r: correlation coefficient; correlation is significant at the 0.01 level (2-tailed). Correlation is significant at the 0.05 level (2-tailed). ms: milliseconds; accuracy/correct (%) ranges from 0 to 100%. Span length is a discrete value (ranging from 1 to 9): the longest sequence participant correctly recalled. SOC parameters are all discrete. Mean move for 2, 3, or 4 is the average number of moves a participant takes to solve a problem that requires only 2, 3, or 4 moves, respectively. SOC: problems solved in minimum moves out of maximum possible 12.
