DETAILS

SYSTEM OVERVIEW

The Schuhfried VTS enables computer-assisted application of a large number of highly diverse psycho-diagnostic tests and measuring procedures. In developing the system much emphasis was placed on transparent structure and largely uniform design. It is therefore simple to operate and easy to understand and does not require any special computer skills.

The VTS basic module is required for administration of any of the available tests.

The Schuhfried VTS supports the administration of both single tests and test batteries. Many of the single tests are available in different test versions. These test versions may differ, for example, in terms of test duration or difficulty or may be parallel forms. They are characterized by different parameters reflecting specific test requirements. They have been designed for administration to a specific population (e.g. psychiatric patients, children, etc.) or for special measuring purposes (e.g. repeated measurements). Test batteries are compiled from the available single tests and test versions.

OVERVIEW

Enhanced version of the well-tried Pauli Test.

APPLICATION

Assessment of concentration, psychic saturation, and fatigability in mental tasks under time pressure (continuous arithmetic additions such as in the Pauli Test, but also more difficult test forms).

Main areas of application: clinical psychology, performance oriented aptitude diagnostics, occupational, and organizational psychology.

THEORETICAL BACKGROUND

The ALS, an enhanced version of Kraepelin's work and the Pauli Test, presents a respondent continuously with arithmetic additions in order to assess his / her performance over a period of time: The respondent is required to add to single-digit numbers as fast and error-free as possible for some time. The test is subdivided into time sections (partial times) allowing the test administrator to evaluate the course of the performance. The test can also be applied in a modified way. The modifications are obtained by varying the difficulty of the arithmetical problems and by including additional short-term memory tasks.This is how the test assesses fluid intelligence of the respondent.

ADMINISTRATION

The computerized administration of the ALS includes a standardized instruction and a practice phase, as well as a test phase of 20 minutes, during which the respondent is required to add as fast as possible two numbers at a time. They are displayed on top of each other on the screen. The respondent enters the results of the arithmetical problems via the keys of the panel. For the short-term memory tasks, the lower number moves up and is covered each time the respondent enters a result. Thus the respondent needs to memorize the lower number before entering the result in order to be able to carry out the next task.

TEST FORMS

3 standard test forms are available, yet providing always a result between 1 and 17.

  • S1: Pauli Test: The respondent is required to add two numbers that are depicted on top of each other. This form includes 20 timed sections of one minute each.
  • S2: Pauli Test with short-term memory task: The respondent is required to add two numbers that are depicted on top of each other, including a short-term memory task. This form comprises 20 timed sections of one minute each.
  • S7: Luxembourg form: The respondent is required to add the numbers or distract them from each other. The computer program makes sure that no numbers are chosen that would lead to a negative result. This form comprises 10 timed sections of one minute each.

SCORING

"Answered" as a measurement for the working speed, "Increase in items answered" as a measurement for the respondent's increase or drop in performance, "Error percent" and "Corrections" as a measurement for the respondent's working accuracy. The results of the partial times depicted in diagrams show the course of the performance.

RELIABILITY

Our own studies carried out with various samples show for the variables "Answered" and "Errors" split-half-reliabilities varying between r=0.91 and r=0.99. They correlate to a great extent with data from the paper-and-pencil version, for which test-retest and split-half reliabilities for the variable "Answered" lie above r=0.95, for "Errors Errors" and "Corrections" they vary between r=.68 and r=.88.

VALIDITY

In literature the assessment method of the ALS is described as sustained concentration for tasks under time pressure. This also includes personality traits such as resistance against distractions and disturbance, interferences, motivation and willpower, as well as the ability to sustain one's attention during a certain task.

NORMS

  • S1 Austrian norms N=310; Job applicants N=662, various professions Job seekers N=187 from Austria and Sweden Organic disorders N=130; Older persons N=95
  • S2 Job applicants N=105, various professions; Job seekers N=103 from Austria and Sweden; Swedish adults N=199
  • S7 Employees N=2907, various professions

TESTING TIME

Test form S1 and S2 20 minutes, test form S7 10 minutes.
