Test "Confused Lines" (Test of interwoven lines) - a psychological technique aimed at measuring stability and concentration.
Content
Creation History
For the first time this test was proposed by A. Ree m in 1958. This test was 16 intertwined broken lines. In 1980, this technique was modified by K. K. Platonov . [1] In this modification, this technique is currently used.
The technique of “intertwined lines” is aimed at measuring the degree of stability of visual attention when it is concentrated and the effect of prolonged work on concentration.
Stimulus material
The stimulus material is 25 entangled lines that begin on the left side of the form and end on its right side. On the left side, all lines are numbered from 1 to 25. The subject's task is to track the progress of each line in order and in the cell where it ends, indicate the line number. The test subject is not allowed to use assistive devices (such as a pencil, finger) to trace the line.
Instructions
Instructions to the test subject: “Before you on the form is a row of lines intertwined among themselves. Each of them starts on the left and ends on the right. Your task is to trace each line from left to right and put down its number in the cell where it ends. You need to start from line 1, then go to line 2, etc. to the end. You need to follow the lines only with your eyes; you cannot help yourself with your fingers, with a pencil. Try to work fast and not make mistakes. ” [2]
One of the modifications of this technique is to complete the task within 7 minutes. In this case, only the number of correct answers for the set time is fixed. [3]
Data Processing and Interpretation
Processing and interpretation. When processing the results, such indicators are recorded as: total elapsed time to complete the task ( t ), number of incorrect answers - errors ( b ). According to these indicators, the concentration coefficient ( Q ) and the concentration deficit coefficient ( Dk ) are calculated using the following formulas:
Where a = 25 is the number of lines in the form, b is the number of errors (the number of incorrectly traced lines), t is the time taken to complete the task, Q is the concentration coefficient. The concentration deficit index ( Dk ) is calculated by the formula:
In the absence of attention deficit, Dk will be zero. This indicator assesses both qualitative and quantitative violations of voluntary attention. High Dk values indicate low attention span.
It also records the time during which the subject traces every five lines (from 1 to 5, from 6 to 10, from 11 to 15, from 16 to 20, from 21 to 25). The rate of completion of the task makes it possible to judge the impact of long-term work, namely, the stability of concentration attention during the long-term performance of the task. [four]
Application
The main areas of application of this test are children's psychodiagnostics ; sports psychology ; staff assessment ; determination of the individual qualities of a professional; production safety assessment. This test can be used to assess the dynamics of the functional state of the employee to assess the impact of the workload on the performance of the subject of labor. To do this, the subject passes the “Confused Lines” test before starting work, when doing work, and after it is completed.
