In this video I cover the first box in the 3-box model, sensory memory, in greater detail. I explain how this store refers to information from all of the senses, though individual senses can be specified using terms like iconic memory or echoic memory. I also describe how the brief duration of sensory memory relates to managing the constant flow of information from the senses. This also relates to the myth that the mind has some sort of detailed record of all of our experiences. Next I explain George Sperling's work demonstrating the duration of sensory memory and how this relates to the role of selective attention in organizing our perceptions and moving information to the next box in our memory model, which is short-term memory.

I’ll admit, i laughed out loud when when you said “i hope you forget about that,” in reference to the myth about all information being stored somewhere in your mind. Very funny lol
You are a lifesaver. I have a psychology exam tomorrow. Thank you so much.
Also on a side note : you are very handsome
You're welcome. And you are very kind :) Good luck on your exam!

Excellent video.
I'm researching an as yet anomalous phenomenon that, as far as I know only affects me. I'm hoping that an inductor of your calibre might be able to shed some proverbial light on the matter.
The phenomenon occurs whenever I am working, studying or watching TV, i.e completely _zoned in_ to something. If there is a persistent noise (constant, intermittent or pulsating), whenever that noise *stops* I get the strangest feeling that I was focusing on it just before it stopped.
Maybe I'm just wiered.
I would guess that this is probably a situation where sensory adaptation has occurred (you stop noticing a constant stimulus) but then when it changes or stops you become aware of it again. Sensory adaptation occurs all the time (you adjust to the feel of the clothes touching your skin, ambient noises, temperature, etc.) so you may not always notice the changes but when you occasionally do notice the change it stands out.
@@PsychExamReview Thank you, I really appreciate your taking the time to reply!
Very helpful indeed.
Thank you sir for these lectures 🤍
You're welcome!
Hello Just like to thank you with your videos. I have this class online and have to read 3 long chapters and sometimes I can't grasp the information so this helps me a lot.

