     Studying for an exam while listening to music is not smart, because background music can injure

your ability to perform memory tasks, new research has found.

     Study participants were asked to recall a list of eight consonants (辅音字母) in the order they

were presented. They did this while in five different sound environments: quiet surroundings; music

they liked music they disliked; changing state; and steady state.

     The participants recall ability was poorest when listening to music, regardless of whether

they liked or disliked it, and in changing-state conditions. The most accurate recall occurred

     when participants performed the task in steady-state environments, according to the study

published online in the journal Applied Cognitive Psychology.

     The poorer performance of the music and changing-state sounds are due to the audible (听得

见的) change within those environments. This hurts the ability to recall the order of items, via retelling,

within the presented list, explained lead researcher Nick Perham, a lecturer in the School of Psychology

at the University of Wales Institute in Cardiff, in a news release from the journal's publisher.

      "Mental arithmetic (算术) also requires the ability to memorize order information in the short-term

via retelling, and may be similarly affected by their performance in the presence of changing-state,

background environments," he added.
