The purpose of this study was to examine the reliability and validity of a Japanese short form of the Swanson Cognitive Processing Test, which assesses capacity of working memory. Test-retest reliability was acceptable (r = .76). Concurrent validity was suggested through comparison of scores on the Reading Span Task (r = .55). Means on the Japanese short form were comparable with means for the 3 subtests for the older group and 2 subtests for the younger group. With the exception of the Auditory Digit Sequence, results suggested that both the Japanese short form and the initial Swanson Cognitive Processing Test measured comparably the working memory in the two samples of children.

In this preliminary observation, a group of seven mentally and physically handicapped persons of chronological ages ranging from 15.4 yr. to 26.8 yr. experienced 15 sec. of physical rocking. For the further analysis, the poststimulus periods were classified into either those when the subjects' spontaneous head, mouth, and body movements had increased from the prestimulus period or those decreased. The median heart rates recorded in the poststimulus period were not significantly different from those in the prestimulus period on trials on which there was an observable increase in the rates of spontaneous head, mouth, and body movements; however, the median heart rates decreased during those trials on which a decrease in the rates of the movements occurred. Since it is said that rocking heightens arousal of persons with mental and physical handicaps, it is suggested that spontaneously emitted, aimless head, mouth, and body movements attributed to low arousal were reduced by heightened arousal rather than by a decline in participants' activities.
