As absolute impression is known in the psychology of perception one on the sensory perception based subjective impression of the quantitative properties of an object or view object. The determination of the ability to perceive is the basis for further investigations. Such an impression is therefore not derived from a comparison sample or a scale, for example a ruler .

Concept formation

The formation of the term goes back to the observation that test subjects ( test subjects ), after having reached a certain level of familiarity with a set of objects, are able to make judgments about the extent of a quantifiable property without comparison with a standard object.

The absolute impression and the absolute assessment derived from it has become an essential part of psychological scaling tests. It is required that classifications be made in a category estimation scale, the categories of which are formed, for example, by the following judgments:

• tiny
• small
• medium
• big
• very large

Such tests show that the absolute impression can be significantly deceiving . Examples include the Moon illusion , numerous other hallucinations like the optical illusion and the fact that many people do not have a perfect pitch have. This means that the absolute impression depends on the type, form of presentation and sequence of the effective environmental conditions or objects as well as before the specific task.

Absolute impressions and judgments depend on the class affiliation ( intension ) of the objects to which they refer. A dog the size of a large cat will e.g. B. judged as small because of its belonging to the class of dogs .
