Human brain recalls visual features in reverse order than it detects them: Study challenges traditional hierarchy of brain decoding; offers insight into how the brain makes perceptual judgements

But lower-level memories – ‘this candidate said this or that’ – are not as reliable. In a second task, the researchers changed the angle of the line to 53 degrees. advertisement Previously held models of decoding predicted that in the two-line task, people would first decode the individual angle of each line (a lower-level feature) and the use that information to decode the two lines’ relationship (a higher-level feature). But during decoding, when participants were asked to report the individual angle of each line, their brains used that the lines’ relationship – which angle is greater – to estimate the two individual angles. This was striking evidence of participants employing this reverse decoding method, said Dr. Qian.
