But, there were statistically significant group differences in false alarm rates.
In a few other trials the subjects reported an error but did not make one (false alarm).
Normally sighted participants did not make any false alarm in these conditions.
Here, both groups appeared more likely to false alarm to semantically related pairs when the degree of semantic similarity was relatively high.
Second, problems that cannot be processed automatically can be handled here, thus reducing the false alarm rate of the grammar checker.
Overall the false alarm rate was very low-averaging about 1%.
Without taking into account false alarm rates, there were no group differences in recognition.
A hit response was a correct "word" response and a false alarm was an incorrect "word" response.
