The Effect Of Word Abbreviation On Decoding Speed And Accuracy, Frances Piccione
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.
The Effects Of Self-Evaluation Procedures On The Numbers And Accuracy Of Alphabet Letter Writing Behavior Of Preschool Children, Kevin R. Coleman
The Effects Of Self-Evaluation Procedures On The Numbers And Accuracy Of Alphabet Letter Writing Behavior Of Preschool Children, Kevin R. Coleman
Masters Theses
This study assessed the effects of self-evaluation procedures on the rate and accuracy of alphabet letter writing. Three preschoolers served as subjects. During Phase I, students were given instructions, and the experimenter modeled accurate letter writing. During Phase II, instructions and modeling were again presented. Additionally, the students were given a rule statement that instructed them to use a stamper and a stamp pad to stamp their paper after first writing each of a row of four letters. The results indicated that the introduction of self-evaluation procedures was associated with immediate increases in frequency of attempts, but a decrease in …
