Great video. it helped me understand a lot. Quick questions about neural activity: 1. What is the difference between neural activity and organisation of perception? Isn't the way the neurones are fired that organises the information ? Or when you say neural activity, you are referring to sensory receptors sending messages to the sensory neurone that delivers that message to the brain to organise? 2. Is the way that neurones are fired that cause initial perception because you mentioned that we can change perception at will? So, I see a stimulus and my neural activity leads to a certain interpretation off the stimulus? Like as a first thought before I really think about what I am sensing?? 3. Can experience and learning change our neural activity? Does that lead to a difference in perception? For example, If I thought the way a piano sounds is similar to a guitar, then through learning, I pick up the true sound of a piano to identify it quicker and faster next time, is that change in perception of a stimulus due to neural activity ?
Great questions, I'll try to address each as best I can: 1. We can think of the neural activity having two main parts, there's the basic activation related to the sensation, then this cascades to other areas (association areas) to help us to interpret the sensation. So in the case of vision, you would have initial stimulation of the V1 visual area in the occipital lobes for the basic information of what you are sensing, then this would spread to other neurons to determine what you are seeing. This leads us to your next question... 2. Some neurons (like feature detectors in V1) will fire in response to basic patterns (lines, angles, shapes, etc) but the patterns of association areas will be more dependent on your experience and interpretation. So for an illusion like a Necker cube, the feature detectors are firing the same way regardless of how you interpret it, but the activity of association areas would differ. With experience some aspects of what the association areas do will be essentially automatic, so you recognize a piano sound without much effort, or you immediately interpret the height of a step on a staircase as soon as you look at it. And this leads us to your last question... 3. Your association areas are built up over years of experience changing your brain in order to help you recognize certain things more readily and this is occurring all the time. So certain shapes, sounds, etc, that are relevant for you will be recognized more quickly and easily, so you can learn to do something like recognize the voice of a new friend. This would be due to changes in your association areas that now recognize a certain pattern of stimulation as that person's voice. Because we usually aren't in completely novel situations, we take perception for granted because it happens almost automatically but we are constantly updating our perception of the world and what certain patterns of stimulation mean for us. I hope these answers help, thanks for commenting!
@@PsychExamReview It's so nice of you to answer all these questions with so many details! I'm a psychology majored student preparing for my mid-term, and this is my first time watching your video. It's so clear and helps me recap everything very quikly. Just subscribed without any hesitation!
Thank you, my students will find this video so helpful to understand a class that I am teaching them, which is about sensation and perception. Good job you did.
Hello! Im doing a research about multi sensory applied in design. Ive seen your video about gestalt theory i think it was vid #55. But im looking for auditory and odor principles. I get that gestalt theory can be applied in both haptic and visual perceptions, i just do not get how it can be applied in odor and auditory perception. Please help me. :(
Hi, I'm not as familiar with odor examples but for auditory examples we can see Gestalt principles like proximity for grouping high and low pitches. You can see this in Diana Deutsch's Mysterious melody illusion, where playing notes far apart in octaves makes it much harder to identify the melody, but when played in the same octave the melody is immediately recognizable: deutsch.ucsd.edu/psychology/pages.php?i=207
This might cause a feeling of confusion, like when you hear a sound but can't identify what it is, or if you look at an image or painting and can't quite figure out what you're looking at right away. The sensation is there but how to properly perceive or interpret it may take a bit longer.
Hey, you teach well. I am soon appearing for postgraduate psych school entrance, I have a hard time reading books . So do you think the material being discussed in these playlists would be enough to get through?
I've tried to make this series comprehensive in covering the major ideas for different areas of psychology. But for graduate level work you would need more specific knowledge and detail within the topic you plan to focus on. I'm hoping to eventually make some advanced-level series for different areas of psychology, starting with research methods and statistics, but I haven't had time to get started on those yet. Thanks for commenting!
@@PsychExamReview appreciate your concern :) But sir, could you please tell me where else I could learn , because as I said I have a hard time going through text in the book. It's too comprehensive , time consuming and hard. Visual learning seems much more effective and self explanatory.
Ur 6 min video is way better than 2 hours lecture of my so called well trained professor 🙌🙌
My exam is in 1 week... I wish I found this waaaaayyyyy earlier. Super glad to have found it at all! Thanks for posting these videos!!!
I'm glad you finally found it, best of luck preparing for your exam!
Love your way of let us perceive your teaching
Glad to hear that!
neuroscience test today, thank you so much for you work!
You're welcome, good luck on your test!
This totally helped with my biopsyc module . THANK YOU, GOOD SIR
You're welcome!
Thanks! This was pretty conscise! Covered my 20 pages in a few minutes.
one hundred percent helpful! you're doing an amazing job out there helpin poor lil students)
Glad to hear that, thanks for commenting!
Thankyou yet again for helping me with my psych degree! You're awesome
Thanks, glad I can help!
Neuroscience is very important part of psychology....Thank you sir
thank you so much, it really helps me to understand this course.
You're welcome!
l can not explain in words how amazing you are 😭😭😭😭
thank u so much
You're very welcome, glad I can help! 😁

Incredibly helpful! Thanks so much
Glad to hear that!
This explanation was amazing!! THANK YOU!
You're welcome!
Thank you! This video helps people like me who’s starting to learn about psychology 🙏 more powers
Glad to hear that! Best of luck in your studies and let me know if you have any questions!
Been not paying attention in class and just started studying the day before the unit test 😭
THANK YOU! I appreciate your work so much :)

How do psychologists study sensation
Thank you. This was quite helpful.

hi sir I have question, what will happen when the perception is late/delayed?
This might cause a feeling of confusion, like when you hear a sound but can't identify what it is, or if you look at an image or painting and can't quite figure out what you're looking at right away. The sensation is there but how to properly perceive or interpret it may take a bit longer.
@@PsychExamReview thank you sir, I understand now!🤍
Thank you so much , it was helpful
You're welcome!
Thanks you once

Textbooks make this subject really boring. This module and "language" topic. Thank God for videos like these.
