Detailed Description+

The test combination Perception and Attention Functions - Short Test (WAF-KT) measures fundamental subfunctions of attention and corresponds to the standard testing (short form) of the WAF VTS tests.

Attention performances are important for the successful handling of the tasks that the individual encounters in daily life. They are not independent of other skills but are a constituent of many processes of perception, memory, planning and acting, spatial orientation and problem-solving. Attention functions are thus basic skills that are required in almost every practical or intellectual activity. Many neurological and psychological disorders and diseases have an adverse effect on different aspects of attention performance. The WAF tests, which are model and guideline compliant (GNP), are therefore mainly used in the context of clinical neuropsychological investigations since they allow for both a global and a differentiated assessment of an individual’s strengths and weaknesses. They are also used for personnel selection (especially in the field of manufacturing & safety assessments) and for traffic psychological investigations. 

The WAF-KT test combination was compiled with the objective of allowing for testing that is as economical possible in terms of time for measuring attention performances. With two subtests on the subfunctions alertness and divided attention, it includes a subtest each on intensity and selectivity of attention.

Validation+

The subtests of the WAF fulfill the requirements for content and construct validity. Since all subtests contained in WAF are measured using common and widely used paradigms, content validity is given. Construct validity can be confirmed via the analysis with construct-related and construct-unrelated tests. In addition, confirmatory factor analyses prove the factor structure based on different samples corresponding to common attentional models.

Scoring+

The scoring of the test combination corresponds to the individual scoring of the WAF VTS tests and includes the possibility for norm adjustment as well as scoring follow-up assessments in addition to reporting the main and subsidiary variables. The following main variables are scored, depending on the subtest:

  • A main variable with the name of the ability it measures is available for each dimension. These variables are a logarithmic mean of the individual reaction times for tasks on alertness or divided attention.
  • Measure of dispersion of reaction time: Measure of the variability of the respective attention function.
  • Different error types: Measure for sustaining the corresponding attention function.

Additional information:

  • Norm adjustment: The impact of age, gender, and education is automatically considered in the scoring.
  • Display and scoring of follow-up assessments in a compact overview.
