AP Psychology Unit 4A vocab

occurs when sensory receptors and the nervous system receive stimulus energies from our environment(The skin may detect heat, the eyes may note changes in light, the ears recognize sound, etc.)

• Psychophysics

• Hue

• Sensation

• Transduction

the study of relationships between the physical characteristics of stimuli, such as their intensity, and our psychological experience of them.

• Optic Nerve

• Retina

• Psychophysics

• Transduction

the distance from the peak of one light or sound wave to the peak of the next.

• Feature Detectors

• Lens

• Fovea

• Wavelength

the process that occurs in the brain of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events.

• Hue

• Parellel Processing

• Perception

• Seletive Attention

at the point the optic nerve leaves the eye, there are no receptor cells creating an area where there is not sight

• Lens

• Hue

• Pupil

• Blind Spot

failing to notice modifications in the environment

• Change Blindness

• Fovea

• Inattentional Blindness

• Optic Nerve

a ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening.

• Retina

• Iris

• Cones

• Hue

the dimension of color that is determined by the wavelength of light; what we know as the color names blue, green, and so forth.

• Perception

• Hue

• Psychophysics

• Sensation

transforming of external stimulus energies, such as sights, sounds, and smells into electrical neural impulses our brains can interpret and process; conversion of one form of energy into another.

• Sensation

• Fovea

• Psychophysics

• Transduction

retinal receptor cells that are concentrated near the center of the retina and that function in daylight or in well-lit conditions. The cones detect fine detail and give rise to color sensations.

• Transduction

• Rods

• Iris

• Cones
