Abstract
An exploratory study of relationships between selected personal characteristics and telephone dialling performance of 81 subjects was conducted. Personal characteristics included age, education, near-vision abilities, work style, psychomotor skill and short-term memory ability. Dialling performance variables included dialling speed and several types of digit errors. The relationships among the measures were investigated using factor analytic and regression techniques. The results of the study indicated that dialling speed was significantly related to age, memory ability and psychomotor skill. Dialling speed stability was related to memory ability, psychomotor skill and visual ability. Dialling accuracy was related to age, work style and visual ability.
