Watch and listen - A cross-cultural study of audio-visual-matching behavior in 4.5-month-old infants in German and Swedish talking faces

Abstract

Investigating infants' ability to match visual and auditory speech segments presented sequentially allows us to understand more about the type of information they encode in each domain, as well as their ability to relate the information. One previous study found that 4.5- month-old infants' preference for visual French or German speech depended on whether they had previously heard the respective language, suggesting a remarkable ability to encode and relate audio-visual speech cues and to use these to guide their looking behavior. However, French and German differ in their prosody, meaning that perhaps, the infants did not base their matching on phonological or phonetic cues, but on prosody patterns. The present study aimed to address this issue by tracking the eye gaze of 4.5-month-old German and Swedish infants cross-culturally in an intersensory matching procedure, comparing German and Swedish, two same-rhythm-class languages differing in phonetic and phonological attributes but not in prosody. Looking times indicated that even when distinctive prosodic cues were eliminated, 4.5- month-olds were able to extract subtle language properties and sequentially match visual and heard fluent speech. This outcome was the same for dif...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
