My Memories of Anders Ericsson

On June 17, Anders Ericsson, a giant in the field of psychology, passed away. Neil Charness, who knew Anders Ericsson much better than I did, has written a heartfelt and beautiful in memoriam. Here, I am merely describing some memories of the 13 years that Anders was my colleague.

At the 1993 Annual Meeting of the Psychonomic Society in Washington DC, I was on my way to a poster session, when I was approached by a bearded and somewhat burly gentleman in a blue blazer. He was extremely polite, introducing himself by making slight bow, which I thought was both quaint and endearing. It was Anders Ericsson. I told him I knew his work on protocol analysis and, in fact, owned his 1984 book with Herbert Simon, which I’d bought as an undergraduate student. He told me there was an assistant professor position in his department and if I considered applying.

Several months later I had accepted the position. And a few months after that my small family and I moved to Tallahassee in June, 1994. Anders had very generously offered to pay for my summer salary out of his endowment, allowing for a very smooth transition, making me feel at home in the department right away. One of my earliest memories from that period is when Anders’ wife, Natalie Sachs-Ericsson, very kindly took me on a shopping trip to buy carpet for my new office in the old Psychology Building. Another early memory is my daughter, Isabel, who was 2 at the time, being presented with a toy animal, a lamb, from Natalie and Anders when they came to visit. That lamb is still in my house. 

Anders’ office was in the Kellogg Research Building next to the Psychology building. The two buildings were connected by a bridge and I have fond memories of standing on that bridge discussing science with Anders, while he smoked a cigarette and we looked at the Spanish-moss covered live oak and the trucks arriving to deliver test animals for our neuroscience colleagues. Although Anders spoke near-perfect English, he maintained a slight Swedish lilt and his sentences were liberally sprinkled with the adverbs essentially and basically, which I suspected were strategic devices deployed to give him more time to think about what to say next.

Years later, we would still be standing on that bridge. Anders had quit smoking at this point, but as soon as we approached the bridge, his hand would still go to his breast pocket, reaching for cigarettes that no longer were there. But his zest for discussion had not left him along with his smoking habit, so we still spent much time debating science topics. On one occasion, I remember being so engrossed in the conversation that I forgot I had to teach a class. I had no time to go back to my office because the students were already waiting and so had to go in empty-handed, much to Anders’ amusement. This was fun! Anders yelled after me, as I rushed off to my students.

We would often leave the bridge to go into the Psychology Building to get coffee. At the door of the psychology building, a strange ritual would invariably unfold, in which Anders and I tried to out-polite one another. After you, one us us would say. No after you, the other would say, a back-and-forth that often lasted for half a minute or so. In the end, I think we were both polite enough to play it to a draw. I probably “won” about as many times by letting him go first as I “lost” by letting him let me go first. We both enjoyed this game, maybe because it reminded us of our common European roots. 

To state that Anders loved to discuss is to understate things. He typically went on the offence and questioned the theoretical justification for your hypothesis or your use of a particular method. Every cognitive psychology colloquium speaker would be subjected to an interrogation by Anders on why they were using their method of choice and not verbal protocols. Wouldn’t you want to know what the people in your experiments are actually thinking? I remember him asking on more than one occasion. It usually left the guest speaker struggling for an answer.

Anders had an interesting style of mentoring a junior colleague. One year into my tenure track he said that it was all fine and good to have empirical papers, but if one wanted to get tenure, one needed a paper in Psychological Review or Psychological Bulletin. I could see his point on some abstract level, but as it pertained to me, I thought it would be a big risk. Writing such a paper would take a lot of time, time that could be spent on more empirical papers, and what if neither of these journals would accept my manuscript? What would be my alternative outlets? I couldn't think of any. 

For a moment it felt as if, on my ladder toward tenure, someone just had taken out a few rungs above me. On the other hand, it was very motivating that someone like Anders would think I was up to the challenge. What particularly convinced me was Anders’ point that you should want to do work that is cited 50 years from now. I set to work and in 1998 my Psych Bulletin paper with Gabe Radvansky appeared. It still is (by far) my most-cited paper and continues to be well cited to this day. We’re not even at the halfway mark of the 50 years Anders had in mind but I will forever remain grateful for the challenge he put in front of me on that bridge.

In our article, Radvansky and I were making use of the notion of long-term working memory, which Anders had developed with Walter Kintsch. I had hoped that this would form the basis for a collaboration with Anders but by then he was well into his expertise research and his focus seemed to have shifted away a little from long-term working memory. Without long-term working memory, finding a connection between research on language comprehension and expertise proved more difficult than I had imagined. 

At some point, Anders and I, still standing on that bridge, had come up with the topic of interpreting, a speaker translating someone else’s speech on the fly. The issue that interested us was how much comprehension would go on in such a task. We had devised an experiment, of the type we both liked: simple, clear, and clever (I think, retrospectively). It involved people translating French into English. The target phrase could only be translated in one of two ways, one of which would indicate comprehension (cross-sentential integration), whereas the other would indicate word-level translation. This would allow us to examine the effect of expertise. An expert interpreter would be able to integrate information across sentences, and thus comprehend, whereas a novice would have to resort to word-level translation. A graduate student in the French department ran the study. I’m not sure what happened to that study. My best recollection is that when the graduate student moved on, neither Anders nor I felt the study to be sufficiently close to our own interests to further pursue it. It turned out that it was a lot easier for us to stand on a bridge and discuss research than to build a bridge between our interests. 

