How many mistakes are we allowed to have in the exam?
i think its 12
hi, can the methods of adjustment,limits and constant stimuli be used to detct the absolute threshold and the difference threshold?
yes, these are all the classical psychophysical methods and can be used to measure both! See Goldstein Ch.1 p 14 (9th edition) in the abstract before "estimating magnitude"
Thank you

Hello. For question 22 I got b as my answer. If it is c can you maybe explain it? :)
oh yeah true. forgot that it was about the incorrect answer?

Hey, the condition in which you cannot reach for objects (lesion in dorsal pathway) is called optic ATAXIA (not agnosia), isn't it?
Hey, I just checked and you're right, in this case its ataxia although agnosia can also be due to damage to posterior region (and also to temporal and occipital region). Thanks for pointing it out!

Just a note, with the specialized brain areas, you made a typo: visual world form area instead of visual word form area.

Hi, thank you! do you have the answers aswell?
Unfortunately not, i think if you submit your answers on the student portal you will get feedback. Once I have done that i will upload the answers :)

Would it be possible for you to upload the document in a word format? :-)
Okay, I will!!
thank you so much!!
how did you guys think the exam went? and are the answer keys not up today? :)
The answer key is online already!
thank you for the reply! :)
It's supposed to say "photon". Whoopsie

Hey :) Any helpful tips for the exam? What should we focus on? How important are the E-readers, do we need to know the methods in detail? Thanks!
I took the exam last year. It's one of the easier exams, so don't worry too much. Most important is understanding a few key concepts and terms per task. I think the course coordinators do a good job at pointing out what you have to know. If you have any questions pertaining to whether something is relevant or need an additional explanation, I might be able to help out.
It was one of the best courses! The exam is the fairest I think and if you do the practical exam on Eleum, everything will be fine :)

Great work my friend! Short question, how do you makes those? Like which program do you use?
Hey, quiet late, I hope you can still use it: https://www.mindmup.com/ this is an awesome tool!!
i used ithoughtsX sorry for the late answer
Can anyone suggest good books or other material for this course? Thank you!
Video on youtube are generally well explained and for sure, good books are matter of appreciation :)
hey people, how did you like the exam? :) i think it was ok, but i'm always bad with guessing so i wonder what you think about it

you serious?
Yeah I agree it was pretty easy. If you got the basic concepts you coul easily get an 8
Illusory contours in vision happen in V1 or V2?
View 2 more comments
real contours is V1
That is not true. In the article with monkeys it said explicitly: Cells in V1 (area 17) were not able to see contours.
Is it correct that we don't need to know the differences between Merkel receptors etc? Only that there are 4 types that respond to different properties?
Never heard of them tbh
No, we don't even need to know the differences between the four receptors (according to the tutor)...
Hey guys! What did they find out in the holway and boring hallway-experiment? (its missing in my notes)
They found out that size estimation gets worse when using visual angle when depth information is not available
One one side of the hallway there was a comparison circle and on the other one a test circle; the participant wasn't able to use depth cues and had to change the size of the comparison circle to match the size of the test circle
Could someone explain auditory masking? What she mentions in the second overview lecture? I'm confused..
View 1 more comment
If for example a friend is talking to you, and suddenly there's a loud noise (the auditory mask) like a car going by, it will sound like the person was still talking (in other words, the talking was a continuous sound) even though that might not necessarily be the case. In a way it's an illusion. You can compare this with the gestalt principle of good continuation = the brain will continue the noise, similar to how it might continue a line in the visual system.
high frequencies can better masked and low worse because low frequencies have a wider spread because they travel longer through the cochlea... at least thats what she said in the lecture
what is the streaming effect again?

At the same pitch difference, a faster tempo will rather induce segregation than fusion
gracias !

I would be interested in hearing how helpful you found this. The thing is, you can collaborate on workflowy, and if you did, one could spend more time on better answers.
it doesn't work
Hm, i've just tried with the person next to me and it functioned --- perhaps its a browser issue ? :(
There was a question about the gestalt laws in the exam questions on the studentportal, i thought that these laws are something like short cuts ( heuristics) and in the most time they work good , but that was the wrong answer :/ can someone maybe explain that again?
View 1 more comment
Well the question is which statement is incorrect, and since Gestalt laws are truly heuristics that mostly work well, choosing this answer as the incorrect statement is false.
ahh ok :D
Helloo, would be much appreciated if someone could tell me what happens in LGN and what in V1, especially which one contains simple complex and end-stop cells? My notes arent clear enough to tell
The complex, end stop and simple cells are only in the cortex :)
can someone maybe post the answer "keys" for the formative tests on eleum? because i did the tests but can't see my results for any of the tests.

