We recorded the eye positions of 18 expert latent print examiners and 18 novice participants across two separate experiments that were designed to represent abbreviated latent print examinations. In the first experiment, participants completed self-paced latent and inked comparisons presented on a computer monitor while their eyes were tracked with a(More)
BACKGROUND Regression of intestinal metaplasia to cardiac mucosa in patients with Barrett's (BE) esophagus could alter the natural history of BE. OBJECTIVE To determine the regression of intestinal metaplasia to cardiac mucosa in patients followed more than 5 years after operation, by repeated endoscopy with biopsy. MATERIAL AND METHODS This prospective(More)
Latent print examinations involve a complex set of psychological and cognitive processes. This article summarizes existing work that has addressed how training and experience creates changes in latent print examiners. Experience appears to improve overall accuracy, increase visual working memory, and lead to configural processing of upright fingerprints.(More)
Our brains readily decode human movements, as shown by neural responses to face and body motion. N170 event-related potentials (ERPs) are earlier and larger to mouth opening movements relative to closing in both line-drawn and natural faces, and gaze aversions relative to direct gaze in natural faces (Puce and Perrett, 2003; Puce et al., 2000). Here we(More)
Gaze direction, a cue of both social and spatial attention, is known to modulate early neural responses to faces e.g. N170. However, findings in the literature have been inconsistent, likely reflecting differences in stimulus characteristics and task requirements. Here, we investigated the effect of task on neural responses to dynamic gaze changes: away and(More)
Our brains readily decode facial movements and changes in social attention, reflected in earlier and larger N170 event-related potentials (ERPs) to viewing gaze aversions vs. direct gaze in real faces (Puce et al., 2000). In contrast, gaze aversions in line-drawn faces do not produce these N170 differences (Rossi et al., 2014), suggesting that physical(More)
ExpertEyes is a low-cost, open-source package of hardware and software that is designed to provide portable high-definition eyetracking. The project involves several technological innovations, including portability, high-definition video recording, and multiplatform software support. It was designed for challenging recording environments, and all processing(More)
prints are often the only physical evidence left at a crime scene, but these are typically invisible until developed and lifted. Even after they are dusted with lifting powder and stabilized using clear lifting tape or fixed using cyanoacrylate fumes, friction ridge impressions may be corrupted by visual noise or may have missing regions. In some cases, it(More)
BACKGROUND Gastrointestinal stromal tumors (GIST) are the most common mesenchymatous tumors of the digestive tract. The pathological diagnosis is based on microscopy and immunohistochemistiy. AIM To review the experience of our surgical unit in patients with GIST MATERIAL AND METHODS: Review of medical records of 15 patients (aged 66+/-13 years, 11(More)
