Q

Describe the study by Cabeza et al., on autobiographical memory. (2)

A

-had participants take their own photos of the campus and put stock photos of the same buildings

70
Q

What are “phantom flashbulbs”?

A

-false memories of highly detailed, emotional events that people believe they experienced but did not, often due to misinformation or suggestion.

71
Q

What study did Neisser and Harsh (1992) conduct to investigate “phantom flashbulbs”?

72
Q

What did Neisser and Harsh (1992) find about memory errors in their study on phantom flashbulbs?

A

-hey found many serious errors in participants’ reports, although some were correct. Even showing participants their original recall failed to bring back the correct memory, and erroneous reports remained when interviewed six months later.

73
Q

What was the primary cause of the inconsistencies found in Neisser and Harsh (1992) study on phantom flashbulbs?

A

-incorrect sources of information (we confuse where we saw it first and have TV priority) and remembering the wrong time slice.

74
Q

What is “TV priority” in relation to phantom flashbulbs?

A

-mistaken recollection that participants heard about an event on television, even if they did not, (because TV is more visually stimulating)

75
Q

What is a “time slice error” in the context of flashbulb memories?

A

-occurs when participants vividly recall an occasion when they heard about an event, but it wasn’t the first instance

76
Q

What is a time slice error also known as?

A

-source monitoring error (not knowing the original source of information)

77
Q

Why do young people seem to have fewer flashbulb memories compared to older people?

A

-Young people might have fewer flashbulb memories because emotional events may not be as deeply impactful or memorable to them, and they may not have the same level of repeated exposure to the events that help solidify memories over time.

78
Q

If we experience something, does it become a flashbulb memory?

A

-No, it does not. It is only a flashbulb memory if it is something you heard of but not experienced yourself

79
Q

83
Q

What is blocking in Schacter’s “Seven Sins of Memory”?

A

-failure to retrieve information from long-term memory, often due to interference from other memories, such as the “tip of the tongue” phenomenon.

84
Q

What are the Sins of Commission in Schacter’s “Seven Sins of Memory”?

A

-include Misattribution, Suggestibility, Bias, and Persistence.

85
Q

What is misattribution in the context of memory?

A

-occurs when a memory is incorrectly attributed to the wrong source, leading to confusion about where the memory came from.

86
Q

What is suggestibility in Schacter’s “Seven Sins of Memory”?

A

-refers to the tendency for memory to be influenced by external suggestions, which can lead to the formation of false recollections.

87
Q

What is bias in the context of memory?

A

-influence of our current beliefs, expectations, desires, and emotions on what we remember, which can distort memories to fit our present views.

88
Q

What is persistence in the context of memory?

A

-refers to the continued, unwanted retrieval of a memory, particularly a distressing or unpleasant one, that we would prefer to forget.

89
Q

What are memory illusions?

A

-occur when the brain creates false or distorted memories, making us believe we remember something that didn’t happen or recall it incorrectly.

90
Q

What is déjà vu?

A

-feeling that you have previously experienced something, even though it is happening for the first time.

91
Q

What causes déjà vu according to the brain’s processes?

A

-The temporal lobe sends a message to decision-making regions of the brain, indicating that something has been experienced before. Prefrontal regions recognize the memory as incorrect, leading to confusion.

92
Q

Is déjà vu normal, and how often does it occur?

A

-Yes, déjà vu is normal and typically happens about once a month.

93
Q

What factors can increase the frequency of déjà vu?

A

94
Q

What is déjà vécu (already lived)?

A

-persistent déjà vu, where a person feels as though they are repeatedly reliving the same experience, like in the movie Groundhog Day. It can occur with dementia or as a result of drug use.

95
Q

What is jamais vu (never seen)?

A

-occurs when you fail to recognize that you’ve previously experienced something, even though you know you should. This phenomenon often happens under conditions of stress or fatigue.

Q

What is an example of Jamais vu?

A

-writing door over and over and thinking is it spelt like that?

97
Q

What did Bartlett’s war of the ghost experiment show?

A

-memories are constructive, our experiences and knowledge influence them
