PSYCHOLOGY
A flicker or blank interval removes the motion cue that normally reveals a change, forcing attention to compare before and after. Details outside that focus may not be retained well enough to expose even a large alteration.
When attention is occupied by a demanding task, a fully visible unexpected object may never reach awareness. Inattentional blindness reveals the limits of selective attention.
The misinformation effect occurs when misleading post-event details enter later reports. Memory remains useful, but reconstruction and source confusion can alter specific details.
Delayed review replaces easy familiarity with effortful retrieval. Repeatedly reconstructing a memory at useful intervals strengthens long-term access.
An earworm is a musical fragment recalled without intention. Recent exposure, familiar melody, memory cues and attentional state all influence when it appears.
The IKEA effect describes our tendency to assign extra value to objects we helped create or assemble.
