Working memory: Studies have found that children with dyscalculia showed impaired performance on working memory tasks compared to neurotypical children. [ 48 ] [ 49 ] Furthermore, research has shown that children with dyscalculia have weaker activation of the intraparietal sulcus during visuospatial working memory tasks. [ 6 ]
Absentmindedness is a gap in attention which causes memory failure. In this situation the information does not disappear from memory, it can later be recalled. But the lack of attention at a specific moment prevents the information from being recalled at that specific moment. A common cause of absentmindedness is a lack of attention.
The difference in memory between normal aging and a memory disorder is the amount of beta-amyloid deposits, hippocampal neurofibrillary tangles, or amyloid plaques in the cortex. If there is an increased amount, memory connections become blocked, memory functions decrease much more than what is normal for that age and a memory disorder is ...
True photographic memory (the ability to remember endless images, particularly pages or numbers, with such a high degree of precision that the image mimics a photo) has never been demonstrated to exist in any individual, [463] although a small number of young children have eidetic memory, where they can recall an object with high precision for ...
Before the 1960s, there was very little research that studied the workings of short-term memory and rapid memory loss. Lloyd and Margaret Peterson observed that when people are given a short list of words or letters and then are distracted and occupied with another task for few seconds, their memory for the list is greatly decreased.

Causes vary between the different types of disorders but most include damage to the memory portions of the brain. [ 6 ] [ 7 ] [ 8 ] Treatments depend on how the disorder is caused. Medication and therapies are the most common treatments; however, for some types of disorders such as certain types of amnesia , treatments can suppress the symptoms ...
Lacunar amnesia is the loss of memory about a specific event. This specific form of amnesia is caused by brain damage in the limbic system which is responsible for our memories and emotions. When the damage occurs it leaves a lacuna, or a gap, in the record of memory within the cortex region of the brain. There is a general belief that certain ...
While the efficiency of encoding and storage processes allows older children to remember more, [29] younger children also have great memory capacity. Infants can remember the actions of sequences, the objects used to produce them, and the order in which the actions unfold, suggesting that they possess the precursors necessary for ...
