What is the difference between sensation and perception?

What is transduction in the context of sensory systems?

Which process involves assembling sensory signals into something meaningful?

What role does the brain play in sensory systems?

Which part of the ear converts sound vibrations into electrical signals?

Which part of the ear collects sound waves and funnels them into the ear canal?

What is responsible for enabling pitch perception in the ear?

What is responsible for maintaining balance through the vestibular system?

Where are odors detected by olfactory neurons processed?

What is the term for the smallest amount of stimulus change that we can detect?

Which theory explains how we detect stimuli under uncertain conditions?

What does Weber's Law state?

What is the term for our expectations influencing what we perceive?

What is the term for failure to detect obvious changes in the environment?

Which part of the eye changes curvature for accommodation and focuses light onto the back of the eye?

What is the term for the hole where light enters the eye?

What substance dilates the pupil?

What does absolute threshold refer to?

What is parallel processing in sensation and perception?

Which part of the eye is responsible for acuity or sharpness of vision?

What is the process called when the eye adapts the focusing power of the lens based on the distance of objects?

What occurs in hyperopia (far-sightedness)?

What is responsible for transmitting visual information from the retina to the brain?

Which type of depth cues include relative size, texture gradient, and interposition?

What is responsible for basic shapes and forms of objects in dim light?

What is the sense that involves sound vibrations and sound waves?

What determines the pitch of sound?

Which part of the eye contains cell-receptors for vision and neurons?

What begins in infancy and is essential for crawling?

Which illusion involves misperceptions such as the moon illusion and Ames Room illusion?

What occurs when images are focused in front of the retina or when the eyes are too long?

Perception is the detection of physical energy by sense organs.

Transduction is the process of converting external stimulus into neural activity.

Sensory systems translate physical signals into meaningful information for the brain.

The brain's interpretation of raw sensory data is known as sensation.

Vestibular system is responsible for detecting rotational movement of the head

Sensory hair cells in the vestibular system transmit signals to the cerebellum to catch our balance when falling

Awareness of balance occurs only when balance is lost or there are dramatic mismatches between visual input and vestibular inputs

Deafness can only result from damage to the ear itself, and not from the auditory nerve or auditory cortex.

The basilar membrane in the cochlea is responsible for transducing sound vibrations into electrical signals.

Our body only has two types of senses: somatosensory and vestibular.

The gustatory cortex is responsible for processing taste, while the olfactory cortex processes smell.

Humans can detect over 2000-4000 different tastes and a few distinct odors.

Phantom limb syndrome is a condition where amputees feel sensations and pain in their missing limbs.

The somatosensory system is processed in the spinal cord, thalamus, and somatosensory cortex.

Pain sensation can only be thermal or mechanical, and is not affected by hair color.

Proprioception helps us maintain body position and move efficiently.

Supertasters have an undersensitive response to certain tastes, due to a scarcity of taste buds.

Babies can recognize their mothers and siblings based on their odors.

The body senses work independently and do not interact to help us navigate the world.

Cones are responsible for basic shapes and forms of objects in dim light, while rods provide color vision and are sensitive to detail.

The fovea is a large area of the retina responsible for acuity or sharpness of vision.

Binocular depth cues include binocular disparity and binocular convergence.

Perception can never be deceiving, as our senses always accurately represent the world around us.

Motion perception occurs when the brain compares visual frames to determine motion.

Sound pitch is determined by the amplitude of the sound waves.

Myopia occurs when images are focused in front of the retina or when the eyes are too long.

The optic nerve is responsible for transmitting visual information from the retina to the brain.

Monocular depth cues include relative size, texture gradient, interposition, linear perspective, height in plane, and light and shadow.

The retina contains only rods, which are responsible for basic shapes and forms of objects in dim light.

The vestibular system is responsible for catching our balance when falling.

Depth perception begins in adolescence and is not essential for crawling.

Signal-to-Noise Ratio refers to the fact that it becomes easier to detect a signal as background noise increases.

Perceptual constancy means that we perceive a stimulus consistently across varied conditions.

Primary colors for additive color mixing are red, green, and blue.

The cornea is a transparent layer that does not focus light on the back of the eye.

Weber's Law states that the stronger the stimulus, the greater change needed to detect.

Hue refers to the intensity of the reflected light.

Our brains do not rely on what's in our sensory field but also on what was there a moment ago and what we remember from our past.

The fixed lens of the eye changes curvature for accommodation and focuses light onto the back of the eye.

Cocktail Party Effect refers to the fact that we typically notice what other people are saying at a party unless it's relevant to us.

The pupil is the hole where light enters the eye.

Melanin and lipochrome control the amount of light that enters the eye.

Belladonna is a substance that contracts the pupil.
