This is (related to) a very old idea: https://en.wikipedia.org/wiki/Method_of_loci

I noticed I also recall conversations, podcasts etc better if I was doing some kind of a manual task at the same time (like woodcarving, or just doing the dishes). My interpretation is that focusing on a conversation while immobile is under-stimulating, and thus causes the mind to wander. If one is walking, or doing something physical, its enough physical stimulation to let the mind focus on the conversation in a "railroaded" fashion, without self-distraction.

Even deeper: it feels great to match your walking/activity pace to the emotional message of the conversation. I suppose it triggers the same reaction as ASMR. I suppose its because it lets us "act out" our emotional reaction to the words, without inappropriate gesticulation etc.

Further weak evidence that walking helps with conversational cognition:

- plenty of people, without any cultural connection between them, pick up the habit of pacing around when on the phone. 

- it was a well known technique among ancient Greek philosophers and scholars to just take their students on a walk, or even a longer trip while discussing abstract subjects. Apparently it worked very well and was done this way for centuries.

- humans evolved to be semi-nomadic persistence hunters. Walking around all day is our natural state that we evolved for, sitting down for hours is not.

My brain also associates memories with locations, and I've noticed I do have the exact same location-based recall in full VR as I do in real life.

Thinking back, most of the main points I can recall from conversations in VR are either when I have just moved around the virtual space (so the visuals are different), or when new people come into the conversation (especially people with interesting avatars).

Interesting. I'd be interested in seeing if this works for others too.

Another idea: closing ones eyes while one talks (or voice chats), just to see how it effects memory.

Anecdotal evidence, I have heard from many people that they associate conversations with where they had them. Use the :thumbs-up: react if you also heard this.

Some small experiments related to this effect. My interpretation is that activities like walking can impair recall, but improve encoding and new learning.

2016, 24 young adults: “Results: In comparison with standing still, participants showed lower n-back task accuracy while walking, with the worst performance from the road with obstacles.”

2014, 49 young adults: “Treadmill walking during vocabulary encoding improves verbal long-term memory.”

2014, 20 young adults: No significant difference in a spatial working memory task for any walk speed, including standing still.

2021, 11 people with MS-related impairments in new learning: Moderate to large improvement in a verbal learning task.

2011, 80 college students: “ Walking before study enhances free recall but not judgement-of-learning magnitude.”

There is also some evidence of general-purpose cognitive benefits to walking.  Reposting a comment [LW(p) · GW(p)] below:

There have been studies on the subject, having people walk or not (and walk in varying conditions) and measuring their performance on some intellectual or creative task, and concluding that (a) walking does help and (b) the type of walk probably matters.  First citation I found: https://www.apa.org/pubs/journals/releases/xlm-a0036577.pdf

Four experiments demonstrate that walking boosts creative ideation in real time and shortly after. In Experiment 1, while seated and then when walking on a treadmill, adults completed Guilford’s alternate uses (GAU) test of creative divergent thinking and the compound remote associates (CRA) test of convergent thinking. Walking increased 81% of participants’ creativity on the GAU, but only increased 23% of participants’ scores for the CRA. In Experiment 2, participants completed the GAU when seated and then walking, when walking and then seated, or when seated twice. Again, walking led to higher GAU scores. Moreover, when seated after walking, participants exhibited a residual creative boost. Experiment 3 generalized the prior effects to outdoor walking. Experiment 4 tested the effect of walking on creative analogy generation. Participants sat inside, walked on a treadmill inside, walked outside, or were rolled outside in a wheelchair. Walking outside produced the most novel and highest quality analogies. The effects of outdoor stimulation and walking were separable. Walking opens up the free flow of ideas, and it is a simple and robust solution to the goals of increasing creativity and increasing physical activity.

I would be interested to see if it helps to be familiar with the space you are walking in. If not, you could for example generate a new MineCraft world for every episode of a podcast. Then name that world as the podcast name just in case.

It could possibly be more effective to travel through google maps. Doing this would lead to clearer landmarks to anchor to.

Or, there are many ambient walking/driving videos on YouTube. Would watching one of these have the same effect? I have doubts. I remember as a child watching the road as my Mother drove me to school every day. But when it came time for me to finally drive I could only vaguely get the route. A similar thing happens when I'm following someone else's directions as I walk with them.

Ideally you would just walk. Exercise and learning at the same time is wonderful. But, you'll exhaust the possible directions you can travel in eventually. I use my daily walking route as a mind palace to place characters in at predetermined landmarks. I then give each a corresponding number. It's taking a while, but eventually the goal is to use this to remember stats and dates.

This is a good suggestion! I'll plan on walking in addition to talking during my upcoming meetup [? · GW].
