Very shy children may process some facial expressions differently

03.01.2005


Children who appear to have higher levels of shyness, or a particular gene, appear to have a different pattern of processing the signals of interpersonal hostility, according to a study in the January issue of The Archives of General Psychiatry, one of the JAMA/Archives journals.



According to background information in the article, "Neuroimaging studies are beginning to clarify the relationship between the brain’s cortical and subcortical activity in regulating the emotional and cognitive functions of behavior." … "A temperamental disposition toward the avoidance of novel and uncertain situations together with a set of behaviors that indicate shyness and discomfort in social interactions are comprehensively named childhood shyness, or behavioral inhibition (BI). Children with high indexes of shyness-BI are at a heightened risk of developing anxiety disorders, in particular social phobia."

Marco Battaglia, M.D., from the Istituto Scientifico San Raffaele, Milan, Italy, and colleagues analyzed the responses of 49 third- and fourth-grade schoolchildren (characterized as shy) to different emotional facial expressions. The researchers showed the study participants pictures of boys and girls with facial expressions that depicted joy, neutrality, and anger. The study participants were assessed through questionnaires and responses were also recorded with electrodes measuring brain wave activity.


The researchers found that the shyness-BI index and the presence of particular forms of the serotonin transporter promoter gene predicted smaller responses to overtly hostile and neutral facial expressions in certain regions of the brain. The researchers suggest that their findings indicate diminished brain involvement and partially impaired reading in response to some facial expressions. "Shy children have been shown to provide relatively distinct physiologic responses in a variety of contexts," the researchers write. "These data suggest that a biased pattern of processing emotional information of social relevance can be recognized and characterized…early in life."

Im Focus: Superconducting vortices quantize ordinary metal

Russian researchers together with their French colleagues discovered that a genuine feature of superconductors -- quantum Abrikosov vortices of supercurrent -- can also exist in an ordinary nonsuperconducting metal put into contact with a superconductor. The observation of these vortices provides direct evidence of induced quantum coherence. The pioneering experimental observation was supported by a first-ever numerical model that describes the induced vortices in finer detail.

These fundamental results, published in the journal Nature Communications, enable a better understanding and description of the processes occurring at the...

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
