Selective Attention: The ability to focus on specific stimuli while ignoring others. In this case, the concert-goer's selective attention is focused on enjoying the loud music, making it difficult for them to pay attention to their phone ringing.
Sensory Adaptation: When our senses adjust and become less responsive to constant or repetitive stimuli over time. If the concert-goer has been exposed to loud music for an extended period, their ears may have adapted and become less sensitive to other sounds like their phone ringing.
Signal Detection Theory: A theory that explains how we detect weak signals in the presence of background noise or distractions. In this situation, the loud music acts as background noise that makes it harder for the concert-goer's brain to detect and interpret their phone ringing signal accurately.
