Data summary

Summary of detection statistics. d' is a measure of sensitivity. The larger the d' value, the better your performance. A d' value of zero means that you cannot distinguish trials with the target from trials without the target. A d' of 4.6 indicates a nearly perfect ability to distinguish between trials that included the target and trials that did not include the target. C is a measure of response bias. A value greater than 0 indicates a conservative bias (a tendency to say `absent' more than `present') and a value less than 0 indicates a liberal bias. Values close to 0 indicate neutral bias.
