Abstract:
Research in perception in the visual and auditory domains has traditionally focused on investigating highly controlled artificial stimulus material. However, a key feature of our perceptual system is the ease with which the input of a wide set of naturalistic co-occurring information is dealt with. This study investigated whether, during perception of real-world surface material, a conceptual representation is built that has the potential to interact with a linguistic description of the material directly. Short sentences were presented (e.g., This surface is smooth) followed by a matching or mismatching picture of a real-world surface material. The results showed early cross-modal integration effects during material surface perception in an N400-like potential, originating approximately 280 ms after stimulus presentation. Overall, these findings suggest a rather early influence of linguistic information on material perception, suggesting that in line with object representation, real-world materials are represented in the brain in a format that allows interaction with non-visual information.

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
