DT Determination Test

Application

Assesses reactive stress tolerance, attention and reaction speed in the respondent.
The Determination Test is a complex multi-stimuli reaction test involving the presentation of both colored stimuli and acoustic signals to which the respondent reacts by pressing the appropriate buttons on the response panel and using the foot pedals. The stress element of the DT arises from the need to sustain continuous, rapid and varying responses to rapidly changing stimuli. Because test presentation is adaptive, any individual can be confronted with stimuli at a frequency sufficiently high to place him in a situation in which he is over-challenged and can no longer execute the necessary responses. The DT can therefore be used to investigate behavior under various levels of psychophysical stress. The test is used in recruitment for positions with safety-related requirements (safety assessments), in staff development, in clinical neuropsychology, in traffic psychology and in sports psychology.

Administration

Respondents react as quickly as they can to optical or acoustic stimuli by pressing the appropriate buttons on the response panel or using the foot pedals.

Test forms

S1: Short form with adaptive stimulus presentation (all stimulus types)
S2: Long form with adaptive stimulus presentation (all stimulus types)
S3: Free stimulus duration (colors and tones; Rostock Form)
S4: Combination of free and fixed stimulus duration (Hanover Form)
S5: Fixed stimulus duration (all stimulus types; Vienna Form A)
S6: Fixed stimulus presentation (colors; Vienna Form B)

Scoring

The following main variables are scored, depending on the test form:

  • S1 and S2: Correct – Number of appropriate reactions (both on-time and delayed)
    • Measure of the respondent’s capacity and resilience in reacting quickly and appropriately in reaction chains.
  • S3 – S6: Median reaction time – reaction mode (in seconds) from the start of stimulus presentation until a button is pressed.
    • Measure of the ability to react quickly (S3, S4/Subtest 1)
    • Level of the ability to react appropriately to tasks over a lengthy period and under stress (S4/Subtest 2, S5, S6).

Personalized Word report

An answer matrix shows the reactions given, categorized according to the type of stimulus (colors, tones, foot). It provides detailed information about the type and number of responses actually made to the given stimuli. This can be used to investigate whether a higher than average number of problems arose in connection with a particular stimulus.
