The part of the occipital lobe that contains the primary visual cortex. What takes place when many sensors in the body convert physical signals from the environment into encoded neural signals sent to the central nervous system. A structure in the inner ear that undulates when vibrations from the ossicles reach the cochlear fluid. A listener's experience of sound quality or resonance. Aspects of a scene that yield information about depth when viewed with only one eye. A location in the visual field that produces no sensation on the retina. Sensitivity to prolonged stimulation tends to decline over time as an organism adapts to current conditions. Feeling of pain when sensory information from internal and external areas converges on the same nerve cells in the spinal cord. The ability to see fine detail. The organ of taste transduction. Photoreceptors that detect color, operate under normal daylight conditions, and allow us to focus on fine detail. The minimal intensity needed to just barely detect a stimulus in 50% of the trials. The response to a stimulus depends both on a person's sensitivity to the stimulus in the presence of noise and on a person's response criterion. Photoreceptors that become active under low- The process by which different frequencies stimulate neural signals at specific places along the basilar membrane, from which the brain determines pitch. The process by which the eye maintains a clear image on the retina. How high or low a sound is. A sound's intensity. An area of the retina where vision is the clearest and there are no rods at all. The inability to recognize objects by sight. A fluid- The organization, identification, and interpretation of a sensation in order to form a mental representation. When people fail to detect changes to the visual details of a scene. Light- Methods that measure the strength of a stimulus and the observer's sensitivity to that stimulus. The minimal change in a stimulus that can just barely be detected. Specialized auditory receptor neurons embedded in the basilar membrane. A perceptual mistake where features from multiple objects are incorrectly combined. The active exploration of the environment by touching and grasping objects with our hands. The cochlea registers low frequencies via the firing rate of action potentials entering the auditory nerve. Biochemical odorants emitted by other members of its species that can affect an animal's behavior or physiology. The three fluid- A theory of pain perception based on the idea that signals arriving from pain receptors in the body can be stopped, or gated, by interneurons in the spinal cord via feedback from two directions. The idea that focused attention is not required to detect the individual features that comprise a stimulus, but is required to bind those individual features together. The perception of movement as a result of alternating signal sappearing in rapid succession in different locations. A brain structure located above the nasal cavity beneath the frontal lobes. A portion of the temporal lobe that contains the primary auditory cortex. How features are linked together so that we see unified objects in our visual world rather than free- Simple stimulation of a sense organ. A failure to perceive objects that are not the focus of attention. The difference in the retinal images of the two eyes that provides information about depth. The just noticeable difference of a stimulus is a constant proportion despite variations in intensity. |
