In the absence of such evidence, one might have expected a difference in the amount of transfer shown by the two hands. The significance of the interaction shown in Row 5 of Table 2 means that some Ss showed more transfer than others. This is of course, not surprising, and it was suggested strongly by inspection of the raw data. There was a significant interaction between S and hand as shown in Row 6. This finding is consistent with the experience of those who have observed the reading behavior of braille readers.
Some readers read much better with one hand than the other.
Others read equally well with either hand. Such individual differences are likely to be manifested in other cutaneous codes. Table 2 also shows the results of the analysis of variance of error scores. The entries, derived from error scores, support, in the main, the conclusions drawn from the analysis of variance of time scores, with one exception. The significant interaction between S and hand found when time scores were used was not found for error scores.
