From melody to lexical tone: Musical ability enhances specific aspects of foreign language perception

Previous research shows that music ability provides positive effects on language processing. This study aims at better clarifying the involvement of different linguistic subdomains in this cross-domain link, assessing whether or not musicality and music expertise enhance phonological and lexical tone processing of Mandarin Chinese. In two experiments different groups of adults and children with no previous experience in tonal languages, were invited to perform a same–different task trying to detect phonological and tonal variations in pairs of sequences of monosyllabic Mandarin Chinese words. Main results show that all subjects perform significantly better in detecting phonological variations rather than tonal ones. They also show that both melodic proficiency and music expertise are good predictors for a better tonal, but not phonological identification. Data lead to a model of music-to-language transfer effect in which musicality selectively affects linguistic intonation while leaving phonological processing substantially unaffected.     

Musical training generalises across modalities and reveals efficient and adaptive mechanisms for reproducing temporal intervals

Expert musicians are able to time their actions accurately and consistently during a musical performance. We investigated how musical expertise influences the ability to reproduce auditory intervals and how this generalises across different techniques and sensory modalities. We first compared various reproduction strategies and interval length, to examine the effects in general and to optimise experimental conditions for testing the effect of music, and found that the effects were robust and consistent across different paradigms. Focussing on a ‘ready-set-go’ paradigm subjects reproduced time intervals drawn from distributions varying in total length (176, 352 or 704 ms) or in the number of discrete intervals within the total length (3, 5, 11 or 21 discrete intervals). Overall, Musicians performed more veridical than Non-Musicians, and all subjects reproduced auditory-defined intervals more accurately than visually-defined intervals. However, Non-Musicians, particularly with visual stimuli, consistently exhibited a substantial and systematic regression towards the mean interval. When subjects judged intervals from distributions of longer total length they tended to regress more towards the mean, while the ability to discriminate between discrete intervals within the distribution had little influence on subject error. These results are consistent with a Bayesian model that minimizes reproduction errors by incorporating a central tendency prior weighted by the subject's own temporal precision relative to the current distribution of intervals. Finally a strong correlation was observed between all durations of formal musical training and total reproduction errors in both modalities (accounting for 30% of the variance). Taken together these results demonstrate that formal musical training improves temporal reproduction, and that this improvement transfers from audition to vision. They further demonstrate the flexibility of sensorimotor mechanisms in adapting to different task conditions to minimise temporal estimation errors.     

A convention or (tacit) agreement betwixt us: on reliance and its normative consequences

The aim of this paper is to clarify what kind of normativity characterizes a convention. First, we argue that conventions have normative consequences because they always involve a form of trust and reliance. We contend that it is by reference to a moral principle impinging on these aspects (i.e. the principle of Reliability) that interpersonal obligations and rights originate from conventional regularities. Second, we argue that the system of mutual expectations presupposed by conventions is a source of agreements. Agreements stemming from conventions are “tacit” in the sense that they are implicated by what agents do (or forbear from doing) and without that any communication between them is necessary. To justify this conclusion, we assume that: (1) there is a salient interpretation, in some contexts, of everyone’s silence as confirmatory of the others’ expectations (an epistemic assumption), and (2) the participating agents share a value of not being motivated by hostile attitudes (a motivational assumption). By clarifying the relation between conventions and agreements, the peculiar normativity of conventions is analyzed.     

Mirror symmetry opposes splitting of chromatically homogeneous surfaces

Chromatically homogeneous surfaces can be seen as single figures but also as two or more overlapping figures. Local factors such as relatability have been proposed in order to explain perception of two or more figures (Kellman and Shipley, 1991 Cognitive Psychology 23 141-221). However, even when these factors are at work, there are conditions favouring the perception of a single figure, which have not been explored so far. Here we propose that one such factor is the mirror symmetry of the surface. Three experiments were designed to test: (a) the main hypothesis, that mirror symmetry enhances perception of a single figure; (b) the role of orientation; (c) the effect of the number of axes of symmetry. The results show that (i) there is a good general correlation between mirror symmetry and perception of a single figure; (ii) vertical and horizontal axes of symmetry are the most effective; and (iii) the more axes of symmetry a surface has, the more likely is the perception of a single figure. These results suggest that mirror symmetry is an important factor in the perception of chromatically homogeneous displays. Some explanations are discussed, particularly one based on the rejection-of-coincidence principle [Rock, 1983 The Logic of Perception (Cambridge, MA: MIT Press)], and a version of the minimum principle in which the strength of the global solution depends on symmetry, whereas the strength of the splitting solution depends on the strength of local factors. In brief, global and local factors compete in determining the perceptual outcome in chromatically homogeneous surfaces.

Children's Moral Emotion Attribution in the Happy Victimizer Task: The Role of Response Format

Previous research in the happy victimizer tradition indicated that preschool and early elementary school children attribute positive emotions to the violator of a moral norm, whereas older children attribute negative (moral) emotions. Cognitive and motivational processes have been suggested to underlie this developmental shift. The current research investigated whether making the happy victimizer task less cognitively demanding by providing children with alternative response formats would increase their attribution of moral emotions and moral motivation. In Study 1, 93 British children aged 4–7 years old responded to the happy victimizer questions either in a normal condition (where they spontaneously pointed with a finger), a wait condition (where they had to wait before giving their answers), or an arrow condition (where they had to point with a paper arrow). In Study 2, 40 Spanish children aged 4 years old responded to the happy victimizer task either in a normal or a wait condition. In both studies, participants' attribution of moral emotions and moral motivation was significantly higher in the conditions with alternative response formats (wait, arrow) than in the normal condition. The role of cognitive abilities for emotion attribution in the happy victimizer task is discussed.     

The moderating role of internalising negative emotionality in the relation of self-regulation to social adjustment in Italian preschool-aged children

The purpose of this study was to examine the moderating role of internalising negative emotionality (i.e., anxious, concerned, and embarrassed displays) in the association between children's self-regulation and social adjustment. Seventy-four Italian children (44 girls, 30 boys; M age?=?35.05 months, SD?=?3.57) were assessed using two self-regulation tasks. Internalising negative emotionality was assessed through observations of children's emotion expressions during the tasks. Teachers evaluated children's social competence and internalising and externalising problems. Results demonstrated that among children who exhibited internalising negative emotionality, self-regulation was positively associated with social competence and negatively related to externalising problems. Our results suggest that self-regulation may play a crucial role for social adjustment when children show emotions such as anxiety and embarrassment during challenging situations.     

Daydreaming to navigate the social world: What we know,what we don't know,and why it matters

A substantial portion of daily life is spent daydreaming—that is, engaged in thought independent of, and unrelated to, goals in the external environment. We argue that this naturally occurring, unconstrained cognition is a vital, but currently underappreciated, form of social cognition that enables navigation of the social world. First, we present the results of a meta‐analysis of neuroimaging studies which illustrate the shared neural basis of daydreaming and social cognition (including regions of the anterior temporal lobes and the posterior cingulate cortex). Second, we review evidence regarding the frequency, correlates, and adaptive outcomes of social daydreaming, cumulative findings that point to the adaptive value of imaging others during this offline state. We end by encouraging cross‐fertilization between daydreaming research and domains of social psychology (goal pursuit, social interactions, and close relationships), which we hope will foster mutually beneficial directions for understanding the role that unconstrained thinking plays in social life.
