The influence of music on mild driver aggression

Automobile drivers were randomly assigned to either a “music” or “non-music” group. The music group listened to their favorite music, while the non-music group abstained from any music or talk radio, during their entire commute to or from school⧹work. Using a cellular telephone, state measures of driver aggression, time urgency, and stress arousal were obtained during a single commute in low and high congestion conditions. No predictors of mild aggression were found in low congestion. In high congestion, a music X time urgency interaction was found. Mild aggression was lower among those listening to music but only at low levels of time urgency. Results are interpreted in terms of the distractibility and relaxation effects.     

Traffic congestion,driver stress,and driver aggression

Drivers were interviewed over cellular telephones in high‐ and low‐congestion conditions during a single commute. During each interview, state measures of driver stress and driver behaviors were obtained. Behavior responses were subdivided into six categories: aggressive, information seeking, planning, minor self‐destructive, distraction, and relaxation techniques. Both state driver stress and aggression were greater in high‐ than in low‐congestion conditions. No other behavior category differed between low and high congestion. Multiple regressions were calculated to determine the predictors of state driver stress. In low congestion, time urgency predicted state driver stress, while aggression predicted driver stress in high congestion. In both conditions, a trait susceptibility toward viewing driving as generally stressful was predictive of state driver stress levels, which further strengthens the use of the Driving Behaviour Inventory—General as a predictor of “trait” driver stress. Females and males did not differentiate on state stress or any behavior category. Aggr. Behav. 25:409–423, 1999. © 1999 Wiley‐Liss, Inc.     

Effects of music on mood during bench stepping exercise

This study evaluated the effect of music on the mood of women during exercise. 16 middle-aged women, aged 49.9 +/- 7.53 yr., performed 60-min. bench stepping exercise while listening to Japanese traditional folk song, aerobic dance music, or nonmusic. The subjects reported significantly less fatigue with aerobic dance music and Japanese traditional folk song than with nonmusic. Aerobic dance music was associated with significantly more vigor and less confusion than nonmusic.     

Flextime Commuters and Their Driver Stress, Feelings of Time Urgency, and Commute Satisfaction

The purpose of this study was to investigate the effect of a flextime-working environment on driver stress, feelings of time urgency, and commute satisfaction for commuters in a large-city environment. It was hypothesized that, regardless of gender, commuters with flextime would have less driver stress, fewer feelings of time urgency, and more commute satisfaction. The study was conducted using one hundred and twenty-five full-time employed commuters from Atlanta, Georgia, the city with the largest average commute distance in the world. Results showed that the commuters with flextime reported less driver stress and fewer feelings of time urgency than those without flextime. Significant differences were not found for commute satisfaction. Gender did not appear to be a significant factor in determining driver stress, time urgency, or commute satisfaction.     

The Impact of Commuter Stress on Workplace Aggression

Immediately following their regular commute to work, participants completed questionnaires regarding state driver stress and anger during that commute. Then, immediately following completion of that work day, they completed a state version of the Workplace Aggression Scale. As state driver stress increased, the frequency of both expressed hostility and obstructionism increased (independently) during that work day, but only among male employees. In contrast, overt aggression during that work day was greatest among males who were higher in physical aggressiveness as a general trait characteristic. The present study highlights the interactive nature of traffic and workplace environments, in that negative experiences in the traffic environment may spill over for some individuals to influence nondriving events.     

The fast and the female: Gender differences in wellbeing and wage consequences of commute impedance

At equal distance, the impedance created by traffic congestion strongly affects the duration of commute. Extant literature indicates that commute impedance negatively affects wellbeing, distinctly from the distance and the duration of commute. These negative effects are reported to be larger for women. Consequently, workers, especially females, must be willing to accept lower wages if reaching the job location entails fewer traffic congestions and accommodates a speedier commute. Using the Canadian General Social Survey of 2015 and the Census of 2016, the present paper assesses the wellbeing and wage consequences of commute impedance on men and women who drive to work. The study first demonstrates that the negative impact of commute impedance on wellbeing is greater for women. Second, consistent with the greater negative effect of traffic congestion on their wellbeing, women appear to pay a price off their wages, in order to avoid commute impedance. The policy implications are discussed.     

