Procedure:
Each participant was proctored to individually. Two cards making up the pair were placed in front of the participant face on the table. For the listing task the experimenter provided an example of a list using a single test image. Using a piece of paper the participant was then asked to list five attributes of each scene in separate columns.

For the mapping task the experimenter pointed to the predetermined object for mapping and asked the participant to point to its correspondent in the other image. This process was repeated so that each participant made two matches for each pair of images. Mapping responses were recorded by the experimenter.
