Cognitive Load Theory: the most important psych theory for teachers ever in the history of everything?

A while ago, Dylan Wiliam (one of my favorite educational researchers) posted this dramatic tweet:

When Dylan Wiliam says something like that, I pay attention! But I didn't find the linked paper easy to digest/apply, and I struggled a bit to see what the BIG DEAL was.

BUT this blog post from Dan Williams helped me quite a bit.


The post walks through the theory with an emphasis on how teachers might USE cognitive load research to help students learn. I get to teach a graduate class in the "Psychology of Teaching" and this might turn out to be a "centerpiece" of the class...

NPR moments, revisited - How Psychology Solved A WWII Shipwreck Mystery


Following up on Chuck's NPR Moments post - A friend at work excitedly told me about a great memory/psychology/mystery story on NPR this morning. He said it was great, details, and that I would love it - he was right!

How Psychology Solved A WWII Shipwreck Mystery

Briefly: Memory researchers used what they learned about how our memories change over time in predictable ways to examine the stories of captured German WWII soldiers and figured out where a ship likely went down. GREAT example of application of research, and the methodology they used in the original "how memories of stories change over time" could be easily replicated by students, I think.

A Picking Cotton update, and more on eyewitness memory

Ronald Thompson and Jennifer Thompson-Cannino, now friends (photo from the N&O)
Every teacher has examples that they must use, and I must use the case of Ronald Cotton when teaching about the problems with eyewitness testimony. In 2009 I posted a link to the "60 Minutes" episode featuring the case of Cotton and his accuser Jennifer Thompson-Cannino, and I recently posted on the AP Psychology e-mail list about how I use the case in class. (I'll re-post an edited version of that e-mail in the bottom of this note.)

Today the Raleigh News & Observer had two disturbing articles linked to eyewitness testimony. The first was a story about Ronald Cotton and other North Carolina men who were unjustly convicted of crimes based on faulty eyewitness testimony. I was very sad to see that despite the terrific book that Cotton and Thompson-Cannino co-wrote last year, things have taken a turn for the worse for Cotton. He suffered a stroke in July which resulted in the loss of the full use of his right arm and leg, and he has experienced significant financial setbacks as well. It's so sad to see this turn of events given that things had been so positive for him since he has been released. The other men included in the article who had been also imprisoned for years before being declared innocent have likewise suffered in their reentry to society.

The second article is the first of a series suggesting serious misconduct on the part of the district attorney in Durham, where I live. The focus is on a man who was arrested and convicted of multiple counts including robbery and attempted sexual assault during a home invasion. At one point, the police detain a suspect, bring the victims to the location where the suspect is held, and ask them together if they can identify him as they sit 20 feet away. The victims confirm that he is the perpetrator, despite the fact that he was shorter than their original description, is not carrying the money he allegedly stole, and he is not wearing the hat or bandanna that the person who broke in had been wearing. An appeals court threw out the conviction, in part based on what they refer to as the police's "use of a highly suggestive show-up procedure to identify defendant as the perpetrator of this crime." DNA evidence later cleared the man of the crime.

North Carolina made significant changes to the way that police do lineups in 2007 based in part on the Ronald Cotton case and the infamous Duke lacrosse case, but this "show up" procedure is still allowed. In a 2010 paper to the Journal of Criminal Law and Criminology (PDF), Michael D. Cicchini and Joseph G. Easton say that this show up procedure "makes already bad evidence even worse, and is even more likely to result in false identifications and wrongful convictions."

As promised, here is how I use the Cotton case in class:

The two videos (13 minutes each) from "60 Minutes" can be found here:

http://www.youtube.com/watch?v=u-SBTRLoPuo (Part 1)
http://www.youtube.com/watch?v=I4V6aoYuDcg (Part 2)

BEFORE you show this, though, I would recommend showing two clips (which also are included in the videos above, in Part 2 I think)  from psychologist Gary Wells at Iowa State. Clip one is a shaky video of someone on the roof of a building, and clip two asks you to select from a lineup the person you saw on the roof in the first clip. This person is suspected of planting a bomb. As you might guess, the person on the roof is not in the actual lineup, but that won’t stop nearly 100% of your students from choosing a person in the lineup. Powerful stuff!

