Infant sensitivity to negative emotional expressions develops at around six months

14.08.2008
Scientists working in the Academy-funded Research Programme on Neuroscience (NEURO) have discovered important changes in the way that infants react to another person’s face at age 5–7 months.

Infants aged 5 months react very differently to a fearful face than those aged 7 months. “At the age of 7 months babies will watch a fearful face for longer than a happy face, and their attentiveness level as measured by EEG is higher after seeing a fearful than a happy face.

By contrast, infants aged 5 months watch both faces, when they are shown side by side, for just as long, and there is no difference in the intensity of attention in favour of the fearful face,” said Mikko Peltola, researcher at the University of Tampere, at the Academy’s Science Breakfast this week.

It seems that at age 6 months, important developmental changes take place in the way that infants process significant emotional expressions. A fearful face attracts intense attention by the age of 7 months. In addition, it takes longer for infants to shift their attention away from fearful than from happy and neutral faces.

“Our interpretation of this is to suggest that the brain mechanisms that specialise in emotional response and especially in processing threatening stimuli regulate and intensify the processing of facial expressions by age 7 months,” Peltola said.

The emotions conveyed by facial expressions are an important part of infant-parent interaction from childbirth onwards. Another area of interest in the Neuroscience Research Programme is how inherited differences impact the development of perceptual functions in infants. Likewise, scientists in the programme are interested in interindividual variation in mother-child interaction.

The results of the project shed useful new light on emotional reactions related to the perception of human faces and how they develop. Furthermore, the project will help to increase understanding of the development of perceptual functions that are crucial to normal social interaction.

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
