    • Evaluating the effects of image persistence on dynamic target acquisition in low frame rate virtual environments 

      Appelbaum, Lawrence Gregory; Kopper, Regis; Potter, Nicholas; Rao, Hrishikesh; Sommer, Marc A; Zielinski, David (IEEE 3D User Interfaces (3DUI), 2016-03-19)
      User performance in virtual environments with degraded visual conditions due to low frame rates is an interesting area of inquiry. Visual content shown in a low frame rate simulation has the quality of the original image, ...
    • Probabilistic inference under time pressure leads to a cortical-to-subcortical shift in decision evidence integration 

      Beck, JM; Egner, Tobias; Ferrari, Silvia; Oh-Descher, H; Sommer, Marc A (NeuroImage, 2017-08-24)
      Real-life decision-making often involves combining multiple probabilistic sources of information under finite time and cognitive resources. To mitigate these pressures, people “satisfice”, foregoing a full evaluation of ...
    • Satisficing in split-second decision making is characterized by strategic cue discounting 

      Beck, JM; Egner, Tobias; Ferrari, Silvia; Oh, H; Sommer, Marc A; Zhu, Pingping (Journal of Experimental Psychology: Learning, Memory, and Cognition, 2016-03-11)
      Much of our real-life decision making is bounded by uncertain information, limitations in cognitive resources, and a lack of time to allocate to the decision process. It is thought that humans overcome these limitations ...
    • Sensorimotor learning during a marksmanship task in immersive virtual reality 

      Appelbaum, Lawrence Gregory; Clements, Jillian; Khanna, Rajan; Kopper, Regis; Lu, Y; Potter, Nicholas; Rao, Hrishikesh; ... (9 authors) (Frontiers in Psychology, 2018-01-15)
      Sensorimotor learning refers to improvements that occur through practice in the performance of sensory-guided motor behaviors. Leveraging novel technical capabilities of an immersive virtual environment, we probed the component ...
    • Serial decision-making in monkeys during an oculomotor task 

      Abzug, Zachary Mitchell; Sommer, Marc A (Journal of Experimental Psychology: Animal Learning and Cognition, 2017-08-29)
      Much of everyday behavior involves serial decision-making, in which the outcome of one choice affects another. An example is setting rules for oneself: choosing a behavioral rule guides appropriate choices in the future. ...

    • Supplementary Eye Fields 

      Abzug, Zachary Mitchell; Sommer, Marc A (Reference Module in Neuroscience and Biobehavioral Psychology, 2017)
      The supplementary eye fields (SEFs) are located in dorsomedial frontal cortex and contribute to high-level control of eye movements. Recordings in the SEF reveal neural activity related to vision, saccades, and fixations, ...
