Human Decision Making in Dynamic Real-World Environments

I am generally interested in human decision making in dynamic environments that approach real-world scenarios. Most recently, this involves determining deceptive processes in dynamic situations, and determining ways to deter deception in online interactions. I am also interested in certain aspects of decision making at the levels of the individual as perceiver, social or motivational influences on the individual, and the individual interacting with agents in dynamic environments.

• Feedback and Deception in Online Reputation Systems

  How and when do people decide for or against providing honest information when engaging in online marketplaces? What is the role of feedback, expectation, delay, and frustration in shaping deceptive practices online?

• Modelling Learning and Performance in Complex Scenarios with Hidden Features

  In real life, when humans try to control complex systems, there are many dynamic features at play. The tools or actions we use to try to control the system may be unreliable, there may be noise in the system which results in an unreliable feedback signal, there may be hidden mechanisms in the system which complicate the relationship between input and output. Using computational modelling, we can uncover behavioral patterns in how people attempt to control these systems, and how different forms of training can impact overall performance.

• Improving Workflow Efficiency using Applied Psychology

  Most tasks or jobs can be broken down into a series of subtasks. Prior work suggests that the order of these subtasks will make a difference in the performance and satisfaction factors of the person performing the overall task. Can generalized modeling predict which ordres would be most effective at maximizing performance? Asymmetries in subtask ordering are used to predict workflows which can maximize user performance and minimize completion time.

• Cognitive Consequences of Video Game Play

  In recent years, video games have developed into rich, dynamic, and fast-paced virtual environments. Prior work reveals that those who play video games demonstrate enhanced cognitive and perceptual performance in a range of tasks. This is true for both chronic video game players (VGP) and non-video game players (NVGP) who are trained on video games (Dye, Green, & Bavelier, 2009). 

  Most previous research uses a subtype of video games known as action video games. Action video games feature a first-person perspective, and the participant navigates a three-dimensional world (e.g., Unreal, Doom, see example here). The fast paced game play in action video games typically consists of engaging other agents in the virtual world (i.e., killing them with projectile weapons). Here, we are interested in an alternative subtype of video games known as real-time strategy games (RTS; e.g., StarCraft, Age of Empires, see example here). Game play in RTS games is from a third-person perspective with the participant constructing and controlling an army represented by several agents on a large map. The participant commands this army in battle against an enemy army. Despite many concurrent game situations unfolding in real-time, only a portion of the entire game world (i.e., game map) and a portion of the agents can be seen on the monitor at a given time. Participant must track and switch between many evolving states in order to be successful. We employ a variety of novel methods to capture which game features are associated with various cognitive enhancements. Thus, RTS games represent a unique research opportunity due to the possibility that attentional mechanisms could be altered and perhaps enhanced by RTS training. Additionally, the long term effects of RTS gaming is not known.

• Individual as Perceptual Classifier

  What is the role of feedback, intradimensional shifts and extradimensional shifts in category learning? Multiple systems have been implicated in human category learning, and model based analyses help to determine strategies that people may adopt in different types of tasks.

• Motivational and Regulatory Influences on Individual Performance

  What is the role of regulatory focus on set shifting tasks that require cognitive flexibility and signal detection tasks that require shifts in response bias and perceptual sensitivity? How does the stress of fatigue and sleep deprivation impact people in high performance situations?

• Individual Interacting with Agents

  1. By developing models that can drive simulated opponents, single participants perform resource acquisition tasks in controlled environments. These models are used in combination with a two-dimensional foraging task (see Goldstone and Ashpole 2005) to examine individual level behavior such as the tradeoff between exploration and exploitation.

  2. Humans can teach as well as learn from agents, and I am interested in psychological properties as well as properties of computer agents that drive learning in human-agent interactive scenarios.
