Lecture 1 Flashcards
What are the 3 Domains of Ergonomics?
Physical Ergonomics
Cognitive Ergonomics
Organizational Ergonomics
It is concerned with
human anatomical characteristics,
anthropometric characteristics,
physiological characteristics and
biomechanical characteristics
as they relate to physical activity.
Physical ergonomics
____ is concerned with the optimisation of socio-technical systems, including their organisational structures, policies and processes.
Organisational ergonomics
Which Domain of Ergonomics
Relevant topics include
→ human system considerations in communication, human resource management, work design, design of work schedules, teamwork. participatory design. community ergonomics, cooperative work, new work models, virtual organizations. tele-work and quality management.
Organisational ergonomics
_____ is concerned with mental processes such as perception. memory, reasoning and motor response, as they affect interactions among humans and other elements of a system.
Cognitive ergonomics
Which Domain of Ergonomics Relevant topics include mental workload, decision-making. skilled performance. human-computer interaction, human error, work stress and training
as these may relate to the way humans work in systems.
Cognitive Ergonomics
What are the 3 factors that humans are involved in all aspects of technology?
Designers
Users (operators)
Maintenance personnel
What are the problems of technology failure?
- machine failure
- human error
- interaction of humans and machines(system error)
Differentiate Physical Ergonomics Vs
Cognitive Ergonomics in simple terms.
Physical ergonomics focuses on our BODIES
Cognitive ergonomics is interested in what
goes on in our BRAINS
3 Structure of the Brain
Cerebrum
Cerebellum
Brainstem
The ______ (front of brain) comprises gray matter (the cerebral cortex) and white matter at its center.
Cerebrum
The ____ is the wrinkly gray outer covering of the cerebrum.
cerebral cortex
The ______ (“little brain”) is a fist-sized portion of the brain located at the back of the head, below the temporal and occipital lobes and above the brainstem.
cerebellum
Like the cerebral cortex, it has two hemispheres. The outer portion contains neurons, and the inner area communicates with the cerebral cortex.
cerebellum
It is the largest part of the brain, the cerebrum initiates and coordinates movement and regulates temperature.
Cerebrum
What are the 4 lobes of the Brain?
The frontal lobes
The parietal lobes
The occipital lobes
The temporal lobes
It is lobes of the brain that control thinking, planning, organizing, problem solving, short-term memory and movement.
The frontal lobe
It is lobes of the brain that interprets sensory information, such as taste, temperature and touch.
The parietal lobe
It is lobes of the brain that processes images from your eyes and link that information with images stored in memory.
The occipital lobe
It is lobes of the brain that processes information from your senses of smell, taste and sound. They also play a role in memory storage.
The temporal lobe
The _____ is a complex set of structures found on the central underside of the cerebrum, comprising inner sections of the temporal lobes and the bottom of the frontal lobe.
Limbic system
It combines higher mental functions and primitive emotion into a single system often referred to as the emotional nervous system.
Limbic system
What consists of Limbic system?
◦Amygdala ◦Hippocampus ◦Hypothalamus ◦Thalamus ◦Basal Ganglia ◦Cingulate Gyrus
Parts of a Limbic system that has two-lima-bean sized cluster of neurons involved memory consolidation and emotions both our greatest fear and aggression.
Amygdala
Parts of a Limbic system that is a center to learning and memory
Hippocampus
Parts of a Limbic system that :regulates body temperature, rhythm, hunger and helps govern the endocrine system. It helps us feeling pleasure of rewards.
Hypothalamus
Parts of a Limbic system that - is a sensory “way-station” for the rest of the brain, is primarily important due to its connections with other limbic-system structures.
Thalamus
Parts of a Limbic system that - is a group of nuclei lying deep in the subcortical white matter of the frontal lobes that organizes motor behavior.
Basal Ganglia
Parts of a Limbic system that is - located in the medial side of the brain next to the corpus callosum. It is known that its frontal part links smells and sights with pleasant memories of previous emotions.
Cingulate Gyrus
