In a study,subjects listened to two different sentences played at the same time in opposite ears.In the right ear,the subjects heard,"Jack went shopping for some fruit in the grocery store" in a woman's voice;in the left ear,the subjects heard,"Sally jumped up from her seat to get the phone call" in a man's voice.The subjects were asked to repeat what they heard in the left ear.When asked about the message in the right ear,all the subjects could remember was that the message was in a woman's voice.Therefore,researchers conclude that,although both messages were perceived,subjects were not able to attend to both messages.This is evidence:
A) of a deficit in attention.
B) supporting a central bottleneck.
C) supporting automaticity
D) of the binding problem.

The study supports a central bottleneck, which means that our perceptual and cognitive resources limit our ability to process multiple streams of information simultaneously. The subjects were unable to attend to both messages because of this bottleneck, which restricted their ability to focus on both messages at the same time. This suggests that our attentional resources are limited and that we cannot process all of the incoming sensory information at once. Choice A (deficit in attention) is related to choice B, but it does not capture the specific mechanism of the central bottleneck. Choice C (automaticity) is not supported because the study shows that conscious attention is required to attend to and remember the message. Choice D (binding problem) is not supported because the study did not address the issue of how different features of sensory stimuli are integrated into a unified percept.
