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 ...

There is the structured called the Fusiform-face area (FFA), which is located a low tempero-parietal region. In human studies, the FFA has shown to highlight strongly when you look at a human face, as opposed to any other (inanimate) object. This is what the region got its name from. However, it is believed that the FFA is not necessarily a face area (See "...

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, ...

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 ...

Short answer Hair cells in the cochlea can code sound intensity via the amount of neurotransmitter they release. Higher sound levels result in more neurotransmitter release and in turn to higher firing rates in the spiral ganglion cells of the auditory nerve. Background Sound waves are picked up by the mechanoreceptors in the inner ear: the hair cells. ...

Short answer Stereoscopic vision is the perception of depth via disparity. Disparity is the mechanism that the visual system uses to create binocular depth perception. 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 ...

Elliot et al. (2008) define a hallucination as: A sensory experience which occurs in the absence of corresponding external stimulation of the relevant sensory organ, has sufficient sense of reality resemble a veridical perception (i.e. the perception seems to be "real"), over which the subject does not feel direct and voluntary control, and which occurs ...

I never thought that my Bachelor Thesis would ever come in handy. Thank you for this question! Short answer No, you cannot keep up two unrelated rhythms in a stable coordinated fashion when tapping for your finger for instance. Long Answer Let us start with (and skip over) the oldest paper that I have about it. Haken, Kelso and Bunz (1985) described in a ...

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 ...

Pain is a form of stress. I would replace pain with another, ethically less problematic stressor. If you would want to do it elegantly, test a group of subjects with chronic pain (anything; e.g., back pain) and use a control group where you submit a group of healthy subjects to a stress test (e.g. Stroop test - huge body of literature on this) and a third ...

Short answer Females are more sensitive to some, but not all somatosensory stimuli. Males are either less sensitive, or as sensitive as females. Background A normative study by Blankenburg et al. (2010) determined reference values for a battery of somatosensory tests including cold detection threshold (CDT); warm detection threshold (WDT); thermal sensory ...

Objects are visually perceived when they reflect light. A black object does not reflect any light. In other words, no photons are reflected to be detected by the photoreceptors in the retina. A black shape on a colored background appears black because its brightness approaches zero relative to its surroundings. Black, as any other perceived hue, is a ...

Modern Psychology and Philosophy does not say that we detect things, but instead that we have perceptions. It is easy to see an all-black thing in the midst of things that are not black, because it simply looks different, not that it has some special quality of "blackness". In fact, that is how all perception works: difference against a background (of other ...
