Module 9: Human Factors
- What is the appropriate first aid action for someone suffering from hypothermia?
Options:
A) Warm them up.
B) Feed them sweet things because of their diabetes.
C) Give them a drink because of dehydration.
Correct Answer: A) Warm them up.
Explanation: Hypothermia is a medical emergency caused by prolonged exposure to cold, resulting in a dangerous drop in body temperature. The primary action is to gradually warm the person to restore normal body temperature. - Most engineering-related incidents are often attributed to:
Options:
A) installing dirty connectors
B) installing components incorrectly
C) installing worn or old components
Correct Answer: B) installing components incorrectly
Explanation: Human factors analysis frequently reveals that many engineering incidents stem from incorrect installation of components, indicating issues with procedures, training, or adherence to instructions. - For how long is short-term memory generally effective for recalling about seven items?
Options:
A) 30 to 60 seconds
B) Up to 30 seconds
C) Above 60 seconds
Correct Answer: B) Up to 30 seconds
Explanation: Short-term memory, or working memory, has a limited capacity (often cited as around 7 +/- 2 items) and a short duration, typically holding information for up to 30 seconds without rehearsal. - What is ‘white finger’ (Vibration White Finger)?
Options:
A) A disorder of the finger which may occur through continuous use of pneumatic tools because of reduced blood flow.
B) A reaction when the white blood cells die and contaminate the fingers.
C) A skin disorder caused by extensive contact with oils and solvents.
Correct Answer: A) A disorder of the finger which may occur through continuous use of pneumatic tools because of reduced blood flow.
Explanation: White finger, or Vibration White Finger (VWF), is a vascular disorder caused by prolonged exposure to vibration, such as from pneumatic tools. It affects blood circulation in the fingers, leading to numbness, tingling, and blanching. - When a person is working in an enclosed space (e.g., a fuel tank), why should another person be outside in constant communication?
Options:
A) to provide instructions to the tradesman
B) to ensure compliance with the maintenance manual
C) for safety reasons
Correct Answer: C) for safety reasons
Explanation: Having a ‘top man’ or ‘attendant’ outside an enclosed space is a critical safety measure to monitor the worker inside, ensure their well-being, provide assistance in an emergency, and maintain communication, which is vital for confined space entry procedures. - What is the term for learning a routine through repeated practice?
Options:
A) cognitive learning
B) motor programming
C) episodic memory
Correct Answer: B) motor programming
Explanation: Motor programming is a type of learning that involves the acquisition of motor skills and sequences of movements through repetition and practice, leading to automaticity in performing tasks. - Extreme discomfort experienced by a maintenance engineer due to working in a confined space is known as:
Options:
A) claustrophobia
B) acrophobia
C) agoraphobia
Correct Answer: A) claustrophobia
Explanation: Claustrophobia is the irrational fear of confined spaces. Maintenance engineers working in tight aircraft spaces can experience this, leading to significant discomfort or anxiety. - Which type of memory is most easily influenced by a person’s expectations of what should have happened?
Options:
A) long term memory
B) semantic memory
C) episodic memory
Correct Answer: C) episodic memory
Explanation: Episodic memory is memory for specific events and experiences. It is highly reconstructive and can be influenced by schemas, expectations, and post-event information, making it susceptible to biases and errors. - The inability of the eyes to accommodate sufficiently for near vision is known as:
Options:
A) presbyopia
B) hypermetropia
C) myopia
Correct Answer: A) presbyopia
Explanation: Presbyopia is a common age-related condition where the eye’s lens loses its flexibility, making it difficult to focus on close objects. It is a natural part of aging. - Ultra-short term memory typically has a duration of about:
Options:
A) 10 to 20 seconds
B) 80 – 100 milliseconds
C) 2 seconds
Correct Answer: B) 80 – 100 milliseconds
Explanation: Ultra-short term memory, also known as sensory memory, has a very brief duration, holding sensory information for milliseconds (e.g., iconic memory for visual information) to a few seconds (e.g., echoic memory for auditory information). - Hypermetropia is the medical term for:
Options:
A) short sightedness
B) long sightedness
C) deafness
Correct Answer: B) long sightedness
Explanation: Hypermetropia, also known as farsightedness or long-sightedness, is a vision condition in which distant objects are seen clearly, but near objects appear blurred. - A person with 20/40 vision has:
Options:
A) worse eyesight as a person with 20/20 vision
B) better eyesight than a person with 20/20 vision
C) the same eyesight as a person with 20/20 vision
Correct Answer: A) worse eyesight as a person with 20/20 vision
Explanation: In visual acuity measurements, 20/20 vision is considered normal. 20/40 vision means a person can see at 20 feet what a person with normal vision can see at 40 feet, indicating worse eyesight. - Long-term memory capacity is generally considered to be:
Options:
A) 4-8 years
B) unlimited
C) 12 months
Correct Answer: B) unlimited
Explanation: Long-term memory is believed to have an effectively unlimited capacity, capable of storing vast amounts of information for extended periods, from minutes to a lifetime. - What is the initial stage in the information processing model?
Options:
A) decision
B) memorizing
C) perception
Correct Answer: C) perception
Explanation: Perception is the first stage in the information processing model, involving the interpretation of sensory information from the environment. This is followed by attention, memory, and decision-making. - If information is not rehearsed, it is typically lost from short-term memory within:
Options:
A) 10 – 20 seconds
B) 1 minute
C) 30 – 40 seconds
Correct Answer: A) 10 – 20 seconds
Explanation: Without active rehearsal or attention, information in short-term memory decays rapidly, usually within 10 to 20 seconds. - Attention Getters are communication techniques designed to:
Options:
A) gain the operators attention whilst allowing them to continue with the task in hand
B) make the operator focus his/her attention fully on the task in hand
C) get the operators full attention
Correct Answer: C) get the operators full attention
Explanation: Attention getters are prompts or signals specifically designed to capture the full and immediate attention of an operator, often used in safety-critical communications to prevent errors. - Motor programmes are best described as:
Options:
A) behaviour subroutines
B) require conscious thought to engage
C) are stored as working rules in long term memory
Correct Answer: A) behaviour subroutines
Explanation: Motor programs are learned, automatic sequences of movements or ‘behaviour subroutines’ that can be executed without constant conscious thought, once established through practice. - What function does the nose perform for air entering the lungs?
Options:
A) filters, warms the air into the lungs
B) filters, warms and moistens the air into the lungs
C) filters the air into the lungs
Correct Answer: B) filters, warms and moistens the air into the lungs.
Explanation: The nose plays a crucial role in preparing inhaled air for the lungs. It filters out particles, warms cold air to body temperature, and moistens dry air to prevent irritation and damage to the respiratory system. - A consistent pattern of behavior by an individual is commonly known as a:
Options:
A) the norm
B) habit
C) culture
Correct Answer: B) habit
Explanation: A habit is an acquired pattern of behavior that has become almost involuntary or automatic due to frequent repetition. It’s a regular, often unconscious, way an individual behaves. - In a group discussion, who is most likely to be agreed with, irrespective of the validity of their argument?
Options:
A) the person who repeats the point most times
B) the most argumentative person
C) the person with the highest status
Correct Answer: C) the person with the highest status
Explanation: In group dynamics, individuals with higher status or authority within the group often have their opinions more readily accepted, regardless of the merit of the argument, due to social influence and deference.
