Pacinian corpuscles (deep pressure), Meissner corpuscles (touch), Merkle discs (pressure and texture), Ruffini endings (warmth), and fee nerve endings (most common)
Send information to somatosensory cortex in parietal lobe

Q

Selective attention

A

Acts as a filter between sensory stimuli and processing systems.
According to Donald Broadbent, all-or-nothing process (can only attend to one incoming stimulus at a time); more recent research indicates it doesn’t work that way.
Ancillary stimuli are dampened

A

Technique used by psychologists to study selective attention in a lab setting:
The two ears are presented with two different messages and the participant is asked to repeat one of the messages as it is presented; indicates that listeners can attend to one message and dampen the other
