No life can emerge in chaos - for life to emerge the environment has to be orderly. Organisms have to adapt to their environment, meaning optimise (or satisfice) output in light of input. In a patternless environment, there is no chance doing so. Our brain evolved in light of this - we constantly learn and update what the "norm" is - let it be there's light ...

First, in the context of your reference to cultural context, one aspect of your question appears to be whether or not a person who has never had experiences of triangles before can have a triangle experience. Second, it is of interest whether that experience can be brought about by a configuration of shapes which is considered appropriate to elicit the ...

I think that illusory contours could be experienced independently of cultural influence: a person would see a figure but she would not know it is a "triangle". The reason is that illusory contours as the ones you see in the figure share many of their properties with illusory phenomena that could be obtained with simple alignments of image features. As such, ...

This question cannot be answered in the form in which you asked it both because of the limits of current neuroscientific theories and methodologies when it comes to determining the structures of complex neural representations (although we have made headway in a few cases such as place cells and grid cells), and because neural representations are not really ...

It's a difficult question to answer. My educated guess is that the appearance of the triangle, and illusionary contours in general, would persist, even in individuals who have never seen a triangle before in their lives. I think they would perceive the illusionary contours, but it might just not make sense to them, as the shapes may be unfamilair to them. In ...

Background A dictionary definition of Stereoscopic is the following: [N]oting or pertaining to three-dimensional vision or any of various processes and devices for giving the illusion of ...

Short answer Symptoms of hemi-neglect are often accompanied by additional layers of cognitive deficits that make rehabilitation challenging. Logic reason is often dissociated from these patients' perceptions, or they simply dismiss there is a problem altogether. Background Hemineglect is the impaired or lost ability to react to, or process sensory stimuli ...

My short answer would be that there is no clear relationship between these two models about how visual information processing works in the brain. However, the terminology and evidence overlaps considerably which makes this confusing. One way to think about this is that the two models are explaining different stages of processing. The two visual streams is ...

Short answer In the case of simple stimuli, visual and auditory stimuli can be offset between 25 and 50 ms and still be perceived as coming from one and the same same event. Background The question can be re-phrased as what is the window of integration of intersensory asynchrony in case of visual and auditory stimuli? A well-known example where these two ...
