Lecture 6- What Happens To The Information We Ignore Flashcards
With dichotic listening results, participants shadowed
Attended message easily
With dichotic listening results, when asked about unattended message
Physical characteristics were reported but not content
With dichotic listening results , if results were in a foreign language or reversed speech
It was rarely noticed
Broadbent’s filter theory states filtering occurs before
Stimuli are analysed to the semantic level
Parts of the filter model
- Sensory store.
- Filter.
- Detector.
- Short term memory
What does the sensory store do
Holds incoming information for a short period of time
What does the filter do
Analyses messages based on physical characteristics
What does the detector do
Information is processed to determine meaning
What does the short term memory do
Holds information for general processing
What does Triesman’s attenuation model believe happens to unattended messages
Attenuated rather than lost completely
Words need to meet a certain threshold of signal strength to be
Detected
Late selection models believe that both attended and ignored inputs are processed to
Stage of semantic analysis
Late selection models can explain
- Response competition interference
- Negative priming
What is negative priming
Responses to previously ignored stimuli are slowed
What is response competition interference
Incongruent distractor in irrelevant location slows RT
