Which of the following are characteristics of working memory?

Correct Answer(s) Its capacity is very limited. Information is available for less than 30 seconds. Information can be maintained through rehearsal. Incorrect Answer(s) Information is lost after 2 or 3 seconds. It holds information from one source at a time.

Which of the following features do flashbulb memories possess?

Correct Answer(s) People have confidence in their accuracy. They are extremely vivid. Their accuracy is high shortly after the event. Incorrect Answer(s) Their accuracy is high long after the event. Some have a strong emotional component, while others do not. They change very little over time.

Correct Answer(s) The effects of rehearsal appear stronger than the effects of suppression. Rehearsing information increases recall. Incorrect Answer(s) We cannot choose what we remember and what we forget. People who make no effort recall little of what they learn. Accurate recall of some memories requires the suppression of other memories. By practicing active suppression, we can choose to forget most of what we learn.

False

Identify each of the following scenarios as either free recall or cued recall.

Recite a poem from memory on the spur of the moment.- free recall A midterm includes the following question: "Write down twenty of the vocabulary terms from the last quarter, along with their definitions."- free recall "We finish each other's...""...sandwiches!"- cued recall Name ten people from grade school after looking at a yearbook- cued recall Answer multiple-choice questions- cued recall Name ten people from grade school without looking at a yearbook- free recall

In filmmaking, a "continuity error" refers to a mistake in which features of a scene appear to violate cause and effect. For example, in a scene shot in a bar, an angry patron might smash a beer bottle but after a switch in camera angles the bottle is visible again for a few seconds. Despite paying close attention to the screen, we seldom seem to notice these errors. Why is this?

The capacity of sensory memory is large but very short-lived, whereas the capacity of short-term memory is much smaller.

Caleb remembers being taken on a flight in a crop-dusting airplane as a child, but his parents insist that no such activity ever occurred. Since this is probably an example of a false memory, what can we assume about it?

The memory is based on the gist of what a flight would be like.

David is a stage magician who is famous for his close-up card tricks. Learning a new trick involves extensively practicing the same series of hand movements until they are second nature. If David practices for several hours a day, we would expect the brain areas associated with learning these motor plans to be as active during learning as they are several hours later.

True

Despite advances in our understanding of memory reconsolidation, it still isn't possible to selectively delete memories or associations.

True

Select all of the following statements that are true.

True Without rehearsal of new information, we quickly forget much more than we remember. According to trace decay theory, we forget information that we don't access. False All memory disorders consist of either misremembering or not remembering enough. Retroactive interference is caused by negative transfer of past memories.

Although most adults are unable to remember events prior to 3 years of age, some report particularly intense memories from earlier in life than that. Whether such memories are genuine or fabricated, however, remains controversial. Which of the following hypotheses has been put forward for how some people appear to have such early life memories?
