Document Summary
Chapter 4: galen attributed faculties of the human mind to the brain. 19th century: role of the brain for social interaction; front lobe phineaus gage. Cacioppo social neuroscience; research on social brain". Human faces and bodies are reliably discriminated from other object categories early in the visual processing cascade. Eventrelated brain potentials (erps) indicate that faces, relative to a variety of other objects, elicit an enhanced negative potential at around 170 ms after the onset of a stimulus. Signal is associated with detecting common structural properties of facial stimuli, Bodies, sihouettes, stick figures at 190 ms; all distinguish rapidly in human brain. Perceiving and construing others is accomplished byan extensive and widely distributed neural system of brain regions: two sub systems. Core neural system that accomplishes the structural and motion-related visual analysis of human faces and bodies based on input from early visual brain regions;
