Is face perception domain-specific?
Is face perception domain-specific?
Face processing is likely to be domain-specific according to the criteria of common use and origins, because for almost all humans (and probably also for their primate ancestors), faces are the primary if not the only stimulus category for which we are experts at making within-category discriminations.
Is the FFA face specific?
The image shows increased blood flow in cerebral cortex that recognizes faces (FFA). The fusiform face area (FFA, meaning spindle-shaped face area) is a part of the human visual system (while also activated in people blind from birth) that is specialized for facial recognition.
Are faces special in visual processing?
As regard with functional specialization, evidence from adults’ studies has shown that faces are special and are processed in a more holistic or configural way than objects (Tanaka and Farah, 1993; Farah et al., 1998; but see also Robbins and McKone, 2007).
What is the meaning domain-specific?
domain-specific (comparative more domain-specific, superlative most domain-specific) (computing) dedicated to a particular problem domain, a particular problem representation/solution technique.
What is face specificity?
According to the face-specificity hypothesis, the FFA is specialized for face processing. Greater FFA activation to faces than Lepidoptera, another homogeneous object class, occurred during both free viewing and individuation, with similar FFA activation to Lepidoptera and common objects (Experiment 1).
What area of the brain recognizes faces?
temporal lobe
The ability to recognize faces is so important in humans that the brain appears to have an area solely devoted to the task: the fusiform gyrus. Brain imaging studies consistently find that this region of the temporal lobe becomes active when people look at faces.
What is the fusiform face area used for?
The fusiform face area (FFA) is a region of the cortex in the inferior temporal lobe of the brain that has been shown to respond most strongly to faces compared with other types of input (e.g., objects) for typically developing individuals.
What is special about face perception?
There is growing evidence that face recognition is “special” but less certainty concerning the way in which it is special. A selective attention paradigm and a masking paradigm were used to compare the perception of faces with the perception of inverted faces, words, and houses.
Why should we study the visual perception of faces?
Face perception serves as the basis for much of human social exchange. Diverse information can be extracted about an individual from a single glance at their face, including their identity, emotional state, and direction of attention.
How is a specific person’s face represented by the nervous system?
A specific person’s face is represented in the nervous system by the firing of: a group of neurons each responding to a number of different faces.
What did Nancy Kanwisher discover?
One of her discoveries was that the short-term memory drops the second occurrence of a word in a sentence or a picture in a series of images. Kanwisher was also one of the first to use functional magnetic resonance imaging (fMRI) to understand the functional organisation of the brain.
Which is an example of domain specificity in face recognition?
Evidence for domain-specificity Many behavioral studies suggest that domain-specific mechanisms are involved in processing faces. For example, face recognition is more disrupted by inversion (turning the stimulus upside down) than is object recognition3.
How is face perception mediated by neural mechanisms?
Evidence that face perception is mediated by special cognitive and neural mechanisms comes from fMRI studies of the fusiform face area (FFA) and behavioral studies of the face inversion effect. Here, we used these two methods to ask whether face perception mechanisms are stimulus specific, process specific, or both.
Is the face recognition hypothesis a domain general hypothesis?
However, according to a widely discussed alternative hypothesis, face recognition is instead performed by mechanisms specialized for processing any object class for which an individual has expertise. Faces, according to this domain-general hypothesis, are just one example of an expert class.
Is the configural processing involved in face perception?
Here we test the widespread view that face perception critically involves configural processing, that is, the precise distances among face parts Freire et al. 2000, Le Grand et al. 2001, Mondloch et al. 2002, Rhodes et al. 1993.
