What is the difference between perception and sensation?
So before your perception can occur, which actually is our answer in that sensory info is organized, interpreted and experience consciously, that sensory info must be detected and that occurs in sensation. So, to put it simply, perception is our answer.
What factors affect sensation and perception?
There is another factor that affects sensation and perception: attention. Attention plays a significant role in determining what is sensed versus what is perceived. Imagine you are at a party full of music, chatter, and laughter.
What is the interpretation of sensory information called?
Perception refers to the process of acquiring, interpreting, and representing incoming sensory information.
Where is sensory information consciously interpreted?
All sensory signals, except those from the olfactory system, enter the central nervous system and are routed to the thalamus. When the sensory signal exits the thalamus, it is conducted to the specific area of the cortex dedicated to processing that particular sense.
What happens when sensory information is detected by a sensory receptor?
Sensory receptors are specialized neurons that respond to specific types of stimuli. When sensory information is detected by a sensory receptor, sensation has occurred.
Which type of processing involves the interpretation of sensation?
Bottom-up processing refers to the fact that perceptions are built from sensory input. On the other hand, how we interpret those sensations is influenced by our available knowledge, our experiences, and our thoughts. This is called top-down processing.
What part of the brain interprets sensory information?
The parietal lobe is separated from the occipital lobe by the parieto-occipital sulcus and is behind the central sulcus. It is responsible for processing sensory information and contains the somatosensory cortex.
How does the brain interpret sensory information?
There are seven different types of receptors related to each of the seven senses. Each receptor is responsible for picking up sensory information and passing this information to our brain for processing which involves organising, prioritising, understanding and responding to the information.
What are the types of sensory receptors?
Sensory receptors are primarily classified as chemoreceptors, thermoreceptors, mechanoreceptors, or photoreceptors....Broadly, sensory receptors respond to one of four primary stimuli:Chemicals (chemoreceptors)Temperature (thermoreceptors)Pressure (mechanoreceptors)Light (photoreceptors)
What happens when sensory information is detected by a sensory receptor quizlet?
When sensory information is detected by a sensory receptor, sensation has occurred. For example, light that enters the eye causes chemical changes in cells that line the back of the eye. The sensitivity of a given sensory system to the relevant stimuli can be expressed as an absolute threshold.
What type of process is perception?
Perception is the process of selecting, organizing, and interpreting information from our senses. Selection: Focusing attention on certain sights, sounds, tastes, touches, or smells in your environment. Something that seems especially noticeable and significant is considered salient.
What is the meaning of sensation and perception?
Sensation occurs when sensory receptors detect sensory stimuli. Perception involves the organization, interpretation, and conscious experience of those sensations.
What is sensory perception in psychology?
Sensory perception involves detecting, recognizing, characterizing and responding to stimuli. There are five different kinds of stimulus, they can be categorised as mechanical, chemical, electrical, light and temperature.

What is the first stage in the sensory processing of information?
Sensory memory is the first stage of Information Processing Theory. It refers to what we are experiencing through our senses at any given moment. This includes what we can see, hear, touch, taste and smell. Sight and hearing are generally thought to be the two most important ones.
Which nerve carries visual information from the retina to the brain?
Optic nerve: This cranial nerve sends visual information from your retina to your brain. It consists of more than 1 million nerve fibers.
Why do you see a lemon as yellow?
We see a lemon as yellow because the pigments in the skin of a lemon reflect yellow light. The pigment absorbs all colors of light except yellow. Our eyes can detect the reflected color due to the cones in the retinas.
How we interpret what we experience is called quizlet?
Perception. the process by which our brain organizes and interprets sensory information, transforming it into meaningful objects and events.
What is sensory adaptation?
Sensory adaptation: not percieving stimuli that remain relatively constant over prolonged periods of time.
Which membrane is most sensitive to low frequencies?
Suggest that different portions of the basilar membrane are sensitive to sounds of different frequencies. For example, the base of the basilar membrane responds best to high frequencies and the tip of the basilar membrane responds best to low frequencies.

Only when deafness appears does the distinction between congenital and deaf people specify.
What is the definition of congenital deafness?from oliveunion.com
Explaining Congenital Deafness. Congenital deafness is hearing loss that is present at birth. This hearing loss can either be manifested at birth or develop later, but is the result of genetic causes or other influences that affected the fetus. Relatively rare, congenital hearing loss occurs in approximately one out of every 1,000 to 2,000 births.
What is the purpose of auditory brainstem implants?from oliveunion.com

What is the condition where the sutures between the bones of the skull fuse too early during development?from oliveunion.com
Crouzon syndrome – this rare disorder is a form of craniosynostosis, in which the sutures between the bones of the skull fuse too early during development. This premature fusion affects the development of the skull and head and can prevent the normal transmission of sound, resulting in sensorineural hearing loss.
Why do people have deafness?from oliveunion.com
The majority of congenital deafness or hearing loss cases are due to genetic or hereditary reasons. Both parents may have healthy hearing yet carry recessive genes that cause issues or genetic syndromes in which hearing loss is a symptom. Some examples include:
How is Congenital Deafness Treated?from oliveunion.com
It is recommended that treatment for congenital hearing loss start before the age of six months. At this age, children are beginning to develop communication skills. In order for the child to develop at a similar level to normal hearing children, aids to hearing are crucial.

