Cognition Flashcards
(130 cards)
1
Q
Internal factors (Perception)
A
Attention, expectations, and emotions can influence how we perceive based on past experiences.
Ex - Someone afraid of dogs may see a friendly dog as a threat.
2
Q
External Factors (Perception)
A
External factors like recognizing a traffic sign, involve processing sensory input to form immediate perceptions.
3
Q
Cocktail Party Effect
A
Refers to our ability to selectively attend to a single conversation in a noisy environment, like a crowded party, even with multiple conversations happening simultaneously.
4
Q
Principle of Figure-Ground
A
Refers to how people segment visuals into two components: figure and ground. The figure is the object or person that is the focus and the ground is the background. This results in the interpretation of different images.
Ex - 2 face one vase
5
Q
Principle of Proximity
A
Suggests that we tend to see closed-set objects as being in a group.

6
Q
Principle of Similarity
A
Theorizes that we mentally group objects that look alike.
Ex - You see alternating rows rather than a block of symbols.
. . .
< < <

< < <
7
Q
Principle of Continuity
A
We perceive objects arranged in continuous lines or curves as more related than elements on a jagged or broken line.
Ex - Seeing two overlapping lines, not four meeting in the middle in the letter X.
8
Q
Principle of Closure
A
States that even if an image is missing parts, your brain will fill in the blanks and perceive a complete image.
9
Q
Principle of Connectedness
A
Proposes that visually-connected objects are more related than objects with no connection.
Ex - We see square-circle pairs as more strongly related because the line visually connects them.
10
Q
Selective Attention
A
The cognitive process by which our awareness focuses on a specific aspect of our environment, like a spotlight.
11
Q
Inattentional Blindness
A
It can significantly impact our perceptions by causing a type of “blindness” to certain aspects of our environment.
12
Q
Change Blindness
A
A common occurrence stemming from inattention, where changes in the environment go unnoticed. When our attention is focused elsewhere, we may experience inattentional blindness, leading us to overlook visible objects.
13
Q
Depth Perception
A
Our ability to see objects in three dimensions (Images are 2-d when they strike the retina). Helps judge distances and is crucial for out survival skills, like avoid falling off a cliff.
14
Q
Binocular cues
A
Allows to see depth by using both eyes.
15
Q
Retinal (Binocular) Disparity
A
States that our brain receives two different images since our two eyes are a few inches apart. When the two images are quite different, we see them as being close to us, and the opposite for two same images.
16
Q
Convergence
A
It states that as an object gets closer to us, we must strain our eyes to stay focused on it. So, the more significant the muscle strain, the closer the object is to us.
17
Q
Monocular Cues
A
Depth cues that depend on one eye.
18
Q
Relative Clarity
A
Objects that appear clearer and more detailed are perceived as being closer, while blurry images are seen further away.
19
Q
Interposition
A
If overlap or one image blocks another, it is perceived as closer.
20
Q
Relative Size
A
if we know that two images are around the same size, the smaller one is perceived as further away.
21
Q
Texture Gradient
A
As texture extends into the background, it becomes hazy or less clearly defined.
22
Q
Relative Height
A
Objects higher in our visual field are perceived as further away.
23
Q
Relative Motion (Motion Parallax)
A
Closer objects appear to move more quickly.
24
Q
Linear Perspective
A
Parallel lines converge with distance into a vanishing point.
25
Stroboscopic Movement
When we view a film, our brain seamlessly combines a rapid succession of slightly different images into continuous movement, rather than perceiving individual frames.
26
Phi Phenomenon
When two stationary lights flicker rapidly, our brain merges them into a single light moving back and forth.
Ex - observing a series of synchronized fireworks in the night sky that create the illusion of a dancing dragon
27
Autokinetic Effect
Highlights how fixating on a stationary light in a dark room can cause it to seem in motion due to our natural eye movements.
28
Perceptual Constancy
It involves recognizing objects without being deceived by changes in their color, brightness, shape, or size, regardless of the viewing angle, distance, making it possible to make quick and accurate judgments.
29
Color Constancy
Where we perceive familiar objects as having consistent color regardless of changes in illumination that may alter the wave-lengths reflected by the object.
Ex - We see a ripe banana as yellow whether it is under bright sunlight or artificial indoor lighting.
30
Brightness Constancy (Lightness Constancy)
Allows us to perceive an object as having constant brightness even as the lighting conditions around it change.
Ex - We can recognize a white shirt as white whether it is in dim lighting or bright daylight.
31
Shape Constancy
Allows us to see familiar objects as having a constant shape, regardless of how the images on our retinas change.
Ex - Even as we view a book from different angles, we still recognize it as a rectangular object.
32
Size Constancy
Enables us to perceive an object as maintaining a constant shape, regardless of our distance from it.
33
Perceptual Adaptation
Involves adjusting to changes in sensory input.
Ex - Imagine wearing glasses that flip everything you see upside down. Initially the world around you would appear completely disorienting, but over time, your brain would adapt to the new visual world.
34
Metacognition

36
Schemas
As we grow and learn, our brains create mental frameworks or concepts to make sense of the world around is.

Mood-Congruent Memory
A phenomenon that reflects memory-state dependence, where in emotions experienced during the past events serve as retrieval cues.
99
Interleaving
A learning technique that involves mixing different topics or types of problems within a single study session, rather than focusing on just one type.
100
Encoding Failure
Occurs due to the inability to encode the information into long term memory in the first place.
101
Divided Attention (Absent-mindedness)
If you are not paying attention to info as it is being presented, you will likely forget it.
102
Decay Theory (Storage Decay)
States that we forget memories because we do not use them, and they fade away over time.

Validity (Tests)
In a test means that the test has achieved measuring what it is supposed to measure
129
Evolutionary Perspectives
Suggest that differences in societies where girls excel in spelling, vocab, reading, and object location tasks, may have developed due to the differing roles in historically assigned to men and women, while social expectations and opportunities shape and reinforce these gender distinctions.
130
Stereotype Lift
An increase in a group's test performance due to not being part of a negative stereotype.
Ex - Men might perform better at math tests if they are primed on the stereotype that men are better than women at math.
