What are hit and false alarms, and how are they used in signal detection theory to seperate the experiment participants sensitivity to signals from the response bins of that participants?

Hits occur a signal is presented and the observer detects it. A false alarm occurs if no signal is presented and the observer detects it. The participant's sensitivity to the signals is usually computed by comparing hit rate with the false alarm rate, thus correcting for any bias the participant might bring to the testing situation.

Three pyschological deminsions of color.

three demisions of color consist of hue, brightness, and saturation. Hue is the distinctive characteristics that place particular colors in the spectrum. brightness is the color's perceived inensity or luminance. Saturation tells whether the color is a pure color or not.

Receptors for sound and how are they activated

hair cells in the ear are the primary audotory receptors. the oval window's vibration createpressure waves in the inner ear's fluid. theses waves prompt the hair cells to bend and cause neurons on the basilar memrane to fire.

Concept of different threesholds

different threeshold is just noticeable difference between two stimuli- the minimum amount of change required for a person to detect a difference. like the sound change from a television show and the transittion to a television commercial.

the process of transduction

transduction is a process in which sensory recptors produce neural impulse when they receive physical or chemical stimulation.
