Benton Visual Retention Test Device and method based on reaction

Abstract

The invention discloses a Benton Visual Retention Test Device and method based on reaction. The device comprises device hardware equipment and detection device software, wherein the hardware equipment of the device comprises an upper computer, a single-chip microcomputer processor, keys, a Bluetooth module, a light source, a liquid crystal panel and a storage module. The liquid crystal panel converts the stimulation image into liquid crystal pixels, and presents a stimulation image to a tested object after receiving the irradiation of the light source; the single-chip microcomputer processor is used for receiving various instructions and controlling corresponding equipment modules to perform corresponding actions; the upper computer is an operation platform of detection device software; the detection device software comprises control software, single-chip microcomputer software and data management and analysis software. The invention also discloses a method for carrying out the Benton Visual Retention Test. According to the invention, by measuring the memory time threshold and the response time of the subject, the quantitative evaluation of the response ability of the subject is realized, and the method can be used for analyzing the rehabilitation conditions of test crowds facing different educational levels and brain impaired patients.

Description

technical field [0001] The invention relates to the field of biomedical engineering, in particular to a reaction-time-based Benton visual maintenance test device and method. Background technique [0002] Benton Visual Retention Test (Benton Visual Retention Test, VRT) was compiled by Arthur L. Benton in 1955. It is a simple and quick short-term memory test method. The Benton visual retention test was originally used to evaluate short-term memory and visual motor function, and has been widely used in the research of visual perception, visual memory, and spatial structure ability after brain injury. The traditional Benton vision retention test is implemented in a form similar to a questionnaire. The examiner sits opposite to the subjects, the examiner distributes drawing paper and pencils to the subjects, and then gives stimulus cards with irregular graphics (same as drawing The same size of paper) was presented to the subjects for a fixed time. After a fixed time interval, t...
