Abstract

Continued the authors' experiments, requiring the S to shuffle a deck of playing cards to match a target deck shuffled earlier by the E. There were a total of 55 runs. The data gave significant results in all the series individually, as well as in the pooled data. The main effect was a massive excess of exact hits, about 4 times mean chance expectations. The presence of such excess exact hits, together with essentially chance performance on number and suit hits, suggests that the S produced many more exact hits than could be anticipated through chance association of his hits on the component attributes. The pattern of visual -like errors associated with the previous single-card clairvoyance experiment was not present.
