Sensory Systems and Perception: From Stimulus to Understanding
A comprehensive... Show more
This page delves into the concept of thresholds in sensory systems, focusing on absolute thresholds and difference thresholds.
Definition: Absolute threshold is the minimum stimulation necessary to detect a particular light, sound, pressure, taste, or odor 50 percent of the time.
The page provides a table detailing the absolute thresholds for different senses:
Example: For vision, the absolute threshold is a candle flame viewed from about 30 miles away on a dark night.
Signal detection theory is introduced, which predicts when we will detect weak signals. This theory assumes there is no single absolute threshold, and detection depends on a person's experience, expectations, motivation, and alertness.
Vocabulary: Subliminal stimuli are those that cannot be consciously detected 50% of the time, falling below the absolute threshold.
The concept of difference thresholds, also known as just noticeable difference , is explained. Weber's law is introduced, stating that for an average person to perceive a difference, two stimuli must differ by a constant minimum percentage, not a constant amount.
Highlight: The exact percentage for Weber's law varies depending on the stimulus, making it a flexible principle applicable to various sensory experiences.
This page explores sensory adaptation and introduces the concept of perceptual set.
Definition: Sensory adaptation is the diminished sensitivity as a consequence of constant stimulation.
When constantly exposed to an unchanging stimulus, our awareness decreases because our nerve cells fire less frequently.
Example: Putting a bandaid on your arm and eventually not sensing it is a common example of sensory adaptation.
The page introduces the concept of perceptual set, which is a set of mental tendencies and assumptions that affects, top-down, what we perceive.
Highlight: Context, motivation, and emotion play significant roles in shaping our perceptions, influencing how we interpret sensory information.
This section emphasizes the importance of understanding how our past experiences and current mental state can influence our perception of the world around us, highlighting the complex interplay between sensation and perception in the sensory system function.
The third page explores how our senses adapt to constant stimulation and the various factors that influence perception.
Definition: Sensory adaptation is the decreased sensitivity resulting from constant stimulation.
Example: The sensation of a bandaid on your arm diminishing over time demonstrates sensory adaptation.
Highlight: Perceptual set influences how we interpret stimuli through mental tendencies and assumptions.
This section focuses on visual processing and the nature of light as a stimulus.
Definition: Visible light represents a small portion of the electromagnetic spectrum that our visual system can detect.
Example: When viewing a red tulip, we're actually detecting electromagnetic energy that our visual system interprets as red.
Highlight: ESP skepticism centers on the lack of replicable evidence under controlled conditions.
This page details the complex process of visual signal processing and color perception.
Vocabulary: The fovea is the retina's area of central focus where cone cells cluster.
Definition: The Young-Helmholtz trichromatic theory explains color vision through three types of cone cells.
Highlight: The eye has a blind spot where the optic nerve exits, containing no receptor cells.
The sixth page covers depth perception principles and introduces auditory processing.
Definition: Depth perception allows us to see objects in 3D despite receiving 2D retinal images.
Example: The principle of continuity explains why we perceive smooth, continuous patterns rather than discontinuous ones.
Highlight: The principle of closure demonstrates how we mentally complete incomplete visual patterns.
This page explains the mechanics of hearing and sound perception.
Vocabulary: The malleus, incus, and stapes are the three tiny bones in the middle ear.
Definition: The cochlea is a snail-shaped tube in the inner ear crucial for sound processing.
Example: Hair cells in the cochlea respond differently to varying sound intensities.
This page introduces the fundamental concepts of sensation and perception, highlighting the differences between these two processes and their importance in understanding how we interact with our environment.
Definition: Sensation is the process in which sensory receptors detect sensory information, and the nervous system transmits that information to the brain. Perception is the process by which the brain organizes and interprets sensory information.
The page discusses two types of processing:
Highlight: Selective attention plays a crucial role in how we perceive our environment. Our consciousness focuses on one thing at a time, which can lead to inattentional blindness and change blindness.
Example: In an experiment, viewers focused on counting basketball passes often failed to notice a woman with an umbrella walking across the screen, demonstrating inattentional blindness.
The concept of sensory transduction in psychology is introduced as the process of converting one form of energy into another that our brain can use. This process involves specialized receptor cells that receive stimuli, transform them into neural impulses, and deliver this information to the brain.
Vocabulary: Transduction can be thought of as translation or transformation of sensory information.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀
