The Influence Of Facial Exposure On Confidence In Eyewitness Identification, Madelynn Fancher
The Influence Of Facial Exposure On Confidence In Eyewitness Identification, Madelynn Fancher
Psychological Science Undergraduate Honors Theses
In crimes in which there is an eyewitness identification, confidence is usually a good predictor of accuracy. However, in some cases, estimator variables might affect the relationship between eyewitness confidence and accuracy. This study analyzes the effect of exposure duration on confidence during an eyewitness identification. According to the pristine conditions hypothesis (Wixed & Wells, 2017), if the system variables are optimal, confidence and accuracy will be strongly related, even if the viewing conditions are suboptimal. Participants in this online study viewed a mock crime in one of two conditions: brief exposure or long exposure. Following viewing the crime, participants …

Like Me, Do What I Say, & Think About My Influence: The Effects On Witness Choosing And Metacognition, Brittany Race
Graduate Theses and Dissertations
Confidence can be a strong predictor of accuracy if circumstances are ideal (Wixted & Wells, 2017), but ideal circumstances are not always present. As such it is important to understand ways to ameliorate potentially negative effects on eyewitness metacognition. Rapport building, though seen as an important element of police/witness interaction (Vallano et al., 2015), can lead to some potentially negative memory effects (Wright et al., 2015). Additionally steering, or the process of directing a witness toward a particular suspect, can increase false identifications. Recently the researcher has developed a paradigm meant to better calibrate confidence by reinstating the context of …
Fitting Eyewitness Identification And Confidence To A Diffusion Model Of Processing, Brittany Nicole Race
Fitting Eyewitness Identification And Confidence To A Diffusion Model Of Processing, Brittany Nicole Race
Graduate Theses and Dissertations
It is necessary to better serve justice to understand the mechanisms behind eyewitness identification and reports of confidence. The material contained within attempt to fit eyewitness identification to a diffusion model of processing, RTCON (Ratcliff & Starns, 2009). Participants saw eight mock crime videos and were then tasked with using eight showups or eight lineups to identify the suspects within the video. Half of the presentations were target present and half were target absent. Additionally, participants were either presented with biased or unbiased instructions. Strangely, unbiased lineups led to higher hit rates which is contrary to most findings in the …
