Materials and Design
Altogether 96 noncolor-specific objects were used.
Forty-eight of them stemmed from the second experiment,
the other 48 were newly selected from the
Corel Draw Clipart set. They were all line drawings
filled with one of the four colors, like in Experiment
2, so that silhouettes resulted. From these items, two
sets of four study lists were composed with 48 items
each. Across the 4 lists, the colors of items were
counterbalanced within a set. Apart from that, there
was a test list comprising all 96 items, so that half
of the items were old and the other half new, respectively.
The whole variation therefore occurred within
subjects. The assignment of items to conditions was
counterbalanced.
