. If they are introverts and role-play being extroverted what do you think will happen to their level of happiness? Also, what think about how the study should be designed to properly address this hypothesis? Once you have thought it through give the article linked below a read and see how the researchers who conducted the studies is discusses handled the design question and what they found.

So, the past finding that “acting like” an extrovert makes everyone including introverts happier is not as solid a finding as was once thought. This is interesting given the large number of “fake it until you make it” strategy suggestions there are out there. There DO seem to be short term mood bumps, but maybe longer terms outcomes are not as resoundingly positive as was once thought. What does that suggest about claims like — acting extroverted buys you extrovert benefits? Well, of course, as the article author suggests it indicates that more research is needed but what should we look at to try and sort this out? What do you think? Maybe impacts on our personality are the rolling sum of our actions in many social situations and, if so, a positive mood bump from a single social situation will get averaged out pretty quickly. Interesting and, indeed, more research is needed!

Questions for Discussion:

  1. How does acting in extroverted ways impact our mood states?
  2. Why might extroverted behaviour lead to a short term mood bump?
  3. What do the results of the study discussed in the article linked above suggest for the “fake it ‘till you make it” personal improvement or advancement strategy?

Description: These days, and with increasing frequency as the November 6, 2018 American midterm elections approach, when people I meet find out I am a psychologist I am often asked some version of a “… so what is with Trump” question or in other words questions about how for “out there”  is Trump or is, or what kind of disordered is he? In responding to such questions I usually start by saying a couple of things: First that as a developmental psychologist I am not formally qualified to provide individual diagnoses of psychological disorder and second that, in line with the ‘Goldwater rule’ and with general ethical principles laid out by the Canadian and American Psychological Associations even if I were diagnostically qualified I have not met or psychologically assessed Donald Trump and am therefore unable to offer a diagnostic opinion. Boring huh? What I usually go on to say though, is that being a psychology teacher (33 years) I love to talk to people about Psychology and Psychological disorders and then I ask them what parts of Psychology and Psychological disorders they think might apply to Mr. Trump. We can then talk about Psychological theories, concepts, disorders and diagnostic criteria in general without my having to offer and opinion of the state of Mr. Trumps mind (though, privately, I have a few of those). So, from a psychological perspective, what do you think of Donald Trump? Once you have your thoughts in order read the article linked below for a discussion of possibilities and limits (and there are a couple of related articles in te Reference list down below that you might find intersting too).

So how did that “conversation” go for you? Do you understand the difference between personality disorders and psychiatric disorders such a depression and schizophrenia? The nature and status of personality disorders are much debated especially by those charged with potentially revising that section of the Diagnostic and Statistical Manual. It is perhaps best to think of personality disorders as extreme personalities that are reflective of enduring ways of being in the world, rather than disorders that have specific point of onset and realistic probability of recovery (which is a standard introduction to abnormal psychology slide and lecture point). This means that personality disorders reflect behavioural tendencies or traits that many people use once in a while but that some people come to have define them and their actions in the world on an ongoing basis. I suppose one of the most depressing or alarming realities about personality disorders (in light of the number of ways narcissism comes up in discussions about recent American presidents) is that it is hard to treat, largely because those who meets its diagnostic criteria do not believe that they have a problem or that they need treatment. It reminds me of a scene from the old television show Frasier in which Frasier’s brother Niles (also a psychiatrist like his brother) says, as he is leaving to run his regular group therapy session for personality disordered lawyers, “I love working with lawyers,… they have lots of money and they never get better.”

Questions for Discussion:

  1. How are the features of personality disorders different from the features of plain old, ordinary personalities?
  2. Why should psychologists refrain from “diagnosing” public (political) figures?
  3. What sorts of things might be said or hypothesized about in relation to hypothetical questions like – If Donald Trump does, in fact, meet the diagnostic criteria for narcissistic personality disorder what might psychology have to say about why so many American voters were and seem to be attracted to him (see the article link related to this in the References section below)?

Description: You have undoubtably seem or heard the increasing buzz about driverless vehicles and you might think that the one thing you do NOT need if your vehicle has no driver is Psychology. But, think about this – driverless vehicles work the way they do because of how they were designed and a crucial part of their design has to do with how they are going to “make decisions” out there on the road in the world where there are going to be real people. So, think of this – moving through the world and interacting with people requires that we make ethical and moral decisions regarding the potential impact of our actions (or our lack of action) on other around us. So here is a BIG question – what sort of moral decision-making rules, strategies or decision-making algorithms should we program into driverless vehicles before we allow them our to share the roads and the world with us? Didn’t see that one coming, did you? So, try and get your head around that question and then read the article linked below for a multinational perspective on it.

