“Your face, my thane, is as a book where men may read strange matters.” (Shakespeare, Macbeth)
A current theory describes the human brain as a “prediction machine”: It posits that our brain is constantly constructing hypotheses of what will happen next. When there is sensory input, it is quickly matched or corrected/updated by comparing it with already existing hypotheses. This process increases the efficiency of our brain – that is, our data processing and reaction abilities.
According to this theory, perception can be understood as a creative process: Besides the sensory impressions, our expectations and experiences as well as our existing knowledge play a key role for the occurrence and processing of our perceptions. But this can also lead to deceptions and distorted perceptions.
In her lecture, Rasha Abdel Rahman, professor of neurocognitive psychology at HU Berlin, discusses neuroscientific studies that show that our knowledge – in the form of learned categories in our native language or personal information – can influence the visual perception of objects and faces and even our visual consciousness.
Rasha Abdel Rahman has been Heisenberg Professor of Neurocognitive Psychology at Humboldt-Universität zu Berlin since 2010. Her research focuses on language production, semantic memory, facial and object recognition as well as the influence of attention, linguistics and emotion on perception. In addition to the Heisenberg Professorship, her honors include the Heinz Heckhausen Young Scientist Award of the German Psychological Society in 2008 and her participation in the DFG Research Training Group on “Clinical and Cognitive Neurosciences” from 1997 until 2000. In 2008, she successfully completed her habilitation, The Semantic System in Object Recognition and Speech Production,“ in psychology at Humboldt-Universität zu Berlin.Close
