The science dealing with the correlation of the physical characteristics of a stimulus, e.g., frequency or intensity, with the response to the stimulus, in order to assess the psychologic factors involved in the relationship.

The process by which the nature and meaning of sensory stimuli are recognized and interpreted.

Mental process to visually perceive a critical number of facts (the pattern), such as characters, shapes, displays, or designs.

Investigative technique commonly used during ELECTROENCEPHALOGRAPHY in which a series of bright light flashes or visual patterns are used to elicit brain activity.

The selecting and organizing of visual stimuli based on the individual's past experience.

The real or apparent movement of objects through the visual field.

The perceiving of attributes, characteristics, and behaviors of one's associates or social groups.

The process whereby an utterance is decoded into a representation in terms of linguistic units (sequences of phonetic segments which combine to form lexical and grammatical morphemes).

Perception of three-dimensionality.

The process whereby auditory stimuli are selected, organized, and interpreted by the organism.

The process by which PAIN is recognized and interpreted by the brain.

The ability to estimate periods of time lapsed or duration of time.

A dimension of auditory sensation varying with cycles per second of the sound stimulus.

The process by which the nature and meaning of gustatory stimuli are recognized and interpreted by the brain. The four basic classes of taste perception are salty, sweet, bitter, and sour.

The awareness of the spatial properties of objects; includes physical space.

The process by which the nature and meaning of tactile stimuli are recognized and interpreted by the brain, such as realizing the characteristics or name of an object being touched.

The sensory interpretation of the dimensions of objects.

Mental processing of chromatic signals (COLOR VISION) from the eye by the VISUAL CORTEX where they are converted into symbolic representations. Color perception involves numerous neurons, and is influenced not only by the distribution of wavelengths from the viewed object, but also by its background color and brightness contrast at its boundary.

The process by which the nature and meaning of olfactory stimuli, such as odors, are recognized and interpreted by the brain.

Predetermined sets of questions used to collect data - clinical data, social status, occupational group, etc. The term is often applied to a self-completed survey instrument.

Differential response to different stimuli.

An illusion of vision usually affecting spatial relations.

Sound that expresses emotion through rhythm, melody, and harmony.

An enduring, learned predisposition to behave in a consistent way toward a given class of objects, or a persistent mental and/or neural state of readiness to react to a certain class of objects, not as they are but as they are conceived to be.
