14. The Information Processing Systems Flashcards
The Information Processing Systems
If a ball is thrown to an observer, what is detected by the senses to attract attention to it
STIMULI
The Information Processing Systems
Depending on the level fo attention generated by stimuli, it can be acted upon in what 3 ways;
[ ] Consciously
[ ] Sub-consciously
[ ] Ignored
[ ] Incoherently
[ ] Directly
[ ] In-directly
[X] Consciously
[ ] Sub-consciously
[X] Ignored
[ ] Incoherently
[X] Directly
[ ] In-directly
The Information Processing Systems
Reactions to stimuli can be handled simultaneously
TRUE or FALSE
TRUE
- WHile reactions to many stimuli can be handled simultaneously, a significant bottle neck occurs when conscious decisions have to be made before an action is taken
2
The Information Processing Systems
An individuals performance at a task is directly related to their level of what
AROUSAL
3
The Information Processing Systems
- Complex tasks are better performed when the arousal state is HIGHER or LOWER
- Less complex tasks are better performed when the arousal state is HIGHER or LOWER
- Best performance is achieved with what level of arousal
- LOW
- HIGH
- OPTIMUM
- Whilst this might seem to conflict with what we expect, being over aroused can degrade energy and ability to concentrate, and the decline of perofrmance is very rapid when the threshold is exceeded
- An optimum level of arousal is required for best performance
- Over arousal and under arousal will degrade performance
3
The Information Processing Systems
What does the body use to adapt itself to a task and provide the correct level of arousal. i.e. Adrenaline is an example
HORMONES
3
The Information Processing Systems
- The level of arousal in the cruise will be HIGHER or LOWER
- The level of arousal during landing will be HIGHER or LOWER
- LOWER
- HIGHER
3
The Information Processing Systems
An emergency situation or someone who is suffering from sleep deprivation may have less than adequate performance. What is said to be adversely affecting the pilots state of arousal
EXTERNAL FACTOR
3
The Information Processing Systems
- Over-arousal is known as HYPERVIGILANCE or HYPOVIGILANCE
- Under-arousal is known as HYPERVIGILANCE or HYPOVIGILANCE
- HYPERVIGILANCE
- HYPOVIGILANCE
- Remember
- Hyper coaster goes high
- Hippos (hypo) are low under water.
- Hyper is high, hypo is low, in this case over being high, under being low
4
The Information Processing Systems
The causes of hyperviligance are;
[ ] Excessive caffine consumption
[ ] High workload
[ ] Environmental stressors (heat and noise)
[ ] Emergencies
[ ] Sleep deprivation
[ ] Over worked
[ ] Excessive caffine consumption
[X] High workload
[X] Environmental stressors (heat and noise)
[X] Emergencies
[ ] Sleep deprivation
[ ] Over worked

The Information Processing Systems
The effects of over-arousal are;
[ ] Inability to prioritise between tasks
[ ] Loss of speed and accuracy
[ ] Reduced ability to perform calculations
[ ] Disproportionate narrowing of attention
[ ] Reduced levels of performance on routine tasks
[ ] Narrowing of visual field
[ ] Complete tasks faster but less accurately
[ ] Behavioural changes
[ ] Reduction in mental resources
[ ] Reliance on automatic patterns of behaviour
[ ] Inability to prioritise between tasks
[ ] Loss of speed and accuracy
[X] Reduced ability to perform calculations
[X] Disproportionate narrowing of attention
[ ] Reduced levels of performance on routine tasks
[X] Narrowing of visual field
[X] Complete tasks faster but less accurately

[X] Reliance on automatic patterns of behaviour

The Information Processing Systems
A pilot who is tired and suffering from hypovigilance will have a temporary INCREASE or REDUCTION in ability in a noisy cockpit
INCREASE
- A tired pilot will work better in a noisy environment for a short time
- This counters the effects of the tiredness causing hypovigiliance for a short period
5
The Information Processing Systems
In some multi-crew operations there may be opportunities for crew members to take short sleeps or naps to help counter the risk of hypovigilance.
- Naps should not exceed ____
- Recovery from a nap to full wakefulness takes approximately ____
- 30-45 MIN
- 5 MIN
