Why We Spend When We Shouldn't

A front page article in today's Globe and Mail by Tavia Grant on why retail sales seem to be strong this year despite wage stagnation and vacillating consumer confidence included some "sage" words from yours truly! :)

The questions Tavia asked are really good ones and are at the crux of much of what I research. Part of the explanation could be attributed to the pent-up demand effect, where even if consumers are financially limited and they try their best to resist the urge to spend and be frugal, when there are cues from the environment, like ubiquitous reminders of the rapidly approaching holiday season, or when there are stressors or pressures, due to worry about one's job or the economy for example, theory from psychology and consumer behaviour posits that people may be even more susceptible to the temptation to spend even when there is uncertainty that the cash is available to pay for these purchases. So while we might expect that a dip in consumer confidence might dampen spending because people should be preparing for what they expect might be harder times, in fact it can be difficult and stressful for people to cope over an extended period of time with that fear and trepidation. In addition, because we have certain cultural expectations of what an ideal holiday is and often it is important to at least provide a happy experience for loved ones it makes sense that people would muster up any surplus, whether from a savings account or a credit card, in order to make the best of hard times. This can result in surges in spending even during declines in consumer sentiment. In a nutshell it is still difficult for us to predict how consumer confidence impacts consumer spending given the idiosyncrasies of how we psychologically consumer when under stress. There are many other factors that can modulate that impact. I think that some of us react to the uncertainty in the environment by looking for ways to feel confident, in control and successful and interestingly the process of shopping to procure consumption items especially for our households and families is very satisfying, very rewarding.

Brining A Whole New (Other) Meaning to "Businesswomen" Around The World

The Economist's Schumpeter column, which I often vehemently disagree with for its extreme opinions, hit a home run last week with The Daughter Also Rises: Women Are Storming Emerging-World Boardrooms. It chronicles the sagas of numerous female "businesswomen" (which in Russia has a less than flattering double meaning...who knew? See the article!) in emerging markets around the world and the painful but steady shifts that working, educated even millionaire and billionaire women are making in places where culture has stood firmly to dangerous and lethal beliefs about what half the population can and can't do!

What are video games good for? Maybe quite a bit! A reluctant mom considers the benefits.

My son has been trying to convince me for years that video games and computers, which he has an innate love of since the age of 1 1/2 (yes, I let my toddler play on computers...naughty mom!!). He recently wrote an articulate and thoughtful essay for his 7th grade language arts class on how video games can change the world. It included his belief that playing games online or on consoles helps him to meet kids all around the world, learn new languages like Chinese and Japanese, read faster, think better, learn how to solve puzzles, plan and strategize, and the list went on and on...I have spent years yelling at him to turn off the computer, obsessing about how much I suck as a mom because my kid sits sometimes for hours staring at a screen and worried about what he will do as an adult if all he can do is click the mouse really fast.

But my eyes have been opened since I have started to think about what it really means to reach a level of optimized human performance. My husband, who is a big my husband, who is a big proponent of virtual worlds and MMORPGs (Massively Multiplayer Online Role-Playing Games) including WOW (World of Warcraft for those of you non-gamers out there), told me to check out Jane McGonigal's TED video on how video games can change the world...I was impressed with her narrative (it helps that she talks in PhD-speak which I have learned to love)...and maybe I can be convinced that video games can save the world!

Treating Alzheimer's by stimulating the brain with Transcranial Magnetic Stimulation

Alzheimer's is a tough disease to deal with...how can any of us stand to be without the parts of the brain that make us who we are? My mom is right now dealing with early onset Alzheimer's and since my grandmother and grandfather both died from it, I wonder how long it will be before my absent minded professor habits turn into full blown dementia in my overstressed, sleep-deprived mind...An article in Technology Review from MIT looks at new technologies being developed to help Alzheimer's patients recover cognitive functionality without the use of drugs. One being developed by Neuronix uses transcranial magnetic stimulation (TMS), which researchers I know used in their work, in order to activate or deactivate specific regions of the brain as a way of circumventing neuronal damage. If this can become a way of treating the +5M people who are currently suffering along with all of their caregivers and those who love them, it will be a huge step forward!

