Furthermore, few guidelines exist to aid the knowledge engineer in the difficult task of explicating the components of expert reasoning. Errors in knowledge acquisition may yield representational inadequacies which undermine the integrity of the knowledge base and, consequently, performance of the system. We propose that insight into the important issues surrounding knowledge acquisition can be gained by acknowledging the fundamental malleability of the cognitive mechanism. In this paper we describe a heuristic framework for understanding and investigating factors influencing cognitive malleability and, consequently, knowledge acquisition efforts. We illustrate how this framework can be applied in the context of engineering problem solving and discuss how an appreciation for these factors can help avoid errors in knowledge acquisition and assist in acquisition efforts.

However, the evidence on specific associations is still inconclusive. A previous study conducted at a Sterile Processing Department (SPD) in a local hospital established an association between perceived job demands and adverse body postures. However, causal inferences were not possible to establish given the study design. Consequently, the objective of this study was to determine if perception of mental workload causes workers to use more risky body postures. Objective and subjective assessment tools (REBA and NASA-TLX scores) were used as indicators of body postures and mental workload. The findings indicated that there is a positive relationship between the perception of workload (NASA-TLX scores) and adverse body postures (REBA scores) suggesting that people tend to adopt more awkward postures when they feel they are in...

Current progress of three advanced prototype instrument development projects looking at non-contact sensing of human physiology to determine the veracity of human communications are presented. These include: 1) Thermal Facial Screening (TFS); 2) Turnkey Remote Assessment of Concealed Knowledge using Eye movement Recordings (TRACKER); and 3) Laser Doppler Vibrometry (LDV). Signals are measured with superior technical quality, in comparison to those obtained with conventional contact methods. Depending on the operational need and the specific context, these instruments can be used as stand-alone techniques or integrated into a multi-modal evaluation of human credibility. Thus, a comprehensive assessment using multiple physiological response systems is possible. A description each technique, the current state of these research efforts, and an overview of the potential for each of these emerging technologies will be provided.

New technologies may offer assistance to law enforcement personnel in the interview and interrogation process. Additionally, homeland defense against terrorism challenges scientists to develop new methods of assessing truthfulness
