A Descriptive Analysis Of The Appropriate Use Of Cognitive Bias Terminology In Forensic Science Literature, Courtney A. Winters, Evelyn M. Buday, Trevor I. Stamper Aug 2015

A Descriptive Analysis Of The Appropriate Use Of Cognitive Bias Terminology In Forensic Science Literature, Courtney A. Winters, Evelyn M. Buday, Trevor I. Stamper

The Summer Undergraduate Research Fellowship (SURF) Symposium

Cognitive bias occurs without a person’s awareness and can affect decision-making abilities. In forensic science, bias can be especially detrimental to making accurate decisions about the evidence in a criminal investigation. There are many academic studies in identifying, describing, and suggesting ways to mitigate cognitive biases in forensic science. Many authors will give a known cognitive science concept a new name or create their own bias. This is a problem in the literature because nobody knows for sure how many published studies are referring to or testing the same phenomena since authors are using different definitions or terminology to describe …

A Signal Detection Experiment With Limited Number Of Trials, Tadamasa Sawada May 2015

A Signal Detection Experiment With Limited Number Of Trials, Tadamasa Sawada

MODVIS Workshop

Signal detection theory has been well accepted in vision science to measure human sensitivity to stimuli in a Psychophysical experiment. The theory is formulated so that the measured sensitivity is independent from a response bias (criterion). The formulation is based on an assumption that number of trials in the experiment is infinite but this assumption cannot be satisfied in practice. The assumption came from two normal distributions used in the formulation. The distributions respectively represent a set of signal trial and that of noise trials in the experiment. In this study, I will show how the violation of the assumption …


Bayesian Modeling Of 3d Shape Inference From Line Drawings, Seha Kim, Jacob Feldman, Manish Singh May 2015

Bayesian Modeling Of 3d Shape Inference From Line Drawings, Seha Kim, Jacob Feldman, Manish Singh

MODVIS Workshop

Human depth comparisons in line drawings reflect the underlying uncertainty of perceived 3D shape. We propose a Bayesian model that estimates the 3D shape from line drawings based on the local and non-local contour cues. This model estimates the posterior distribution over depth differences at two points on a line drawing. The likelihood is numerically computed by assuming a generative model, which generates random 3D surfaces and, via projection, random line drawings. The 3D surfaces are inflated from random skeletons and projected into line drawings. Given a novel line drawing, the model samples probable local surfaces based on the relations …


Password Strength Analysis: User Coping Mechanisms In Password Selection, Brian Thomas Curnett Apr 2015

Password Strength Analysis: User Coping Mechanisms In Password Selection, Brian Thomas Curnett

Open Access Theses

The security that passwords provide could be seriously flawed due to the way people cope with having to memorize and recall their passwords. The National Institute of Standards and Technology (NIST) standard that is used to measure the password strength, known as entropy, is designed for a single use and does not consider that users may choose to keep parts of their password across password changes. This study shows that a portion of users keep some information from previous passwords across changes. These habits which will be called coping mechanisms that over time serve to erode the protection provided by …


Seeing People, Seeing Things: Individual Differences In Selective Attention, Miranda May Mcintyre Apr 2015

Seeing People, Seeing Things: Individual Differences In Selective Attention, Miranda May Mcintyre

Open Access Theses

Individuals differ in the extent to which they attend to their physical and social environments, but little empirical work has measured these differences at a cognitive level. To address this gap, two studies explored the association between attentional processes and Person and Thing Orientations. The first study measured visual selective attention toward person- and thing-related image components. In the second study, participants provided written responses about a set of images; linguistic analyses were conducted to assess attentional bias toward interest-congruent content. The results from both studies support motivated attention as a process through which interests in physical and social environments …