Using light to measure brain activity

ScienceDaily  -- Radiologists have developed a new device to understand brain activity. It is a collection of fiber optic cables attached to a flexible cap placed atop the head. The cables send near-infrared light through the skull and into the brain, where it is diffused or scattered before it is collected by receiver cables. The device is able to interpret the light to measure blood circulation and the amount of oxygen in that blood, which helps explain brain activity.

Trend Hunting 2011: All You Need to Know!

One of the most important skills anyone can have is one of forecasting...being able to "predict" the future is massively useful but notoriously difficult as any academic article from the International Journal of Forecasting deftly shows. But I personally love trend tracking! I have been dabbling in it since my early days in the ad business at Young & Rubicam NY and while you don't always get it right, it is cool to see which trends hit and which ones miss. On a recent trip to Toronto, I read a magazine article on the founder of www.trendhunter.com Jeremy Gutsche and I was intrigued. This is all about crowdsourcing global trends! What a great way to track everything happening in food, clubs, fashion, design, business then to ask the mob to flash mob the latest! Here are their prediction for 2011:

Soldiers Brains Vulnerable to Significant Change Under Combat Stress

Soldiers’ brains adapt to perceived threat during mission

ScienceDaily (2011-01-26) -- A study of soldiers who took part in the ISAF mission in Afghanistan between 2008 and 2010 has found that their brains adapt when they are continuously exposed to stress. The perceived threat appears to be the major predictor of brain adaptation, rather than the actual events. In other words, if a roadside bomb goes off right in front of you, the degree to which you perceive this as threatening is what counts. This is what determines how the brain and the stress system adapt. Between 2008 and 2010 the researchers studied a group of 36 soldiers. Before and after taking part in the mission, the soldiers’ brain activity was measured and compared with the brain activity of a control group of equal size who stayed at home. Unique to this study is that it is the first to use a control group. This control group, which stayed behind in the barracks in the Netherlands, had received similar combat training. ... > read full article

Cues That Drive Violent Behaviors


An recent article at CNN.com by Prof. Saul Kassin on the psychological theories that might explain what drove the shooter in Arizona, reveals some interesting findings on what underlies violent behavior.

1) Men who show antisocial behavior as children such as truancy, setting fires, abusing animals, often are diagnosed to have psychopathy. These are the same adults who do not show empathy, aren't able to show real emotions, often are unfeeling in relationships and engage in high risk and even unethical behavior. From my observation many of them end up in business school and eventually in business which makes teaching ethics so hard to do!

2) Men are much more likely to commit violent acts than women and there is some evidence that violence is linked to testosterone levels. Kassin mentions in his article that "roid rage" - the heightened propensity men on steroids often experience - seems to be related to the increased level of testosterone.

3) Even when there are behavioral precursors that might indicate a violent episode for an individual, often an event that triggers frustration increases the likelihood for violence. This frustration can be caused by social or economic failures but interestingly can also be caused by pain, heat, insult, jealousy and rejection. Those are conditions that people who are concerned about an individual can look out for but unfortunately there's no way of shielding a vulnerable individual from these types of events.

4) These violent acts are not spontaneous. They are often well planned out a study by the U.S. Secret Service found when looking at 37 shootings. In many cases the perpetrator discusses their plans with at least one adult and/or classmates. We need a better mechanism for people to report this type of foreknowledge!

4) The most interesting part of Kassin's article was his assertion that studies have shown that just the presence of a weapon (vs. not present) makes people more likely to administer painful electric shocks to strangers. The effect of this cue could potentially be a powerful, subversive one especially when we think of the prevalence of weapons and violence in the media. And this exacerbated by individuals who are exposed to these cues who might be vulnerable in some way!

Many of us know of individuals who could potentially "pull a postal" because of their personality, behaviors, current life state, isolation, and frustration. It is unfortunate that even with this knowledge it is difficult to know how best to deal with this concern.

Beyond that, it is important that more research be done to understand how cues in environment might affect or trigger behaviors that are dangerous...with that knowledge, we might be able to decide how we might choose to articulate commercial products such as games, TV shows, ads, in order to try to foster a more safe and civil society.

