Holding a guitar case can increase your success with women… if you’re attractive (and live in France)

I came across a fun little study published on the Psychology of Music. The experimenters designed a simple experiment to test whether music plays in role in sexual selection. To be honest, I am not sure if that was what they actually tested but I’ll let you decide on that. It seems that what they tested was whether holding a guitar case increases women’s receptivity to a courtship solicitation – if you are attractive, male and live in France. The participants were 300 young females with an estimated age between 18 and 22 years, who were walking alone in several shopping streets of a medium-sized city in France. The experiment was conducted on a sunny Saturday afternoon at the beginning of the summer period. A 20-year-old man, previously evaluated as having a high level of physical attractiveness, acted as confederate.

The participants were selected following a random assignment in which the confederate was instructed to approach the first young woman in the age group (18–22 years) who appeared alone on the pedestrian walkway. He was instructed not to select a participant according to her physical attractiveness, the way she was dressed, her height, etc. He was instructed to wait until a young woman between approximately 18 and 22 years of age passed by him in the street, and then to approach her… The confederate was instructed to approach the young women with a smile and to say, “Hello. My name’s Antoine. I just want to say that I think you’re really pretty. I have to go to work this afternoon, and I was wondering if you would give me your phone number. I’ll phone you later and we can have a drink together someplace.” According to the experimental conditions, the confederate held in his hands a black acoustic guitar case (guitar case condition), a large black sports bag (sports bag control condition), or nothing (no bag control condition). After testing 10 women in one condition, the confederate was instructed to move to another area and to select a new experimental condition according to a random distribution.

The confederate talked to 300 women in one afternoon.. Impressive. The results? In the guitar case condition, 31% (!) of the women gave their phone number to the confederate , compared to 9% in the sports bag condition and 14% in the no bag control condition. It seems that holding a guitar case is an effective strategy if you’re attractive. Holding a sports bag seems to have the opposite effect. There are many problems with this study which the authors recognise. First of all, they only used one confederate and his physical attractiveness was high. He was voted as the most good looking guy among a list of others in a previous study. As a result, it is difficult to generalise the effects to other male confederates with various attractiveness levels. It’d be interesting to see if holding a guitar case would increase women’s receptivity to a courtship solicitation by an average looking male. Also, only one instrument was manipulated in this study. Could the effect be limited to the guitar?


Ode To The Brain

The Symphony of Science is a musical project of John D Boswell, designed to deliver scientific knowledge and philosophy in musical form. The project owes its existence in large measure to the classic PBS Series Cosmos, by Carl Sagan, Ann Druyan, and Steve Soter, as well as all the other featured figures and visuals. Continuation of the videos relies on generous support from fans and followers.

Do Strong Right-Handers Prefer Popular Music?

07/08/2011 2 comments

Why do some people like popular music while others prefer less popular genres? A new study published on the journal Psychology of Music proposes a possible explanation for this, handedness. After examining the musical preferences and the handedness scores of 92 undergraduate students, S.D. Christman identified that the strength of handedness is an important factor in individual differences in musical preferences.

More specifically, strong right-handers compared to mixed-handers reported significantly decreased liking of unpopular music genres and marginally increased liking of popular genres. These differences do not appear to reflect differences in musical training or experience.  According to the author of the study handedness is associated with differences in cognitive flexibility. Previous studies suggest that strong right-handedness is associated with decreased interaction between the left and right cerebral hemispheres, which in turn is associated with decreased cognitive flexibility across various domains. The author concludes:

A number of studies report differences between conservatives and liberals in musical preferences (e.g., Glasgow & Cartier, 1985; North & Hargreaves, 2007). For example, Glashow and Cartier (1985) reported that conservatives prefer music that is safe and familiar, presumably reflecting preference for popular, not unpopular, genres. Given evidence that strong right-handedness is associated with increased conservative attitudes (Christman, 2008), this suggests a possible three-way connection between strong right-handedness, conservative views, and a lack of open-earedness. Accordingly, future research on individual differences in musical preferences would be well advised to include strength of handedness as a variable.

