| What is Emmetropia? | show 🗑
|
||||
| show | When you can see objects clearly when they are close, but not when they are far away (nearsighted).
Lens is thick and round.
Varies in severity
🗑
|
||||
| show | When you can see objects clearly when they are far away but not close up (farsighted).
Recessive, eyeball is too short.
Some kids mature out of it.
Lens is thin and flat.
🗑
|
||||
| What are some other issues with seeing clearly? | show 🗑
|
||||
| show | Objects themselves are not colored.
Wavelengths of objects bounce off and into our eyes.
🗑
|
||||
| How does top-down processing influence perception? | show 🗑
|
||||
| show | Trichromatic Theory and Process Theory
🗑
|
||||
| show | When 3 different cones in the eye are responsible for transducing different wavelengths of light.
1. s-cone: short wavelengths, blue light
2. m-cone: medium wavelengths, green light
3. l-cone: long wavelengths, red light
🗑
|
||||
| show | All cones are being equally activated.
🗑
|
||||
| show | Sensory neurons have different activations.
🗑
|
||||
| How do we see black? | show 🗑
|
||||
| What happens when someone is colorblind? | show 🗑
|
||||
| show | The Opponent Process theory (Brain), is when color neurons pair up. 1 is active and 1 is supressed.
COLOR PAIRS: Black and White.
🗑
|
||||
| show | Color you experience after you have been exposed to another color you were exposed to.
Neurons that were not active during the before after you see them active.
Example: after getting your picture taken, you see the dots.
🗑
|
||||
| Contrast of colors and the opponent process theory. | show 🗑
|
||||
| Color blindness doesn't mean all colors are invisible. | show 🗑
|
||||
| show | Your ability to recognize something is 3D.
Distance between ourself and objects in the environment.
Example: Walking up the stairs and knowing how high the step is in space to walk.
🗑
|
||||
| show | Work with one or both eyes open, but only need one open to read cues.
1. Motion Parallax: rate of speed/motion when things seem to be moving faster we percieve them as closer and vice versa.
Example: When moving in a car.
🗑
|
||||
| show | Linear Perspective: placement of parallel lines. Convergence when they come together, the further away they are. Do not have to be straight lines.
Example: standing on railroad tracks and looking into the distance.
🗑
|
||||
| What is the third monocular cue? | show 🗑
|
||||
| What is the fourth monocular cue? | show 🗑
|
||||
| What is a binocular cue? | show 🗑
|
||||
| show | Talking about differences. Between the two retinal images. Light falling on retina in right eye is different than light falling on retina in left eye.
🗑
|
||||
| The fovea tends to focus on the same object, to make it appear clearer. | show 🗑
|
||||
| show | More disparity makes objects appear closer (less overlap).
Less disparity makes objects appear farther (more overlap).
Example: closing one eye and placing your thumb and then closing the other eye. Your thumb moves.
🗑
|
||||
| show | Brain uses disparity to make judgements about distance.
Allows us to see the world in 3D.
Allowing us to make the best judgements about distance.
Providing different wavelengths of light.
🗑
|
||||
| show | Learning is any prolonged or stable change due to experience.
Due to behaviors and MP's
Has to last for a decent amount of time..
Affects how we perveive, remember, think and behave, and future thinking/behaving.
🗑
|
||||
| What is an example of learning? | show 🗑
|
||||
| show | Behavioral Psychologists and Cognitive Psychologists.
🗑
|
||||
| show | When studying learning, they are interested in how we create associations.
Primarily focused on external events or behaviors.
🗑
|
||||
| show | When studying learning they are interested in our mental processes. Thinking, knowing, problem solving.
How do thoughts, feelings, social experiences change us?
Memory and past information.
Want to understand why people behave the way they do.
🗑
|
||||
| show | Ways to make associations, making connections among information.
🗑
|
||||
| What is classical conditioning? | show 🗑
|
||||
| show | Pairing a neutral stimulus (no response), with a reflex, (stimulus and response).
Repeatedly exposures to this pairing leads to learning.
Example: Cat Being Sprayed Experiment.
cat, blinking, sprayed with water.
🗑
|
||||
| What is the result of classical conditioning? | show 🗑
|
||||
| What is Instrumental Conditioning? | show 🗑
|
||||
| show | Behavior results in the addition or removal of a stimulus (consequence).
🗑
|
||||
| Increase behavior=addition/removal is DESIRED | show 🗑
|
||||
| Decrease behavior=addition/removal is UNDESIRED | show 🗑
