Stressor, Stress Effects - Direct or Indirect - Coggle Diagram

- - - - • The experience of workload increases relatively continuously.
      - • Ratio of the time required (to do tasks) to the time available (to do them in)
    - - Remediation:
        
        Task Redesign
        
        Display design for the most objectively important tasks
        
        Training a) Component tasks
        b) Task management skills
  - - - What tasks will be affected?
        -Tasks depending on visual input
        -Involving higher level of cognition
        -Long duration missions - sleep debt (truck driver)
    - - Get more sleep
        
        Napping
      - Sleep credits
        
        Gain extra sleep prior to sleep disruption
      - Sleep management
        
        Emphasize the importance of adequate sleep for operational safety
        
        Sleep room
- - - - Threat of loss caused by psychological stressor will make us more motivated to work harder
    - - Heart rate increases, pupil diameter increases when the arousal optimum increse
- - - - repetitive motion disorder
      - Vibration can be disrupt the:
        
        Precision of the hand and arm in operating the tool
        
        body posture
        
        Performance of an eye-hand coordination
        
        Performance visual task
      - Helicopter, ground driller, handheld power saw
    - - Produced by sea swell on a ship, rocking of an airplane in flight, lift and etc.
      - Hard to concentrate due to motion sickness
  - - - Decrements in performance
      - Affecting the efficiency of information processing
      - Heat exposure may leads to dehydration, heat stroke, heat exhaustion
      - Recommendations for remediation: Choice of clothing, redesigned job activity, fans can be employed appropriately
    - - Disruption of coordinated motor performance coordinated by hands and fingers
      - Remediation when cold is escessive:
        
        Appropriate clothing
        
        Gloves
        
        Mittens
    - - Poor air quality is from poor ventilation in closed working spaces
        Effects of poor air quality;
        
        Anoxia = Lack of oxygen especially in high altitudes
        
        Effects on perceptual, motor and cognitive performance
