The processing of spatial frequency and orientation information

摘要: Three identification experiments were completed to disambiguate the associations-between-spatial frequency and orientation information at sensory, decisional, response levels. The stimuli gratings generated by crossing four levels each of spatial orientation. In Experiment 1, subjects made a single stimuli. 2, two responses made, one for component other component. 3, identified either or in any block trials. data confusion matrices, an information-transmission approach was used investigate the-interactions system. results show that although there sensory associations, no interactions decisional level. Performance parity found: significant difference between single- double-judgment paradigms terms transmitted. Overall, suggest is coded jointly level, subsequent processing independent, with dimension drawing upon different attentional resources.
