New cards

Perception

Involves organizing and interpreting sensory information. Brings meaning to sensation. Primarily influenced on whether one relies on external sensory information or internal prior expectations.

2
New cards

Bottom up processing

Relies on external sensory information. It is information processing of basic elements or features to build perception.

Ex: Learning to drive and learning when to apply the gas and brakes.

3
New cards

Top down processing

Relies on internal prior expectations. It is information processing that involves experience, expectations and motives to fill the gaps to complete a perception.

Ex: you have a bad reception on a phone call but can still make out what the other person is saying

4
New cards

Schema

Top down mental framework for organizing and understanding our world. They help guide our perceptions. Through experiences, we form schemes to organize and interpret our info.

5
New cards

Perceptual set

The readiness to perceive something in a particular way or having an expectation for a stimulus. We see what we expect to see.

Ex: when you were speeding and you see a flashing light, you assume you’re being pulled over.

6
New cards

Gestalt principles

Perceptual principles proposed by Gestalt psychology to help explain how humans organize their perceptual world.

7
New cards

Closure

Gestalt principle of making a hole or completed object by filling in the gaps.

11
New cards

Attention

An interaction of sensation and perception that is affected by internal and external processes

12
New cards

Cocktail party effect

Where people attend to mentions of their names or specific topics and loud and distractive environments

13
New cards

Inattention

Lead to a type of blindness to aspects in the environment

14
New cards

inattentional blindness

Occurs when attention is focused on one part of the visual field and as a result, you may ignore or miss other parts

15
New cards

Change blindness

A specific type of inattentional blindness, occurs when changes in the visual field are not perceived due to inattention or brief interruption

16
New cards

Binocular depth cues

Retinal disparity and convergence. Two eyes to Utilize both cues to provide perception of death.

17
New cards

Retinal disparity

Determining depth based on the difference between what each eye sees

18
New cards

Convergence

Determining depth based on how much both eyes rotate inward

19
New cards

Monocular depth cues

Use one eye to give the illusion of depth on flat or two dimensional surfaces.

20
New cards

The five monocular depth cues

Relative clarity, relative size, texture, gradient, linear perspective, and interposition

21
New cards

Visual perception consistencies

Maintain the visual perception of an object, even when the images of the object objects in the visual field change.

22
New cards

Color constancy

When an object has the same brightness despite the changing amount of illumination

23
New cards

Shape constancy

When an object has the same dimension or shape despite the changing angle or orientation

Forms the mental basis of thought. They are mental groupings based on shared features, and come from experience.

Ex: fruit, dogs, furniture

27
New cards

Prototype

Ideal example of any given concept. What typically comes to mind. An image that represents an example from your experiences.

Ex: fruit makes you think of apples, pears, bananas, but not tomatoes

28
New cards

Schema

Golden blocks of intellectual development that make an organization and meaningful action possible. Schemas provide context

29
New cards

Assimilation

Taking a new information, but not changing the schema because of it. Placing new information into an existing schema.

30
New cards

accommodation

Taking a new information and changing the schema to incorporate the new info. Changing an existing schema or creating a new schema.

31
New cards

Algorithm

Addresses problems by attempting all possible solutions until the correct one is found

Ex: using a formula to solve math problems, instructions for a recipe, or trying all possible lock combinations

32
New cards

Heuristic

Addresses problems by using mental shortcuts to make judgments.

Ex: selecting a restaurant based on the reviews, guessing who’s older is based on height, choosing the best brand based on the price.

33
New cards

Types of heuristics

Representative, availability

34
New cards

Representative heuristic

Lead to an error in judgment in where decisions are made according to prior expectations or stereotypes.

35
New cards

Availability heuristic

lead to an error in judgment where decisions are made by recalling the first or most vivid example that comes to mind

36
New cards

Mental set

Using what worked in the past rather than trying something new

37
New cards

Framing

Alters your decision based on how something is presented to you

38
New cards

Gamblers fallacy

For belief that you can predict a chance event based on past chance events

Ex: you flip a coin and it’s heads five times in a row, you think there is a higher probability of it being tails

39
New cards

Sunk cost fallacy

A bad decision based on time, money, or effort that has already been spent.

Ex: you bought a concert ticket, but you wake up sick that day. You decide to go because you don’t want to waste your money.

40
New cards

Divergent thinking

Considering many different ideas or solutions to a problem. Associated with creativity since someone must break from normal problem-solving and create unusual associations.

41
New cards

Convergent thinking

Using knowledge and logic to narrow down options to find known solution, or single, correct answer.

42
New cards

Implicit memories

“Tell me how to climb a flight of stairs”

Also called declarative memories. Procedural, classically, conditioned responses or primed memories that you usually recall without conscious awareness.

43
New cards

Explicit memories

“ Tell me about the best birthday you ever had”

also called declarative memories. Episodic, semantic, and prospective. You recall them with conscious awareness.

44
New cards

Working memory

Limited information, temporarily maintained, and used for many cognitive tasks, like remembering a password, imagining how new furniture could be placed, solving a math problem, or learning to change a flat tire. It is also called short term memory.

45

49
New cards

Echoic memory

Brief memory for auditory inputs, decays quickly, but not as fast as iconic. A part of sensory memory.

50
New cards

Short-term memory

Temporary storage of information that we attend to from our sensory memory.

51
New cards

Levels of processing model

knowt flashcard image
52
New cards

Shallow Processing: Structural

Encoding using the basic visual qualities of the word/concept. The shallowest level of processing.

“How many letters are in a word”

53
New cards

Shallow processing: Phonemic

Encoding is in the basic auditory qualities of the word/concept

“What does it rhyme with”

54
New cards

Encoding the meaning of the word. The deepest level of processing.

“Can you relate it to other concepts”

55
New cards

Method of Loci

An mnemonic device that relies on spatial relationships between locations on a familiar route or rooms in a familiar building to encode and later retrieve information

56
New cards

Correlational studies

Variables are not controlled, and random assignment to conditions aren’t utilized. They are different from experiments

57

63
New cards

Long-term memory duration

Stable throughout lifetime

64
New cards

Ebbinghau’s forgetting curve

Memorized nonsense syllables, tested himself at various times after memorizing them, and data was recorded. Very rapid loss of recall after an hour. Used to test long-term memory.

65
New cards

Explicit memories

Stored all of the brain and semantic networks. Areas of the hippocampus are essential for new formation of this type of memory.

66
New cards

Anterograde amnesia

When there is a problem, moving information from short term into long-term. Can cause your memory to ”reset each day”

67
New cards

Retrograde amnesia

Problem, retrieving explicit memories from long-term to working memory. Damage to some part of our cerebral cortex. Can’t remember past events.

68
New cards

Hippocampi

Two, one in each hemisphere. In charge of explicit memory and associated with themes and schemas.

69
New cards

Confirmation Bias

We do not want what really happened from our memory, we want the memory that will support what we are thinking and feeling. You will remember things how they want to be remembered.

70
New cards

Hindsight Bias

Our current cognitive and emotional needs will “rewrite“ a memory.

Ex: If you are angry, you will have trouble accessing a happy memory

71
New cards

Overconfidence

Our mind is convinced that what it produces is right.

72
New cards

Mood-congruent memory

Our emotions influence which memory is retrieved.

73
New cards

Context- dependent memory

Setting (sights and smells) help retrieval.

74
New cards

State Dependent memory

Memory pathways are only activew when you are in the certain mental/ emotional state.

75
New cards

Recognition

A type of retrieval. It is like a multiple choice questions and you know the answer because you recognize it.

76
New cards

Recall

A type of memory retrieval. It is like an FRQ question and you are accessing all of you information in your brain to answer it.

77
New cards

Testing effect

The more often you take a test, or work with a certain type of question, the better you become

78
New cards

Meta-Cognition

Thinking about your own thinking. Being aware of your own thinking is very difficult. Noticing what might be blocking information from appearing. Noticing what happens before the aha moment.

79
New cards

Incubation

You can’t make a fruit tree Bloom before it is ready. You can’t you exercising without taking a break. When you won’t answer, it is best to give your mind time to find the answer.

80

An event blocks or prevents retrieval of old memories.

86
New cards

Amnesia

Associated with storing and receiving information. You can or can’t remember.

87
New cards

Interference

Associated with processing information. Is what you are thinking of corrupted by information that was processed at a different time?

88
New cards

Retroactive interference

New information, corrupts, intertwines with, or blocks information that was processed at earlier time. Self consistency bias.

89
New cards

Proactive interference

Old information prevents, corrupts, or intertwines with current or recent information. Can’t teach an old dog new tricks.

90
New cards

Reconstructive memory

Is related to memory confabulation, which means our mind blends perceptions, and images from several experiences and gives it to us as what it believes is the record of what happened

91
New cards

Memory confabulation

Inaccurate details are often blended with what really happened

92
