English to Russian Social Sciences Psychology

Can someone help me with the Russian terms for “successive processing" and "simultaneous processing”? The mental processes are meant. The meanings are clear, the definitions can be found on the internet, e.g., here: http://www.gmu.edu/departments/ccd/instructions_parteach.htm... , but I don’t know how these terms would sound correctly in Russian, especially the word “processing” as a mental process.

Context:
XXX’s performance reflects an above average ability to process and organize oral information in sequential order (Successive Processing). His performance on tasks requiring the integration of separate visual-spatial stimuli to form a single, whole product also fell within the average limits (Simultaneous Processing).

Thank you for your help
