The preparation of written test memory span groups

Key words short Digit span test performed with paper and pencil in groups WANG JinLi, ZHANG YueJuan 1Department of Medical Psychology, Medical College of Chinese Peoples Armed Police Force, Tianjin 300162, China, 2Hebei Normal University, Shijiazhuang 050091, China 【Abstract】 AIM: To change digit span test in Wechsler Intelligence Scale from individual test to group test. METHODS: The test form of digit span was changed from oral test to paperpencil test. In order to ensure the standardization of answer time, the action of uniform pencillifting with the emergence of digits was added into test program. The total of subjects was 884. RESULTS: The testretest coefficient was 0.658, and the correlation between group test and individual test was 0.581. There was a significant correlation between the group test and other subtests of other intelligence scales such as number series, words test, calculation test, spatial ability test , tap speed test and drawing circle test. The scores of the 2 groups with different education level were significantly different (P <0.01). CONCLUSION: It is feasible to change the digit span test in Wechsler Intelligence Scale from individual test to group test. 【Keywords】 digit span; group test; memory, shortterm Abstract Objective: To change the test method, the Wechsler intelligence tests in the digit span test to change into a group of individual paper pen test. Method: the digit span test and an oral answer way into writing mode, when in answer to increase lift pen action program to achieve additional time allowed for standardization. Surveying the sample to 884 people. Results: The test-retest reliability 0.658; digit span test groups compatible with the validity of individual tests is 0.581, and the Wechsler intelligence test text test, numerical reasoning, calculation tests, spatial tests, attention tests, speed tests RBI tests have low attainment was significantly associated (P < 0.01), the distinction between different education groups were significant (P <0.01). Conclusion: The change in the number of Wechsler intelligence tests breadth of test methods to test the use of individual tests as a group is feasible. Key words digit span; group test; memory; short 0 Introduction short-term memory for the 1.5 s to 1 min of memory [1], human work is important, is the intellectual component. on the short-term memory span test measuring a text [2], digit span test and in-kind images span test, the most famous is the Wechsler Intelligence Tests digit span test [3 ]. in the form of individual written test, memory test battery, and intelligence test battery which has some short-term memory tests [4], but not in the group test in the form found in the short-term memory test. For example, the group used This is a weak group ability tests. In literature, the capacity of the memory test when the group is still blank. In view of this, we Wechsler Intelligence Test for digit span test is modeled to change the measuring method of operation, make it a group test. 1 object and method 1.1 Object cluster sampling method of a mobile division in the armed police taking 825 soldiers, all male, aged 19 ~ 29 (21.0 ± 2.6) years. of which two squadrons 56 subjects were separated by 9 d after the retest; on the other two squadrons of 43 subjects were separated by 3 d after the original scale with the Wechsler Digit Span to do individual tests. Medical College of Armed Police Force 59 cluster sampling, to do different cultural groups other controlled study. 1.2 Methods Wechsler intelligence test subjects digit span subtest [4], using self-set answer sheet. operating procedures: first, the main test instruction subjects held the pen in the air, so the main probation and issued a set of numbers group topics. held the pen in the air to prevent the subjects to put pen to paper in advance of the time interval. to show the speed of a number per second, the main test subject after reading the interval 1.5 s hair ~ 40 812 copies of an effective paper. The study did not Daobei digital parts. The first question four figures recorded 4 points, after each question, plus 1 for each additional number of points, final score is the number of test subjects through the longest . Statistical analysis: All data x ± s, said, with the SPSS l0.0 software to the relevant analysis methods for statistical analysis.

2 results 2.1 confidence level of the two squadrons of 56 subjects, the initial test score of 7.11 ± 1.10, separated by 9 d after the retest, re-test score of 7.53 ± 1.42, the correlation coefficient of two measurements 0.66. 2.2 Validity 2.2.1 compatibility order to investigate the validity of test groups and the Wechsler Digit Span test the compatibility of individual validity, we have 2 other squadron do groups of 43 test subjects, score 7.11 ± 1.10, after 3 d apart with the Wechsler Digit Span scale to do the individual test score of 7.81 ± 1.20. 43 groups were administered the digit span Wechsler digit span test scores and individual test scores The correlation coefficient is 0.58. organizations to examine the digit span test compatibility with other ability test validity, we have the digit span test scores and other ability tests (n = 825) scores do related, the results showed: digit span test scores numerical reasoning, writing tests, computing, space, dot speed and ability to draw a circle so the correlation coefficient test scores, respectively, 0.146, 0.168,[link widoczny dla zalogowanych], 0.295, 0.130, 0.175, 0.104 and 0.028. In addition to circle test, the digit span and other capacity tests were significant levels (P <0.01). 2.2.2 In order to investigate discriminant validity test of digit span groups discriminant validity of different groups, we cadets scores (n = 59) and other Warrior scores (n = 800) were compared, results showed that cadets and soldiers of the average score was 8.73 ± 1.33 and 7.16 ± 1.50, t test after significant difference (P <0.001). 3 discussion 3.1 change in test methods to change the digit span test ways to write an oral answer, and in the sampling procedure were required to arm in the air, time to put pen to paper in accordance with uniform answer, this action the main test program to observe and control each well was tested in the arm movements to control the answer time, to prevent the subjects answer in advance. from testing 884 in the actual situation entirely workable, you can do standardized tests to groups. reliability and validity test results also support this conclusion .3.2 reliability of the original test reliability of 0.66 ~ 0.89 [5], the test level of reliability to the original test, under normal circumstances, the same test group Surveying reliability testing facilities should be lower than the individual, the test can achieve the lower limit of the original test is reasonable. 3.3 Validity of Digit Span test associated with the original test group was 0.58, confirming that the test measured with the original test basically the same memory. oral answer and document the way it should be different way of answer, may be slow to write the figures in the write back has been forgotten, it is not very high correlation coefficient is reasonable. from the digit span test and other intellectual subtests relevant to see, in addition to tests outside the circle, have reached a significant level, but the index is low, which is the original set of tests in the Wechsler adult intelligence test in the same situation. circle tests are tests of motor ability, and memory test There should be no correlation. in the investigation of different groups, the undergraduate students scored significantly higher than the ordinary soldier, that tests to distinguish between groups of different educational levels, which GarciaMorales [6] The method of digit span test of individual research results. 【Reference】 [1] Lev.
