Figure 4.

Results of two experiments by Jaśkowski and Ślósarek (2007) with primes of different shapes. Priming effect [= RT(incompatible) – RT(compatible)] is plotted as a function of the prime-target interval. The shapes of the primes used are shown near each plot. In the experiment whose results are presented in the left graph, the masks were formed from lines of different orientation and length, randomly dispersed over an area. The mask used in the other experiment was formed from the two primes of a given pair overlaid with one another. Note that overlaying the two pairs of the primes forms the identical mask.
