Are human beings fundamentally logical creatures? Well, yes and no! It turns out that we are often quite bad at logical thinking, but we become very logical under certain circumstances. What governs when we are better and worse at logical thinking? The surprising answer has a lot to do with our social nature, and our evolutionary history! 0:00 - Intro 1:05 - What is logic? 5:42 - If… then… 10:1...
Reasoning with Heuristics

How rational are human beings? What kinds of mental shortcuts do we take, and how can reasoning go wrong? In this lecture, I'll talk about decision-making heuristics, rationality, and some possible explanations for our less-than-rational tendencies! 0:00 - Intro 0:48 - Thinking fast and slow 3:39 - Snap judgments 8:49 - Representativeness heuristic 17:09 - Availability heuristic 22:14 - Anchori...
Visualizing the brain - brain waves
Просмотров 1,9 тыс.2 года назад
Neuroimaging techniques can tell us a lot about how the brain works. Tracking blood flow (with fMRI) can tell us where processes are happening in the brain, but it can’t tell us what or when. That’s where EEG comes in! By measuring the electrical activity of neurons more directly, we can learn a lot about what the brain is actually doing-what kinds of algorithms the brain is executing and how t...
Visualizing the brain - functional neuroimaging

We live in a high-tech future, where looking inside the black box of the brain is possible-with help from functional neuroimaging! In this video, we'll talk about some modern techniques used to probe cognition by measuring brain activity, and what these results can (and can't!) tell us about the mind. 0:00 - Intro 2:00 - Two types of neuroimaging 6:19 - PET (positron emission tomography) 8:17 -...
What can we learn by studying the brain?
Просмотров 1,3 тыс.2 года назад
The human mind doesn’t exist in a vacuum-it’s causally linked to our physical brains. In this video, we’ll talk about how cognitive processes are implemented in the brain, and what the organization of the brain can tell us about topics like perception, language, and even consciousness! 0:00 - Intro 2:01 - Why study brains? 4:59 - “Geography” of the brain 8:25 - Contralateral organization 15:33 ...
How do we remember? An overview of Long Term Memory
Просмотров 1,9 тыс.2 года назад
Memory is an active system that receives, stores, organizes, alters, and retrieves information. Our long-term memory is the subset of memory dedicated to long-term storage and retrieval. Memories about childhood, facts and trivia, and basic skills like how to ride a bike are all filed away in long term storage. In this video, we’ll see how our long-term memories are stored and retrieved-althoug...
Search algorithms in the mind? What memory-scanning can tell us about mental algorithms!
Просмотров 1,3 тыс.2 года назад
Working memory is the “workbench of the mind”-the place where our mind performs processes and manipulates information. In this video we’ll zoom in on a particular process-memory search-to see how the mind executes an algorithm to find a piece of information in working memory (and how we know this is true!). 0:00 - Intro 2:21 - Search algorithms 6:30 - Search time 11:53 - Sternberg’s experiment ...
Short Term Memory

Memory is an umbrella term for a lot of systems with different properties and different functions. In this video, we’ll talk about the short-lived memory systems-sensory memory, a buffer for information from our senses; and working memory, the workbench where we manipulate information to perform cognitive functions. 0:00 - Intro 3:25 - Stages of memory 6:15 - Sensory memory 15:36 - Working memo...
Mental Imagery

Light enters our eyes and is converted to a code that our minds can understand, but what happens then? How do our minds generate and manipulate mental imagery to recognize objects and perform other important cognitive tasks? In this video, we’ll go over some models of visual object recognition and talk about some specific ways the mind can manipulate mental images (and how we know!). 0:00 - Int...
Visual Perception

We navigate the world using our senses-and our most important sense is probably our sense of sight. Our eyes take in light from the outside world and translate it into a code that our minds can manipulate, but this is a very complex process. In this video, we’ll see how our mind takes in and interprets visual information to give us an understanding of the world around us. 0:00 - Intro 2:14 - Se...
The Meaning of Meaning

