three-stage model - ANSWER- We mentioned that the------of memory is based on an
information-processing metaphor. The model was developed by Richard Atkinson and Richard
Shiffrin (1968) and later modified. According to this model, memory works like this: Storage:
information is saved here for future use, like the stuff save of a computer; Retrieval: this
information can be accessed for reuse, like pulling up a file. Encoding function: this represents
input into the system such as typing and entering information by keyboard.
1.Sensory memory
2.Short-term memory
3.Long-term memory - ANSWER- One of the longest running theories about how our memory
works is the three-stage model. With this theory, the three systems of memory (or information
processing) are the encoding function, storage, and retrieval. The three stages are:
Memory - ANSWER- ------ is one of the most studied topics in psychological research. ----- is
important not only for learning, but for functioning in everyday life. Without ------, we couldn't
make friends, hold jobs, or perform everyday tasks.
short-term memory - ANSWER- An update on this theory says that ---- is more like working
memory, or a mental work-space that coordinates the processing and transmission of information.
Chunking and elaborative or maintenance rehearsal - ANSWER- ------ are two methods that
can increase the limited capacity of short-term memory.
Long-term memory - ANSWER- ----- is now thought to have three separate modules. These
are procedural memory, semantic memory, and episodic memory. Semantic and episodic memory
are both part of declarative memory.
Long-term memory - ANSWER- is now thought to have three separate modules. These are
procedural memory, semantic memory, and episodic memory.
long-term memory - ANSWER- The vast store of information in------ often makes retrieval
difficult. School exams are often essentially memory tests that come in two basic forms: recall or
recognition. Recall is more difficult than recognition, and is therefore a stricter test of memory.
---- - ANSWER- The level at which information is initially processed can make a difference in
how well it is remembered. Deeper processing, which involves thinking about the meaning of
information, helps to retain information better than shallow processing.
, associative networks - ANSWER- A newer model of how our memory is organized is known
as ----- These networks are thought to contain clusters of conceptually linked information, which
is often accessed by a process known as spreading activation.
Decay theory
Interference theory
Reconstruction (schema) theory
Motivated forgetting (or repression) - ANSWER- Psychologists also like to study why we
forget. There are four main theories of forgetting:
various parts of the cortex as well as the hippocampus, the amygdala, and the cerebellum. The
thalamus also has an as yet unknown role. - ANSWER- The biological basis of memory is
another focus of research. A number of brain regions play a part in encoding, consolidating, and
storing long-term memories. These include:--------
The three-stage model says - ANSWER- just like in a computer system, information in our
memory is encoded, stored and retrieved.
Sensory memory (or sensory register)
Short-term (or working) memory
Long-term memory - ANSWER- The three stages of memory under this model can be thought
of as subsystems, registers, or levels. These are not necessarily physical places, but simply terms
for the working parts of memory. The three stages are:
(for 15-25 seconds) - ANSWER- In the three-stage model of memory, the sensory register
receives incoming sensory input; short-term memory processes it and holds it briefly------ , and
long-term memory stores the information indefinitely.
Sensory Memory - ANSWER- can hold an exact reproduction of an incoming stimulus but only
for a brief period of time (less than a second). If the information is not immediately transferred to
short-term memory, it will be lost.
Sensory memory - ANSWER- actually contains subsystems for the different senses. For visual
images, there is iconic memory, for sounds there is echoic memory, and so on.
For visual images - ANSWER- there is iconic memory, for sounds there is echoic memory, and
so on.
------ - ANSWER- If sensory memory is so fleeting, how do scientists even know it exists?
How do they know how long an incoming stimulus can be stored there? Much light was shed on
this question through an ingenious memory experiment devised by psychologist George Sperling
in 1960.
