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

The simplified but efficient design of the items makes it possible to assess the individual long-term attention without disadvantaging respondents with a weaker performance.

APPLICATION

Assessment of the long-term selective attention and concentration ability, general performance and commitment; applicable for people 15 years of age and over.

Main areas of application: clinical psychology, occupational and organization psychology, medicine and pharmacology, aviation psychology, neuropsychology, traffic psychology, and performance-oriented aptitude diagnostics.

THEORETICAL BACKGROUND

From the beginning, attention has always been a basic term in scientific psychology. However, until today psychologists have not succeeded completely in separating the various aspects and findings related to attention and integrate them into an established theory at a time. According to a minimum definition, attention is a selection process: perception and imagination are focused and aimed at a part of the stimuli confronting a person simultaneously. The aspect continuous emphasizes that sustaining one's attention becomes more demanding when the task is repeated. Unlike vigilance, continuous attention is defined as selective awareness of stimuli that are either presented always or most of the time. Vigilance, on the other hand, requires a person to react to randomly presented stimuli just a few times over a longer period of time. For the measurement of continuous attention, the main aspects that are assessed refer to a general ability or willingness to perform well. These aspects are largely independent of intelligence.

ADMINISTRATION

Rows of triangles are shown on the screen pointing either up or down. Whenever a pre-defined number of triangles points down, the respondent is required to press the reaction button.

TEST FORMS

  • S1: Clinical form 1 (rows with 5 triangles and regular time intervals)
  • S2: Clinical form 2 (rows with 5 triangles and irregular time intervals)
  • S3: Normal form (rows with 7 triangles and irregular time intervals)
  • Forms S1 and S2 should only be applied to respondents who are expected to have an impaired attention capacity.

SCORING

The following variables are calculated: Sum correct, Mean time correct, Sum incorrect, and Mean time incorrect.

RELIABILITY

Depending on the test form and the comparison sample, coefficients for Cronbach's Alpha and split-half reliability were found to range between r=.64 and r=.99.

VALIDITY

Criterion validity is given. Sustained attention is a psycho-logical construct which refers in general terms to a prerequisite of performance that is relatively independent of intelligence and effective over relatively long periods of time. The possibility that the Sustained Attention Test requires the use of higher cognitive functions can be ruled out. The test reveals the stability of a person's long-term attentional performance as an underlying requirement of cognitive abilities under speed conditions.

NORMS

Norms of between N=297 and N=568 normal individuals are available for all test forms; in some cases the norms are also partitioned according to age and educational level. For Form S1 a norm sample of N=369 neurological patients is also available.

TESTING TIME

Between 20 and 35 minutes (including instruction and practice phase), depending on test form.
