A speaker can structure a phrase where the information is ordered smoothly with the information being dispersed across the phrase or clumped where the information is concentrated in just certain parts of the phrase. These differences of order in a phrase can affect the receiver’s memory processing and retrieval ability of the information. To identify the effect of different sequences of information on brain’s memory recognition and retrieval ability, 324 participants were tested using an online recognition memory test to evaluate their memory performance. The test consists of study and test phase. 150 words that consists of low-, medium- and high-frequency words were chosen and assigned into clumped and smooth word list. The study phase reveals 75 words, and participants were asked to memorize the words. The test phase shows 150 words, and participants were asked to decide whether they have seen the words before and rate their confidence level. Memory performance was analysed using ROC curves and statistical analysis. The difference in word spreading affects participant’s total memory performance and recollection. Participants with smooth word list have higher memory performance than the participants with clumped word list. Smooth sequence is easier to process by the brain due to less of high informational words being clumped together that minimizes the loss of information when temporary memory failure happens. Implication of this study is to help improve learning process through better delivery of information by the teacher to optimize student’s ability to retain information.

摘要

A speaker can structure a phrase where the information is ordered smoothly with the information being dispersed across the phrase or clumped where the information is concentrated in just certain parts of the phrase. These differences of order in a phrase can affect the receiver’s memory processing and retrieval ability of the information. To identify the effect of different sequences of information on brain’s memory recognition and retrieval ability, 324 participants were tested using an online recognition memory test to evaluate their memory performance. The test consists of study and test phase. 150 words that consists of low-, medium- and high-frequency words were chosen and assigned into clumped and smooth word list. The study phase reveals 75 words, and participants were asked to memorize the words. The test phase shows 150 words, and participants were asked to decide whether they have seen the words before and rate their confidence level. Memory performance was analysed using ROC curves and statistical analysis. The difference in word spreading affects participant’s total memory performance and recollection. Participants with smooth word list have higher memory performance than the participants with clumped word list. Smooth sequence is easier to process by the brain due to less of high informational words being clumped together that minimizes the loss of information when temporary memory failure happens. Implication of this study is to help improve learning process through better delivery of information by the teacher to optimize student’s ability to retain information.