So, what do you think? Does it make sense to work at having the driving morality of autonomous vehicles reflect local beliefs and moral demands? What are your core driving decision-making peices? Numbr of potential acasualities? Age of Casualties? At a minimum the research as the researchers suggest, could provide a framework for both local discussions about what we want of autonomous vehicles and about what might distinguish local from general guidelines for such important programming.

Questions for Discussion:

  1. Does it make sense or is it important to talk about the morality of driverless vehicles?
  2. What sorts of driving dilemmas or questions should the programmers for autonomous vehicles be working on?
  3. What might be some of the wider implications and applications of this line of research and refection (like who is liable if something goes wrong)?

Description: Did you every keep a diary? How about now? Do you write regularly in a diary or, perhaps so as not to suggest a dramatic teenager, do you journal regularly? Just think for a minute, not about the stereotypes associated with keeping a diary but, from a psychological (adjustment, reflection, self-care, and/or a developmental) perspective, what advantages might arise from reflectively putting pen to paper or cursor to word processing program on a regular (daily!) basis. If you were going to research the impacts and benefits of journaling what might you look at and how might you measure it and who would you recruit to participate in the research? Once you have a few hypotheses and research approaches in mind (and dismissing this as stooooped and childish IS channeling a dramatic teenager — so get over that) have a read through the article linked below and see what sorts of angles people and researchers have taken in understanding the value and impacts of journaling.

So? I bet you did NOT predict that journaling would reduce the time it takes for physical (not just psychological) wounds to heal! When I am lecturing about identity development and life planning I find myself coming over and over again to one or another version of telling students they should find some ways to regularly reflect upon what they are thinking about, worrying about, trying to figure out, and where they are going with all that. A HUGE part of what it means to positively enter into adulthood (whatever that means) these days requires the application of reflective powers and perspectives that only become available to us in the stage of emerging adulthood (18 to 25 to 29 year of age). Journaling really does facilitate that sort of self-design developmental work. Likewise, mindfulness (you cannot have missed the recent huge spike in postings on this topic) involves both working at being more “in the moment” and being more reflective and personally philosophical (all aided by journaling). So, I don’t not think we necessarily need to leap into seeing journaling as a means of spiritual self-illumination, rather, I see it as a way to take more conscious control of the natural developmental emergence of an ability to reflect upon our place and purpose and navigational direction in the world (and in a world that IS more complex and diverse than it was for previous generations). So take up a pen, a keyboard or your agile thumbs and get going on a regular journaling habit, wo knows where it will take you!

Questions for Discussion:

  1. What is journaling and how does it differ from writing in a diary (if it does)?
  2. How does journaling relate to mindfulness?
  3. Describe 3 to 5 areas of research into things like self-awareness, career planning, and life adaptation and satisfaction that journaling could play a vital role in?

Description: This is the last of three posts relating to anxiety and research into its prevalence and management. For students in high school and especially in college or university, anxiety can be a regular occurrence. Particularly as one moves beyond high school and out into post-secondary life there are many things that can give rise to thoughts of and physiological reaction to stress and stressful situations and to feelings of anxiety, both short and longer term. While emerging adulthood – starting aroudn18 years of age – can be approached as the starting point of a life-long personally managed journey it can (and actually should) also come with challenges like uncertainty and, yes, anxiety. The other posts this week dealt with things you can do to manage or to reframe anxiety either as manageable or a guide to challenge and excitement. There is a LOT of Psychological research on the prevalence and management of anxiety disorders among emerging adults (college and university students) but most of that research, perhaps understandably, focusses on anxiety and related disorder categories within the Diagnostic and Statistical Manual and not on the subjective experiences emerging adults may have with anxiety or on the ways in which those subjective experience of anxiety might increase, decrease or otherwise morph and change as you move into emerging adulthood. Before you have a look at the articles linked below think a bit about your experiences with anxiety in your recent life. Have things changed in this area since you left high school? For the better or for worse? How do you think about, approach and, hopefully, manage the situations that make you feel anxious and/or your feelings of anxiety when they bubble up? The first linked article is very general and talks about recent research looking at the prevalence of mental health issues among first year college or university student world-wide. The second article, hopefully, will relieve any, or at least some of the, anxiety potentially generated by the first article by talking about the difference between “simple” feelings of anxiety and anxiety disorders. Between the two articles lies one of the tasks of emerging adulthood – figuring out when you need help and how to get that help with anxiety as a symptom and when some of your new inner experiences of anxiety are reflective of or arise from things that YOU need to understand and figure out how to deal with for yourself (though there can be help for that too!).

I suppose one take-away from a read through these two articles is that being a first-year student is hazardous to one’s mental health and that even when that is avoided there is still plain old anxiety to struggle with. More constructively, however, another interpretive option is to view much of your recent or current life anxieties as transitory or, perhaps better, as developmental. If you can reframe your current life experiences and the feelings and stresses related to them as identity relevant sources of data that you can build upon or with as you start to chart out and then embark upon your personal/adult life journey I suspect you will find that your anxieties will diminish as you take them on and move past them. For some tips on how to go about doing that enter the search term “life design” into the site’s search bar up at the top of this screen and see what you find. Good luck!