Psychology and September 11



Tonight National Geographic Channel presents George W. Bush: The 9/11 Interview, "a world premiere documentary that reveals exclusive, first-person insight into the former president's experience following the terrorist attacks of Sept. 11, 2001." I will TiVo this program because I'm not only interested in the political aspects of what the president recalls, but also in the nature of that kind of memory known as flashbulb memory. When we experience an event that causes us strong emotion, such as the 9/11 attacks or the death of a famous person, we frequently feel that we know exactly where we were, what we were doing, who was with us, and so forth, because the memory seems "burned in" by a flashbulb, or seemingly captured in a video in our brains.

Most people know where President Bush was when he learned the planes hit the towers in New York City -- he was in a Florida classroom reading The Pet Goat with elementary students. (Did you think it was My Pet Goat? It's not!) But did you know that the president later gave several different versions in the next four months of who told him about the attacks and what he saw of the attacks on TV? In 2004 psychologist Daniel Greenberg of Duke University did, writing a paper in Applied Cognitive Psychology (PDF here) about these inconsistencies.  In one version, for example, Bush recalled that adviser Karl Rove had told him of the attacks, whereas the video footage clearly indicates it was Andy Card. In another version, he states that he saw on TV the first plane flying into the Twin Towers, yet at that time there was no footage on any channel of that event. I will be very interested to compare Greenberg's paper with Bush's events in the NGC special.


Misremembering 9/11 is not unique to President Bush, of course. Psychology teacher Eric Castro recently tweeted about a Scientific American guest blog by Eric Boustead who was in Manhattan and who gives a very detailed description of some of his experiences of that day - what he watched on TV, neighbors coming together, even enjoying a corn muffin baked by his downstairs neighbor Serena. Later he contacts his former roommate to hear his remembrances, only to learn that their TV was only hooked up for games (thus no TV news), Serena didn't move in until a year later, and the roommate had no memory of the food - as the roommate put it, "I mean why would we be eating muffins during all of that anyway?"




One of the most brilliant insights immediately following 9/11 also came from Duke University, this time from Jennifer Talarico and David Rubin, who brought small groups of undergraduates in on September 12 and asked them to record what their memories were of 9/11. The brilliant part was that they also asked them to record what they remembered of some personal everyday memory that had happened in the preceding couple of days, such as a party, a study session or a sporting event. When they brought the students back one year later, Talrico and Rubin found unsurprisingly that the memories of both flashbulb and everyday memories had similar errors in consistency, but the students rated their confidence in the 9/11 memories much higher. In other words, their memories of both events were equally flawed, but the flashbulb nature of the 9/11 made them believe much more strongly in those memories. (The video above (also linked here) is of cognitive neuroscientist Elizabeth Phelps describing this study and 9/11 memories in general at the World Science Festival.)

One other quick pointer: the September 2011 issue of American Psychologist is devoted to the events of 9/11 and its effects in many areas, including post-traumatic stress, memory, social consequences, group dynamics and more. The introduction to "9/11: Ten Years Later" can be found here (PDF).


The 10th anniversary of 9/11 will be an interesting challenge for us as psychology teachers. If you are teaching primarily high school juniors and seniors, for example, those students were probably between 6 and 8 years old at the time. Not only will their memories of the event be as fuzzy as everyone else's, but they will have had less of an opportunity to even be exposed to the coverage that day and in the days that followed, as their parents may have shielded them from the news. Nonetheless, they have grown up in the shadow of 9/11 and their lives have definitely been affected by those events. There was a great article in the Washington Post in 2009 about the challenges of teaching students too young to have experienced this firsthand, though some of the frustrations I perceived in that story seem more pointed toward work in general and maybe very little to do with 9/11.

So - how will YOU teach about 9/11? Please add a comment below or e-mail me directly (ashejones@gmail.com) and I'll post your reply anonymously.

Smithsonian Magazine-Memory and More

I've been reading from Smithsonian magazine for a number of years, but had never thought to visit their website due to the relatively few directly psych-related articles in the paper-version.  In their most recent issue (May 2010) there is an excellent article on memory and how memory works.

 As I perused the online version of the article, I noticed that they had several other sections with articles of note.


Articles on the Brain
Articles on Psychological Issues/Topics
Thought Innovation & Behavior--which could have some articles of interest


Overall, if you like to read quality writing on any topic, I recommend the magazine/website.  Great stuff there.

