2 Flashcards
Most visual functions are adult like by the age of….
12
What is Clearness of Vision
Visual Acuity
no depth perception younger than how mnay months
(Visual Cliff)
6
where are receptors located?
Skin
Under the Foot
Discrimination or Memory? which one is first
Discriminate= first
Spatial Awareness
Optical illusions are
Intrasensory or Intersensory
Intersensory
What experiment got babys to walk on a platform
Karon Adolph experiment
What type of phenomenon is a social setting
Cocktail party phenomenon
Example of Body Drag
Crawling
- abdomen clear (stomach not touching floor) ex: crawling
Creeping
What is the hardest action to do
Grasp/ Release/ Reach out
Releasing
how many phases of manuel control are there?
4
Direction is dictated by Biological or environment
Biological
Strength is dictated by Biological or environment
environment
When is the Sensitive Period
2-8 weeks or
1st Trimester
Environmental agent that can cause birth defect or kill the fetus
Teratogen
Low Birth Rate is less than how many pounds?
5.5
What is the Growth Hormone
Pituitary Gland (PH)
What does the Thyroid Release?
Thyroxine
most important modalities for perceptual processing
Visual and Kinesthetic
An objecr continues to exist when they are no longer in view
Visual Function/ Object Permananance
A not B error
Ability to distinguish an object from its surrounding back
Figure- Ground Perception
Ability to judge distance of an object from the sheld
Depth Perception
Environemnt that can be seen without a change in the fixation of the eye.
Field of Vision
Awareness of movement and body position
Kinestheseis
Which comes first?
Discrimination or Memory?
Discrimination
Ability to attend to relevant information
Selective Attention
Limitations in the capacity to handle information from environment
Divided Attention
Recognition or Recall
Noticing whether a stimulus is identical or similar to one previusly experience
Recognition
Recognition or Recall
The more advanced form of memory, involves remembering a stimulus that isnt present
Recall
Early processing Abilities
Reaction to stimulus declines
Habituation
Basic Measure of processing Speed
Reaction Time (RT)
Hick’s Law or Fitts Law
Processing time increases as information load (complexity) increases RT
Hick’s Law
Hick’s Law or Fitts Law
When performers attempt to do something more quickly, they typically do it less accurately (Speed- Accuracy Trade off)
Fitt’s Law (Not fit to do it)
Schema Theory:
GMP stands for
Generalized Motor Program
-Formulate movement plans to help you have a desired action
-Formulate movement plans to help you have a desired action
Recall, Recognition, Motor
Variability in practice promotes general
(GMP-Schema Theory)
Theories of Motor Control:
Motor programs control groupings of muscles w/ associated joints
Degrees of Freedom
Synergies (muscle groupings)
Coordinative Structures
Dynamical Systems
Neuronal Group Selection
Coordinative Structures
Lies under what model?
You can either limit behavior, or faciliate behavior
Newells Constraint Model
Processing Speed and Movement Time
(As you get older its harder to do Complex tasks)
Psychomotor slowing
Voluntary or Involuntary
Reflexes are
Involuntary
Primitive
Postural
Locomotor
are 3 types of what?
Reflexes
Primitive
Primitive
Postural
Locomotor
Crawling, Stepping, Swimming
Locomotor
