Which memory is about what people know and can report?
Explicit memory refers to knowledge or experiences that can be consciously remembered. As you can see in Figure 9.2, “Types of Memory,” there are two types of explicit memory: episodic and semantic.
How long after learning the lists does most forgetting happen?
He found that most forgetting occurs during the first nine hours after learning . Practice, both massed and distributed over time, also affects relearning forgotten material. Ebbinghaus also found that the more an individual rehearses a list of syllables, the better the syllables are recalled.
How can a person get information to travel from sensory memory to short-term memory?
Information is passed from the sensory memory into short-term memory via the process of attention (the cognitive process of selectively concentrating on one aspect of the environment while ignoring other things), which effectively filters the stimuli to only those which are of interest at any given time.
What amount of time does it typically take before such information is lost from short-term memory?
Most of the information kept in short-term memory will be stored for approximately 20 to 30 seconds , but it can be just seconds if rehearsal or active maintenance of the information is prevented.
When creating a presentation many public speaking instructors will tell you to develop a strong opening?
When creating a presentation , many public speaking instructors will tell you to develop a strong opening or attention getter to your presentation as well as a good summary and finish.
What is the hippocampus?
Hippocampus is a complex brain structure embedded deep into temporal lobe . It has a major role in learning and memory. It is a plastic and vulnerable structure that gets damaged by a variety of stimuli. Studies have shown that it also gets affected in a variety of neurological and psychiatric disorders.

What are the 3 theories of forgetting?
There are at least three general categories of theories of memory which suggest reasons why we forget. The theories can be classified as psychological, neurochemical, and physiological .
How does information from stimuli become a memory?
Memories occur when specific groups of neurons are reactivated . In the brain, any stimulus results in a particular pattern of neuronal activity—certain neurons become active in more or less a particular sequence. ... Memories are stored by changing the connections between neurons.
How does the multistore model explain the information processing of individuals?
What is the Multi-Store Model? The multi-store model is an explanation of memory proposed by Atkinson and Shiffrin which assumes there are three unitary (separate) memory stores, and that information is transferred between these stores in a linear sequence.
How is sensory information processed by the brain as memories?
Sensory memory is the perception of sight, hearing, smell, taste, and touch information entering through the sensory cortices of the brain and relaying through the thalamus . It lasts only milliseconds and is mostly outside conscious awareness.
Which only lasts for about 15 to 30 seconds?
Short-term memory takes information from sensory memory and sometimes connects that memory to something already in long-term memory. Short-term memory storage lasts 15 to 30 seconds.

How does the hippocampus affect learning?
Study shows how the hippocampus provides information to other brain areas during learning. Summary: Without an intact hippocampus, forming new memories is impossible. Researchers have found an equally important role for the hippocampus: feeding information to brain areas responsible for learning .
How long is auditory memory?
Echoic memory: Also known as auditory sensory memory, echoic memeory involves a very brief memory of sound a bit like an echo. This type of sensory memory can last for up to three to four seconds .
Can a person have a photographic memory?
Photographic memory is a term often used to describe a person who seems able to recall visual information in great detail. ... However, photographic memory does not exist in this sense .
How long does echoic memory last?
When your ears hear a sound, they transmit it to the brain where echoic memory stores it for about 4 minutes . In that short time, the mind makes and stores a record of that sound so that you can recall it after the actual sound has stopped. This process is ongoing, whether you are aware of the sounds or not.

Also known as the sensory register, sensory memory is the storage of information that we receive from our senses. Examples of Sensory memory include seeing a dog, feeling gum under a chair , or smelling chicken noodle soup. Our eyes, nose, and nerves send that information to the brain.
How sensory memory is useful?
The knowledge of how sensory memory affects us is important in the study of memory and aging. Because sensory memory is a first input that helps to build a person’s short- and long-term memories , knowing that it slows down with aging can help to understand why and where memory starts to decline.
How does the hippocampus affect memory?

The hippocampus is also where short-term memories are turned into long-term memories. These are then stored elsewhere in the brain.
How does the brain remember information?

Brain cells work together to make the brain as efficient as possible.
How does the hippocampus store memories?
According to McGills , the hippocampus takes simultaneous memories from different sensory regions of the brain and connects them into a single “episode” of memory , for example, you may haveone memory of a dinner party rather than multiple separate memories of how the party looked, sounded , and smelled.
How does Atkinson and Shiffrin’s model of memory work?
Atkinson and Shiffrin believed that once information enters the brain, it must be either stored or maintained and that the information which is stored goes into three distinct memory systems: the sensory register, short-term memory, and long-term memory.
How does KF support working memory model?
KF’s impairment was mainly for verbal information – his memory for visual information was largely unaffected. This shows that there are separate STM components for visual information (VSS) and verbal information (phonological loop). Working memory is supported by dual-task studies (Baddeley and Hitch, 1976).
