“…This has been interpreted as meaning that judgments of confidence were not influenced by the precision of memories but were based on how sure the participant was that the location he or she was recalling was that of the object he or she was being asked to recall. This inability to use precision information in judgments of confidence has been observed in other studies (Lansdale & Cotes, 1999). Why participants were unable to use (or did not have available) precision information represents an interesting puzzle for future research.…”

The authors investigated whether memory for object locations in pictures could be exploited to address known difficulties of designing query languages for picture databases. M. W. Lansdale's (1998) model of location memory was adapted to 4 experiments observing memory for everyday pictures. These experiments showed that location memory is quantified by 2 parameters: a probability that memory is available and a measure of its precision. Availability is determined by controlled attentional processes, whereas precision is mostly governed by picture composition beyond the viewer's control. Additionally, participants' confidence judgments were good predictors of availability but were insensitive to precision. This research suggests that databases using location memory are feasible. The implications of these findings for database design and for further research and development are discussed.

A model for recall of location is presented that postulates 2 encoding processes: 1 producing exact (all-or-none) recall, the other resulting in inexact recall. Exact recall is modeled as the outcome of a perceptual discrimination process, and inexact recall is modeled as the incomplete outcome of a Poisson process of information gain. The model accurately predicts levels of recall and patterns of errors in a number of experiments and articulates a lawful relationship between recall and elements of picture composition, such as the dimensions of the to-be-recalled attributes and the configuration of anchor points in the picture. This model enables a reappraisal of previous theoretical approaches to memory for location and of related studies concerned with automaticity in memory. The significance of this model as a general analytical device for the study of continuous attributes in memory is discussed.
