Memory is essential for learning new information, as it functions as a site for storage and retrieval of learned knowledge. Two categories of long-term memory are used when engaging in learning. The first kind is procedural: how-to processes, and the second is declarative: specific information that can be recalled and reported. [9]
Focal retrograde amnesia (FRA), sometimes known as functional amnesia, refers to the presence of retrograde amnesia while knowledge acquisition remains intact (no anterograde amnesia). Memory for how to use objects and perform skills ( implicit memory ) may remain intact while specific knowledge of personal events or previously learned facts ...
Learning is shown when the rat swims a more direct route to the obscured platform. Small rodents can also be easily conditioned using taste aversion or odor aversion techniques. Performing neurotoxic lesions in these conditioned rodents is an excellent way to study the neural basis of aversion learning and memory. [46]
Source amnesia is not a rare phenomenon – everybody experiences it on a near daily basis as, for much of our knowledge, it is important to remember the knowledge itself, rather than its source. [4] However, there are extreme examples of source amnesia caused by a variety of factors. Phineas Gage exemplifies an individual who had frontal lobe ...
For example, some patients show improvement on the pseudorandom sequences experiment just as healthy people; therefore, procedural learning can proceed independently of the brain system required for declarative memory. Some patients with amnesia are able to remember skills that they had learned without being able to consciously recall where ...
Childhood amnesia, also called infantile amnesia, is the inability of most adults to retrieve episodic memories (memories of situations or events) before the age of three to four years. It may also refer to the scarcity or fragmentation of memories recollected from early childhood, particularly occurring between the ages of 3 and 6.
Research into childhood memory includes topics such as childhood memory formation and retrieval mechanisms in relation to those in adults, controversies surrounding infantile amnesia and the fact that adults have relatively poor memories of early childhood, the ways in which school environment and family environment influence memory, and the ...
The development of memory is a lifelong process that continues through adulthood. Development etymologically refers to a progressive unfolding. Memory development tends to focus on periods of infancy, toddlers, children, and adolescents, yet the developmental progression of memory in adults and older adults is also circumscribed under the umbrella of memory development.
