STIMULUS = basis of the physical properties of the input, RESPONSE = basis of mental categories that do not share physical property

What does the filter theory not allow?
Divided attention
16 of 30
What was the finding of Gray & Wedderburn (1960) in a split-span procedure?
Subjects grouped items for recall on the basis of meaning
17 of 30
What is the difference between the early filter model and the filter attenuation model?
Although the unattended message is not fully analysed for meaning, small familiar info (e.g names) can get through to deep analysis
18 of 30
In the filter attenuation model, why are names allowed semantic analysis?
Low activation thresholds
19 of 30
What is the central claim of late-selection theories (e.g Deutsch Deutsch, 1963)?
All messages are analysed to the level of response set, selection of attention based on MEANING. Contradicts early-selection models
20 of 30
What is the concept of 'filtering'?
Selection of events with particular physical features = processing
21 of 30
What is the concept of 'Categorising'?
Only processing events which belong to a particular category. Takes practice to establish categories/members
22 of 30
What is the concept of 'Pigeon-holing'?
Once a category is establish, members are selected on the basis of bias to the category rather than on physical features
23 of 30
Which concept did Rabbitts (1964,1967) letter search task support?
Categorising

According to Kahnemans capacity model, why does the dual task decrement arise?
The task requires more resources than currently available
25 of 30
What is the main premise of Kahnemans capacity model?
Any task demands capacity from the limited mental pool, relative to the persons experience
26 of 30
What is the core concept of Lavies perceptual load model?
If the load on perceptual analysis is slight, then there is no filtering and non/targets are processed, When the load is heavy, there will be full capacity on filtering (gating)
27 of 30
What was the critical result behind Lavies perceptual load hypothesis?
The compatibility effect only arose for the low load condition (small no of non-targets), no corresponding effect for high load condition
28 of 30
What is change blindness?
Failure to detect changes in the immediate visual scene
29 of 30
What is inattentional blindness?
Failure to see highly visible objects even though we are looking at them
