Short answer Yes, continuous exposure to white noise affects neural responses in the auditory system. First, it can alter the tonotopic map in the auditory cortex. Second, it can lead to reduced responsiveness of the auditory thalamus. Background Note: this answer is based on animal experiments using extreme conditions, namely a continuous noise ...

Short answer In practice, absolute pitch is generally tested for by using musical pitch classes. Background Absolute pitch (AP) is the ability to identify the pitch of a musical tone, or to produce a musical tone at a given pitch without the use of an external reference pitch. Most humans process musical pitch relatively rather than absolutely, and in fact ...

The difference is in whether the animal has voluntary control over the touch. If the animal touches another object by moving its body to initiate the touch, then the it is active touch. If the animal is touched without control over the movement (for example, a human experimenter grazing the whiskers with a finger), then the touch is passive.

This is a really neat question. A strong predictor of cognitive ability is one's environmental enrichment, or the stimulation of the brain in its physical and social surroundings. Those with sensory deprivation often have less success with social situations and self-esteem, as well as (presumably) less sensory input coming in. The implication is that lack ...

It can be either, and is typically both, considering that Absolute pitch is an act of cognition, needing memory of the frequency, a label for the frequency (such as "B-flat"), and exposure to the range of sound encompassed by that categorical label. Another way to look at it is that pitch class came from the necessary assessment and organization of ...

It was not an assumption; it was a decision. It allowed for better quantification, it gave an operational definition in increase in sensation, which allowed for more common ground in research between different labs. In a way, it's a definition by pure counting: when the subject feels a change in sensation, add one. Then this absolute scale is plotted against ...

I am currently reading a book called "Snoop", written by researcher Sam Gosling (I recommend this very interesting book!). He's doing just the kind of research I am looking for, and thus I've found tons of research documents on these things: Our research focuses on the following issues: Everyday manifestations of personality – Which cues are ...

Those responding make some very good points about being specific about operational definitions and such. However, I've argued -- in an evolutionary psych textbook -- that there is a probably a reason why discomfort from cold and electric shock have power laws with exponents greater than perceived brightness (at low stimulus intensities), for example. It's ...
