I've always thought it's a bit weird, but today I just had a conversation about it with a friend who doesn't have the same problem. Well, she's probably an I__J of some sort.
I live in Japan now, and Japanese is my second language, which does contribute to me not hearing stuff clearly. But I've actually always had the same problem when I lived in US & the Philippines and used English, which is my first language. When I listen to people, I always try to be attentive. But I frequently not hear words right, and have to ask the other party to repeat what he/she just said. Often I'd hear the sound, but either I'm missing some parts of the sound or I can't put the sound together into words in my brain. In fact, when I used English all the time, I think the sentence I used the most in every day conversation was "What?" or "Huh?" (Yeah, they're not even sentences). Especially when I talk on the phone, I was often lost and don't understand what the Citibank lady just asked me, and I would need her to repeat the question even though I perfectly understand English.
I'd like to know if this has something to do with INFP cognitive function or something else entirely.
(I mean, I am quite attentive in listening to abstract forms of sound, like music. But even in that, I'm not super well-trained in recalling the context of the sounds correctly.
Also, when I read words aloud from a book or an article, I often don't catch the content of the text because I'm focusing so much on looking at the right letters and making the right sounds. Especially with alphabet and kana, where the individual letters represent sounds rather than concepts.)
