The Task Interference Model of Crowding

  • Robert B. Bechtel
Part of the NATO Conference Series book series (NATOCS, volume 10)


The recent problems of defining crowding are discussed with the suggestion that a more workable definition can be derived from the early animal studies. A task interference model is proposed that can be used in either animal or human studies. This model is compared with three other models used in crowding studies and has some overlap. The main problem with the model is to empirically define the seriousness of crowding effects on the various tasks of human behavior. Crowding that interferes with reproductive tasks is potentially the most serious. This is followed by crowding that affects sustenance tasks.
