according to the broadbent’s filter model what is sensory memory?
holds all incoming information for a fraction of a second
transfers all info to next stage
according to the broadbent’s filter model what is what is the filter?
identifies attended message based on physical characteristics
only attended message is passed on to the next stage
according to the broadbent’s filter model what is the detector?
processes info to determine high level characterisitcs of the message
according to the broadbent’s filter model what is short term memory?
receives output of detector
holds info for 10-15 seconds and may transfer it to long term memory
According to treisman’s attenuation model what is Attenuation?
both physical characteristics and meaning can be used to select attended versus unattended messages
attenuator acts as leaky filter
According to treisman’s attenuation model what is the attenuator?
analyzes incoming messages in terms of physical characteristics, language, and meaning
