Analysis of the cognitive-motor processes involved in shorthand writing
A review of the experimental findings an performance measures in typewriting and the failures of subjects to-locate the positions of interpolated clicks correctly in auditorily presented texts, lead to the formulation of the theoretical framework of the investigation. Four experiments investigated the accuracy with which shorthand and non-shorthand writers located the positions of clicks, interpolated at specific points in relation to the boundaries of semantic/ syntactic units in dictated texts of four degrees of decreasing grammatical structure. The direction of click mislocation was affected by the input conditions of the dictation. The direction and extent of click mislocations did not support the linguistic hypothesis that verbal input is perceived in semantic/syntactic structures which resist interruption from the occurrence of a click.A contact pencil is described which was used to measure the durations of latencies (reaction times), inter-response times and motor responses. The difficulties of interpreting such measures are discussed.Five experiments. investigated the accuracy and speed of responding to clicks to establish whether mislocations occurred as a result of memory load caused by: the overall structure of texts; the acoustic, semantic or response characteristics of words preceding or following the click; the typo of response used to indicate the position of the click and its relationship with the preceding and following words;the rate of presentation of input and sequence length; and attentional control when the click occurred. The number of click mislocations, and the speed of responding to clicks, tended to be greater when the words preceding and following them had semantic, rather then response, characteristics in common. Attontional control is required during the initial stages of response output. Processing operations to translate stimuli into responses are carried, out serially.Some theoretical issues and applications of the work are discussed.

Abstract
A review of the experimental findings an performance measures in typewriting and the failures of subjects to-locate the positions of interpolated clicks correctly in auditorily presented texts, lead to the formulation of the theoretical framework of the investigation. Four experiments investigated the accuracy with which shorthand and non-shorthand writers located the positions of clicks, interpolated at specific points in relation to the boundaries of semantic/ syntactic units in dictated texts of four degrees of decreasing grammatical structure. The direction of click mislocation was affected by the input conditions of the dictation. The direction and extent of click mislocations did not support the linguistic hypothesis that verbal input is perceived in semantic/syntactic structures which resist interruption from the occurrence of a click.A contact pencil is described which was used to measure the durations of latencies (reaction times), inter-response times and motor responses. The difficulties of interpreting such measures are discussed.Five experiments. investigated the accuracy and speed of responding to clicks to establish whether mislocations occurred as a result of memory load caused by: the overall structure of texts; the acoustic, semantic or response characteristics of words preceding or following the click; the typo of response used to indicate the position of the click and its relationship with the preceding and following words;the rate of presentation of input and sequence length; and attentional control when the click occurred. The number of click mislocations, and the speed of responding to clicks, tended to be greater when the words preceding and following them had semantic, rather then response, characteristics in common. Attontional control is required during the initial stages of response output. Processing operations to translate stimuli into responses are carried, out serially.Some theoretical issues and applications of the work are discussed.
