Who proposed the filter model of attention, which outlines processing stages of the mind?

• A. John Watson
• B. Donald Broadbent
• C. B.F. Skinner
• D. George A. Miller

Answer: (B)

The filter model of attention was proposed by Donald Broadbent, who is a significant figure in the field of cognitive psychology. Broadbent's model, introduced in the 1950s, suggests that information processing in the mind occurs in stages and involves the selection of stimuli through a "filter." This filter allows only certain information to pass through for further processing while blocking other stimuli, which helps explain how individuals can focus on a specific task or conversation in a noisy environment. This concept has been fundamental in understanding how attention works, highlighting the limitations of our cognitive resources and the need for selective attention. The other figures mentioned played important roles in psychology but did not propose the filter model. John Watson is known for his work in behaviorism, focusing on observable behaviors rather than cognitive processes. B.F. Skinner, also associated with behaviorism, emphasized operant conditioning and behavior modification, while George A. Miller contributed to cognitive psychology with concepts like the "magic number seven," regarding memory capacity, rather than attention models.
