The Effect Of Word Abbreviation On Decoding Speed And Accuracy, Frances Piccione

Masters Theses

An experiment was conducted to verify the existence and determine the magnitude of the human response latency differential between words and their abbreviations in a decoding task. Forty-eight Naval Officer Candidates learned a set of abbreviations obtained from operational aircraft cockpits. Abbreviations and corresponding words were divided into easy and hard difficulty levels. Subjects responded by saying the correct whole-word for both stimulus types. Response times measured by a voice key revealed a mean of 0.534 seconds for words and 0.662 seconds for abbreviations. An analysis of variance produced significant main effects (p < .05) for stimulus types and difficulty levels; the interaction effect was not significant. Also, t-tests for correlated scores revealed significant differences (p < .05) between difficulty levels within stimulus types.
