In recent decades, it has become one of the principal pillars of a branch of science called cognitive neuroscience, an interdisciplinary link between cognitive psychology and neuroscience. Processes

A. Sensory memory

* The ability to look at an item, and remember what it looked like with just a second of observation, or memorization, is an example of sensory memory. * The capacity of sensory memory was approximately 12 items, but that it degraded very quickly (within a few hundred milliseconds). * This type of memory cannot be delayed via rehearsal.

* Iconic memory is a type of sensory memory that briefly stores an image which has been perceived for a small duration. * Echoic memory is another type of sensory memory that briefly stores sounds which has been perceived for a small duration.

B. Short-term memory

* This memory allows recall for a period of several seconds to a minute without rehearsal. * Its capacity is also very limited.
* Memory capacity can be increased through a process called chunking. For example, in recalling a ten-digit telephone number. * Short-term memory is believed to rely mostly on an acoustic code for storing...