Schemas--a great demo

I posted this recently on the AP Psych Listserv:

Schemas are a core concept that I have in all my psych classes--they are the key idea around which I create everything else (except biology).  I use the Drew Appleby Demo on Déjà vu, not for that concept, but for the creation of a false memory based upon our schemas.  The PPT I use is here:
https://sbhs-sbhsd-ca.schoolloop.com/blogdocs

Description of the activity I give I created for a textbook video lessons project and can be found on YouTube here: http://www.youtube.com/watch?v=rVEu3OVh3Uw&feature=related

The debriefing is here:
http://www.youtube.com/watch?v=m2nEM-oT0Kw

The demo has worked perfectly for the past 15+ years.  Feel free to use and adapt.

For an assimilation example, I use "Monster's Inc." and the little girl "Boo" who calls Sully a "kitty."  He's obviously a monster to us, but she does not yet have that in her schema, so she uses what she has available already--furry, with ears, four legs and a tail means "kitty."  So far as I could tell, she never accommodated the idea of monster with Sully--she only had that with Randall.  She distinguished the two.

Memory Studies on APA's OPL

Back on April 24th of this year (2009), we posted a blog entry with information on the APA's highly interactive Online Psychology Laboratory (OPL) (http://teachinghighschoolpsychology.blogspot.com/2009/03/opl.html). The laboratory has a number of memory activities for students to partake in. In fact, the memory unit is second only to sensation and perception for the amount of studies.

Below you will find a listing of the seven studies currently on the OPL. Simply click on the item below to go to the study. Please be aware, the site requires teachers register and obtain a class ID.

To register your classes go to the homepage for the OPL at http://opl.apa.org/Main.aspx

Short Term Memory Demonstration

Gary Fisk from Georgia Southwestern State University, has developed a animated short-term memory demonstration. Students are asked to remember a sequence of numbers which grows from four to eleven digits. While rather simple, the animation gets the point across.

The memory animation can be found at Dr. Fisk's personal website at http://garyfisk.com/anim/lecture_stm.swf. Dr. Fisk has created a number of other animations teachers may find useful. Go to http://garyfisk.com/anim/index.html for more information.

Online Simon Game

Wikipedia describes Simon as "an electronic game of rhythm and memory skill" (http://en.wikipedia.org/wiki/Simon_%28game%29). The game was a pop culture phenomena of the 1980's with Milton Bradley selling millions. While not as sophisticated as the video/computer games of today, Simon can still be fun to play.

For an online version of the game go to http://www.freegames.ws/games/kidsgames/simon/mysimon.htm

Creating False Memories

This is an excellent article written by Elizabeth Lofus, one of the top experts on eye witness testimony, for the September 1997 issue of the Scientific American. The article, "Creating False Memories", provides not only information on false memories, but includes research on the planting of a false memory.

The article can be found at either of the following two websites, https://webfiles.uci.edu/eloftus/Loftus_ScientificAmerican_Good97.pdf?uniq=-jd60qg or http://faculty.washington.edu/eloftus/Articles/sciam.htm

Teens and Memory Cartoon


I saw this today and immediately thought of psychology. Of course, I look at nearly everything and ask myself if it will fit into class. With this cartoon, I thought of memory, rehearsal, encoding, and, of course, interference--specifically retroactive interference, the kind where new information impedes the ability for old information to be there. While it may not fit exactly, it is a fun connection.

Miller's Seven Plus or Minus Two Experiment

The Classics in the History of Psychology include a copy of George A. Miller's invited address to the Eastern Psychological Association detailing his studies on the limits of memory. The talk entitled "The Magical Number Seven, Plur or Minus Two: Some Limits on our Capacity for Processing Information" was later published in the Psychological Review.

The article might provide an ideal opportunity to not only discuss Miller's findings, but also the various ways scientists present their research findings.

Miller's article can be found at http://psychclassics.yorku.ca/Miller/ For additional information on Miller's research on memory go to http://www.intropsych.com/ch06_memory/magical_number_seven.html

Face Memory Test

The Science and Nature: Human Body and Mind portion of the BBC's website, includes a short demonstration on remembering human faces. While the primary intent behind the activity involves how the lack of sleep influences memory, the Face Memory Test would probably fit better in a Memory Unit rather than the States of Consciousness section of the class.

