Experimental evaluation of retroreflective markings on trains and grade crossings
… Receiver Operating Characteristic (ROC) based on Signal Detection Theory (SDT). The second experiment involved a driving task in which the subject encountered numerous grade crossings, and the recognition distance between the train and subject's position was recorded and analyzed.

The Effects of Sensor Performance as Modeled by Signal Detection Theory on the Performance of Reinforcement Learning in a Target Acquisition Task
… of sensor performance, as modeled through Signal Detection Theory (SDT), on the ability of RL algorithms to accomplish a target localization task are examined. Three levels of sensor sensitivity are simulated and compared to the results of the same system using a perfect sensor. To …

Working Memory, Search, And Signal Detection: Implications For Interactive Voice Response System Menu Design
… determine whether theories of visual search and signal detection theory (SDT) could be used to predict auditory search behavior. Results of this experiment indicate that creating a deeper structure with shorter menus is detrimental to performance and satisfaction and more demanding of working …

Integration of Multidimensional Signal Detection Theory with Fuzzy Signal Detection Theory
Signal detection theory (SDT) has proven to be a robust and useful statistical model for analyzing human performance in detection and decision making tasks. As with many models extensions have been proposed in order capture and represent the real world to a greater degree. Multidimensional Signal …

Relational Red Flags: Detecting Undesirable Qualities in Initial Romantic Encounters
<p>This dissertation extends the work of Signal Detection Theory (SDT) (Green & Swets, 1966; Swets, 1964) in the social sciences by applying it to romantic relationships, specifically initial romantic encounters (i.e. formal or informal first few dates, or random, chance encounters). The term …

An Empirical Exploration of Countermeasures in HCI-Based Deception Research
… countermeasures that is present in the deception detection literature to date was mapped out by conducting a literature review of countermeasures related work in the deception detection discipline. Second, after evaluating and analyzing this literature, Signal Detection Theory (SDT) was leveraged …

Debiasing reasoning : a signal detection analysis
… a particular answer, independent of reasoning. A Signal Detection Theory (SDT) approach is used to calculate measures of reasoning accuracy and response bias. These measures are then analysed using mixed effects models. Chapter 1 gives a general introduction to the topic, and outlines the content …

Rater Drift in Constructed Response Scoring via Latent Class Signal Detection Theory and Item Response Theory
… using two measurement models - latent class signal detection theory (SDT) and item response theory (IRT) models. Rater effects (e.g., leniency and strictness) are partly examined with simulations, where the ability of different models to capture changes in rater behavior is studied. Drift is …

Detecting Threats from Constituent Parts: A Fuzzy Signal Detection Theory Analysis of Individual Differences
Signal detection theory (SDT) provides a theoretical framework for describing performance on decision making tasks, and fuzzy signal detection theory (FSDT) extends this description to include tasks in which there are levels of uncertainty regarding the categorization of stimulus events. …

Understanding the Time Course of Bias in Simple Memorial Decisions
… in the context of traditional metrics including Signal Detection Theory (SDT) and The Diffusion Model (DM). I propose an alternate analysis framework utilizing the response time predictions made by the DM and provide converging evidence from an underutilized metric, delta plots, which provide …

Role of Mouse Visual Cortex in Perception of Stimulus Features
… task. Instead, suppressing PM increases contrast detection threshold and consistently increases false alarm rate in both contrast and speed increment detection tasks. The effects of PM suppression on false alarm rate remain intact even when the visual stimuli are presented outside of the affected …

An Archival Analysis of Stall Warning System Effectiveness During Airborne Icing Encounters
… icing. The model combined Bayes’ Theorem with Signal Detection Theory (SDT) concepts to yield testable predictions that were evaluated using a Binary Logistic Regression (BLR) multivariate technique applied to two archives: the NASA Aviation Safety Reporting System (ASRS) incident database, and …

The role of noise in brain dynamics processes
… defined as a random fluctuation of the measured signal, is usually considered to be detrimental. Thus, many techniques have been developed to reduce its impact: for example, the most common post–processing procedure to improve a noisy measurement consists in averaging the measured signal over …
