Effects of cognitive workload on body behavior

biomech project

Looking for participants

The purpose of this study is to determine if increases in perceived mental workload create higher levels of physical risk.

An understanding of the interaction between physical (postural risk) and perception of mental workload will lead to several practical implications in workload planning, staff scheduling, process selection, workstation, task design, training plans, among others which will create a significant positive impact on workers’ health and therefore on public health. 

You will be asked to perform an activity that emulates the insertion of a nasogastric tube on a maniquin.

We will tape small reflective markers to certain points on skin and clothing over your arms and torso. Special cameras will track the motion of these markers. There may be some minor discomfort when the double-sided tape is removed from skin, like pulling off a small bandage.

We will also collect saliva samples before, during and after the experiment. These samples will be used to estimate cortisol levels as a measure of stress. 

Cameras in the facility will videotape you. We will use the videotapes to conduct ergonomic analysis. The videos are going to be recorded in a manner that is not possible to identify directly or through identifiers linked to you.

You will fill out three questionnaires, the NASA-TLX, the SURG-TLX, and VAS which are multidimensional scale questionnaires designed to obtain information about the workload experienced when you perform the activities. You also will fill out the big five personality traits questionnaire that will give us information about your personality type.

The total time of the experiment will be approximately 1.5 – 2 hours.

Participants will receive a $20 gift card for their participation.