Finally, in case you’re curious, here are some of the genres included in each category: (a) popular: modern rock, classic rock, heavy metal, alternative rock, modern pop, 80s pop, R&B, Rap, Hip-hop, country, (b) unpopular: soul, funk, jazz, blues, folk, avant-garde, world, electronica, reggae, ambient, house. The categorisation of popular and unpopular genres was based on record sales (conventional music was defined as popular genres with high numbers of sales, while unconventional music was defined as less popular genres with lower numbers of sales). Even though the proposed idea is interesting, handedness is probably only one of the factors that might explain individual differences in musical preference. For a different approach see a recently published study by Chamorro-Premuzic et al. (2011) who found that individual differences in music consumption are predicted by uses of music and age rather than emotional intelligence, neuroticism, extraversion or openness.

Songs sound less sad when you’re older

22/06/2011 1 comment

Music is a powerful tool of expressing and inducing emotions. Lima and colleagues aimed at investigating whether and how emotion recognition in music changes as a function of ageing. Their study revealed that older participants showed decreased responses to music expressing negative emotions, while their perception of happy emotions remained stable.

Emotion plays an important role in music. Even infants have been found to be capable of identifying emotions in musical excerpts (Nawrot, 2003). However, recognition of emotion in music has received little attention so far. A new study by Lima and Castro published in Cognition and Emotion examined the effects of ageing on the recognition of emotions in music. Previous studies looking at emotion recognition in other modalities have revealed that increasing age is associated with a decline in the recognition of some emotions but not others (for more information see meta-analysis by Ruffman et al. (2008)). Laukka and Juslin (2007) examined the effects of ageing on emotion recognition in music comparing young adults (around 24) and older adults (older than 65). Their results identified that older adults had more difficulty recognizing fear and sadness in both music and speech prosody, whereas no differences were observed for anger, happiness and neutrality.

The sample used by Lima et al. was of 114 healthy adults (67 female). They were aged between 17 and 84 years, and were divided into three groups with 38 participants each: younger(mean age=21.8 years), middle-aged (mean age=44.5 years) and older adults (mean age=67.2 years). Each group listened to 56 short musical excerpts that expressed happiness, sadness, fear/threat and peacefulness. Each category was consisted of 14 stimuli.

The results revealed significant age-related changes associated with specific emotions. More specifically, the authors identified a progressive decline in responsiveness to sad and scary music. No difference was found in happy music. Differences between age groups were also observed in the pattern of misclassifications for sad and peaceful music. Younger participants perceived more sadness in peaceful music, older participants perceived more peacefulness. This could be due to the structural features of peaceful and sad songs, which are both characterised by slow tempo. Future studies could further investigate this. In addition to that, Lima et al. took into account the years of musical training that the participants had. This analysis revealed a positive association between music training and the categorisation of musical emotions.

One possible explanation for the main findings of this study suggests that the decline in the recognition of particular emotions might reflect the age-related neuropsychological decline in brain regions (such as the amygdala) involved in emotion processing. Previous studies have showed that distinct brain regions are involved in the perception of different emotions (Mitterschiffthaler et al., 2007). Another possible explanation is the age-related positivity bias (Mather & Carstensen, 2005; Carstensen & Mikels, 2005). Age-related positivity bias suggests that people get older, they experience fewer negative emotions.

Future studies could attempt to identify particular brain regions involved in emotion recognition at different ages. Furthermore, since the age-related positivity bias might not be universal (older Chinese participants looked away from happy facial expressions and not from negative ones, see Fung et al., 2008), it’d be very interesting to investigate the effects of ageing on emotion recognition in music in participants from different cultures.

The “Singing” Mouse?

22/12/2010 1 comment

A tweeting mouse?

