Facial expressions and speech acts: experimental evidences on the role of the upper face as an illocutionary force indicating device in language comprehension

Language scientists have broadly addressed the problem of explaining how language users recognize the kind of speech act performed by a speaker uttering a sentence in a particular context. They have done so by investigating the role played by the illocutionary force indicating devices (IFIDs), i.e., all linguistic elements that indicate the illocutionary force of an utterance. The present work takes a first step in the direction of an experimental investigation of non-verbal IFIDs because it investigates the role played by facial expressions and, in particular, of upper-face action units (AUs) in the comprehension of three basic types of illocutionary force: assertions, questions, and orders. The results from a pilot experiment on production and two comprehension experiments showed that (1) certain upper-face AUs seem to constitute non-verbal signals that contribute to the understanding of the illocutionary force of questions and orders; (2) assertions are not expected to be marked by any upper-face AU; (3) some upper-face AUs can be associated, with different degrees of compatibility, with both questions and orders.     

Neural substrates of the ‘low‐level’ system for speech articulation: Evidence from primary opercular syndrome

We describe a patient with progressive disorder of speech, without language impairment (opercular syndrome). Morphometric analysis confirmed asymmetric volume reduction of the precentral areas (>left). Diffusion imaging showed significant white matter changes in the left frontal lobe, with specific involvement of the left corticobulbar tract and connections between supplementary/pre‐supplementary motor areas and the frontal operculum (frontal aslant tract). We suggest that the organization of expressive language includes a ‘low level’ motor system principally distributed in the left hemisphere that shows specific susceptibility to neurodegeneration, distinct from neural systems subtending praxic, and cognitive aspects of language.     

Bidirectional relations between different forms of prosocial behaviors and substance use among female college student athletes

Bidirectional, longitudinal relations between alcohol and marijuana use and prosocial behaviors in women college student athletes were examined. Participants were 187 female college students (M_age = 19.87 years; 91% White) who completed questionnaires on their use of marijuana and alcohol, and six forms of prosocial behaviors across 6 years (2004–2010). The findings yield overall evidence that earlier marijuana use predicted lower levels of most specific forms of prosocial behaviors for women athletes in later young adulthood. Early expressions of altruistic behaviors predicted less marijuana use in later young adulthood. Expression of public prosocial behaviors early in young adulthood predicted higher levels of hazardous drinking in late young adulthood. These novel findings have important implications for links between prosocial development and substance use in women college athletes.     

Analysis of the factor structure of the Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ-3) in Spanish secondary-school students through exploratory structural equation modeling

The aims of the present study were: (1) to assess the factor structure of the SATAQ-3 in Spanish secondary-school students by means of exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) models; and (2) to study its invariance by sex and school grade. ESEM is a technique that has been proposed for the analysis of internal structure that overcomes some of the limitations of EFA and CFA. Participants were 1559 boys and girls in grades seventh to tenth. The results support the four-factor solution of the original version, and reveal that the best fit was obtained with ESEM, excluding Item 20 and with correlated uniqueness between reverse-keyed items. Our version shows invariance by sex and grade. The differences between scores of different groups are in the expected direction, and support the validity of the questionnaire. We recommend a version excluding Item 20 and without reverse-keyed items.     

The willingness of medical students to use Facebook as a training channel for professional habits: the case of influenza vaccination

The low acceptance of influenza vaccination by both medical students and healthcare workers (HCWs) signals the need for innovative strategies. We administered an anonymous questionnaire to 410 University of Barcelona medical students who were asked about using the Internet to find information on influenza vaccination of HCWs and about their willingness to use technical and informal Facebook pages as an information channel on this topic. Of the 410 participants, 74.1 percent were female and 58.3 percent were in the first preclinical 3-year university cycle. A total of 7.6 percent participants reported using the Internet for queries on influenza vaccination, 89.8 percent reported that they were Facebook users, and 275 (67.1 percent) would accept an invitation from the technical or informal Facebook pages. The technical Web site would be actively followed by 77, or by 30.0 percent of those who would accept the invitation and the informal site by 116 (43.6 percent of those who would accept). The marked willingness to use Facebook to obtain information on the influenza vaccination of HCWs potentially opens a new window in health education: social networks could be used to help create professional habits. Students would be more likely to engage with this type of Facebook page if the contents were informal rather than highly technical.     

