sensation
the detection and input of environmental stimuli by the sense organs and the conversion of this sensory information to electrochemical energy to be sent to the brain for perception
sense organs
specialised organs in the body containing sensory neurons functioning as sensory receptors
three stages of sensation
reception, transduction, transmission
reception
when the presence of a stimulus/ sensory information is detected by receptors in sense organs
transduction
the conversion of sensory information into electrochemical energy
transmission
electrochemical energy transported from sensory receptors to brain
perception
mental representation that the brain creates using information provided by sensory information form sensory organs via electromechanical energy, allows the understanding of the world and gives meaning to the stimuli we take in.
3 stages of perception
selection, organisation, interpretation
selection
crucial features of information are filtered for further processing. insignificant content is disregarded.
organisation
selected information is categorised allowing for the establishment of meaningful patterns
interpretation
involves assigning meaning to sensory stimuli so we understand what it represents about the external world. can be influenced by past experiences.
atkinson and shiffrin: what model , year and draw it
1968 multistore model of memory
memory
the encoding, storage and retrieval of sensory information
processes of memory: encoding
conversion of sensory information so that it can be processes by the brain and entered into memory
processes of memory: storage
maintaining/ retention of encoded information into a memory store
processes of memory: retrieval
processes of getting information back from long term memory to be used in working memory and into consciousness
sensory register
allows individuals to retain impressions of sensory information for brief time