There are three parts to the activity each separated by a five minute break where students are shown a variety of faces and then later tested on which they can recognize. It should take between 15 to 18 minutes to complete the full activity.

The BBC website is located at http://www.bbc.co.uk/science/humanbody/sleep/tmt/

"Executive Function", self-control and kiddos


This recent article in the NYT about "Executive Function" helped me make some connections between topics in intro. psych. The article discusses efforts in classrooms to help students with self-control and links this ability with the development of "executive function" (cognitive psych concept that I'm not sure is in most intro. textbooks yet?)

One of my favorite activities demonstrates executive function very dramatically - "Baddeley's Three Systems of Working Memory" . Next time I do this demo, I'll be able to talk about the connection between executive function and self-control.

A good topic for students might be connecting all this with the famous "Marshmallow Test" about deferred gratification, or even Skinner's proposal to hang lollipop's around children's necks and reward them for NOT eating the candy.

Using Columbine in your class

I recently finished Dave Cullen's Columbine and highly recommend it. I was teaching psychology ten years ago when the events at Columbine unfolded and I was certainly tuned in as to why it happened then, but honestly haven't followed any news about it since just a few months after the shootings.

That being said, I was stunned at the amount of misinformation that I had internalized and believed to be true about the killings: the killers weren't part of the Trench Coat Mafia, there was no plan to take out jocks because the shooters were being bullied, this wasn't a spontaneous act of anger and what did happen was only a small part of the plan, most of which failed miserably. A number of the myths are described here in more detail.

As usual in chaotic scenes like this one, the study of memory and eyewitness testimony leaps to the forefront. Cullen was on the scene the day of the shootings and saw a marked difference in the interviews of students that day as opposed to what the students were saying later in the week. When students went home that night and watched the news about the shooting they picked up bits of pieces of information and through confabulation created entirely new memories of what the killers were like and what transpired that day. Even the beloved Columbine principal discovered years later that his memory of being initially told about the kilings was completely wrong; Cullen notes that "Mr. D." understands from two witnesses what he is supposed to have done, but holds on to the wrong memory as well because he can see that one in his mind.

Another major contribution to psychology from the book is the analysis of the shooters. Again, from a distance, I didn't pay attention to any differences, but Cullen does a nice job as an armchair psychologist of diagnosing the boys based on numerous journals, writing assignments and video diaries left behind. Dylan comes off as a depressed loner who was bright but suicidal, and just followed the plan laid out for him. Eric, though, is the prototype of antisocial personality disorder: the manipulation, the ease of lying, the lack of conscience, empathy, remorse, etc.

How about you -- did you mention the shootings at Columbine in your classes last week? Were you a teacher or student in '99 and remember experiencing this? Are you surprised at how the myths have been perpetuated? Should Oprah have canceled her program on Columbine last week -- do we indeed give the killers too much attention by focusing on them at all? Have you read Columbine and have your own opinion? Weigh in below in the comments and share your thoughts.

Psych in the news

Seriously? There is so much news flying by I'll never catch up. Today's installment is in fast forward with a minimum amount of words, no credits and crammed in every which way.

Calculating very rare events * Do psychologists still use Rorschach tests? * The mental heath of Iraqis after years of war * How ads enhance TV watching * The flexibility of dream interpretation * Does stress cause gray hair? * Older dads linked to lower IQ kids * Single sex classes in public schools * Placebos in teen depression studies * Brain differences between the religious and non-religious (and hear the NPR report) * Psychology and neuroscience on Twitter *

Two longer ones to end on: shark attacks are dropping and the economy's to blame! (Does anyone else use the correlation does not equal causation example of shark attacks and ice cream sales? So now shark attacks and the economy are correlated?)


Finally, a WARNING: this article in the Washington Post magazine on children dying in cars accidentally because they were forgotten by their parents is difficult to read (or at least it was for me -- there are parts I just had to skim through). I add it only because of the questions it raises about memory, inattention, distraction and people being off of their routines which leads to forgetting. There's also a sidebar on ways to prevent these tragedies -- sure, there's some technology, but there are also the simple things like putting something that you need for work (ID badge, briefcase, keys, etc.) in the back with the child. Kids and Cars also has other devices.
