... found that participants could estimate the amount of objects (beans randomly dispersed on a tray) accurately until 8 beans, after which there would be errors in judgement. This ability to observe the correct amount of objects until about eight has been defined as 'subutizing'. (Folk et al (1988).) Accuracy is still reasonable above eight, according to Woodworth and Schlosburg, who found that there were different factors that could affect the accuracy of object estimation. These processes would predict the amount of objects presented without counting them. So even though amount of objects could be large or small, the processes can perceive to make a rough estimation. Other factors do affect the accuracy of the estimation. Experiments found that the density of the distribution of objects affects the estimation of the objects. Participants viewed circles, either filled or empty, randomly arranged, and were asked to predict the number of filled circles. When the ...
