Recent research using a calibration approach indicates that eyewitness confidence assessments obtained immediately after a positive identification decision provide a useful guide as to the likely accuracy of the identification. This study extended research on the boundary conditions of the confidence-accuracy (CA) relationship by varying the retention(More)
Trying to remember something now typically improves your ability to remember it later. However, after watching a video of a simulated bank robbery, participants who verbally described the robber were 25% worse at identifying the robber in a lineup than were participants who instead listed U.S. states and capitals-this has been termed the "verbal(More)
Eyewitness identification decisions are vulnerable to various influences on witnesses' decision criteria that contribute to false identifications of innocent suspects and failures to choose perpetrators. An alternative procedure using confidence estimates to assess the degree of match between novel and previously viewed faces was investigated.(More)
The potential influence of video game violence on real-world aggression has generated considerable public and scientific interest. Some previous research suggests that playing violent video games can increase postgame aggression. The generalized aggression model (GAM) attributes this to the generalized activation of aggressive schemata. However, it is(More)
Choices from arrays are often characterized by position effects, such as edge-aversion. We investigated position effects when participants attempted to pick a suspect from an array similar to a police photo lineup. A reanalysis of data from 2 large-scale field studies showed that choices made under realistic conditions-closely matching eyewitness(More)
Closed Circuit Television (CCTV) operators are responsible for maintaining security in various applied settings. However, research has largely ignored human factors that may contribute to CCTV operator error. One important source of error is inattentional blindness--the failure to detect unexpected but clearly visible stimuli when attending to a scene. We(More)
Eyewitnesses regulate the level of detail (grain size) reported to balance competing demands for informativeness and accuracy. However, research to date has predominantly examined metacognitive monitoring for semantic memory tasks, and used relatively artificial phased reporting procedures. Further, although the established role of confidence in this(More)

A questionnaire was sent to all surgical registrars in Berlin and Brandenburg. The number of operations and other characteristic facts in surgical training were requested; 127 answers were sent back. The number of operations on colon, small intestine, stomach, and breast was not adequate to the required number of operations for specialist qualification in(More)
This research examined the influence of peripheral message cues on clinicians' judgment about the psychological status of clients. The elaboration likelihood model (ELM) of social persuasion suggests that peripheral message cues are likely to exert a greater influence on clinicians' judgments when a client's presentation meets some, but not all, diagnostic(More)
