Cogito ergo sum. Thus spake René Descartes, usually translated into English as “I think, therefore I am.” Thinking is what makes us human—quite literally so because homo sapiens means “wise man”. So what does it mean to think, let alone to be wise? Much debate can be had about that question, but it seems safe […]
Working Memory
Asking your waiter what beers are on tap should come with a trigger warning, because the simple question may trigger a cognitive challenge. From Heineken to Becks and some other local boutique IPAs whose names you cannot even pronounce, the list can be so extensive that you are put into frantic rehearsal mode just to […]
“Working memory” is a broad term that describes what we do with information that is consciously accessible. For instance, when students take notes in class, they are hearing the lecturer’s sentences, placing them in the context of what they know about the topic, and synthesizing both to form the note they ultimately write on the […]
Few areas of psychology research are as controversial as ‘brain training’. For the last 10 years, we have seen an influx of apps and games that purport to improve users’ cognitive capabilities. The appeal is simple. Play a game, get smarter. The controversy, as we’ve covered here, is that unbiased research on whether brain training […]
You are in the cognitive laboratory and you focus on the screen in front of you. A few color patches are flashed for 1/10th of a second, and 2 seconds later another array of patches appears that stays on the screen until you respond. Your task is to decide whether any one of the patches […]
Throughout most of my career, I think I was aware that there was some issue with the definition of working memory (WM), in that many psychological researchers often seemed to confuse the term WM with the multicomponent model of it that was proposed by Baddeley and Hitch in 1974. I started to go on a […]
In his recent article in the Psychonomic Bulletin & Review that stimulated this digital event, Nelson Cowan undertakes the impressive endeavor to disentangle the various definitions of working memory (WM) that have been around in the literature since the term WM was coined. He does so to counter the confusion that the use of different […]
I was sitting in the audience, listening to a symposium speaker field questions, when someone asked about working memory. “Working memory? Does anyone actually believe in that anymore?” was the speaker’s reply, and from the inside of my narrowly-focused scientific bubble, it astonished me. I had only recently taken up my first tenure-track position as […]
Nelson Cowan’s review of definitions of “working memory” provides a very useful overview of the different ways in which the term has been and is still being used in the literature, and the potential confusion that can be caused by its multi-faceted meaning. Cowan identified nine definitions spanning multiple disciplines and several decades of research, […]
Type “working memory” into Google Scholar and you get nearly 2,000,000 results. Topping the list is the paper “working memory” by Alan Baddeley and Graham Hitch, which has been cited more than 12,000 times since its publication in 1974. The Web of Science search engine is slightly more modest, with around 54,000 scientific publications being […]
