The Effect of Arrangement on Enumeration

To find principal factors which affect the development of enumeration, many recent researches have investigated the effect of visual characteristics on counting process. Here we have addressed the effect of arrangement on enumeration process.
37 participants aged between 18 to 30 years old were evaluated. We examined counting speed in three different arrangements of dots in five magnitudes (8-12) which differed in regularity and imaginary lattices between their dots.
According to our results, enumeration speed is affected by both arrangement and the set of magnitudes (p Taken together, these results show that lattice formation which facilitates groupitizing and subsequently subitizing, has considerable effect on enumeration speed. Meanwhile the more various strategies of groupitizing in arrangements will cause slower enumeration speed, but regularity of arrangements does not guarantee the accuracy of responses.
