Abstract
The involvement of low-level visual processes in the global precedence effect was investigated by selectively manipulating the low and high spatial frequency contribution by uniform field flicker masking and blurring, respectively. Uniform field flicker increased reaction times for the global stimuli and decreased reaction times for local stimuli. Blurring had little effect on reaction times for global stimuli but increased reaction times for local stimuli. The results support the proposal that the global precedence effect is partially a result of low-level visual mechanisms.
