(110 cards)
Theory
Mental viewing
Proposed idea or plan
Statement that explains observable phenomenon
Model
Small copy or imitation of a design
Hypothetical description based on analogy
Explains concept or object it represents
Seeing all parts as a whole
Systems Theory
Ludwig Von Bertanlanfty
Studying human behavior through “wholes” that fiction “holistically” because of their interdependence of their parts
System
Whole that functions as a whole due to interdependent parts
Equifinality
Systems from simple to complex
Energy pool
Source of power that is needed for systems to function
Nonsummativity
Degree of interrelatedness among systems parts
⬆️ nonsummativity = ⬆️ interdependence of components
Systems need to function
Focal unit
Particular part of system interest in studying
Ex. Cell, two people interacting
Microsystem
Looks at one small focal unit
Mezzosystem
Looks at several Microsystems
Macrosystem
Looks at large or complex interrelationships
Ex. How nervous system and enforcing system interact
Subsystem
One of the lesser systems that make up total
Suprasystem
Any subsystem that is outside the system under study
Open system
Ongoing dynamic exchange of data with the environment and other systems
Closed system
Does not exchange data with environment
Self-contained
Slow to change
Ex. Chemical reactions, rocks
Interface
Space outside system acts as medium to transfer info, energy, etc (environment)
Entropy
System to become disorganized and nonfunctional
Negentropy
System maintains itself homeostasis
Dynamic process
Input/output channels
Ways the system exchanged data with the environment
Throughput
Allows input to enter and output to leave through semipermeable membrane
Outer edge of system
Feedback loop
Both positive and negative feedback enter and leave the system
Positive feedback
Lead to change
Goal: improvement
Negative feedback
System reaches peak in functioning
Maintains level
Adaptive behavioral response
Coping process
Allows person to adjust to stimuli (input)
Maintain state of health
