- When words matter: a cross-cultural perspective on lyrics and their relationship to musical emotionsPublication . Barradas, Gonçalo T.; Sakka, Laura S.Several studies have investigated emotional reactions to instrumental music. However, studies on the effect of lyrics on emotions are limited. Previous studies suggest that the importance of lyrics may vary cross-culturally. The aim of this study was twofold: to investigate the effects of lyrics on aroused emotions and psychological mechanisms with music and to explore whether these differ cross-culturally. Fifty participants from Portugal and Sweden listened to six musical stimuli based on two songs, one representing each culture. These were presented in three versions each: the original, an instrumental, and the instrumental version with lyrics on the screen. The Portuguese and Swedish participants differed notably: the presence of lyrics did not affect listeners’ happiness in neither group as predicted, but did increase sadness, albeit only in the Portuguese group. Lyrics also increased nostalgia for the Portuguese listeners as predicted and surprise-astonishment for the Swedish listeners. Regarding the mechanisms, lyrics increased the activation of episodic memory in both groups, and the activation of evaluative conditioning, contagion, and visual imagery in the Portuguese group. The present study indicates that lyrics have an effect on musical emotions and mechanisms which vary between groups of different cultural backgrounds.
- Emotional reactions to music in dementia patients and healthy controls: differential responding depends on the mechanismPublication . Barradas, Gonçalo T.; Juslin, Patrik N.; Bermúdez i Badia, SergiMusic is frequently regarded as a unique way to connect with dementia patients. Yet little is known about how persons with dementia respond emotionally to music. Are their responses different from those of healthy listeners? If so, why? The present study makes a first attempt to tackle these issues in a Portuguese context, with a focus on psychological mechanisms. In Experiment 1, featuring 20 young and healthy adults, we found that musical excerpts which have previously been shown to activate specific emotion induction mechanisms (brain stem reflex, contagion, episodic memory, musical expectancy) in Sweden were valid and yielded predicted emotions also in Portugal, as indexed by self reported feelings, psychophysiology, and post hoc mechanism indices. In Experiment 2, we used the same stimuli to compare the responses of 20 elderly listeners diagnosed with Alzheimer’s disease (AD) with those of 20 healthy lis teners. We controlled for cognitive functioning (Mini-Mental State Examination) and depression (Geriatric Depression Scale). Our predictions about how mechanisms would be differentially affected by decline in brain regions associated with AD received support in that AD patients reported significantly lower levels of (a) sadness in the contagion condition, (b) happiness and nostalgia in the episodic memory condition, and (c) anxiety in the musical expectancy condition. By contrast, no significant difference in reported surprise was found in the brain stem reflex condition. Implications for musical interventions aimed at dementia are discussed, highlighting the key role that basic research may play in developing applications.
