Distractors interfere with numerical estimation in Chinese college students as a function of field-dependent or field-independent cognitive style.

Field-dependent/independent groups' numerical estimation was assessed with respect to different distractors. Participants were 81 college students with field-dependent or field-independent cognitive styles. Cognitive style had a significant main effect on reaction without distractors. When the number of distractors was double the number of targets, the estimation accuracy of the field-dependent and field-independent groups differed. Under this double-distractors condition, both the field-dependent and field-independent participants used logarithmic representation more than linear representation in their numerical estimations, but no significant between-group differences were found.
