Perceptual expertise in forensic facial image comparison.
Forensic facial identification examiners are required to match the identity of faces in images that vary substantially, owing to changes in viewing conditions and in a person's appearance. These identifications affect the course and outcome of criminal investigations and convictions. Despite calls for research on sources of human error in forensic examination, existing scientific knowledge of f...
متن کاملForensic handwriting examiners' expertise for signature comparison.
This paper reports on the performance of forensic document examiners (FDEs) in a signature comparison task that was designed to address the issue of expertise. The opinions of FDEs regarding 150 genuine and simulated questioned signatures were compared with a control group of non-examiners' opinions. On the question of expertise, results showed that FDEs were statistically better than the contr...
متن کاملLearning Image-Derived Eye Movement Patterns to Characterize Perceptual Expertise
Experts have remarkable capability of locating, identifying and categorizing objects in their domain-specific images. Eliciting experts’ visual strategies will benefit image understanding by transferring human domain knowledge into image-based computational procedures. In this paper, an experiment conducted to collect both eye movement and verbal description data from three groups of subjects w...
متن کاملModeling Perceptual Expertise
To have one’s hunches about how a simple combination of processes will behave repeated dashed by one’s own computer program is a humbling experience that no experimental psychologist should miss. Surprises are likely when the model has properties that are inherently difficult to understand, such as variability, parallelism, and nonlinearity—all, undoubtedly, properties of the brain. Hintzman, 1990
متن کاملTask-irrelevant perceptual expertise.
Perceptual learning (PL) and perceptual expertise (PE) are two fields of visual training studies that investigate how practice improves visual performance. However, previous research suggests that PL can be acquired in a task-irrelevant manner while PE cannot and that PL is highly specific to the training objects and conditions while PE generalizes. These differences are difficult to interpret ...
