Final answer:
Brad was able to hear Monica say his name because the semantic filter of the dual filter model picked up his name in an automatic process. This demonstrates the cocktail party effect, where a person can hear a personally relevant stimulus, like their name, despite other distractions.
Step-by-step explanation:
The question refers to the scenario where Brad, while in deep conversation with Edwin, is able to hear Monica mentioning his name from across the room. This phenomenon can be explained through selective attention in psychology, particularly the concept known as the cocktail party effect. This effect demonstrates that people can focus their auditory attention on a particular stimulus while filtering out a range of other stimuli, much as a partygoer can focus on a single conversation in a noisy room.
The answer to the student's question is: D) The semantic filter of the dual filter model picked up his name in an automatic process. This choice describes the process by which our attentional systems are designed to pick up personally significant stimuli, such as our names, even when we are not consciously listening for them. This process is automatic, in other words, it doesn't require conscious attention to operate.