Failure to notice something that is completely visible because of a lack of attention is called. inattentional blindness. . In a similar experiment, researchers tested inattentional blindness by asking participants to observe images moving across a computer screen.
How does motivation affect perception?
Motivation can also affect perception. Have you ever been expecting a really important phone call and, while taking a shower, you think you hear the phone ringing, only to discover that it is not? If so, then you have experienced how motivation to detect a meaningful stimulus can shift our ability to discriminate between a true sensory stimulus and background noise. The ability to identify a stimulus when it is embedded in a distracting background is called signal detection theory. This might also explain why a mother is awakened by a quiet murmur from her baby but not by other sounds that occur while she is asleep. Signal detection theory has practical applications, such as increasing air traffic controller accuracy. Controllers need to be able to detect planes among many signals (blips) that appear on the radar screen and follow those planes as they move through the sky. In fact, the original work of the researcher who developed signal detection theory was focused on improving the sensitivity of air traffic controllers to plane blips (Swets, 1964).
What is the role of attention in perception?
There is another factor that affects sensation and perception: attention. Attention plays a significant role in determining what is sensed versus what is perceived. Imagine you are at a party full of music, chatter, and laughter.

For example, Marshall Segall, Donald Campbell, and Melville Herskovits (1963) published the results of a multinational study in which they demonstrated that individuals from Western cultures were more prone to experience certain types of visual illusions than individuals from non-Western cultures, and vice versa.
What does it mean to sense something?
What does it mean to sense something? Sensory receptors are specialized neurons that respond to specific types of stimuli. When sensory information is detected by a sensory receptor, has occurred. For example, light that enters the eye causes chemical changes in cells that line the back of the eye. These cells relay messages, in the form of action potentials (as you learned when studying biopsychology), to the central nervous system. The conversion from sensory stimulus energy to action potential is known as transduction.

You have probably known since elementary school that we have five senses: vision, hearing (audition), smell (olfaction), taste (gustation), and touch (somatosensation). It turns out that this notion of five senses is oversimplified.
Is sensation a physical or psychological process?
This is called top-down processing. One way to think of this concept is that sensation is a physical process, whereas perception is psychological. For example, upon walking into a kitchen and smelling the scent of baking cinnamon rolls, the sensation is the scent receptors detecting the odor of cinnamon, but the perception may be “Mmm, ...
Perception
While our sensory receptors are constantly collecting information from the environment, it is ultimately how we interpret that information that affects how we interact with the world. Perception refers to the way sensory information is organized, interpreted, and consciously experienced. Perception involves both bottom-up and top-down processing.
Amplitude and Wavelength
Two physical characteristics of a wave are amplitude and wavelength ( Figure 5.5 ). The amplitude of a wave is the distance from the center line to the top point of the crest or the bottom point of the trough. Wavelength refers to the length of a wave from one peak to the next.
Light Waves
The visible spectrum is the portion of the larger electromagnetic spectrum that we can see. As Figure 5.7 shows, the electromagnetic spectrum encompasses all of the electromagnetic radiation that occurs in our environment and includes gamma rays, x-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves.
Sound Waves
Like light waves, the physical properties of sound waves are associated with various aspects of our perception of sound. The frequency of a sound wave is associated with our perception of that sound’s pitch. High-frequency sound waves are perceived as high-pitched sounds, while low-frequency sound waves are perceived as low-pitched sounds.
Anatomy of the Visual System
The eye is the major sensory organ involved in vision ( Figure 5.11 ). Light waves are transmitted across the cornea and enter the eye through the pupil. The cornea is the transparent covering over the eye. It serves as a barrier between the inner eye and the outside world, and it is involved in focusing light waves that enter the eye.
Color and Depth Perception
We do not see the world in black and white; neither do we see it as two-dimensional (2-D) or flat (just height and width, no depth). Let’s look at how color vision works and how we perceive three dimensions (height, width, and depth).
Anatomy of the Auditory System
The ear can be separated into multiple sections. The outer ear includes the pinna, which is the visible part of the ear that protrudes from our heads, the auditory canal, and the tympanic membrane, or eardrum.
