Problems solved by technology

[0004] At present, although meditation and computer-based games have been developed for attention training, these methods have shortcomings, they may cause mental exhaustion and visual fatigue, or require months of face-to-face teaching by trained experts. There is no targeted research on visual sustained attention, and vision is usually used to receive more than 80% of the information, which makes the research on visual sustained attention more urgent and significant
Furthermore, these current attention trainings often do not provide feedback and the training effects are not quantified

Embodiment 1

[0037] After long-term research, the applicant found that the sensory motor system has neural plasticity, and that tactile training can transfer across channels to improve young people's visual sustained attention. attention.

[0038] According to a preferred embodiment of the present invention, based on the above research findings, a visual sustained attention training and testing system is provided, which includes a visual sustained attention training device and a visual sustained attention testing device.

[0039] Preferably, the visual continuous attention training device includes earmuffs, eye masks, tactile sensors, pressure sensors, finger vibrators, neck vibrators and computers. The middle finger continues to press the tactile device for a predetermined time, and the force is kept within a predetermined range, and the computer is used to control the vibration of the neck vibrator or the finger vibrator respectively according to whether the pressure value of the finger ...

Embodiment approach

[0044] According to yet another preferred embodiment of the present invention, the neck vibrator or finger vibrator is used to apply and input tactile signals to the trainer during the vibration process.

[0045] According to another preferred embodiment of the present invention, the visual sustained attention training device transfers and trains visual sustained attention across channels through closed-loop tactile training.

[0046] According to another preferred embodiment of the present invention, the continuous attention response test unit includes a target stimulus test module, a non-target stimulus test module and a probe question test module.

[0047] According to another preferred embodiment of the present invention, the target stimulus test module is used to randomly display numbers 1 to 9 on the computer screen, and collect the tester's keystroke data under the condition that the tester is only pressed when he sees the target number 3 When the non-target stimulus te...

Embodiment 2

[0075] On the basis of Example 1, this example aims to further verify relevant research results.

[0076] According to a preferred embodiment of the present invention, a method for training sustained visual attention is provided. The method is based on pure tactile stimulation and tactile feedback, and can be used to improve the sustained visual attention of young people. Simultaneously, the present invention comprehensively applies behavioral and electrophysiological (128-lead EEG) techniques to quantify the training effect of visual sustained attention. First of all, before training (the first day), design the Sustained Attention Response Test (SART)) and mathematical operation tasks to test the visual sustained attention level of the subjects; secondly, apply the attention training device (system) to the subjects (test or) for a period of 5 days (the second day to the sixth day) of attention training; then, after the training (the seventh day), the subjects were subjected t...

Abstract

A visual sustained attention test device, comprising a mathematical operation task test unit, a sustained attention response test unit, an electroencephalogram acquisition unit and an analysis unit, the electroencephalogram acquisition unit is used to collect testers in the visual sustained attention test During the EEG data, the analysis unit acquires the brain activations of the prefrontal cortex and the sensorimotor cortex according to the EEG data, and the brain activations are used to characterize the visual sustained attention of the tester. The device can make the test result of visual sustained attention more objective.

Description

technical field [0001] The invention belongs to the field of visual sustained attention test, in particular to a visual sustained attention test device and method. Background technique [0002] Visual sustained attention is critical for higher-order cognition and real-world activities. Nowadays, the life of young people is full of media multitasking like using mobile phones, computers, etc. Studies have shown that excessive media multitasking will affect people's visual sustained attention function to a certain extent, such as leading to decreased attention control ability, easy distraction, frequent mind-wandering, poor self-satisfaction and poor academic performance. Faced with media multitasking and numerous attention challenges, studies have shown that up to 43% of young people tend to use prescription stimulants to improve visual sustained attention and improve academic performance. However, substance abuse can lead to complications (such as depression) and even life-...