Adaptations in driver deceleration behaviour with automatic incident detection: A naturalistic driving study

Traffic congestion and crash rates can be reduced by introducing variable speed limits (VSLs) and automatic incident detection (AID) systems. Previous findings based on loop detector measurements have revealed that drivers reduce their speeds while approaching traffic congestion when the AID system is active. Notwithstanding these behavioural effects, most microscopic traffic flow models assessing the impact of VSLs do not describe driver response accurately.This study analyses the main factors that influence driver deceleration behaviour while approaching traffic congestion with and without VSLs. The Dutch VSL database was linked to the driver behaviour data collected in the UDRIVE naturalistic driving study. Driver engagement in secondary tasks and glance behaviour were extracted from the video data. Linear mixed-effects models predicting the characteristics of deceleration events were estimated.The results show that the maximum deceleration is high when approaching a slower leader, when driving at high speeds and short distance headways, and close to the beginning of traffic congestion. The minimum time headway is short when driving at high speeds and changing lanes. Certain drivers showed higher decelerations and shorter time headways than others. Controlled for these main factors, smaller maximum decelerations were found when the VSLs were present and visible, and when the gantries were within close proximity. These factors could be incorporated into microscopic traffic simulations to evaluate the impact of AID systems on traffic congestion more realistically. Further research is needed to clarify the link between engagement in secondary tasks, glance behaviour and deceleration behaviour.     

Developing identities and attitudes in musicians and classroom music teachers

Background. The Western classical training of many secondary music specialist teachers may be inappropriate for the demands of the contemporary secondary school classroom, leading to a conflict between their self‐concepts as ‘musicians’ and as ‘teachers’. Aims. To undertake a short‐term longitudinal comparison of the developing identities and the attitudes of a group of intending specialist secondary music teachers, during the transition into their first teaching post, with a group of music students from university and conservatory backgrounds. Sample. Twenty‐nine trainee music teachers completed Phases 1 and 2 of the study during their final weeks of training and during the second term of their teaching career, and a comparison group of 29 final‐year undergraduate music students did so in the first and last terms of their final year. Method. A specially devised composite Musical Careers Questionnaire gathered information in both phases about self‐efficacy in music and in teaching, identification with professional groups in these two domains, and attitudes towards important skills for musicians and teachers. Results. A series of ANOVAs comparing the student groups' scores in each of the two phases revealed no significant main effects or interactions for either of the self‐efficacy measures, a significant group effect for professional group identification, and some changes in the attitude measures. Conclusion. Although participants' views of their own general effectiveness as teachers and as musicians changed very little over the period of the study, their attitudes towards music teaching and perceptions of the skills required showed some changes.     

Driving-induced stress in urban college students

Urban college student commuters (N = 407) were surveyed about their experiences with stress induced by driving. Of the participants 23.6% reported becoming angry at another driver more than once per day. They rated stress from other drivers as equal to the stress experienced during a college examination but gave slightly lower ratings to traffic congestion, road construction, and finding a parking place as sources of stress. Slow drivers, a child not restrained, and a vehicle following too closely were the highest rated annoying situations. Of participants, 21.6% had reported another driver to the police; nearly 22% said they carried a weapon for protection from other drivers (5.4% said a gun). Men were more than twice as likely as women to carry a weapon and three times as likely to carry a gun. Of the total sample, 19.1% feared being shot by another driver. Most participants (75.8%) said drivers were more aggressive and dangerous than they were five years ago.     

Distraction,Control, and Dental Stress1

This study examined the efficacy of external distraction as a coping strategy. Thirty-eight dental patients were randomly assigned to one of three groups: incidental music during the dental procedure, music coupled with suggestions that music would help reduce stress, or a no-treatment control group. Patients in both music groups reported experiencing less stress (i.e., less pain. less discomfort, more control) than patients in the no-treatment group. Patient ratings made by dentists, blind to condition, provided converging evidence for the therapeutic effect of distraction. Thus, distracting music was found to be effective in reducing stress and increasing perceptions of control. The relative ease and simplicity of implementing external distraction compared to manipulating actual control in a medical setting may make this manipulation attractive to professionals involved with individuals experiencing stress.     

Music interferes with learning from television during infancy

Infants are frequently exposed to music during daily activities, including free play, and while viewing infant‐directed videotapes that contain instrumental music soundtracks. In Experiment 1, an instrumental music soundtrack was played during a live or televised demonstration to examine its effects on deferred imitation by 6‐, 12‐, and 18‐month‐old infants. Transfer of information was indexed via deferred imitation of the target actions following a 24‐h delay. For half the infants, the music context was also reinstated at the time of test. Performance by experimental groups was compared to that of a baseline control group that participated in the test session without prior exposure to the demonstration. Imitation performance was above baseline for the live groups but not for the video groups regardless of age or the music context at test. In Experiment 2, we added matched sound effects to the video demonstration and infants performed above baseline. We conclude that the music track creates additional cognitive load, disrupts selective attention to the target actions and inhibits transfer of learning from television of the imitation task. Music may impair an infant's ability to translate information from a two‐dimensional to three‐dimensional world even if the auditory context remains the same.

