Directed attention, or voluntary attention, requires a great deal of concentration and focus, and is employed in tasks such as problem solving. This type of attention employs the inhibitory mechanisms of the brain, which help block incoming stimuli that are unrelated to the task at hand. [ 11 ]
It is the selective concentration on discrete information, either subjectively or objectively. William James (1890) wrote that "Attention is the taking possession by the mind, in clear and vivid form, of one out of what seem several simultaneously possible objects or trains of thought. Focalization, concentration, of consciousness are of its ...
Central nervous system fatigue, or central fatigue, is a form of fatigue that is associated with changes in the synaptic concentration of neurotransmitters within the central nervous system (CNS; including the brain and spinal cord) which affects exercise performance and muscle function and cannot be explained by peripheral factors that affect muscle function.
Attentional control, commonly referred to as concentration, refers to an individual's capacity to choose what they pay attention to and what they ignore. [1] It is also known as endogenous attention or executive attention. In lay terms, attentional control can be described as an individual's ability to concentrate.
Attention is the process by which a concentration is focused on a point of interest, such as an event or physical stimulus. It is theorized that attention toward a stimulus will increase ability to recall information, therefore enhancing memory. [ 43 ]
In modern psychology, vigilance, also termed sustained concentration, is defined as the ability to maintain concentrated attention over prolonged periods of time. [1] During this time, the person attempts to detect the appearance of a particular target stimulus.
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.
Many different tests on attention span have been used in different populations and in different times. Some tests measure short-term, focused attention abilities (which is typically below normal in people with ADHD), and others provide information about how easily distracted the test-taker is (typically a significant problem in people with ADHD).