A Japanese group led by Arikuni Uchimura managed to create a genetically-engineered mouse that tweets like a bird! The “singing” mouse is part of the team’s “Evolved Mouse Project”, in which they use genetically modified mice that are prone to mutations.

The “singing” mouse was born by chance but this particular trait will be passed on to future generations. Uchimura who dreams of creating a real life version of Mickey Mouse (!) hopes that this creation could provide clues on how human language evolved…

You can hear the talented animal here. Sounds a bit like squeaking to be honest…

Moreover, a case of a “singing” mouse was reported much earlier – in 1936. You can read the Times article here. More recently, another group had identified patterns of singing in male mice. You can read the article here.

Walking With Music: Useful Tool for Gait Training in Parkinson’s Disease

20/11/2010 9 comments

Scientists from Canada showed that listening to music during gait training could help patients with Parkinson’s Disease.

Gait disturbances is one of the main characteristics of Parkinson’s Disease (PD). It has been associated with increased risk of falling, diminished mobility, and reduced quality of life. In addition to that, patients with PD have difficulties when it comes to dual tasking; walking and performing a secondary task like talking. This is known as dual task interference and is thought to be associated with the incidents of falling amongst people with PD.

One rehabilitation strategy of PD that seems to be effective includes the use of rhythmic auditory during gait training sessions. de Bruin and colleagues attempted to investigate whether a similar effect would be observed if the cue was a musical piece or “walking song”. They did this by implementing a 13-week home based music and walking program on 11 volunteers with PD. The music used were commercially available songs, unaltered, familiar and enjoyable to individual patients. The tempo of the selected song was matched to each patient’s walking cadence. The control group attended a gait training programme that wasn’t acco

The group of PD patients that underwent a 13 week music programme showed improved gait performance compared to the control group. In particular, marginal improvements were reported in gait velocity, cadence, and stride time. The same patterns of improvements were observed in the dual task condition. Moreover, listening to music during training did not lead to increased falls. This suggests that this practice is safe.

The mechanism that led to these improvements is not fully understood. One possible explanation proposed that music may have enhanced gait performance through increasing the patients’ affective arousal. This is possible as the arousal potential of the music was intentionally high in this study; the pieces were selected based on familiarity and enjoyment. Another explanation suggests that training and listening to music could be seen as a dual tasking condition. Listening to music can be seen as a cognitive demanding task and practising two tasks at the same time (walking and listening to music) allows the improvement of task-coordination skills.

The results of this study indicate that the use of cadence-matched, salient music to accompany walking is a feasible and enjoyable intervention for use amongst patients with mild to moderate PD.

Major depression associated with impaired processing of emotion in music?

24/07/2010 4 comments

Previous studies have found that the processing of faces and voices is negatively biased in major depression. Naranjo and colleagues were the first to investigate possible effects of major depression on the recognition of emotion in music. According to the authors:

as music is not directly linked to interpersonal communication, comparing a musical task with a facial and a vocal one will allow us to determine whether the impaired processing of emotional stimuli in depression is limited to interpersonal contexts

23 depressed patients and 23 matched healthy controls participated in this study. Their affective information processing was assessed through musical, vocal and facial emotion recognition tasks. Depressed participants were found to be impaired in all tasks. More specifically:

Depressed participants were less accurate in their recognition of peaceful and happy musical excerpts, for neutral and surprised voices and fearful, neutral and angry faces (whether displayed briefly or for a longer period). The depressed participants rated the intensity of the emotion higher than the control group for sad and frightening musical excerpts, and for the negative emotions of sadness, anger and fear in vocal and facial stimuli. However the depressed participants rated the peaceful musical excerpts less intense than the control group. Neutral voices and faces were frequently interpreted by depressed participants as expressing a negative emotion

These results show that there is a general emotional processing impairment in depressed participants. However, it’s hard to say that this impairment is due to the disorder itself. It could possibly be attributed to the anti-depressant medication all the participants were taking – previous research on this topic suggests that blunting of emotion is one of the effects of medication in healthy participants (Fu et al., 2004).
