My paraphrase of the 2013 study’s findings:
- We pay attention to the present through the windows of perception that we’ve developed from our past;
- The rest of the world is blocked by our consciousness’ perceptual thresholds.
It was good to read an attention study that didn’t zap the subjects’ brains.
