When a test is completed, the data can be automatically processed and printed out. At the same time, it is also designed with the function of rehabilitation training, any item can be selected according to the clinical needs of the training time or number of times specified.
Tests focus on audio-visual simple response tests, audio-visual selective response tests, audio-visual attention allocation tests, frequency of movement tests, memory tests and training, numerical symbols tests or decoding tests, connectivity tests, which can also be called visual quality attention allocation, stability tests and training, and discriminative reflection experiments.
II. Test items:
1. Audio-visual simple reaction time test.
Tests of eye, ear, hand, and brain reactions and reaction speeds to understand the actual and potential abilities of the subject and to assist in the diagnosis of dysfunctional decline or retardation.
There are two types of tests: a visual simple reaction time test and an auditory simple reaction time test.
2. Tests on audio-visual selective response.
The test of a subject's ability to differentiate and select the speed of response can be used to understand the subject's lateral dominance, i.e., to examine the dominant hemisphere of the brain.
Includes a visual 覚choice response time test and an auditory choice response time test.
3. A test of visual and auditory attention distribution.
It is a test and training program that examines human visual, auditory, and attentional distribution, and is used to understand and change the coordination of movement, learning process, and fatigue.
This is an attention allocation test that requires the participant to use both the left and right hand simultaneously with sound and light stimuli, with three types of sounds and adjustments to increase the level of difficulty. The Q-value (attention allocation value) is calculated by the computer and printed out directly.
4. Frequency of movement test.
This test, also known as the Finger Tapping Test, is one of the essential neuropsychological tests and is a sensory-motor test that examines the fine motor skills of the hands of the participant in order to provide an indication of the pathology of a brain injury, as well as an effective method of training for rehabilitation.
The test is designed to be hand-friendly, foot-friendly, hand-crossing, foot-crossing, and hand-foot-crossing, so that you can choose the test items according to your needs.
5. Memory testing and training.
In clinical practice, memory impairment is an obvious symptom of many neuropsychiatric disorders, which needs to be identified by objective methods. In education, talent selection and many industries, objective methods are also needed to identify memory ability, and in rehabilitation medicine, memory test is indispensable for the diagnosis and treatment of patients as well as for the assessment of the effect of rehabilitation, and it is also a test of attention, observation ability, and instantaneous memory, which can be used to judge and study the degree of brain damage, dementia, mental retardation and other problems. It is also a test of attention, observation and instantaneous memory, and is used to determine the extent of brain damage, dementia, mental retardation and other problems.
Tests include: "Tests of Deficit Memory," "Tests of Short-Term Memory," "Backwards Counting," "Counting by 3′s," as well as Numerical Breadth Tests, Visual Memorization Test". The test items can be selected at any time on the keyboard, and the time and level of difficulty can be adjusted for testing or rehabilitation training.
6. Tests on digital symbols or decoding tests.
This test is designed to measure general learning and associative abilities, visual and motor fine motor skills, perceptual discrimination and dexterity, as well as persistence and speed. It is a sensitive test for measuring the impact of brain damage in adults and children.
7. The link test can also be called the visual quality attention allocation.
This is a test that examines vision, concepts and visual-motor tracking. There are two types of tests: Type A and Type B, with Type B being more difficult than Type A. The Type A test is generally considered to show the functioning of the right hemisphere. Style A is generally considered to be a test of the right hemisphere, reflecting more primitive perceptual-motor rates. Type A is generally considered to reflect the right hemisphere's functioning, i.e., the more primitive perceptual-motor rate, whereas Type B is considered to reflect the left hemisphere's functioning, and includes conceptual and attentional shifts in addition to perceptual-motor rate. This test is simple to administer, sensitive to diffuse and lateralized brain damage, and useful in screening for frontal lobe dysfunction.
We have designed a variety of permutations and combinations so that it is not easy for subjects to plan in advance, and the results are scientific and reliable.
8. Stability tests and training (or arm stability tests).
It is an important parameter closely related to physiology, psychology and pathology of the human body, and is extremely relevant to attention, emotion, fatigue, and higher and lower nervous activity. Therefore, it is often required in the treatment, research, and rehabilitation of neurological disorders, psychiatric disorders, geriatric disorders, pediatrics, and traumatic hand injuries and other disorders resulting in a decrease in the function of the hand. Therefore, it is often required in the treatment, research, and rehabilitation of various diseases that cause hand function decline.
9. Identification reaction experiments.
This test is often used in experiments in motor psychology, but in recent years it has also been used in neuropsychological tests, as well as in rehabilitative psychological training, where it examines the discriminative reactions and motor coordination of the brain, eyes, hands, and feet by means of prescribed colors, lights, and keys.

V. Reasons for recommendation
In the clinic, the subject's eye, hand, ear and brain reaction ability and reaction speed can often cooperate with the counselor or physician to find out the potential dysfunction with the diagnosis of functional deterioration or retardation, through the test and training of human visual, auditory and attention allocation to change the coordination of recognized movements to alleviate fatigue phenomenon in the learning process, and through the sharp hand, sharp foot and other tests for the cases with brain damage to provide effective rehabilitation training. It also provides effective rehabilitation training for cases of brain damage through tests such as the sharp hand and sharp foot, and tests on attention, observation, and instantaneous memory to help determine the degree of brain damage, Alzheimer's disease, mental retardation, and neurological disorders. It is a very practical psychological experiment and rehabilitation equipment.
Attention allocation is the ability of a person to direct attention to two or more activities or objects at the same time. It is a kind of ability of people to adjust their attention according to the needs of the current activity, which is fundamentally different from attentional distraction. Its realization depends mainly on whether it has the skillful ability, that is, at the same time in two or more than two kinds of activities, there can only be a kind of rusty, need to focus attention, while the rest of the action must be quite skillful in the edge of the attention can be accomplished. In addition, the simultaneous activities must be performed in different organs of the human being, otherwise it is impossible to realize the dual or multiple use of the mind.
The level of attention allocation depends on the complexity of the nature of the simultaneous activities and the level of individual proficiency. Usually, several simultaneous activities are intrinsically related to each other, are in a neighboring space, have a low level of complexity, and have a level of individual proficiency that facilitates the allocation of attention; otherwise, attention is difficult to allocate.
This instrument measures the magnitude of the attention distribution of the subject, i.e., it examines the subject's ability to perform two tasks at the same time. This instrument can also be used to study the movement, learning process and fatigue phenomenon. It can be widely used in the fields of learning, sports and transportation, etc. It is suitable for psychological teaching experiments in all kinds of colleges and universities.
