The authors present an empirical investigation and a system dynamics model of human decision priming. Decision priming occurs when initial information creates the expectation that a given decision is appropriate, which speeds up or slows down decision making. A conjunction benefits-and-costs paradigm was used to collect the empirical data, whereas system dynamics techniques were used to create a computational model of decision priming. Decision priming occurred with simulated naturalistic stimuli (i.e., models of military tanks in a desert scene presented in perspective view), the results of which were modeled in a parallel-channels coactive architecture. Simulation revealed that the basic features of decision priming in humans could be simulated with this architecture. Decision priming likely occurs in naturalistic settings. Predictions derived from the model could provide useful information for the design of multimodal or multichannel displays.
Motivation-Validate a System Dynamics model of decision speed for a scenario relevant to an Air Force mission task. Research approach-Extend a decision priming basic research paradigm to a more applied case. Findings/Design-Decision priming was found to occur with more complex stimuli relevant to an air-to-ground target identification scenario. A system dynamics model was developed to predict those results. Research limitations/Implications-While decision delays of approximately 100 milliseconds were found here, it remains to be determined whether decision priming extends to decision processes extending over seconds or minutes. Originality/Value-A temporally-based method of modeling a decision process has been validated for an applied air-to-ground target identification scenario. Many other decision models lack this time component and are therefore of limited use in time-critical situations. Take away message-Tactical situations where information is processed rapidly and sequentially can result in decision priming.
Maintaining training proficiency during long combat deployments has become an important issue in recent years, and therefore the requirement for deployable training devices has also increased in importance. These training systems must not only deliver high fidelity, but must meet stringent requirements for reduced size for transportability and ease of set-up and operation. We describe an experiment examining the effect of reduced field of view on the control of a roll disturbance. Results indicated that, for control of roll angle, there was little change in performance for fields of view greater than 40 degrees. This finding provides evidence that field of view may be reduced in deployable systems without adversely affecting training effectiveness, at least for some essential capabilities.
Selective attention increased the proportion of time that the attended members of a pair of either simple (gratings) or more complex (movie clips) dichoptic stimuli were visible during binocular rivalry. Lower‐level stimulus attributes appear to be more important than meaningfulness in directing attention, which is a finding that may have relevance to the design of head‐worn displays.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
