    "title": "How Different Frames of Reference Interact: A Neural Network Model",
    "subtitle": null,
    "abstract": "It has been argued that people use multiple frames of\nreference (FORs) for representing and updating spatial\nrelationships between objects in a complex environment.\nWhen there are conflicts among representations of multiple\nFORs, they compete to determine behavior. “Frame of\nReference-based Map of Salience” theory (FORMS) suggests\nthat FORs with high salience may be processed in priority.\nHere, we report a computational neural network model for a\ntwo-cannon task, which naturally involves multiple FORs\nwith different levels of salience: intrinsic frame of reference\n(IFOR) and egocentric frame of reference (EFOR). The goal\nis to investigate the computational neural mechanisms\nunderlying human spatial performance. Our simulation results\nfit earlier behavioral results well. The model suggests\nalthough multiple FORs may be initially represented\nindependently, they interfere with each other by the inhibitory\ncompetition of neurons in the later process (in hidden layer)\nfor conflict resolution. Moreover, salience may modulate the\ncompetition by prioritizing FORs with high salience levels.\nThese results represent a connectionist support for the\nFORMS theory.",
