Stress can cause acute and chronic changes in certain brain areas which can cause long-term damage. [4] Over-secretion of stress hormones most frequently impairs long-term delayed recall memory, but can enhance short-term, immediate recall memory. This enhancement is particularly relative in emotional memory.
Motivated forgetting is a theorized psychological behavior in which people may forget unwanted memories, either consciously or unconsciously. [1] It is an example of a defence mechanism, since these are unconscious or conscious coping techniques used to reduce anxiety arising from unacceptable or potentially harmful impulses thus it can be a defence mechanism in some ways. [2]
In addition to its effects during the encoding phase, emotional arousal appears to increase the likelihood of memory consolidation during the retention stage of memory (the process of creating a permanent record of the encoded information). A number of studies show that over time, memories for neutral stimuli decrease but memories for arousing ...
Difficulty creating recent term memories is called anterograde amnesia and is caused by damage to the hippocampus part of the brain, which is a major part of the memory process. [8] Retrograde amnesia is also caused by damage to the hippocampus, but the memories that were encoded or in the process of being encoded in long-term memory are erased [8]
Poor sleep is a risk factor for cognitive issues such as memory loss. ... to all sorts of problems and can cause serious harm ... memories of these experiences — i.e. move them into the long ...
The memory is stored in long-term memory, but access to it is impaired because of psychological defense mechanisms. Persons retain the capacity to learn new information and there may be some later partial or complete recovery of memory. Formerly known as "Psychogenic amnesia".
Issues in memory can also be linked to several common physical and psychological causes, such as: anxiety, dehydration, depression, infections, medication side effects, poor nutrition, vitamin B12 deficiency, psychological stress, substance abuse, chronic alcoholism, thyroid imbalances, and blood clots in the brain.
The hippocampus regulates memory function. Memory improvement is the act of enhancing one's memory. Factors motivating research on improving memory include conditions such as amnesia, age-related memory loss, people’s desire to enhance their memory, and the search to determine factors that impact memory and cognition.
