No, inner speech does not follow the same neural pathway as speech coming in from outside. Rather, inner speech uses the same neural mechanism as outer speech - that is, speech going out. The neural mechanisms of inner speech can be studied using recently developed technologies such as fMRI imaging of subjects instructed to or prevented from engaging 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. ...

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 ...

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 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 ...

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 ...

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 ...

This is not quite your question, but it's the closest thing I know of. There's a significant amount of work suggesting that purely morphological attributes can shape conceptualization: looking at the impact of grammatical gender on the attributes assigned to the nouns that have a specific grammatical gender--that is, grammatically male nouns are rated ...

There is the structure called the Fusiform-face area (FFA), which is located in the 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 (...

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, ...

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 ...
