We
examined the perceptual and cognitive characteristics of the playing cards
commonly used in the Western world. Specifically, we measured their visibility,
memorability, likability, and verbal and visual accessibility. Based on
visibility and memorability, four groups of cards were distinguished: the Ace
of Spades, other Aces, number cards, and face cards. Within each of these groups,
there were few differences due to value or suit. Based on likability and
accessibility, three additional groups were distinguished: the Ace of Hearts,
Queen of Hearts, and King of Hearts.
Several interesting relations were found between how people remember,
like, and access cards; some of these were similar to effects found in studies
of visual perception, while others seemed entirely new. Our results demonstrate
that rigorous examination of real-world stimuli can shed light on the
perception of ordinary objects, as well as help us understand why magic works
in the mind.