SHALL WE DANCE? MUSIC AS A PORT OF ENTRANCE TO MATERNAL–INFANT INTERSUBJECTIVITY IN A CONTEXT OF POSTNATAL DEPRESSION

The present study introduces the concept of a mother–infant group therapy that makes use of music, singing, and moving to establish maternal–infant intersubjectivity. It was conducted in a residential mother–baby unit for mothers with postnatal depression and their infants over a 5‐week period. Maternal–infant intersubjectivity of four dyads in relation to the group dynamics were microanalyzed for Sessions 1 and 5. We made within‐session (i.e., beginning–middle–end) and between‐session (Session 1 vs. Session 5) comparisons for the number of intersubjectivity moments (ISMs), total time of intersubjectivity (IST), and the mean duration of ISMs on a dyadic (i.e., own mother/infant involved) and a nondyadic level (i.e., own mother/infant not involved). In addition, three ISM levels (degree of group contribution) were distinguished. The results indicated a significant increase of ISMs/IST from Session 1 to Session 5. Within‐session analyses showed that ISMs/IST significantly decreased through Session 1 and remained stable throughout Session 5. Intersubjectivity occurred mainly on ISM Level 1 during Session 1 and on ISM Level 3 during Session 5, suggesting increased dyadic autonomy and self‐efficacy. The results are discussed in relation to the musical characteristics of mother–infant dyads, music improvisation techniques, group processes, and intersubjective development.     

Sharing My Music with You: The Musical Presentation as a Tool for Exploring,Examining and Enhancing Self‐Awareness in a Group Setting

Musical presentation (MP) is a diagnostic and therapeutic music therapy tool which focuses on the participant's emotional exploration and awareness‐insight development. Using this tool people present themselves through music of their choice and subsequently receive feedback from their peers. This study investigates MP as a tool for enhancing self‐awareness in the context of a voluntary activity that was integrated in courses for undergraduate students in order to demonstrate its possible uses. Open‐ended in‐depth interviews with 15 MP presenters and focus‐group interviews with 41 MP peers who listened to the presentations were conducted. The Johari Window, which is a cognitive psychological model used to help people better understand their interpersonal communication and relationships, served as a conceptual framework for this study. Qualitative analysis of the data showed that presenters' self‐awareness was enhanced through the use of both music and words. As an accessible and creative tool, the MP can be used as a way for people in both therapeutic and non‐therapeutic settings to present themselves via their music to a group and increase their self‐awareness.     

A performance analysis of In-Car Music engagement as an indication of driver distraction and risk

Drivers engage in a host of driving-unrelated tasks while on the road. They listen to music, sing-along, and accompany songs by pounding-out drum-kicks and syncopated rhythms on the steering wheel. However, there is controversy over in-cabin music: Does background music facilitate driver performance via increased arousal leading to more focused concentration, or cause distraction placing drivers at greater risk. In an effort to shed light on the debate, the current study evaluated music engagement by employing Music Performance Analyses with audio recordings from three simulated driving conditions. The results indicate that as the perceptual demands of the primary driving task increased, the secondary music activity was hampered, and subsequently sub-optimal vocal and percussive performances were demonstrated consisting of intonation errors, rhythmic inaccuracy, lack of synchrony, inconsistent and unstable temporal flow, neglect of text, and lyric replacement. The findings seem to point out that drivers allocate greater reserves to music than previously considered, and as drivers do not withdraw altogether from music engagement under high-demand driving conditions, driving may be under-resourced. Exploring active music engagement while driving might assist traffic safety researchers in decoding the effects of In-Car Music on driver behavior.     

