Abstract

Here we study polysemy as a potential learning bias in vocabulary learning in children. Words of low polysemy could be preferred as they reduce the disambiguation effort for the listener. However, such preference could be a side-effect of another bias: the preference of children for nouns in combination with the lower polysemy of nouns with respect to other part-of-speech categories.

Our results show that mean polysemy in children increases over time in two phases, i.e. a fast growth till the 31st month followed by a slower tendency towards adult speech. In contrast, this evolution is not found in adults interacting with children. This suggests that children have a preference for non-polysemous words in their early stages of vocabulary acquisition. Interestingly, the evolutionary pattern described above weakens when controlling for syntactic category (noun, verb, adjective or adverb) but it does not disappear completely, suggesting that it could result from a combination of a standalone bias for low polysemy and a preference for nouns.

Abstract

In their first weeks of life preterm infants are deprived of developmentally appropriate stimuli, including their mother’s voice. The current study explores the immediate association of two preterm infant behaviours (open eyes or smiling) with the quality of a mother’s infant-directed speech and singing. Participants are 20 mothers who are asked to speak and sing to their medically stable infants placed in incubators. Eighty-four vocal samples are extracted when they occur in the presence of an infant’s behavioural display and compared with random selections during periods of absence of target behavioural display. The results show that infant-directed maternal voice presents more marked emotional qualities when infants display a behavioural change than when infants are passive and expressionless. Specifically, higher values of mean pitch and maximum sound pressure level, as well as greater variability of these parameters are associated with a behavioural display.

Abstract

Selective mutism (SM) is a developmental disorder characterized by a child’s inability to speak in certain contexts and/or in the presence of unfamiliar interlocutors. This work proposes a critical discussion of the most recent studies on SM, with respect to clinical and diagnostic features, as well as the etiology and treatment of this disorder. At present, all research work supports the hypothesis that SM is a complex anxiety disorder with multifactorial etiology (interaction among biological and environmental causes). The latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013) places SM mutism among “Anxiety Disorders”, and no longer among “Other Childhood, Infant and Adolescent Disorders” (as in DSM-IV). Other important aspects relate to cognitive biases and emotional states at the base of SM, which partly explain the disorder’s persistence and represent an important objective of intervention work. No data in the literature point to a total remission of SM, but good results are achieved with cognitive behavior intervention and multimodal therapy (MMT) involving a variety of child interaction contexts.

Abstract

Collaborative remembering is essential to enabling teams to build shared understanding of projects and their progress. This article presents an analysis of collaborative remembering sequences in a corpus of interactions collected in a workplace where a team of designers developed a video television commercial. On the basis of coding and analysing linguistic and bodily behaviors in 158 such sequences, extracted from over 45 hours of video recordings, recurrent patterns of collaborative remembering processes were identified, relating to the interplay of work roles. This article shows that collaborative remembering in the design studio is structured by behavioural, interactive and social factors.

Abstract

Frustration in traffic is one of the causes of aggressive driving. Knowledge whether a driver is frustrated may be utilized by future advanced driver assistance systems to counteract this source of crashes. One possibility to achieve this is to automatically recognize facial expressions of drivers. However, only little is known about the facial expressions of frustrated drivers. Here, we report the results of a driving simulator study investigating the facial muscle activity that comes along with frustration. Twenty-eight participants were video-taped during frustrated and non-frustrated driving situations. Their facial muscle activity was manually coded according to the Facial Action Coding System. Participants showed significantly more facial muscle activity in the mouth region. Thus, recording facial muscle behavior potentially provides traffic researchers and assistance system developers with the possibility to recognize frustration while driving.

Abstract

To advance understanding of the mechanisms allowing for team coordination (TC) in complex motor actions, we conducted a qualitative study with eight elite hand-to-hand circus acrobats. Data collection consisted of field observations, an open-ended interview with the participants’ head coach, and focus group interviews with all acrobats. Data analysis yielded three higher order themes: TC, collective efficacy (CE), and TC-CE linkage. Teammates’ shared and complementary mental models, as well as implicit and explicit communication dynamics, emerged as formative sub-themes of TC; self-efficacy and other’s-efficacy emerged as reflective sub-themes of CE. Our findings also suggest that TC is likely inter-related to CE in a systemic fashion. Practitioners should encourage the development of both shared and complementary models of thinking, while promoting verbal and non-verbal communication skills. Finally, increasing teammates’ confidence in themselves and in their teammates can help in the development of CE as well as the enhancement of TC.
