What are 3 characteristics of cognitive psychology?
Cognitive Psychology
- Uncovers laws of information processing and behavior through experiments
- answers fundamental questions
- no requirement for application
What are 3 characteristics of Human Factors?
Human Factors:
- apply knowledge by designing systems that work
- accomodate the limits of human performance
- directly applied problems
What is the combination of human factors and cognitive psychology called?
Engineering Psychology
Human factors is …?
Human factors is the study of interaction between humans and systems in order to improve
- performance
- safety
- health
- usability
what are 2 disciplines related to engineering psychology?
- Ergonomics - more focused on physical aspects
- cognitive engineering - AI
name 8 goals of human factor engineering
- development of generic knowledge
- enhance efficiency (productivity)
- ensure safety and reduce error
- assure tasks are within human capability
- increase user satisfaction
- gain market acceptance
- reduce costs (economic/legal/social)
- development of tools and equipment
what are 3 low cost applications of human factors?
Low cost:
- consultancy
- expert review
- tests
4 more expensive human factor applications
expensive:
- user centered design
- complete task analysis
- surveys
- experimental research
what are 6 benefits of human factors
benefits of human factors:
- prevention of accidents
- prevent compensation payments
- less support for customers
- less sick leave, higher job satisfaction
- higher productivity, more efficiency
- lower cost for training and instruction
what is the overriding methodological principle in human factors?
user centered design
> find a system that supports the users needs rather than making a system to which the user has to adapt
what are 3 general guidelines when designing a system?
- early focus on the user and tasks
- empirical measurements focusing on quantitative performance data
- iterative design using prototypes
what is the purpose of front-end analysis?
front-end analysis
> understand the users, their needs, and the demands of the work situation
what are 3 common types of front-end analysis?
- user analysis
> define who will be the users
- environment analysis
- function and task analysis
> function: determine the functions of the system
> task: determine specific tasks the user has to complete
why is it important to also determine the goal of the system?
because it may also be reached using a different system
why is it often difficult to discriminate between a function analysis and a prelinimary task analysis?
a preliminary task list does not include a detailed description of what the person actually does
> general tasks often similar to functions
