Psychomotor Aspects of Mental Disease

Experimental Psychologic Methods Applied in Psychopharmacology

“…Disjunctive lift and jump reaction times (DRTV and DRTA) in response to visual and auditory stimuli were determined according to King (1954) and Ireland (1956). The apparatus consists of two components : first a keyboard equipped with three circular silver electrodes sunk into surface of the table and a panel for delivery of light and sound signals at the far end of the table; second an automatic impulse generator that delivers a t random right and left signals and an electronic computer that drives a recording calculator.…”

Psychomotor Performance of Mental Retardates

“…It demonstrated conclusively that there was a relationship between psychomotor test performance and successful completion of flight training. King (1954) showed a relationship between psychomotor test performance and the rated severity of impairment in a group of mentally ill patients. Weaver (1961) confirmed this finding in part.…”

“…Weaver (1961) confirmed this finding in part. This area is summarised in an excellent review of the literature by King (1969). Weaver and Brooks (1967) have demonstrated that a psychomotor test battery can be used to predict, on an actuarial basis, the probability of release from a mental hospital.…”

“…A second question is also investigated in the present study. The use of the psychomotor test battery in differentiating mental patients into more-sick and less-sick categories has been reported by King (1954), Weaver (1961), and Weaver and Brooks (1967). The relationship between the psychomotor test scores and the rated degree of retardation is studied in the institutionalised group of mental retardates.…”

Relation Between Fine and Gross Psychomotor Movement in Schizophrenia

“…It has also been known for some time, or at least strongly suspected, that defects in motility might also be observed in certain fine psychomotor actions by schizophrenic persons in their performance of such activities as the speed of initiating a response, the tempo of repetitive response, the dextrousness of response, etc. The extensive literature relating to the experimental demonstration of these phenomena has recently been reviewed by King,3,4 …”
