Work hard, play harder. As a Python girly/data sci person i am so upset with psychtoolbox lmao. Yes, my 5 years of matlab in engineering prepares me for this, but WOW the compatibitlity issues just hurt. I might switch to psychopy, idk idk.

Anyways, went for a weekend beach trip with bae in Portugal and it was absolutely the refresh I needed to get back to this grind. The ocean always makes me feel small and grateful to exist and I am reminded that I am doing a really challenging and difficult thing and that mistakes are part of it, learning is part of it, doing badly is part of it. My daily reminder right now is: it’s not about how fast I do things, but how well I do them.

ResChat @Resplat: Using MATLAB, R and Qualtrics to examine cognitive and behavioural science of Pokies reform.

What is your PhD researching? 

I am researching how design elements of the pokies may contribute to harmful gambling behaviour. Broadly, I also have an interest in how cognitive and behavioural sciences can inform public policy to improve quality of life or reduce harm.

For the most part my PhD focusses on a single aspect of Pokie machine design that researchers have called ‘losses disguised as wins’. These events occur when a machine returns a small payout that is less than the original bet. Financially speaking, these events are actually a loss, but the machines celebrate these events just like wins (i.e., with sounds and lights). So it’s likely that these events might make gambling feel more rewarding than it is financially.

So we're looking at that in a few different ways. Firstly we are running an EEG study, where we record a signal that can be used to index the brain's response to positive and negative outcomes. We’re analysing whether we're processing these losses more like wins rather than like losses. We're also doing an eye tracking study, where we teach some players spot whether a win is genuine or a loss disguised as win. We can then measure their eye-movements to check whether they engage with the visual feedback on the machine to check that they are doing the calculation necessary to tell the difference. When we make small mental calculations the pupil dilates, so we can also use pupil size to check that a calculation is taking place.

The last component of my PhD is a social attitudes survey. We want to know what happens when we tell the general public about about these particular pokies features, whether that changes their disposition towards harm minimisation policy in the sector, or whether it increases or decreases stigma towards people who engage in pokies gambling.

Can you tell me more about the tools you are using in your research?  

I have been putting my survey together using Qualtrics, which is an easy web based survey design platform. I plan to do all my analyses using R & R Studio, specifically the Tidy Verse package, which I've been learning with ResPlat. After getting involved with ResPlat I’m pretty comfortable cleaning data and using Tidy Verse in R to set everything up nicely, but I haven't done any of my analyses yet because I'm still collecting data!

For the EEG data,. there's an open source MATLAB package called EEG Lab and ERP Lab which is used to analyse EEG data. I'll also be using Psych toolbox, which is another toolbox written for MATLAB to present stimuli to participants, so I'm rapidly trying to learn MATLAB this year!!

Would you recommend our services to other Graduate Researchers?  Absolutely, I think that the ResPlat service is great. There are two things that you guys do really well. The first is, I think, often, at least the first challenge when you want to learn a new tool, is you don't know where to start. In response to that your introductory courses are great as they can get you up to speed with the basic operations & fundamentals of the tool for research. If you were to try to teach yourself that alone on the internet, although resources are getting better, you don't know what to search for and you don't know what's important to learn first. With the courses you put training wheels on and it allows you to gain all the basic knowledge you need to start answering your own questions. 

Another thing you guys do really well is build a community of researchers. I like learning socially and I find that a good test of your knowledge is to try explain it to someone else and help them troubleshoot. Almost immediately after finishing the Introduction to R workshop, I started coming along and helping out. Through this you become connected with other researchers who are learning, so you can problem solve together, which also helps solidify a lot of the knowledge and that builds the research community too.

I don't suppose any of y'all know how to code in psychtoolbox

[chemrxn]

ey girl #3 from your unusual asks just do it and rantttttt

hey bb u just know exactly what i need <3

3. rant. just do it

uhh so it’s been 5 months since i joined my current lab and i’ve felt huge amounts of imposter syndrome since day one? (it literally took me like 4 of those months to actually have a proper conversation with my PI since i mostly talk to my grad student. also my PI intimidates me even though people say she’s really nice.) i barely know any coding and computational neuro still - i’ve only just started to figure out MATLAB and Psychtoolbox even though i told myself to learn it asap. also i can’t help but feel like my grad student is doing a lot of handholding and is essentially my research babysitter bc i don’t know enough to do stuff on my own!! tomorrow is our summer research symposium and i don’t think i can properly explain everything in our study. heck, i’ve even forgotten basic brain anatomy, which makes me feel stupid when my grad student asks me questions about it. i’m a neuro major and i don’t know basic brain facts!! 

