Attention span is the amount of time spent concentrating on a task before becoming distracted. [1] Distractibility occurs when attention is uncontrollably diverted to another activity or sensation. [ 2 ]
The exponential function in parentheses corresponds to the fraction of total change that has been achieved as time passes and the difference between C ss and C 0 equals the total amount of change. Finally, at steady state, the concentration is expected to equal the rate of synthesis, production or infusion divided by the first-order elimination ...
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 ...
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.
Mastery learning is an educational philosophy first proposed by Bloom in 1968 [8] based on the premise that students must achieve a level of mastery (e.g., 90% on a knowledge test) in prerequisite knowledge before moving forward to learn subsequent information on a topic. [9]
Iron rusting has a low reaction rate. This process is slow. Wood combustion has a high reaction rate. This process is fast. The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time. [1]
Therefore, it is valid to apply the steady state approximation only if the second reaction is much faster than the first (k 2 /k 1 > 10 is a common criterion), because that means that the intermediate forms slowly and reacts readily so its concentration stays low. The graphs show concentrations of A (red), B (green) and C (blue) in two cases ...
A second-order stimulus is a type of visual stimulus employed in psychophysics where objects are distinguished from their backgrounds through variations in contrast or texture. In contrast, a stimulus distinguished by differences in luminance is termed a first-order stimulus.
