The invention discloses a tester for measuring a weight difference threshold by a constant stimulus method. The tester comprises a bracket, wherein a wheel disk is arranged on the bracket; the wheel disk is connected with an output shaft of a motor below the bracket, and the motor is connected with a controller; a guiding groove is formed at one side of the wheel disk, and one end, far away from the wheel disk, of the guiding groove is connected with a blocking plate; a blocking plate hole is formed in the blocking plate; a plurality of grooves are formed in the wheel disk along the circumferential direction, a test block is arranged in each groove, and the test blocks are different in weight; a plurality of buttons are further arranged on the bracket and are connected with the controller; the controller is connected with an upper computer. The tester has the beneficial effects that the tester can be used for recording data automatically, so that error rate is lowered; manual replacement of the test blocks is not required during testing, so that accuracy is improved, and the intensity of labor is reduced.
Description
technical field [0001] The invention relates to the field of psychological experiment instruments, in particular to a weight difference threshold tester for constant stimulation method determination. Background technique [0002] It is one of the commonly used experiments in modern psychology to test the weight difference threshold with a constant stimulus method. It originated in 1860 when G.T. The basis for method development was laid. Fechner proposed three methods to measure sensory threshold, one of which was the constant stimulus method. The constant stimulus method is also called the right and wrong method or the number method. The measurement method is to let the subjects compare the comparison stimulus with the standard stimulus. The standard stimulus is a certain stimulus intensity felt by the subject. The comparison stimulus can be determined within a certain distance from the standard stimulus. Generally, 5-10 are selected as comparison stimuli. , presented ra...