Sir what I learnt in the sensory memory is that; if we see a person all of a sudden and that person or let's say anything will get vanished after a while or maybe less than a second because of this memory but sometimes this gets opposite the person stays in mind for a longer period soo my question is that sir is it still the work of iconic memory or not ?(since this is still about vision)
If only so much info can be transferred from sm to wm how is it that we form memories that are extremely long like a birthday party, going to a amusement park ect, basically any large event.
There's a limit to how much we can attend to at once, though over the course of a long event we can attend to, and potentially remember, many details because we can shift our attention to different things at different times. Even in these cases, however, there's still a massive amount of information that would not be remembered; exact conversations, details of the environment, what everyone was wearing, etc.
Great. Than k you! Would you do a video about theory of reinforcment Clark Hull and Premack
Hi, you can find videos on reinforcement and the Premack Principle in my Learning Theory playlist here: ua-cam.com/play/PLkKvotUGCyLdWmS-YBp58DTmjN3Q9nih0.html I also have a video on Clark Hull's Drive Reduction Theory here: ua-cam.com/video/IwGfSaWZ5u0/v-deo.html
@@PsychExamReview thank you very much , I am very lucky to find your channel.
Amazing lessons 🙏🏾🙏🏾
Thanks!
Great job as always thanks
You're welcome!
hi, I have this understanding on how sensation, perception and memory are all interconnected. Please let me know if my understanding is correct.
First external events happen, then we have sensations entering our sensory system, we pay attention to some and perceive them and this leads to their sensory register or encoding into the sensory memory, then we pay more attention and encode it to STM, then more attention and we encode it to the long term memory.
I am bit confused, which stage of this entire process do we perceive the information because if we will not perceive sensation, how will we encode and store it in our memory?
This is a great question and I might not have the expertise to fully address the finer details. I'd say your overall understanding is mostly correct but that you might think of perception happening somewhere in between the raw sensory information coming into our sensory memory and the process of attention that might move it to short-term memory.
The reason I say "somewhere" in between is that it raises the question of whether sensory information can be perceived and influence behavior without attention being involved (perhaps it can, though there's a lot of debate about what and how in the case of subliminal information and priming research). There's also the possibility that you could sense something, not perceive it accurately, but still recall it well enough to "figure out" what it actually was and change your perception - such as hearing a strange sound, then correctly perceiving what it was a few moments later.
Hope this helps!
@@PsychExamReview Thank you so much!
Thank you
You're welcome!
These videos are really helpful. What would you suggest to someone who is dyslexic to help them digest information better when studying?
I'm glad they're helpful! It might be useful to try writing brief notes or one-sentence summaries as you go through each section, especially for dense reading. This is more work at first and will be slower but it will allow you to review the main ideas and look for connections more easily after you've gotten through the reading. If reading is really challenging then you might also look to supplement your studying with podcasts or audio lectures that reinforce the main ideas. Hope this helps!
@@PsychExamReview Sounds great. In fact I have just recently been using memory palace techniques, they really help to kind of help me move the new information when I encode with images since dyslexics have a weak short-term/working memory. I only recently found out about this so I still have a lot to learn.
To transfer information from sensory memory to short term memory, you need to pay attention to the stimulus (outside world, events or objects) or to the representation of the stimulus in your sensory memory? Maybe this question is kind of wierd. I´m having a hard time undertanding that moment from the 3-box model. Anyway, thanks for the video.
It may be possible that some things in sensory memory persist even without attention but this is difficult to assess. It could be argued that the effects of priming demonstrate a longer-term influence of stimuli that weren't directly attended to, but the effects of priming aren't clear and there have been many failed replications. Generally speaking, in the case of conscious memories, I'd say some form of attention is usually going to be necessary for information to remain in memory for more than a few moments.
when u say "it's like your reading the letters off your mind/sensory memory" do you mean after u hear the tone and are asked to recall or immediately trying to read the row when it's first appears?
I'm referring to after the tone to recall; the letters aren't visible on the screen anymore, but people can still "read" the letters in a particular row because all the letters are still in their sensory memory (though this fades very rapidly). They don't know which row will be asked for until the tone, but all the letters are available for about a second or so. If the tone is delayed by a few seconds, the sensory memory has already faded and people will make many more mistakes when trying to recall a specific row.
hi can you please tell me a situation in which sensory memory is useful for you? 😭😭
❤❤❤❤
Just because we can't recall visual information doesn't mean the information has been lost, isn't it? I'd think that it makes sense to say IF there is no information in our brain, then we can't recall it but the other way around, am not so sure
You're correct that we may still have some information or traces of a memory which can't be readily retrieved. This brings us to the role of implicit or non-declarative types of memory and possible influences below conscious awareness such as priming. This is an area where there are controversies and the strength of these influences and their biological mechanisms are not yet understood. I also discuss these topics briefly in other videos in the playlist here: ua-cam.com/play/PLkKvotUGCyLf3Y04uZuR52-1NceR5_JxZ.html
Thanks for commenting!
Wouldn't sperlings experiment be an example of short term or visual short term then? In the second you flashed those letters my eyes could read them before they disappear and I can remember the letters in that row after they dissapear.I do not see how delaying the tone for one second or more could make the participants forget and make mistakes? Or maybe the one in this video is longer than a quarter of a second?
The letters that are correctly recalled would be in short-term, but the fact that subjects could recall any row asked for (asked after the letters were gone from the screen) means that all the letters were (very briefly) in visual sensory (or iconic) memory.
So for about a second or two all letters are in sensory memory, then attention towards a certain row allows those to be moved to short-term while the other rows quickly fade away.
The demo in this video is just an approximation of the procedure to help explain it, the timing and presentation are not identical to Sperling's actual study.
Hope this is clearer!
Thank you!
@@realitywarperbenj5456 No problem!
Thanks💛!!
You're welcome!
So will it be correct to say that the dream that we don't remember is an example of sensory memory as it lasts within some period of time? By the way, ur video was helpful 👍😊
Though dreams can incorporate some external sensory experiences (like the sound of an alarm clock) they generally wouldn't be examples of sensory memory and could probably be classified as either short-term or long-term, depending on how long the memory lasts.
very helpful
Glad to hear that!
Sir can you give me some examples of sensory memory please I need it for making my assignment??
Any information from your senses that is briefly available in your mind can be an example of sensory memory. So the exact details of a landscape or painting, the exact sound of something crashing to the floor, etc. are all examples of sensory memory. Hope this helps!
@@PsychExamReview thank you so much I needed it your channel is so helpful ♥️♥️♥️
@@nutsdairy3270 You're welcome, glad to hear it's helpful!
@@PsychExamReview pleasure is mine ♥️♥️
Amazing
I srsly would like to marry your brain right now.
The experiment to prove the existence and the
Your opinion is correct and auditory sensory memory (echoic memory) does last a bit longer than visual sensory memory (iconic memory) but it is still estimated to be only about 3-4 seconds. I'm not familiar with research on duration for other senses like touch, taste, or scent, but if anyone has some info I'd be interested in taking a look!
Does not last a second. Its last less than 500 MS
Who's here coz of Dr. Nicdao? lol
Can you please stop using blue colored pen in ur presentation, it gets camouflaged over black, otherwise ur content is superb!!
Sure, I'll make sure to avoid it in future videos!
Assuming that someone was deaf, or blind. Would this enhance their iconic/echoic memory? Say, instead of keeping iconic memories for around 1 second, would this last longer due to their disability?
I am indebted to you.......
Impossible; use and share your knowledge and consider any debt paid :)
I see a human, there:)
Say an object I'm looking at and never seen before disappears after 1 second of observation/memorization
if I try to remember what the object looks like after it disappears would this be short term or sensory?
Your initial memory of the object would be sensory memory. Paying attention to it after and trying to recall details would then move some (but not all) of that sensory memory information into your short-term/working memory. Hope this is clear!
I see? So at what point would it become fully short term memory?
@@jamaicanloneanimal8224 As soon as some of the details have faded (within a few seconds), whatever remains could be considered to be short-term/working memory.
