Alternating attention: The ability of mental flexibility that allows individuals to shift their focus of attention and move between tasks having different cognitive requirements. Divided attention: This refers to the ability to respond simultaneously to multiple tasks or multiple task demands.
Performance on these tasks is disrupted when a switch from one task to another is required. This disruption is characterized by a slower performance and decrease in accuracy on a given task A on a trial that follows the performance of a different task B ("alternating" or "switch" trial) as opposed to performance on task A when it follows another trial of task A ("repetition" trial).
Attention can be guided by top-down processing or via bottom up processing. Posner's model of attention includes a posterior attentional system involved in the disengagement of stimuli via the parietal cortex, the shifting of attention via the superior colliculus and the engagement of a new target via the pulvinar. The anterior attentional ...
Human multitasking is the concept that one can split their attention on more than one task or activity at the same time, such as speaking on the phone while driving a car. Multitasking can result in time wasted due to human context switching (e.g., determining which step is next in the task just switched to) and becoming prone to errors due to ...
The scarcity of attention is the underlying assumption for attention management; the researcher Herbert A. Simon pointed out that when there is a vast availability of information, attention becomes the more scarce resource as human beings cannot digest all the information. [6] Fundamentally, attention is limited by the processing power of the ...
The Trail Making Test is a neuropsychological test of visual attention and task switching.It has two parts, in which the subject is instructed to connect a set of 25 dots as quickly as possible while maintaining accuracy. [1]
Continuous partial attention is the behavior of dividing one's attention, scanning and optimizing opportunities in an effort to not miss anything that is going on, coined in 1998 by Linda Stone. [1] While multitasking is driven by a conscious desire to be productive, continuous partial attention is an automatic process motivated by the desire ...
Specifically, research on attentional capture has two modes: voluntary and reflexive. The voluntary mode is a top down approach where attention is shifted according to high-level cognitive processes. The reflexive mode is a bottom up approach where attention shifts involuntarily based on a stimulus's attention attracting properties. [40]