Anders was a voracious reader, which is part of why it was so much fun to talk to him. He was a true intellectual and a deep thinker and you could talk meaningfully about an astonishing variety of topics with him. As behooves a true intellectual, he would be reading many different things simultaneously. So it was not uncommon to see a book open on his desk on Wolfgang Amadeus Mozart’s family history, an edited volume on sport psychology, a book on Elo-ratings in chess, a book on management, as well as various issues of Psych Review (his journal of choice), and photocopies of countless more articles. The picture of Anders’ office is not an exaggeration. I have seen worse. I remember once coming into his office and thinking he wasn’t there when he suddenly emerged from behind the stacks of books on his desk. He was probably writing another Psych Review article. I joked that if he went on like that we’d have to call a rescue team to excavate him from his office. His response was that, indeed, maybe he’d gotten carried away a little.

As much as Anders enjoyed discussions, so little did he care for small talk. In fact, he tried to turn small talk into a more meaningful discussion at the first opportunity he saw. I remember one such case. By then I was head of the CBS (Cognitive, Behavioral, and Social Psychology) area and we were assembling before a meeting. Anders and I had already arrived. Momentarily forgetting who my conversation partner was, I mentioned, just to shoot the breeze, a newspaper article I’d read that morning about intelligent behavior by an octopus. Before I realized it, Anders saw an opening and said something to the effect of In what way do you consider this behavior to be intelligent? Explain yourself, Sir!. The response I had been looking for was more along the lines of Golly, how ‘bout them octopuses! What will they be up to next? I was relieved to see the other members of the area file in, so that we could start the meeting instead of me having to jump into the breach for the intellectual prowess of cephalopods.

At the same time Anders' desire for conversations to be meaningful was what I, and many others, liked so much about him. It made every conversation with him more draining and formal than you might like at times, yes, but he always spoke with enthusiasm, humor, and a twinkle in his bright blue eyes, as Neil put it in his in memoriam (he forgot to mention the wiggling eyebrows), Just like his bow, Anders’ conversational style was both quaint and endearing. He told me that someone once had tried to call him “Andy.” We had a good laugh about this. Anders was definitely not an Andy! After all, an Andy would have said How ‘bout them octopuses! 

Although Anders was Anders not an Andy, he didn't seem to want to move back to Sweden either. I once asked him directly about this. His response was that his focus on his work was so strong that he could live anywhere, as long as he was able do his work. I believed him. I was less single-minded about my work and did feel the pull of my home country. I moved back to the Netherlands in 2007 but I have very warm memories of my13 years in Tallahassee as Anders' colleague.

I was very sad to learn about his passing last week. Only a few weeks ago, I had recommended his book with Herbert Simon on protocol analysis to one of my graduate students. It is now cited in a manuscript that we are about to submit. I like to think that Anders would have liked some of the experiments in it, as they are somewhat similar to the the experiment on interpreting he and I designed all these years ago.

I conclude with some characteristics of Anders as I observed them that are worth emulating. I’m not calling them things I learned from Anders, as I cannot claim to have mastered any of them. 

Read and think broadly and deeply. In Anders’ way of thinking, relevant information about a topic can come from disparate sources but to see and articulate their relevance, you had to think deeply. Your work would be so much the better for it. He did not have much time for researchers who only use a single method and can see the world only through the lens of that method.

Only conduct an experiment when you have thought everything through and you are convinced that: (1) the question is worth asking and (2) the experiment is the best way to answer that question. I heard that Anders used to tell his graduate students that they had to convince him of the experiment’s worth before they were allowed into the lab. In a publish-or-perish culture, this is bound to be frustrating, but imagine the state of the field if every advisor had taken Anders’ approach!

Go for the biggest effect! This was something Anders ad learned from his time with Herb Simon, as he always pointed out. Again, imagine the state of the field if every advisor had followed Anders’ approach!

Be curious about what the participants in your experiments are actually thinking! You can have them press buttons, measure their eye movements, or record their brain activation but in many cases it might be more informative to get at their thought processes more directly. I am becoming more and more convinced of the wisdom of this myself.

Do work that will be cited 50 years from now. Don’t waste your time on smaller projects or administrative duties. And hide behind a wall of books if they come looking for you.

Always raise the bar, not just for others but also for yourself. Anders was relentless on this score, no doubt inspired by his research on expertise. His usual approach was to ask: What would be the best way to accomplish this or that? He would then go on to ask Who are the best people you can think of in this area?. Next, he would ask What are they doing that you are not doing?, followed by How can you start doing what they are doing?. Most researchers lack Anders’ fortitude of mind and will to do this relentlessly, but it is a mindset worth aspiring to.
