TUS 6/9. ATTENTION AND PERCEPTIVENESS TESTS (TUS) VERSION 6/9 – NORMS FOR ADULTS

This publication is an appendix to the TUS handbook published in 2006. Attention and Perceptiveness Tests were presented to test-users in 2006 and since then have never ceased to be a bestseller. The tests have a shared subject which is attention and perception. The package includes four tests in each of which different stimuli have been used. In two of them the stimuli are numbers (versions 6/9 and 3/8), in one they are letters (version b/k) and in still other one – visual signs resembling an asterisk (version gw). Each test underwent a separate normalization procedure and this makes all of them totally different asessment tools. Thus each test can be used separately.

In the assessment of adults test users usually apply the TUS version in which number 6 and 9 are crossed out – that  is why this version was normalized again. In the normalization study a sample  of 992 persons aged 20-80 was used. The study was conducted from February to July 2015 and covered all the voivodeships in Poland.

The present publication includes informations concerning the normalization study. All other elements such as conceptual assumptions, a description of the method and of the administration procedure as well as details concerning score calculation were left out. As in the previous normalization test results are defined with the help of three indices:

• Perception speed (SP) – refers to how quickly a human being is able to browse through perception  material. Calculation of the index is based on the last sign browsed, no matter correct or incorrect. The higher the index, the faster the perception.
• Number of mistakes – measures unreliability of perception and informs about an ability to differentiate perception material. It is developped by calculating the number of signs which were erroneously crossed out. The higher the index the less reliable the perception.
• Number of omissions – measures unreliability of attention and informs about an ability to perceive important stimuli. It is the number of signs, from among all those browsed, which should have been crossed out but were not. The higher the value the stronger the tendency to omit important stimuli.

The internal stability values are all very satisfactory in the case of the Perception speed index. In the case of the Number of omissions index correlations are lower. For both indices no important differences were ascertained between the first and the second study. This proves that the test is resistant to learning factors. It can be applied for research purposes as well as in the qualification procedures for positions which require attention.
