“…That component which reflects the time course of events within the central processes (DT) was greater in both depressive samples than in the normal control sample. This provides reasonable evidence for inferring some impairment within the central information-processing mechanism (Weiss, 1965 ; Welford, I 968 ;Danev et al, 1971). Furthermore, a significant elevation of D T in the psychotic relative to the neurotic depressive sample suggests that the magnitude of this postulated central impairment is greater in psychotic than in neurotic depressive patients.…”

“…Employing this experimental procedure, the first timer measured the time course of events from stimulus presentation to decision to respond. This component of response latency, which may-be termed decision time (DT), has been suggested to provide an accurate index of the efficiency of the central information-processing mechanism (Weiss, 1965 ;Welford, 1968;Danev et al, 1971).…”

“…This component of response latency, which may be termed movement time (MT), can be considered to reflect peripheral psychomotor speed, a function of both the distance from response initiation to completion, and of the magnitude of the muscular response (Fitts, 1954;Crossman, 1957;Welford, 1968). Again it is worth stating that in view of the suggested independence of DT and M T (Henry, 1961;Weiss, 1965;Welford, 1968;Danev et al, 1971), the response latency reflecting peripheral psychomotor speed must be considered to do so independently of the ability of the central information-processing mechanism to deal with incoming information. All subjects were tested in a dimly lit, sound-attenuated room, with recording equipment in an adjacent room.…”

“…Psychomotor retardation is a frequently observed feature of depressive states (Hamilton, 1967;Colbert & Harrow, 1967;Costello, 1970). Slowing of gross psychomotor speed (Shakow & Huston, 1936; Wulfeck, I941 ; Brower & Oppenheim, 1951 ; Beck et nl., 1962) and simple reaction time (RT) (Huston & Senf, 1952;Hall & Stride, 1954;Court, 1968) (Henry, 1961;Weiss, 1965;Welford, 1968;Danev et al, 1971) that there is little or no relationship between central and peripheral components of RT measures. The independent measurement of peripheral and central components of RT may therefore provide added information on the nature and magnitude of psychomotor slowing in depressive states.…”

An experiment was performed in which two components of response latency, decision time (DT) and movement time (MT), were measured in two relatively homogeneous samples of neurotic and psychotic depressive patients, together with a normal control group. It was found that whereas both DT and MT were significantly longer in the depressive samples than in the control sample, only DT was significantly longer in the psychotic than in the neurotic depressive sample. Thus while both DT and MT were elevated among the depressive samples relative to the control sample, only DT was further sensitive to clinical variations within the depressive state. DT was found to increase directly with depressive severity among an undifferentiated sample of acute depressives, which on further analysis proved to hold for the neurotic depressive sample only. MT was found to increase directly with age among the psychotic depressive sample. No other age influences were found on response latencies of depressive patients. These results are discussed in terms of a postulated impairment of the central information-processing mechanisms, as an explanation of psychomotor slowing among depressive patients.

“…For convenience, the first of these intervals will be called the decision time (DT), and the second, movement time (MT). DT and MT are analogous, respectively, to the RT (reaction time) and MT (movement time) measured in an experiment on movement accuracy reported by Fitts and Peterson (1964), but they are not analogous, it may be noted, to the reaction and motor times as measured in an experiment by Danev, deWinter, and Wartna (1971). The sum of DT and MT constitutes total time (TT).…”

Nine subjects, 5 of whom claimed absolute pitch (AP) ability (4 from childhood, 1 by self‐training) were given a pitch judgment task in which they had to strike notes on the piano as rapidly as possible to match randomized tape‐recorded piano notes. Stimulus set sizes were 64, 16, or 4 consecutive semitones, or 7 diatonic notes of a designated octave. A control task involved motor movements to notes announced in advance, with the effect that set size was 1. Accuracy, measured on the basis of deviations of responses from targets, significantly differentiated AP from NAP (non‐AP) subjects at all set sizes except the control task. For both groups, accuracy increased as set size decreased. Decision times, measured as that part of total response time before a movement to the response note began, decreased as set size decreased, but did not differentiate AP and NAP subjects. The performance of the trained AP subject was not distinguishable from that of the remaining AP subjects either in accuracy or decision time. Results are discussed in terms of a two‐factor theory of AP ability whereby NAP subjects use only relative tone height as the basis of judgment but AP subjects also use standards of tone chroma stored in long‐term memory. The abnormally high channel capacities and rates of information gain for AP subjects are interpreted on the basis of transmission of information in two channels, whereas NAP subjects transmit information in only one channel.
