Eye and arm movements to single and double-step target displacements were studied to investigate whether or not the motor systems of the eye and arm share common command signals from the internal representation, which specify a) when a movement is initiated and b) the end position of a movement. The correlation between the time of onset of eye and arm… (More)
The motor programming of fast goal-directed arm movements was studied in a tracking task. A target jumped once or twice randomly to the left or right direction with an interstimulus interval (ISI) in a range between 50 and 125 msec. Double step stimuli were either two steps in the same direction (C-trial) or in opposite direction (R-trial). Tracking results… (More)
Some simple REDUCE facilities are presented for pretty-printing quotients, formal derivatives and subscripted variables. The package, an extension of previously published possibilities, is completely written in RLisp and can be considered as an addition to the output repertoire of the Algebraic Mode.
New REDUCE packages often require additions to the REDUCE syntax. In this note we present a detailed description of REDUCE parsing tools and step-by-step instructions of adding new statements.
