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

Objective and precise measurement of the visual field of perception.

APPLICATION

This test was designed to assess the perception and processing of peripheral visual information.

Main areas of application: traffic psychology, pharmacology, aviation psychology, sports psychology, industrial, and organizational psychology.

THEORETICAL BACKGROUND

A good visual perception is indispensable for many activities conducted by humans and machines together, such as steering a motor vehicle. A driver perceives over a 90% of information via the visual channel. Literature about visual aspects of driving usually mentions peripheral visual perception in connection with three functions:

  1. Speed estimation (high angular velocity in the peripheral visual field).
  2. Steering a car (through objects that pass by at the sides of the road).
  3. Observance of the surroundings (by detecting incidents and objects, e.g. cars turning in from another road, or passing). The PP made possible to design a purely behavior-related instrument that meets high methodical demands.

ADMINISTRATION

Light stimuli - produced with the light emitting diodes mounted onto the device - move along with a pre-set speed (in regular "jumps"). Critical stimuli appear in pre-set time intervals, to which the respondent has to react by pressing the foot pedal.

TEST FORMS

There is one test form.

SCORING

The following variables are recorded:

  • Field of vision
  • Visual angles left / right
  • Tracking deviation
  • Hits left / right
  • Incorrect reactions
  • Omitted reactions
  • Median reaction time (left / right stimuli)

RELIABILITY

Studies to prove the reliability of this test have not yet been conducted.

VALIDITY

Context-logical validity or a high self-evident validity can be assumed. Critical stimuli are presented in the visual field of the respondent to which he / she has to react as quickly as possible just like for instance in road traffic.

NORMS

Norms of N=360 adults are available for the variables Field of vision and Tracking deviation.

TESTING TIME

The time required for the text is approximately 15 minutes (including the instruction and practice phase).
