In the modern time, people are required to deal with numerous messages in the working time very often. The message processing usually includes memorization and transformation in order to simplify the present of information. Thereby, design of message presentation has been a critical factor of improving working performance. Over the experiment, we acquired and recorded the data of working performance and subjects' brain wave during the task operating. This research is going to discuss the effects of short-term memory load and verbal transformation on working performance and EEG response. Working performance in this experiment consisted of finish time and error number. EEG response included θ rhythm and α signal. The results were analyzed with SPSS and showed that: With increased memory load, both finish time and error number significantly increased. Verbal transformation significantly affected finish time and error number. ETR caused the longest finish time, and TR caused the largest error number. Frontal-θ?rhythm increased in strength with the difficulties of memorization and transformation. Occipital-α ?signal decreased in strength while the amount of characters remembered increased, and showed the strongest power for TR. The left hemisphere was more functional than the right side during verbal memorization and transformation. ? 2011 Taylor & Francis Group.
