We present the case of a 61-year-old man who presented to his primary care provider for a routine visit and was found to have a pulsatile mass in his right neck. This case report shows the importance of a thorough physical exam during patient visits. In this case, the physical exam resulted in the diagnosis of a carotid body tumor (CBT) prior to the patient becoming symptomatic from it.

However, accuracy typically does not improve following an error, leading some researchers to suggest that an initial 'orienting' response may initially impair performance immediately following error.

Digital Frequency-domain Multiplexing (DfMux) is a multiplexing technique used in many CMB polarization experiments, such as the Simons Array, SPT-3 G, and EBEX. The DfMux system studied here uses LC filters with resonant frequencies ranging from 1.

Our goals sometimes conflict with our prepotent habitual responses, which often leads to impaired performance on a variety of tasks. People are better at exerting cognitive control to overcome prepotent and automatic responses when they are motivated by the prospect of reward. The standard experimental paradigms used to study this phenomenon examine free RTs that allow participants to select a variety of response strategies including delaying response initiation to avoid committing errors.

Studies have shown that prospective rewards improve performance on visual working memory tasks, but it remains unclear whether rewards increase total resource availability or simply influence the allocation of resources. Participants performed a continuous report visual working memory task with oriented grating stimuli.
