Which researcher proposed the filter theory of selective attention in 1956?
AWertheimer in his Gestalt theory of grouping
BTriesman in her attenuation-based model of attention
CJohnston and Heinz in their flexible-stage model
DBroadbent in his early bottleneck model of attention
Answer & Solution
Correct answer: D. Broadbent in his early bottleneck model of attention
1. The chapter introduces three theories of selective attention in order of historical development.
2. It states that filter theory was developed by Broadbent in 1956.
3. Triesman's filter-attenuation theory came later in 1962, and Johnston and Heinz proposed multimode theory in 1978.
4. Wertheimer is associated with Gestalt psychology, not attention theory.
5. So the 1956 filter theory belongs to Broadbent.
