Cognitive 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
the scientific study and body of knowledge of human abilities, limitations, and characteristics for the appropriate design of living and work environments.
Ergonomics
Ergonomics has existed as a profession for over 50 years, helping people to succeed in their jobs by means such as: (Cite 4)

___________ was one of the pioneers of “interactive systems engineering”, and advocated the notion of “user-centered designs”
Enid Mumford
[ISE UCD]
There are 2 criterias for developing user centered design.
– Task analysis (Is the evaluation of cognitive task demands}
– Analyzing motor control cognition during visual tasks (operating machinery attention evaluation)
True or False.
Cognitive ergonomics is a division of ergonomics (human factors), a discipline and practice that aims to ensure appropriate interaction between work, product and environment, and human needs, capabilities, and limitations.
True
________ is a cognitive approach that is often equated with contemporary cognitive psychology
Human information processing model
_________ for particular tasks describe the flow of information through the various stages and predict response times, error rates, error types, and other aspects of human performance.
Information processing models
___________ refers to the cognitive limitations of consumers
Bounded rationality
According to the bounded rationality, we make suboptimal decisions due to 3 factors:
which are?
– Cognitive limitations (Like self)
– Imperfect information (Sir ong)
– Time constraints (deadlines)
True or False: When faced with simple choices, consumers may opt to “satisfice” instead of spending time and effort analyzing the situation – leading to a sub-optimal choice.
FALSE. must be faced with COMPLEX CHOICES. not SIMPLE
_____ refers to our inability as
humans to process information in an optimal manner. In other words, we are unable to consider all available factors in our decision making.
Cognitive limitations
____ refers to the LACK of information a consumer has. Not many consumers likely to spend hours researching what it is and how it affects the performance of their decisions.
Information Imperfections
______contricts our ability to process and anlyze a situation and come to an optimal decision
Time constraint
Theory of Bounded rationality is devloped in what year?
- Simon
Summarize Theory of Bounded Rationality
- Cant optimize decision making
- Satisfaction over perfection
- Lack of info
- limited memory storage
- cant oresee all the possible effects of options
- follow heuristics rather than algorithims
True or false: the Theory of Bounded Rationality describes following algorithms rather than heuristics
FALSE FALSE FALSE.
Heuro over algo ang finofollow. which is not ideal, but describes theory of bounded rationality
Theory of human error is developed by _____ during _____
– By Reason (last name niya toh)
– 1990
_____ describes an (in) action that was not intended / desired by a set of rules or an external observer / that led the task or system outside its acceptable limits
- di sinasadya, di katanggap tanggap di sapat
Human error
Describe Slip, Lapse, and Mistake.
Slip - Attentional Failures (e.g. nagmura sa harap ng prof)
- Lapse - Memory failures
- Mistake - Rule based / Knowledge based mistakes (wrong answers in tests)
Aims to enhance HUMAN-COMPUTER INTERACTION by using neural correlates to better understand situational task demadns
Neuroergonomics
_________ is an emerging field that investigates the human brain in relation to behavioural performance in NATURAL ENVIRONMENTS and everyday settings
Neuroergonomics
True or False (With identification hehe)
Neuroergonomics is summarized by ________ “sci study of brain mechanism and psychological and physical function of humans in relation to TECHNOLOGY, WORK, AND ENVIRONMENT”
Raja Parasuraman
True true true
Cite 3 application of Cogni ergonomics
– Designing a software interface to be EASY TO USE
– Designing icons and VISUAL CUES so that majority of people will understand and ACT in the intended manner
– Design an airplane cockpit or nuclear powerplant control system so that the operators WILL NOT MAKE CATASTHROPIC ERRORS
In Physical Ergonomics. “The job fits the man”
what is Cogni Ergonmics?
“Mind is as confortable at work as the body”
True or false. If the physical surroundings reflect and support their natural cognitive tendencies, there will be more errors and performance & productivity – negative boost
FALSE.
If physical reflect cogni tendencies. LESS ERRORS AND MORE POSITIVE BOOSY IN PERFORMANCE AND PRODUCTIVITY
Indicates different types of _____________—- the mental processes/ functions scuh as perception, attention, and memory, which is what the mind creates.
Cognition
True or false. The mind is a system that creates representations of the world so that we can act within it to achieve our goals. This indicates how our mind operates, creating representations, and its functions, enabling us to act and to achieve goals
TRUE
____ is the study of mental processes, which includes determining the characteristics and properties of the mind and HOW IT OPERATES.
Cognitive psychology
2 questions
Who created an experiment to determine HOW LONG IT TAKES for a person to MAKE A DECISION?
It is determined by measuring what?
– Donders (WITH S) (1868)
– reaction time
Describes how long it takes to respond to the presentation of the stimulus.
Reaction time
How was donder’s experiment done? (explain in detail)
By measuring “Simple reaction time” and “Choice reaction time”
Simple reaction time – asking participants to push a button as rapidly as possible when that saw a light goon (no need to think)
Choice reaction time - using 2 lights and asking participants to push the left button when they saw the left lighT, the push right when they saw the right light go on
This is to determine how much time it takes for a person to DECIDE WHICH TO PUSH (WHICH KEY TO PUSH) during Choice reaction time
Donders concluded in the experiment that the decision-making process took ___________________( how long?)
one-tenth of a second
_________ experiment is important because it was one of the first cognitive psychology experiments and because it illustrates something extremely significant about studying the mind. (Mental responses cannot be measured directly but must be inferred from behaviour
Donders’s experiment
What is the formula of time to make a decision?
Choice reaction - simlple reaction time = time for decision making
Who establish “STRUCTURALISM” and during when?
He also founded the first laboratory of scientific psychology
– Willhelm Wundt (Substantial contribution)
– 1879 (11 years after donders’s experiment
According to _______, our overall experience is determined by combining basic elements of experiment called __________.
– Structuralism
– Sensations
Wundt wanted to create a _______________, which would include all the basic SENSATIONS involved in creating experience.
PERIODIC TABLE of the MIND
Wundt thought he could achieve a science description of the components of experience using _____________, a technique in which trained participants described their experiences and thought processes in response to stimuli
Analytic Introspection
________ was interested in determining the nature of memory and forgetting - specifically, how rapidly information that is learned and lost overtime. developing a quantitative method for measuring memory.
Hermann Ebbinghaus (1885’1913)
How was Ebbinghaus experiment done?
He himslef is the responded. he repeated list of 13 nonsense syllables at a constant rate . His objective Is to determine number of repititions necessary to repeat list without errors
True or false:
Long break intervals = fewer repetitions necessary to relearn list of nonsense syllables (in ebbinghaus’s experiment)
FALSE
short break intervals = fewer repitions necessary.
Ebbing hause used a measure called ______, to determine how much was forgotten after a particular delay?
What is the formula??
- Savings
- Formula: Savings = Original time to learn first - Time to relearn list after delay
The decrease in savings (remembering) with increasing delays indicates that forgetting occurs rapidly over the ________ and then occurs more _______ (Slowly or fastly?) after that.
– first 2 days
– Slowly
Fogetting occurs rapidly in the first 1 to 2 days after orignila learning
___________ one of the early american psychologists (not a student of wundt) taught harvard’s first psychology cource and made significant observations about the mind in his textbook, PRINCIPLES OF PSYCHOLOGY.
When?
William James (1890)
How was william james’s Principles of psychology observed/studied?
develop observations based on the functions of his own mind, not experiments.
