Unit 3 Flashcards
What does the CBS do
Processing info and connects to the PNS
What’s the function of the PNS
Carry info around the body
What term is used to describe parasympathetic and sympathetic
Antagonistic
What’s the function of the cerebral cortex
Receives sensory info and coordinates voluntary movement and decision making
What’s the function of the Limbic system
LTM, emotion, behaviour and motivation
Function of the cerebellum
Balance and coordination
Function of the medulla
Involuntary movements like digestion and breathing
What’s the function of the corpus callosum
Bridge of tissue deep within the brain to help info be transferred between the two hemispheres
What’s the function of the association area
Controls intelligence at the front of the brain
What’s the function of the sensory area
Impulses from skin organs and muscles
What’s the function of the Motor area
Impulses to skeletal muscle
What’s the definition of perception
Process by which the brain analyses and makes sense out of incoming sensory info
What’s segregation of objects
Brain segregates the image into the figure and the background
E.g. A vase or 2 people
What’s relative size
The brain uses visual cues such as relative size to make sense out of visual images
Like the further away an object is the smaller it appears
What’s super imposition
When the image of one object blocks the image of another. The blocked object is perceived further away
What’s relative height in field
When a group of objects have their bases below a visible horizon. The Lower bases appear closer
What’s binocular disparity
Each eye sees an object from a different position so the brain fuses it together
What’s perceptual constancy
Our visual perception of our surroundings take into account sizes and shape of well known objects
Like a door closing we accept it’s not changed size
What’s recognition
Overall shape is more important than detail.
Like woman or old lady
What happens to items in the sTM
Decay or displaced
How can you put STM into LTm
Rehearsal, organisation and elaboration
What’s the serial position effect
Recalling the first and last
What’s chunking
Improve STM and helps to make things easier to remember
What’s a contextual cue
Signal or reminder e.g. A familiar smell
