Boredom factors

Table 3. Driver boredom factors mean scores and s.d.s for both sexes in the four factors and t-tests.

A number of issues emerge from this study in relation to driver boredom factors, risk and preferred speeds in this discussion the factors relating to driver boredom will be discussed first and followed by issues relating to the sex and age differences before relating these to preferred speeds on different road types. 

Several nontechnical factors can significantly affect the results of a nondestmctive inspection. Many of these are classified as human factors (1,2,17). Operator experience affects the probabiUty of detection of most flaws. Typically, an inexperienced operator has more false rejects, known as Type II errors, than an experienced operator. A poor operator has few false rejects but is more likely to miss a defect in the inspection, known as a Type I error. Operator fatigue, boredom, or an unfavorable environment such as lighting, cold, or rain may further affect performance. Thus it usually is a good investment for the inspection company to assure that the operator environment is most amenable to inspection, that the equipment is suitable for the task, and that the operator is alert and well rested. 

Table 7 gives the allowance for monotony. In the author s opinion, allowances for monotony, boredom, lack of a feeling of accomplishment, and the like are questionable. These factors are unlikely to cause fatigue and thus increase time/cycle. These factors primarily reflect unpleasantness and thus should be reflected in the wage rate/hr rather than the time/unit.

Liking scores were submitted to ANOVA per group with position in the series (rather than product) and subject as factors. Results showed no significant effect of position (Fposi on = 0.96 p = 0.44). In other words, when asked to rate seven samples, elderly people, and even dependent elderly people, did not exhibit any boredom or fatigue effects (Fig. 23.4). 

An excessively low level of arousal will lead to boredom. This is usually found in repetitive jobs devoid of any change (production lines with short activity cycles) and especially in situations where the following factors come into play ... 

These factors have a significant effect on health and safety. Some of them, normally involving the personality of the individual, are unchangeable but others, involving skills, attitude, perception and motivation can be changed, modified or improved by suitable training or other measures. In summary, the person needs to be matched to the job. Studies have shown that the most common personal factors which contribute to accidents are low skill and competence levels, tiredness, boredom, low morale and individual medical problems. 

The root cause is the condition that allowed the immediate cause to develop. These factors can be divided into personal factors and job-related factors. Personal factors inclnde lack of skill, lack of training, physical limitation, and mental issues such as nervousness or boredom. Job factors include inadequate engineering, maintenance, normal wear, or maybe abuse of the machine. 

Human performance in identifying and sorting organisms is affected by several psychological factors (a) the human short-term memory limit of five to nine items, (b) fatigue and boredom, (c) recency effects where a new classification is biased toward those in the set of most recently used... 

Factors affecting situation awareness Two factors that affect situation awareness are workload and stress. Unusually high or low workloads are considered to potentially impact performance of humans to a certain degree [. Low workload can result in boredom with consequent inattentiveness, significantly reduced motivation, and lower vigilance. Furthermore, when less attention is being given to workplace conditions or situations that, in turn, can lead to poor situation awareness. 

Category III Personal factors. These are knowledge, tiredness, boredom, environmental awareness, environmental and operational stress, morale, recent practice, and distraction.