* it doesn't work with explorer as well
Hey! You have to go on eleum and you have an icon on the right upper corner with a red notification :)
Could someone explain single and double dissociation related to the pathways? Would really appreciate it!

is that important??
Wikipedia: "If one can demonstrate that a lesion in brain structure A impairs function X but not Y, and further demonstrate that a lesion to brain structure B impairs function Y but spares function X, one can make more specific inferences about brain function and function localization."
Hey! Could someone explan what exactly the fourier analysis is? In my notes it says, that the cochlea ould perform a fourier analysis - but what does that mean? Thanks.
https://www.youtube.com/watch?v=k8FXF1KjzY0 Basically what Fourier Analysis does is> The ear receives input as complex as towards the end of the video (complex tone) and the fourier analysis finds the length of the bars that contribute to it (the frequencies that together make up the complex tone) . Every complex wave is made up of simple waves.
Does anyone have the right answers for the Method and technique questions and is willing to share them with me? :) I am a third year student and i'm not able to participate in the course anymore.. It would be really helpful. Thanks a lot in advance!!

There are 4 questions about this part for the exam, unfortunately :(
Thank you!! And yes, last times there were 2 questions about it in it.
Is it enough to know that V2, V3, V4 etc does more complex processing than the V1, or do we need to know the function of V2, V3... individually?
I'd rather side with the view that "more complex processing" is enough, apart from small knowledge bits. I cant recall having heard too much about V2-V5
Hey friends, my EleUm does not work. Can someone tell me the exact time of tomorrows exam? thanks in advance
13.00 - 15.00 h
merci
What is exactly the what and where pathway?
Samantha, thats incorrect... both go through the thalamus (LGN), then the V1. The "what"/ventral pathway then goes to the temporal lobe, and the "where"/how/dorsal pathway goes to the parietal lobe. Both pathways work together, and send feedback to the V1. Remember dorsal means towards the back/up=parietal. Ventral means towards the chest/down=temporal.
Is anyone else having issues with the recordings? I've got so many blanks from perception lectures that I wanted to go through them but none of them are playing and it says media error? Unless somebody has full lecture notes they wouldn't mind sharing? Specifically for the overviews would be fab!

can you send it also here? I'm having trouble too.. I hate it when it happeneds :(
I can't post it here in the comments so I made a pdf :)
Does someone have a nice explanation for the scale illusion ?
it happens because of the grouping by similarity of pitch. all the low-pitch tones are grouped together and the high-pitch tones are grouped together :) if the first tone your right ear receives is high, all the high tones will be assigned to the right ear and vice versa (first tone low --> all low tones)
It is one melody (of high and low tones) that goes to the right ear and another melody of high + low tones that goes to the other ear. -> your brains receives 2x input and combines it with al high tones in the right ear + low tones in the left ear.
Can someone please explain what Pragnaz means

i.e. you see the Olympic sign as five rings instead of all the small shapes the five rings make up :)
Thank you so much! :)
Regarding the different law's of task 1: did you only speak in detail about the mathematical principle behind Weber? Or also the Weber-Fechner adoption and Steven? Or is it only necessary to understand the meaning of the latter two?
I think the main things we need to know are in the first overview lecture :) and knowing the different formulas (log, exp, ...) with responses compression and response expansion is important :)

Would you happen to have lecture notes for the very last lecture? The recording didn't work :/
I only have the slides from last year lecture, do you want me to upload it?
I have some handwritten notes about the last lecture. Do you want it Annelies?
Does someone has a summary of all the articles?
Unfortunately I only have the last one (more than complete with some useless information ahah) nut some summaries includes the articles :)

Are the answers at the end correct?

I had the course coordinator as tutor and we talked about it and B) is indeed the INCORRECT statement :)
The best to do is to fill in the questionnaires on ileum so you have the right answers :)
Do we need to know about opponent neurons? I see it in some summaries here but it hasn't been discussed in our group
View 2 more comments
Yeah some tutors really don't seem to care or know what we need. Kind of sad that they're there and we can't even trust them
it's definitely important, but basically the same as lateral inhibiton

Is it just me or who else found this exam easy? I didn't make a single mistake and I feel like the real exam is gonna be a lot harder... Do you guys think there will be more detailed questions than this?
same here!
I'm also curious about this: Have you seen other exams? Were they similar to this one? Do you think there will me more difficult/detailled questions?
Is it correct that population coding also exists in the auditory cortex? If so how does it work?

volley principle?????
volley principle means that neurons "take turn" because they have to recover :)
Guys, anyne care to explain the mchanisms of the dress once more? always mix them up =)

If you automatically expect warm illumination the dress appears black & blue. If you expect cold illumination it appears white & gold.
