Resumo

TLDRThis video tutorial covers the information processing theory, focusing on how our brains receive, process, and store sensory information. It explains the roles of the sensory memory, short-term memory, and long-term memory, highlighting the processes of encoding and retrieval. The tutorial emphasizes selective attention in managing overwhelming sensory input and discusses the limitations of multitasking with visual and auditory tasks. Finally, it describes how responses to stimuli are determined and how effective responses are stored in long-term memory.

Conclusões

  • 🧠 Information processing theory explains how we process stimuli through our senses.
  • 👀 Sensory memory captures images (iconic) and sounds (echoic).
  • ⏳ Short-term memory holds information temporarily with limited capacity.
  • 💾 Long-term memory permanently stores vast amounts of information.
  • 📝 Encoding connects new memories with existing ones.
  • 🔄 Retrieval brings memories from long-term back to short-term for use.
  • 🚦 Selective attention filters out irrelevant stimuli, aiding focus.
  • 🔍 Multitasking is possible with visual and auditory tasks, but not dual visual or auditory tasks.
  • 🛑 A search and response mechanism determines how we react to stimuli.
  • 📥 Effective responses are stored in long-term memory for future reference.

    This video introduces the information processing theory, explaining how our brains constantly process vast amounts of stimuli through our senses: sight, sound, smell, and touch. It describes the function of echoic and iconic memory, emphasizing that attention is essential for transferring information from sensory memory to short-term memory. Moreover, short-term memory is highlighted as having limited capacity, while long-term memory is vast and permanent. The crucial processes of 'encoding' (connecting new memories with existing ones) and 'retrieval' (accessing information from long-term memory) are introduced, along with the concept of selective attention to filter out distractions when overwhelmed. The video also discusses multitasking limitations, stating that auditory and visual tasks can be performed simultaneously but not when both are in the same category. Finally, it explains how the search and response process organizes actions based on received stimuli and how effective responses are recorded in long-term memory for future reference.

Vídeo de perguntas e respostas

  • What is information processing theory?

    It is a theory that describes how our brains process, store, and retrieve information through different types of memory.

  • What are the types of memory involved in information processing?

    The types of memory include sensory memory, short-term memory, and long-term memory.

  • What is encoding?

    Encoding is the process of creating connections between new memories and existing memories for storage in long-term memory.

  • What is selective attention?

    Selective attention is a process that filters out unimportant stimuli, allowing focus on relevant information.

  • Can we multitask with visual and auditory tasks?

    Yes, we can multitask with visual and auditory tasks, but not with two visual or two auditory tasks simultaneously.

  • What happens when one receives a stimulus?

    A search occurs to determine an appropriate response to the stimulus.

    welcome to this tutorial on the
  • 00:00:01
    information processing theory
  • 00:00:03
    every second of every day we are exposed
  • 00:00:06
    to thousands of stimuli
  • 00:00:08
    our brain takes information through
  • 00:00:10
    sight sound
  • 00:00:11
    smell and touch these are known as the
  • 00:00:14
    senses
  • 00:00:15
    sounds are picked up by the echoic
  • 00:00:16
    memory and images are picked up by the
  • 00:00:18
    iconic memory
  • 00:00:20
    this information is then transferred to
  • 00:00:22
    the sensory memory
  • 00:00:24
    only when we pay particular attention to
  • 00:00:26
    a particular sense
  • 00:00:27
    is it then transferred from our sensory
  • 00:00:29
    memory to our short-term memory
  • 00:00:31
    our short-term memory contains
  • 00:00:33
    information about what we see
  • 00:00:34
    and hear in this present moment in time
  • 00:00:37
    the short-term memory has a very limited
  • 00:00:39
    storage capacity and cannot permanently
  • 00:00:42
    hold this information
  • 00:00:43
    your long-term memory on the other hand
  • 00:00:45
    is exactly the opposite
  • 00:00:47
    it is large and permanently stores
  • 00:00:49
    information
  • 00:00:50
    the process of getting information from
  • 00:00:52
    your short to your long-term memory is
  • 00:00:54
    called encoding
  • 00:00:55
    encoding is when you create a connection
  • 00:00:57
    between the memories you already have
  • 00:00:58
    and the new memories received the
  • 00:01:00
    processing of getting memories out of
  • 00:01:02
    your long-term memory
  • 00:01:03
    and back into your short-term memory for
  • 00:01:05
    use is called retrieval
  • 00:01:07
    when our short-term memory experiences a
  • 00:01:09
    large number of senses
  • 00:01:10
    it can become overwhelmed when this
  • 00:01:12
    happens we use a process called
  • 00:01:14
    selective attention
  • 00:01:15
    this filters out the messages that are
  • 00:01:17
    not important to us allowing us to focus
  • 00:01:19
    on those that are
  • 00:01:21
    when considering the concept of
  • 00:01:22
    multitasking we realize that it is
  • 00:01:24
    possible to do visual
  • 00:01:25
    and auditory tasks at the same time for
  • 00:01:28
    example
  • 00:01:29
    talking and walking however we cannot do
  • 00:01:32
    two visual or auditory tasks at the same
  • 00:01:34
    time
  • 00:01:34
    for example reading two books or
  • 00:01:36
    watching two tv shows
  • 00:01:38
    yes if we do this some information may
  • 00:01:41
    get through
  • 00:01:42
    but it will be limited finally when our
  • 00:01:44
    senses receive a message
  • 00:01:46
    a search happens to determine what the
  • 00:01:47
    response to the message will be
  • 00:01:49
    for example when you bang your head the
  • 00:01:51
    surgeon response may be to sit down or
  • 00:01:53
    call for help
  • 00:01:55
    search and response organizes your
  • 00:01:56
    actions telling your body exactly what
  • 00:01:58
    to do
  • 00:02:00
    feedback is then received through
  • 00:02:01
    observation to check if the response was
  • 00:02:03
    effective
  • 00:02:04
    if you view a response as being
  • 00:02:06
    effective it will then be stored in your
  • 00:02:08
    long-term memory for future use
