TOATEST.COM assesses the individual’s attention by evaluating four major performance indices: Attentiveness, Vigilance, Impulsiveness, and Hyper-reactivity.
Attentiveness reflects the ability to locate, evaluate, and respond to a stimulus correctly according to the task's requirements. This ability is calculated by the rate of correct responses to a target stimulus.
The Attentiveness index evaluates the user’s attentiveness to the target stimuli. Problems in this area reflect the user's inability to pay attention to his/her environment or to specific details when required to do so. To a bystander, an inattentive person might seem somewhat unfocused and detached. Such individuals might face difficulties in following what teachers say in class, comprehending complex instructions, keeping track of small changes in the environment, avoiding calculation errors, and more.
Vigilance reflects the ability to respond correctly with appropriate timing. This ability is calculated by the rate of correct responses to a target stimulus given within a specific period of time.
A person displaying bad timing might evaluate his/her environment correctly but will have difficulty responding in a timely manner to changes in the environment. In such cases, the individual might exhibit difficulties in performing tasks requiring a quick and immediate response and/or staying on schedule. Such tasks might include answering questions under time constraints (even though the material is familiar).
Timing problems may cause time gaps to be formed while performing tasks, as the person has difficulty keeping track and responding in time and is therefore unable to keep up with the required pace. The gap may keep growing as the task proceeds until it becomes impossible to continue performing the task properly.
Impulsiveness is the tendency to respond at a point in time, which is defined as ‘forbidden’. This tendency is calculated by the rate of responses to a non-target stimuli and is classified as 'commission errors.'
Impulsivity is described as rapid, unplanned reaction to internal or external stimuli with little forethought of the consequences. The response will most often occur before the individual has fully evaluated the situation at hand. An impulsive person might act without considering the circumstances or the possible outcomes of his/her behavior. This might take place despite the full understanding of the problematic and undesirable outcomes of such behavior. In many cases, impulsive people might not begin to monitor their performance until after their initial response. Typical features of impulsiveness include difficulty in waiting for a turn or engaging in dangerous behavior without considering the consequences
Hyper-reactivity reflects a difficulty in efficient regulation of motor responses and in refraining from unnecessary or undesirable actions. This index is calculated by the rate of excessive responses to any target and non-target stimuli.
Hyper-reactive behavior will usually be accompanied by incorrect and unwanted motor responses. This may be reflected as constant moving and restlessness, including excessive talking, difficulty in waiting for one’s turn, and inability to engage in quiet activities. The focal point of the problem is the great difficulty involved in refraining from superfluous activities, despite the person's awareness of the damage that this behavior might cause.