Maltreated Children's Memory of Stressful Removals from Their Biological Parents

The effects of stress on memory were examined through a study of 33 3 to 12‐year‐old maltreated children removed from their biological parents by the Child Protective Services because of an emergency (acute) or normal (planned) care order. Children's stress levels were rated by a researcher present during the removal and children's memory of the removal investigated at a later time. The type of removal significantly predicted children's level of stress. ‘Acute removal’ children remembered more from high‐stress phases of the removal than the ‘planned removal’ children. All children had more accurate memories of the low‐stress phases. Details remembered were rated as central or peripheral; more central information was recalled than peripheral information. The ‘acute removal’ children recalled more peripheral information from the high‐stress phases of the removal than the low‐stress phases, a difference, which was not present for the ‘planned removal’ children.

Does traffic congestion increase driver aggression?

In his recent article about aggressive driving, David Shinar proposed that the classical frustration-aggression hypothesis (Dollard, J., Doob, L., Miller, N., Mowrer, O. & Sears, R. (1939). Frustration and aggression. New Haven, CN: Yale University Press) provides a useful tool for understanding driver aggression (Shinar, D. (1998). Aggressive driving: the contribution of the drivers and situation. Transportation Research Part F, 1, 137–160). According to Shinar's (1998) application of the frustration–aggression hypothesis, driver aggression is caused by frustration because of traffic congestion and delays. In the present study, the relationships between exposure to congestion (rush-hour driving) and aggressive violations (DBQ) were investigated in Great Britain, Finland and the Netherlands. Partial correlations showed that the frequency of rush-hour driving did not correlate statistically significantly with driver aggression. Correlations between driving during rush-hour and aggression did not differ in magnitude from those between driving on country roads and aggressive violations. In addition, correlations between exposure to congestion and aggressive violations in countries with large number of vehicles per road kilometre (UK, Netherlands) were not higher than those in a sparsely populated country (Finland). These results from three countries suggest that congestion does not increase driver aggression as directly as suggested by Shinar (1998).     

How do location and control over the music influence listeners’ responses?

This study uses Mehrabian and Russell's ( 1974 ) Pleasure‐Arousal‐Dominance (PAD) model to consider how responses to both the music heard and overall in‐situ listening experience are influenced by the listener's degree of control over music selected for a particular listening episode and the location in which the listening takes place. Following recruitment via campus advertisements and a university research participation program, 216 individuals completed a background questionnaire and music listening task in a 3 (location) × 2 (experimenter‐ or participant‐selected music) design. After the listening task, participants completed a short questionnaire concerning the music they heard and the overall in‐situ listening experience. Results demonstrated that there was a positive relationship between control and liking for the music and episode, whether the former was considered in terms of: (1) whether the music was self‐selected or experimenter‐selected or (2) overt ratings of perceived control. Furthermore, the location and liking for the music were related to people's judgments of their enjoyment of the overall experience. This research indicates that the PAD model is a useful framework for understanding everyday music listening and supports the contention that, in a musical context, dominance may be operationalized as control over the music.     

Stress and immune system function in a newspaper's newsroom

Data were collected on 10 newswriters in a newspaper's newsroom. These included self-reported stress ratings and saliva samples for secretary immunoglobulin A (IgA) analysis. The stress ratings and saliva samples were taken initially and after three 30-min. periods. The first time period was a baseline measure and involved the workers engaging in their usual tasks. At Time 2 music was presented for 30 min. while workers engaged in their normal activities. At Time 3 workers resumed their normal duties. Findings showed an increase in IgA that was not statistically significant, a reduction in stress during the music period that was statistically significant, and a statistically significant negative correlation between stress and IgA.

Interpersonal synchrony increases prosocial behavior in infants

Adults who move together to a shared musical beat synchronously as opposed to asynchronously are subsequently more likely to display prosocial behaviors toward each other. The development of musical behaviors during infancy has been described previously, but the social implications of such behaviors in infancy have been little studied. In Experiment 1, each of 48 14‐month‐old infants was held by an assistant and gently bounced to music while facing the experimenter, who bounced either in‐synchrony or out‐of‐synchrony with the way the infant was bounced. The infants were then placed in a situation in which they had the opportunity to help the experimenter by handing objects to her that she had ‘accidently’ dropped. We found that 14‐month‐old infants were more likely to engage in altruistic behavior and help the experimenter after having been bounced to music in synchrony with her, compared to infants who were bounced to music asynchronously with her. The results of Experiment 2, using anti‐phase bouncing, suggest that this is due to the contingency of the synchronous movements as opposed to movement symmetry. These findings support the hypothesis that interpersonal motor synchrony might be one key component of musical engagement that encourages social bonds among group members, and suggest that this motor synchrony to music may promote the very early development of altruistic behavior.
