Thoretical Perspectives 2 Flashcards
gibson presented the concept as the affordances of the environment are what _
it offers the person, what it provides, either good or ill
gibson (1979)
what did the usb stick with 3 sides meme try to say
*maybe more about how well we can interact with objects
list the objects with poor affordance (class activity)
- claire’s tv remote(menu button in middle rather than enter)
- sharpener
- card holder
- matreshka marker
list the objects with good affordance (class activity)
- onion goggles
- tea steeper
- claw clip
- standard can opener
- hand sanitizer, lotion
- apple mouse
- tapemeasure
- pen/pencil
- mug
- plastic takeout container
- toy car
- mittens
- pencil case, airpod case, glasses case
- calculator
-lip oil - minute maid bottle
- glute tape
list the objects with mid affordance (class activity)
- little carabiner
- aesthetic red can opener
- chargeable hand warmers
in class we discussed some ‘hints’ that objects can give:
- handles = cue to grasp, tend to pick up handle first esp with sharp things (even if non dominant hand)
- shouldn’t need lots of labels, but safety ok
object affordance is based on **
*individual, previous experience, can also vary based on population
define rate limiter
an individual constraint or system that holds back or slows the emergence of a motor skill because it develops slower than other systems
*maturationists focus on CNS as the only rate limiter
describe the development of systems
5 graphs, 4 graphs with systems and one representing behaviour - combines all of these, interacting with those around us
system 1 graph: as time passes, system remains the same
system 2 graph: steep increase, then flattening (like staircase)
system 3 graph: gradual increase to plateau
system 4 graph: stepwise increase but at angle
define body scaling
the process of changing the dimensions of the environment or an object in relation to the structural constraints of an individual
*affordances can change as ppl change
summarize the maturational perspective
biological development, CNS maturation
summarize information processing
environment as the main force
summarize ecological theorists
interaction between all constraints (dynamical systems and perception-action approaches)
we have no had a paradigm shift since the _ perspective
ecological
