The acquisition of emotion-laden words from childhood to adolescence

Studies investigating how children acquire emotional vocabularies have mainly focused on words that describe feelings or affective states (emotion-label words, e.g., joy) trough subjective assessments of the children’s lexicon reported by their parents or teachers. In the current cross-sectional study, we objectively examined the age of acquisition of words that relate to emotions without explicitly referring to affective states (emotion-laden words, e.g., cake, tomb, rainbow) using a picture naming task. Three hundred and sixty participants belonging to 18 age groups from preschool to adolescence overtly named line drawings corresponding to positive, negative, and neutral concrete nouns. The results of regression and mixed model analyses indicated that positive emotion-laden words are learnt earlier in life. This effect was independent of the contribution of other lexical and semantic factors (familiarity, word frequency, concreteness, word length). It is proposed that the prioritized acquisition of positive emotion-laden words might be the consequence of the communicative style and contextual factors associated with the interaction between children and caregivers. We also discuss the implications of our findings for proposals that highlight the role of language in emotion perception and understanding

“Avoiding or approaching eyes”? Introversion/extraversion affects the gaze-cueing effect

We investigated whether the extra-/introversion personality dimension can influence processing of others’ eye gaze direction and emotional facial expression during a target detection task. On the basis of previous evidence showing that self-reported trait anxiety can affect gaze-cueing with emotional faces, we also verified whether trait anxiety can modulate the influence of intro-/extraversion on behavioral performance. Fearful, happy, angry or neutral faces, with either direct or averted gaze, were presented before the target appeared in spatial locations congruent or incongruent with stimuli’s eye gaze direction. Results showed a significant influence of intra-/extraversion dimension on gaze-cueing effect for angry, happy, and neutral faces with averted gaze. Introverts did not show the gaze congruency effect when viewing angry expressions, but did so with happy and neutral faces; extraverts showed the opposite pattern. Importantly, the influence of intro-/extraversion on gaze-cueing was not mediated by trait anxiety. These findings demonstrated that personality differences can shape processing of interactions between relevant social signals

Learning Abstract Words and Concepts: Insights from Developmental Language Disorder

Some explanations of abstract word learning suggest that these words are learnt primarily from linguistic input, using statistical co-occurrences of words in language whereas concrete words can also rely on non-linguistic, experiential information. According to this hypothesis, we expect that, if the learner is not able to fully exploit the information in the linguistic input, abstract words should be affected more than concrete ones. Embodied approaches, instead, argue that both abstract and concrete words can rely on experiential information and, therefore, there might not be any linguistic primacy. Here, we test the role of linguistic input in the development of abstract knowledge with children with Developmental Language Disorder (DLD) and Typically Developing (TD) children aged 8-13. We show that DLD children, who by definition have impoverished language, do not show a disproportionate impairment for abstract words in lexical decision and definition tasks. These results indicate that linguistic information does not have a primary role in the learning of abstract concepts and words, rather, it would play a significant role in semantic development across all domains of knowledge

Incidental retrieval of prior emotion mimicry.

When observing emotional expressions, similar sensorimotor states are activated in the observer, often resulting in physical mimicry. For example, when observing a smile, the zygomaticus muscles associated with smiling are activated in the observer, and when observing a frown, the corrugator brow muscles. We show that the consistency of an individual's facial emotion, whether they always frown or smile, can be encoded into memory. When the individuals are viewed at a later time expressing no emotion, muscle mimicry of the prior state can be detected, even when the emotion itself is task irrelevant. The results support simulation accounts of memory, where prior embodiments of other's states during encoding are reactivated when re-encountering a person

Multicenter evaluation of a new chromogenic factor X assay in plasma of patients on oral anticoagulants

A new factor X (FX) assay based on the chromogenic substrate S-2337 was compared with the coagulation screening method Thrombotest (TT) in 1431 plasma samples from 188 patients followed up for 6-8 months on long-term oral anticoagulants. In all the participating laboratories, the results of the methods were highly correlated (P < 0. 001). The FX values corresponding on the regression line to a TT therapeutic interval of 5-15 per cent ranged from 8 to 36 per cent in different laboratories. The results of the two methods were highly concordant in classifying the patients within or outside the therapeutic interval. The precision of the FX method was no better than that of TT both in normal and pathological samples. On the basis of these findings, the FX chromogenic method appears to be a potentially promising new approach to the problem of anticoagulant therapy control, providing that a longitudinal study confirm its clinical suitability
