The dichotomy of speed- and accuracy-related abilities in face and object cognition and their neurocognitive mechanisms
Final Report Abstract
(1) Faces stand out as a specific category of objects; other special object categories are vehicles, which relate to the expertise that some persons acquire with this special object category. Importantly, for research purposes of contrasting social versus non-social stimuli, houses belong to a representative category of non-face objects and can be taken as a proxy for comparisons with faces. (2) The differentiation between faces and objects in accuracy tasks but not in speed tasks was confirmed on the performance level. A similar differentiation could be found on the neural level for indicators of structural analysis (N1/N170) of faces and houses. (3) The brain-behaviour relationship showed that faster face-specific processes for structural encoding of faces are associated with higher accuracy in both, perceiving and memorizing faces. Moreover, in difficult task conditions, qualitatively different processes are additionally needed for recognizing face and object stimuli as compared with easy tasks. The difficultydependent variance components of the N170 amplitude were related with both face and object memory performance.
