Study Notes

Sensation

Sensory receptors are specialized neurons that respond to specific stimuli.
Sensation occurs when sensory information is detected by a sensory receptor.
Transduction is the conversion of sensory stimulus energy into action potentials.
There are more than five senses, including vision, hearing, smell, taste, touch, vestibular sense, proprioception and kinesthesia, pain (nociception), and temperature (thermoception).
Absolute threshold is the minimum amount of stimulus energy needed to be detected 50% of the time.
Sensory receptors can be quite sensitive; for example, the eye can detect a candle flame 30 miles away, under quiet conditions, the hair cells (in the inner ear) can detect a clock's tick from 20 feet away.
Subliminal messages are stimuli below the threshold for conscious awareness.

Perception

Perception is how sensory information is organized, interpreted, and consciously experienced.
It involves bottom-up and top-down processing.
Bottom-up processing is driven by sensory information from the environment.
Top-down processing is driven by knowledge and expectations.
Sensation is a physical process, whereas perception is psychological.
Attention plays a significant role in perception.
Inattentional blindness is the failure to notice something that is completely visible because the person is actively attending to something else.

Anatomy of the Visual System

The eye is the major sensory organ involved in vision.
Light passes through the cornea and pupil, and is focused by the lens onto the retina.
The retina contains photoreceptor cells: cones and rods.
Cones are involved in color vision and high-acuity detail in bright light conditions.
Rods are involved in low-light vision and peripheral vision.
Information from the retina is carried to the brain via the optic nerve.

Anatomy of the Auditory System

The ear has three parts: outer, middle, and inner.
The outer ear collects sound waves.
The middle ear amplifies the sound waves through the ossicles (malleus, incus, stapes).
The inner ear contains the cochlea, which contains sensory receptors (hair cells) on the basilar membrane.
Sound waves cause vibrations in the basilar membrane, which stimulate the hair cells.
Information from the hair cells is sent to the brain via the auditory nerve.

Pitch Perception

Different frequencies of sound waves are associated with different pitches.
Temporal theory suggests that frequency is encoded by the activity level of sensory neurons.
Place theory suggests that different portions of the basilar membrane respond best to different frequencies.

Sound Localization

Localizing sound requires monaural and binaural cues.
Monaural cues are from one ear. This helps with detecting sounds above, below, in front, or behind us.
Binaural cues are from both ears. This helps with detecting sounds to the left, right etc.
Interaural level differences is the difference in sound intensity from each ear.
Interaural timing difference is the difference in time sound reaches each ear.

Hearing Loss

Deafness is the partial or complete inability to hear.
Conductive hearing loss is due to a problem delivering sound energy to the cochlea.
Sensorineural hearing loss is due to damage to the inner ear or auditory nerve.

Chemical Senses

Taste (gustation) and smell (olfaction) are chemical senses.
Taste receptors respond to molecules dissolved in saliva.
Taste buds contain taste receptor cells with extensions that interact with dissolved molecules.
Smell receptors are in the nasal cavity.
Smell and taste information interacts and influences each other.

Depth Perception

Binocular cues: cues that require both eyes.
Monocular cues: cues that require only one eye.
Examples of monocular cues include linear perspective, interposition, and relative size.

Color Vision

Normal-sighted individuals have three types of cones that mediate color vision.
Each cone type is maximally sensitive to a different wavelength of light. This results in the perception of different colors.
Trichromatic theory of color vision explains how colors are produced by combining red, green, and blue.
Opponent-process theory explains why some colors are not perceived (e.g., reddish-green).

Pain Perception

Pain involves both physical and psychological components.
Pain is crucial for signaling injury and preventing further damage and thus has an adaptive function.
Different types of pain exist, such as neuropathic pain and inflammatory pain.
There are a variety of treatments for pain, including medicine, and therapies.

Vestibular Sense, Proprioception, and Kinesthesia

Vestibular sense is involved in balance and body posture.
Proprioception is awareness of body position and movement.
Kinesthesia is perception of body movement and limb position.
All three contribute to our ability to move and interact in our environment.
