We present a computational model capable of predicting-above human accuracy-the degree of trust a person has toward their novel partner by observing the trust-related nonverbal cues expressed in their social interaction. We summarize our prior work, in which we identify nonverbal cues that signal untrustworthy behavior and also demonstrate the human mind's(More)
Heartbeat detection tasks are often used to measure cardiac interoceptive sensitivity-the ability to detect sensations from one's heart. However, there is little work to guide decisions on the optimum number of trials to use, which should balance reliability and power against task duration and participant burden. Here, 174 participants completed 100 trials(More)
We examined how the Boston Marathon bombings affected threat perception in the Boston community. In a threat perception task, participants attempted to "shoot" armed targets and avoid shooting unarmed targets. Participants viewing images of the bombings accompanied by affectively negative music and text (e.g., "Terror Strikes Boston") made more false alarms(More)
Behavior is comprised of decisions made from moment to moment (i.e., to respond one way or another). Often, the decision maker cannot be certain of the value to be accrued from the decision (i.e., the outcome value). Decisions made under outcome value uncertainty form the basis of the economic framework of decision making. Behavior is also based on(More)
CONTEXT Early studies suggested that experienced clinicians simply generate more accurate diagnoses than those less experienced. However, more recent studies indicate that experienced clinicians may be subject to biases in formulating and confirming hypotheses that lead to inaccuracy. OBJECTIVES The goal of this study was to identify factors associated(More)
Three studies examine the impact of an anger manipulation on threat perception among Northeastern University students after the Boston Marathon bombings. Data collection for one experiment began within 24 hours of the bombings. Results suggest that the impact of anger on threat perception differed during the week of the bombings compared to 1 and 5 months(More)
OBJECTIVE Electrodermal activity (EDA) is a non-invasive measure of sympathetic activation often used to study emotions, decision-making, and health. The use of "ambulatory" EDA in everyday life presents novel challenges-frequent artifacts and long recordings-with inconsistent methods available for efficiently and accurately assessing data quality. We(More)
