Experts at Johns Hopkins shed new light on inattentional blindness, the tendency among us to miss noticing something obvious when our minds are caught up in other things

We live much of our lives in our heads, detached from the here and now – as when we recollect the past, anticipate future possibilities, lose ourselves in a daydream, a novel, or our favourite corner of science [1]: ‘what sets us apart is…a life in the mind, the ability to imagine’ [2]. For most of us, sensory imagery, which allows us to experience the sensory properties of objects in their absence, is a central element of our imaginings [3]. The realisation that ~4% of people lack visual imagery, facilitated by a term with which to describe this, aphantasia [4], while an even higher proportion, with hyperphantasia, enjoy imagery rivalling the vividness of perception, has triggered a recent surge of research.
