The test results showed that the returning Iraq soldiers did have less verbal memory performance as compared to pre-deployment. [59] The studies performed on the Vietnam veterans that suffer from PTSD show that there are hippocampal changes in the brain associated with this disorder.
Semantic memory is memory for facts, episodic memory is autobiographical memory, procedural memory is memory for the performance of skills, priming is memory facilitated by prior exposure to a stimulus and working memory is a form of short term memory for information manipulation. [5] [6]}
In the brain, declarative memory processes memories we are consciously aware of, whereas procedural memory processes our movements. [5] The fact that we walk inappropriately fast onto an escalator we know to be broken is evidence of motor adaptation without declarative memory.
A low-anxious test taker is able to focus greater attention on the tasks required of them while taking the test, while a high-anxious test taker is focused on their internal self, and the anxiety they are feeling. Anxious test takers do not perform adequately on the test as their attention is divided between themselves and the test.
In more severely brain-damaged individuals, the damage to the temporal lobes and the frontal lobes serves as good indication that amnesia will result. [13] Patients with more chronic forms of memory impairment showed poor performance when tested with PTA scales, making differentiation between the two types of memory impairment very difficult.
MRI of the human brain. It is usually desirable to study memory in humans because we have the ability to subjectively describe experiences, and have the intellect to perform complex and indirect tests of memory. Lesion studies allow us to reduce the neural mechanisms of memory, and results from finely constructed psychological tests can help us ...
Lightheadedness is a common and typically unpleasant sensation of dizziness [1] or a feeling that one may faint. The sensation of lightheadedness can be short-lived, prolonged, or, rarely, recurring. In addition to dizziness, the individual may feel as though their head is weightless.
Brain fog may affect performance on virtually any cognitive task. [1] As one author put it, "It should be apparent that cognition is not possible without a reasonable degree of arousal." [3] Cognition includes perception, memory, learning, executive functions, language, constructive abilities, voluntary motor control, attention, and mental speed.