Questions for Discussion:

  1. What is the difference between feelings of anxiety that are part of life in emerging adulthood and an anxiety disorder?
  2. In what ways have your experiences with anxiety changed since you left high school?
  3. What are some of the ways in which feelings of anxiety might lead to positive life experiences (experiences of personal growth)?

Description: What do you, or how do you, think about anxiety? When you feel anxiety rising is that a sign you should stop what you are doing, or do less of it? Anxiety is typically seen as a sign that something potentially threatening or dangerous is starting or is about to happen and we can easily see anxiety as a sign to withdraw from the field, as it were. But what if we were to think about the signaling system that is made up of our physical and associated psychological experiences with anxiety as a sort of wild horse that, if tamed, might be bent to our advantage? Think about the similarities between the feelings associated with anxiety and those associated with (anticipatory) excitement. Ignoring the future event involved can you describe, in detail, the differences between the two? If not, what might that suggest to you as a way different way of thinking about or a different mindset related to anxiety? Think about that and ant other mindset shifts that may come to mind and then read the article linked below, written by a psychologist who has thought a LOT about these questions.

Alicia Clark, in the article linked above and in her book on the same topic suggests we work on thinking differently about anxiety. What is anxiety? A signal that something bad is possible going to happen? Or perhaps it is just a signal that we need to pay attention to an impending challenge/opportunity. Anxiety is anticipatory, but what if we view it as an indication that we need to gear up our problem-solving resources? Reframing your thoughts about anxiety not as a portent of doom but as a sign of potentially positive change can be helpful. Stepping into rather than away from our feeling of anxiety can make a big difference in your outcomes. Sound too simple, or too good to be true, well have a look at some of research linked in the article and in the residence list below because you should never just take my or anyone’s word for this sort of thing. Look at the data!

Questions for Discussion:

  1. How do you respond when you start to feel anxious?
  2. What does the author of the article linked above suggest you do when you start to feel anxious that is different than how you responded to the first question above?
  3. Did the research articles below and linked in the main article discussed above provide you with support to make changes in how you think about anxiety? If not, what additional research would you like to see done?

Description: There are indications that the number of young adults dealing with high levels of anxiety or worrying about their current levels of stress and anxiety have jumped up quite a bit in recent years (see Reference Section below). In this and a related post to follow shortly I am going to look at a couple of research questions regarding anxiety and coping with anxiety I particular. I will likely return to this area again soon as it is an important one in relation to the life experiences, satisfaction and adjustment of emerging adults (18 to 25 or 29 years old’s). This post looks at an article discussing a study into social anxiety, or at the anxiety that many people feel as they approach a social event, situation, or performance that they are anxious about. The question that drove the study may seem like a simple one – Why do some people’s anxiety levels seem to ramp up dramatically as the event approaches? And more importantly, what sorts of things might they be doing, or not doing that either contribute to this ramping up of social anxiety or that, at least, do not seem to be helpful in reducing it? Think about a social event that you were or are anxious about and think about the sorts of things you do as it approaches. What do you think about? What do you think about your feelings of anxiety and what sorts of things (if any) do you do to try and manage your feeling of (blossoming) anxiety? Once you have your thoughts in order read through the article linked below and see what the researchers looked at and what they found (and how they designed their study).

So, did you see the finding about negative rumination coming? As the author of the article linked above points out, research has shown that cognitive behavior therapy can be quite helpful in dealing with social anxiety issues, but it has not been clear what aspects of CBT actually provides the beneficial effects. Relatedly, it is interesting that going over and over what might go wrong at the social event is actually NOT a good strategy for ensuring bad things do not happen but is, rather, negative rumination that tends to escalate rather than reduce social anxiety. What the research suggests is that trying and practicing detached mindfulness – noticing yourself starting to ruminate about an upcoming event and telling yourself to stop or to now think about it seems to be quite helpful. It is important also to think a bit about the design of the study — using undergraduate students who did not actually have anxiety disorder issues – and think about ways in which we should be cautious about how widely we apply the results and about what research we still need to do in this area. The research is, most certainly, a promising start not only in helping those with social anxiety issues but also clarifying our understanding of how social anxieties emerge and propagate in peoples’ lives.

Questions for Discussion:

  1. What is social anxiety and in what sorts of situations does it arise?
  2. What sorts of things do people with social anxiety issues do in the time leading up to a social event (the anticipation of which) that is causing then anxiety to amplify or reduce their feeling of anxiety?
  3. What is detached mindfulness and what specifically would you do to use a version of it if you had a social event coming up that was starting to make you feel quite anxious?

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?
