When making inferences about another person (the target), perceivers often have to integrate multiple sources of informa-tion. This can include stereotypes about the targets groups (e.g., age, race, occupation) as well as other information aboutthe target (individuating information). In simple situations, perceivers approximate ideal Bayesian information integra-tion, relying more heavily on information that is more informative for the judgement. However under cognitive load withcognitive resources taken up by other demands people may instead rely on simplifying heuristics. We investigate severalpossible heuristics that people may use under load, including relying primarily on stereotypes rather than individuatinginformation, as suggested by previous research, and we test if and how these heuristics depend on how informative eachsource of information is. By clarifying how stereotypes are used in less-than-ideal cognitive conditions, this work hasimplications for when stereotypes will tend to be overused in real-world situations.

BACKGROUND: Prepancreatic postduodenal portal vein is extremely rare, with only 13 cases reported in the literature. CASE PRESENTATION: A 55-year-old white woman presented to our emergency department with abdominal pain. She underwent a computed tomography of her abdomen, which showed a portal vein coursing anterolaterally to her pancreas and posteriorly to the first portion of her duodenum, constituting a prepancreatic postduodenal portal vein. Imaging revealed choledocholithiasis, requiring endoscopic sphincterotomy, but due to a history of a gastric bypass procedure, she was lost to follow-up after being referred to an advanced endoscopist. This represents the 14th reported case of prepancreatic postduodenal portal vein. CONCLUSIONS: Awareness of this rare anomaly is paramount, and will help surgeons and interventional radiologists to avoid complications related to inadvertent injury to the portal vein, which could be life-threatening.
