Sensory Processes and Perception Theories Quiz

Olfaction is the sense of smell, detecting chemical stimuli in the form of odors.

Tolerance is the adaptation to a drug, requiring higher doses over time for the same effect.

Depth perception is the ability to perceive the relative distance of objects in a three-dimensional space.

Absolute threshold is the minimum stimulation required to detect a particular stimulus.

Somatosensation is the sense responsible for detecting pressure, touch, vibration, temperature, and pain.

The trichromatic theory proposes that there are three types of color receptors in the eye, responsible for perceiving different wavelengths of light.

Proximity is the Gestalt principle where objects close together are perceived as a cohesive group.

Place theory proposes that different frequencies of sound activate specific areas on the cochlea, contributing to our perception of pitch.

Closure is the Gestalt principle of mentally filling in gaps to perceive a complete object or scene.

The Cannon-Bard theory posits that physiological arousal and emotional experience happen simultaneously, rather than one causing the other.

B.F. Skinner proposed the theory of operant conditioning, focusing on the influence of consequences on behavior.

Gestalt psychology proposes that the brain processes sensory information as a whole, emphasizing holistic perception over individual components.

Ivan Pavlov proposed the theory of classical conditioning, demonstrating the association between a neutral stimulus and a reflexive response.

Opponent-process theory proposes that color perception is based on opposing neural processes, such as red-green and blue-yellow.

Continuity is the Gestalt principle that involves grouping elements to form continuous lines or patterns in our perception.

The gate-control theory of pain was proposed by Ronald Melzack and Patrick Wall, suggesting a neural 'gate' controls the perception of pain.

Difference threshold is the smallest detectable difference between two stimuli.

Donald Broadbent proposed the theory of selective attention, focusing on the brain's ability to prioritize certain stimuli while ignoring others.

Sensory adaptation is the process where sensory receptors adjust and become less responsive to constant stimuli over time.

Similarity is the perceptual principle of grouping similar elements together in our perception.

Ewald Hering proposed the opponent-process theory, suggesting that color perception is based on opposing neural processes.

Selective attention is the brain's ability to focus on specific sensory inputs while filtering out others.

Perceptual constancy is the tendency to perceive objects as stable and unchanging, even when sensory input varies.

Jerome Bruner proposed the concept of perceptual set, emphasizing the influence of expectations and past experiences on perception.

Perception is the brain's interpretation of sensory information, shaping our conscious experience of the world.
