|---|---|
| Sensation | When specialized receptors in the sense organs are activated |
| Perception | Organizing and interpreting sensory information into something meaningful |
| Sensory Adaptation | Diminished sensitivity as a consequence of constant stimulation |
| Sensory Interaction | When one sense influences another |
| McGurk Effect | |
| Parallel Processing | Processing several aspects of a problem simultaneously |
| Absolute Threshold (Fechner) | Minimum stimulation needed to detect a stimulus 50% of the time |
| Difference Threshold | Minimum difference between two stimuli required for detection 50% of the time |
| Weber's Law | To be perceived as different, two stimuli must differ by a constant minimum percentage |
| Subliminal | Below the absolute threshold for conscious awareness |
| Prosopagnosia | Face blindness |
| Priming | Activation of associations |
| Top-Down Processing | Using past experiences to organize things into a perception |
| Bottom-Up Processing | Analyzing small features to build up a perception |
| Transduction | Conversion of one form of energy into another |
| Signal Detection Theory | Predicting how and when we detect the presence of a stimulation amid background stimulation |
| Parapsychology | Study of paranormal |
| Feature Detectors | Cells that respond to the features or movement of a stimulus |
| Amplitude | Height of a wave |
| Wavelength | Length of one whole wave (Color) |
| Opponent Process Theory | Information is analyzed into three sets of opponent colors |
| Young-Heimholtz Theory | Retina contains three types of cones: Red, green, and blue |
| Blindsight | When blind people can see movement |
| Blindspot | Point inside the eye where the optic nerve leaves the eye, so there's no rods and cones |
| Accommodation | When the eye lens changes shape to focus near or far objects on the retina |
| Audition | The sense or act of hearing |
| Amplitude (Hearing) | Loudness measured in decibels |
| Wavelength (Hearing) | Frequency measured in hertz |
| Place Theory | Different sound waves trigger different parts of the membrane |
| Frequency Theory | All parts of the membrane are effected and its effected by the frequency of the sound waves |
| Auditory Canal | Earhole |
| Timpanic Membrane | Eardrum |
| Ossicles | Hammer, anvil, and the stirrup |
| Cochlea | Fluid filled membrane |
| Bassalar Membrane | Runs through the cochlea and contains cilia |
| Conduction Hearing Loss | Mechanical; damage to eardrum or ossicles |
| Sensorineural Hearing Loss | Damage to cilia |
| Auditory Localization | Location of a detected sound |
| Phantom Limb | When you still feel a limb after you've lost it |
| Kinesthetic System | Your sense of movement and body parts |
| Vestibular System | Monitors your heads position and movement |
| Nociceptors | Detect cold, heat, pain, and chemicals. Release Substance P |
| Gustation | Sense of taste |
| Gestalt Psychology | The whole is the sum of the parts |
| Closure | Tendency to inclose or complete figures that are incomplete |
| Continuity | Tendency to see continuous figures |
| Similarity | Tendency to group objects that are similar |
| Constancy | Perceiving objects as unchanged |
| Interposition | When one object overlaps another |
| Linear Perspective | Parallel lines appear to converge into the horizon |
| Retinal Disparity | Difference between two images on each retina; the greater the disparity, the closer the object |
| Perceptual Set | Predisposition to perceive things a different way because of previous experiences and expectations |
| Visual Capture | |
| Perceptual Adaptation | Ability to adjust to an artificially displaced visual field |
| Convergence | Both eyes focus on a single object |
