Q

Three stage model of human memory

A

  2. Process information into short-term or working memory, where we encode through rehearsal
  3. information can move into long-term memory for later retrieval

Deep processing

A

semantic processing:
happens when we encode the meaning of a word and relate it to similar words with similar meaning

Deep processing involves elaboration rehearsal, a more meaningful analysis of information and leads to better recall

inability to form memories from new material

can learn new facts, but have no memory of the source because of consolidation error

51
Q

Transience/Decay theory

A

unused memories fade gradually over time

52
Q

Interference theory

A

other memories interfere with retrieval

53
Q

Types of interference

A

Proactive, retroactive

54
Q

Proactive interference

A

When an old memory disrupts the learning and remembering of a new memory

55
Q

Retroactive interference

A

When a new memory blocks the retrieval of an old memory

56
Q

Absent-mindedness forgetting

A

Forgetting caused by lapses in attention (forgetting where you parked, losing keys)

57
Q

A

Form of interference related to the sequence in which material is presented

57
Q

A

forgetting when a memory cannot be retrieved because of interference

58
Q

Primacy

A

relative ease of remembering the first information in a series

59

A

Strong memories of the most recent information in a series

60

Misattribution (distortion)

A

When a memory is retreived, but associated with the wrong time, place, or person (TV rape example)

61
Q

Suggestibility (distortion)

A

Process of memory distortion as the result of deliberate or inadvertent suggestion

62
Q

Bias (distortion)

A

a memory tendency to distort recalled events to fit one’s expectations(ice cream)

64
Q

Self-consistency bias

A

A commonly held idea that we are more consistent in our attitudes and beliefs, over time, then we actually are
(thinking you have always loved ice cream, but in reality you hated it when you were younger)

65
Q

Persistence (intrusion)

A

Memory problem where unwanted memories cannot be put out of their mind

66
Q

transience is to ____ as suggestibility is to _____

A

forgetting, blocking

67
Q

Alzheimers disease

A

brain disorder that slowly destroys memory and thinking skills, and, eventually, the ability to carry out simple tasks

68
Q

Herman Ebbingham

A

Tested himself on memorization of random syllables, and forgot them over time, but he could relearn them in less time

69
Q

Overlearning

A

Process of rehearsing a skill even after improvement has stopped

70
Q

Connectionism model

A

Memories are products of interconnected neural networks. Everytime you learn something, your brains neural connections change, forming and strengthening pathways that allow you to interact with and learn from your constantly changing environment

71
Q

Alan Baddeleys model

A

1) Auditory rehearsal and Visual-spatial information
2) Central executive focuses our attention
3) Memories are pulled from long term memory to help make sense of new information

Q

Karl Lashley

A

Removed pieces of rats brains, and they still retained partial memory of how to get out of the maze

73
Q

What role does the basal ganglia play in memory

A

Facilitate formation of our procedural memories for skills

74
Q

Our conscious memory of our first four years is largely blank

75
Q

Eric Kandel

A

Observed synaptic changes during learning in the neurons of Cali sea slug

76
Q

Sea slug example

A

When learning occurs, slug releases more of the neurotransmitter serotonin into certain neurons. These cells synapses then become more efficient at transmitting signals

77
Q

What role does serotonin play in memory

A

Declarative memories that contain personal experiences, general facts, events

78
Q

81
Q

Encoding specificity principle

A

The idea that cues and contexts specific to a particular memory will be most effective in helping us recall it
