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 ...

I am a bit amazed, but there is, at least for scent as a memory retrieval cue: Aggleton and Waskett (1999): This study determined the extent to which re-exposure to the unique combination of odours present in a museum (the Jorvik Viking Centre in York) aids the recall of a previous visit to the museum, which had typically taken place several years ...

The most well known sensory after effect illusion in the auditory system is probably the Zwicker tone (Zwicker, 1964). If a white noise with a half‐octave‐band suppression placed anywhere from 300 to 7000 Hz is presented at an over‐all sound‐pressure level of about 60 dB for 1 min and then switched off, a decaying, poststimulatory sound similar to a pure ...

There is some cool evidence (e.g., Canlon et al. 1988) that low level noise exposure can actually protect you against high level noise exposure. That said, I am not sure that one should constantly expose themselves to low level sounds in the hope that it will protect them from high level sounds. Melamed et al. (1996) found that long term exposure to moderate ...

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.

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 ...

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 ...

There are two sound pathways by which we hear: bone conduction and air conduction. The air conduction pathway involves vibrations in the air being transmitted from the ear drum, through the bones of the middle ear, which act as a lever, to our fluid filled inner ear. The lever acts as an impedance matcher between the air and fluid filled inner ear. It ...
