Notes

The tests were described by an outer array of 32 symbol-digit arrays each containing the digits 0-7. To present some element of unpredictability between participants, each run of the program chose a random starting point in the outer array and presented tests from that point onwards (looping back to the origin if required). The outer array was zero-indexed, so that a value of 0 in this field means that the first symbol-digit array was used for the Coding array.

To illustrate, suppose a participant was allocated the value 5 for their start array. Then round 1 would use Array 4 [values 4,5,1,3,7,2,6,0] for the Code and Array 5 [3,5,2,0,4,6,1,7] for the Test. Round 2 would still use Array 4 for the Code but Array 6 [6,3,7,2,4,5,0,1] for the test etc.

The test arrays are listed below, and also in Data-Coding 500 with the symbol dictionary shown in Resource 111.

28) 0,6,7,5,1,2,3,4
29) 4,3,1,0,6,5,2,7
30) 5,4,6,7,1,0,2,3
31) 0,4,7,2,3,1,5,6

The first round (attempts 0-7) used a constant fixed pattern [2,4,6,1,3,5,7,0] for the Code Array and [7,1,5,4,6,0,3,2] for the test Array for all participants.
