Bourdon test with numbers-online
In fact, the digital version of the Bourdon test can be the simplest of all the variants of the Bourdon test - since numbers are easier to perceive than, for example, letters or rings with a certain direction of the gap, but this does not in any way reduce the possibilities of this type of Bourdon test for assessing the possibilities of our attention.
Instructions for performing the test Bourdon's test digital version - online:
The task of the test subject when performing this form of Bourdon's test is to, sequentially looking through row by row of the table with numbers, find and highlight those numbers that were given in the assignment. It can be either one number or two, depending on the test variant. The time to complete the test is slightly less than for most types of proofreading tests, namely 3 minutes. In case you cope with the task earlier, click on the "Submit" button.
Correction test calculated indicators:
Bourdon test calculated indicators:
Time spent t
The total number of characters viewed up to the last selected character N
Total number of lines viewed C
The total number of characters to be crossed out n
The total number of characters crossed out M
Correctly selected letters S
Letter characters you missedP
Wrongly selected characters O
Calculation of the result:
Indicator of the speed of attention (attention performance) A=N/t A characters per second.
Work accuracy indicator (first option) T1=M/n T1 conventional units
Work accuracy indicator (second option) T2=S/n T2 conventional units
Work accuracy indicator (third option, according to Whipp) T3=(M-O)/(M+P) T3 conventional units
Mental productivity index E=N*T2 E characters.
Mental performance Au=(N/t)*((M-(O+P))/n) Au characters per second
Concentration (percentage of correctly highlighted characters from all that needed to be highlighted) K=((M-O)*100)/n K percent.
Indicator of stability of attention concentration Ku=C*(C/(P+O+(1))) (if there are no errors or omissions, add one to the divisor) Ku conventional units
The capacity of visual information (V) calculated by the formula: V=0,5936*N where 0,5936 - average capacity per character (bit) V characters
The processing rate (Q) is calculated by the formula: Q=(V-2,807*(P+O))/t where 2,807 - loss of information for one missed one, Q characters
Attention level K.
|The level of development of concentration of attention||Value, K%|
|Very good||81 - 100%|
|Good||61 - 80%|
|Average||41 - 60%|
|Bad||21 - 40%|
|Very bad||0 - 20%|