The neuropsychological correlates of cognitive insight in healthy participants

Cognitive insight is the ability to monitor and correct one's own erroneous convictions. The Beck Cognitive Insight Scale (BCIS) assesses two sub‐dimensions of cognitive insight: self‐reflectiveness (SR), which is the attitude of questioning one's own judgments; and self‐certainty (SC), which is the unwillingness to modify and correct one's own convictions. There is little information about cognitive insight in healthy participants (HP). Here we investigated the socio‐demographic and neuropsychological correlates of cognitive insight in 50 HP who were administered the BCIS and a comprehensive neuropsychological battery. The global BCIS R‐C index correlated positively with age and WCST perseverative errors. SR correlated positively with age. These data support the hypothesis that a less self‐reflective and more self‐confident style is cognitively functional in HP. Thus, what has been found malfunctioning in mental illnesses is adaptive in HP. Future studies should consider a wider range of factors that might affect this complex construct.

Naming with proper names: the left temporal pole theory

Existing empirical data on proper names processing are critically reviewed in trying to understand which tasks may involve the left temporal pole, which proper name related functions are supported by this structure and eventually offer some speculations about why these functions might have developed in this location in the course of human evolution. While clinical group studies support the idea that proper name processing takes place in the left temporal pole, single case studies of selective proper name anomia or sparing, as well as neuroimaging studies, suggest the involvement of a larger neural network. Within this network, an important role may be played by the ventro-medial prefrontal cortex, including areas critical in social interaction. The differentiation in the brain of proper name processing from common names processing could in part be due to social pressure, favouring a neural system able to more efficiently and unambiguously sustain designating categories or designating individual entities. The activation of the left temporal pole in proper name processing is shown to increase with age. Longer social interaction may thus contribute to convey proper names processing toward areas closer to those supporting social cognition.     

Newborns' preference for goal-directed actions

The central role of sensory-motor representations in cognitive functions is almost universally accepted. However, determining the link between motor execution and its sensory counterpart and when, during ontogenesis, this link originates are still under investigation. The aim of the present study is to investigate whether at birth this link is already present and 2-day-old newborns are able to discriminate between visual cues indicating goal-directed or non-goal-directed actions. Here, with a preferential looking technique, a hand grasping a ball was the observed movement and we orthogonally manipulated the three factors necessary to successfully reach the goal: (a) presence of the ball, (b) direction of the arm movement, and (c) hand shaping. Results indicated that newborns orient more frequently and look longer at a hand shape for whole hand prehension but only when the movement is directed away from the body and toward the external world. In addition, newborns prefer the away from the body movement only when the object is present. We argue that newborns prefer a movement directed toward the external world only when it may develop into a purposeful movement because of the presence of the to-be-grasped object. Overall, our results support the existence of primitive sensory-motor associations since the first days after birth.     

Dynamic time warping: a new method in the study of poor handwriting

Poor handwriting is a diagnostic criterion for developmental coordination disorder. Typical of poor handwriting is its low overall quality and the high variability of the spatial characteristics of the letters, usually assessed with a subjective handwriting scale. Recently, Dynamic Time Warping (DTW), a technique originally developed for speech recognition, was introduced for pattern recognition in handwriting. The present study evaluates its application to analyze poor handwriting. Forty children attending Dutch mainstream primary schools were recruited and based on their scores on the Concise Evaluation Scale for Children's Handwriting (Dutch abbreviation: BHK), 20 good and 20 poor writers (of whom 13 were scheduled for handwriting intervention) were identified. The groups were matched for age (7-9 years), school grade (grades 2 and 3) and handedness. The children subsequently wrote sequences of the letter "a" on a graphics tablet in three conditions (normal, fast, and accurate). Classical kinematics were obtained and for each individual letter DTW was used to calculate the distance from the mean shape. The DTW data revealed much higher variability in the letter forms of the poor writers that was independent of the kinematic results of larger trajectories, faster movements, and higher pen pressure. The current results suggest that DTW is a valid and objective technique for letter-form analysis in handwriting and may hence be useful to evaluate the rehabilitation treatments of children suffering from poor handwriting. In education research it may be exploited to explore how children (should) learn to write.