i wonder if i’ll ever stop feeling this way, because already this imposter syndrome has prevented me from asking for money over the summer (a BIG L), and it’s definitely preventing me from talking to my PI about doing a thesis. don’t get me wrong, i don’t hate being in this lab - people are super nice and the work i’m doing is super interesting!! but i’m getting tired. 

also i’m supposed to be studying for the mcat but i’m so behind. i don’t know anything and i’m fucked!! but i don’t have the energy to study when i get home!!

This is useful if you are developing code. This window behaves much like a standard application window in that it can be moved around with the mouse etc.

Online stereogram reader full#

This is useful if you are developing code on a single monitor setup as it means if your code crashes, you are not stuck with a full PTB window covering your whole screen.įloating Window Demo: This demo demostrates is similat to Partial Window Demo, but it creates a PTB window with a window bar and standard window buttons.

Online stereogram reader how to#

Partial Window Demo: This demo demostrates how to create a PTB window which covers only part of the screen.

Online stereogram reader update#

For example, you might want to update the stimulus every second, rather then at the frame rate of your monitor, as in " Accurate Timing Demo". Wait Frames Demo: Here we demonstrate how to update an image on the screen at a rate different to that of the monitors refresh rate. For presenting a stimulus which is unchanging, or changes less frequently then each frame, see the next demo. Please read the extensive comments in the demo closely, they are important and should not be ignored. The three ways demonstrate varying degrees of potential accuracy. This demos how to get pretty much all the basic info you will need about the screen.Īccurate Timing Demo: This demo shows three basic ways in which to present a stimulus which would change on each frame. Totally Minimal Demo #2: This is the same as " Totally Minimal Demo", except after opening the window we query numerous things about it. But it demonstrates pretty much the steps you will always use when starting a program i.e. Totally Minimal Demo: This demo aims to be as minimal as possible. Therefore, if you have never programmed with PTB, start here. If you look at the later demos you will see that virtually all of the core code is shared with these early demos. As such, this first set of demos starts with the complete basics to introduce you to the core principles that constitute the foundations for all that follows. The aim of the tutorials is to assume no prior experiance of programming with PTB.

Online stereogram reader windows#

PTB is now primary developed for Linux, reduced functionality and support is provided for Windows and OSXĬOMING SOON: Matlab and Psychtoolbox YouTube course and Psychtoolbox Demos paper for citing this resource If you have problems with core PTB functionality ask questions there. PTB has an active forum which can be found here. It is not however good practice for running code in an experiment, as having a seperate screen for the Matlab interface will negatively impact timing. This is also good practice for the development of code, where the code might crash during development. As such, if you have only one monitor this will cover your entire viewable screen. It is strongly suggested that you have a secondary monitor connected to your computer when exploring the demos, as nearly all of the demos will open a full screen window. I provide no guarantees that the demos provide "best practice" for your specific needs. Please make sure you carefully read the comments in the code as these provide an explanation of why things are done the way they are. The demos provided as an educational resource. If you are not clear on the essentials, you will struggle with the more difficult aspects. For all users I strongly suggest looking at sections (1) and (2) as these show essential features which will help get you up to speed coding in Matlab and PTB. There are around 80 demos on this site and these are organised into sections based on learning different aspects of PTB. If you have previously installed PTB I recommend you use the "UpdatePsychtoolbox" command to get the latest version.

Online stereogram reader install#

To get started you will need to have installed Matlab or Octave (a free clone version of Matlab) and followed the install instructions which are provided on the PTB website. The aim of these demos is to provide an introduction to how to program using Psychtoolbox (PTB). To access the old version of the page with all of the code links (but no images and movies) please click here. As such, until I have worked my way through all the demos (hopefully over the next week), there will be missing pages and links for a while, and also some formatting issues. What you see here is the new website page. August 27th 2022: I am currently updating all of the demos and tutorials on the website so that each demo has a seperate webpage with embeded media.

So it turns out my group is wonderful and they don't think I was slacking [and I hid my abject panic well] and they are super sweet, so one of them is offering to go over the code with me at some other point object by object so that I really, really know what's going on.

And first I will work through this tutorial so I'm not going to be ridiculous anymore.
