First, do confidence scales ranging from 4 and 5 points to 20 and 100 points produce different confidence-accuracy relationships?
The present experiments addressed three primary questions: First, do different ranges of confidence scales yield similar confidence-accuracy relationships?
The aim of the present experiments was to examine a neglected factor in considering confidence-accuracy relationships: the range of the confidence scale.
Despite the array of findings in the literature, the field is making good progress in understanding confidence-accuracy relationships in memory.
Most experiments on confidence-accuracy relationships use some form of recognition test, although, of course, analyses can be applied to recall, as in Dallenbach's study (1913), in which he used cued recall.
Brewer, N. & Wells, G. L. The confidence-accuracy relationship in eyewitness identification: effects of lineup instructions, foil similarity, and target-absent base rates.
Taken together, these findings may suggest that impairments in the confidence-accuracy relationship for memory in older adults, which are often driven by high-confidence errors, may be primarily related to altered neural signals associated with greater activity for high-confidence responses.
This defines the decision speed-accuracy relationship that characterizes mammography expertise.
Hence, the confidence-accuracy relationship for hits is indeed steeper than that for correct rejections.
They showed that the confidence-accuracy relationship was generally the same with all types of scales.
This might be one reason for the differences observed in the confidence-accuracy relationship between list-learning and eyewitness situations.
