Previous studies have offered contrasting evidence, and it has been recently shown that listening to music negatively affected concurrent mental processing in the elderly but not in young adults. To further investigate this matter, the effect of listening to music vs.
Heart rate and diastolic and systolic blood pressure were measured during an explicit face study session that was followed by a memory test. The results indicated that more efficient and faster recall of faces occurred under conditions of silence or when participants were listening to emotionally touching music.
Whereas auditory background e. It is hypothesized that touching music is able to modify the visual perception of faces by binding facial properties with auditory and emotionally charged information musicwhich may therefore result in deeper memory encoding.
A total of 54 non-musicians listened to joyful or emotionally touching music, rain sounds, or silence while studying hundreds of faces Heart rate and diastolic and systolic blood pressure were measured during face encoding Except for emotionally touching music, auditory background interfered with memory recall Touching music is able to bind visual properties with emotionally charged information musicwhich results in enhanced memory The effects of listening to background music on concurrent mental processing are controversial.
Overall, although listening to music appears to have positive effects on emotions and especially on motor behavior such as athletic performanceit appears to interfere with reading and memory tasks see ref.
In automobile driving, listening to music appears to alleviate driver stress and reduce aggression; however, in conditions that require attention and mental concentration, driving performance is impaired 2.
Two perspectives have been proposed to account for the effects of background music on cognitive processes: When concurrent tasks compete for limited resources and their combined demands exceed the available capacity, capacity interference occurs.
Only a portion of the task information is processed and therefore performance deteriorates. The interference caused by task-irrelevant information for example, listening to music also depends on the complexity of the information that is being processed and on the workload that is required to process task-relevant information.
Indeed, increasingly complex musical distractions may result in decreased cognitive performance 4. In contrast, the Arousal-Mood hypothesis posits that listening to music affects task performance by positively influencing arousal and mood 5which is a phenomenon that is also known as the Mozart effect 6.
This hypothesis has been supported by several studies that have investigated the effect of listening to background music on the performance of cognitive tasks.
For example, improvements in verbal memory encoding 7autobiographical memory in Alzheimer patients 8verbal and visual processing speed 9arithmetic skill 10reading 11and second language learning 12 have been documented. Conversely, reduced performance in the presence of background music has also been demonstrated for example, see ref.
Listening to background music vs. Recently, Bottiroli et al. In contrast, Reaves et al. In their study, both young and old adults listened to music or to silence while simultaneously studying face-name pairs.
Therefore, although music may help to relax individuals who are trying to concentrate, it appears that it does not help them to remember what they are focusing on new informationespecially as they age.
Overall, the data are conflicting, although it appears that listening to background music most interferes with tasks that involve memory, especially for verbal items. To the best of our knowledge, the effect of listening to music on the ability to remember nonverbal or linguistic items has not been previously investigated.
To further investigate this matter, in this study, the ability to remember human faces was evaluated in the context of different types of acoustic background, including silence as a non-interfering controlthe sounds of rain and storms generally thought to have a relaxing effect 2829and occidental music of different emotional content and style.
A previous study 30 compared listening to silence with listening to music or rain during a backward digit span task and found no effect of auditory background on performance. To provide information about the effect of background noise on alertness and arousal levels, as well as possible autonomic correlates of emotional responses, heart rate and systolic and diastolic blood pressure were measured during the first part of the experiment study phase.
In this session, unknown male and female faces were presented to participants in an explicit memory encoding situation. The study session was followed by a memory test that consisted of evaluating the recognition of previously viewed faces that were randomly interspersed with new faces, under conditions of silence.
Hit and error percentages were quantified as functions of the experimental conditions listening to emotionally touching music, to joyful music, to the sound of rain, to silence. The aim of the present study was to determine the autonomic and cognitive correlates of non-verbal memory processing as a function of the nature of an auditory background or the lack of it, i.in and around the cryogenic bolometer and the evaluation of its effect on the gamma background level.
The paper is organized as follows: Section 2 describes the experimental details, while data. All three studies found those effects to be uncertain (the analyses of effects on those aged 21 and older in Ludwig and Cook, ; the Brady Act effect in La Valle, ; and the private-seller background check effect in Lott, ).
Unlike the studies found in the review of literature on the effects of background television on cognitive tasks, this study focuses on how different types of music may distract or impair the student’s concentration during a reading comprehension task.
