Thank you so much for your presentation! As you studied human recall memory and let the participants draw the images they remembered. I am considering that this may lead to some bias because people would have different preferences towards different realms. They may be impressed by the images that match their preferences. How do you deal with that bias?

[SixueLiu96]

Thanks a lot for your presentation! This is very interesting work! In your study, the participants in the image drawing experiment will definitely have some influence on the results. I wonder how you choose the demographics of participants in this study?

[Anqi-Zhou]

Thank you for your interesting work and presentation in advance. Have you thought about any ways to improve the accuracy, could you please share some ideas with us?

[keertanavc]

Very interesting research. My question is not directly pertaining to the paper but it is something I am curious about - photographic memory. Does this really exist? If it does, then what are the key characteristics that distinguish it from 'normal' memory? Also, is it an acquired trait or is it a genetic trait? Looking forward to your talk tomorrow!

Thanks for your presentation. I'm wondering whether the decay of memory over time will bring about additional variability to the results given that the duration of the recall phase is nontrivial. For example, the free recall phase in the delayed recall experiment took 19min on average. It is very possible that the memory held by subjects is fresh when they work on the drawing of the first picture, but such memory would become blurry to a great extent after 19 mins when they are drawing the last picture. So is it necessary to tease apart such an effect of memory decay?

[Yiqing-Zh]

Thank you for your presentation in advance. It is really an interesting and innovative research topic. I am wondering about how to define the information one could draw from the image and how to measure the error?

[adarshmathew]

Thank you for your presentation, Prof. Bainbridge. This is incredibly interesting research.

As someone who hasn't read any work in psychology, I'm curious about the graph-based visual saliency (GBVS) algorithm, and the Meaning Maps model. I hope you elaborate on these methods in your talk.

My secondary questions have more to do with the implications of your research. Let's take the example of procedures like legal testimony which rely on precise recall of past settings. Would you advise a practitioner to not place a lot of weight on eye-witness testimony given the likelihood of inaccuracy? How do you think additional factors like trauma might affect memory formation and recall process?

[luyingjiang]

Thank you for your presentation. I am really impressed by the results of four experiments and algorithms for GBVS and Meaning Maps. I'm wondering how you deal with the bias that some people may be more sensitive to some images? What is the criterion for selecting the participants (e.g. people from similar age groups, sex, received memory training or not)?

[lyl010]

Thanks for your presentation! Your experiment is very interesting! I am wondering does the result suggest we use different areas of brain to recognize and recall images? Can we use the brain scanning machine to visually depict the difference between the function of brain when we recognize and recall to prove that they are irrelevant to each other? Because I assume that, which might not be correct, brain scanning may be more direct than indirect drawing, and I think there might be some differences and I am wondering what them are. Thank you again!

[luxin-tian]

Thank you for your presentation. I was wondering if the varying drawing capacities of the participants would result in potential problems when evaluating and quantifying the memory recall performance? How would you address this issue, if any?

[jsgenan]

Thank you for bringing us the frontier research of memory. And it is my first time reading a visual saliency map. Could you comment on the advantages and potentials of this technology?

[JuneZzj]

Thank you for presenting. It is good to know that the memory depends on the prior knowledge people have. I am also wondering that if people have propensity to memorize what they see based on what they think is important. The prior knowledge may somehow determines what they tend to focus on. Thank you.

[sanittawan]

Thank you for sharing your research with us. This's one of the first papers I have read on research on memory. Could you please elaborate on the setup of the experiment and provide an intuition how you and your co-authors control for other differences that could potentially affect the results, for example, the level of drawing skills, level of attention the participants paid to the first vs the last images? How do you make sure that the variety of results that we observed is from the intended manipulation (like delayed recall, immediate recall etc.)?

[ziwnchen]

Thanks for the interesting research about spatial cognition! One thing this paper remind me immediately is how similar the visual saliency is to the current "attention"/image captioning research in computer vision. Is it possible that findings in this research be incorporated to research in computer vision? How memory-based drawing is able to inform us of the way humans perceiving space and how is that different from the computer algorithm?

[goldengua]

This is a very interesting study and points out free drawing as a potential measure for future research. I have a question about the digit span task before the free recall phase. In my understanding, the digit span task was used to prolong the time between memorising and recalling, and also ensure participates are not using verbal working memory. I was wondering if it would make a difference to let the participants verbally recite some lexical items. Maybe participants have seperate verbal working memory for numbers and concrete objects in pictures. Memorising numbers would not interfere free recall at the later stage as much as memorising concrete lexical items.

[Yawei-Li]

Thank you for sharing your research with us at this moment. I am not very familiar with memory and have seldomly read papers in this field, and your research would really open up my knowledge. It is truly an inspiration that how can computational techniques be used in your topic.

[cytwill]

Thank you for sharing this interesting topic, I have some similar issues with @wanitchayap. Compared to 2D stimulus, can we employ the same analytical ideas for 3D stimulus? Besides, a small question is how to filter data collected by AMT workers who are not so accurate in drawing?

[yalingtsui]

Thank you for your presentation! Very interesting work. I wonder if there exist some way to improve the human beings memory based on your research.

[yongfeilu]

Thank you very much for the presentation! It's amazing to see how much great work you have done to reach the conclusion. But what puzzles me somehow is that the conclusion is a bit intuitive. Could you please tell us a bit more about the implication of your research? Thank you very much!

[policyglot]

Dr Bainbridge, You mentioned on Pg 6 how spatial memory was accurate in the given task. What research would you recommend to explore how an individual's location while performing an action can become an anchor for other non-spatial information? Thank you!

[hesongrun]

Thanks a lot for your presentation! The topic of memory is really fascinating. Based on your findings, are there any methods to convert non-spatial information to spatial information to enhance memory? Like construct a map or building inside your brain to consolidate the knowledge learnt. Thanks!

[ellenhsieh]

Thank you for presenting such interesting paper! In the paper, we can see that in each scenario we are comparing four different drawing methods: 1) delayed recall, 2) immediate recall, 3) image drawing, and 4) category drawing. I am particularly interested in why the category drawing is needed to compare in this study since category drawing seems to just draw the picture based on our knowledge or imagination of specific category. Would you mind to elaborate more on "category drawing" in this study?

[wu-yt]

Thank you so much for presenting such an interesting paper! I’m wondering what are some of the implications and applications of your results in the real world and how it can combine with the current technology?

[YanjieZhou]

Thank you so much for your presentation! The research is based on spatial memory, but the accuracy of it, in my opinion, still remains a problem. Can you think of some possible methods that may combine neuroscience and spatial cognition to solve this problem?

[anuraag94]

Thank your for sharing your research with us. I'm interested in the application of this research to the visualization design. For example, (Healey & Ens, 2011) touch on how recent findings in visual memory can be applied to computer graphics. Very interested in your thoughts on this.

[vinsonyz]

Thanks for you presentation! It's my first time to know the research of spatial memory. I am wondering how this research method could be applied to economics or more specifically behavioral economics?
