Nociceptors are pain receptors, while the other options are receptors for different sensory modalities.

Transduction is the initial step in sensory processing, where physical stimuli are converted into neural signals by sensory receptors.

Psychophysics is the branch of psychology that investigates the relationship between physical stimuli and sensory experiences.

Red, green, and blue are the primary colors of light, while magenta is a secondary color.

Sound localization is the ability to determine the direction and distance of a sound source.

Olfactory receptors are located in the nasal cavity and are responsible for the sense of smell.

Gustatory receptors are located on the tongue and are responsible for the sense of taste.

Tactile receptors are located in the skin and are responsible for the sense of touch.

Attention is the process of filtering and selecting sensory information to focus on specific stimuli.

Adaptation is the process by which sensory receptors become less responsive to a constant stimulus over time.

The absolute threshold is the minimum amount of energy required for a stimulus to be detected.

The difference threshold is the smallest difference between two stimuli that can be detected.

Weber's law states that the just noticeable difference between two stimuli is a constant proportion of the original stimulus.

Fechner's law states that the perceived magnitude of a stimulus is proportional to the logarithm of the physical intensity of the stimulus.

Signal detection theory is a model that predicts the ability of an observer to detect a signal in the presence of noise.