How does this guy only have 5k subscribers? I thought it was 5million at first glance... Keep up the good work
what are some potential career paths for this? im interested in business, technology, as well as design.
What a 14 year old búm making long non sénsical videos on yt
Philosophy and psychology we have Carl Jung psychoanalysis. Carl Jung proves Neuroscience he was right. We need some laws over psychology , perhaps people we don’t problems with the misuse of philosophy, and people start respecting philosophy and all real Genius who really provide positive impact in our society and the history of humanity.
Your Videos are Excellent
Quite informative. At least I know my enemy for what it is: DEHUMANIZATION. Fortunately, you have lots of time to figure out what garbage these physicalist theories are, and what a threat they are to our very humanity. Cheers.
When you say "Qualia", it also makes me think you are just describing phenomenology which is "subjectivity for objectivity". Now I'm not sure about AI or computers having consciousness, but phenomenology is a very real thing. I was also curious if you ever looked into the left-brain right-brain dichotomy or had any videos on that? This video reminds me of that as well. Very well made video for the pseudointellectual that I am!
Brilliant 👏 ❤thanks a million
I think you have to learn more about behaviorism; there is not such an extreme divorce between cognitivism and conductism. Just take a look at the most recent studies done by Albert Bandura and the application of behavioural theory in AI to educate and control the world.
Isn't it actually a logical fallacy to argue that : if we do operation A, it takes a certain amount of time. It took this certain amount of time, therefore operation A was done and not some other operation. This does count as abductive reasoning, but isn't actually a valid inference. We can only conclude that: given it didn't take this certain amount of time, operation A wasn't done. And in this particular case it just tells us that the mathematical transformation wasn't done, however we don't know whether mental rotation via 3d imagery is the only other way of figuring out rotations problems, and so we can't conclude that it is indeed the right model only by ruling out another
But what does computation as operation over representations even mean? How does it tie in with the more formal notion of computation?
Excellent. I was able to remember the 7932 because I used it as a connection to the date of my birth: 7 and 3 (50% accomplished) and then the difference between 9 and 2 = 7 related to my birthday again, so associated with my old long time memory. Interesting to say, I watched 20 minutes of the video, stopped it and played the rest of it the next day. Therefore I was able to remember my strategy 24 hours later. I just had to think of my birthday. Cheers
great video. love this topic. glad i found your channel!
Hey is Active recall or spaced repetition which is better for memories theory book like biology.
It’s pretty amazing your video on cog sci has instead helped me understand discrete maths.
15:40 I think you nailed the AI one right here. Just not sure how you can program empirical data into a “mind” and then it develops subjective experience. I feel humans have become enlightened enough to access this “thing in itself” dimension/substrate which we can’t prove exists, but gives rise to complex abstracts like consciousness.
So clear! Thank you so much for the video!
Loving these videos About to start my cogsci degree in october and these are so interesting
The fact that your reading and pausing massively is putting me off and makes me think you have little subject knowledge. So whilst researching such a subject it make me want to find another channel to watch. This isn't me trolling but me giving constructive critique from one content creator to another.
This is kind of my like argument against purely empirical research method that dismisses that subjectivity needs to be analyzed. How an evolutionary psychologist might try to analyze the human mind largely influenced by its physical components versus a cultural anthropologist who immerses themselves in the subjectivity. This is not an argument against analyzing at the physical level just that the perspective of analyzing subjectivity is not as important and devalued because it doesn't always fully use the scientific method in its qualitative approach yet it is how we can map out our software will others can also map out the hardware. Also if you believe in monism then you will realize subjectivity is the software that rises out of the physical mechanism of the mind.
thankksss for meaking this videos
You started poorly but otherwise a good presentation. Light does not enter the eyes and go to the brain. It is important to reinforce that nothing but blood, neurons, cerebral spinal fluid enter and exit the brain.
The mind is information processing for producing behavior. Other parts of the brain (such as the endocrine system) also produce behavior (of a different type). DNA and other information processing in the body do not produce behavior. They produce metabolic activity.
Termite and other species are not collectively a mind. Collectively they do the work of two birds building a nest, but the birds also act on instinctive instructions so the two birds do not make a mind. It is possible that only humans have a mind---both individually and working collectively.
I have discovered what the mind does and how. It is that part of the computational brain that is not a computer. This does not contradict your lecture. One can place names on various processes as one wishes. For me, my work, the brain contains a computer that allows us to determine things like how much change to give a customer who purchases $7.50 in goods. The mind, again by definition, is the part of the brain doing something else--which I explain. All the best.
20:10 You might show the wrong example mate, the law of small numbers .... it's not about how many people die on a car acc, but how many trips on cars that the car crashes and someone dies how many plane trips happen, and how many of them crashed and someone dies, don't play with numbers or percentage to prove the concept mate the example might be totally wrong
18:26 no the hard problem of consciousness will come in our way . zombie argument which tells that what if humans made same clone of you , which does everything the way you do . So turing machine won't be able to conceive what reality is... From perspective of consciousness, A turing machine won't even be able to know that it even exist ... There is no difference between it and a rock .
22:26 obviously it's true that experience exists ontologically subjective but I don't understand the differentiating line between physicalism and dualism . There are scientist who don't deny it but say because of brain processes the subjective experiences emerges. They just have different mode of existence
4:58 wow it's amazingly put in words ... He must have been a legend it's shows his level of smartness
The whole thing on Weber's law with the bag of pennies (and some falling) was wayyy too long and not really helpful....but you made it up by ending with this very important phrase: "The mind is an information processor that performs computations over representations"!
Very nice talk. I'm a physician interested in Matter to Mind mystery for many years; have read lots of books, watched lots of videos but I think Ryan Rhodes talks/teachings are very good and he explains things in a very intellectual and unique way. But if you don't mind, can you tell me a bit about yourself Ryan; who are you :), what is your background and education in?
Thanks! I'm a neurolinguist, and I teach cognitive science at Rutgers University.
@@RYANRHODES-cogsci your lectures are awesome! And just the perfect lengths of 20-30 minutes :) My question was more pertaining to your educational background - where did you go to school? PhD in neuroscience?
Thanks again! I have a BA, MA, and PhD in linguistics. I got my PhD at the University of Delaware, where I managed an EEG lab. I don't have a background in neuroscience, so I've had to learn a lot on the way! @@THash-qs5qg
@@RYANRHODES-cogsci That's amazing what you've done without a background in neuroscience. I, too, don't have a background in neuroscience (I'm a humble Pediatrician) but I've been so fascinated with the mind-body problem, that I've probably read/watched as much as a neuroscience student :) Keep up the great work Ryan!
@@THash-qs5qg Thanks! Being a doctor is incredible too--a ton of work and study! I was never cut out for it
Thank you for the explanation. This is much more entertaining than reading Bermúdez's book :D
Glad to hear it!
You are saving my mind and my CogSci grade!!! Thank you!!
I'm glad it helped!
Hegel and Lacan!
This was amazing, thank you!
This was amazing! Appreciate your efforts highly.

