Training performance-influencing factors

All critical errors and recovery points for task steps are recorded in accordance with the conventions of the PHEA and provide a valuable input to the specification of warnings and cautions for the design of procedures. In addition, various performance-influencing factors which contribute to the occurrence of critical errors can be identified which can provide input to the development of other error reduction measures such as training, and control panel design. 

The use of feedback is another factor that influences team motivation and performance. Feedback helps to motivate an individual concerning recently performed tasks (Sedas et al. 1992). Researchers concur that the feedback should be given within a short period of time eifter the relevant performance (Dyer 1984 Nieva et al. 1978). The sequence and presentation of the feedback may also play significant roles in motivation. Salas et al. (1992) have noted that during the early stages of training.

The level of amputation is selected based on the potential for healing and future function. Vascular surgeons, who may or may not have special training in prosthetic rehabilitation, perform most amputations. Orthopedic surgeons, who complete a course in prosthetics as part of their residency, perform amputations necessitated by trauma, malignancy, and other nonvascular causes. Factors influencing the level of vascular amputation include the local blood supply, the nutritional state of the patient, and the probability of successful fitting. Level selection for traumatic amputations or major tumors is based on the nature of the injury and the viability of the remnant tissues. 

The human error probabilities used should reflect the factors which can influence the performance of the operator, including the level of stress, the time available to carry out the task, the availabihty of operating procedures, the level of training and environmental conditions. These should be identified by the task analysis carried out as part of the design evaluation. 

These are the conditions in existence immediately prior or at the time of the incident that directly influences human and equipment performance in the workplace. These are the circumstances under which the errors and violations took place and can be embedded in task demands, the work environment, individual capabilities and human factors. Deficiencies in these conditions can promote the occurrence of errors and violations. They may also stem from an organizational factor type such as risk management, training, incompatible goals, or organization, when the system tolerates their long term existence.