If you're lazy, you don't participate in politics

New article in Psychological Science...so amazing even Huffington Post commented on it!

Participating in Politics Resembles Physical Activity: General Action Patterns in International Archives, United States Archives, and Experiments

Kenji Noguchi, Ian M. Handley, and Dolores Albarracín
Political participation may be linked to general action tendencies. Greater action-tendency index (e.g., percentage of people exercising 5 or more days per week) was shown to correlate with greater political participation (e.g., voter turnout) in the 50 states and the District of Columbia for the 2004 U.S. presidential election. In addition, volunteers who were exposed to action words (e.g., go, move) had stronger intentions to vote in an upcoming election and volunteered more time to a calling campaign on behalf of a university policy than volunteers who were exposed to inaction words (e.g., relax, stop). These findings suggest that voting campaigns reminding people to "take action" may be effective in mobilizing citizens to vote and participate in political activities.

New Book: The Dragonfly Effect by Jennifer Aaker and Andy Smith

Next on my reading list is a new book by marketing professor Jennifer Aaker and Andy Smith, The Dragonfly Effect.

This book offers readers how to use social media in order to unleash unprecedented results for the benefit of society! My new year's resolution is to learn how to use blogging and tweeting as a way to practice writing more for enjoyment and self-expression, feeling that I don't feel when in my academic writing. But any form of writing must improve all forms of expression, so my thinking is that in this way social media is helping me to stretch my abilities and talents to a new level.

I'm really looking forward to reading The Dragonfly Effect! It is an important book that could offer some real practical tactics to exploiting this wonderful new medium of social media!

Noise, Distraction Makes You Naughty...You Eat More!

One of my favorite theories to study is cognitive resource depletion, which says that your ability to resist temptations and focus your attention is limited and once you run out you aren't able to stop yourself from doing all sorts of naughty things.


A recent article on NPR reports on a study by Andy Woods at U. of Manchester which found that people who were distracted were less likely to distinguish sweetness and saltiness. Suzanne Higgs at U. of Birmingham found that when people were distracted during lunch they were more likely to eat more cookies later in the afternoon!

So why does distraction during eating make us eat more? It may be that distraction distorts the brain's ability to process perceptions of foods we are eating but that remains to be uncovered by more research. And yes that is indeed on my long to do list!

Warding Off Bad Vibes with Images, Colors: An Experiment for Your Back To Work!


Today I've been contemplating going back to the office on Monday after a nice, productive holiday break. One thing I'm not looking forward to is the inevitable interrupting visit to my office of somebody with some bad news or information that I just don't want to be bothered with! We all suffer from these "Debbie Downers" at the office...they can upset, disturb, distract, and ruin a perfectly good day! But I was thinking back over the last few months since I moved into my new office and noticed that I've had significantly fewer annoying interruptions from bad personalities (the visits from people with great news and wonderful ideas has actually continued uninterrupted!) ever since I did one thing about a month after moving in...

I hung 4 two by three foot color images of flowers I photographed several years ago. They are posted throughout this blogpost!

Before I hung them, almost everyday I had some unusually sour tempered person come into my office and unload...either my research idea wasn't that great, or teaching this year will be impossibly hard, or my approval wasn't going to be granted on something. Oh, it was tough to keep going after getting sideswiped midday like that. But since those 4 images have gone up, all that has stopped...nothing but good news. People even come by just to talk about photography and almost everyone comments on the images when they walk in. Could these images and their hues of yellow, green and blue, prime people to behave differently?

While imagery in advertsing has been looked at quite extensively in the consumer behavior literature, there is a relatively new body of literature that is beginning to look at the effect of color. Mehta and Zhu from U. of British Columbia did a great paper in Science on the effect of red and blue on approach and avoidance behavior. I am collecting data next week that will hopefully build on these results trying to understand the effect of color on risk behavior.

So I have a challenge to you! Try this experiment in your office or home to see if it changes how people act when they come in. Download these images, print them out (in color of course) and place them in prominent view wherever you need a little protection from people with bad vibes. Observe whether there's any change! Let me know if you see a difference or not...I'd love to know whether this is really an effect I'm noticing or just random chance!!
