Abstract

Conducted 4 experiments with 1 exceptional S. The S guessed playing cards taken one at a time from a large pool and then enclosed in a black folder. Data were analyzed with an adaptation of R. A. Fisher's method (1924) for each series and for the pooled data. Significant results were obtained in all 4 experiments and with the pooled data. The number of exact hits was 3 times chance expectations, giving a color and rank (CR) score of 13. The number of exact hits was also much larger than would be expected on the basis of chance association of the independently significant tendencies to hit numbers (CR > 7) and to miss suits (CR < -3). The chi square for association between the number of hits and the number of suit hits corresponded to a CR of 5.8, showing that the S guessed the whole target if he guessed either of its component attributes.
