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

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.
@PsychExamReview
@PsychExamReview 3 года назад
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.

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)

These videos are really helpful. What would you suggest to someone who is dyslexic to help them digest information better when studying?
@PsychExamReview
@PsychExamReview 5 лет назад
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.

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?
@PsychExamReview
@PsychExamReview 4 года назад
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.
@madeocafea9921
@madeocafea9921 4 года назад
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.
@PsychExamReview
@PsychExamReview 4 года назад
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.

@Ag-bk1zw
@Ag-bk1zw 2 года назад
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?
@PsychExamReview
@PsychExamReview 2 года назад
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!

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.
@PsychExamReview
@PsychExamReview 4 года назад
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.

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 👍😊
@PsychExamReview
@PsychExamReview 4 года назад
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.
@realitywarperbenj5456
@realitywarperbenj5456 4 года назад
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?
@PsychExamReview
@PsychExamReview 4 года назад
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!

@PsychExamReview
@PsychExamReview 4 года назад
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!

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
@PsychExamReview
@PsychExamReview 4 года назад
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: ru-vid.com/group/PLkKvotUGCyLf3Y04uZuR52-1NceR5_JxZ Thanks for commenting!

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.
