Störeffekten

Störeffekten, often translated as the "disturbance effect" or "interference effect," is a concept that describes how the presence of one stimulus or event can negatively impact the perception or processing of another. This phenomenon is not limited to a single sensory modality but can occur across different senses and cognitive processes. In visual perception, for instance, a distracting visual element can make it harder to focus on a target image, a phenomenon closely related to visual clutter. Similarly, in auditory perception, background noise can mask or interfere with the understanding of speech or other desired sounds.

Beyond sensory input, Störeffekten also applies to cognitive tasks. The presence of irrelevant information or competing thoughts can impair performance on a primary task, a concept explored in research on attention and working memory. This interference can manifest as slower reaction times, increased errors, or a reduced ability to retain information. The strength of the Störeffekten is often dependent on the nature of the interfering stimulus, its similarity to the target stimulus, and the cognitive load of the task at hand. Understanding this effect is crucial in fields such as human-computer interaction, where designers aim to minimize distractions, and in educational psychology, where creating optimal learning environments is paramount.