You are fantastic!
Everything went fine until almost the end, when you say "the most intelligent species on the planet". This is NOT a valid statement since no other species can argue that. In fact, perhaps dolphins can see us as a joke ... we don't know that ...
No other species can argue because they arent as intelligent. Intelligence is complexity of communiacation. I dont jsut mean langauge, we communicate in so many ways that dolphins, because of their enviroment cant. One example, we communicate with clothing. For dolphins that is literally impossible because, well theyre underwater. They may have similiarly advanced brains, but they will never be able to reach our intelligence because of where they are at. So it is very clear we are the most intelligent species on the planet because we collectivly have by far the most advanced/complex communication (in terms of scope, outlet and channels)
Thanks Ryan!!! But what I am wondering now is how sternberg's task can measure our working memory? Does it goes with measuring the accuracy of responses by manipulating the length of the stimuli?? can you answer it??
awesome video. thanks for creating and sharing this :)
In regards to Mary's room I think we can by now almost confidently say that she will have learned something. I'm saying this because there's been glasses called "enchroma glasses" for people who have been born with various forms of color blindness to make them capable of seeing colors more properly and there is a plethora of massive emotional reactions to colorblind people with huge emotional outbursts, tearing up and other things (check on youtube "colorblind people see color for the first time"). Now obviously unlike with Mary's room these people do not know everything there is to know about colors, but a bunch of them think they know really enough about colors and they don't even expect to "learn" anything new really or what the fuzz is about right until they have experienced the act of seeing the colors more nuanced. And most colorblind people actually are not monochromats, they do not see the world in black and white like in Mary's room, yet still the reaction to seeing the colors more properly is tremendous. Stern and hardened men breaking into tears from the very act of experiencing these colors for the first time. There is such a vast amount of people who have had such reactions to color that it seems to be a universally shared experience to be deeply touched and strongly emotionally moved simply by the initial act of moving from colorblindness to experiencing more color. A really interesting part about this is that the enchroma glasses do literally quite nothing to the chemistry of the brain, it's really just the switch to a more nuanced experience while wearing those glasses. It's not quite Mary's room but probably as close to it as we can get in the real world.
I saw blue and black very strongly. Then after you showed those two carton dresses side by side, I don't know what happened, now I see gold and white... does anybody know what happened here? 🙄🙄 I should be seeing only one color combination right?
WE MUST PROTECT THIS RYAN AT ALL COSTS! HE IS TOO VALUABLE TO US! Goodness me what a great video! I’m starting my training at Kings University in October to become a high-intensity cognitive behavioural psychotherapist. We have been sent some pre-reading, and this has been fantastic in supporting my reintroduction to the subject. I needed a summarised deep dive into the history of the cognitive movement, covering how it developed, intersected and intertwined with behaviourism. Thank you so much for taking the time and effort to put this together! You’ve definitely got a like and subscribe for me please keep this video is coming!
Great video! Really made me understand this topic better!🎉
didnt understand this concept even remotly before watching youre video, please dont stop making videos, youre an amazing teacher
"Process of computing a referent" is great, but it sounds a bit too abstract. The act of articulating the word "water" in distinct circumstances on various planets can be approached as purely performative endeavor. Consider the scenario where an individual points to a watercooler and requests a cup of water. In numerous real and hypothetical situations, this simple act could prompt someone else to fulfill the request by engaging with the machine. This process exhibits a self-referential quality, where the notion at hand cannot be neatly categorized as either externalist or internalist. It necessitates the involvement of an individual in making a statement, at the same time the statement itself may lack any corresponding internal contents. All that matters, its articulation consistently makes the job done. Thanks for a very engaging content!
Sold in less than 30 seconds. Subscribed liked and commenting in hopes the algorithm catches my drift. Thanks for the work.
