I have a lot of questions to think about on this topic. For example, how do I present songs and playlists from a streaming platform during my lab experiments or online? How do I legally record the use of these songs and how do I factor this into my data sharing plan?

This topic is new to me. I would like to know more about how I can assign licenses to materials that I may develop during research.

In research with children and adolescents, in addition to registering the consent of their parents/caregivers, it is also essential to explain the research to the children and guarantee the registration of the consent of these participants.

Regarding ethics, I would like to know more about studying eyetracking in populations with atypical development. I would like to know more about examples of conflict situations and how to deal with them. If possible, please comment on the eligibility and exclusion criteria adopted in the research with eye tracking.

Guilherme Delmolin made a comment
Yes! I think that the biggest challenges are related to ethical conduct regarding the security of the registered information.

I don't think I have a trick, but a way of thinking about the many different ways that data can be lost. I have backups, at least 2 in the cloud and a backup on the machine I'm working on.

This discussion is fundamental in research training. I think it's very good to have a week dedicated to this topic.

I was very excited to hear about the experiments being conducted with the orchestra.
I would like to share a short video of a scientific communication activity that we carried out in 2017 with my city's orchestra to demonstrate neuroscientific investigation techniques to the audience. In the video, one of the pianists (on the right) uses near-infrared...

I enjoyed many of the studies reported here! I was wondering about the uses of pupillometry in investigating individual differences in cross-cultural studies and came across this study. Here, no differences were found in pupil measures on a prosocial attention task between German and Kenyan...
-
Guilherme Delmolin made a comment
Watching the video, I was reminded of this paper - I think it was presented earlier in this course - which describes changes in the pupil associated with working memory capacity. I kept thinking about how important it is to replicate studies like this and extend the findings to other skills and/or cognitive...

The methods applied to regain the child's attention and to locate her face are very interesting.

I'm always torn between Money and Superstition, and that makes me think again about cultural influences and our musical preferences. For me, playing Money on bass can be as "Groovier" as playing Superstition or Yesterday.

Guilherme Delmolin replied to Doug Karo
So there seems to be an important gap to replicate these results in other cultures. What do you think of that, Connor?

Guilherme Delmolin made a comment
I had the experience of collecting data in a real situation (outside the laboratory) using eyetracking in a classroom with children from 7 to 12 years old. It is really challenging to ask children to keep their heads still while reading lists of words on a computer lol.
-
@ConnorSpiech Thanks for sharing, Connor. I see myself doing the same as you with the data I'm working on at the moment, I'll start by replicating the Jamovi reports in R. :)

Guilherme Delmolin made a comment
I loved reading the paper that I imagine is related to this study! :)

The lessons this week were great! For me, it was very relevant to read about building experiments, facing artifacts, and controlling for baselines.
-
Guilherme Delmolin made a comment
I would like to get any suggestions on courses for starting learners in R who already knows how to use SPSS, Jamovi, and JASP.
-
I'm thinking the same thing. I think most experiments that evaluate mental effort should have control for the baseline of each attempt at a task. Right? Are there examples of different situations where the baseline is not relevant?
-
Guilherme Delmolin made a comment
I would like to read more about methodological approaches for building experiments using audio/music. After reading this section I started thinking more about how to get the baseline for different conditions (e.g. audio x audiovisual x visual).
-
Guilherme Delmolin replied to Scott Leimroth
Thinking about experiments using music/audio clips, the baseline could be recorded using both quiet conditions and non-task-related audio, depending on the research question.
-
Guilherme Delmolin made a comment
I actually worked with both. Mobile as a researcher and stationary as a participant in a pilot.
-
Guilherme Delmolin made a comment
I am currently thinking of assessing cognitive effort on tasks involving executive functioning, with both visual and auditory stimuli. I believe the measures demonstrated by Connor are more appropriate since they record the onset of pupillary responses in a tiny time window (milliseconds).
However, I am also considering using auditory tasks that have a...

After this class, I am considering using fixed eye-tracking equipment because of its greater accuracy in pupil diameter measurements. Then integrating with calibration techniques and using tasks with visual and auditory (musical) stimuli, I think it might be interesting to apply pupillometry to try to replicate the results of Meher et. al (2022) accounting for...

I would like to know about the desirable skills in programming that we need to master to combine motion capture and eye tracking in naturalistic experiments. Having a background in Cognitive Psychology I think it is very important to look for continuous improvement of desirable skills in interdisciplinary settings.
-
Reading this report, I think it would be really interesting to have eye-tracker equipment in the palm of your hand during experimental psychology classes or distance learning courses like this one. Imagine with all of us could open the camera app and record changes in our students' diameters while solving multiplication problems (!).
As I think more about...

I would like to read more about methods and paradigms in cognitive sciences using eye-tracking systems. Seems to me that there is a lot of experimentation and novelty with the design of experiments and ways to analyze behavioral and eye-tracking data.
-
Guilherme Delmolin made a comment
Initially, I would like to assess changes in mental effort and/or performance on cognitive tasks via pupillometry paradigms. In the second step, I would like to assess individual variability in cognitive and musical tasks as well as demographic data (musical sophistication, age, for example).
-
Guilherme Delmolin made a comment
In addition to Scott's excellent summary, I'm thinking about how pupillometry could be used to evaluate surprises in music or any other kind of surprise (hearing a joke for example) in a naturalistic context.
Would it be possible to measure changes in the pupil of musicians as they play together and associate the musical changes with experiences of surprise? -
Guilherme Delmolin made a comment
1) I am currently evaluating the possibility of using pupillometry techniques in conjunction with TMS techniques. I wonder if transcranial stimulation paradigms could be useful in assessing causality between increased mental effort and observed changes in pupil dilation. For example, evaluate how disruption of connectivity between executive cortical areas...

I recruited my girlfriend for this experiment (I couldn't self-assess). While trying to evaluate changes in her pupil dilation I noticed a lot of movement and blinking.

The first movie that comes to my mind was Clockwork Orange, but I know that psychology methods today are much less invasive rs.
-
Guilherme Delmolin made a comment
I am coming a little late to this session of the course, however, I have had a chance to read all the thoughtful questions asked here.
My question would be: What are the main challenges researchers face in using pupillometry today?
-
@JudithLowes Very interesting!

Hello everyone! I am a PhD student from Brazil and I am studying musicality and executive functioning in the graduate program in neuroscience and cognition at the Federal University of ABC.
I've already worked with eyetrackers during my masters helping other colleagues to setup and collect data in places like classrooms, a theatre and the lab.
I want to...

I would like to learn about the history of the development of this technique.

Guilherme Delmolin made a comment
I did have to try harder to stay still listening to Mozart's parts. The notes about his impressions helped me a lot to understand or to try to transport myself to that moment. However, the main difference noted was about the tempo and dynamics of the orchestra technique.
While listening to Herbie and Pat this exercise was more interesting. It was harder to... -
Watching this video I cannot stop thinking about babies moving around while listening to joyful sounds.
I would like to know more about Professor Jensenius work. Did they explore how these little and fast movements develop through different ages? -
Hi everyone. I'm very interested in this course because I'm a Musician and also a Psychologist from Brazil. Right now I'm teaching classes about Experimental and Neuropsychology at a local University and looking forward to starting a Ph.D. program in the field of Neurosciences. Also, I'm a collaborator at the project Neuroscience and Music at Universidade...
