Newborns discriminate utterance-level prosodic contours

Prosody is the fundamental organizing principle of spoken language, carrying lexical, morphosyntactic, and pragmatic information. It, therefore, provides highly relevant input for language development. Are infants sensitive to this important aspect of spoken language early on? In this study, we asked whether infants are able to discriminate well-formed utterance-level prosodic contours from ill-formed, backward prosodic contours at birth. This deviant prosodic contour was obtained by time-reversing the original one, and super-imposing it on the otherwise intact segmental information. The resulting backward prosodic contour was thus unfamiliar to the infants and ill-formed in French. We used near-infrared spectroscopy (NIRS) in 1-3-day-old French newborns (n = 25) to measure their brain responses to well-formed contours as standards and their backward prosody counterparts as deviants in the frontal, temporal, and parietal areas bilaterally. A cluster-based permutation test revealed greater responses to the Deviant than to the Standard condition in right temporal areas. These results suggest that newborns are already capable of detecting utterance-level prosodic violations at birth, a key ability for breaking into the native language, and that this ability is supported by brain areas similar to those in adults.

Research Highlights

• At birth, infants have sophisticated speech perception abilities.
• Prosody may be particularly important for early language development.
• We show that newborns are already capable of discriminating utterance-level prosodic contours.
• This discrimination can be localized to the right hemisphere of the neonate brain.

     

Self-awareness and emotional intensity

Abstract

Influences of mood on qualitative aspects of cognitive processing are examined within a semantic priming paradigm. The priming effect reflects the reduction of latency for a lexical decision task when a target word is presented in combination with an associatively related prime word. The effect was higher for subjects in whom positive affect had been induced than for a control group, if prime and target were high-associatively related. There was no effect of mood on priming for low-associatively related prime-target pairs. The results are interpreted in terms of a general facilitating influence of mood on spreading activation independent of the affective quality of the processed material.     

Trajectories of perceived superiority across the transition to marriage

ABSTRACT

Perceived superiority, the tendency to regard one’s own relationship as better than other people’s relationships, is a key relationship maintenance mechanism. Little is known about whether and how it changes during the transition to marriage, a pivotal moment in most couples’ life cycle. In a longitudinal study following 97 couples for three waves across the transition, men presented stable perceived superiority, whereas women presented a curvilinear change in superiority perceptions, with a substantial increase in perceived superiority between T1 and T2 and a significantly reduced change between T2 and T3. In addition, trajectories differed according to partners’ commitment level. More committed and less committed partners both showed a curvilinear change in perceived superiority, though following different patterns. Results point to the functional value of perceived superiority, which emerges as a strategy aimed at sustaining partners through the challenges deriving from the transition to marriage.     

Exploring the Role of Sport Sense of Community in Perceived Athlete Burnout,Sport Motivation,and Engagement

The main purpose of this work was to examine the relationships between the sport sense of community, athlete burnout, engagement, and motivation in adolescent athletes, adopting a longitudinal perspective, and using both person- and variable-centred approaches. A total of 250 adolescent athletes were involved in the study. Athletes' perceptions of burnout, engagement and motivation significantly differed across two different clusters: high and low sport sense of community profiles. Consistent with our hypothesis, sport sense of community dimensions (i.e., satisfaction of needs and influence) negatively predicted athlete burnout and controlled motivation, and positively predicted engagement and autonomous motivation six months later.

Lay Summary: Athlete burnout is associated with negative consequences for athletes’ well-being, whereas engagement reflects a positive state. The sport sense of community refers to the athletes’ relationship with their sport environment. In this study, we provided preliminary evidence of the protective role of the sport sense of community on athlete burnout.
