Abstrakt: A test movie consisting of 13 different silent movie scenes, each 10s in duration, was developed to test in patients the elementary abilities, perception and recognition of mimic and gestural expression. Each scene was subjected to 10 (2×5) verbal or non-verbal multiple-choice tests. Quantitative analysis of normal control group results is described. All sub-tests were very easy for normals and resulted in error scores below 5%. Thus the test is not designed to differentiate within a group of normal subjects but to characterize a pathological reduction in mimic, gesture and person recognition in schizophrenic and brain-lesioned patients. By measuring the dependency of correct recognition of the different movie scenes on the inspection duration, it was shown that the projection time of 10s applied in the full test led to a fairly high amount of informational redundancy. This was intentional so that stimulus material could be well perceived and recognized even by patients with somewhat fluctuating attentiveness. [ABSTRACT FROM AUTHOR]
