Perceptual-motor distortions, stress, and mental workload in the laparoscopic training environment
Laparoscopic surgery, a minimally invasive surgical approach, requires surgeons to view the target tissue on a monitor via a camera (i.e., laparoscope) that is partially inserted into the patient. Surgeons manipulate the target tissue using long, thin instruments that are also partially inserted into the patient. The laparoscopic environment poses perceptual-motor distortions for surgeons, including a disruption of the hand-eye mapping that occurs when the camera is located to the surgeon's side to obtain a better view of the target tissue. The aims of this line of research are threefold:
Determine whether basic perceptual-motor distortion theories generalize to novices in the laparoscopic training environment.
As the experience of mental workload and mental stress might interfere with skill acquisition and performance, my research team assesses the mental workload (attentional load) and mental stress experienced by novices in the laparoscopic environment.
Third, the long-term goal of this research is to develop laparoscopic training programs/modules.
Nature exposure and its impact on attention restoration
Prior research has indicated that nature interventions are effective for restoring our cognitive (attentional) resources (see Kaplan, 1995). Such interventions are not limited to actual nature immersions, but are also effective when utilizing digital nature pictures. However, certain other image characteristic might result in more effective interventions. Thus, the goals of this line of research are:
Determine image characteristics that result in more effective digital nature interventions.
Identify the limitations of digital nature interventions. For example, individual differences like anxiety, ADD/ADHD and depressive symptomatology may interfere with attention restoration.
