WASHINGTON - TYPING numbers on a phone keypad that correspond to the letters in a word like 'love' can activate the meaning of the word in our minds and make us feel good, a study published on Wednesday says.
German psychological scientist Sascha Topolinski conducted a series of experiments to determine this, including one where he gave a cell phone with stickers obscuring the letters on the keypad to a group of several dozen professionals and asked them to type number sequences that correspond to words.
The participants in the experiment were told the study was looking at the ergonomics of different number sequences on phone keypads. Ergonomics is the science of fitting workplace environments and tools to users.
Some of the words they typed without realising were positive, like 54323 for 'Liebe,' which in English would be 5683 for 'love,' or 787263 for 'Strand,' which means 'beach.' The study participants also typed 'negative' number sequences on the keypad - things like 7245346 for 'Schleim,' which is close to its English equivalent, 'slime,' or 35363 for 'Elend,' or misery.
After they had tapped out the numbers, participants were asked to rate on a scale of zero to 10 how pleasant an experience they had doing it.
'Participants preferred dialing numbers implying positive words over numbers implying negative words,' Mr Topolinski wrote in the study. 'This finding suggests that the affective meaning of emotional words can be induced by merely dialing numbers that imply those words via key concordance,' the study says. -- AFP
